[0052] In addition, the determination means 43 can determine the number of the electrical or electronic devices supplied from the power supply unit 100 by supplying or blocking power to the electrical or electronic devices from the power supply unit 100.

[0053] Hereinafter, a breaker 10 and an outlet 20 of the electrical device management system applied to the present disclosure will be described in detail with reference to FIGS. 3 and 4.

[0054] FIG. 3 is a circuit diagram illustrating the configuration of a breaker 10 used in the electrical device management system according to the present disclosure and FIG. 4 is a circuit diagram of the outlet 20 used in the electrical device management system according to the present disclosure.

[0055] In FIG. 3, the power supply unit 100 is composed of the breaker 10 and may be equipped with: a set of manual levers 11 provided between terminals R, S, T, and N on the supply line side supplied from external power lines and terminals U, V, W, and N on the load side of electrical devices and so on, respectively; a set of bimetal thermostats 12, each connected to each of the manual levers except a neutral line (terminal N); a set of current transformer (CT) 13, provided between the terminals R, S, T, and N on the supply line side and the terminals U, V, W, and N on the load side, respectively, to measure a current of each phase; and a zero phase current transformer (ZCT) 14 to measure a current between the supply line side of terminals R, S, and T and the load side of terminals U, V, and W.

[0056] Meanwhile, the power supply unit 100 in FIG. 4 is composed of the outlet 20 and equipped with a set of CT 13 to measure a current of each single phase; and a ZCT 14 to measure a current.

[0057] In addition, although it was described above that the voltage was measured by using a potential transformer (PT), it is not limited to this and the voltage may be measured by using an integrated circuit (IC) for voltage measurement. In addition, although it was expressed that current value was measured by using composition of CTs, it is not limited to this and a composition of a hall sensor or a current sensor would be well applied.

[0058] The measurement of a voltage and a current according to the present disclosure is performed by: a voltage measurement unit which is equipped with the PT to measure each of the line voltage and includes an analog-digital converter converting the measured value to a digital value; and a current measurement unit 22 which is equipped with an analog-digital converter converting the analog value measured by the CT 13 to a digital value as described above.

[0059] As described above, each measurement value measured in the voltage measurement unit 21 and the current measurement unit 22, respectively, is stored in a storage unit 35 through an arithmetic unit 30. Alternatively, a structure may well be provided to directly store each measurement value measured in the voltage measurement unit 21 and the current measurement unit 22, respectively, to the storage unit 35.

[0060] The arithmetic unit 30 is implemented by the MPU described above. In addition, depending on various conditions of a power analysis stored in the storage unit 35 composed of a memory, the arithmetic unit 30 can perform various power analysis for the voltage value and the current value outputted from the voltage measurement unit 21 and the current measurement unit 22, respectively.

[0061] For example, in the arithmetic unit 30, a power factor can be obtained through a calculation of a time difference between occurrences of zero point of the voltage V value and the current A value, respectively, and a resistance Q or impedance Z Q can be found through dividing voltage V value by current A. This can be simply expressed in equations as follows.

Apparent power VA=V*A

Active power W=V*A*Cos

Reactive power VAR=V*A*Sin

[0062] As described above, the apparent power, the active power, and the reactive power can be obtained for loads of the electrical or electronic devices.

[0063] In addition, when each of the apparent power VA, the active power W, and the reactive power VAR are multiplied by time hour, respectively, an amount of apparent power VAh, an amount of active power Wh, and an amount of reactive power VARh can be obtained.

[0064] Besides, in the arithmetic unit 30, a frequency Hz, higher harmonics (nth), an inrush current A, a voltage between phase V, a phase current A, an unbalanced voltage V, an unbalanced current A, and so on can be calculated.

[0065] In addition, for a predetermined period of time, a maximum value, a minimum value, and a mean value of these measured and analyzed values can be calculated and the measured values calculated like this may be stored in the storage unit 35 or transmitted to the management unit 60 through the control unit 40 and the communication unit 50 by wired and wireless communications.

[0066] Meanwhile, the control unit 40 controls the communication unit 50 to transfer calculated values calculated by the arithmetic unit 30 or power analysis data and so on stored in the storage unit 35 to the management unit 60. In addition, the control unit 40 receives a signal of the management unit 60 through the communication unit 50, and can control supplying and blocking of power in the power supply unit 100, accordingly. In addition, the control unit 40 can control to block the power supply in the power supply unit 100 in the case that measurement value in the voltage measurement unit 21 or the current measurement unit 22 deviates a range of measured values set in the storage unit 35 due to an occurrence of a leakage current, a short circuit current or a shock current.

