Equipment monitoring events and maintenance work orders respectively describe the occurrence and handling process of exceptions. Data recovery represents the reconnection of the collection, but it cannot automatically prove that the on-site problem has been solved. The inspection results of the responsible position need to be kept separately.

Status source

First confirm whether the status comes from the device interface, manual registration or business system. Different sources require different verification methods. The platform should display the time of the last update to avoid continually displaying old status as currently normal.

Task linkage

After discovering an abnormality, you can create an inspection task and associate it with the device instead of just issuing a notification. Responsible personnel, processing steps and result explanations form a closed loop for exceptions, reminding that the quantity itself has no management value.

Historical background

Keep equipment maintenance, shutdown and replacement records to facilitate explanation of data changes. The system provides management tools and should not automatically make unverified maintenance judgments based on a single signal.

Scenario verification

After the abnormal equipment is restored, whether the original work order continues to be checked and whether the relevant status is updated needs to be determined according to the actual maintenance process. Restoring collection is just a technical fact and does not mean that the maintenance problem has been confirmed and resolved by the person responsible.

Specific verification method

Trigger an equipment exception, check the associated work order and the responsible position; check that the work order will not lose the original opinion after resuming collection; similar events occur continuously, verify the merging rules; after the maintenance personnel confirm the completion, the corresponding processing time of the event and work order can be found.

Monitoring is responsible for providing clues, and work orders are responsible for recording and handling. The two types of records remain associated, so exception recovery and maintenance confirmation will not be mixed into an unexplainable state.
