Example 2

As shown in Figures 1-4, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes an elevator face recognition terminal device, including an elevator terminal 100, the elevator terminal 100 is internally rotatably connected to a driven rotating rod 301, one end of the driven rotating rod 301 is fixedly connected to a cleaning plate 300, the cleaning plate 300 is in contact with the face recognition camera 101, the elevator terminal 100 is internally structured with a transmission chamber 400, the transmission chamber 400 is internally structured with a driving assembly for driving the cleaning plate 300 to rotate, the driving assembly includes a gear 302 rotatably connected to the inside of the transmission chamber 400, the gear 302 is internally fixedly connected to an inner ratchet 303, the inner ratchet 303 is disposed on the outer surface of the driven rotating rod 301, the outer surface of the driven rotating rod 301 is evenly and movably connected to a plurality of ratchets 304, the ratchets 304 are adapted to the inner ratchet 303.

As an implementation method in this embodiment, as shown in Figures 1-4, one end of the pawl 304 is fixedly connected to a spring 305, one end of the spring 305 is fixedly connected to the driven rotating rod 301, a double-sided rack 406 is arranged inside the transmission chamber 400, the top of the double-sided rack 406 is meshed with the gear 302, and two telescopic rods 407 are fixedly connected inside the transmission chamber 400, the telescopic ends of the two telescopic rods 407 are fixedly connected to the double-sided rack 406, and the outer surfaces of the two telescopic rods 407 are respectively sleeved with reset springs 408, and the reset springs 408 One end is fixedly connected to the inside of the transmission chamber 400, and the other end of the return spring 408 is fixedly connected to the double-sided rack 406. The transmission chamber 400 is rotatably connected to a rotating rod 403, and an incomplete gear 404 is fixedly connected to the outer surface of the rotating rod 403. The incomplete gear 404 is meshed with the bottom of the double-sided rack 406. The transmission chamber 400 is fixedly connected to a micro motor 401, and a worm 402 is fixedly connected to the output end of the micro motor 401. A worm wheel 405 is fixedly connected to the outer surface of the rotating rod 403, and the worm 402 is meshed with the worm wheel 405.

Specifically, the micro motor 401 is turned on to drive the worm 402 to rotate. At this time, the worm 402 is meshed with the worm wheel 405 to drive the rotating rod 403 to rotate, and then the incomplete gear 404 is rotated. When the incomplete gear 404 is meshed with the double-sided rack 406, the double-sided rack 406 is driven to move close to the telescopic rod 407, thereby compressing the telescopic rod 407 and the reset spring 408. At the same time, when the double-sided rack 406 moves, its top is meshed with the gear 302 to drive the gear 302 to rotate counterclockwise. At this time, the inner ratchet 303 and the pawl 304 inside the gear 302 are released. Due to the mutual interference between the ratchet teeth of the inner ratchet 303 and the pawl 304, the inner ratchet 303 rotates to push the ratchet 304 to rotate. The pawl 304 moves away from the inner ratchet 303, thereby compressing the spring 305. When the incomplete gear 404 continues to rotate and finally disengages from the double-sided rack 406, its double-sided rack 406 is pushed by the elastic force of the return spring 408 to move in the direction away from the telescopic rod 407. At this time, the double-sided rack 406 moves to engage with the gear 302, thereby driving the gear 302 to rotate clockwise. The gear 302 rotates clockwise, thereby driving the inner ratchet 303 to rotate clockwise, so that the pawl 304 engages with the inner ratchet 303, and then drives the driven rotating rod 301 to rotate clockwise, thereby driving the cleaning plate 300 to rotate to clean the face recognition camera 101, and the face recognition camera 101 is cleaned by this reciprocating gap.

Among them, the clockwise rotation of the gear 302 drives the clockwise rotation of the inner ratchet 303, so that the inner ratchet 303 and the pawl 304 engage with each other, thereby driving the driven rotating rod 301 to rotate, so that the cleaning plate 300 contacts the face recognition camera 101 to clean it. It is worth mentioning that under the elastic force of the reset spring 408, the double-sided rack 406 is quickly reset, thereby driving the gear 302 to rotate quickly and then driving the driven rotating rod 301 to rotate quickly, cleaning the face recognition camera 101 at a faster speed, thereby reducing the probability of the cleaning plate 300 blocking the face recognition camera 101. When the gear 302 rotates counterclockwise, the inner ratchet 303 cannot engage with the pawl 304, so that the gear 302 idles and cannot drive the driven rotating rod 301 to rotate.

In summary, by providing a cleaning plate 300, the face recognition camera 101 can be cleaned, thereby cleaning its surface, thereby reducing dust adhering to the outer surface of the face recognition camera 101, reducing dust blocking the line of sight of the face recognition camera 101, and improving its sensitivity. By providing a driving component, the cleaning plate 300 can be easily cleaned intermittently, and the face recognition camera 101 can be quickly cleaned at the same time so that the cleaning plate 300 does not affect the normal recognition work of the face recognition camera 101. A worm 402 and a worm wheel 405 are provided, and there is a speed difference between the two, so that the rotating rod 403 rotates slowly, thereby enhancing the cleaning frequency of the cleaning plate 300.

Working principle: When in use, the elevator face recognition controller 202 is started, the face recognition camera 101 is turned on, and strangers are directly captured and the captured photos are transmitted to the background data manager 204. Multiple faces can also be recognized in the face recognition camera 101 at the same time, and the face recognition is transmitted to the microprocessor 200. The microprocessor 200 compares the data record storage card of the background data manager 204 with the personnel record in the data record storage card. After the comparison meets the door opening standard, the face data is compared on the local machine. If the comparison is successful, The data is then transmitted to the background data manager 204, the background data manager 204 transmits the data to the microprocessor 200, the microprocessor 200 sends the door opening signal to the face recognition controller 202, the face recognition elevator controller 203 internal call button panel of the face recognition controller 202 is turned on, the personnel can directly use the elevator, turn on the micro motor 401 to drive the worm 402 to rotate, at this time the worm 402 drives the rotating rod 403 to rotate by meshing with the worm wheel 405, and then drives the incomplete gear 404 to rotate, when the incomplete gear 404 and the double-sided rack 406 are engaged, the incomplete gear 404 and the double-sided rack 406 are engaged. When meshing, the double-sided rack 406 is driven to move closer to the telescopic rod 407, thereby compressing the telescopic rod 407 and the return spring 408. At the same time, when the double-sided rack 406 moves, its top is meshed with the gear 302, thereby driving the gear 302 to rotate counterclockwise. At this time, the inner ratchet 303 and the pawl 304 inside the gear 302 are released. Due to the mutual interference between the ratchet teeth of the inner ratchet 303 and the pawl 304, the inner ratchet 303 rotates to push the pawl 304 away from the inner ratchet 303, thereby compressing the spring 305. When the incomplete gear 404 continues to rotate, it will eventually mesh with the double-sided rack 40 When the double-sided rack 406 is out of meshing state, it is pushed by the elastic force of the return spring 408 to move away from the telescopic rod 407. At this time, the double-sided rack 406 moves to mesh with the gear 302 and drives the gear 302 to rotate clockwise. The gear 302 rotates clockwise to drive the inner ratchet 303 to rotate clockwise, so that the pawl 304 engages with the inner ratchet 303, and then drives the driven rotating rod 301 to rotate clockwise, thereby driving the cleaning plate 300 to rotate to clean the face recognition camera 101, and the face recognition camera 101 is cleaned by the reciprocating gap.
