At this time, when a power cut signal is input to the electric panel 10, the control module 230 checks whether the pre-sensing algorithm is operating, and when it operates, the door 10 is opened or no pressure is detected on the door handle. Even in this case, the energization detection sensor 130 of the detection module 100 can be operated simply by inputting a power cut signal.

At this time, if energization is confirmed as a result of analyzing the detection signal generated by detecting the voltage value in the corresponding electrical panel 10 by the energization detection sensor 130 by the monitoring analysis module 220, the door lock device is locked at the moment of confirmation. The door 11 of the electric panel 10 can be forcibly locked by controlling, and if power is not confirmed, the forced locking of the door can not be implemented or can be released.

At this time, when the door lock is controlled by the control module 230 and forced locking is performed, the voltage value flowing through the electric panel can be measured by the energization detection sensor 130, and additionally the energization detection sensor 130 When operating and analyzing the measured detection signal, if electricity is not confirmed, the door lock can be released.

In other words, when the pre-detection algorithm operates, the energization detection sensor can be automatically operated at the moment a power outage signal is input to the electric panel 10 to determine whether energization is present, and when energization is confirmed, the door lock is controlled. The door 11 of the electrical panel 10 is forcibly locked, and while the door 11 is forcibly locked, the energization detection sensor 130 continuously operates to analyze whether or not electricity is flowing, confirming that electricity is not flowing. When confirmed, the door lock can be controlled to forcefully unlock the door (11).

Additionally, if the pre-sensing algorithm does not operate, the energization detection sensor 130 can be operated to analyze whether energization is present when the pressure input at the moment the worker grips the door 11 is detected.

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

In addition, it is possible to provide an electrical panel safety detection and abnormality inspection system that allows workers to immediately recognize the possibility of electric shock before work and allows prompt maintenance when abnormalities in internal components are detected.
