CA 2214382

An apparatus and method for providing an elevator door performance result of an elevator door in an elevator door system which normally operates sequentially from state-to-state in a closed loop sequential chain of normal operating states is disclosed. A plurality of parameter signals provided by the elevator door system is monitored by the apparatus. The apparatus comprises: a door state sequencer for providing a performance measure; a module for providing a reference measure and an acceptable range; and an abnormal detection module for analyzing the door performance measure.

Cette invention concerne un appareil et une méthode de contrôle du fonctionnement de portes d'ascenseur qui normalement passent successivement par une série séquentielle d'états en boucle fermée. L'appareil suit une pluralité de paramètres de fonctionnement desdites portes. Il comporte un contrôleur séquentiel d'état fournissant une mesure des paramètres de fonctionnement, un module générateur de paramètres de référence et de plage acceptable, et un module de détection des anomalies de fonctionnement par analyse comparative des paramètres réels et de consigne.
