DESCRIPTION OF EMBODIMENTS

(25) Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

(26) Specific structural or functional descriptions of exemplary embodiments of the present invention disclosed in the specification are made only for the purposes of describing the exemplary embodiments of the present invention, and the exemplary embodiments of the present invention may be carried out in various forms, and it should not be construed that the present invention is limited to the exemplary embodiments described in the specification.

(27) Further, an embodiment according to a concept of the present invention may have various modifications and various forms and specific exemplary embodiments will be illustrated in the drawings and described in detail in the detailed description. However, it is not intended to limit the embodiments according to the concept of the present invention to the specific embodiments, and it will be appreciated that the present invention includes all modifications, equivalences, or substitutions included in the spirit and the technical scope of the present invention.

(28) In general, only when an abnormal is electrically separated from a house load group, it is possible to prevent broadcasting to a normal house load group from being stopped and further, it is possible to prevent a premises broadcasting output amplifier from being damaged.

(29) Therefore, a core goal of abnormal load analysis processing of the present invention is first to take an action in which the device according to the present invention autonomously electrically separates the abnormal load from the normal load group without delay by analyzing the abnormal load and second to allow an operating process to be executed simultaneously with marking or transmitting and controlling a corresponding analysis action result.

(30) Further, since the device according to the present invention needs to be inserted into an output side of an amplifier of a premises broadcasting device and individual house loads in terms of flow of an audio signal and the device according to the present invention needs to continuously perform abnormal analysis processing for each individual channel in real time, the device according to the present invention needs to be configured to perform functions of interested actions and results intended by an abnormal load analysis processing method.

(31) Moreover, since the device needs to be installed at a usage place of the premises broadcasting device, such as an industrial site or a public place and perform the functions, an exterior structure optimized for real usage and a structure of the device considering applicability and extensibility of electrical connection are required.

(32) Further, when a load of the premises broadcasting device may increase or decrease after initial construction of a load device at the house, when a determination reference value of the abnormal load is fixed to a predetermined integer value, a capability to cope with a load fluctuation situation is significantly limited, and as a result, whether a short, and the like occur may not actually be settled, as described in the prior art.

(33) Therefore, the present invention discloses a method that forms an initial reference value by receiving a load pattern value corresponding to a real load through receiving a sound output from an output amplifier of the premises broadcasting device in the early stage of executing abnormality analysis in a real usage environment, not by a limit load value detection protecting scheme of the output amplifier of the premises broadcasting device or forms the initial reference value by receiving an eigen load value corresponding to a real load pattern value from an external input means and converts and memories and generates the initial reference value according to a purpose and thereafter, continuously compares the initial reference value with a real-time used load pattern for each individual channel to analyze and process the initial load pattern value which is memorized and thereafter generated in the early stage of the execution with the real-time load pattern value which fluctuates by a specific method, thereby rapidly electrically separating only the abnormal load channel from the output amplifier of the premises broadcasting device and associating 4 logic output results including stand-by, short, disconnection, and normality with corresponding processes to processes the abnormal load and a device associated with the same.

(34) First, in order to describe the method, referring to FIG. 3, the method for analyzing and processing the abnormal load includes a generation step (S10), an analysis step (S20), and a processing step (S30).

(35) The generation step (S10) which is an execution process in the early stage of the abnormal load analyzing and processing includes processing processes of 2 load pattern elements 11, an early 2 tied calculation value 12, and a real-time 2 tied calculation value 13.

(36) Further, the analysis step (S20) of the abnormal load analyzing and processing includes processing processes of 2 condition inputs 21, 4 logic outputs 22, and an abnormality analysis command signal 23.

(37) Moreover, the processing step (S30) of the abnormal load analyzing and processing includes processes of control processing 31, result display and alarm processing 32, and transmittance control processing 33.

(38) In this case, in the analyzing and processing process according to the present invention, the early 2 tied calculation value 12 and the real-time 2 tied calculation value 13 generated in the respective processing processes of the generation step (S10) are processed as the 2 condition inputs 21 of the analysis step (S20) to transfer a result of the 4 logic outputs 22 of the stand-by, the short, the disconnection, and the normality to the processing step (S30) as the abnormality analysis command signal 23.

(39) In addition, in the processing step (S30), the output amplifier side of the premises broadcasting device and the load side are subjected to the electrical control processing 31, and the result is subjected to the result display and alarm processing 32 and subjected to the transmittance control processing 33 to the outside.

(40) Herein, the early 2 tied calculation value 12 represents a ratio (%) obtained by dividing an early load voltage value generated by converting the early load voltage value into a reference value and performing a target calculation of the converted value and storing the calculated value in the early stage of execution of the abnormal load analyzing and processing by an early load current value and in this case, the early load voltage value and the early load current value become 2 load pattern elements 11 in the early stage of the abnormality analysis.

(41) Moreover, the real-time 2 tied calculation value 13 represents a predetermined ratio (%) obtained by dividing a real-time load voltage value by a real-time load current value in usage real-time and in this case, the real-time load voltage value and the real-time load current value also constitute the 2 load pattern elements 11.

(42) That is, the 2 load pattern elements 11 include both two values of the load voltage value and the load current value in the early stage of the execution and two values of the real-time load voltage value and the real-time load value during the usage.

(43) In addition, concepts of residual terms will hereinafter be described through a detailed embodiment described below.

(44) Moreover, prior to detailed description according to the present invention, a connection pattern of the loudspeaker and the amplifier of the house is first described.

(45) When all premises broadcasting distribution lines are regarded as one load system, a systematic connection structure is final parallel connection. Therefore, in real life in which the output amplifiers are not used as many as the loads, even a short of a minority of unspecific loads of the same system or a short of only one load causes a short of the whole system.

(46) As a result, the broadcasting is immediately stopped in the whole system and barely, when the output amplifier of the premises broadcasting device is damaged, houses that accommodate the loads are defenseless to the broadcasting stop until a cause of the short is removed or a cause of the damage of the amplifier is removed and a recovery work is performed due to a short accident which occurs sporadically.

(47) However, according to the present invention, a harmful effect of the broadcasting stop may be prevented as described below.

(48) In FIG. 4 illustrating an influence which the individual short accident exerts on a loudspeaker distribution line group, all house loudspeakers 44 are connected in parallel regardless of the number of the house loudspeakers 44 and connected even with a premises broadcasting device output amplifier 42.

(49) Therefore, regardless of an initial stage and a final stage and regardless of a primary distribution line or a trunk distribution line or the front and the rear of a branch point of individual loads, since threshold of an unspecific short point 45 causes a whole short accident, the broadcasting is disabled in the entirety of an intermediate point house loudspeaker 44 including a final-stage house loudspeaker 43 regardless of existence of an input signal 41.

(50) In particular, when the short occurs in terms of the premises broadcasting device amplifier 42, a sound signal or operating power is cut off in an embedded output interruption unit or the corresponding protection device due to an overload and the amplifier thus stops, and as a result, the broadcasting secondarily stops on the whole again.

(51) In addition, even when the short occurs at speaker voice coils SP-1 and SP-2 of individual loudspeakers or at a secondary side of a matching transformer, the broadcasting is disabled and when the overload is applied to a primary coil of the matching transformer and heat is thus continuously dissipated, an additional short is subsequently caused due to inter-layer electrical breakdown of a primary winding coil and the broadcasting is disabled like damage of the speaker voice coils SP-1 and SP-2. Therefore, an influence of all short accidents of the individual house loads including the distribution lines exerted on a loudspeaker distribution line group brings out the whole broadcasting stop situation as described above at any point or any portion regardless of a type of a speaker load impedance value.

(52) However, in the present invention, when the short partially occurs in the individual houses or all loudspeakers which are connected in parallel, a result of electrically separating only the corresponding loudspeaker load from the premises broadcasting device output amplifier, displaying the separated loudspeaker load, and performing alarm processing may be obtained, thereby preventing the whole broadcasting stop situation which is the problem described above.

(53) In more detail, as illustrated in FIG. 3, in the generation step (S10), the early 2 tied calculation value 12 is calculated from the 2 load pattern elements 11 and stored in a storage table and thereafter, settled and generated as a comparison value to be provided as a first element of the process of the 2 condition inputs 21 in the analysis step (S20) which is a next process and further, the real-time 2 tied calculation value 13 in the usage real-time is generated from the 2 load pattern elements 11 to be provided as a second element of the process of the 2 condition inputs 21.

(54) In this case, for the abnormal load analyzing and processing, a reference value in the early stage of the execution needs to be compared or analyzed and processed as compared with a situation value of an electrical real-time load and as described above, the 2 load pattern elements 11 is constituted by the load voltage value and the load current value and two load voltage values and two load current values are provided in each of the early execution and real-time usage and the early 2 tied calculation value 12 and the real-time 2 tied calculation value 13 are generated through conditional calculation of the load voltage value and the load current value.

