ELEVATOR SYSTEM AND METHOD FOR LOCATING SERVING ELEVATORS IN RESPONSE TO EACH PROMPTED CAR CALL

摘要

A method for automatically prompting a car call in an elevator system, determining the number of passengers, allocating the elevator car alternatives as serving elevator cars (110) for the passengers. The elevator system including a door sensing device (122) and a surveillance device (131) for monitoring passenger actions, thereby defining the starting point and the final point of a passenger's traveling path. The method also includes calculating a passenger's traveling time period, thereby yielding a time forecast of the passenger's arrival time at a waiting lobby (108). A cost function containing at least one landing time factor is determined for calculating the cost value of each elevator car alternative. The alternative that gives the lowest cost value is allocated as the serving elevator car for the passenger. The elevator system also receives information from external devices via one or more communicative linkages for system operation.
