ELEVATOR GROUP CONTROLLER, ELEVATOR GROUP, A METHOD FOR ALLOCATING CALLS IN AN ELEVATOR GROUP, AND APPLICATION EXECUTABLE IN A REMOTE SERVICE CENTRE OR IN THE ELEVATOR GROUP

摘要

The invention is aimed to improve control of wear and tear of the elevators in an elevator group comprising a plurality of elevators and at least one group control unit. The actual usage of each elevator is recorded, and the group control unit executes at least one allocation algorithm for selecting which elevator of the elevator group is used to serve a call. The allocation algorithm is configured to compare the actual usage of at least two elevators against respective target usages and to select the elevator having its actual usage most deviating from the target usage to serve an outstanding call. With the invention, the wear and tear of elevators may be balanced, or certain elevators may be set to reach the end of the maintenance period sooner.
