Patent ID: 7735611

Claim:
Method for identifying an incoming peak traffic condition in an elevator system, the method comprising the steps of: monitoring in real-time peak hour identification of the elevator system the number of car calls and the car load of an elevator taking in passengers in a lobby area; determining a car load threshold value, on the basis of which an elevator is identified as a peak elevator if the car load exceeds the car load threshold value; defining a threshold value of car calls, on the basis of which a peak elevator is identified if the number of car calls to floors outside a lobby area exceeds the threshold value of car calls; collecting statistical data regarding the numbers of passengers arriving to a floor in the elevator system and those leaving the floor during predetermined time windows; and selecting the prevailing traffic type as an incoming peak traffic condition if at least one peak elevator has been detected and the collected statistical data for the current time window indicates an incoming peak traffic condition.
