Problems solved by technology
[0003] The dynamic ring system outside the group control system only monitors the important points of the water system equipment, and has no authority to control it. The system cannot update the control strategy remotely, and the control system cannot optimize its own shortcomings. The degree of intelligence is relatively low. Low
[0004] In addition, the on-site controller of the edge control system has limited computing power and cannot carry the complex iterative calculations required by artificial intelligence.
Each project operates independently, and the big data in each project cannot be managed in a unified manner, and the control strategy in the on-site controller cannot be updated conveniently and quickly
The on-site edge control system equipment has limited storage space and cannot save a large amount of data, and in the event of site failure or fire, it is likely to lose valuable operating data

The invention relates to a heating and ventilation group control method and system and a controller. The heating and ventilation group control method comprises the steps that equipment parameter information corresponding to each project is obtained; whether the equipment is in a fault-free running state or not is judged according to the equipment parameter information; an optimal control curve of the equipment is fit according to the acquired equipment parameter information corresponding to each project, and an optimal control strategy of the project is generated according to the optimal control curve; and the optimal control strategy is issued to the controller corresponding to each project at regular time. According to the heating and ventilation group control method, the problem that the computing power of a heating and ventilation group control field controller is limited is solved; and the problem that the existing group control system cannot update the control strategy according to the actual operation condition of the equipment is further solved.
Description
technical field [0001] The invention relates to the technical field of water system control, in particular to a HVAC group control method, system and controller. Background technique [0002] At present, all HVAC water system group control products on the market are edge control systems based on equipment in the computer room: PLC is used to monitor the operating status of chillers, water pumps, cooling towers and other equipment, and according to the temperature, pressure, temperature and humidity sensors in the system , the feedback value of sensors such as flowmeters, and the special algorithm carried in the controller is used to control the machine room. [0003] The dynamic ring system outside the group control system only monitors the important points of the water system equipment, and has no authority to control it. The system cannot update the control strategy remotely, and the control system cannot optimize its own shortcomings. The degree of intelligence is relativ...
