Multi-dimensional personalized thermal environment control method and system based on thermal sensation recognition

Abstract

The invention discloses a multi-dimensional personalized thermal environment control method and system based on thermal sensation recognition, and the method comprises the steps: carrying out the individual image recognition of a collected infrared image of an indoor person, and obtaining the body surface temperature of an individual; determining a temperature threshold value according to the individual body surface temperature, the indoor temperature and humidity and the local thermal environment equipment operation state; according to the comparison result of the individual body surface temperature and the temperature threshold value, judging the thermal comfort state of the individual; and starting and stopping of local thermal environment equipment are controlled according to the individual thermal comfort state. Starting and stopping of local thermal environment equipment are controlled through the individual body surface temperature and the individual comfortable temperature threshold value, the differentiated requirements of different individuals for the thermal environment can be met to the maximum extent, and automatic control and operation of the personalized thermal environment are achieved.

Description

technical field [0001] The invention relates to the technical field of artificial environment and energy saving, in particular to a multi-dimensional personalized thermal environment control method and system based on thermal sensation recognition. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The method of adjusting the indoor thermal environment has typical seasonal characteristics. When the weather is hot in summer, the air conditioning and refrigeration equipment can be turned on; in winter, when the climate is cold, radiators, floor heating and air conditioning can be used for heating. These facilities all aim to create a uniform and constant thermal environment, but based on the differences in physiology, thermal adaptation and habits among individuals, there are individual differences in the demand for thermal environment, even un...

Problems solved by technology

These facilities all aim to create a uniform and constant thermal environment, but based on the differences in physiology, thermal adaptation and habits among individuals, there are individual differences in the demand for thermal environment, even under the most comfortable thermal environment recommended by the standard , there will still be some people who feel uncomfortable and dissatisfied; moreover, most of the existing thermal environment control methods are based on air temperature, humidity, etc., and also due to the differences among individuals, it is impossible to judge the thermal comfort of individuals

[0004] The personalized thermal environment control method can be used to create a personalized thermal environment according to different needs, which can meet the individual's differentiated requirements for thermal comfort to the greatest extent possible; however, because different individuals have different thermal comfort requirements, if the overall The thermal environment control method still has the above-mentioned problems, so in the indoor environment, how to meet the thermal comfort needs of different individuals is a problem that needs to be solved at present
