Description

Technical Field

[0001] This utility model belongs to the field of barrier gate technology, and in particular to a barrier gate with license plate recognition function. Background Technology

[0002] Currently, barrier gates are widely used in parking lots, residential entrances and exits, toll stations and other places to control the entry and exit of vehicles. When barrier gates with license plate recognition functions have insufficient cleaning capabilities for the camera, dirt such as dust, rainwater, bird droppings, and insect corpses will gradually adhere to the surface of the camera lens. These dirt will obstruct the camera's view, making the captured license plate image blurry, incomplete or distorted. Traditional barrier gates require regular manual wiping, which reduces the accuracy of license plate recognition, reduces vehicle passage efficiency and increases equipment maintenance costs.

[0003] A search revealed Chinese patent document (authorization announcement number CN218413558U). This application relates to the field of barrier gate equipment technology and discloses a barrier gate with license plate recognition function. The solution includes a mounting base, a license plate recognizer fixedly connected to the top of the mounting base, a display on the surface of the license plate recognizer, an illumination lamp fixedly connected to the surface of the license plate recognizer, a license plate recognition camera on the top of the license plate recognizer, and a barrier gate machine fixedly connected to the top of the mounting base. A first connecting seat is rotatably connected to the rear of the barrier gate machine, a second connecting seat is provided on one side of the first connecting seat, a support frame is fixedly connected to the bottom of the second connecting seat, and an anti-collision mechanism is provided at the end of the first connecting seat. The anti-collision mechanism includes a vehicle barrier arm, with locking blocks fixedly connected to both ends of the vehicle barrier arm. Both the first and second connecting seats have locking grooves inside. The anti-collision mechanism protects the barrier gate machine from damage caused by vehicles hitting the vehicle barrier arm, thus reducing maintenance costs. This device can meet basic usage requirements, but the barrier gate requires periodic manual wiping of the camera, reducing license plate recognition accuracy, decreasing vehicle passage efficiency, and increasing equipment maintenance costs.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5The barrier gate shown includes a base 1 for fixing, a mounting bracket 104 for support welded to the top of the base 1, a display screen 105 mounted on the side of the mounting bracket 104, the display screen 105 is mounted on the side of the barrier gate body and electrically connected to the control unit, for displaying license plate recognition results, vehicle passage status, payment information and other content, for the convenience of vehicle owners and management personnel to view, and a rotating bracket 2 is rotatably mounted on the top of the mounting bracket 104;

[0027] The rotating frame 2 is internally connected to a movable frame 201. A license plate recognition camera 202 for license plate recognition is installed on the outer periphery of the movable frame 201. A cleaning frame 4 is slidably installed on the side of the license plate recognition camera 202. A lens frame 403 is internally mounted on the cleaning frame 4. A driven gear plate 402 is installed on the outer periphery of the lens frame 403. A high-lens head is installed inside the lens frame 403. The high-lens head can greatly improve the light transmittance and reduce light loss. Even in complex environments such as low light, it can capture clear and bright license plate images, significantly improving the accuracy of license plate recognition. At the same time, it effectively reduces image distortion and color difference, restores the true details of the license plate, provides high-quality image data for the license plate recognition system, and ensures that the barrier gate can quickly and stably complete vehicle identity verification and passage control. A limit frame 404 for preventing displacement of the high-lens head is connected to the side of the lens frame 403. Four locking slots 401 are provided on the side of the cleaning frame 4. A waterproof motor 3 is installed at the bottom of the cleaning frame 4.

