The communication unit 40 acquires the internal memory data of the PLC module 51 acquired from the PLC module 51 and transfers the internal memory data to the failure determination unit 20. The failure determination unit 20 receives the internal memory data from the communication unit 40 The internal memory data of the received PLC module 51 and the preset normal data mapped to the internal memory of the failure judging unit 20 are compared with each other, Is in an abnormal state.

If the failure judgment unit 20 determines that the remote control 50 is in an abnormal operation state, the failure judgment unit 20 transmits a message indicating that the remote control 50 is in an abnormal operation state to the central control server 200 through the communication unit 40 And a message transmission unit 30 for transmitting the message.

That is, when the failure judging unit 20 judges that the remote control panel 50 is in the abnormal operation state, the failure judging unit 20 judges that the abnormality has occurred in the abnormality operating state And transmits the abnormal operation state information to the message transmission unit 30. The message transmission unit 30 transmits the abnormal operation state information to the central control server 30 connected to the communication network 100 through the communication unit 40, 200 or a message of abnormal operation state information to the mobile communication terminal 300 of the administrator of the central control server 200 in the SMS (Short Message Service) mode or the push mode. Accordingly, the manager of the control server 200 can determine whether the corresponding module in the abnormal operation state displayed in the central control server 200 or the mobile communication terminal 300 that received the abnormal operation state information of the remote control board 50, Information on the name and state of the equipment can be recognized in real time, and recovery measures of the corresponding remote control 50 can be performed quickly.
