CONTROL SYSTEM FOR AN ELEVATOR SYSTEM, ELEVATOR SYSTEM AND METHOD OF OPERATING AN ELEVATOR SYSTEM

摘要

A control system for an elevator system may comprise elevator cars and an elevator control for assigning elevator cars to destination calls. In a first mode of operation, the elevator control may be adapted to determine and assign an elevator car to transport a passenger based on at least one elevator car determination criterion. The elevator control may wait to provide information identifying the elevator car assigned to the passenger until the assigned elevator car approaches or arrives at a floor on which the passenger is located. Waiting to provide such information permits the elevator control to modify which elevator car ultimately transports the passenger based on intervening factors such as a door being held on an elevator car that was initially assigned to transport the passenger. In a second mode of operation, the passenger may be provided with the information that identifies the assigned elevator car immediately after the destination call is placed. In a third mode of operation, up/down calls may be placed.”