[0028] The waterproof motor 3 prevents moisture from entering the internal circuitry and mechanical components, avoiding short circuits or corrosion damage caused by dampness and rain, ensuring stable operation of the barrier gate in adverse weather conditions such as rain and snow. Simultaneously, its sealed protective structure effectively blocks dust, oil, and other impurities, extending the motor's lifespan and ensuring the continuous and reliable lifting and lowering of the gate arm, maintaining the normal passage management function of the barrier gate system. The output shaft of the waterproof motor 3 is connected to the drive gear 301 via a coupling. When it rains, the waterproof motor 3 is turned on, driving the drive gear 301 to rotate. The drive gear 301 then drives the driven gear 402 and the lens mount 403 to rotate. The high-lens head on the lens mount 403 rotates, shaking off rainwater from the lens and ensuring its cleanliness.

[0029] A semi-circular block 302 is welded to the top of the license plate recognition camera 202. A rotating column 303 is rotatably installed inside the semi-circular block 302. Two spring-loaded springs 305 are symmetrically installed on the outer periphery of the rotating column 303. One end of the two spring-loaded springs 305 is connected to the outer periphery of the semi-circular block 302. A locking hook 304 that works with the locking groove 401 is installed on the outer periphery of the rotating column 303. When the cleaning frame 4 is brought closer to the license plate recognition camera 202, the edge of the cleaning frame 4 squeezes and lifts the locking hook 304. Finally, the locking hook 304 enters the locking groove 401 and fixes the cleaning frame 4. The spring-loaded springs 305 drive the locking hook 304 to continuously contact the locking groove 401 to ensure the stability of the cleaning frame 4.

[0030] A connecting post 203 is connected to the top of the license plate recognition camera 202. A rain cover 204 for protecting the license plate recognition camera 202 is installed at the end of the connecting post 203 away from the license plate recognition camera 202. A control box 101 is installed on the top of the base 1. A power unit 106 is installed inside the control box 101. The power unit 106 is driven by a motor to realize the raising and lowering of the barrier gate 107. The barrier gate 107 is installed on the movable part of the power unit 106. The barrier gate 107 is used to block or allow vehicles to pass. Common materials are aluminum alloy or high-strength plastic, and the surface is usually provided with reflective strips. The barrier gate 107 reflects light at night or in low-light conditions to improve visibility and prevent vehicle collisions. Its length varies depending on the actual application, generally between 2 and 6 meters. A top cover 102 is connected to the top of the control box 101, and a signal receiver 103 is installed on top of the top cover 102. The signal receiver 103, typically an embedded computer or microcontroller, is the "brain" of the barrier gate. It is electrically connected to the license plate recognition device, motor, and other components, receiving license plate information collected by the license plate recognition device, analyzing and processing it, and then controlling the motor to drive the barrier gate 107 to rise and fall according to preset rules. Simultaneously, the signal receiver 103 coordinates the work of various components, enabling the automated operation of the barrier gate 107. The license plate recognition camera 202 identifies the license plate, and the signal receiver 103 sends a signal to the vehicle passing through. The power unit 106 then lifts the barrier gate 107, allowing the vehicle to pass. The rotating frame 2 and the movable frame 201 can adjust the angle of the license plate recognition camera 202 to achieve a suitable recognition angle.

[0031] Working principle

[0032] When using this license plate recognition barrier, the cleaning frame 4 is brought close to the license plate recognition camera 202. The edge of the cleaning frame 4 presses and lifts the locking hook 304, eventually causing the locking hook 304 to enter the locking groove 401 and fix the cleaning frame 4. The spring 305 drives the locking hook 304 to continuously contact the locking groove 401, ensuring the stability of the cleaning frame 4. The license plate recognition camera 202 recognizes the license plate, and the signal receiver 103 sends a signal to the recognized vehicle. The power unit 106 drives the barrier arm 107 to lift, allowing the vehicle to pass. The rotating frame 2 and the movable frame 201 can adjust the angle of the license plate recognition camera 202 to achieve a suitable recognition angle. When it rains, the waterproof motor 3 is turned on, which drives the active gear 301 to rotate. The active gear 301 drives the driven gear 402 and the lens holder 403 to rotate. The high-lens head on the lens holder 403 rotates, shaking off the rainwater on the lens and ensuring the lens is clean.
