Abstract

Des systèmes classiques de commande d'ascenseur ont pour fonction d'arrêter un ascenseur à un étage lors de la détection d'un enfant en bas âge. Cependant, même lorsque l'enfant en bas âge monte seul dans l'ascenseur, l'ascenseur démarre l'opération de fermeture de porte et se déplace vers le prochain étage de destination. Ainsi, il existe un problème en ce que l'accompagnateur de l'enfant en bas âge reste sur le palier et ne peut pas monter dans l'ascenseur avec l'enfant en bas âge. Ce système de commande d'ascenseur est caractérisé en ce qu'il consiste à déterminer si oui ou non un utilisateur qui entre dans une cabine est une personne devant être accompagnée et à utiliser le degré ou la proximité entre la personne devant être accompagnée et un autre utilisateur pour déterminer si oui ou non l'autre utilisateur est un accompagnateur.
