[0043] The linkage mechanism 22 includes a linkage plate 221; illustratively, as Figure 4 and Figure 5 shown.

[0044] A display screen 222 and a fingerprint identifier 224 are embedded and installed on one side wall of the linkage plate 221, and a camera 223 is embedded and installed on the top of the display screen 222. A mounting groove 225 is provided at the bottom of the linkage plate 221. Two sets of positioning shafts 226 are embedded and installed at the bottom of the linkage plate 221. One end of the two sets of positioning shafts 226 are rotatably connected to the outer wall of the second electric push rod 215, and the other ends of the two sets of positioning shafts 226 are fixedly connected to positioning sleeves 227, and the outer walls of the two sets of positioning sleeves 227 are fixedly connected to positioning rods 228. One set of positioning rods 226 is fixedly connected to the outer wall of the second electric push rod 215.

[0045] The protection mechanism 23 includes a top plate 231; illustratively, Figure 6 shown.

[0046] The top plate 231 is fixedly connected to side plates 232 on both sides of the bottom, and the two groups of side plates 232 are transmission-connected to the output end of the third motor 2213. A storage chamber 233 and a guide chamber 236 are provided inside the top plate 231, and the guide chamber 236 is communicated with the storage chamber 233. Two groups of first inclined holes 234 and two groups of second inclined holes 235 are provided at the bottom of the top plate 231. A micro air pump 237 is fixedly connected to one side wall of the top plate 231, and the output end of the micro air pump 237 is communicated with the guide chamber 236.

[0047] Specifically, the output ends of the two groups of the third electric push rods 2212 push the top plate 231, so that the top plate 231 moves to different positions on the top of the linkage plate 221, so as to adjust the light protection angle of the display screen 222, so that the display screen 222 is always in a state of being protected from direct light, and the display screen 222 is kept in normal use during the day. The output ends of the two groups of the third motors 2213 drive the top plate 231 to rotate, so that the top plate 231 moves to the outside of the display screen 222, so as to protect the display screen 222 when not in use;

[0048] The output end of the second motor 2210 drives the projection lamp 229 to rotate, so that the angle of the projection lamp 229 is adjusted. When the projection lamp 229 irradiates the ground, it is convenient for pedestrians to stand at the designated irradiation position. When pedestrians stand at the irradiated ground position, it can effectively prevent the jammer-related components carried by pedestrians from affecting the access control system.

[0049] The output end of the first electric push rod 212 pushes the linkage plate 221 to move up and down, so that the height of the camera 223 is adjusted, which is used to recognize the faces of pedestrians of different heights standing at the ground illumination position, and the output end of the second electric push rod 215 can make the linkage plate 221 rotate around the output end of the first motor 218 as the center during the extension and retraction process, so as to make a primary fine adjustment to the recognition angle of the camera 223, and the output end of the first motor 218 drives the linkage block 217 to rotate, so that the linkage plate 221 rotates around the positioning shaft 226 as the center, so as to make a secondary fine adjustment to the recognition angle of the camera 223;

[0050] During continuous operation, the output end of the micro air pump 237 injects gas into the guide cavity 236 and the storage cavity 233, and contacts the gas to one side wall of the linkage plate 221 through the first inclined hole 234 and the second inclined hole 235. The two groups of first inclined holes 234 are used to blow the exhausted gas onto the surface of the fingerprint identifier 224 to quickly dry the water stains on the fingerprint identifier 224 and keep the fingerprint identifier 224 in a sensitive recognition state at all times. The two groups of second inclined holes 235 are used to blow the exhausted gas onto the surface of the camera 223 to quickly clean the dirt and oil stains on the surface of the camera 223 and keep the camera 223 in a clear recognition state at all times.

[0051] The working principle of the intelligent access control recognition device proposed by the embodiment of the present invention is as follows:

[0052] The top plate 231 is pushed by the output end of the third electric push rod 2212, so that the top plate 231 moves to different positions on the top of the linkage plate 221, which is used to adjust the light protection angle of the display screen 222, so that the display screen 222 is always in a state of being protected from direct light, and the display screen 222 is kept in normal use during the day. The output ends of the two groups of the third motors 2213 drive the top plate 231 to rotate, so that the top plate 231 moves to the outside of the display screen 222, which is used to protect the display screen 222 when not in use;

[0053] The output end of the second motor 2210 drives the projection lamp 229 to rotate, so that the angle of the projection lamp 229 is adjusted. When the projection lamp 229 irradiates the ground, it is convenient for pedestrians to stand at the designated irradiation position. When pedestrians stand at the irradiated ground position, it can effectively prevent the jammer-related components carried by pedestrians from affecting the access control system.

[0054] The output end of the first electric push rod 212 pushes the linkage plate 221 to move up and down, so that the height of the camera 223 is adjusted, which is used to recognize the faces of pedestrians of different heights standing at the irradiation position on the ground. The output end of the second electric push rod 215 can make the linkage plate 221 rotate around the output end of the first motor 218 during the extension and retraction process, so as to make a primary fine adjustment to the recognition angle of the camera 223. The output end of the first motor 218 drives the linkage block 217 to rotate, so that the linkage plate 221 rotates around the positioning shaft 226, so as to make a secondary fine adjustment to the recognition angle of the camera 223.

[0055] During the continuous operation of the output end of the micro air pump 237, gas is injected into the guide cavity 236 and the storage cavity 233, and the gas is contacted to the side wall of the linkage plate 221 through the first inclined hole 234 and the second inclined hole 235. The two groups of first inclined holes 234 are used to blow the exhausted gas onto the surface of the fingerprint identifier 224 to quickly dry the water stains on the fingerprint identifier 224 and keep the fingerprint identifier 224 in a sensitive recognition state at all times. The two groups of second inclined holes 235 are used to blow the exhausted gas onto the surface of the camera 223 to quickly clean the stains and oil stains on the surface of the camera 223 and keep the camera 223 in a clear recognition state at all times.

[0056] Based on the above-mentioned intelligent access control recognition device, an embodiment of the present invention further provides an identification method of the intelligent access control recognition device, comprising the following steps:

[0057] The linkage mechanism is driven to rise and fall through the output end of the regulating mechanism;

[0059] The protective mechanism is used to self-clean and protect the linkage mechanism.

[0060] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
