ELEVATOR ARRANGEMENT

摘要

The present invention concerns a method and a system for transmitting call data in an elevator system. In an embodiment of the present invention, the call buttons located in the elevator car are connected serially via a bus i.e. cable to each other. Another possible embodiment is one in which the landing call buttons located in the elevator lobbies on different floors are connected serially along the same bus. In both embodiments, the bus is further connected at one end to a microprocessor, which takes care of the control of the elevators. The processor identifies the signals of different buttons on the basis of address data. In both example embodiments, it is also possible to connect to the bus special buttons, such as an alarm button, which are included in the control panel in the elevator car. In addition, it is also possible to connect to the bus the floor nuuber displays and direction arrow displays in the elevator car and in the elevator lobby. In the most extensive embodiment example of the present invention, the buttons, displays and special devices of all the elevators in the elevator system can be connected to the same bus.
