[0020] 2. By setting up an automatic cleaning component, when the movable sleeve moves toward the outside of the dual-axis motor along with the threaded sleeve, the L-shaped movable plate will move toward one side of the access control body under the drive of the special-shaped rod, causing the baffle to open. When the movable sleeve moves toward the inside of the dual-axis motor, it drives the L-shaped movable plate to move inside the access control body to the other side of the access control body. At this time, the baffle closes the blocked ventilation slot under the action of wind, squeezes the air inside the L-shaped movable plate, and then transports it to the inside of the air collecting box through the ventilation pipe. Finally, it is sprayed toward the face recognition device through the air distribution plate and the nozzle, which can blow off the dust adhering to the outer surface of the face recognition device, thereby cleaning the face recognition device.

[0031] Reference Figure 1-6 The present invention provides a technical solution: a face recognition access control device, comprising an access control body 1, a face recognizer 3 is arranged above the access control body 1, a mounting platform 2 is arranged between the access control body 1 and the face recognizer 3, the face recognizer 3 is fixedly mounted on the top surface of the mounting platform 2, and an obstacle sensor 4 is fixedly connected to the top surface of the face recognizer 3;

By setting a height adjustment component, when the height of the person entering the site is lower than the recognition range of the face recognition device 3, the obstacle sensor 4 cannot detect the obstacle, and then the dual-axis motor 8 is started, and the dual-axis motor 8 rotates clockwise to drive the two threaded rods 9 to rotate, and the threaded sleeves 10 outside the threaded rods 9 move in opposite directions, and then the two connecting rods 13 tilt downward, thereby driving the height of the mounting platform 2 to decrease, so that the height of the face recognition device 3 is consistent with the height of the person to be recognized. The height difference of the personnel will not be too large, which is convenient for the facial recognition of the personnel to be recognized. On the contrary, when the obstacle sensor 4 detects an obstacle, the dual-axis motor 8 is started to rotate counterclockwise, so that the two threaded sleeves 10 move toward each other, driving the two connecting rods 13 to tilt upward, so that the device can be used by people of different heights. A T-shaped mounting groove 17 is provided on the bottom surface of the mounting platform 2, and a T-shaped mounting block 18 is provided inside the T-shaped mounting groove 17.

The T-shaped mounting block 18 is fixedly clamped in the inside of the T-shaped mounting groove 17, and the second movable connecting frame 12 is fixedly mounted on the bottom surface of the T-shaped mounting block 18. By arranging the T-shaped mounting groove 17 and the T-shaped mounting block 18, the second movable connecting frame 12 can be installed more stably. The top surface of the access control main body 1 is provided with a first mounting groove 6 and a second mounting groove 7, which can more conveniently carry out stable installation of the threaded rod 9 and the dual-axis motor 8.

[0035] Reference Figure 2-6In a preferred embodiment, the L-shaped movable plate 23 is movably connected to the inside of the gas collecting box 5, and the four sides of the L-shaped movable plate 23 are tightly fitted with the four inner walls of the gas collecting box 5. A ventilation slot 24 is provided on one side surface of the L-shaped movable plate 23, and a baffle 26 is provided on one side surface of the ventilation slot 24. A third movable connecting frame 25 is fixedly installed on one side surface of the L-shaped movable plate 23, and the baffle 26 is movably connected to the inside of the third movable connecting frame 25. A movable slot 16 is provided on one side surface of the gas collecting box 5, and a special-shaped rod 15 is movably connected to the inside of the movable slot 16. One end of the special-shaped rod 15 is fixedly connected to the movable sleeve 14. The movable sleeve 14 It is fixedly connected to one side surface of the threaded sleeve 10, and the other end of the special-shaped rod 15 is fixedly connected to one side surface of the L-shaped movable plate 23. The top surface of the mounting platform 2 is fixedly installed with an air collecting box 19, and the air collecting box 19 is located behind the face recognizer 3. One side surface of the air collecting box 19 is fixedly connected to two air distribution plates 20, and the bottom surfaces of the two air distribution plates 20 are provided with nozzles 21. The top surface of the air collecting box 5 is provided with a ventilation pipe 22, and one end of the ventilation pipe 22 is fixedly connected to the top surface of the air collecting box 5 and extends to the interior of the air collecting box 5. The other end of the ventilation pipe 22 is fixedly connected to one side surface of the air collecting box 19 and extends to the interior of the air collecting box 19. By setting an automatic Cleaning assembly, when the movable sleeve 14 moves toward the outside of the dual-axis motor 8 along with the threaded sleeve 10, the L-shaped movable plate 23 will move toward one side of the access control body 1 under the drive of the special-shaped rod 15, causing the baffle 26 to open, and when the movable sleeve 14 moves toward the inside of the dual-axis motor 8, it drives the L-shaped movable plate 23 to move toward the other side of the access control body 1 inside the access control body 1. At this time, the baffle 26 closes the blocked ventilation slot 24 under the action of wind force, squeezes the air inside the L-shaped movable plate 23, and then transports it to the inside of the air collecting box 19 through the ventilation pipe 22, and finally sprays it to the face recognition device 3 through the air distribution plate 20 and the nozzle 21, so that the sticky The dust attached to the outer surface of the face recognizer 3 is blown off, thereby realizing the cleaning of the face recognizer 3. The top surface of the third movable connecting frame 25 is fixedly installed with an inclined plate 27, and the inclined plate 27 is located on one side of the baffle 26. The inclined plate 27 is fixedly installed at a forty-five degree angle on the top surface of the third movable connecting frame 25. By setting the inclined plate 27, the baffle 26 will not continue to fall downward when it is opened, thereby blocking the baffle 26. There are multiple nozzles 21, and the multiple nozzles 21 are equidistantly installed on the bottom surface of the air distribution plate 20. By setting multiple nozzles 21, the air ejected by the nozzle 21 can be made more uniform, which makes the cleaning effect of the face recognizer 3 better.

