After receiving the ambient temperature information and the first person temperature information, the temperature processing module 3 needs to calculate and obtain a first temperature information and a second temperature information according to a predetermined relationship between the ambient temperature information and the first temperature threshold.
Specifically, the temperature processing module 3 calculates and obtains the first temperature information and the second temperature information according to the predetermined relationship between the environmental temperature information and the first temperature threshold, which includes the following two cases:
in the first case: when the environmental temperature information is less than or equal to the first temperature threshold, the temperature processing module 3 calculates and obtains the first temperature information and the second temperature information according to a first group of compensation formulas, wherein the first temperature information is smaller than the second temperature information.
That is, when the ambient temperature information T a When the temperature is less than or equal to H, the first temperature information and the second temperature information are respectively obtained by calculation through the following two formulas (a first group of compensation formulas), wherein the first group of compensation formulas comprise:
T l ＝K 1 +K 2 ×(T a -H)
T h ＝K 3 +K 4 ×(T a -H)
wherein, T l Is first temperature information, T h As second temperature information, T a Is ambient temperature information, H is a first temperature threshold, K 1 、K 2 、K 3 、K 4 Respectively, coefficients of different values. Wherein, K 3 >K 1 >K 2 >K 4 . And, T h >T l 。
In one embodiment, the first temperature threshold H is 25 ℃. The first set of compensation equations and the first temperature thresholds H and K in the first set of compensation equations 1 、K 2 、K 3 、K 4 The specific numerical value of (A) is obtained by analyzing and verifying under different conditions of low temperature, normal temperature, high temperature and the like, and simultaneously comparing the temperature of the mercury thermometer under the same condition to analyze and calculate.

In the present application, the first temperature information and the second temperature information may be obtained by calculation only in one of the above-described cases. Because the environment temperature information acquired at different time is different, the first temperature information and the second temperature information calculated at different time may be calculated according to the above two different situations. The relationship between the K coefficients in the two compensation equations is: k 3 >K 1 >K 2 >K 4 >K 6 >K 5 。
