ABSTRACT:
A control circuit for allotting hall calls to elevator cars in an elevator car system, having a generator for generating a scanning signal consisting of scanning pulses. A hall call detector receives the scanning signal and generates a signal indicating the floor at which a hall call occurs. Elevator car detectors are provided, each of which receives the scanning signal and generates a signal indicating the position of the corresponding elevator cars. A memory circuit determines the serving areas of the respective elevator cars according to the signals from the elevator car detectors. An allotting circuit allots the signals from the hall call detector to the elevator car according to the area determined by the memory circuit.
