DETAILED DESCRIPTION

[0022] The utility model will be further described below in combination with examples.

[0023] Please refer to Figures 1-4 , the utility model provides a kind of highway ETC lane identification device, including vehicle passage 1, vehicle passage 1 top near rear end position fixedly connected with convex frame 2, and the universal joint 3 is fixedly connected on the top lower surface of convex frame 2, and ETC camera 4 is installed on the bottom of universal joint 3, and controller 5 is fixedly connected at the front end of convex frame 2, and two pressure sensors 6 are fixedly connected on the top of vehicle passage 1 near rear end position, and cavity 7 is opened in the inside of vehicle passage 1 near front end position, and blocking mechanism 8 is arranged in the inside of cavity 7.

[0024] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the bottom of the convex frame 2 is fixedly connected with a buffer pad, which can absorb the vibration and impact from the outside. Especially in the case of highway use, the vibration of the vehicle is more intense, and the buffer pad can effectively reduce the impact of vibration on the convex frame 2 and other installed equipment, reducing damage or performance degradation of the equipment.

[0025] Further as shown in Figure 1 , Figure 2 and Figure 3 , it is worth noting that the surface of the ETC camera 4 is attached with a protective film, which can effectively prevent dust, dirt, oil stains and other external substances from adhering to the surface of the camera, keeping the lens clean and improving the shooting quality and recognition accuracy of the camera. At the same time, the protective film can reduce lens reflection and glare phenomenon, improve the imaging effect of the camera in strong light conditions, and provide an additional protective layer to prevent the camera lens from being scratched by accidental collision or scratching, prolonging the service life of the ETC camera 4.

[0026] According to the above working process, it can be known that by setting the universal joint 3, the ETC camera 4 can flexibly adjust the angle according to the specific situation of the lane and the vehicle, ensuring that the camera can clearly capture images of vehicles at different angles, which helps to improve the accuracy of identifying vehicle license plates, vehicle speed and other information. At the same time, the buffer pad is arranged at the bottom of the convex frame 2, which effectively absorbs the vibration and impact when the vehicle passes, reducing the impact of these forces on the convex frame 2 and the camera, sensor and other equipment.

[0027] Further as shown in Figure 4 , it is worth noting that the blocking mechanism 8 includes a gas cylinder 801 fixedly connected to the top of the cavity 7, the output end of the gas cylinder 801 is fixedly connected with a push plate 802, the two sides of the push plate 802 are rotatably connected with a hinged rod 803, the rear end of the cavity 7 is rotatably connected with two transmission frames 804, the surfaces of the two transmission frames 804 are provided with two through grooves 805, the rear end of the cavity 7 is fixedly connected with two limiting sleeves 806, the inner walls of the two limiting sleeves 806 are slidably connected with transmission bars 807, the front ends of the two transmission bars 807 are fixedly connected with guide columns 808, the outer sides of every two corresponding transmission bars 807 are fixedly connected with chains 809, the rear end of the cavity 7 is rotatably connected with toothed discs 810 near the two sides, the front ends of the two toothed discs 810 are fixedly connected with sprockets 811, the two sides of the cavity 7 are slidably connected with straight racks 812, the outer sides of the two straight racks 812 are fixedly connected with limiting sliding plates 813, the top of the two straight racks 812 is fixedly connected with a baffle 814. By setting the blocking mechanism 8, the straight rack 812 and the baffle 814 are lifted by rotating the two toothed discs 810, thereby blocking the following vehicle, avoiding the following vehicle from avoiding toll, reducing the behavior of escaping toll, and improving the fairness and effectiveness of the ETC toll collection system.

[0028] Further as Figure 4 illustrated, it is worth noting that the rear end of the push plate 802 is fixedly connected with a limiting column slidingly connected to the inner wall of the cavity 7, which can effectively limit the sliding range of the push plate 802 in the cavity 7, thereby ensuring that the push plate 802 maintains an accurate position during operation, avoiding excessive movement or loss of control, improving the stability and precision of the entire device, making the push plate 802 slide more smoothly, avoiding violent shaking or irregular motion, and improving the smoothness and reliability of system operation.

[0029] Further as Figure 4 illustrated, it is worth noting that the two articulated rods 803 are rotatably connected to the transmission frame 804, and under the action of the articulated rods 803, the lifting movement of the push plate 802 can be converted into the rotation of the transmission frame 804, thereby providing driving force for the relative movement of the transmission bar 807.

[0030] Further as Figure 4 illustrated, it is worth noting that the plurality of guide columns 808 are slidingly connected to the inner wall of the corresponding through slot 805, and the two chains 809 are respectively installed on the outer wall of the corresponding sprocket 811. The through slot 805 drives the guide column 808 to move, so that the two chains 809 rotate simultaneously, ensuring that the movement of the two chains 809 follows the predetermined trajectory and requirements. The synchronous rotation of the two chains 809 ensures the precise action of the entire blocking mechanism 8, improving the accuracy and working efficiency of the ETC lane recognition device.

[0031] Further as Figure 4 illustrated, it is worth noting that the two straight racks 812 are respectively engaged with the corresponding toothed discs 810. The engagement of the two straight racks 812 with the toothed discs 810 enables synchronous movement, which helps to improve the precision and stability of the system. Through this engagement method, the synchronous action of the entire blocking mechanism 8 is ensured, avoiding uneven load distribution or movement errors. Moreover, the top of the vehicle passage 1 is provided with a through opening corresponding to the baffle 814, which ensures that the baffle 814 can smoothly rise and fall, improving the safety of the passage.

[0032] The scheme has the following working process: in actual use, when the current vehicle enters the vehicle passage 1 and the two front wheels contact the pressure sensor 6, the pressure sensor 6 feeds back a signal to the controller 5, the controller 5 automatically opens the air cylinder 801, the air cylinder 801 drives the push plate 802 to descend, under the action of the two hinged rods 803, the two transmission frames 804 are simultaneously rotated to drive the plurality of transmission bars 807 to move relatively, under the transmission of the chain 809, the two sprockets 811 are simultaneously rotated inward, the two toothed discs 810 are rotated to lift the straight toothed bar 812 and the baffle 814, so as to block the rear vehicle, avoid the rear vehicle following the front vehicle to avoid payment, after the current vehicle completes the ETC payment, drives away from the vehicle passage 1, the pressure sensor 6 is not subjected to any pressure, at this time the controller 5 instructs the air cylinder 801 to contract to drive the push plate 802 to rise, so that the baffle 814 descends to the inside of the cavity 7, and the rear vehicle drives to the top of the vehicle passage 1.

[0033] In summary: by setting the universal joint 3, the ETC camera 4 can flexibly adjust the angle according to the specific situation of the lane and the vehicle, ensure that the camera can clearly capture the vehicle image at different angles, help to improve the accuracy of identifying vehicle license plate, vehicle speed and other information; at the same time, the buffer pad is arranged at the bottom of the convex frame 2, which effectively absorbs the vibration impact when the vehicle passes, reduces the influence of these forces on the convex frame 2 and the camera, sensor and other equipment; by setting the blocking mechanism 8, the two toothed discs 810 are rotated to lift the straight toothed bar 812 and the baffle 814, so as to block the rear vehicle, avoid the rear vehicle following the front vehicle to avoid payment, reduce the behavior of escaping payment, and improve the fairness and effectiveness of the ETC charging system.
