Abstract

An elevator monitoring system, comprising: one or more sensors; a controller arranged to: acquire sensor data from the one or more sensors; analyse the sensor data to identify a first event and a second event, the first event corresponding to an elevator door motion; categorize the first event based on the sensor data for the first event and the second event. Categorizing the elevator door motion is useful for determining characteristics relating to the health of the elevator door system. For example, the number of times that the elevator car door has opened is a useful indicator of elevator system health (which can be used to indicate a need for maintenance). Additionally or alternatively, the number of times that the elevator car door has undergone a reversal motion is a useful indicator of elevator system health. A reversal motion is a closing motion which commenced, but did not finish, resulting in a re-opening of the elevator door.
