Abstract

L'invention concerne un système de fonctionnement contrôlé pour un ascenseur, pouvant effectuer une opération de sauvetage du nombre maximum de passagers d'une cabine, tout en assurant la sécurité des passagers lorsqu'un tremblement de terre et une coupure électrique surviennent simultanément. Le système de fonctionnement contrôlé, doté d'un capteur sismique et d'une alimentation électrique d'urgence, comprend un moyen de contrôle de l'alimentation électrique d'urgence qui contrôle l'état de ladite alimentation électrique d'urgence et un système de prédiction de la consommation électrique qui prédit l'énergie électrique à consommer pour permettre à la cabine de l'ascenseur d'aller jusqu'à l'étage le plus proche. Quand la survenue d'un tremblement de terre est détectée par le capteur sismique, auquel cas la cabine s'arrête et du courant est fourni simultanément par l'alimentation électrique d'urgence, le sens de parcours de la cabine est correctement déterminé sur la base des informations contrôlées obtenues par le moyen de contrôle de l'alimentation électrique d'urgence et du résultat de la prédiction obtenu par le moyen de prédiction de la consommation électrique.
