Problems solved by technology

[0004] 1) The optimal elevator car allocation is made for the elevator hall calls that have occurred, but the impact of elevator hall calls that may occur in the future is not fully considered
[0005] 2) Since the elevator hall calls are assigned to each elevator car based on the predicted waiting time as the allocation index, the positional relationship between the elevator cars is not considered
However, for elevator cars with a running time of 90 seconds or more in a week, the allocation of new elevator calls is not suppressed, which may cause the running time of the week to become longer
[0030] In the prior art that selects the elevator car for distribution based on the deviation between the predicted arrival time of the distribution elevator car at a specific floor and the reference time, the object of its control is the difference between the predicted arrival time of the specific floor and the reference time. Deviation between reference times, so it may not be possible to guarantee a shorter cycle time for each elevator car
Moreover, because this control method does not take into account the time interval control of each elevator, it cannot be guaranteed that each elevator car is controlled to be close to the equal interval state by relying on this control method alone.

Embodiment Construction

[0068] Embodiments of the present invention will be described below with reference to the drawings.

[0069] Fig. 1 is an overall control block diagram of an elevator group management control system related to the first embodiment of the present invention. The operation of N elevator cars 22A-22C is controlled by the control devices 21A-21C of the elevators, and the control devices of the elevators are centrally controlled by the elevator group management control part 1.

[0070] In the elevator group management control section 1, the following processing is performed. First, the input information storage unit 2 stores the elevator call information from the arrival floor registration devices 31A and 31B installed in the elevator halls of each floor (hereinafter referred to as the hall) and the control devices 21A to 21C of each of the N elevators. Information. Among them, the arrival floor registration devices 31A, 31B are devices that allow passengers who plan to take the e...

Abstract

A kind of elevator group management control method is disclosed. That evaluating time interval of every elevator cage to control distribution of elevator cage may unnecessarily increase number of elevator calling stops and increase runtime in a week, so as to cause waiting time increased. Waiting time will not be increased and a more appropriate distribution of elevator cage will be achieved when carrying out distribution evaluation of newly elevator hall calling in the invention. It computes the first evaluation of waiting time evaluation of estimate, computes the second evaluation of time interval evaluation of estimate among adjacent elevators and computes the third evaluation of running time evaluation of estimate in a week of each elevator. Every evaluation of estimate of the first evaluation, the second evaluation and the third evaluation are weighted computed and evaluated according to visitors flowrate mode, then integrated evaluation is computed. The elevator allocated for elevator hall calling is decided according to the integrated evaluation.

Description

technical field [0001] The present invention relates to an elevator group management control method and an elevator group management control system, in particular to an elevator group management control method and an elevator group capable of evaluating to assign the most suitable elevator car to an elevator hall call that occurs Management control system. Background technique [0002] The elevator group management system manages multiple elevator cars as an elevator group, so as to provide users with efficient operation services. Specifically, multiple elevator cars (usually three to eight) are managed as an elevator group, and when an elevator hall call occurs on a certain floor, a most suitable elevator is selected from the group of elevator cars car and assigns the elevator hall call to that elevator car. [0003] In the traditional elevator group management system, the evaluation function is basically calculated according to the predicted waiting time, and then the di...
