The computer 200 analyzes a transmission signal of each of the transceivers 100 connected to the electrical equipment facility 400 by using a corresponding protocol and collects and analyzes the information to analyze and transmit alarms, A detected information reply step (S25) of extracting specific information from the displayed and analyzed information, characterizing the extracted information, and returning it to the set mobile device (300);
(S30) requesting specific information of the specific electrical equipment facility (400) to the computer (200) through the mobile device (300);
(S35) converting the wire / wireless communication signals received by the computer 200 via the wireless / radio transceiver 201 into character information to be converted into program information;
Receiving the information requested by the mobile device 300 from the character management program 220 and analyzing the mobile information and the encrypted data to obtain request information (S40);
The encrypted data is analyzed through the DATA encryption and code information checking program 230 to determine whether the specific information requested from the mobile device 300 is valid and whether or not to reply is determined according to the status of the determined information. Extracting the requested information about the information request and transmitting the extracted information to the signal transmission module 120 (S50);
The signal transmission module 120 analyzes the encrypted protocol data and receives information about the information requested by the computer 200 from the detection sensor 110 to be provided with the status of the electrical equipment facility 400 in real time After receiving the information, the computer 200 analyzes the protocol and transmits the information to the corresponding mobile device 300 (S60). Wherein the mobile communication system comprises a mobile bidirectional character transmission / reception system having a security function.
8. The method according to claim 6 or 7,
In the step S50 of transmitting the analyzed information of the DATA encryption and code information checking program 230 to the signal transmission module 120, if the specific information requested from the mobile device 300 is not registered or the permission is not set It is possible to request information of the electric equipment facility 400 or to restrict the information to be returned when the mobile device 300 does not agree with the promised algorithm of the data encryption and code information inspection program 230, Wherein the mobile terminal returns a restriction content when the mobile device is unauthorized or unauthorized even if the mobile device is a mobile device.
