Online on-off operation checking method based on maintenance plan

An online on-off operation checking method based on a maintenance plan relates to an online checking method. At present, scheduling personnel can confirm on-off operation by manually searching the maintenance plan, which is low in efficiency. The method comprises the following steps: 1) structuring the maintenance plan: standardizing the maintenance plan according to structuring requirements, and structuring maintenance plan service stop date, plan approving time, factory names and main work content in the maintenance plan; 2) capturing switch displacement warning information: when a switch displacement signal is generated, transmitting the switch displacement warning signal according to a naming structure; 3) carrying out online checking on the on-off action based on the maintenance plan: scanning the maintenance plan items and matching the on-off action; and 4) outputting the maintenance plan items corresponding to the on-off action: when the on-off action is caused by maintenance, outputting the maintenance item. The technical scheme provides support for the scheduling personnel to identify reasons of the on-off action and make a timely and correct decision.