(55) Moreover, the early 2 tied calculation value 12 is generated by a scheme that target-converts the 2 load pattern elements 11 for achieving a ratio (%) of the load voltage value and the load current value which are 2 load pattern elements 11 in the early stage of the execution, target calculates the converted early execution load pattern 2 element values by averaging a plurality of early execution load pattern 2 element values in a unit time for accuracy of an analysis result, and stores the value in a corresponding memory table to determine the early 2 tied calculation value 12 which is a reference value of the abnormal which may be compared and analyzed with the real-time 2 tied calculation value 13.

(56) Thereafter, the target-converted usage real-time load voltage value and load current value as the real-time load pattern 2 element values, the designated real-time load pattern 2 element values are target-calculated and generated as the real-time 2 tied calculation value 13 and thereafter, two conditions (early 2 tied calculation value and the real-time 2 tied calculation value) are provided as 2 condition inputs 21, respectively in the analysis step (S20) which is a next step of the abnormal load analyzing and processing to be subjected to 4 logic analyzing and processing.

(57) In addition, the generation step (S10) which is a start step among the processing steps before the abnormal load analyzing and processing includes up to a step of providing an early reference value in the normal load to a non-volatile memory (see FIG. 16) of a 2 tied calculation value generating unit as an individual storage output value (see FIG. 15) so as to store and thereafter, generate the early 2 tied calculation value 12 from an early start for analysis as an early set-up step of the abnormal load analyzing and processing method according to the present invention.

(58) Moreover, in order to generate the load voltage value and the load current value which is 2 load pattern elements 11 at the early start of the abnormal load analyzing and processing, two methods of manual generation and automatic generation are provided according to input scheme classification and two methods may be selectively applied or both methods may be applied.

(59) For example, a manual input for the manual generation is a method that target-converts and applies the early 2 tied calculation value 12 for storage and generation by simply arbitrarily inputting a predetermined corresponding value by a universal input port or device from the outside as a means, such as generation by operating a PC, a mobile apparatus, or a body button or a program and when the early 2 tied calculation value 12 becomes a fixed value, since it is impossible to apply synchronization or optimization setting to a fluctuation real load, there is inconvenience that the early 2 tied calculation value 12 may not be flexibly applied to an increase or decrease in load or needs to be re-input afterwards, and as a result, it is preferable to provide an auxiliary means that may input the early 2 tied calculation value 12 and operating program data or upgrade an input value together by providing an external input through a wired/wireless communication network or an external input means such as a universal USB port, or the like.

(60) In addition, an automatic input for automatic generation allows the process to be performed by receiving a real-time sound output from the premises broadcasting device output amplifier in a real usage environment.

(61) Further, the load pattern 2 elements 11 are constituted by the load voltage value and the load current value in both the early stage of the abnormal load analysis and the usage real time and are applied as a means for storing and thereafter, generating the early 2 tied calculation value 12 illustrated in FIG. 16 through the early set-up process in the early stage of the execution of the abnormal load analyzing and processing and target-converted into the real-time 2 tied calculation value 13 illustrated in FIG. 16 in the usage real time of the abnormal load analyzing and processing to apply the early 2 tied calculation value and the real-time 2 tied calculation value which are first stored and thereafter, generated to be provided as two elements of the 2 condition inputs 21 to the analysis step (S20).

(62) In this case, in the abnormal load analyzing and processing, external load associated elements among elements which exert a primary influence on the load pattern are the load voltage value and the load current value of corresponding symmetric alternating current substantially within 20 Hz to 100 kHz.

(63) In addition, since power value [W]=voltage valuecurrent value (P=E.Math.I), a normal load voltage value and a normal load current value are in proportion to each other in terms of a load amount in fixed and variable loads of general characteristics and a voltage value of an audio signal in a general state varies at several periods or dozens of periods or more even at 1 second and each of a voltage value and a current value varies almost for very period regardless of an average value and a peak value in an audio signal which varies and when load voltage increases, load current also increases and when the load voltage decreases, the load current also decreases.

(64) According to the present invention, as the 2 tied calculation values are illustrate din FIG. 5, a load voltage value 57 and a load current value 58 have the same phase and are in progress on the same time axis 52 and a continuous temporal flow while maintaining a predetermined mutual ratio.

(65) Not an effective value of each of the load voltage value and the load current value but a comparison (%) width of the load voltage value and the load current value forms a predetermined tied calculation value, that is, the 2 tied calculation value in a predetermined load regardless of a specific load amount and an unspecific load amount in a load capacity size.

(66) The load voltage value and the load current value which are in proportion to the power value (load amount) are constant to a progress direction (time) and a change pattern of the audio signal and forms an eigen characteristic voltage-current relationship.

(67) As a result, since the values of the load pattern 2 elements 11 of FIG. 3 becomes the final early 2 tied calculation value 12 in the early set-up and the real-time 2 tied calculation value 13 in the usage real time, a level size and a period of the audio signal and the load amount vary limitlessly or widely, but the audio signal is in progress like first, second, third, . . . , N-th periods 53, 54, 55, . . . , 56 illustrated in FIG. 5, and as a result, when the load voltage value and the load current value are target-calculated for the abnormal load analyzing and processing, the 2 tied calculation value which is a ratio of the load voltage value and the load current value including the early stage of the execution and the usage real time may be obtained.

(68) Therefore, the load voltage value and the load current value required to obtain the early 2 tied calculation value 12 and the real-time 2 tied calculation value 13 are specified as the load pattern 2 elements 11.

(69) In particular, in the abnormal load analyzing and processing method, the early 2 tied calculation value 12 of the generation step (S10) is preferably configured by an average value of a conversion ratio (%) of the load pattern 2 elements 11, that is, the early load current value and the early load current value through the early set-up process which is the start process of the abnormal load analyzing and processing.

(70) Moreover, as described above, the early 2 tied calculation value 12 means a predetermined rate having an eigen property, which may be obtained in a conditional relationship between the early load voltage value and the early load current value of the alternating current, which are two elements of the load pattern in the early stage of the abnormality analysis and the early load voltage value and the early load current value which are two elements of the load pattern in the early stage of the execution of each period are individually changed according to output signal fluctuation and the load amount of the premises broadcasting device output amplifier in a phenomenon of a flow process of the audio signal, but a calculation value according to the present invention, that is, a ratio (%) obtained by dividing the target-calculated early load voltage value by the early load current value does not vary and the ratio (%) is specified as the early 2 tied calculation value 12.

(71) In more detail, as illustrated in FIG. 5, load voltage values 57 (V1, V2, V3, and Vn) for each period of the audio signal input from the premises broadcasting device output amplifier are provided and load current values 58 (I1, I2, I3, and In) for each period by an actual load amount of the premises broadcasting device output amplifier are provided and when the load voltage values and the load current values are diagrammatized with the same phase and the same time axis, if a difference between the load voltage value 57 and the load current value 58 corresponding to load values from the first period 53 to the N-th 56 is D1n, a relationship of (V1I1=D1)(V2I2=D2)(V3I3=D3)(VnIn=Dn) is established and D becomes the difference between the load voltage value 57 and the load current value 58.

(72) However, ratios (%) obtained by dividing the load voltage value by the load current value from the first period to the N-th period are Q1 to n, a relationship of V1/I1=Q1, V2/I2=Q2, V3/I3=Q3, Vn/In=Qn is established and Q is V1V2V3Vn and when a result of Q1=Q2=Q3=Qn is constantly obtained even under a condition of I1I2I3In and a condition of (V1I1=D1)(V2I2=D2)(V3I3=D3)(VnIn=Dn).

(73) Herein, the obtained tied result value, Q1 to n is set as the 2 tied calculation value.

(74) Therefore, as one example, a predetermined integer is substituted to calculate the 2 tied calculation value as described below.

(75) In a load of 50[], in the case of V1=100, V2=50, and V3=25, respective load currents I1, I2, and I3 are 100/50=2, 50/50=1, and 25/50=0.5 amperes, respectively.

(76) In the present invention, since it is specifically premises that 2 tied calculation value=load voltage/load current, 2 tied calculation value#1=100/2=50, 2 tied calculation value#2=50/1=50, and 2 tied calculation value #3=25/0.5=50, and as a result, the result values (ratio) are the same.

(77) That is, in the load of 50, even though supply voltages V1 to V3 for each period are changed to 100 [V], 50 [V], and 25 [V] and the load currents I1 to I3 are changed to 2 [A], 1 [A], and 0.5 [A], the 2 tied calculation value does not vary as 50.

(78) Further, in a load of 500[], in the case of V1=100, V2=20, and V3=10, respective load currents I1, I2, and I3 are 100/500=0.2, 20/500=0.04, and 10/500=0.02 amperes, respectively.

