Abstract

The invention discloses a control method, device and system of an air conditioning cluster. The method comprises the following steps that a plurality of controllers are powered on, and the first controller which meets preset conditions is obtained from the controllers; the first controller is controlled to enter a host mode, and all controllers except the first controller in the multiple controllers are controlled to enter a slave mode; the first controller working under the host mode controls the air conditioning cluster to work, and whether the first controller has an abnormity or not during serving as a main control device is detected; if the first controller is detected to have the abnormity, a second controller which meets the preset conditions is obtained from the controllers except the first controller, and the second controller is controlled to be switched from the slave mode to the host mode; and the second controller working under the host mode controls the air conditioning cluster to work. According to the control method, the technical problem that in the prior art, the main control device of the air conditioning cluster is a fixed controller and can not be switched is solved.

Description

technical field [0001] The present invention relates to the field of electrical equipment, in particular to a control method, device and system for an air conditioner cluster. Background technique [0002] With the development of building automation technology and central air-conditioning technology, users have higher and higher requirements for the control of central air-conditioning systems, not only requiring better cooling effect of air-conditioning, but also higher and higher requirements for energy-saving and control automation and intelligence . [0003] According to the control method of the traditional central air-conditioning group control system, independent controllers are generally used to control the air-conditioning units, water pumps, cooling towers, electric butterfly valves, sensors and other equipment in the computer room, and centralized control is performed by a fixed main controller. , However, it is impossible to switch between the independent control...
