A SOLUTION FOR MANAGING USAGE DATA OF AN ELEVATOR SYSTEM OPERATING IN A CONSTRUCTION TIME USE MODE

摘要

The invention relates to a method for managing usage data of an elevator system (100) operating in a construction time use (CTU) mode. The method comprises: operating (210) the elevator system (100) in the CTU mode, obtaining (220) statistical usage data of the elevator system (100), comparing (230) the obtained statistical usage data to reference data, detecting (240) that the obtained statistical usage data deviates at least partly from the reference data, and generating (250) at least one control signal comprising an indication of the detected deviation to at least one operator system (114) in response to the detection of the deviation. The invention relates also to a computing unit (112) and an elevator system (100) for managing usage data of an elevator system (100).
