Abstract: The invention relates to a procedure for controlling an elevator group consisting of double-deck elevators.

Abstract: A method for controlling an elevator group of double-deck elevators. Landing calls are allocated to the elevators and elevator decks in such a way that the passenger journey time is optimized. The method takes into account the current landing call time and the estimated time of arrival to the destination floor. The method minimizes passenger journey time by allocating the landing call to the deck that will cause the fewest additional stops to the elevator and least additional delay on the way to the passenger destination floor. In addition, the elevator estimated time of arrival to a destination floor is calculated separately for each deck, taking into account the stops already existing for the elevator and the additional stops caused by the selected landing call. Further the landing call is allocated to the deck for which the estimated time of arrival to the destination floor is least. In addition, the best deck for each landing call is selected by minimizing a cost function.

Abstract: An controlling apparatus for a double deck elevator is disclosed. An allocation control unit (5), when a predetermined specified floor is registered in an elevator hall call registering unit (4) in a double operation mode, makes both of upper and lower cages of each double deck elevator respond thereto. Each cage call registering unit (9) is capable of registering a cage call to both of the upper and lower cages in the double operation mode as far as the specified floor is concerned. An operation control unit (8) in each elevator controls operations of the upper and lower cages to respond to the elevator hall call to the specified floor which is allocated by the allocation control unit (5) and to a cage call to the specified floor which is registered in the cage call registering unit (9).

Abstract: A 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.).

Abstract: When a reference cage is designated at the time of determining the parameters which distinguish hall devices, reference cage determination device 1 determines as the reference cage the designated cage out of upper and lower cages, and the reference cage determined by the reference cage determination device is raised/lowered to and stopped at a designated terminal floor by reference cage travel device 2. Then, parameter determination device 3 determines parameters based on the floor at which the reference cage determined by reference cage determination device 1 has stopped, and parameter transmission device 4 transmits the parameters determined by parameter determination device 3 to the hall device of the floor at which the reference cage is positioned.By so doing, the setting of hall device parameters can be readily performed at the time of installation or the time of maintenance/replacement of double-deck elevators which do not possess projecting floors.
