Embodiment 1

[0062] like Figure 1-2 As shown, a non-contact precise temperature measurement method for the human body is applied to the controller of the temperature measurement device, and the temperature measurement device also includes a thermosensitive component and a pyroelectric component, both of which are Connected with the controller, it measures the temperature of the external environment and the surface of the human body through two independent temperature measurement components, so as to reduce the error and achieve the purpose of accurate temperature measurement. The specific steps are as follows:

[0063] S1: Obtain the resistance value of the heat-sensitive component and store it in the memory;

[0064] Specifically, the heat-sensitive component is a sensitive element, which is easily affected by the external environment, and its own resistance value changes. In this embodiment, the heat-sensitive component is an NTC resistor (negative temperature coefficient thermistor), a...

Embodiment 2

[0087] like Figure 3-6 As shown, a temperature measuring device includes a controller and a pyroelectric component arranged at the non-contact measuring end, and also includes a thermosensitive component, the thermosensitive component is arranged at the non-contact measuring end, the thermosensitive component and the pyroelectric All electrical components are connected with the controller;

[0088] The heat-sensitive component is used to monitor the ambient temperature of the human body to be tested;

[0089] The pyroelectric component is used to absorb infrared radiation emitted by the human body to generate electrical signals;

[0090] The controller is configured to implement the non-contact precise human body temperature measurement method in the first implementation.

[0091] In this embodiment, the model of the MCU used by the controller is HC32L136K8TA, and the model of the signal amplification chip U10 is DIO2361; and a controller, the thermosensitive component 1, ...

Abstract

The invention discloses a non-contact human body accurate temperature measurement method and a temperature measurement device. The non-contact accurate human body temperature measurement method comprises the following steps: firstly, measuring the environment temperature of an environment where a human body is located through a thermosensitive assembly; meanwhile, calculating the object surface temperature of the human body through an electric signal sent by a pyroelectric assembly and the environment temperature measured by the thermosensitive assembly to reduce the influence of the environment temperature on the measured object surface temperature and improve the accuracy of the object surface temperature; and substituting the object surface temperatures in different intervals into corresponding conversion formulas to convert the object surface temperature into the human body temperature in order to accurately measure and calculate the human body temperature.

Description

technical field [0001] The invention relates to the field of temperature measurement, in particular to a non-contact precise human body temperature measurement method and a temperature measurement device. Background technique [0002] In the prior art, the commonly used non-contact thermometer is an infrared thermometer, which performs non-contact temperature measurement through an infrared thermopile sensor, and the temperature measurement speed is fast, but the temperature measurement accuracy is easily affected by the ambient temperature, making it difficult to judge body temperature Whether it is normal or not, especially during the current period when the new coronavirus is rampant all over the world, accurate temperature measurement in a non-contact manner is extremely important for the prevention and control of the epidemic. [0003] Chinese patent number: CN205426345U infrared temperature measurement and thermistor thermometer, discloses an infrared temperature measu...
