For example, when the individual being tested is getting on the bus, but the ambient temperature of the bus shelter where he was before is very different from the ambient temperature in the bus. In the body temperature detection when you just get on the bus, you need to quickly know the ambient temperature of the bus shelter to ensure the correct body temperature value. It can be seen that different room temperature will lead to inaccurate body temperature measurement results. In order to reduce the influence of environmental factors on body temperature detection and obtain more accurate body temperature detection results, this method not only detects the ambient temperature in the body temperature detection area of the measured individual, that is, the internal ambient temperature (Ta_internal), but also detects the temperature of the environment before entering the detection area. The temperature is the external ambient temperature (Ta_external). This method calculates the corresponding correction parameters according to the relationship between the internal and external ambient temperature, the body surface temperature (Tb_internal) and the actual body temperature (Tb) corresponding to the body surface temperature in the process of correcting the results of the temperature difference between different environments. . This method constructs two-layer quantitative relationship according to relevant parameters: the first layer is to construct the ambient temperature in the body temperature detection area of the measured individual, namely the internal ambient temperature (Ta_internal), and the ambient temperature of the area where the measured individual is located before entering the detection area, that is, the external environment.

A body temperature detection compensation value (Tb_comp) corresponding to the internal and external ambient temperature is calculated to obtain the actual body temperature (Tb) corresponding to the body surface temperature. In this detection method, the above corresponding quantitative relationship is pre-stored in the processing module, and then a temperature correction mechanism is established, wherein the actual body temperature (Tb) can be measured according to an armpit thermometer or other similar devices. After the temperature correction mechanism is established, when the actual body temperature is detected, the internal ambient temperature, the external ambient temperature and the body surface temperature of the measured individual are imported into the temperature correction mechanism to generate the corrected human body temperature value. During detection, when this method starts to work in the device, it will first run the first layer of the quantitative relationship in the temperature correction mechanism, and obtain the body temperature compensation value according to the received internal and external ambient temperatures. When the measured individual appears, then run the temperature correction. The second layer of quantitative relationship in the mechanism is based on the real-time collected body surface temperature of the tested individual to obtain the actual body temperature of the tested individual. The measurement results obtained by the detection method are more accurate, and the reliability of the body temperature detection of the population is effectively ensured. The device will judge and display the obtained test results. If the test results exceed the normal body temperature range, the device will issue an alarm signal while displaying the results, so that the staff can carry out timely measures on the suspected cases. Track and monitor. Based on the above content, the design steps of the detection method can be summarized as follows:

According to the relationship between the internal and external ambient temperature, the body surface temperature and the actual body temperature corresponding to the body surface temperature, the correction parameters are calculated to determine the correction parameters, and then the temperature correction mechanism is constructed;

Import the obtained body surface temperature, internal ambient temperature and external ambient temperature of the measured individual into the temperature correction mechanism to obtain the actual body temperature detection result;