(79) In the present invention, since it is specifically premises that 2 tied calculation value=load voltage/load current, 2 tied calculation value#1=100/0.2=500, 2 tied calculation value#2=20/0.04=500, and 2 tied calculation value #3=10/0.02=500, and as a result, the result values (ratio) are the same.

(80) That is, in the load of 500, even though supply voltages V1 to V3 for each period are changed to 100 [V], 20 [V], and 10 [V] and the load currents I1 to I3 are changed to 0.2 [A], 0.04 [A], and 0.02 [A], the 2 tied calculation value does not vary as 500.

(81) The 2 tied calculation value calculated as described above may be formed as an eigen value corresponding to only the load value regardless of a change in amplitudes of the load voltage value and the load current value.

(82) In other words, even though input audio signal voltage is consecutively variably progressed at a limitless level of a graph level side 51 and a limitless time of a graph time axis 52 by passing through 0 (zero) which is a start point of the first period 53 in FIG. 5, a ratio (%) value of current to voltage in an entire area of the load may be continuously obtained to be the same while maintaining irrelevance with variation (period) values of the respective periods 53, 54, 55, and 56.

(83) In the case of The early 2 tied calculation value obtained by such a scheme, when the short occurs at the load side or the load amount varies due to any reason, the early 2 tied calculation value and the rate value (%) vary due to the load pattern 2 elements in real time, an effective appropriate measure command component for abnormal load analysis may be obtained by comparing and analyzing the early 2 tied calculation values and the rate values.

(84) Similarly, in FIG. 3, the real-time 2 tied calculation value 13 means a predetermined rate having an eigen property which may be obtained in a correlation between the real-time load voltage value (alternating current) and the real-time load current value (alternating current) which are two elements of the usage real-time load pattern and the real-time load voltage value and the real-time load current value which are two elements of the real-time load pattern are nominally changed at each period according to output signal fluctuation and the load amount of the output amplifier of the premises broadcasting device, but the calculation value, that is, the ratio between the real-time load voltage value and the real-time load current value which are target-calculated is not changed, and as a result, the ratio is specified as the real-time 2 tied calculation value.

(85) Since the real-time 2 tied calculation value is constituted by the usage real-time load voltage value and the usage real-time load current value as described above in the same progress step in which the early set-up process of the abnormal load analyzing and processing, a method principle presented by the present invention is fundamentally the same as the early 2 tied calculation value in association with FIG. 5 in the real-time 2 tied calculation value.

(86) Therefore, the real-time 2 tied calculation value is constituted by the real-time load voltage value and the real-time load current value which are the usage real-time load pattern 2 elements and the constituted real-time 2 tied calculation value becomes one of 2 condition input (21) elements of the abnormal load analyzing and processing step (S20) together with the early 2 tied calculation value which is finally stored and generated during the early set-up process.

(87) In the case of the early 2 tied calculation value, an average storage value is generated at one time in the early stage of the execution, and as a result, a goal during the process is achieved, but in the case of the real-time 2 tied calculation value, a predetermined 2 tied calculation value is continuously monitored during the flow of the audio signal which continuously fluctuates in usage real time and is continuously compared with the early 2 tied calculation value, and as a result, when a predetermined fluctuation amount is calculated and analyzed, analysis command processing may be performed in a control device.

(88) Meanwhile, in the analysis step (S20) is a step of transferring an abnormal analysis command signal to the corresponding elements in the processing step (S30) by receiving the early 2 tied calculation value 12 and the real-time 2 tied calculation value 13 generated in the generation step (S10) as 2 condition inputs 21 and classifying and outputting the 2 condition inputs 21 into the 4 logic outputs 22 (stand-by, short, disconnection, and normal states).

(89) In the abnormal load analyzing and processing method, the process after the generation step (S10) provides the method that specifies 4 logic output analysis based on 2 inputs in the analysis step (s20) and the 2 condition inputs 21 are the early 2 tied calculation value 12 and the real-time 2 tied calculation value 13 generated by target-calculated with the load voltage value and the load current value in the early stage of the execution or in real time, which are the load pattern 2 elements 11 of the abnormal load analyzing and processing start process and the 4 logic outputs 22 are specified as 4 classification result outputs of the stand-by, the short, the disconnection, and the normal state which are analysis results by logic input of the 2 condition inputs 21.

(90) Herein, the short is a comprehensive upward fluctuation load of the load including the distribution line as compared with the early 2 tied calculation value in a real load and the disconnection is a comprehensive downward fluctuation load of the load including the distribution line as compared with the early 2 tied calculation value in the real load.

(91) Moreover, the abnormal analysis command signal 23 which is 4 logic output 22 is transferred to the processing step (S30) which is a third-step process of the abnormal load analyzing and processing method to perform control processing 31 of electrically interrupting or maintaining the output side and the load side of the amplifier of the premises broadcasting device and the same analysis result is commanded to a result display and alarm processing 32 as an execution signal and a result value is subjected to wired/wireless transmittance control processing 33 to external related organizations.

(92) In addition, in the case of the 2 condition inputs 21, the early 2 tied calculation value 12 and the real-time 2 tied calculation value 13 generated in the generation step (S10) are received as the input elements.

(93) Further, since the essence of the early 2 tied calculation value 12 is the early load current value as compared with the early load voltage value, the early 2 tied calculation value 12 is generated and thereafter, stored as different result values for each load according to a change in the early load voltage value and the early load current value which are the load pattern 2 elements in the early stage and transferred to the process of the 2 condition inputs 21 of the analysis step (S20) as a first condition value among the 2 condition inputs.

(94) Moreover, since the real-time 2 tied calculation value 13 is an individual value of the real load corresponding to a real load pattern according to the change in real-time load voltage value and the real-time load current value which are real-time load pattern 2 elements as the real-time load current value as compared with the real-time load voltage value, the real-time 2 tied calculation value 13 is transferred to a process of the 2 condition inputs 21 of the analysis step (S20) as a second condition value among the 2 condition inputs 21 together with the early 2 tied calculation value 12 stored and formed in the early stage of the execution to generate (output) the 4 logic output 22 results and transfer the generated 4 logic output 22 results to the corresponding process after the abnormal load analyzing and processing and a correlation comparison condition equation of the early 2 tied calculation value 12 and the real-time 2 tied calculation value 13 corresponding to the 2 condition inputs 21 is shown as four types as shown in Table 1 given below.

(95) TABLE-US-00001 TABLE 1 Types 4 type conditions of 2 tied calculation value 1 Early 2 tied calculation value = 1, real-time 2 tied calculation value = 0 2 Early 2 tied calculation value < real-time 2 tied calculation value 3 Early 2 tied calculation value > real-time 2 tied calculation value 4 Early 2 tied calculation value = real-time 2 tied calculation value

(96) As shown in Table 1, a 2 condition equation of the early 2 tied calculation value 12 and the real-time 2 tied calculation value 13 is classified into 4 types.

(97) A first type is the early 2 tied calculation value=1 and the real-time 2 tied calculation value=0 and since the early 2 tied calculation value stored and generated in a 2 tied calculation value generating unit exists in the early set-up but the real-time 2 tied value does not exist, one value of the load current value and the load voltage value exists and the first type is a step in which there is no signal, and as a result, the corresponding state may be analyzed and processed through a predetermined calculation process and the 4 logic outputs 22.

(98) A second type is the early 2 tied calculation value<the real-time 2 tied calculation value and since the real-time 2 tied value is larger than the early 2 tied calculation value stored and generated in the 2 tied calculation value generating unit in the early set-up in real usage, the load amount increases as compared with the early stage of the execution, and as a result, the corresponding state may be analyzed and processed through a predetermined calculation process and the 4 logic outputs 22.

(99) A third type is the early 2 tied calculation value>the real-time 2 tied calculation value and since the real-time 2 tied calculation value is smaller than the early 2 tied calculation value stored and generated in the 2 tied calculation value generating unit in the early set-up in real usage, the load amount decreases as compared with the early stage of the execution, and as a result, the corresponding state may be analyzed and processed through the predetermined calculation process and the 4 logic outputs 22.

(100) A fourth type is the early 2 tied calculation value=the real-time 2 tied calculation value and since the early 2 tied calculation value and the real-time 2 tied value stored and generated in the 2 tied calculation value generating unit in the early set-up are the same as each other, and as a result, the load does not fluctuate. Therefore, the corresponding state may be analyzed and processed through the predetermined calculation process and the 4 logic outputs 22.

(101) In addition, in FIG. 3, a correlation of the early 2 tied calculation value and the real-time 2 tied calculation value which are the 2 condition input elements is subjected to predetermined calculation or logical output by the 4 logic outputs 22 in the process of the 2 condition inputs 21 of the analysis step (S20) to be analyzed and classified into 4 command values and a result value formed for an output is transferred to the processing step (S30) as the abnormal analysis command signal 23.

(102) In this case, the result value of the 4 logic outputs 22 by the 2 condition inputs 21 is classified into 4 states of the stand-by, short, disconnection, and normal states and the result value is shown in Table 2.

