[0002] With the development of technology, in order to save labor costs, some parking lots no longer arrange personnel at the entrances and exits to release vehicles. Instead, they use integrated license plate recognition equipment. Integrated vehicle recognition equipment is an intelligent device that integrates multiple functions such as license plate recognition, image acquisition, data processing, storage and transmission. It can quickly release and charge vehicles entering and exiting.

[0004] The aforementioned smart license plate recognition machine uses a spray system to clean the surface of the viewing panel during use. However, when recognizing vehicle license plates, it sometimes fails to recognize them due to factors such as the vehicle's parking position or size. This requires the user to constantly adjust the vehicle's position, affecting the user experience. Furthermore, most existing smart license plate recognition machines raise the barrier by rotating a horizontal bar when allowing vehicles to pass. The distance and duration of the raising are fixed and cannot be adjusted for different vehicles, affecting the efficiency of vehicle passage. In addition, this method of raising the barrier is limited by space; when the horizontal bar is long, it may hit the ceiling. Utility Model Content

[0024] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0025] Please refer to Figures 1-5This utility model proposes an unattended license plate recognition integrated machine, including two sets of mounting plates 1 for mounting and fixing the device. The two sets of mounting plates 1 are symmetrically arranged. A first protective shell 2 is installed on the top of the mounting plate 1 to protect the electric telescopic rod 6. A second protective shell 3 is installed on the top of the first protective shell 2 to protect the drive motor 7, transmission screw 8 and other structures. A recognition component is arranged between the mounting plates 1. The recognition component is used to recognize vehicle license plates and release vehicles. A display screen 4 is embedded in the side wall of the second protective shell 3 to display vehicle information and toll QR code and other information. A sliding opening 5 is opened on the side wall of the second protective shell 3 to limit the movement of the barrier plate 13 and ensure the vertical movement of the barrier plate 13. A bellows cover is slidably arranged in the sliding opening 5 to seal the sliding opening 5 and prevent dust or liquid from entering the second protective shell 3.

[0026] The identification component includes an electric telescopic rod 6 and a drive motor 7. The electric telescopic rod 6 is bolted into the first protective shell 2 and is used to adjust the height of the second protective shell 3. The drive motor 7 is bolted into the second protective shell 3 and is used to drive the rotation of the transmission screw 8. The output end of the drive motor 7 is fitted with the transmission screw 8. A winding wheel 9 is fitted around the top of the transmission screw 8 for loosening or winding the connecting rope 15. The output end of the electric telescopic rod 6 is connected to the bottom of the second protective shell 3. A fixing rod 10 is installed on the side wall of the first protective shell 2. A first cleaning brush 11 is installed on the side wall of the fixing rod 10 for cleaning the display screen 4. The first cleaning brush 11 is attached to the side wall of the second protective shell 3. A screw nut 12 is fitted around the transmission screw 8. A blocking plate 13 is installed on the side wall of the screw nut 12 for blocking vehicles. In the initial state, the blocking plate 13... The barrier 13 is located at a low position. After a vehicle completes payment or identification, the identification device 22 sends a command to the electric telescopic rod 6 and the drive motor 7. The electric telescopic rod 6 drives the second protective shell 3 to rise, causing the barrier 13 to rise as a whole. The drive motor 7 drives the transmission screw 8 to rotate clockwise, which in turn drives the screw nut 12 to move upward. The upward movement of the screw nut 12 causes the barrier 13 to move, allowing the barrier 13 to be raised quickly, thus enabling the vehicle to pass quickly. The vertical lifting method improves the applicability of the equipment. After the vehicle has completely passed the barrier 13, the electric telescopic rod 6 drives the second protective shell 3 to reset, and the drive motor 7 drives the transmission screw 8 to rotate counterclockwise, causing the barrier 13 to reset quickly, ensuring the blocking of subsequent vehicles. During the process of the second protective shell 3 moving upward or resetting, the first cleaning brush 11 can clean the surface of the display screen 4, which is beneficial for subsequent users to scan or view the code.

[0027] Guide wheels 14 are installed on the side walls of the barrier plate 13 and the second protective shell 3 to guide and limit the connecting rope 15. A connecting rope 15 is sleeved on the outside of the winding wheel 9 for pulling the second cleaning brush 18. A fixing plate 16 is installed on the side wall of the barrier plate 13. Two sets of limiting rods 17 are slidably installed inside the fixing plate 16 to limit the movement of the second cleaning brush 18, ensuring its horizontal movement. The second cleaning brush 18 is installed at the end of each limiting rod 17 for cleaning the transparent plate 21. A... A return spring 19 is provided. A through-hole 20 is provided on the surface of the barrier plate 13. The second cleaning brush 18 is attached to the surface of the barrier plate 13. The return spring 19 is located between the second cleaning brush 18 and the fixed plate 16. The second cleaning brush 18 is connected to the connecting rope 15. A transparent plate 21 is detachably installed in the through-hole 20 to ensure the recognition device 22 can recognize the vehicle license plate. The recognition device 22 is installed on the side wall of the barrier plate 13 for recognizing the vehicle license plate, controlling the raising and lowering of the barrier plate 13, and determining whether the vehicle has left. The recognition device 22 is equipped with a control... The system includes a control chip, a wide-angle camera, two sets of infrared emitters, and a supplementary light. The output ends of the two sets of infrared emitters face the through-hole 20 and the bottom of the recognition device 22, respectively. In the initial state, the reset spring 19 is compressed, and the recognition device 22 is located at the center of the barrier plate 13. This avoids the recognition of vehicle license plates being affected by angle issues, thus improving the recognition efficiency of the recognition device 22. The infrared emitters in the recognition device 22 can be used to identify the height of the vehicle and determine whether the vehicle has left. When the front infrared emitters can no longer identify the vehicle, the barrier plate 13 stops rising. When the infrared transmitter at the bottom fails to detect a vehicle, the barrier plate 13 resets. The lifting height of the barrier plate 13 can be controlled according to different vehicles, improving the efficiency of vehicle passage. During the lifting and resetting process of the barrier plate 13, the rotation of the transmission screw 8 drives the winding wheel 9 to rotate. The rotation of the winding wheel 9 can loosen or wind up the connecting rope 15. With the cooperation of the reset spring 19 and the limit rod 17, the loosening or winding of the connecting rope 15 can cause the second cleaning brush 18 to move to the right and reset, completing the cleaning of the surface of the transparent plate 21, which is beneficial for the subsequent recognition device 22 to recognize the vehicle license plate.

[0028] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
