Referring to FIG. 7 , the electrical panel safety detection and abnormality check system according to an embodiment of the present invention automatically detects whether the electrical panel 10 is energized by a pre-detection algorithm set in the control module 230 of the central server. can make it happen

In more detail, the control module 230 may change the flow of energization detection of the electric panel 10 by the detection module according to the operation of the pre-sensing algorithm.

At this time, when a power cut signal is input to the electric panel 10, the control module 230 checks whether the pre-detection algorithm is in operation, and when the operation is performed, the door 10 is opened or the pressure is not detected in the door handle Also, it is possible to operate the energization detection sensor 130 of the detection module 100 only by inputting a power cut signal.

At this time, when the energization is confirmed as a result of analyzing the detection signal generated by detecting the voltage value in the corresponding electric panel 10 by the energization detection sensor 130 by the monitoring analysis module 220, the instantaneous door locking device The door 11 of the electric panel 10 may be forcibly locked by controlling the

At this time, when the door locking device is controlled by the control module 230 and forced locking is performed, the voltage value flowing through the electric panel may be additionally measured by the energization sensor 130, and additionally the energization sensor 130 When energization is not confirmed when the detected signal measured by operation is analyzed, the door lock can be released.

That is, when the pre-sensing algorithm operates, the energization detection sensor automatically operates at the moment when a power cut signal is input to the electric panel 10 to determine whether power is energized. Thus, the door 11 of the electric panel 10 is forcibly locked, and in the state where the door 11 is forcibly locked, the energization detection sensor 130 continuously operates to analyze whether electricity is energized, so that electricity does not flow. When it is confirmed, it is possible to control the door locking device to release the forced lock of the door 11 .

In addition, when the pre-sensing algorithm does not work, when the pressure inputted at the moment the operator grips the door 11 is sensed, the energization sensor 130 operates to analyze whether energization is present.

As described above, the electric panel safety detection and abnormality inspection system according to an embodiment of the present invention analyzes the results of measuring whether electricity is energized and the current value according to the situation by using a detection module in an electric panel installed in an industrial facility. It is possible to determine the possibility of electric shock and the abnormality of internal components.

In addition, it is possible to provide an electric panel safety detection and abnormality check system that allows the operator to immediately recognize the possibility of electric shock prior to work, and enables rapid maintenance when detecting abnormalities in internal components.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto. is within the scope of the right.
