Problems solved by technology

However, since the amount of change in energy when the occupancy rate of the elevator car assigned to the hall call increases is different between the elevator power operation and the elevator regenerative operation, even if the weight of the counterweight and the weight of the elevator car are close to a balanced state, there is The elevator car with a large energy increase may be used for distribution, and there is a problem of little energy saving effect

[0050] In this embodiment, an example of an elevator group management system capable of reducing power consumption will be described.

[0051] figure 1 It is a control block diagram of the entire elevator group management system of this embodiment. The individual elevator control devices 21A-21C of each elevator control the operation of K elevator cars 22A-22C, and the group management control section 1 performs unified control of each individual elevator control device.

[0052] The hall call signals input by the hall call (elevator hall call) registration devices 3A and 3B installed on each floor of the building are also transmitted to the group management control section 1. Here, the hall call registration devices 3A and 3B are devices that call elevators using, for example, up and down buttons.

[0053] Each elevator car 22A-22C has destination floor registration apparatus 23A-23C in a car, and load sensor 24A-24C in a car, respectively. In addition, it detects the information ...

Abstract

If an elevator lift car whose balance weight and the weight of a lift car are close to a balance state is set as easier assignment, energy variations resulted from increase of occupancy rate of the elevator lift car due to an assigned hall call are different in power running and regeneration work, so that the elevator lift car with large energy increment is used for assignment, thus leading to a problem that an energy-saving effect is small. The invention provides an elevator group management system which assigns the elevator in response to the hall call from a plurality of elevators. In relative to the occupancy rate of a specified lift car, occupancy number in the specified lift car or load capacity of the specified lift car of each elevator among the plurality of elevators becoming boundary of converting the power running and the regeneration work, the elevator having a predicated occupancy rate, a predicated number or a predicated load value in the lift car after passengers by the hall call is smaller than the specified occupancy rate, the specified in-car number or the specified load capacity and having values close to the specified values is set as the easier assignment.

Description

Technical field [0001] The invention relates to an elevator group management system, in particular to an elevator group management system that distributes the hall calls from multiple elevator cars when an elevator call occurs in the elevator hall. Background technique [0002] The elevator group management system manages multiple elevator cars as an elevator group, which can provide passengers with more efficient operation services. Specifically, the elevator group management system manages multiple elevator cars (for example, 3 to 8 elevator cars) as an elevator group, and a hall call occurs on a certain floor (a call to an elevator in the elevator hall) At this time, the elevator group management system performs allocation control, selects an appropriate elevator car from the elevator group, and allocates the hall call to the selected elevator car. [0003] As a prior art in this technical field, Japanese Patent Application Laid-Open No. 9-227033 (Patent Document 1) can be cite...
