Through the analysis of temperature and humidity control in the process of curing tobacco , the study studied the expert control algorithm about temperature and humidity in the flue-cured tobacco house , and then analyzed the control vari- able selection , knowledge base construction and control rules 币le expert tobacco room temperature and humidity control system was designed with C8051 F020 MCU as the core device , DS18B20 temperature and humidity sensor as the detection components ,and the liquid crystal display module as the human-computer interface. The automatic control system for flue-cured tobacco room technology has a certain application value.
