DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] To achieve the aforementioned objective and effects, with regards to the technical means and structures as well as implementation methods utilized in the present invention, the characteristics and functions thereof will be hereunder set forth in details by means of preferred embodiments of the present invention along with appended drawings so as to comprehensively understand the present invention.

[0018] Refer first to FIGS. 1 and 2, wherein a flowchart and a block diagram of the present invention are respectively shown. It can be clearly seen from the Figures that, in the inspection method for early warning system of industrial security according to the present invention, an early warning system 1 comprises an inspection tool 11 and an inspection device 12 in order to perform inspection processes including the following steps:

[0019] (a) using a non-contact sensor 111 of the inspection tool 11 to collect relevant signal characteristics with regards to the periphery of a predetermined area in a factory;

[0020] (b) calculating on the collected signal characteristics by means of a processor 112 in the inspection tool 11 through the built-in predetermined programs of the processor 112;

[0021] (c) determining, based on the calculation results from the predetermined programs, the error point of the signal characteristics by means of the processor 112 in the inspection tool 11;

[0022] (d) the processor 112 determining the time that an abnormal phenomenon is about to occur in accordance with the data of the error point, sending out the signal characteristics in advance, transmitting the signal characteristics via a wireless transmission unit 113, and then storing in a storage unit 114; and

[0023] (e) receiving the warning information transmitted by the wireless transmission unit 113 by using a wireless transceiver unit 121 of the inspection device 12 and storing in a built-in database 122 for subsequent comparisons.

[0024] Next, refer conjunctively to FIGS. 2, 3, 4 and 5, wherein a block diagram, a coordinate graph of variations in environmental temperature, a curve graph of variations in environmental temperature and a partial enlargement view for the Portion A in FIG. 4 according to the present invention are respectively shown. It can be clearly observed from the Figures that the non-contact sensor 111 of the inspection tool 11 may be an infrared (IR) sensor, a hygrometer, a photo-sensor, a dust monitor or an air detector etc. so as to, by using the non-contact sensor 111, detect relevant signal characteristics about the variations regarding to the temperature, humidity, air concentration or dust/impurity contents or the like in the surrounding range of a predetermined area (e.g., the central control room, the power distribution system, the air conditioning system, the machining tool, the working mother machine or the electrical apparatus in a factory or the like.) Then the signal characteristics detected by the non-contact sensor 111 can be transferred to the processor 112 (such as a central processing unit (CPU), a microprocessor or a chip etc.) or a cloud database thus allowing further analyses with the predetermined programs. The processor 112 can store the signal characteristics in the storage unit 114, and the built-in predetermined program of the processor 112 can perform the Z-transform formula, as below:

[00002]$X\left(z\right)=Z.Math.\left\{x\left(n\right)\right\}=\underset{n=0}{\overset{}{.Math.}}.Math.x\left(n\right).Math.z^{-n.},$

to calculate, and then analyze and determine such obtained results based on a curve graph. FIG. 3 shows a general determination approach. The warning point can be configured in accordance with the Gauss distribution exhibited by the temperature statistics, in which the system setup X may issue a warning signal if 29 degrees has been surpassed by 3 degrees fifteen (15) times (i.e., T2 position) or alternatively the Max/Min limits have been surpassed by 10 degrees one (1) time (i.e., T1 position.) Herein, during the analysis operation, it can be based on the occurrence of an error point position (E) due to increase in temperature (it is possible to set the abnormal signal characteristic as upon the temperature exceeding 29 C.); then, through this error point position, it is possible to further apply the vector plane conversion or Z-transform to analyze the significant variation in temperature (shown as E.sub.1 in FIG. 5) to appreciate in advance that the occurrence of an abnormal signal (E.sub.0) is imminent. Furthermore, according to a priori analyses, it can be comprehended that the temperature signal characteristics in the inspection area are about to change abnormally, so the processor 112 in the inspection tool 11 may, based on the analysis results, issue a warning message through a warning unit 115 (e.g., an alarm lamp, a buzzer or a speaker or a microphone for communication etc.) thereby allowing relevant staffs or personnel in that area to deal with such situations to prevent accidents and reduce the possibility of occurrence of potentially dangerous events in order to effectively achieve the industrial security premonitory function.

