Problems solved by technology

[0006] The purpose of the invention is to provide a new elevator group control method, change the control scheduling method in the prior art with the "leader" as the main body, and realize the peer-to-peer control of the elevators, thereby solving the "leader" optimization solution calculation work To solve the problem of heavy traffic and realize the optimal allocation of outbound calls

Embodiment 1

[0022] Embodiment one: see figure 1 As shown, an elevator group control method, the elevator group is composed of at least 2 elevators, the hall call request is sent by the call button set on the hall call board of each floor, the main control board, car board and hall call board of the same elevator The boards are connected by the first communication circuit, and the main control board of each elevator is provided with a storage area for storing all unserved outbound call requests in the entire group control system, forming a group control outbound call shared pool, and all elevators The control board is connected via the second communication circuit.

[0023] In this embodiment, the first communication circuit is CAN1 communication, the second communication circuit is CAN2 communication, each elevator is single elevator 1, single elevator 2, ..., single elevator n, each elevator is respectively equipped with a main control board, car board, and hall call boards installed on...

Abstract

The invention discloses an elevator group control method. A storage area used for storing all outbound requests which are not served in a whole group control system is arranged in a main control panel of each elevator to form a group control outbound shared pool, and the main control panels of all the elevators are connected through a second communication circuit. The elevator group control method includes the following steps: (1) building an elevator group; (2) the outbound service requests sent by outbound boards are added to the group control outbound shared pool of each elevator after being received; (3) polling group control is carried out by the main control panels of the elevators on outbound service request queues in the outbound shared pools in real time, and the main control panels of the elevators send group control outbound service request instructions; and (4) loopback group control outbound service request response instructions of other elevators are collected, whether the outbound service requests succeed is determined, and if the outbound service requests succeed, the group control outbound service requests are completed. According to the elevator group control method, the concept of a 'leader' is abandoned, the concept of the 'group control outbound shared pools' is introduced, all the elevators compete freely to acquire the outbound requests, task load statistics are balanced, and the optimal outbound allocation is achieved.

Description

technical field [0001] The invention relates to a control method, in particular to a method for controlling and dispatching an elevator group composed of multiple elevators. Background technique [0002] With the increase of building height and scale expansion, many elevators are installed in high-rise buildings, and higher requirements are put forward for the control technology of elevators. Generally speaking, the current elevator control system is no longer limited to the traditional single-elevator control, but has gradually developed to control and dispatch multiple elevators in the entire building as a whole elevator group, that is, elevator group control . [0003] In the prior art, there are mainly two scheduling control modes of the elevator group control. One is centralized group control scheduling with group controller; the other is master-slave group control scheduling without group controller. Regardless of the group controller mode or the master-slave mode, ...
