Abstract

Device for the control of an elevator, with a drive regulated according to the number of revolutions, a series of floor switches assigned to the various floors that, when passing the elevator car, each generate the corresponding floor signal, and a command apparatus consisting of a call handling device equipped with call memories assigned to the various floors, and a step-by-step connection mechanism equipped with position units assigned to the various floors, and which generates a stop signal when the step-by-step connection mechanism reaches a floor position for which a call is stored in the call handling device, a voltage of increasing nominal value for acceleration being supplied to the drive, from a nominal transmitting apparatus, and a constant for running at maximum speed, and forming from the start-up of the elevator, depending on the path traveled or, at each moment of the maximum admissible speed for the service of the next floor to be serviced, the corresponding braking nominal value voltages that, when presenting a stop signal, are imposed on the drive as nominal value voltage, while the Step-by-step connection mechanism advances, by means of a connection step signal, one step each time the elevator starts and, as long as there is no stop signal, each time there is a case of equality or a predetermined difference between the braking nominal value voltage and a voltage corresponding to the momentary speed of the elevator, characterized in that, for the formation of the braking nominal value voltage, a predetermined unit of paths is provided that forms voltages corresponding to the distances between floors and that during the operation of the elevator car, connects these voltages to their output step by step in the order of succession of the the floors when the connection signal is presented, and disconnects them from their output step by step when the floor signal is presented, the output of said unit being, together with the output of an integrator that integrates the voltage of a device that transmits nominal value and that, at the beginning of the march and when a floor signal is presented, it returns to zero, connected to the input of an adder that determines the difference in the starting magnitudes of the route setting unit and the integrator, and that It is mounted in front of a root former.
