Embodiment 1

[0038] Figure 1 to Figure 8 It is the first embodiment of the optimal elevator group management control device of the present invention.

[0039] figure 1 A block diagram showing the structure of the elevator group management control device, 1 is a building with n groups of elevators with the upper car and the lower car as a group, and 1S is the lift shaft for accommodating n groups of elevators. The elevator shafts 1S1 to the nth group are composed of elevator shafts 1Sn.

[0040] 5U1 is the upper car arranged in the elevator shaft 1S1 for the first group, 5D1 is the lower car arranged under the upper car 5U1, 6U1 is the counterweight of the upper car 5U1, and 6D1 is the lower car 5D1 counterweight. 7U1 is a hoist for raising and lowering the upper car 5U1, and 7D1 is a hoist for raising and lowering the lower car 5D1, which can independently raise and lower the upper car 5U1 and the lower car 5D1. 8U1 is the car operating panel of the upper car 5U1, and 8D1 is the car o...

Embodiment 2

[0119] This second embodiment is formed by adding the shared zone CZ of the first embodiment to the lower car priority zone DPZ. Therefore, it is an embodiment suitable for buildings where the equipment floor and the like are placed between the lower car priority zone DPZ and the upper car priority zone UPZ, and there is almost no traffic between the two zones.

[0120] Figure 9 (a) ~ (e) to Figure 11 The optimal elevator group supervisory control device according to Embodiment 2 of the present invention is shown.

[0121] directly inherited figure 1 The structure of the group management control device of the elevator shown and figure 2 The control circuit of the elevator group management control device shown.

[0122] Fig. 9 (a) - (e) are explanatory diagrams showing the actions of the upper car 5U and the lower car 5D, and are obtained by adding the shared area CZ of Fig. 4 (a) to (d) to the lower car priority area DPZ. into. Therefore, except that the ascending hall ...

Abstract

In an apparatus for elevator group control which performs group management of a set of elevators, the set consisting of an upper car and a lower car which are disposed in a vertical relation within one elevator shaft and which ascend and descend independently, the floors are classified so that a floor communicating with an entrance of a building is classified as a main floor for the lower car, a floor communicating with an entrance of the building above the main floor for the lower car is classified as a main floor for the upper car, a lower-floor portion of the shaft is classified as a lower-car priority zone, an upper-floor is classified as an upper-car priority zone, and an intermediate-floor portion is classified as a common-use zone of the upper car and the lower car. A hall call is assigned to the upper car or the lower car according to the classification to which the hall in question belongs. In each of the priority zones, the upper car or the lower car is preferentially brought into service. In the common-use zone, after the existence or nonexistence of interference with a counterpart car is determined, the upper car or the lower car is caused 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 and is caused to retreat to an escape floor.

Description

technical field [0001] The present invention relates to group management and control of one or more groups of elevators, which are arranged up and down in an elevator shaft and are independently lifted and lowered by an upper car and a lower car, so that the cars do not interfere with each other device. Background technique [0002] In traditional elevators, each elevator is usually provided with an elevator shaft, and one elevator shaft accommodates one car. Therefore, in the case of installing a plurality of elevators, elevator shafts corresponding to the number of elevators will be arranged in parallel, so that the cars can be freely moved up and down without interference. In such a setting, multiple elevator groups are managed and controlled to improve transportation efficiency. [0003] However, if an elevator shaft is provided for each car, there is a problem that the proportion of the area occupied by the elevator shaft in the floor area of ​​the building is too lar...
