The current alarm information is alarm information sent when the secondary equipment detects that equipment faults exist. The secondary device may be one or a plurality of secondary devices. The alarm secondary device refers to the failed secondary device. The target item operation parameters refer to operation parameters of equipment operation items to be subjected to fault detection corresponding to the secondary alarm equipment.

Specifically, the monitoring center monitors current alarm information sent by the secondary equipment, determines the secondary alarm equipment according to equipment identification in the current alarm information, and acquires equipment operation parameters corresponding to the secondary alarm equipment. And the monitoring center determines the alarm type according to the current alarm information, and acquires the target item operation parameters corresponding to the alarm type from the equipment operation parameters.
