A high temperature and humidity environment can be easily formed in a confined refuge system, which has a significant effect on the safety of refugees. Human survival experiments in a closed simulation chamber were carried out under high temperature and humidity conditions (the temperature was above 27 °C and the relative humidity was above 70%). The asymmetrical five-grade scale method was used first, and human comfort voting data were collected from 35 groups under different temperature and humidity conditions. A non-linear trend of the effects of different temperature and humidity conditions on human comfort was obtained through analysis, and the boundary curves for different human comfort conditions in a closed refuge chamber were determined. At the same time, a function prediction model of the apparent temperature was established, which had instructive meaning for the study and design of the environment controls and life support system in a closed rescue space for different fields.

Structural model of plastic electronic package under temperature and humidity is constructed, and the coupling of the thermal and moisture impact on structure field is implemented. The impact of thermal expansion, hygro-swelling and vapor pressure increases with increasing initial defect, especially the impact of vapor pressure. At certain crack length, KI and KII induced by thermal expansion is proportional to temperature difference, and KI and KII induced by vapor is proportional to vapor pressure. The impacts of thermal expansion and hygro-swelling on ERR decrease during crack propagation, but the impact of vapor pressure increases significantly.

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 analysed, 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 a significant reference for the research of temperature and humidity control in tobacco industry in China.
