[0080] The present invention utilizes an image monitoring system to collect the operating conditions and environmental conditions of each device in the substation, thereby performing regulation and control and ensuring the safe and normal operation of the power station, and sending information to the main station when an abnormal situation occurs.

[0081] The present invention utilizes a security protection system to detect at perimeter walls, gates, and various important areas. When someone illegally enters these important areas, the system issues an alarm, activates a local sound and light alarm, and links related equipment to give a reminder.

[0082] The present invention sends the data from the data acquisition system and the data monitoring system to the data processing system for analysis and processing to determine whether a fault occurs and to issue an alarm reminder when a fault occurs, including screening, shielding and querying of data signals, inferring fault information and processing it, analyzing fault data, determining fault information, including fault type, fault point, etc. At the same time, the data of each device in the station collected by the data monitoring system is verified with preset information to determine whether the data is accurate. The present invention performs fault judgment by constructing a fault judgment model, thereby realizing automated processing and analysis of faults, and at the same time uses periodically collected data to timely update the model, thereby improving monitoring efficiency and accuracy.
