    Abstract: A solution for estimating the number of persons entering or leaving an elevator car, wherein a stepwise change in passenger load is detected based on a passenger load signal relating to the elevator car, and the change in a passenger count is estimated based on passenger load change ranges depending on traffic intensity and the stepwise change in the passenger load.

    Abstract: An arrangement of counting passengers in an elevator using two separate counting mechanisms is disclosed. The elevator car typically has a curtain of light arranged to the door and a load weighing device arranged to measure the weight of the elevator car. From the information recorded by the curtain of light and the load weighing device, it is possible to count the number of passengers. The reliability of the counting results can be improved by processing the counting results for forming a combined counting result that provides a more reliable counting result when the independent counts deviate from each other.
