Embodiment Construction

[0020] Such as figure 1 Shown, a kind of somatosensory temperature measurement method is carried out in the following manner:

[0021] (1) Measure the view factor of all surfaces in the environment ,surface temperature and surface blackness , where the surface number is defined as indivual, , , Respectively represent the first The blackness of a surface, the surface temperature and the surface blackness, ;

[0022] (2) Calculate the weighted value of the surface blackness :

[0023]

[0024] in Indicates the first The blackness weighting coefficient of a surface, Indicates the first the surface area of ​​a surface, represents the sum of the surface areas of all surfaces, ;

[0025] (3) Calculate the average radiation temperature :

[0026]

[0027] (4) Measure and calculate ambient air temperature , radiation heat transfer coefficient and the convective heat transfer coefficient ;

[0028] (5) Calculate and deduce the operating ...

Abstract

The invention discloses a sensible temperature measuring method, which is carried out by the following steps: (1) measuring angle coefficients, surface temperatures and surface blackness degree of all surfaces of the environment; (2) calculating to obtain a weighted value of the surface blackness degree; (3) calculating an average radiation temperature; (4) measuring and calculating an environment air temperature, a radiation heat exchange coefficient and a heat convection coefficient; (5) calculating and deducing an operation temperature; (6) measuring relative humidity and air flow speed of the environment air; and (7) calculating a sensible temperature tper. Compared with the prior art, parameters including the temperature, the humidity, the air speed and the like of the air are measured, and the radiation, the temperature and the air degree are considered, so that the obtained sensible temperature is closer to the actual feeling of a human body. The sensible temperature measuring method is particularly suitable for fields including an infant room, a patient room and the like which are sensitive to the sensible temperature, so that the peripheral environment is conveniently adjusted to enable the indoor environment to be at a more comfortable state.

Description

technical field [0001] The invention relates to a method for measuring body temperature, which can be used in places sensitive to actual temperature. Background technique [0002] Somatosensory temperature is the degree of coldness and warmth felt by the human body, taking into account the comprehensive influence of air temperature, humidity, wind speed and other factors. However, in specific applications, the air temperature is usually slightly corrected, that is, as the body temperature. This method of calculating body temperature is simple, but it does not fully consider the influence of radiation, humidity, and wind speed. The data deviates from the actual human body and is difficult to apply to places that are sensitive to actual temperature. In addition, more background technology related to this technology is the use of traditional thermometers to measure air temperature. The actual air temperature is different from the actual feeling of the human body. For example,...
