Problems solved by technology

However, in the group management control processing part of the group management system, the three double-deck elevators are recognized as six single-deck elevators, the target route is generated so that the six cars are kept at equal intervals, and the evaluation value calculation is performed thereafter, Therefore, there may be cases where optimal allocation processing cannot be performed

Embodiment 1

[0068] First, refer to Figure 1 to Figure 9 The group management system according to Embodiment 1 will be described. The group management system according to the first embodiment is characterized in that any one of the upper and lower connected cars is used as a reference car, and only the reference car is calculated for the path evaluation value, and for the other cars, the The path evaluation value is set to be the same as the path evaluation value of the reference car, and the car assigned to the hall call is selected on this basis.

[0069] Such as figure 1 As shown, the elevator group management system involved in Embodiment 1 is mainly composed of a group management control part 1, multiple (N) double-deck elevators (60, 61, 62), and upper cars (70, 71) that control double-deck elevators. , 72) the upper car control device (50, 51, 52), the lower car control device (40, 41, 42) that controls the lower car (80, 81, 82) of the double-deck elevator, and is installed on each ...

Embodiment 2

[0102] Below, refer to Picture 10 The group management system according to the second embodiment will be described. The group management system according to the second embodiment is characterized in that the reference car when the target route is generated is changed in accordance with each direction when the elevator is going to the hall call.

[0103] Each step from step ST201 to step ST206 is figure 2 Steps ST101 to ST106 in the operation flow of the group management system according to the first embodiment shown are the same. In addition, the respective steps from step ST214 to step ST217 are figure 2 Steps ST111 to ST114 in the operation flow of the group management system according to the first embodiment shown are the same. Therefore, in order to avoid repetitive description, the description of each step above is omitted.

[0104] The group management system according to the second embodiment is characterized in that steps ST207 to ST210 are added. That is, it is determi...

Embodiment 3

[0111] Below, refer to Figure 11 to Figure 18 The group management system according to the third embodiment will be described. The group management system according to the third embodiment is characterized in that when the path evaluation function is calculated on any one of the vertically connected cars, the stopping of the other car is also considered.

[0112] It can also be inferred from the description of Embodiment 1 that when the single-deck elevators are allocated and controlled based on the target route evaluation, figure 1 The predicted path processing part 14 in the illustrated operation management control system 10 generates a predicted path for one car for a new hall call. However, in a double-deck elevator, two cars work in a hoistway in a connected state. Therefore, when one of the cars receives a call (hall call and car call), the car assigned the registered call (own car) not only stops corresponding to the registered call, but also connects to the own car The...

Abstract

The invention provides an elevator group management system. Even a double-layer elevator, cages can be kept at an equal interval in time via distribution control. When a target path is generated, whether a target is a double-layer elevator (ST107) is firstly judged. If the target is judged as the double-layer elevator, ST108 is taken where whether it is calculation of a lower cage is judged. If it is the calculation of the lower cage, ST110 is taken where a path evaluation functional operation part 15 is used for carrying out calculation of a distribution evaluation value according path distance indexes. On the other hand, if it is the calculation of the upper cage, ST109 is taken where it is processed that the path evaluation value of the upper cage is set as the same as the path evaluation value, calculated in the ST110, of the lower cage.

Description

Technical field [0001] The present invention relates to an elevator group management system, in particular to an allocation control for allocating elevator cars (hereinafter referred to as "cars") to hall calls that have occurred. Background technique [0002] In the elevator group management system, multiple elevators are managed as an elevator group, so as to provide passengers with more effective operation services. Specifically, the following control is implemented: multiple elevators (usually 3 to 8) are managed as an elevator group, so that when a hall call occurs on a certain floor, one of the elevators in the elevator group is selected. The best car and assign the car to the hall call. [0003] When a hall call occurs on a certain floor, in order to minimize the waiting time of the target hall call, it is desirable to allocate a plurality of cars of the plurality of elevators at equal intervals in time. However, under traffic congestion conditions, the so-called "beading ...
