Abstract

The quality of tobacco baking is one of the important factors affecting the economic benefits of tobacco enterprises. Because of the low efficiency of traditional manual baking methods and the poor quality of tobacco, the economic benefits of tobacco enterprises and tobacco farmers are also greatly affected. In view of this, this research takes the temperature and humidity control as the research object, and proposes an agricultural intelligent tobacco house temperature and humidity controller based on STM32. Firstly, the general design scheme, hardware circuit design scheme and software design scheme of the control system are described, in which the human-machine interface circuit design of the hardware circuit design is emphatically analyzed, and finally, the design of this research is applied The agricultural intelligent temperature and humidity controller measures the temperature and humidity of the flue-cured tobacco house, and verifies the control effect. The results show that the temperature control accuracy based on STM32 is significantly higher than that of traditional control method, which is conducive to the improvement of tobacco baking quality. It is hoped that this study can provide certain reference and reference for the research of temperature and humidity control in tobacco industry in China.
