A Combined Control Method of Temperature and Humidity Inside the Museum Cabinet

This paper analyzes the coupling of temperature and humidity in microenvironment of museum display cabinet. Based on the original temperature and humidity control system with STM32F103ZET6 as the core, the system structure was improved and a set of working mode was designed according to experience. In addition, the temperature and humidity control algorithm is improved. Based on the traditional PID algorithm, fuzzy table lookup control is introduced. Meanwhile, the refrigerating capacity (dehumidification capacity) is corrected and controlled by self-optimizing operation. After the test run, the method improves the performance of the system and reduces the waste of resources.
