International ClassB66B 001/40Foreign Application Priority Data1998-02-02 EPAbstractA method and an apparatus for controlling an elevator is equipped with a deck-distance drive machine which by reference to positional information adjusts the distances between the individual cars in a common car sling in such a way that each car can stop at the corresponding floor accurately, i.e. without forming a step. Measured values of floor position are stored in memories and periodically updated so as to detect any changes such as, for example, building settlement. Based on this data the necessary deck-distances are calculated which are necessary for all the cars to stop without any of them forming a step. Furthermore, the method and the device can be correspondingly extended for a multi-decker elevator and for any type of control (conventional control, destination call control, etc.). | |