[0067] In addition, up to now, although the arithmetic unit 30, the control unit 40, the communication unit 50 and the storage unit 35 have been described as an individual element of the composition, it is not limited to this and these may well be integrated into a chip composed of the MPU above. By providing above composition into a single chip, it can be easily installed in the outlet 20 which has a relatively small size.

[0068] In addition, the communication unit 50 is configured for wired and wireless communications to be implemented, for example, between a breaker 10 and a breaker 10, or an outlet 20 and an outlet 20, wherein breakers or outlets are adjacent.

[0069] Hereinafter, a process for sorting degree of connections of electrical devices automatically by the control unit of the electrical device management system according to the present disclosure will be described with reference to FIGS. 5 and 6.

[0070] FIG. 5 is a flow diagram illustrating a process for sorting a degree of connections of electrical devices automatically in an apartment complex according to the present disclosure.

[0071] In addition, in FIG. 5, though an apartment complex was described as an example for the sake of convenience, it is not limited to the apartment complex, and all electrical devices of a building, a factory, a large vessel, and so on can be applied.

[0072] In the following description, the recognition number will be described to increase a digit number thereof by one as an electric device goes down to be located at a lower stage in an electrical schematic diagram.

[0073] An electrical schematic diagram of the present embodiment is described as an example that an apartment complex is composed of nine apartment buildings and five shopping buildings 1A1E as illustrated in FIG. 5.

[0074] In the apartment complex, as a power supply unit 100, for example, a 1000 kVA transformer is provided, and this transformer is equipped with, for example, a main breaker of the complex which is configured to have a composition of the breaker 10 as illustrated in FIG. 3. The main breaker of the complex has a recognition number 1 of a first degree of connections. In the main breaker of the complex having the recognition number 1, the control unit 40 according to the present disclosure is provided.

[0075] Breakers and switches of a main distribution board of the complex supply power to each of the apartment buildings and shopping buildings and are assigned recognition number 11, 12, . . . , 1E of a second degree of connections, respectively, as shown in Table 1.

[0076] In FIG. 5, use of a multi tap of a room 307 of the apartment building 3 is described with reference to the electrical schematic diagram. In accordance with generation, sorting, and determination of the recognition number for the main breaker of the complex, a main breaker of the apartment building 3 is assigned to a recognition number 131 of a third degree of connections and a main breaker of the room 307 of the apartment building 3 is assigned to a recognition number 13171 of a fifth degree of connections. Like the recognition numbers 111E of distribution breakers of the apartment complex, recognition numbers 1311131E of distribution breakers of the apartment building 3, and recognition numbers 13171113171C of distribution breakers of the room 307 of the apartment building 3, recognition numbers are generated irrespective of orders of figures in the degree of connections.

[0077] The apartment buildings and shopping buildings of the second degree of connections in System No. column in Table 1 are written separately because charging systems thereof are different. That is, in the present disclosure, according to a setting in the control unit 40, electric charges can be automatically produced and managed by assigning different type of recognition number according to charging systems. Accordingly, management of electric charges can be efficiently implemented.

[0078] In addition, the apartment building 3 is divided into room 301, room 302, and so on and elevator 131B and so on. As shown in Table 2, four digit number of fourth degree of connections is assigned to each room. For example, the distribution breaker of the room 307 of the apartment building 3 is assigned to a recognition number 1317 of fourth degree of connections and the main breaker of the inside of the room 307 of the apartment building 3 is assigned to an five digit number of fifth degree of connections, therefore, the recognition of the main breaker of the room 307 of the apartment building 3 is 13171 of fifth degree of connections.

[0093] In the case that the determination means 43 recognizes, for example, 30 recognition numbers in a state that a circuit breaker as an electrical device having the highest degree of connections is ON and, for example, 10 recognition numbers in a state that the circuit breaker is OFF, then the number of electrical devices can be recognized as 20 which are disposed in a lower degree of connections under the circuit breaker having the highest degree of connections.

[0094] Therefore, according to the present disclosure as described above, when any one of electrical devices, even not having the highest degree of connections, is turned ON/OFF, the determination means 43 is able to recognize electrical devices in a lower degree of connections under that electrical device.

