S103: Match the content of the task list with the information of the maintenance personnel and assign tasks.

Specifically, the device will continue to generate signals during operation, and each signal will appear and last for a period of time according to the predetermined time point. When a signal appears at an incorrect time point or the duration of occurrence deviates from the standard value defined in the system , Calculate the offset rate of the matching rate. Matching offset rate = duration offset rate + action number offset rate. Duration deviation rate = the absolute value of the difference between the actual duration and the standard duration divided by the standard duration multiplied by a percentage, and the number of actions deviation rate = the number of actions with an error sequence divided by the total number of actions multiplied by a percentage Percent, the maintenance personnel's information includes the maintenance personnel's skill base, work experience, and the equipment field that they are good at.
