Title: ELEVATOR GROUP CONTROL SYSTEM
Abstract:
The purpose of the present invention is to ensure, at times of congestion when users are arriving successively at an elevator landing, that elevator cars standing by at the elevator landing on that floor are controlled effectively, thereby enabling the users to efficiently board the elevator cars without wasting time and improving the overall transport capacities of group-control elevators. To achieve the foregoing, this elevator group control system controls the operation of multiple elevator cars, wherein the system comprises: a means for detecting the number of users present at an elevator landing on a prescribed floor; a means for detecting the number of riders inside elevator cars that are stopped with open doors at this prescribed floor; a means for calculating, on the basis of such number of users at the landing and such number of riders inside the cars, the number of elevator cars to be stopped with closed doors at the prescribed floor; and a means for opening the doors of any elevator cars that are stopped with closed doors at this prescribed floor.
