Specific implementation mode

[0023] In order to make the purpose, technical solution and advantages of this utility model clearer, the following further details this utility model in combination with the drawings and embodiments.

[0024] In one embodiment, as Figures 1-5 shown, a face recognition access control device includes a top plate 100, a bottom plate 500, a protection mechanism 200. The upper end of the protection mechanism 200 is connected to the top plate 100, a door panel 400. There are two door panels 400. The upper end of the door panel 400 is connected to the upper ends of the top plate 100 and the protection mechanism 200. The lower end of the door panel 400 is connected to the bottom plate 500, and a main body mechanism 300. The main body mechanism 300 is located below the protection mechanism 200 and is centered directly in front of the two door panels 400. By arranging the protection mechanism 200 above the main body mechanism 300, it can timely prevent the main body mechanism 300 from being affected by the outside world such as dust and rain when not in use, thereby effectively protecting the face recognition access control device.

[0025] The protection mechanism 200 includes a shielding plate 201 and a sponge cleaning strip 202. The sponge cleaning strip 202 is arranged on the inner side wall of the shielding plate 201. Through this setting, after the main body mechanism 300 rises and enters the protection mechanism 200, the sponge cleaning strip 202 can timely clean the dust and stains on the surface of the main body mechanism 300, so as to always maintain the clear effect of portrait recognition of the face recognition system.

[0026] The main body mechanism 300 includes a camera 302 which is located exactly in the middle above the main body mechanism 300, two fill light lamps 301 which are symmetrically arranged above the camera 302, a face recognition machine 303 which is located directly below the camera 302, an access control card swiping machine 304 which is located directly below the face recognition machine 303, three human height measurement modules 305 which are evenly distributed below the access control card swiping machine 304, a support frame 307 which is located on the back of the face recognition machine 303 and is rectangular in shape. The upper and lower sides of the support frame 307 are both sharp blade structures. There are two magnetic plastic strips 306 which are symmetrically arranged on the inner side wall of the door panel 400 close to the support frame 307. The magnetic plastic strips 306 are in close contact with both sides of the support frame 307. By arranging the fill light lamps 301 on both sides above the camera 302, the camera 302 can accurately capture face images at night, facilitating people's night travel. The setting of the access control card swiping machine 304 enables people to pass through when face recognition cannot be used under special circumstances. The structural setting of the support frame 307 and the position design of the magnetic plastic strips 306 can effectively protect the lifting mechanism inside the door panel 400, and at the same time facilitate the up and down movement of the support frame 307 under the action of the lifting mechanism.

[0027] The lifting mechanism includes a guiding block 308. The front of the guiding block 308 is connected to a support frame 307. There are two connecting columns 310, symmetrically arranged on both sides of the guiding block 308 and connected to the guiding block 308. There are two limiting wheels 309, symmetrically arranged on both sides of the connecting columns 310 and connected to the connecting columns 310. There are 2 pairs of guide rails 311, with 2 guide rails in each pair. The 2 pairs of guide rails 311 are symmetrically arranged between the guiding block 308 and the limiting wheels 309 respectively. Each pair of guide rails 311 is arranged on both sides of the connecting columns 310. The tops of the 4 guide rails 311 are connected to the top plate 100, and the bottoms of the 4 guide rails 311 extend to the bottom plate 500. There is an electric push rod 312. The electric push rod 312 is divided into upper and lower parts. The upper output end of the electric push rod 312 is connected to the bottom end of the guiding block 308, and the lower bottom end of the electric push rod 312 is connected to the bottom plate 500. The entire electric push rod 312 is located at the center of the area surrounded by the four guide rails 311 and does not contact the four guide rails 311. The main body mechanism 300 is connected to the lifting mechanism by setting the support frame 307. When someone approaches the face recognition access control device, the camera 302 on the face recognition machine 303 captures the face image of the approaching person and sends the captured face image to the face recognition machine 303. The face recognition machine 303 sends the captured image to the human height measurement module 305 for analysis, so as to judge the height of the person in the captured image. According to the analysis data judgment result of the human height measurement module 305, a signal to raise or lower the electric push rod 312 is output to the electric push rod 312. After receiving the signal, the electric push rod 312 raises or lowers the electric push rod 312 according to the signal sent by the human height measurement module 305. The electric push rod 312 drives the guiding block 308 to move up and down on the guide rails 311. At the same time, the guiding block 308 drives the support frame 307 and the main body 300 of the face recognition access control device to rise or fall, completing the up and down movement of the main body 300 of the face recognition access control device. Therefore, the height of the main body 300 of the face recognition access control device can be adjusted according to the actual height of the person to meet the usage experience of people with different heights. At the same time, by using the electric push rod 312, the main body 300 of the face recognition access control device can be quickly lifted and lowered, effectively improving the efficiency of the face recognition access control device and enhancing the actual application of the main body 300 of the face recognition access control device.

