[0030] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.
[0031] Embodiment 1:
[0032] like Figure 1 to Figure 2 As shown, a barrier gate control device comprises a control box 1, a barrier gate box 2 and a driving rod 3 arranged on the barrier gate box 2, an adjusting rod 4 is vertically arranged in the middle of the driving rod 3, a telescopic rod 5 is arranged at the lower end of the adjusting rod 4, a first electric push rod 6 for driving the telescopic rod 5 to move up and down relative to the adjusting rod 4 is arranged on the side wall of the adjusting rod 4, a mounting plate 7 is arranged at the lower end of the telescopic rod 5, the mounting plate 7 is horizontally rotatably connected to the lower end of the telescopic rod 5, a driving mechanism 8 for driving the mounting plate 7 to rotate relative to the telescopic rod 5 is arranged on the mounting plate 7, a license plate capturer 9 is arranged at the bottom of the mounting plate 7, a fill light 10 is arranged at the bottom of the license plate capturer 9, two cameras 11 are symmetrically arranged on both sides of the bottom of the mounting plate 7, and a payment code display screen 12 is arranged at the upper end of the adjusting rod 4.
[0033] In the above embodiment, the control box 1 is electrically connected and controlled with the gate box 2, the license plate capture device 9, the fill light 10, the camera 11, and the payment code display screen 12 through cables respectively, and the rise and fall of the driving rod 3 is controlled by the gate box 2. The fill light 10, the camera 11, and the payment code display screen 12 installed on the mounting plate 7 can be driven by the first electric push rod 6 to move up and down to align with the vehicle license plate for scanning and recognition. The mounting plate 7 is driven by the driving mechanism 8 to drive the fill light 10, the camera 11, and the payment code display screen 12 to rotate horizontally to align with the vehicle license plate for scanning and recognition, thereby realizing adaptive scanning of license plates at different parking angles. At the same time, the recognition height can be adjusted to solve the scanning of license plates at different heights. By adjusting the position of the fill light 10, the fill light 10 can be accurately aligned with the license plate for lighting. The fill light can be completed by using a lower-power fill light 10, which reduces the power consumption of the fill light 10 and does not affect the vision of pedestrians.
[0034] like Figure 2 As shown, optionally, the driving mechanism 8 includes a driving motor 81, a first gear 82, and a second gear 83. The first gear 82 is coaxially arranged on the outer wall of the lower end of the telescopic rod 5 through its center hole, and the first gear 82 is coaxially fixedly connected to the telescopic rod 5 through a flat key. A second gear 83 that can mesh with the first gear 82 for transmission is arranged on one side of the first gear 82. The second gear 83 is coaxially arranged on the output shaft of the driving motor 81 through its center hole, and the second gear 83 is fixedly connected to the output shaft of the driving motor 81 through a flat key. The driving motor 81 is arranged below the second gear 83, and a groove is arranged at the bottom of the mounting plate 7. The driving motor 81 is vertically arranged in the groove. The outer shell of the driving motor 81 is fixed to the inner wall of the groove by screws. The driving motor 81 The output shaft of the drive motor 81 extends upward through the mounting plate 7 to the top of the mounting plate 7, and the second gear 83 is coaxially fixed to the upper end of the output shaft of the drive motor 81. The drive motor 81 drives the second gear 83 to rotate coaxially through its output shaft. The second gear 83 can mesh with the first gear 82 for transmission, and drive the first gear 82 to rotate. Since the first gear 82 is fixedly mounted on the telescopic rod 5, when the output shaft of the drive motor 81 rotates, the mounting plate 7 can be driven to rotate with the telescopic rod 5 as the center. The rotation of the mounting plate 7 can drive the fill light 10 and the camera 11 to rotate to any angle to scan and identify the license plates of multiple vehicles. The recognition ability is strong, and the vehicle does not need to frequently adjust the direction for recognition, and can achieve one-time recognition success, saving the recognition time of vehicles passing through the gate.
[0035] In this embodiment, if Figure 2As shown, a bearing mounting hole 71 is provided in the middle of the mounting plate 7, the lower end of the telescopic rod 5 is extended downward and inserted into the bearing mounting hole 71, the outer support ring of the bearing 72 is embedded in the bearing mounting hole 71, and the inner support ring of the bearing 72 is outer sleeved on the telescopic rod 5, so that the lower end of the telescopic rod 5 is rotatably supported by the bearing 72 provided in the bearing mounting hole 71, wherein the outer wall of the telescopic rod 5 and the bearing hole of the bearing 72 are installed by interference fit, so that the mounting plate 7 can rotate freely relative to the telescopic rod 5.
