摘要:
A double-decker elevator includes a winch, an upper car, a lower car, a car support frame supporting the upper and lower car, a car space adjusting device capable of adjusting the space between the upper and lower car, and an emergency operation controller. When the car space adjusting device is unable to operate normally, the emergency operation controller operates the winch to move the car support frame such that the upper and lower car are located sequentially at positions corresponding to adjacent floors, respectively.

In an apparatus for elevator group control which performs group management of a set of elevators, the set consisting of an upper car (5U) and a lower car (5D) which are disposed in a vertical relation within one elevator shaft (1S) and which ascend and descend independently, the floors are classified in such a manner that a floor communicating with an entrance of a building (1) is classified as a main floor for the lower car (1F), a floor communicating with an entrance of the building above this main floor for the lower car (1F) is classified as a main floor for the upper car (2F), a lower-floor portion of the shaft (1S) is classified as a lower-car priority zone (DPZ), an upper-floor portion is classified as an upper-car priority zone (UPZ) and an intermediate-floor portion is classified as a common-use zone (CZ) of the upper car (5U) and the lower car (5D). The hall call is assigned to the upper car (5U) or the lower car (5D) according to the above-described classification to which the hall in question belongs. In each of the priority zones (UPZ or DPZ), the upper car (5U) or the lower car (5D) is preferentially brought into service. In the common-use zone (CZ), after the existence or nonexistence of interference with a counterpart car is judged the upper car or the lower car is cause to make an entry and is brought into service and after a response the upper car or the lower car is caused to escape from the common-use zone (CZ) and is caused to be in retreat on the escape floor.

A double-deck elevator includes a winch (6), an upper car (2), a lower car (3), a car support frame 1 supporting the upper and the lower car (2, 3), a car space adjusting device (4) capable of adjusting the space between the upper and the lower car (2, 3), and an emergency operation controller (12). When the car space adjusting device (4) is unable to operate normally, the emergency operation controller (12) operates the winch (6) to move the car support frame (1) such that the upper and the lower car (2, 3) are located sequentially at positions corresponding to adjacent floors, respectively.
摘要:
A control device for a double-deck elevator system having an upper deck and a lower deck, includes a group control device for assigning the upper and lower decks to respond to car calls from the upper and lower decks and boarding hall calls from a plurality of floors. The control device further includes an assignment control device for determining whether a plurality of the car calls and boarding hall calls can be responded to simultaneously and for directing said group control device to reassign the upper and lower decks to respond to the plurality of car calls and boarding hall calls simultaneously.
摘要:
An elevator system having cars in service at top and bottom in a single shaft with efficient group control. The elevator system is provided with a shaft assignment finalizing unit for selecting a shaft and a car to be assigned to a new call, and a reassigning unit for reassigning a car as necessary when a new call occurs after assignment is performed. After tentative assignment is finalized, if a new call is generated before a time for finalizing a stop of a tentatively assigned car is reached, then the tentative assignment is reviewed. If it is determined that reassigning of cars is necessary for a call, then the reassigning unit changes car assignment to the call. Assignment of a car is finalized by the car assignment finalizing unit, and information regarding a final decision is displayed by a display controller.
摘要:
The hoist control device controls the hoist in such a manner that once the speed change of the cage frame has accelerated at a fixed acceleration, constant speed is maintained, after which it decelerates at a fixed deceleration and stops. Meanwhile, the cage chamber position control device controls the cage chamber drive device in such a manner that once the speed change of the cage chamber driven by the cage chamber drive device has accelerated at a fixed acceleration, constant speed is maintained, after which it decelerates at a fixed deceleration and stops.
摘要:
Genetic procedure for the allocation of calls issued via the landing call devices of elevators included in a multi-deck elevator group, in which procedure a multi-deck elevator model is formed in which the limitations of and rules of behaviour for each elevator in the multideck elevator group and each car of each elevator are defined; a plurality of allocation options, i.e. chromosomes are formed, each of which contains a car data item and an elevator direction data item for each active landing call, and these data, i.e. genes, together define a car to serve each landing call as well as a collective control direction for the elevator; for each chromosome, a fitness function value is determined; one or more of the chromosomes are selected and altered in respect of at least one gene; fitness function values are determined for the new chromosomes; the process of altering the chromosomes, selecting chromosomes and determining fitness functions is continued until a termination criterion is met and, based on the fitness function values, the most suitable chromosome is selected and the calls are allocated to the elevators and cars in the elevator group in accordance with this solution.
摘要:
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. The cost function may include the estimated time of arrival to the destination floor. Alternatively, the cost function may also include the estimated time of arrival to the furthest call floor.

An elevator system having a double-deck car (24) normally responds to unanswered up hall calls from intermediate floors with the upper deck (26), except, under one or more conditions, whereby a subsequent stop may be avoided, its lower deck (28) is utilized.
