Problems solved by technology
[0003] However, due to the traditional design of master-standby switching control, a fixed control architecture is usually determined in advance, and the work inheritance of each control device in the architecture is also pre-determined sequence logic, so that subsequent switching needs to be performed according to the determined sequence logic and When adding devices, the whole machine needs to stop and adjust the architecture, which reduces the fault tolerance and scalability of each control device

The present application relates to a group control method, system, control center equipment and storage medium of an air-conditioning group system. The method includes: when the air-conditioning group system starts to run, each control center device in the control network conducts an election, and the leader control center device and follower control center device are determined through the election, and the leader control center device controls the air-conditioning group Control by the group system; when it is determined that the leader control center equipment is abnormal, each of the follower control center equipment re-elects and determines a new leader control center equipment, and the new leader control center equipment controls the air-conditioning group system; wherein, When there is a newly-joined control center device, the newly-joined control center device also conducts an election. Adopting the method can achieve the technical effect of improving the fault tolerance and expansibility of the control equipment without being restricted by the architecture and sequence logic.
Description
technical field [0001] The present application relates to the field of computing technology, and in particular to a group control method, system, control center equipment and storage medium of an air-conditioning group system. Background technique [0002] With the development of society and economy, various intelligent applications are becoming more and more common. At the same time, under the demand of intelligent buildings, the scale of various intelligent systems and their automatic control systems is also increasing, such as central air-conditioning systems and their automatic control systems, train air-conditioning systems and their automatic control systems, etc. Then there will be a huge problem of equipment types and quantities. In order to carry out intelligent centralized and unified control of a huge system group, the group control system came into being. The main scheme adopted by the group control system is to equip each system with a general control center, ...
