Abstract: To improve the operational safety and reliability of air handling unit (AHU) and reduce the energy consumption of central air conditioning systems, this paper proposes a standardized design method for automatic control systems based on the swarm intelligence building platform. This method aggregates the monitoring requirements of various types of AHUs, equips them with dedicated controllers, and designs universal standard information sets, monitoring points, and control strategies, thereby effectively simplifying the design, commissioning, operation, and maintenance processes of the control system. In practical applications, this solution features fast design and deployment, convenient operation and maintenance, and accurate monitoring data, effectively ensuring the efficient operation of electromechanical equipment.
