[0025] Specifically, a worm wheel 206 is fixedly provided on the outer wall of one side of the rotating shaft 205 , and a worm 207 is movably provided at the rear of the worm wheel 206 .
[0026] In this embodiment, by providing the rotating shaft 205 , the worm wheel 206 and the worm 207 , when the worm 207 rotates, the worm wheel 206 rotates accordingly and drives the rotating shaft 205 to rotate, thereby adjusting the angle of the identification device 301 .
[0027] Specifically, the connection relationship between the worm 207 and the worm wheel 206 is a meshing connection.
[0028] In this embodiment, by setting a worm wheel 206 and a worm 207, the helix angle of the worm 207 is smaller than the friction angle of the worm wheel 206, so the transmission of the worm 207 has self-locking properties, that is, the worm 207 can drive the worm wheel 206 to rotate, but the worm wheel 206 cannot drive the worm 207 to rotate in turn, thereby improving the stability of the identification device 301.
[0029] Specifically, a rotating handle 208 is fixedly provided at one end of the worm 207 .
[0030] In this embodiment, by providing a rotating handle 208, the provision of the rotating handle 208 enables the staff to easily adjust the angle of the identification device 301, thereby improving the work efficiency of the staff.
[0031] Specifically, the fill light 302 , the light source sensor 304 , the battery 305 and the PLC controller 306 are electrically connected to each other.

[0033] Specifically, sealing pads are fixedly provided around the sealing plate 307 .
[0034] In this embodiment, by providing the sealing plate 307 , when the sealing plate 307 is fixed, the sealing gasket can improve the sealing performance of the installation box 201 and prevent rainwater from entering the installation box 201 .
[0035] Specifically, a return spring 312 is movably disposed outside the fixing rod 311 , and the return spring 312 is connected to the fixing rod 311 in a sleeve connection.
[0036] In this embodiment, by setting a return spring 312, when the fixing rod 311 is displaced by external force, the return spring 312 will be compressed or stretched. Once the external force disappears, the return spring 312 will use its elastic potential energy to push the fixing rod 311 to return to its original position.
[0037] Specifically, sliders 314 are fixedly provided on the top and bottom of the movable plate 310 , and the sliders 314 are connected to the installation box 201 in a sliding connection.
[0038] In this embodiment, by providing a slider 314 , when the movable plate 310 moves, the slider 314 moves accordingly, thereby guiding and limiting the movement of the movable plate 310 .
[0039] When in use, the device is installed in the corresponding area and the gate machine 1 is fixed. Then, the height and angle of the identification device 301 are set, and the electric push rod 202 is started. The telescopic end of the electric push rod 202 drives the support platform 203 and the connecting seat 204 to move, thereby achieving the purpose of adjusting the height of the identification device 301. The handle 208 is turned, and the handle 208 drives the worm 207 to rotate. The worm gear 206 rotates and drives the shaft 205 to rotate, thereby adjusting the angle of the identification device 301, so that the height and angle of the identification device 301 in different channels are different. Users of different heights can choose channels according to their own needs, so as to facilitate face recognition. After the recognition is passed, the gate machine 1 controls the opening of the channel to allow the human body to pass.
[0040] The battery 305 provides electrical energy to ensure the stable operation of the system. The light intensity threshold is preset through the PLC controller 306. The light source sensor 304 can monitor the intensity of the ambient light in real time. When the light is insufficient, the PLC controller 306 will start the fill light 302 in time and dynamically adjust the brightness of the fill light 302 according to the change of light intensity, thereby providing sufficient light for the camera, thereby ensuring the clarity of the facial image and improving the accuracy of facial recognition.
[0041] In summary, the smart community face access control system is provided with a fill light 302, a light source sensor 304, a battery 305 and a PLC controller 306. The fill light 302, the light source sensor 304, the battery 305 and the PLC controller 306 are electrically connected to each other in the smart community face access control system to form a complete working system. The battery 305 provides electrical energy to ensure the stable operation of the system. The light intensity threshold is preset by the PLC controller 306. The light source sensor 304 can detect the intensity of the ambient light and convert the detected light intensity into an electrical signal and send it to the PLC controller 306. The PLC controller 306 determines whether it is necessary to turn on the fill light 302 or adjust its brightness according to the received signal and the preset logic, thereby providing sufficient light for the camera, reducing recognition problems caused by overexposure or insufficient light, ensuring clear facial images, and improving the efficiency and accuracy of facial recognition. By providing a sealing plate 307, a handle 308, a limit rod 309, a movable plate 310, The fixing rod 311, the return spring 312, the pull ring 313 and the slider 314 pull the pull ring 313 to the side away from the installation box 201, and the fixing rod 311 moves accordingly. With the cooperation of the slider 314, the movable plate 310 moves horizontally in the installation box 201, and drives the limit rod 309 to move, and the return spring 312 is deformed. When the limit rod 309 moves out of the limit groove, the limit of the sealing plate 307 is released. At this time, the handle 308 can be pulled to remove the sealing plate 307, thereby realizing the disassembly of the sealing plate 307. The same is true for the installation. The operation is simple and no tools are required. This provides great convenience for the staff to replace the battery 305 and effectively improves the work efficiency.