(103) TABLE-US-00002 TABLE 2 Analysis and Real-time Relationship of classification comparison of load Types 2 conditions result pattern 2 elements 1 Early 2 tied calculation Stand-by Load voltage = 0: value = 1, real-time 2 Load current = 0 tied calculation value = 0 2 Early 2 tied calculation Short Load voltage = 0: value < real-time 2 Load current = 1 tied calculation value 3 Early 2 tied calculation Disconnection Load voltage = 1: value > real-time 2 Load current = 0 tied calculation value 4 Early 2 tied calculation Normal state Load voltage = 1: value = real-time 2 Load current = 1 tied calculation value

(104) As shown in Table 2, 4 analysis results of the standby, short, disconnection, and normal states are transferred to the processing step (S30) as the abnormal analysis command signal 23 by the 2 condition equation relationship of 4 types.

(105) A first type is the early 2 tied calculation value=1 and the real-time 2 tied calculation value=0 and since the early 2 tied calculation value stored and generated in a 2 tied calculation value generating unit exists in the early set-up but the real-time 2 tied value does not exist, one value of the load current value and the load voltage value exists and the first type is a step in which there is no signal, and as a result, the corresponding state may be analyzed and processed as the stand-by state.

(106) A second type is the early 2 tied calculation value<the real-time 2 tied calculation value and since the real-time 2 tied value is larger than the early 2 tied calculation value stored and generated in the early set-up in the real usage, the load amount increases as compared with the early stage of the abnormal load analyzing and processing, and as a result, the second type is analyzed and classified as the short or upward fluctuation load state.

(107) A third type is the early 2 tied calculation value>the real-time 2 tied calculation value and since the real-time 2 tied value is smaller than the early 2 tied calculation value stored and generated in the real usage, the load amount decreases as compared with the early stage of the abnormal load analyzing and processing, and as a result, the third type is analyzed and classified as the short or downward fluctuation load state.

(108) A fourth type is the early 2 tied calculation value=the real-time 2 tied calculation value and since the early 2 tied calculation value and the real-time 2 tied value stored and generated are the same as each other, the load does not fluctuate in real time as compared with the early stage of the abnormal load analyzing and processing, and as a result, the fourth type is analyzed and classified into the normal state.

(109) An analysis and classification result obtained during processing the four types is settled as the abnormal analysis command signal 23 and a command value is transferred to the processing step (S30).

(110) Further, when the real-time comparison of the load pattern 2 elements is applied as a condition as necessary in Table 2, 4 logic output values may be just obtained as a result and for example, the stand-by state is a state in which since a load voltage condition is 0 while input signal voltage is 0, a load current condition is also 0 due to no current, the short state means a state in which the load voltage condition is 0 while a load current condition 1 and a state in which load current of 1 is abnormal load current which exceeds normal current and load voltage of 0 becomes short voltage in which residual drop voltage goes toward approximately 0 according to a degree of the short, the disconnection state is a state in which since there is no load while the load voltage condition is 1, the load current condition is 0, and the normal state means a state in which real used voltage is analyzed to be formed while the load voltage condition is 1 and real used current is formed while the load current condition is also 1.

(111) As described above, the 4 logic output analysis and classification result satisfies 4 elements required for abnormal analyzing and processing of the load of the premises broadcasting device.

(112) 4 results of the standby, short, disconnection, and normal states which are the analysis and classification result by the 4 logic outputs 22 become 4 abnormal analysis command signal 23 in the abnormal load analyzing and processing method of the present invention.

(113) In addition, the settled abnormal analysis command signal 23 (see FIG. 3) is transferred to the processing step (S30) to transfer a processing control command to the control processing 31, the result display and alarm processing 32, and the transmittance control processing 33.

(114) As such, a purpose of the processing step (S30) is to perform of the control processing 31 of a relay added between the output side of the amplifier of the premises broadcasting device and the load of the loudspeaker of the house based on the 4 logic output values of the abnormal analysis command signal 23, to perform the result display and alarm processing 32 to allow a management operator to intuitively identify the abnormal load state by commonly using visual and auditory means based on the 4 logic output values of the above abnormal analysis command signal 23, and to perform transmittance control processing 33 of the state and a processing or progress situation of the abnormal load based on the 4 logic output values of the above abnormal analysis command signal 23 to the external related organization through wired/wireless communication means as data.

(115) In this case, the control processing 31 constituting the processing step (S30) is a process for controlling a contact through a multi-contact relay or an electronic non-contact relay (solid state relay (SSR)) added between the output side of the amplifier of the premises broadcasting device and the load of the loudspeaker of the house by receiving the 4 logic output values of the abnormal analysis command signal 23 which is the analysis step (S20).

(116) NO and NC contacts of the relay may house a common terminal, an emergency terminal, a normal terminal, and the like and operate with a contact capacity of 100 [A], flux-magnetizing voltage, current of 50 [V] and 1 [A] or less, a delay time of 0.5 sec. or less, and supplied power voltage 100 [V] or less.

(117) When the NC contact is applied in the case where the abnormal load analysis result value is in the normal state, the corresponding relay may be actuated only in the short to thereby reduce all-time actuation power consumption.

(118) In the case of the control processing 31, a function of a speaker (load) selector may also be performed as the control processing (device).

(119) Further, the result display and alarm processing 32 constituting the processing step (S30) is used to allow the management operator to intuitively identify the state of the abnormal load by using the visual and auditory means in parallel by receiving the 4 logic output values of the abnormal analysis command signal 23 which is the analysis step (S20).

(120) To this end, display lamps and string arrays of the display of the stand-by, short, disconnection, and normal states may be distinguished with colors and separately read for each channel.

(121) An alarm sound has a structure in which vibration sound of a generation unit is directly transferred and a sign means that allows the alarm sound to be temporarily cancelled as necessary and announces that the alarm sound is cancelled is added.

(122) The result display requires an independent display step for each channel, but one alarm sound generating device is commonly used.

(123) Moreover, the transmittance control processing 33 is used to transmit the state and a processing or progress situation of the abnormal load based on the 4 logic output values to the external related organization through the wired/wireless communication means as the data.

(124) In this case, only when the transmittance control processing 33 is bidirectionally configured, the abnormal load analyzing and processing process may be operated and monitored externally remotely and a real load situation and a process progress state are transmitted together with the analysis result for each channel and remotely operated and configured at a third place.

(125) Further, in one example according to a preferred implementation method of the process that implements the generation step of the abnormal load analyzing and processing method, as illustrated in FIG. 6, memory place initialization is performed by memory initialization 61, error offset average value calculation 62 for reducing an error of the 2 tied calculation value described in FIG. 5 is performed based on the load pattern 2 elements 11 of FIG. 3, no-input processing 63 is performed when there is no input level signal from the output amplifier of the premises broadcasting device, no-load processing 64 is performed when there is no load including the short by examining the load side to store and generate the early 2 tied calculation value 12 obtained in FIG. 16 in the 2 tied calculation value generating unit 88 of FIG. 8 as a reference value in the early stage of the execution after synchronization with the device.

(126) In addition, in one preferable example of the process that implements the analyzing and processing step of the abnormal load analyzing and processing method, when the case in which there is no input level signal from the output amplifier of the premises broadcasting device and the case in which there is no load including the short are aggregated, no-input and no-load processing 75 is performed and a normal state limitless loop 76 is formed as illustrated in FIG. 7 and the early 2 tied calculation value 12 obtained in the 2 tied calculation value generating unit of FIG. 16 is stored and generated due to the early set-up process of the generation step of FIG. 6 and the analyzing and processing process of the 2 condition inputs 21, the 4 logic outputs 22, and the abnormal analysis command signal 23 is executed, however, when a voltage-current load pattern shown in the diagram of the 2 tied calculation value of FIG. 5 is V1/I1=Q1, V2/I2=Q2, V3/I3=Q3, Vn/In=Qn, it is determined to be normal in the case where (usage real-time Q1, Q2, Q3, Qn)=early reference value and it is determined to be abnormal and a short procedure 77 is performed in the case where (usage real-time Q1, Q2, Q3, Qn)>early reference value.

(127) Further, in the case where (usage real-time Q1, Q2, Q3, Qn)<early reference value, it is determined to be abnormal (short or downward fluctuation load) to perform an open procedure 78.

(128) The early reference value is the early 2 tied calculation value 12 generated by the 2 tied calculation value generating unit of FIG. 16.

(129) Moreover, when the load exits, in the case where the input signal level is smaller than a processing reference value, it is determined that the result is in the stand-by state while there is no signal. The result of the process needs to be the same as a 4 logic output result table of Table 2.

(130) An embodiment of a configuration of a device for analyzing and processing an abnormal load according to the present invention is described below.

