Abstract

A sensor system (1) for an elevator assembly determines the alignment between the floor level of an elevator car (2) and the floor level (3) of a building when the car has come to a stop. The elevator assembly comprises an elevator shaft (4), means (6) for moving the elevator car in the shaft, a plurality of openings in the shaft corresponding to floors of the building and a control system (20) to cause the car to stop at a particular floor. The system (20) comprises sensor means (10, 13, 14) to detect the position of the elevator car (2), processing means (15) to calculate the alignment between the floor level of the elevator car (2) and the floor level (3 ) of the building when the elevator car stops at a floor, and storage means (19) for storing the data at least when it is determined that the alignment between the floor of the car and the floor level is outside predetermined tolerances.
