Abstract

L'invention concerne un procédé, un appareil, un dispositif et un support de diagnostic de défaillance d'ascenseur. Le procédé comprend les étapes suivantes : s'il est déterminé qu'une opération de freinage actuelle d'un frein d'ascenseur est déclenchée, obtenir le nombre actuel de fois où l'opération de freinage du frein d'ascenseur a été déclenchée ; et si le nombre actuel de moments déclenchés est supérieur à un nombre seuil prédéfini N de moments déclenchés, et que l'énergie de frein de freinage générée par l'opération de freinage actuelle satisfait à une condition de freinage anormale déterminée en fonction de l'énergie de frein de freinage générée pendant les première à nième opérations de freinage, déterminer qu'un ascenseur installé avec le frein d'ascenseur se déplace de manière anormale. Les présents procédé, appareil, dispositif et support de diagnostic de défaillance d'ascenseur peuvent améliorer le degré de précision avec lequel des défaillances d'ascenseur sont déterminées.