(131) As illustrated in FIGS. 8 to 21, the device for analyzing and processing an abnormal load includes: input connection units 81 individually connected with respective output terminals of the amplifier of the premises broadcasting device; output connection units 82 connecting the plurality of input connection units 81 and the plurality of loudspeaker loads; load current converting units 83 of individual loudspeakers connected to the input connection units 81 in series; load voltage converting units 84 of the individual loudspeakers connected to the input connection units 81 in parallel; a load current amplifying and calculating unit 85 receiving a converted current change and performing proportional target calculation and outputting of the received current change; a load voltage amplifying and calculating unit 86 receiving converted voltage and performing of proportional target calculation and outputting of the received voltage; an early set-up unit 87 providing a reference value in the early stage of analyzing and processing to a next step as a storage value output 150 and storing and generating the provided reference value (see FIG. 15); a 2 tied calculation value generating unit 88 receiving the storage value output 150 and storing and generating an early 2 tied calculation value 12 in the early stage of the analysis in the early set-up unit 87 and generating a real-time 2 tied calculation value 13 in analysis real time and providing the corresponding data to an analysis step (S20) as 2 condition inputs 21; a 4 logic analyzing and processing unit 89 receiving and analyzing the early 2 tied calculation value 12 and the real-time 2 tied calculation value 13 as the 2 condition inputs 21 to determine stand-by, short, disconnection, or normal states and give a processing command as an abnormal analysis command signal 23; a control unit 810 opening or maintaining electrical connection of the output connection unit 82 and the input connection unit 81 according to a 4 logic analyzing and processing result; a result display and alarm unit 811 capable of visually and auditorily identifying the 4 logic analyzing and processing result; a transmittance control unit 812 transmitting or remotely input controlling analyzing and processing result data through wired/wireless communication; and a power supply unit 813 multiple constant power voltage.

(132) In this case, the input connection units 81 individually connected with the respective output terminals of the amplifier of the premises broadcasting device perform a primary function as connection units individually connected with the respective output terminals of the amplifier of the premises broadcasting device.

(133) In general, the input connection units may be configured to be as many as lines of the speaker selector of the premises broadcasting device or channels of the distribution lines of the individual loudspeakers of the houses or more than channels of the output amplifier of the premises broadcasting device.

(134) In addition, as a secondary function of the input connection units 81, an abnormal load analyzing and processing signal is supplied to the load current converting unit 83 and the load voltage converting unit 84 and output power of the amplifier of the premises broadcasting device is supplied to the output connection units 82 through the control unit 810, and as a result, the input connection units 81 is configured to have a relative relationship of control with the output control unit s82.

(135) In the case of a preferable example of the input connection units 81, as shown in FIG. 9, three terminals as the primary function, that is, each of C 94 as the common terminal, HOT 95 as the normal terminal, and EM 96 as the emergency terminal is constituted by one channel and is implemented as multiple individual channel input terminals, that is, CH-1(91), CH-2(92), . . . CH-N(93), and as a result, the number of channels may be applied or increased as necessary.

(136) In this case, since an array pattern of all of the individual channel input terminals is similar as three terminals, C 94 as the common terminal, the HOT 95 as the normal terminal and the EM 96 as the emergency terminal are disposed at the same array and in the case of a plug-in scheme, all of the individual channel input terminals are integrated as one or in the form of a binding connector for each group and a corresponding distribution line material is together provided to be connected with the output side of the amplifier of the premises broadcasting device as necessary and each terminal or distribution line material is distinguished with the corresponding color.

(137) Moreover, as the secondary function, in the step of connecting and providing the abnormal load analyzing and processing signal to the load current converting unit 83 and the load voltage converting unit 84, electrical interference among respective channels is configured to be minimized by relative small current design corresponding to signal processing and output power of the output amplifier of the premises broadcasting device is configured to be housed and mutually controlled by adjusting an allowable current capacity to load capacities of the individual loudspeakers of the houses with the output connection units 82.

(138) A current capacity of a connection point of the input connection units 81 and a connection system with the output connection units 82 are configured to be 100 [A] or less by considering up to a low impedance load (2 to 16) and inter-terminal withstand voltage is configured to be 200 [V] or less and in the case of the universal terminal based on maximum output voltage of 100 [V] of the output amplifier of the premises broadcasting device, up to a load of a maximum of 10 [KW] may be individually analyzed and processed.

(139) In this case, in the terminals C 94, HOT 95, and EM 96 of each of channels CH-1(91) to CH-N(93), a mutual conduction resistance value exceeds 1000[] or is configured by using electrical insulation as a principle, and as a result, indomitable circulation current and leakage current need to be minimized in spite of simultaneously applying multiple amplifiers.

(140) In addition, the output connection units 82 primarily perform the function as the connection units to which the individual loudspeaker loads and the loudspeaker loads of the houses including the distribution lines of the premises broadcasting device are individually connected.

(141) Therefore, the output connection units may be configured to be as many as the lines of the speaker selector of the premises broadcasting device or the channels of the distribution lines of the individual loudspeakers of the houses or more than channels of the output amplifier of the premises broadcasting device.

(142) Moreover, the secondary function is configured as a relative relationship of control having the input connection unit 81 and the connection unit 810 as a correlation condition.

(143) In the case of a preferable example of the output connection units 82, as illustrated in FIG. 10, three terminals as the primary function, that is, each of C 106 as the common terminal, HOT 105 as the normal terminal, and EM 104 as the emergency terminal is constituted by one channel and is implemented as multiple individual channel input terminals, that is, CH-1(101), CH-2(102), . . . CH-N(103), and as a result, the number of channels may be applied or increased as necessary.

(144) In this case, since an array pattern of all of the individual channel input terminals is similar to the input connection units 82 as three terminals, the C 106, the HOT 105, and the EM 104 are disposed at the same array and in the case of the plug-in scheme, all of the individual channel input terminals are integrated as one or in the form of a binding connector for each group and a corresponding distribution line material is together provided to be connected with the individual loudspeaker loads of the houses and each terminal or distribution line material is distinguished with the corresponding color.

(145) In this case, as the secondary function, the output power of the output amplifier of the premises broadcasting device supplied from the input connection units 81 through the control unit 810 is configured to be transferred to the individual loudspeakers of the houses by applying the allowable current capacity as the load capacities of the individual loudspeakers of the houses with the input connection units 81.

(146) In addition, a current capacity of a connection point of the output connection units 82 and a connection system with the input connection units 81 are configured to be 100 [A] or less by considering up to a low impedance load (2 to 16) and inter-terminal withstand voltage is configured to be 200 [V] or less and in the case of the universal terminal based on maximum output voltage of 100 [V] of the output amplifier of the premises broadcasting device, up to a load of a maximum of 10 [KW] may be individually analyzed and processed.

(147) Further, in the terminals C 106, HOT 105, and EM 104 of each of channels CH-1(101), CH-2(102), . . . CH-N(103), a mutual conduction resistance value exceeds 1000[] or is configured by using electrical insulation as a principle, and as a result, indomitable circulation current and leakage current need to be minimized in spite of simultaneously applying multiple amplifiers.

(148) Moreover, the load current converting unit 83 of the individual loudspeakers connected to the input connection units 81 in series obtains individual converted current values which are in proportion to the individual load current values that flow on the individual loudspeaker loads of the houses of the premises broadcasting device, which are received through the input connection units 81 as voltage components to provide the values to the load current amplifying and calculating unit 85 as the first element among the load pattern 2 elements 11.

(149) The load current converting unit 83 of the abnormal load analyzing and processing device, as illustrated in FIG. 11, inserts a primary coil corresponding to at least one of current transformers 117, 118, and 119 for each of all channels 111, 112, and 113 between the input connection units 81 and the control unit 810 in series in order for the output amplifier of the premises broadcasting device to simultaneously obtain individual analysis current outputs 114, 115, and 116 which are in proportion to the loudspeaker load current through the individual house distribution lines and pin layout structures coincide with each other so that polarities of the primary coil and a secondary coil are the same as each other.

(150) In the load current converting unit 83, in the case of the normal load, current corresponding to loudspeaker output capacities [W] of the individual houses or in the case of a short load state, full load current corresponding to short current flows on each primary coil and since an effect value of the current varies in synchronization with the audio signal which frequently varies regardless of the normal load or the abnormal load, in the secondary coil, signal current having the change phase is converted at a predetermined rate suitable for the abnormal load analyzing and processing to supply the value to an input terminal of the load current amplifying and calculating unit 85 of the abnormal load analyzing and processing device.

(151) Further, a characteristic which is first important in the load current converting unit 83 is minimization of insertion loss.

(152) In a minimized magnetic loop within a range to permit part mounting, secondary conversion is preferably achieved within a range in which the number of coils of the primary coil does not exceed one time or two times and it is necessary to endure a maximum allowable current value and a short current value of the load of the house.

