Abstract
A method and a device for monitoring characteristics of an elevator door motion procedure use a smart mobile device including multiple sensors. The method includes: (i) determining a time window, within which a door motion is assumed to occur, including a time interval enclosed by a start time limit and an end time limit and wherein at least one of the start time limit and the end time limit is determined based on first measurement values acquired by a first sensor in the smart mobile device; and (ii) detecting characteristics of the procedure based on second measurement values acquired during the time window by a second sensor in the smart mobile device. Using the method, door motion characteristics can be reliably monitored using a passenger's smart mobile phone while substantially limiting sensing and processing capacities required by the smart mobile phone as well as avoiding compromising passenger privacy requirements.
