Group management system of elevator

Abstract

The invention provides an elevator group management system; the elevator group management system is able to well control the balance degree of the aspect of restraining each elevator lobby calling by continuously passing through the car and the aspect of reducing the time of the whole building waiting for the elevator lobby calling; when ensures to dispatch the elevator car to the new elevator lobby calling, forecasting whether the car pass through the floor having elevator lobby calling (except from full commission), according to the forecasted result, deciding the elevator car dispatched to the elevator lobby calling. So, the combination of dispatching the elevator car and passing through the car is considered, and the pass of the car is reasonably restrained according to the condition of passing.

Description

technical field [0001] The present invention relates to a group management system for comprehensively managing the operation of a plurality of elevators, and to a system for allocating the most appropriate elevator for the registered elevator hall calls in consideration of serviceability to users Elevator group management system. Background technique [0002] The elevator group management system treats multiple cars as a group, so as to provide users with more efficient operation services. Specifically, a plurality of cars (usually three to eight) are managed as a group, and when an elevator hall call occurs on a certain floor, the following control is implemented, namely: select a most suitable car from the group. car and assigns that car to the preceding elevator hall call. [0003] In existing group management systems, distribution control is basically performed based on an evaluation function based on predicted waiting time. This is to calculate the predicted waiting ...

Problems solved by technology

[0013] In the conventional technologies listed above, it is difficult to achieve a well-balanced control of both the suppression of car passage for each elevator hall call and the reduction of the average waiting time for elevator hall calls in the entire building.

[0014] First of all, in the method disclosed in Japanese Invention Patent Publication No. 63-23108, when it is judged that there is a car passing through, on the basis of disregarding the allocation situation, it issues a restriction command to restrict the passing of the car , and the car is stopped. In this way, although the car can be prevented from becoming a passing car, it is difficult to take into account the waiting time of the elevator hall call as a whole.

[0015] Secondly, in the Japanese Invention Patent Publication No. 2-33629 and the Japanese Invention Patent Publication No. 2-38150, there is no consideration for reducing the passing car of the non-full load elevator