[0028] The height of the top end of the baffle 201 is flush with the top plate 100. The side width of the baffle 201 is adapted to the side width of the lower main body mechanism 300 outside the door panel 400. And the side height of the baffle 201 is flush with the bottom edge of the face recognition machine 303 on the main body mechanism 300 when the lifting mechanism reaches the top of the guide rail 311. Through this setting, the main body mechanism 300 and the protection mechanism 200 can be matched with each other, enabling the main body mechanism 300 to rise or fall smoothly. When the main body mechanism 300 is not in use, it can rise into the protection mechanism 200 for dust protection and surface stain cleaning. At the same time, the access control card reader 304 and the human height measurement module 305 below are exposed. Whenever a person approaches the face recognition access control device, the sensor inside the human height measurement module 305 sends an induction signal to the human height measurement module 305. After receiving the signal from the sensor, the human height measurement module 305 immediately outputs a signal to lower the electric push rod 312 to the electric push rod 312. After receiving the signal, the electric push rod 312 lowers according to the signal sent by the human height measurement module 305. The electric push rod 312 drives the guide block 308, the support frame 307, and the main body 300 of the face recognition access control device integrated machine to lower to the position height where the face recognition machine 303 can capture the face image of the person, thus ending the downward movement process of the main body 300 of the face recognition access control device integrated machine.

[0029] The electric push rod 312 is electrically connected to the face recognition machine 303 and the human height measurement module 305 through the guide block 308. The model of the electric push rod 312 is DLT-600. Through this setting, the recognition device of the face recognition machine 303, the analysis device of the human height measurement module 305, and the pushing device of the electric push rod 312 can cooperate in a linkage manner to jointly complete the face recognition task for people of different heights.

[0030] The diameter of the limit wheel 309 is larger than the diameter of the connecting column 310. The diameter of the connecting column 310 is adapted to the distance between the guide rails 311 on both sides of the connecting column 310. Through this setting, when the electric push rod 312 drives the guide block 308 to move up and down, the connecting columns 310 on both sides of the guide block 308 move up and down in the guide rails 311. The diameter setting of the limit wheel 309 can prevent the connecting column 310 from falling off when moving quickly in the guide rails 311, thus effectively ensuring the smooth progress of the ascending or descending movement of the lifting mechanism.

[0031] The support frame 307, the guide block 308, the connecting column 310, and the guide rail 311 are all made of aluminum alloy, and the limit wheel 309 is made of plastic. With this setting, the support frame 307, the guide block 308, the connecting column 310, and the guide rail 311 can have the characteristics of high strength, wear resistance, and corrosion resistance, improving the service life of the face recognition device. At the same time, the plastic material of the limit wheel 309 has the characteristics of durability, waterproofness, and light weight, which is more conducive to the up and down movement of the lifting mechanism, thus promoting the completion of the recognition progress of the face recognition access control device.

[0032] In the present utility model, through the mutual cooperation of the protection mechanism, the main body mechanism, and the lifting mechanism, on the one hand, the problem that the camera on the face recognition access control device is prone to dust accumulation is solved, and on the other hand, the face recognition needs of people with different heights are met, thus making it more convenient for people to use face recognition.

[0033] Working principle: When in use, the camera 302 on the face recognition machine 303 captures the face image of the approaching person and sends the captured face image to the face recognition machine 303. The face recognition machine 303 sends the captured image to the human height measurement module 305 for analysis, thereby judging the height of the person in the captured image. According to the analysis data judgment result of the human height measurement module 305, a signal to raise or lower the electric push rod 312 is output to the electric push rod 312. After receiving the signal, the electric push rod 312 raises or lowers the electric push rod 312 according to the signal sent by the human height measurement module 305. The electric push rod 312 drives the guide block 308 to move up and down on the guide rail 311. At the same time, the guide block 308 drives the support frame 307 and the main body 300 of the face recognition access control device to raise or lower, completing the up and down movement of the main body 300 of the face recognition access control device. When no face image of the approaching person is detected, the face recognition access control device can rise into the protection mechanism for protection and cleaning. During this period, when a person approaches the face recognition device, the sensor inside the human height measurement module 305 sends an induction signal to the human height measurement module 305. After receiving the signal from the sensor, the human height measurement module 305 immediately outputs a signal to lower the electric push rod 312 to the electric push rod 312. After receiving the signal, the electric push rod 312 lowers the electric push rod 312 according to the signal sent by the human height measurement module 305. The electric push rod 312 drives the guide block 308, the support frame 307, and the main body 300 of the face recognition access control device to lower to the position height where the face recognition machine 303 can capture the face image of the person, and then analyzes the height of the captured person image, repeating this process back and forth, and finally completing the entire process of the face recognition access control device.

[0034] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