[0025] The inspection tool 11 can be used to detect each area in a factory individually, and the analysis signals obtained from the variations generated by various environmental signal characteristics (e.g., temperature, humidity, air concentration or dust/powder impurities etc.) in that area by means of the non-contact sensor 111 of the inspection tool 11 can be transferred to the inspection device 12 via the wireless transmission unit 113 such that the wireless transceiver unit 121 in the inspection device 12 receives the analysis signals sent by the wireless transmission unit 113. In addition, the wireless signals transferred between the wireless transmission unit 113 and the wireless transceiver unit 121 may be wireless signals conforming to Zigbee, Z-wave, Bluetooth, Wi-Fi, WiMAX, light communication or Sub-G and so forth. The inspection device 112 may store the received analysis signals in the database 122 such that, during the next inspection operation on the same area, the inspection device 12 may transfer the analysis signals related to that area to the wireless transmission unit 113 via the wireless transceiver unit 121, so that the processor 112 in the inspection tool 11 can receive the analysis signals of previous inspections and then compare them with the currently acquired analysis signals or the signal characteristics saved in the storage unit 114 in order to determine the occurrence of abnormal phenomena in the environment of that area through analysis signal comparisons to seek appearance of significant variations, thus allowing the inspection staffs to more precisely appreciate and control any changes in the environmental signal characteristics of the inspection area. Of course, the analysis signals provided by the aforementioned processor 112 can be re-evaluated in the database 122 again in order to determine whether any abnormal change occurs in the surrounding range of the inspection area, and since the industrial inspection is performed through the non-contact sensor 111 of the inspection tool 11 in each area of the factory or facilities, this may require less manpower and lower budgets, thus offering advantages like time-saving, work-saving and economical effects, and also the inspection can be repeatedly performed within shorter period of time, thus enabling improved industrial security maintenance for industrial factories and reduced damages and losses caused by accidents. Besides, the storage unit 114 of the inspection tool 11 may store or install a certain preset programs such that, upon using the inspection tool 11 to executing inspections, the sampled temporary or backup data can be provided to the processor 112 as the reference for comparison and analysis operations.

[0026] The inspection tool 11 may be also applied to detect the temperature variations in a chemical pipeline. By monitoring the temperature deviation coefficient on the wall of the pipeline, the processor 112 may determine whether the chemical liquid therein is appropriate for subsequent processes under such a temperature fluctuation; in case the temperature deviates too much or becomes out of a suitable range, the chemical pipeline may stop delivering and a suitable heating or cooling operation may be executed in order to ensure the thermal reservation effect can be actually achieved for improved product yield rates.

[0027] Upon detecting relevant signal characteristics regarding to the variations in temperature, humidity, air concentration or dust/powder impurities etc. in the surrounding zone of the predetermined area (e.g., the central control room, the power distribution system, the air conditioning system, the machining tool, the working mother machine or the electrical apparatus or the like), certain issues like component aging problems in the machines or equipments within the inspection area or measurement deviations in the processor 112 of the inspection tool 11 might be ignored during inspection operations, but such issues could be critical information concerning the industrial security of the inspection area as well. Therefore, through various kinds of data stored in the database 122, the inspection device 12 can compare and analyze the environmental temperature, voltage, current and wireless signal intensity of the inspection area in order to further determine the differences between data signals thereby compensating the difference signals among the components within such tools or equipments and achieving the auto-correction function in the inspection tool 11. In this way, the inspection tool 11 may provide more precise deviation coefficient determinations and discover beforehand the fluctuations in the signal characteristics of the inspection area so as to send out a warning notice for precautionary measures.

[0028] Accordingly, the descriptions set forth as above all illustrate simply the preferred embodiments of the present invention, rather than restricting the scope of the present invention thereto. The inspection method for early warning system of industrial security according to the present invention provides an early warning system 1 comprising an inspection tool 11 and an inspection device 12, which uses the non-contact sensor 111 of the inspection tool 11 to perform environmental detections in a predetermined area, applies a processor 112 to analyze based on the detected signal characteristics (such as temperature, humidity or dust/powder densities etc.) in order to determine the time that an abnormal signal is about to appear thereby enabling relevant personnel or staffs in that area to take corresponding measures thus achieving the purpose of reducing the possibility of industrial security accidents. Moreover, it is possible to, through a wireless transmission unit 113 in the inspection tool 11, transfer the signal characteristics analyzed by the processor 112 to the inspection device 12 such that a wireless transceiver unit 121 can receive the analyzed signals and then store them in a database 122 as the comparison references for subsequent detections. Consequently, it should be noticed that all structures and devices capable of achieving the aforementioned effects are covered by the scope of the present invention, so all such modifications and equivalently structural changes reasonably fall within the scope of the present invention.

[0029] As such, the present invention essentially provides an inspection method for early warning system of industrial security, in which it applies a non-contact sensor of a inspection tool to detect a predetermined area, transfers the inspected signal characteristics to a processor for analyses in order to determine whether an abnormal signal occurs therein such that relevant precautionary operations may be executed in that area thereby enhancing the industrial security and reducing the possibility of industrial security accidents. In this way, the inspection processes may require less manpower and lower budgets, thus offering benefits such as time-saving, work-saving and economical effects, and the inspection tool can repeatedly operate to inspect within short period of time, thereby allowing precise analyses on industrial security inspections for industrial factories, precautionary operations and reduction of damages and losses caused by accidents. The above-mentioned illustrations, however, is merely the preferred embodiments of the present invention, rather than accordingly to limit the scope of the present invention. Therefore, it can be appreciated that all convenient modifications and structural variations of equivalent effects based on the contents of the specification and appended drawings should be reasonably deemed as falling within the scope of the present invention.
