Description

Technical Field

[0001] This invention relates to the field of rapid temperature measurement, and more specifically, to a high-precision infrared rapid temperature measurement device for faces that are obscured. Background Technology

[0002] A rise in body temperature is a powerful and reliable early warning signal for most viral infections. Due to the recent severe outbreak of COVID-19, major health organizations in China are searching for rapid, simple, non-contact, and reliable methods to detect differences in body temperature elevation. Because of the presence of glasses and masks, infrared temperature measurement signals from obstructed areas are significantly lower than those from the forehead. However, since the epidemic occurred in winter, people often wear hats, scarves, and other protective clothing outdoors. Furthermore, to combat the epidemic, everyone is required to wear masks outdoors. These facial obstructions severely affect the accuracy of temperature measurement, posing a significant challenge to epidemic prevention and control. To accurately monitor the temperature of mobile populations, the person being measured usually needs to remove their facial obstructions, which increases the risk of infection. Therefore, for moving objects in complex environments, it is difficult to accurately determine whether an object is the target based on thermal infrared image analysis. There is an urgent need to design a thermal infrared temperature measurement system that automatically identifies specific objects, accurately detects the object being measured, and extracts its surface temperature. This can be achieved through target detection technology and the fusion of infrared thermal image information to quickly measure the facial features of the human body in complex environments with temperatures as high as zero degrees Celsius.

A spiral spring sheet is provided inside the automatic winding reel.

[0006] As a further improvement of the present invention, the locking mechanism includes a locking frame, a rebounder, a suction cup, and a telescopic hose.

The suction cup is located in the middle of the inner side of the locking frame. One end of the telescopic hose is fixed to the suction cup, and the other end of the telescopic hose is located inside the locking frame.

[0007] As a further improvement of the present invention, the infrared array detector includes a slider, an electromagnetic slide rail, a swing mechanism, a detection main board, and a detection head. The slider is slidably mounted on the inner outer side of the upper end of the main housing, and the electromagnetic slide rail is fixedly mounted on the inner outer side of the upper end of the main housing.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example 1:

[0022] As attached Figure 1 To be continued Figure 5 As shown:

[0023] This invention discloses a high-precision infrared rapid temperature measurement device for faces obscured by objects. Its structure includes a base B, a support platform T, an operation panel K, and a temperature measuring mechanism C. The upper surface of the base B is fixed to the bottom of the support platform T, and the operation panel K is embedded in the upper surface of the support platform T. The top of the support platform T is fixed to the bottom of the temperature measuring mechanism C. The temperature measuring mechanism C is electrically connected to the operation panel K. The temperature measuring mechanism C includes a control host c6, a face display screen c9, a blackbody calibrator c4, and a distance calibrator c2. The face display screen c9 is embedded in the front surface of the control host c6 and electrically connected. The control host c6 is electrically connected to the operation panel K. The blackbody calibrator c4 is slidably installed inside the right end of the control host c6 and electrically connected. The distance calibrator c2 is slidably installed inside the left end of the control host c6 and electrically connected. The bottom of the control host c6 is fixed to the top of the support platform T.

[0024] The control host c6 includes a host housing c65, a transmission mechanism c64, a positioning mechanism c68, and an infrared array detector c62. A face display screen c9 is embedded in the front surface of the host housing c65. The transmission mechanism c64 is electrically connected to the face display screen c9. The blackbody corrector c4 is slidably installed inside the right end of the host housing c65, and the distance corrector c2 is slidably installed inside the left end of the host housing c65. Both the blackbody corrector c4 and the distance corrector c2 are electrically connected to the transmission mechanism c64. The positioning mechanism c68 is installed in the middle of the interior of the host housing c65. The outer side of the 68 is respectively engaged and connected to the inner end of the blackbody corrector c4 and the distance corrector c2. The infrared array detector c62 is installed on the upper end of the main body housing c65 and is electrically connected to the conduction mechanism c64. There are two locking mechanisms c68, which are installed at the upper and lower ends of the middle of the inner side of the main body housing c65. The two locking mechanisms c68 are installed in opposite directions, so that the blackbody corrector c4 and the distance corrector c2 on the left and right sides can be independently engaged and fixed, so that the blackbody corrector c4 and the distance corrector c2 can be retracted into the main body housing c65 for storage.

[0025] The conductive mechanism c64 includes a housing 4g, a temperature acquisition controller 4k, a data cable 4x, and an automatic winding reel 4j. The temperature acquisition controller 4k is located in the middle of the housing 4g and is electrically connected to the infrared array detector c62. The temperature acquisition controller 4k is electrically connected to the blackbody corrector c4 and the distance corrector c2 via the data cable 4x. The data cable 4x is wound around the outside of the automatic winding reel 4j, which is installed in the middle of the housing 4g. The device 4k is electrically connected to the face display screen c9. The outer shell 4g is fixedly installed inside the middle of the main unit shell c65. The automatic winding reel 4j is equipped with a spiral spring plate inside. The spiral spring plate can apply a spiral elastic force inside the automatic winding reel 4j, so that the automatic winding reel 4j automatically rotates to automatically wind and unwind the data cable 4x. This ensures that when the blackbody calibrator c4 and the distance calibrator c2 move on the outside, the data cable 4x is always tightly connected between the temperature acquisition controller 4k, the blackbody calibrator c4, and the distance calibrator c2.

