Definitions

  • the invention relates to a door control system for an elevator installation, an elevator installation with such a door control system and a method for operating such an elevator installation.
  • Such an elevator system has an elevator car that can be moved in an elevator shaft.
  • the elevator shaft connecting several floors of a building comprises several shaft doors arranged one above the other.
  • the elevator car includes a car door. By arranging the elevator car or the car door on one of these shaft doors, people or goods can be transported between these floors.
  • the opening or closing of such a car door or of such a shaft door, which may be coupled to the car door, is made possible by means of a door drive motor belonging to the elevator system.
  • the operation of the door drive motor is mainly controlled by means of control commands, which are generated or can be generated in an elevator controller of the elevator installation. These control commands are generated, among other things, as a function of the operating states of the elevator installation.
  • operating states are an elevator travel carried out in normal operating mode, maintenance mode or evacuation mode, or the elevator car is stopped at the floor or between two floors arranged directly one above the other.
  • such an elevator system has a higher-level elevator controller, which transmits control commands to the door drive motor based on the existing operating state.
  • a motor control unit is available to control the door drive motor, which feeds the door drive motor by means of a variable output voltage.
  • the motor control units of motors that are suitable as door drive motors are different, ie designed specifically for the motor.
  • the logic levels of different motors that are suitable as door drive motors are implemented differently.
  • adjustments must therefore be made on the elevator side (for example with regard to the logic level mentioned) so that the control commands can be implemented by the door drive motor.
  • the DE10102714A1 and the DE 102014212553 B3 include, for example, module-based concepts for engine control units. Such adjustments on the elevator side, in particular adjustments to the elevator control, are time-consuming. For example, additional wiring or engine-specific adapters are required.

  • the door drive motor is suitable for opening and closing door leaves. That means equivalently that the door drive motor is suitable for opening or closing an elevator door of the elevator installation.
  • the invention is based on the knowledge that a large number of versions of elevator installations are equipped with the same elevator control. Due to motor-specific requirements of the motor selected as the door drive motor, adjustments to the elevator control or the door control system are necessary with regard to the control signal.
  • a memory unit belonging to a motor adjustment unit was therefore implemented, by means of which the at least one configuration instruction of a, preferably at least two motors/motors suitable as a door drive motor can be stored and can thus be selected or activated simply after the associated motor has been connected to the elevator control by means of the switching unit.

  • the signal representing a control command transmitted from the elevator control to the motor adaptation unit can be adapted and consequently transmitted to the motor control unit, so that the action of the door drive motor that corresponds to the control command can be triggered.
  • the selection of such a control configuration instruction which can be selected by means of the switching unit, can accordingly bring about a change in the logic functions implemented in an integrated circuit. For this purpose, switches within the integrated circuit can be switched depending on the configuration instruction selected by means of the switching unit.