[0095] In addition, for the recognition number generated by the recognition number generator 41 in accordance with a determination of the determination means 43, the sorting means 42 is able to sort the degree of connections of electrical devices automatically by implementing ON/OFF of electrical devices in an initial period of electricity use or recognition of electrical devices. That is, since power as much as a variation in the use of electricity is transferred as is to electrical devices, outlet, transformer, and so on in the higher degree of connections of the same line, upper-lower degree of connections can be clearly classified.

[0096] In addition, since a variation of the power is reflected by a variation of not only a voltage and a current but also a change of a power factor, information on electrical devices can be easily determined by the determination means 43.

[0097] For example, in the case that power is not supplied to the main breaker of the room 307 of the apartment building 3, that is, in the case that the breaker having a recognition number 131 of higher degree of connections is OFF, recognition numbers of higher degree of connections and lower degree of connections with a recognition number 1317 as the center cannot be recognized.

[0098] In the case that the breaker having a recognition number 131 is ON, power is supplied to the main breaker having the recognition number 1317 of the room 307 of the apartment building 3, in FIG. 5. However, in the case that the breaker having a recognition number 1317 is OFF, although a user cannot recognize the upper and lower systems at the recognition number 131, the control unit 40 can recognize 141 upper systems and nine other systems, thus a total of 150 systems at the recognition number 1317.

[0099] In addition, in the case that the breaker having a recognition number 13171 of a room distribution board, provided in the room 307 of the apartment building 3, is OFF even though power is supplied since the breaker having recognition number 1317 is ON, the control unit 40 can recognize 150 upper systems and the recognition number 13171, thus a total of 151 systems at the recognition number 1317, and 151 upper systems at the recognition number 13171.

[0100] In the case that the breaker having a recognition number 13171 of a room distribution board in the room 307 is ON and each of 12 breakers in the room 307 in FIG. 5 is OFF, the control unit 40 can recognize 150 upper systems and the 13 lower systems, thus total 163 systems at the recognition number 1317, and 151 upper systems and the 12 lower systems, thus a total of 163 systems at the recognition number 13171.

[0101] In addition, in the case that the outlet 2 having a recognition number 131718 in FIG. 5 is ON, the control unit 40 can recognize 163 upper systems and the lower systems connected to the outlet 2.

[0102] Hereinafter a method of an automatic sorting of a degree of connections of Internet of Things and system recognition according to the electrical schematic diagram as described above will be described.

[0103] In the case that the power is not supplied from the power supply unit 100, even though, for example, a TV having a recognition number 131718111 is manipulated for ON/OFF operation as a user wants, through the Internet of Things, the control unit 40 does not work. That is, self-recognition number is not generated and other recognition numbers cannot also be recognized. Accordingly, power is not supplied to a load of distribution side even though the user manipulates ON/OFF operation through the Internet of Things.

[0104] In the case that the power is supplied from the power supply unit 100, the control unit 40 works irrespective of manipulation of ON/OFF operation, through the Internet of Things, of a TV having the recognition number 131718111, for example, as the user wants. Accordingly self-recognition number for the TV having the recognition number 131718111 is generated in the recognition number generator 41 and other recognition numbers of surroundings and the system are recognized and sorted in the sorting means 42, and then calculated and stored. Recognition numbers recognized at this time are at equal or higher degree of connections. In addition, although recognition numbers not directly related to a wiring system can be recognized, the recognized numbers of recognition numbers vary frequently depending on a sensitivity of wired and wireless communications. Accordingly, power can be supplied or blocked through Internet of Things to a load of distribution side for example by manipulating ON/OFF operation of the TV having the recognition number 131718111 as the user wants.

[0105] In addition, according to the present disclosure, a change of a variation in a voltage V and a voltage drop V, a current A and an earth fault current mA, a power factor %, a frequency Hz and so on of a power used in a lower degree breaker is simultaneously reflected into a breaker of a higher degree of connections by one and a breaker of higher degree of connections by two, upper and lower sides of a degree of connections can be clearly classified.

[0106] In addition, when a multi tap is installed to another outlet, the multi tap can also be determined by deleting an existing recognition number and regenerating a new recognition number at the outlet the multi tap is connected to.

[0107] Although the present disclosure accomplished by the present inventor has been described in detail according to an embodiment above, it is not limited to the above embodiment, and those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.

INDUSTRIAL APPLICABILITY

[0108] By using an electrical device management system according to the present disclosure, each electrical device in an electrical system is recognized and power consumption thereof can be controlled through Internet of Things. Furthermore, various electricity related safety accidents can be remarkably reduced by recognizing symptoms of accidents which may occur when electrical devices is controlled (ON/OFF) through the internet.
