[0039] pass Determine the stability changes of the associated equipment before and after the fault occurs, and then When judging that a fault or hidden danger has occurred, the synchronization of the operating information changes of the related equipment and the main equipment of the fault improves the accuracy of the judgment of the maintenance target, thereby ensuring that all fault-related equipment can be repaired during a single shutdown process, avoiding multiple shutdowns, and at the same time, by automatically judging the maintenance target, the time required for maintenance is shortened, thereby effectively shortening the downtime and reducing the economic losses caused by the downtime.
