Abstract

See full text

The invention relates to an elevator system for observing a misoperation. The elevator system comprises an observation unit and a processing unit. The observation unit is configured to obtain data representing movement of an elevator car during a predetermined time interval and transmit the obtained data to the processing unit. The processing unit is configured to receive and store the data representing the movement of the elevator car, generate at least one statistical parameter from the received data, compare the at least one generated statistical parameter to at least one previously stored statistical parameter of the corresponding time interval, and generate a signal indicating a misoperation in response to a detection that the at least one generated statistical parameter deviates from the corresponding previously stored statistical parameter over a predetermined limit. The invention also relates to a method for observing a misoperation.
