Heat comfort detection method based on physiological parameters of human body

Abstract

The invention discloses a heat comfort detection method based on physiological parameters of the human body. The method comprises the following steps: acquiring the physiological parameters of the human body, including skin temperature, an electrocardiosignal, fingertip pulse, breath and skin impedance; performing peak value identification on the electrocardiosignal to obtain a heart rate variability signal and a heart rate; performing correlation analysis on the skin temperature, the heart rate variability signal, the heart rate, the fingertip pulse, the breath and the skin impedance to acquire the correlation degree of the physiological parameters and heat comfort so as to select optimal physiological parameters; performing regression analysis on the optimal physiological parameters, and building a function relationship between the physiological parameters and the comfort degree; inputting the function relationship of the physiological parameters and the comfort degree to a BP (Back-Propagation) neural network and performing automatic heat comfort degree judgment. The method can be used for intelligently regulating the temperature of an air conditioner by detecting the physiological parameters of the human body in real time and inputting the physiological parameters into an air conditioning system, and individual variation is fully considered, so that the regulated indoor thermal environment is more similar to the expected thermal environment of the human body.

Description

technical field [0001] The invention relates to the technical field of human thermal comfort detection, in particular to a thermal comfort detection method based on human physiological parameters, and clarifies its application in an intelligent air-conditioning system. Background technique [0002] Thermal comfort refers to the state of consciousness in which people express satisfaction with the thermal environment. It is of great significance to study the technology of human comfort detection. On the one hand, with the development of science and technology, people can carry out normal work and life even without going out in today's society. People spend more and more time indoors, and the quality of the indoor environment has a great impact on people's comfort. , work efficiency and physical and mental health have a significant impact. Among the various factors affecting the indoor environment, thermal environmental factors have the most significant impact on the human bo...

Problems solved by technology

However, considering the coupling of various objective factors and human subjective factors, only using subjective evaluation methods has brought some problems to the study of thermal comfort. On the one hand, the comfort of indoor occupants is affected by a wide variety of thermal environment parameters; on the other hand On the one hand, even if they are in the same environment and set exactly the same thermal environment parameters, people with different living habits and different physiological activity states will make different subjective evaluations.