(153) 10 [A] or less needs to be applied to a premises broadcasting device based on 100 [V] and up to 100 [A] needs to be applied to the low impedance load (2 to 16).

(154) As a second important characteristic, the device is preferably designed and configured so that a flat current conversion ratio characteristic in an entire area of audible audio frequency and up to 100 KHz as possible and usable sensitivity which is less influenced by a secondary circuit load connected to the secondary coil are obtained.

(155) Moreover, the load voltage converting unit 84 of the individual loudspeakers connected to the input connection units 81 in parallel obtains individual converted voltage values which are in proportion to the individual load voltage values that are applied to both ends of the individual loudspeaker loads of the houses of the premises broadcasting device, which are received through the input connection units 81 as voltage components to provide the values to the load voltage amplifying and calculating unit 86 as the second element among the load pattern 2 elements 11.

(156) In the load voltage converting unit 84 of the device for analyzing and processing the abnormal load, as illustrated in FIG. 12, the first coil part of the potential transformers 127, 128, and 129 for the entire channels 121, 122, and 123 is connected to each of both terminals C+EM or C+HOT of the input connection unit 81 in parallel in order to obtain individual voltage outputs 124, 125, and 126 for analyzing which are proportional to the voltage [V] corresponding to the output of the amplifier of the premises broadcasting device, and the pin arrangement structures of the primary and secondary winding coils coincide with each other to unify the polarities.

(157) In the load voltage converting unit 84, the voltage [V] corresponding to the output of the amplifier of the premises broadcasting device of the individual house is supplied to each primary coil, and as necessary, it is necessary to minimize the voltage applied to both terminals of the primary coil by inserting a decompression element having a non-inductive impedance value. In this case, the secondary coil is constituted to supply the value to the input terminal of the load voltage amplifying and calculating unit 86 of the device for analyzing and processing the abnormal load by transforming the change signal voltage applied to the input connection nit 81 at a predetermined ratio suitable for the abnormal load analyzing and processing.

(158) It is preferred that the important properties in the load voltage converting unit 84 are designed and constituted to obtain a transformation ratio which is flat up to possible 100 KHz as well as the entire audible audio frequency area and sensitivity less affected by the secondary circuit load (the load voltage amplifying and calculating unit) connected to the secondary coil.

(159) Further, since the potential transformers 127, 128, and 129 are applied for promoting the stable operation of the load voltage amplifying and calculating unit 86 by easily maintaining electric insulation from the output of the amplifier of the premises broadcasting device, a non-insulation type of decompression means or converting means with at least equivalent effect may also be applied to the load voltage converting unit.

(160) Meanwhile, the load current amplifying and calculating unit 85 calculating and outputting the proportional target by receiving the converted current change performs the matching process for satisfying the transfer characteristic required in the signaling process before and after receiving the converted current output of the load current converting unit 83 and the filtering process of removing unnecessary components, and performs a function of transferring the converted data value corresponding to the available load current to the A-D converter sample hold at the current side of the corresponding analyzing processor by constituting predetermined attenuating and element protecting devices required for the amplifying element 136 (see FIG. 13) to be included in the circuit.

(161) For example, as illustrated in FIG. 13, in order that the amplifying element 136 transfers the stable output current value proportional to the load current by receiving the converted current output 138 of the load current converting unit 83 of the entire channels CH-1 to CH-N to the processor sample hold input terminal, the current unit matching unit 131 performs level matching with the load current amplifying and calculating unit 85 by receiving the secondary current value of the load current converting unit, the current unit filter 132 attenuates unnecessary predetermined peak current and a noise harmonic component, the current unit attenuators 133 and 134 correct a proper input current level of the amplifying element 136 and set the value corresponding to the limit load on the signal current of the load current converting unit 83, the current unit protector 135 absorbs the unnecessary peak current which exceeds the functional limit of the four elements to remove the protection of the amplification terminal and the over-operation phenomenon, and the OP-AMP amplifying unit 136 outputs the output current value proportional to the predetermined input including the required functions to the current side 137 through the load current amplifying and calculating unit 85 to transfer the output current value to the corresponding processor A-D converter through the sample hold process.

(162) In this case, the load current amplifying and calculation unit 85 of the entire channels CH-1 to CH-N is insulated from the input connection unit 81 of the entire channels to minimize unnecessary electric interference in the output amplifier of the premises broadcasting device, the amplification terminal is a balance amplifier, the current unit attenuators 133 and 134 has the same electric characteristic, the limit voltage of the current unit protector 135 has a bi-directional characteristic within 1.2 [Volt], and the current unit matcher 131 and the current unit filter 132 add a reactor L as R+C if necessary to be flexibly applied according to the OP-AMP amplifying element 136 for amplifying the current to satisfy the used frequency characteristic and the dynamic range.

(163) In addition, the output of the load current amplifying and calculation unit 85 is represented as the transformed voltage, but classified as a function of the amplifying unit of the load current in the device of the present invention.

(164) Meanwhile, the load voltage amplifying and calculating unit 86 calculating and outputting the proportional target by receiving the converted voltage performs the matching process for satisfying the transfer characteristic required in the signaling process before and after receiving the converted output of the load voltage converting unit 84 and the filtering process of removing unnecessary components, and performs a function of transferring the converted data value corresponding to the available load voltage to the A-D converter sample hold at the voltage side of the corresponding analyzing processor by constituting predetermined attenuating and element protecting devices required for the amplifying element 146 (see FIG. 14) to be included in the circuit.

(165) In this case, as illustrated in FIG. 14, in order that the amplifying element 146 transfers the stable output voltage value proportional to the load voltage by receiving 148 the converted output of the load voltage converting unit 83 of the entire channels CH-1 to CH-N to the processor sample hold input terminal, the voltage unit matching unit 141 performs level matching with the load voltage amplifying and calculating unit 86 by receiving the secondary voltage value of the load voltage converting unit, the voltage unit filter 142 attenuates unnecessary predetermined peak voltage and noise harmonic component, the voltage unit attenuators 143 and 144 correct a proper input voltage level of the amplifying element and set the value corresponding to the limit load on the signal voltage of the load voltage converting unit 84, the voltage unit protector 145 absorbs the unnecessary peak voltage which exceeds the functional limit of the four elements to remove the protection of the amplification terminal and the over-operation phenomenon, and the OP-AMP amplifying element 146 outputs the output voltage value proportional to the predetermined input including the required functions to the voltage side 147 through the load voltage amplifying and calculating unit 86 to transfer the output voltage value to the corresponding processor A-D converter through the sample hold process.

(166) In this case, the load voltage amplifying and calculation unit 86 of the entire channels CH-1 to CH-N is insulated from the input connection unit 81 of the entire channels to minimize unnecessary electric interference in the amplifier of the premises broadcasting device, the amplification terminal is a balance amplifier, the voltage unit attenuators 143 and 144 have the same electric characteristic, the limit voltage of the voltage unit protector 145 has a bi-directional characteristic within 1.2 [Volt], and the voltage unit matcher 141 and the voltage unit filter 142 add a reactor L as R+C if necessary to be flexibly applied according to the OP-AMP amplifying element 146 for amplifying the voltage to satisfy the used frequency characteristic and the dynamic range.

(167) Meanwhile, an early set-up unit 87 providing, storing, and generating a reference value at the early stage of analyzing and processing to the next step as the storage value output 150 (see FIG. 15) perform a value corresponding to the analyzing and processing to a 2 tied calculation value generating unit 88 by outputting 150 a unique reference value of the early normal load as the early load pattern 2 element values through the automatic early set-up process or outputting 150 the same value as the reference value to the storage value through the passive early set-up process by an external input means.

(168) In this case, the reference value of the normal load at the early stage of the abnormal load analyzing and processing becomes a relative reference value of the abnormal analysis of the used real-time load.

(169) Accordingly, in the case of the automatic generation of the early reference value, a device is constituted to store and generate the reference value as the storage value output 150 in the 2 tied calculation value generating unit 88 by the load voltage value and the load current value of the load pattern 2 elements 11 of the early-stage normal load.

(170) In the case of the passive generation of the early reference value, a device is constituted to store and generate the same storage value output 150 as the reference value of the normal load in the 2 tied calculation value generating unit 88 by constituting a separate external unique value instead of the load voltage value and the load current value of the normal load to be directly associated with the storage value output 150 of the early step-up unit 87.

(171) In this case, in the case of the automatic generation of the early reference value, as illustrated in FIG. 15, the load current value and the load voltage value 151 by the load pattern 2 elements of the separate normal load is target-converted by receiving the amplifier output of the premises broadcasting device at the early stage of the abnormal load analyzing and processing to form the conversion value at the early stage and then the storage value output 150 for analyzing and processing the abnormal load is obtained by a load voltage value temporary storage 157, a load current value temporary storage 158, and a separate cumulative number temporary storage 159 through the signaling process. The storage value output 150 is constituted to provide the value to the 2 tied calculation value generating unit 88 which is a configuring device of the next analyzing and processing process and the 2 tied calculation value generating unit 88 is constituted to store, generate, and confirm the value in the non-volatile memory.