[0036] In this embodiment, if Figure 2 As shown, the adjusting rod 4 is cylindrical, and an axial through hole 41 is coaxially arranged at the lower end of the adjusting rod 4. The telescopic rod 5 is also cylindrical, and the outer diameter of the telescopic rod 5 is the same as the diameter of the axial through hole 41 of the adjusting rod 4. The upper end of the telescopic rod 4 is partially penetrated in the axial through hole 41 and can be guided and moved along the axial through hole 41. The fixed end of the first electric push rod 6 is connected to the side wall of the adjusting rod 4, and the fixed end of the first electric push rod 6 is hingedly connected to the hinge seat arranged on the side wall of the adjusting rod 4. The telescopic end of the first electric push rod 6 faces downward, and the telescopic end of the first electric push rod 6 is connected to the side wall of the telescopic rod 4. The telescopic end of the first electric push rod 6 is hingedly connected to the hinge seat arranged on the side wall of the telescopic rod 5. When the license plate is installed at a low height, the controller controls the first electric push rod 6 to drive its telescopic end to drive the telescopic rod 5 to move downward for a distance. Correspondingly, the mounting plate 7 moves downward, and the license plate capture device 9 also moves downward with the mounting plate 7 until the license plate capture device 9 is facing the vehicle license plate. When the license plate is installed at a high height, the controller controls the first electric push rod 6 to drive its telescopic end to drive the telescopic rod 5 to move upward for a distance. Correspondingly, the mounting plate 7 moves upward, and the license plate capture device 9 also moves upward with the mounting plate 7 until the license plate capture device 9 is facing the vehicle license plate. The position adjustment speed of the license plate capture device 9 is fast, and one-time successful recognition can be achieved.
[0037] In this embodiment, if Figure 2 As shown, the drive motor 81 is preferably a servo motor. The use of a servo motor can increase the accuracy of the rotation angle to achieve accurate recognition and positioning of the license plate orientation.
[0038] As an improved implementation of the above embodiment, Figure 1 , 2As shown, a movable block 31 is arranged on the driving rod 3, and the movable block 31 is sleeved on the driving rod 3 through a guide hole 31 arranged on its side to guide and slide, and the guide hole 311 matches the cross-sectional shape of the driving rod 3. Preferably, the cross-sectional shape of the driving rod 3 is rectangular, and the shape of the guide hole 311 is also rectangular, so that the movable block 31 can only be guided and moved on the driving rod 3 and cannot rotate. A second electric push rod 32 is arranged on the side of the driving rod 3, and the telescopic end of the second electric push rod 32 is connected and fixed to the movable block 31, and the fixed end of the second electric push rod 32 is driven by The hinged seat arranged on the side of the rod 3 is hingedly connected, the telescopic end of the second electric push rod 32 is hingedly connected to the ear seat fixed on the side of the movable block 31, and the middle part of the adjusting rod 4 is fixedly connected to the movable block 31. When the identification position is biased to the left or right, the second electric push rod 32 can be controlled by the controller to drive its telescopic end to drive the movable block 31 to move in the length direction of the driving rod 3, so that the license plate capturer 9 can be horizontally aligned with the license plate for identification. The second electric push rod 32 drives its telescopic end to drive the movable block 31 to move, and the lateral movement speed is fast, so the license plate capturer 9 can be quickly aligned with the license plate.
[0039] It can be seen from the above technical solution that when in use, when the vehicle travels in front of the driving rod 3, the position and angle of the driving vehicle can be observed through the camera 11. When the vehicle license plate is located on the left and right sides of the camera 11, the system recognizes that the vehicle position is biased to the left or right, and the controller can control the second electric push rod 32 to drive its telescopic end to drive the movable block 31 to move in the length direction of the driving rod 3, so that the license plate capture device 9 can be aligned with the license plate in the horizontal direction for recognition. The second electric push rod 32 drives its telescopic end to drive the movable block 31 to move. When the camera 11 recognizes that there is an angle between the license plate and the driving rod 3, the driving motor 81 drives the second gear 83 to rotate coaxially through its output shaft, and the second gear 83 and the first gear 82 are meshed with each other for transmission, driving the first gear 82 to rotate. Since the first gear 82 is fixedly mounted on the telescopic rod 5, When the output shaft of the driving motor 81 rotates, it can drive the mounting plate 7 to rotate with the telescopic rod 5 as the center. The rotation of the mounting plate 7 can drive the fill light 10 and the camera 11 to rotate to the angle aligned with the license plate to scan and identify the license plate. When the camera 11 recognizes that the installation height of the vehicle license plate is low, the controller controls the first electric push rod 6 to drive its telescopic end to drive the telescopic rod 5 to move downward a certain distance. Accordingly, the mounting plate 7 moves downward, and the license plate capturer 9 also moves downward with the mounting plate 7 until the license plate capturer 9 is facing the vehicle license plate. When it is recognized that the installation height of the license plate is high, the controller controls the first electric push rod 6 to drive its telescopic end to drive the telescopic rod 5 to move upward a certain distance. Accordingly, the mounting plate 7 moves upward, and the license plate capturer 9 also moves upward with the mounting plate 7 until the license plate capturer 9 is facing the vehicle license plate.