[0036] Specifically, the working process or working principle of the face recognition access control device is as follows: when in use, the person entering the venue who needs face recognition first performs face recognition on the face recognition device 3. When the face recognition is successful, the gate of the access control body 1 can be opened to allow passage. When the height of the person entering the venue is lower than the recognition range of the face recognition device 3, the obstacle sensor 4 cannot detect the obstacle, and the dual-axis motor 8 can be started. The dual-axis motor 8 rotates clockwise to drive the two threaded rods 9 to rotate, and the threaded sleeves 10 on the outside of the two threaded rods 9 move in opposite directions under the action of the threaded sleeves. Then the two connecting rods 13 tilt downward, thereby driving the height of the mounting platform 2 to decrease, and also That is to drive the height of the face recognition device 3 to be lowered. When the obstacle sensor 4 detects an obstacle in front, the rotation of the dual-axis motor 8 can be stopped, so that the height of the face recognition device 3 and the height of the person to be recognized will not be too different, which is convenient for the face recognition of the person to be recognized. On the contrary, when the obstacle sensor 4 detects an obstacle, the dual-axis motor 8 is started to rotate counterclockwise. According to the same principle, the two threaded sleeves 10 move toward each other, and then drive the two connecting rods 13 to tilt upward, that is, drive the face recognition device 3 to move upward. When the obstacle sensor 4 cannot detect an obstacle, the dual-axis motor 8 stops rotating, so that the device can be used by people of different heights.

[0037] During the movement of the threaded sleeve 10, the movable sleeve 14 and the special-shaped rod 15 can be driven to move. When the movable sleeve 14 moves toward the outside of the dual-axis motor 8 along with the threaded sleeve 10, the external wind will enter the interior of the air collecting box 5 through the movable groove 16, and then the L-shaped movable plate 23 will move toward one side of the access control body 1 under the drive of the special-shaped rod 15. The wind entering the air collecting box 5 will open the baffle 26 through the ventilation groove 24, thereby entering the interior of the L-shaped movable plate 23. When the movable sleeve 14 moves toward the inside of the dual-axis motor 8, the wind will enter the L-shaped movable plate 23. When the L-shaped movable plate 23 moves, it drives the L-shaped movable plate 23 to move inside the access control body 1 to the other side of the access control body 1. At this time, the baffle 26 closes the blocked ventilation slot 24 under the action of wind. During the continuous movement of the L-shaped movable plate 23, the air inside the L-shaped movable plate 23 is squeezed, and then transported to the inside of the air collecting box 19 through the ventilation pipe 22, and finally sprayed to the face recognition device 3 through the air distribution plate 20 and the nozzle 21. In this way, the dust adhering to the outer surface of the face recognition device 3 can be blown off, thereby cleaning the face recognition device 3.

[0038] It should be noted that the stepper motor 170 and the pump body 220 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
