[0005] However, the light source positioning indicator used by the above-mentioned infrared thermometer has design disadvantages, for example, it must be measured by others to check whether the two beams of LED light irradiated merge into one point through the movement of the measuring head, and the temperature of the object P to be measured is Unable to self-check the two beams of light and the converging spot on his forehead, and thus unable to measure his forehead temperature by himself

Embodiment Construction
[0047] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:
[0048] Cooperate with reference figure 2 , which is a diagram of the use structure of the non-contact temperature sensing device capable of distance measurement of the present invention. The non-contact temperature sensing device 10 detects in advance a measurement distance between the temperature test object P and the non-contact temperature sensing device 10 when measuring the temperature of a temperature test object P, and when the measurement distance When falling within a preset measurement range, the non-contact temperature measuring device is driven to measure the temperature value of the temperature object P to be measured. In this way, the temperature measurement error caused by the non-contact temperature sensing device 10 due to the difference in measurement distance can be effectively avoided, thereby providing a...

A non-contact temperature sensing device capable of interval measurement and temperature measurement method thereof, The non-contact temperature sensing device capable of interval measurement comprises a transmission unit, a sensing unit and a one-chip microcomputer. The transmission unit transmits a signal to a temperature-to-be-measured object; the transmitted signal is reflected by the temperature-to-be-measured object so as to obtain a reflected signal which is received by the sensing unit; the one-chip microcomputer is electrically connected with the transmission unit and the sensing unit, wherein the one-chip microcomputer judges the measurement distance between the non-contact temperature sensing device and the temperature-to-be-measured object on the basis of the reflected signal; and when the measurement distance is in a preset measurement range, the one-chip microcomputer generates a temperature measurement enable signal.
Description
technical field [0001] The invention relates to a non-contact temperature sensing device, in particular to a non-contact temperature sensing device capable of distance measurement. Background technique [0002] Temperature is a physiological indicator of a living body. It can be used to know whether a living body is in a healthy state. There are some contact forehead thermometers on the market that can measure the temperature of the forehead or skin. However, these contact forehead thermometers may not There will be a risk of contact with the infection vector, so there are non-contact forehead temperature measuring devices on the market to avoid the above-mentioned risk of vector infection. [0003] The infrared temperature sensor inside the non-contact forehead temperature measuring device converts the sensed infrared temperature into a proportional voltage signal through photoelectricity, and obtains the temperature value of the object to be measured through appropriate ca...
