Human thermal sensation model based on somatosensory temperature under different activities

Thermal sensation is the subjective perception of the human body to its own thermal state, which can accurately reflect the change of human body temperature. In sports, human thermal sensation is an important psychological index reflecting the comprehensive state of the body. Calculating the thermal sensation of the human body during exercise has important application value for preventing excessive heat stress and heat damage during exercise. Based on this, this study obtains the thermal sensation of the human body in different environments and different activity states by establishing the thermal sensation model of the human body in motion. Specifically, first of all, this study uses RGB image recognition technology to identify motion types, and on the basis of the original somatosensory temperature model, the calculation formula of human somatosensory temperature under different climates is obtained. According to the different metabolism of human body in different types of activities, the thermal sensation division of human body under four activities of sitting, standing, walking and running is established, and the rationality of the model is proved by the adaptability analysis of the model. On the basis of the original model, the model not only simplifies the statistics of the water vapor pressure required for calculation, the net radiation absorbed by the human body, and the bareness of clothing, but also converts the water vapor pressure into a more easily measured surface humidity, and divides the somatosensory temperature on the basis of movement, which can better detect the state of the human body.
