Abstract

L'invention concerne un système de surveillance à distance d'ascenseur qui est pourvu : d'un appareil de commande d'ascenseur (200) pour commander l'entraînement d'un ascenseur (20) ; d'un appareil d'actionnement à distance (300) qui communique avec l'appareil de commande d'ascenseur (200) et qui amène l'ascenseur (20) à effectuer une opération de réponse à un mauvais fonctionnement . Lorsque l'appareil de commande d'ascenseur (200) détecte le mauvais fonctionnement d'un dispositif inclus dans l'ascenseur (20), l'appareil de commande d'ascenseur (200) émet un signal de mauvais fonctionnement contenant un code de mauvais fonctionnement permettant d'identifier le dispositif fonctionnant mal. Si la cause du mauvais fonctionnement du dispositif fonctionnant mal est un mauvais fonctionnement de signal de MARCHE dans lequel un signal de MARCHE est sorti continuellement, l'appareil d'actionnement à distance (300) transmet une instruction de coupure d'énergie au dispositif fonctionnant mal. En outre, l'appareil d'actionnement à distance (300) surveille le signal entré dans l'appareil de commande d'ascenseur (200) provenant du dispositif fonctionnant mal après la transmission de la commande de coupure d'énergie, et lorsqu'un signal de MARCHE est détecté, il est déterminé qu'une borne de connexion (420), qui s'étend à partir du dispositif fonctionnant mal et qui est connectée à l'appareil de commande d'ascenseur (200), et une borne d'entrée (418) de l'appareil de commande d'ascenseur (200), qui est la destination de connexion de la borne de connexion (420), ont une mauvaise connexion. Par conséquent, lorsqu'un mauvais fonctionnement de signal de MARCHE s'est produit, il est possible de déterminer si la cause de ce dernier est le mauvais fonctionnement d'un dispositif qui est la source de la sortie de signal, ou une mauvaise connexion entre la borne de connexion (420) et la borne d'entrée (418).
