Abstract
The present invention relates to the tracking of a maintenance trajectory in an elevator system. An apparatus provided by the present invention for tracking a maintenance trajectory in an elevator system is configured to generate, based on acquired relative height information of a maintenance worker entity in a lifting passage corresponding to the elevator system, maintenance trajectory information corresponding to the maintenance worker entity. The present invention makes it easy to implement monitoring or management of each maintenance operation of each maintenance worker entity, and also makes it easy to judge the compliance status of the maintenance operation.
