1. System for controlling elevators in an elevator system, which elevator system comprises a number of elevators (1A . . . 1H), the system for controlling elevators comprises:

  • first planar sensors that operate capacitively (2, 2A . . . 2H), said first planar sensors being arranged in a waiting area of each elevator (1A . . . 1H) on a first floor, said first planar sensors (2, 2A . . . 2H) being fitted to provide information about the presence and number of passengers waiting to go either up or down for an elevator in the waiting area on the first floor;

    second planar sensors that operate capacitively arranged in a waiting area of each elevator on a second floor, said second planar sensors being fitted to provide information about the presence and number of passengers waiting to go either up or down for an elevator in the waiting area on the second floor;

    additional planar sensor means that operate capacitively arranged in a waiting area of each elevator on additional floors, said additional planar sensor means being fitted to provide information about the presence and number of passengers waiting to go either up or down for an elevator in the waiting area on the additional floors; and

    control means for controlling the elevators, said control means being fitted to receive information from the first planar sensors (2, 2A . . . 2H) about the presence and number of passengers waiting to go either up or down for an elevator on the first floor, said control means being fitted to receive information from the second planar sensors about the presence and number of passengers waiting to go either up or down for an elevator on the second floor and said control means being fitted to receive information from the additional planar sensors about the presence and number of passengers waiting to go either up or down for an elevator on the additional floors and to control the movement of the elevators (1A . . . 1H) of the elevator system utilizing the information received from the first planar sensors (2, 2A . . . 2H), the second planar sensors and the additional planar sensors.
