[0002] The human body recognition temperature measurement alarm technology is commonly used in hospitals to achieve rapid and accurate temperature measurement and identification. It can find personnel with higher body temperature, and with the help of access network construction, it can communicate and alarm after an abnormal signal is generated. In addition, since the accuracy of temperature measurement in hospitals is higher than that in other public places outdoors, a higher-precision thermocouple detection technology, i.e. a contact temperature measurement scheme, is generally used. This scheme effectively improves the detection efficiency and safety. It has the advantages of precision, real-time, long distance, etc., and avoids the time and infection risk caused by manual temperature measurement.

[0003] ‌The temperature measurement early warning device in the prior art includes non-contact and contact types, wherein the contact type measurement scheme uses a thermocouple as a core component and has the advantages of low cost and high precision, and therefore is widely used. However, due to the high frequency of use in hospitals, more human resources are occupied to guide patients to measure and use. If the patients themselves directly measure, the angle, position and pressure during measurement will change greatly, resulting in unreliable measurement results. It cannot be ensured that each measurement is in a completely standard measurement state. On the other hand, the conventional temperature measurement early warning device is exposed to the outside for a long time and lacks effective protection measures. SUMMARY

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Please see Figures 1 to 7 The present invention provides the following technical solution: an intelligent facial recognition temperature measurement and early warning device, comprising an early warning device body, the early warning device body comprising an identification and early warning component 1, a guiding mechanism 2, a disinfection mechanism 3, and a temperature measuring mechanism 28, wherein a storage compartment 24 is screwed to one end of the top of the identification and early warning component 1, a fixing plate 13 is inserted inside the storage compartment 24, and an identification camera 15 and an alarm module 14 are screwed to the surface of the fixing plate 13, a temperature measuring interlayer 21 is provided inside the identification and early warning component 1, the guiding mechanism 2 is inserted inside the temperature measuring interlayer 21, a diaphragm 8 is attached to the surface of the guiding mechanism 2, and the end of the diaphragm 8 is attached to the end of the inner wall of the temperature measuring interlayer 21, a disinfection mechanism 3 is provided at the top and bottom of the identification and early warning component 1, and the temperature measuring mechanism 28 is embedded inside the disinfection mechanism 3, and a rack 11 is welded to both the top and bottom of the guiding mechanism 2, and the guiding mechanism 2 is partially connected to the temperature measuring mechanism 28 through the rack 11. The temperature measurement and early warning device can perform facial recognition after the person being measured triggers the temperature measurement, and issue an alarm signal based on the temperature measurement data.

[0029] When using this invention, the device is fixed on a detection platform. When the person being tested performs self-measurement, they directly place their wrist inside the temperature measuring interlayer 21 and pull the inner pull plate 5 to trigger the entire guide mechanism 2 to move. This causes the guide mechanism 2 to slide towards the end where the disinfection mechanism 3 is located. During the sliding process, the temperature measuring mechanism 28 and the clamping component 35 inside the disinfection mechanism 3 are triggered to rotate. Based on this rotation effect, the wrist area is finally clamped and fixed in the temperature measuring area, so that the internal temperature sensing sheet 37 can finally fit against the bottom area of ​​the wrist to realize the temperature measurement process at this location. At the same time, with the help of the movement of the guide mechanism 2, the top recognition camera 15 and alarm module 14 are pulled out. After being pulled out, the facial information of the person being tested can be collected to achieve the purpose of identity recognition and confirmation. Based on the temperature measurement result, it is determined whether to control the alarm module 14 to generate an alarm signal.

[0030] In this embodiment, the identification and early warning component 1 includes a top plate 22 and a bottom plate 19. The temperature measuring interlayer 21 is formed between the top plate 22 and the bottom plate 19. The top plate 22 has a top layer groove 23 inside, and the bottom plate 19 has a bottom layer groove 20 in the middle. A plug-in compartment 29 is provided at the connection between the top plate 22 and the bottom plate 19, and a telescopic sleeve 30 is screwed to the end of the plug-in compartment 29. The top layer groove 23 and the bottom layer groove 20 are on the same vertical plane. The disinfection mechanism 3 is located on the outside of the top plate 22 and the bottom plate 19. An opening 25 is formed on one side of the storage compartment 24, and a sealing plate 16 is screwed to the side of the fixing plate 13. The sealing plate 16 is used to cover the surface of the opening 25. When not in use, the measurement area can be automatically sealed off. The temperature measuring interlayer 21 area is shielded by the guide mechanism 2, which reduces the probability of external dust entering the interior and blocks and protects the identification camera 15 and the alarm module 14, preventing them from being exposed to the outside for a long time and reducing the failure rate.

[0031] Specifically, the top plate 22 and bottom plate 19 block the internal temperature measuring layer 21, while the internal guide mechanism 2 blocks the sides of the temperature measuring layer 21 through the diaphragms 8 on both sides. When not in use, the push effect of the first spring ensures that the guide mechanism 2 is in the open end area of ​​the temperature measuring layer 21, so that the diaphragms 8 always enclose the inside of the temperature measuring layer 21, preventing external dust from entering the inside of the temperature measuring layer 21. At the same time, the identification camera 15 and the alarm module 14 are hidden inside the storage compartment 24, and the opening 25 is blocked by the sealing plate 16, thus achieving the effect of blocking and protecting the identification camera 15 and the alarm module 14.