(172) Further, in the case of the passive generation of the early reference value, at the early stage of the abnormal load analyzing and processing, the early reference value of the separate normal load is directly received through the manual USB input 152 or a wired/wireless communication means as illustrated in FIG. 15 and set as the storage value output 150 without passing through the temporary storages 157 and 158 or the cumulative number temporary storage 159 to be provided to the 2 tied calculation value generating unit 88 which is the configuring device of the next analyzing and processing process, and the 2 tied calculation value generating unit 88 is constituted to store, generate, and confirm the early reference value in the non-volatile memory.

(173) Furthermore, the early set-up unit 87 may have an automatic input type of the early reference value through the automatic early set-up process and the passive generation which is the early set-up passive input type without passing through the temporary storage or the cumulative storage average value calculating process without generating the load pattern 2 elements 11 through the separate external input means to also be constituted by providing a bi-directional selection device or in combination without an input selector to analyze and process the abnormal load which is optimal to the use environment by selecting the early reference value input selector 153.

(174) The target-converting of the load current value and load voltage value is to ensure reliability in analysis result by repeatedly accumulating only an effective value in the cumulative number temporary storage 159 enough to ensure the accuracy of the abnormal load analyzing and processing by a predetermined number of times by removing the load current value and load voltage value which is less than the reference value and calculating an average value.

(175) In the temporary storage process, when the same temporary storage group as the number of channels of abnormal load analyzing and processing is set, three separate storages for load voltage, load current, and cumulative number are arranged in the group, the analyzing is performed, the load current value and load voltage value is target-converted to be converted into the load current value to the load voltage value suitable for the process procedure and recorded as the early set-up reference value in the temporary storage arrangement of the unique number.

(176) In this process, when the non-load processing 155 is classified, it is determined that there is no early reference value, and thus, the channel is recorded to 0 and the channel determined as the non-input is separated divided to be recorded as the early set-up reference value corresponding to the non-input processing 154 in the temporary storage arrangement of the unique number.

(177) As a result, the early set-up reference value provides a unique value required for the non-volatile storage space of the 2 tied calculation value generating unit 88 as the storage value output 150 of the early set-up unit 87.

(178) For flow pipe associated operation of the early set-up unit 87, the operation input device control function 156 is provided together.

(179) Further, the early set-up unit 87 stores and generates the early 2 tied calculation value 88 by receiving the storage value output 150 at the early analysis stage and generates a real-time 2 tied calculation value 13 in the analysis real time. The 2 tied calculation value generating unit 88 providing the corresponding data to the 2 condition input 21 during the analysis step (S20), as illustrated in FIG. 16, receives 161 the storage value output 150 formed by the early reference value in the early set-up unit 87 at the early stage of the abnormal load analyzing and processing to store the storage value output 150 in the non-volatile memory 163 and generate the storage value output 150 as the final early 2 tied calculation value 12 to transfer the generated value to first elements 173, 178, and 1713 (see FIG. 17) among the 2 condition input elements 172, 173, 177, 178, 1712, and 1713 (see FIG. 17) of the 4 logic analyzing and processing unit 89.

(180) In addition, the 2 tied calculation value generating unit 88 performs a function of generating a use real-time calculation value 166 (see FIG. 16) for analyzing and processing the abnormal load as the real-time 2 tied calculation value 13 to transfer the use real-time calculation value 166 to second elements 172, 177, and 1712 (see FIG. 17) among the 2 condition input elements 172, 173, 177, 178, 1712, and 1713 (see FIG. 17) of the 4 logic analyzing and processing unit 89.

(181) Particularly, in the configuration diagram of the 2 tied calculation value generating unit 88, the early set-up unit 87 receives the storage value output 150 at the early stage as the early storage value input 161 of the 2 tied calculation value generating unit 88 by forming, converting, and passing the early reference value of the separate normal load as the storage value output 150 and generates and confirms the storage value output 150 as the separate early 2 tied calculation value 12 through the drive interface 167 after target-processing through the EEPROM storage value interface 165 after being separately stored in the non-volatile memory storage arrangement 163. The generated and confirmed early 2 tied calculation value 12 is provided to the 4 logic analyzing and processing unit 89 by 0 to N channels as the first element of the 2 condition input 21.

(182) Further, in FIG. 16, the real-time relative value receiving the real-time calculation value input 162 is converted through the real-time calculation value interface 166 without the storage process in the real-time tied value arrangement 164 as the load value of the analyzing and processing real time to be confirmed and generated as the real-time 2 tied calculation value 13 through the drive interface 167 after being input to the processing process.

(183) The generated real-time 2 tied calculation value 13 is provided to the 4 logic analyzing and processing unit 89 of FIG. 8 by 0 to N channels as the second element of the 2 condition input 21 (see FIG. 1).

(184) As described above, the first generated early 2 tied calculation value output 12 and the later generated real-time 2 tied calculation value output 13 are provided as two inputs of the 2 condition of the 4 logic analyzing and processing unit 89 to calculate the abnormal load analyzing and processing result.

(185) The 2 tied calculation value generating unit 88 (see FIG. 8) may perform a function FUNCTION or synchronization SYNC to flow-operate an external device with the present device if necessary as an end of the generating step of the device for the analyzing and processing the abnormal load.

(186) The generation state after storing the separate early 2 tied calculation value 12 or the generation state of the real-time 2 tied calculation value 13 are informalized in the process of analyzing and processing the abnormal load to be transferred by a display or remotely. In the case where any one or both of the early 2 tied calculation value 12 and the real-time 2 tied calculation value 13 generated in the 2 tied calculation value generating unit 88 is not present, the case corresponds to an abnormal load analysis error to be recorded and listed for each event for managing together with alarming process or state transmission in addition to marking.

(187) Further, the 4 logic analyzing and processing unit 89 which determines as stand-by, short, disconnection, and normality and makes a processing command as the abnormal analysis command signal 23 (see FIG. 3) by receiving and analyzing the early 2 tied calculation value 12 and the real-time 2 tied calculation value 13 as the 2 condition input 21 performs a function of transferring the abnormal analysis command signal to the corresponding elements of the processing step (S30) by receiving the early 2 tied calculation value 12 and the real-time 2 tied calculation value 13 generated in the 2 tied calculation value generating unit 88 of the generating step (S10) as the 2 condition input 21 to classify and output the received values into the 4 logic outputs 22, as shown in FIG. 1 (stand-by, short, disconnection, and normality).

(188) In this case, the 4 logic analyzing and processing unit 89 is constituted to assign the real-time 2 tied calculation values 172, 177, 1712=A and the early 2 tied calculation values 173, 178, 1713=B of FIG. 17 generated in the 2 tied calculation value generating unit 88 as the 2 condition inputs 171, 176, and 1711 for each channel and receive the assigned values as the 2 condition input for the 4 logic analyzing and processing. In this state, an individual target value for analyzing whether the load is abnormal in the use real-time of the abnormal load analyzing and processing becomes the real-time 2 tied calculation values 172, 177, 1712=A and the individual early value of the early stage normal load of the abnormal load analyzing and processing becomes the early 2 tied calculation values 173, 178, 1713=B to receive the values in the 2:4 logic analyzing and processing devices 174, 179, 1714 as the 2 condition input 21 and transfer the 4 analysis results of the stand-by, short, disconnection, and normality as the result of the 4 logic output 22 according to a conditional correlation parameter of the condition input 21 to the control unit 810, the result display alarming unit 811, and the transmittance control unit 812 which are the three constituent elements 175, 1710, and 1715 of the processing step for each channel as the abnormal load command signal 23.

(189) The correlation parameter and the analysis result with the real-time 2 tied calculation values 172, 177, 1712=A and the early 2 tied calculation values 173, 178, 1713=B are classified as the following 4 types.

(190) First, in a first type, the early 2 tied calculation value 12 generated after being stored in the 2 tied calculation value generating unit 88 in the early set-up as A=0 and B=1 is present, but the real-time 2 tied value 13 is not present and thus, a case where either the load current value or the load voltage value is not present, that is, the non-signal step is analyzed and classified as the standby state.

(191) Next, in the second type, since the real-time 2 tied value 13 is larger than the early 2 tied calculation value 12 generated after stored in the early set-up as A>B in real use, a load amount to the early stage is increased to be analyzed and classified into the disconnection or the upward fluctuation load state.

(192) In addition, in the third type, since the real-time 2 tied value 13 is smaller than the early 2 tied calculation value 12 generated after stored in the early set-up as A<B in real use, the load amount to the early stage is decreased to be analyzed and classified into the disconnection or the downward fluctuation load state.

