| Aiming at the problems of high energy consumption, scattered distribution and difficult management in the current use of outdoor cabinets, a STM32 based intelligent ventilation and energy saving control system for outdoor cabinets was proposed. The hardware structure of the outdoor cabinet intelligent ventilation energy saving control terminal based on STM32 was designed, and the CPU main control unit and each part of the auxiliary circuit was introduced.The RS485 interface circuit was adopted to collect the temperature and humidity inside and outside the cabinet and the operation data of the equipment in the cabinet.The DI circuit was designed for the detection of fault conditions such as smoke and water leakage. Ethernet circuit was designed to upload collected data. The DO circuit was designed to control the ventilation system. Based on the idea of finite state machine, the temperature difference, humidity outside the cabinet and the running status of the cabinet were taken into account, and the intelligent ventilation control system software was designed. The experimental results show that the system can not only effectively reduce the running time of the air conditioner, but also can timely respond and alarm in case of malfunction. This terminal can effectively reduce the energy consumption and management difficulty of outdoor cabinets. |
