Title
(EN) ELEVATOR SYSTEM
(FR) SYSTEME D'ASCENSEURS
Abstract
(EN) The present invention discloses a method for optimal routing of the elevators in an elevator system in a situation where the supply power received by the system is limited e.g. due to emergency power operation. In the invention, routes are optimized by using a cost function to which has been added a term containing the summed instantaneous power consumed. Power consumption is monitored in real time, and the elevators need a start permission from the control system. A route alternative that exceeds the power limit is penalized in the cost function by a so-called penal term. With the elevator routing obtained as a result, the instantaneous power consumed by the system remains continuously below the set power limit. Some call can thus be postponed to be served later. By the method of the invention, the number of elevators serving passengers in an emergency power situation can be varied dynamically .
(FR) La présente invention concerne un procédé d'ordonnancement optimal des ascenseurs faisant partie d'un système d'ascenseurs dans une situation dans laquelle la puissance d'alimentation reçue par le système est limitée, par exemple, en raison d'un fonctionnement avec du courant de secours. Dans cette invention, les trajets sont optimisés au moyen d'une fonction de coût à laquelle a été ajouté un terme contenant la puissance instantanée totale consommée. La consommation d'énergie est surveillée en temps réel et les ascenseurs ont besoin d'une permission de départ émanant du système de commande. Un trajet de remplacement dépassant la limite de puissance est pénalisé dans la fonction de coût par un terme dit terme de pénalité. Avec le résultat du trajet d'ascenseur obtenu, la puissance instantanée consommée par le système reste inférieure, en continu, à la limite de puissance établie. Certaines demandes peuvent ainsi être reportées pour être traitées un peu plus tard. Le procédé de cette invention permet de faire varier de manière dynamique, le nombre d'ascenseurs desservant les utilisateurs dans une situation de courant de secours.