(193) Finally, in the fourth type, since the real-time 2 tied value 13 is equal to the early 2 tied calculation value 12 generated after stored as A=B, the load fluctuation does not occurs to be analyzed and classified into the normal state.

(194) The analysis classified result obtained in the 4 types of processing processes is confirmed as the abnormal analysis command signal 23 and the command values thereof are transferred to the 3 constituent elements 175, 1710, and 1715 in the processing step.

(195) That is, in the case of A=0 and B=1 which are the standby state of the first type, the abnormal analysis command signal of the 4 logic analyzing and processing unit maintains the electrical connection between the input connection unit 81 and the output connection unit 82 by the control unit 810 with an NC contact point, marks or selectively alarms the standby state in the result display alarming unit 811, and transfers the corresponding state to the transmittance control unit 812.

(196) In addition, in the case of A>B in the disconnection or upward fluctuation load state of the second type, the abnormal analysis command signal of the 4 logic analyzing and processing unit 89 interrupts the electrical connection between the input connection unit 81 and the output connection unit 82 by the control unit 810, marks or essentially alarms the disconnection or upward fluctuation load state in the result display alarming unit 811, and transfers the corresponding state to the transmittance control unit 812.

(197) Further, in the case of A<B in the disconnection or downward fluctuation load state of the third type, the abnormal analysis command signal of the 4 logic analyzing and processing unit 89 maintains the electrical connection between the input connection unit 81 and the output connection unit 82 by the control unit 810 with the NC contact point, marks or selectively alarms the disconnection or downward fluctuation load state in the result display alarming unit 811, and transfers the corresponding state to the transmittance control unit 812.

(198) Furthermore, in the case of A=B which is the normal state of the fourth type, the abnormal analysis command signal of the 4 logic analyzing and processing unit 89 maintains the electrical connection between the input connection unit 81 and the output connection unit 82 by the control unit 810 with the NC contact point, marks the normal state in the result display alarming unit 811, and transfers the corresponding normal state to the transmittance control unit 812.

(199) Meanwhile, the control unit 810 opening or maintaining the electrical connection between the input connection unit 81 and the output connection unit 82 according to the 4 logic analyzing and processing result performs a function of controlling the input connection unit 81 and the output connection unit 82 of the device of analyzing and processing the abnormal load by the abnormal analysis command signal 23 obtained as the analysis result in the 4 logic analyzing and processing unit 89.

(200) The control unit 810 is a configuration equal or similar to the example of FIG. 18, and a relay is recommended to use the mechanical contact point as long as there are no problems of space and operating current until an insertion loss limit of a semiconductor or a peak voltage breakage limit is overcome.

(201) In the device of the present invention, the relay is constituted to operate only in an emergency such as disconnection, and as illustrated in FIG. 18, the analyzed logic output is input to drive interfaces 184, 189, and 1814 of the driving circuit of the relay, and the replays 182, 187, and 1812 are constituted to operate to control the input connection units 181, 186, and 1811 and the output connection units 183, 188, and 1813 as rapidly as possible and be controlled within 1 second of 200 to 100.

(202) The electronic relay of the control unit of the device of analyzing and processing the abnormal load operates for maintaining the closed circuit when the disconnection, the normality, and the standby or opening the circuit only in the case of disconnection and thus, the contact point in the usual day is in a normal cross state.

(203) In the restoring and re-operating, the control unit depends to a processor command (the abnormal analysis command signal) of the 4 logic analyzing and processing unit without self-parameter or self-authority. The operation or the state of the control unit are constituted to be partially associated with the result display alarming units 175, 1710, and 1715 and constituted to be associated with the transmittance control unit 812 in the previous step.

(204) Further, the result display alarming and processing unit 811 (see FIG. 8) capable of visually and aurally distinguish the 4 logic analyzing and processing result is constituted to visually mark the state and the result analyzed and processed by the abnormal analysis command signal 23 obtained as the analysis result in the 4 logic analyzing and processing unit 89 and aurally performs a function of generating an alarm sound.

(205) The result display alarming unit 811, as illustrated in FIG. 19, is constituted to visually, and separately and regularly display the operation state (channel ON, OFF early set-up, alarm-OFF, or the like) and the abnormal analyzing and processing results (stand-by, short, disconnection, and normality) and aurally and regularly generate the alarm sound.

(206) That is, the analyzing and processing function of the corresponding channel operates by the separate channel switch 194, and the result is constituted by displaying the state as lighting on or off of a short and disconnection display lamp 191, a normal and standby display lamp 192, and a check display lamp 193.

(207) Further, the corresponding alarm sound of the entire channels is emitted through an alarm window 196 at the front of the device and may be interrupted by an alarm sound release button 195 if necessary, and in this case, the lighting display of the alarm sound release button lighted on or off to display a switch caution.

(208) In addition, since the individual channel operates, stops, or bypasses by each channel switch, the individual channel is constituted to select and release the analyzing and processing command, respectively when checking and repairing the abnormal distribution line among the plurality of distribution lines and starts to ON during the early stage operation. The three display lamps of the individual display unit may be applied as one multi-color display element while maintaining intuitiveness and may display the multiple states by varying each lighting-off period.

(209) The alarm sound may be alarmed by dividing the short and the disconnection with the cycle and the length of the control sound. When the result is displayed and operated by applying a text, a graphic display, or a touch type display, the function may be satisfied by simplifying the smaller structure or the control setting unit.

(210) Further, the transmittance control unit 812 to send the analyzed and processed result data through the wired/wireless communication or control the input remotely is constituted to transmit and control the analyzed and processed state and result by the abnormal analysis command signal 23 obtained as the analyzed result in the 4 logic analyzing and processing unit 89 to the external flow pipe device as the data through the corresponding wired/wireless communication means.

(211) The transmittance control unit 812 as the same or similar configuration as or to FIG. 20, sends the data such as the standby, short, disconnection, normal, or operating state and the result display to the required flow pipe device through the same corresponding protocol as RS-485Tx-Rx(207) or receives the remote control input to send information on the operation control or result and the state of the device of analyzing and processing the abnormal load through the wired/wireless internet network.

(212) The transmittance control unit 812 is constituted to send the corresponding information and input the remote control to a PC or a mobile phone by an applying means. That is, the transmittance control unit 812 is constituted to provide the state in the analyzing and processing process as operation information to an operating PC, a remote monitoring unit, or the like of the premises broadcasting device with a universal protocol format RS-485Tx-Rx(207) and the like through the dedicated communication conversion element 206 through the process interface 204 while performing the abnormal load analyzing and processing function by receiving the abnormal analysis command signal 23 of the 4 logic analyzing and processing unit 89 or implement the bi-directional remote operation control, and constituted to enlarge the corresponding information operation and control area of the abnormal load analyzing and processing by implementing the connection with a short-range wired communication network through the Ethernet driver 208 via the data interface 205, forming a short-range wireless communication network through a Bluetooth module 209 and implementing the connection to the mobile phone or the tablet PC, or connecting the wideband wireless Internet network through the Wi-Fi module 2010.

(213) In this case, the control executing state for each channel of the control unit 811 and the operation situation state for each channel of the result display alarming unit 812 are always input to the CPU microprocessor to be monitored at a place required for the analysis result and the state sending.

(214) In addition, the Ethernet driver 208, the Bluetooth module 209, and the Wi-Fi 33 module 2010 are accommodated in the device of analyzing and processing the abnormal load and a dedicated connection device or an antenna connection device is installed on the front and rear surfaces of the device.

(215) Furthermore, the power supply unit 813 supplying the multiple static voltage power is constituted to supply the power required for operating 8 configuring devices of the generating step (S10), the configuring device of the analyzing step (S20), and the three configuring devices of the processing step (S30), and the input power of the power supply unit 813 is configured to use commercial power and emergency DC power together.

(216) The power supply unit 813 as the same or similar configuration as or to FIG. 21, is constituted to supply a DC input terminal for blackout compensation or DC operation to a single power supply for emergency power and is set to 50 [V] or less by considering the versatility.

(217) In this case, the power supply unit 813 is constituted to operate as AC commercial power at ordinary times or to supply a required power to each constitute element of the device through a DC-DC converter or a filter and a regulator for stabilization.

(218) In addition, in FIG. 21, as three types or four types of stabilization power if necessary by receiving the AC commercial power 211 or the DC emergency power 212, a low voltage BUS 213 is supplied to a low voltage power requiring unit 216 corresponding to the load current amplifying and calculating unit 85+the load voltage amplifying and calculating unit 86, and a medium voltage BUS 214 which is relative medium voltage is supplied to a medium voltage power requiring unit 217 corresponding to the early set-up unit 87+the 4 logic analyzing and processing unit 89+the 2 tied calculation value generating unit 88+the result display alarming unit 811+the transmittance control unit 812, and the relative high voltage BUS 215 is supplied to a high voltage power requiring unit 218 corresponding to the control unit 810.
