ABSTRACT:
An identification system for a lift installation in which a lift user carries with him an information transmitter. The information transmitter communicates individual data, for example the weight of the lift user, to a recognition device, which files the data in a data bank. Lift users without information transmitters, so-called unauthorized travellers, are detected with the aid of a load-measuring device. A comparator compares the weight in a lift cage with the weight identified by means of the information transmitter to verify the identity of the lift user as the user to whom the information transmitter was assigned. In the case of agreement, a release signal issued to a lift control, which dispatches or otherwise permits operation of the lift cage.
