Elevator group control operation system and method

Abstract

The invention discloses an elevator group control operation system and method. The elevator group control operation system comprises an elevator group, a group control cabinet for controlling operation of the elevator group and a standby power supply electrically connected with the elevator group; the elevator group comprises a plurality of elevators; a control operation module is arranged in each elevator; the control operation modules are in communication connection; each control operation module comprises a monitoring unit, an elevator group control unit and an execution unit, the monitoring unit is used for activating the elevator group control unit and the execution unit in the control operation module where the monitoring unit is located, the elevator group control unit of only one control operation module is activated at the same time, the elevator group control unit is used for collecting a system calling instruction and producing an elevator operation instruction after being activated, and the execution unit is used for executing the elevator operation instruction to control elevator operation. When the external power supply of the elevator group is powered off, the control operation module of each elevator capable of operating starts to work, centralized management is carried out on the elevators capable of operating, appropriate elevators are allocated for calling to respond to calling, and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator group control operation system and method. Background technique [0002] In recent years, with the rapid development of domestic urban construction, high-rise buildings and intelligent buildings continue to emerge, and elevators as a vertical transportation tool have been more and more widely used. In a large building, especially a large office building, only a single elevator cannot cope with all passenger flows well, so several or more elevators need to be installed, but if multiple elevators cannot assist each other, but operate independently in parallel, when passengers simultaneously When the hall call buttons of several elevators are pressed, several elevators may respond to the same call signal, resulting in a lot of no-load operation and unnecessary truces, resulting in a reduction in the working efficiency of the elevators, and under frequent de...

AI Technical Summary

Problems solved by technology

However, in the current elevator group controlled by the group control cabinet, when the external power supply of the elevator is out of power (the building is powered off), and the elevator is powered by the backup power supply, due to the limited power supply of the backup power supply, some elevators may be out of service. The group control cabinet controls the elevators according to The operation mode of a single elevator, or the odd-numbered floor stop, or the even-numbered floor stop mode to pick up and drop off passengers, resulting in limited transportation capacity
