Abstract

La présente invention se rapporte à un ascenseur pouvant corriger de façon appropriée des données de position obtenues par le biais d'une opération d'apprentissage, conformément aux conditions en cours de l'ascenseur par un simple traitement sans interruption du fonctionnement de l'ascenseur. Une valeur de mesure d'impulsion obtenue lorsque la cabine de l'ascenseur passe d'un emplacement de référence prédéfini à chaque arrêt de montée à bord est mémorisée dans une unité de mémorisation en tant que données de position de l'arrêt de montée à bord au préalable, et le fonctionnement de la cabine en réponse à un appel est commandé sur la base des données de position dans l'unité de mémorisation. En outre, un calcul est effectué du pourcentage de changement entre une valeur de mesure d'impulsion obtenue lorsque la cabine s'est déplacée entre des arrêts de montée à bord prédéfinis en réponse à un appel et une valeur de mesure d'impulsion entre les arrêts de montée à bord prédéfinis calculée à partir des données de position dans l'unité de mémorisation, et sur la base du pourcentage de changement calculé, les données de position dans l'unité de mémorisation sont corrigées pour tous les arrêts de montée à bord de la cabine.