[0032] In this embodiment, the guiding mechanism 2 includes a top pull plate 10 and a bottom pull plate 9, and both the top pull plate 10 and the bottom pull plate 9 have toothed racks 11 welded to their surfaces. The fixing plate 13 is welded to one end of the surface of the top pull plate 10, and a partition 6 is integrally formed between the top pull plate 10 and the bottom pull plate 9. An extension plate 7 is integrally formed on the side of the partition 6, and a diaphragm 8 is attached to the surface of the extension plate 7. A sliding plate 4 is integrally formed at one end of the bottom pull plate 9, and a pulling plate 5 is attached to the surface of the sliding plate 4. A groove 17 is formed on the inner side of the pulling plate 5, and an anti-slip protrusion 18 is provided on the inner wall of the groove 17. A first spring rod 12 is inserted into the ends of the top pull plate 10 and the bottom pull plate 9, and the end of the first spring rod 12 is welded to the inner wall of the telescopic sleeve 30. By incorporating a guide mechanism 2 within the identification and warning component 1, the person being tested is assisted in bringing their wrist into contact with the temperature measuring device 28. The entire process does not require professional guidance and ensures that the person being tested must take their temperature at a set angle and in a set position, thus making the measurement results more accurate and reliable.

[0033] Specifically, during temperature measurement, the wrist is directly inserted into the temperature measuring interlayer 21. Since the pull groove 17 of the pull plate 5 only faces the rear, the person being measured must insert their hand with the back of their hand facing upwards into the temperature measuring interlayer 21 before bending their fingers inwards to fit into the pull groove 17, gripping the pull plate 5, and applying a pushing force. This pushing effect causes the entire guiding mechanism 2 to move towards the disinfection mechanism 3, thereby rotating the temperature measuring mechanism 28 inside the disinfection mechanism 3. The rotation of the temperature measuring mechanism 28 causes the internal... The clamping assembly 35 extends outward from the inside of the disinfection box 26 through the temperature measuring window 27 area, and finally clamps and fits the wrist area of ​​the person being tested inside the temperature measuring interlayer 21, so that the temperature sensing pad 37 can fit on the skin to achieve the purpose of body temperature measurement. During this process, since the top pull plate 10 and the bottom pull plate 9 respectively control the independent rack 11 to rotate in conjunction with the gear 34 on the drive shaft 33, the rotating roller 31 is driven. Therefore, the two rotating rollers 31 will clamp and fit the wrist part at opposite but equal speeds.

[0034] In this embodiment, the disinfection mechanism 3 includes a disinfection chamber 26 and a temperature measuring window 27. The temperature measuring window 27 is formed on the surface of the top plate 22 and the bottom plate 19. An inclined plate 40 is provided on the inner wall of the disinfection chamber 26. A disinfection cavity 41 is provided inside the disinfection chamber 26, and an ultraviolet lamp tube 42 is screwed onto the inner wall of the disinfection cavity 41. The temperature measuring mechanism 28 includes a rotating roller 31 and a drive shaft 33. The rotating roller 31 is integrally formed on the surface of the drive shaft 33. A clamping groove 32 is formed on the top of the rotating roller 31, and a clamping assembly 35 is inserted into the clamping groove 32. A gear 34 is keyed to the surface of the drive shaft 33. The gear 34 meshes with a rack 11. Both ends of the drive shaft 33 are embedded into the inner wall of the disinfection chamber 26 through bearings. A groove 43 is formed on the bottom of the rotating roller 31. The clamping assembly 35 includes an arc-shaped plate 36, a second spring rod 38, and a conical plate 39. The two ends of the second spring rod 38 are welded to the surfaces of the arc-shaped plate 36 and the conical plate 39, respectively. A temperature-sensing element 37 is also installed on the clamping assembly 35 located below the base plate 19. The temperature-sensing element 37 is embedded in the surface of the arc-shaped plate 36. The second spring rod 38 passes through the interior of the groove 43. The temperature measuring mechanism 28 is rotated by an internal guiding mechanism 2, allowing it to automatically retract into the disinfection mechanism 3 after each measurement, enabling ultraviolet disinfection of areas that may come into contact with the person being measured, thus improving safety.

[0035] Specifically, when the wrist of the person being tested is guided to the temperature measurement area by the aforementioned guiding mechanism 2, the clamping component 35 will also be rotated from inside the disinfection cavity 41 until it is aligned with the wrist. During this process, when the conical plate 39 at the end of the clamping component 35 rotates, it is blocked by the inclined plate 40, causing the conical plate 39 to move toward the inside of the groove 43. This will push the second spring rod 38 and the arc plate 36 outward. Thus, when the wrist moves to the area where the rotating roller 31 is located, the arc plate 36 clamps and fits the wrist, thereby ensuring that the temperature sensing pad 37 can contact the skin and achieve the purpose of body temperature measurement.

[0036] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
