Abstract

L'invention concerne un dispositif d'ascenseur dans lequel une force de freinage à appliquer à une cabine d'ascenseur est générée lorsque la fourniture d'un courant électrique à une bobine de frein d'un dispositif de freinage est interrompue et que la génération de la force de freinage appliquée à la cabine d'ascenseur est arrêtée lorsque le courant électrique est fourni à la bobine de frein. Un dispositif de commande de frein comprend des premiers moyens de commande de frein pour commander la force de freinage qui est appliquée à la cabine d'ascenseur en régulant la quantité de courant électrique qui est fournie à la bobine de frein, et comprend également des deuxièmes moyens de commande de frein qui sont capables d'interrompre de force la fourniture du courant électrique à la bobine de frein. Les deuxièmes moyens de commande de frein comprennent des moyens d'ordinateur pour déterminer individuellement, sur la base d'informations reçues en provenance de moyens de détecteur spécifiques, si oui ou non un ascenseur présente une anomalie et, lorsqu'il a été déterminé que l'ascenseur présente une anomalie, exécuter une commande pour interrompre la fourniture de courant électrique à la bobine de frein.