[0026] The locking mechanism c68 includes a locking frame 85, a rebounder 89, a suction cup 83, and a telescopic hose 81. The locking frame 85 is fixedly installed inside the middle of the main housing c65, and the rebounder 89 is provided inside the locking frame 85. The suction cup 83 is located at the middle of the inner side of the locking frame 85. One end of the telescopic hose 81 is fixed to the suction cup 83, and the other end of the telescopic hose 81 is located inside the locking frame 85. There are two rebounders 89, and the suction cup 89 is located at the middle of the inner side of the locking frame 85. At both ends of the telescopic hose 81, pressing the two rebounders 89 provides ejection force for the blackbody calibrator c4 and distance calibrator c2 to move outward, ensuring that the blackbody calibrator c4 and distance calibrator c2 can be smoothly moved out of the main housing c65 for calibration. The suction cup 83 can be used to attach and fix the blackbody calibrator c4 and distance calibrator c2 inside the retractable locking frame 85, preventing the blackbody calibrator c4 and distance calibrator c2 from popping out on their own after retracting into the main housing c65.

[0027] The specific usage and function of this embodiment are as follows:

[0028] In this invention, before temperature detection of a person wearing a mask, the person stands in front of the support platform T with their face in front of the face display screen c9. By pressing the blackbody calibrator c4 and distance calibrator c2 on both sides, the blackbody calibrator c4 and distance calibrator c2 are ejected from both ends of the main unit housing c65 by the rebound device 89. During the ejection process, the blackbody calibrator c4 and distance calibrator c2 pull on the data cables 4x on both sides. At this time, the automatic rotation of the automatic winding reel 4j unwinds the data cables 4x. Conversely, the blackbody calibrator c4 and distance calibrator c2 can be retracted into the main unit housing c65 for storage. During retraction, they are fixed by suction cup 83 to prevent blackbody calibrator c4 from being pulled out of the main unit housing c65. After the body calibrator c4 and distance calibrator c2 retract into the main unit housing c65, they automatically pop out. During pop-out, the data cable 4x remains tightly connected between the temperature acquisition controller 4k, the blackbody calibrator c4, and the distance calibrator c2. The blackbody calibrator c4 and the distance calibrator c2 correct the temperature during the temperature measurement process, avoiding inaccurate temperature measurements by the infrared array detector c62 caused by personnel wearing masks or varying distances from the support platform T. After correcting the detected temperature, the data is transmitted to the temperature acquisition controller 4k, which in turn transmits the data to the face display screen c9, displaying the personnel's information and the measured temperature.

[0029] Example 2:

[0030] As attached Figure 6 To be continued Figure 7 As shown:

[0031] The infrared array detector c62 includes a slider 2d, an electromagnetic slide rail 2h, a swing mechanism 2s, a detection main board 2j, and a detection head 2t. The slider 2d is slidably mounted on the outer side of the upper end of the main housing c65, and the electromagnetic slide rail 2h is fixedly mounted on the outer side of the upper end of the main housing c65. The slider 2d is slidably mounted on the outer side of the electromagnetic slide rail 2h. The swing mechanism 2s is slidably mounted on the inner side of the upper end of the main housing c65, and the slider 2d is mounted on the outer end of the swing mechanism 2s. The swing mechanism 2s is electrically connected to the conduction mechanism c64, and the middle of the upper end of the swing mechanism 2s is connected to the middle of the detection main board 2j. Next, the detection motherboard 2j has a detection head 2t at its front end and is electrically connected. There are two sliders 2d and two electromagnetic slide rails 2h, which are symmetrically installed on both sides of the outer side of the swing mechanism 2s. This facilitates the smooth movement of the swing mechanism 2s and the detection motherboard 2j out of the upper part of the main casing c65 to detect human body temperature. The detection motherboard 2j has an arc-shaped structure, and three detection heads 2t are equidistantly arranged inside the front end of the detection motherboard 2j. The detection heads are all facial diagnostic probes, and the detection head 2t is a thermal infrared detector. Multiple temperature detections are performed on the face through the three detection heads 2t to achieve multi-point detection of facial temperature.

[0032] The swing mechanism 2s includes a connecting support plate s3, a motor s1, a rotating shaft s8, a connecting plate s6, and a telescopic sleeve s4. The connecting support plate s3 has a slider 2d at its outer end and a motor s1 inside its middle section. The output end of the motor s1 has a rotating shaft s8, which is installed with a clearance fit inside the lower end of the detection main board 2j. The connecting support plate s3 is hinged to the outer end of the detection main board 2j via the connecting plate s6, and the middle part of the connecting plate s6 passes through the telescopic sleeve s4 with a clearance fit. Two connecting plates s6 and two telescopic sleeves s4 are provided, installed symmetrically on both sides. The connecting plates s6 on both sides can automatically and elastically extend and retract inside the telescopic sleeve s4, thereby linking and pulling the connecting support plate s3 and the detection main board 2j. This ensures that the detection main board 2j can swing smoothly at the front end of the connecting support plate s3, improving the effectiveness of all-around temperature detection of the face.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In this invention, the body temperature of a person is measured by an infrared array detector c62. During measurement, the electromagnetic slide rail 2h is automatically energized, magnetically attracting the slider 2d forward. The slider 2d slides on the electromagnetic slide rail 2h, driving the swing mechanism 2s and the detection mainboard 2j to move out from the upper part of the main housing c65. After moving out, the three detection heads 2t at the front end of the detection mainboard 2j perform face array detection. At the same time, the rotation of the motor s1 drives the rotation shaft s8 to rotate. The rotation shaft s8 drives the detection mainboard 2j to rotate. During the rotation, the moving plates s6 on both sides elastically extend and retract inside the telescopic sleeve s4, linking and pulling the detection mainboard 2j and the connecting support plate s3. This ensures that the detection mainboard 2j can swing smoothly at the front end of the connecting support plate s3, improving the effect of all-round temperature detection of the face. Multiple extracted temperatures are transmitted to the temperature acquisition controller 4k, using multiple temperature detection points on the face to achieve multi-point detection of face temperature and improve the accuracy of temperature measurement.
