Elevator system configured to decentralize allocation of hall calls

摘要

A method for allocating elevators in an elevator system, the elevator system including a group control system responsive to hall calls received from call input devices, and elevator-specific elevator controllers configured to control elevators based on commands issued by the group control system, wherein the method including generating a number of route alternatives based on calls active; calculating, by the elevator controllers, elevator-specific cost terms associated with the route alternatives; transmitting, by the elevator controllers, the cost terms to the group control system; and allocating, by the group control system, the hall calls to the elevators according to the route alternative giving the lowest allocation cost.

1. A method for allocating elevators by at least one group control system in an elevator system, the elevator system including the at least one group control system and elevator-specific elevator controllers configured to control elevators based on commands issued by the at least one group control system, wherein the method comprises:
registering hall calls entered using the call input devices; generating a number of route alternatives based on active ones of the hall calls; receiving elevator specific cost terms from the elevator controllers, the elevator-specific cost terms being associated with the route alternatives; and allocating the hall calls to the elevators according to the route alternative giving the lowest allocation cost by,
determining which ones of the hall calls are traditional calls received from an up/down input device and which ones of the hall calls are destination calls received from a destination call terminal,allocating the destination calls based on the route alternative giving the lowest allocation cost without delaying the allocating of the destination calls, anddelaying allocating the traditional calls by instructing the elevator controllers to recalculate the cost terms associated with the traditional calls as the elevator giving the lowest allocation cost approaches a call input floor associated with the up/down input device.
