Abstract

L'invention concerne un système d'ascenseur susceptible de supprimer une fausse détection d'un ascenseur se déplaçant avec une porte de cabine ouverte. Le système d'ascenseur comprend : un détecteur de position de cabine d'ascenseur qui détecte la position d'une cabine d'ascenseur ; un détecteur de porte ouverte qui détecte lorsque la porte de l'ascenseur est ouverte ; et un dispositif de protection de déplacement porte ouverte qui surveille la vitesse de la cabine d'ascenseur sur base d'une plage de mouvement admissible définie pour la cabine par rapport au sol d'un étage pour lequel une plage différente est définie pour le cas où la cabine commence à monter lorsque la porte est ouverte à l'étage où la cabine est arrêtée et pour le cas où la cabine commence à descendre lorsque la porte est ouverte à l'étage où la cabine est arrêtée.
