[0002] At present, the metering efficiency of automatic truck scales in steel plants needs to be improved. Therefore, how to improve the automatic metering efficiency and stability has become a prominent problem in enhancing the competitiveness of steel enterprises. Automobile transportation of materials is an inevitable transportation method for each enterprise. In the fully automatic unmanned metering method, some companies adopt the method that the driver makes a metering forecast before entering the factory for metering. After the factory gate guard confirms, the vehicle drives into the fully automatic metering truck scale for metering. The automatic metering method is basically the same as that in the industry. The difference lies in the automatic recognition of vehicle numbers. Generally, there are two methods for automatic recognition of vehicle numbers. One is video recognition and capture, and the other is trigger recognition and capture (radar trigger, inductive loop trigger). Video recognition and capture has the problem that the image is not clear due to too fast vehicle speed, resulting in low recognition rate. Trigger recognition and capture (radar trigger, inductive loop trigger) can solve this problem of too fast vehicle speed.

[0003] When recognizing the license plate of a vehicle, it is mostly realized through a license plate recognition camera. However, the existing license plate recognition cameras are mainly fixedly installed and cannot be adapted to various vehicle models.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , the present utility model provides the following technical solutions: A license plate recognition and capture device includes an installation cylinder 1 and a trigger radar 1. The output end of the trigger radar 1 is electrically connected to a trigger radar 2. The output end of the trigger radar 2 is electrically connected to a vehicle number recognition camera. The output end of the vehicle number recognition camera is electrically connected to a vehicle scale weighing computer;

[0023] An L-shaped rod 4 is movably installed in the middle of the installation cylinder 1. One end of the L-shaped rod 4 is installed with a connecting ball 5. The top of the connecting ball 5 is fixedly installed with an electric push rod 16. The top end of the electric push rod 16 is fixedly installed with an installation ball 17. A connecting plate 18 is installed inside the installation ball 17. One end of the connecting plate 18 is rotatably installed with a connecting rod 9. The bottom end of the connecting rod 9 is fixedly installed with an installation plate 8. A license plate recognition camera 6 is fixedly installed inside the installation plate 8. One end of the L-shaped rod 4 is fixedly installed with a connecting disk 13. One side of the connecting disk 13 is rotatably installed with a movable disk 11. One side of the movable disk 11 is fixedly installed with a telescopic spring 10. The surface of the connecting disk 13 is fixedly installed with a second clamping strip 14. A plurality of second clamping strips 14 are provided, and the second clamping strips 14 are arranged in a circular pattern on the surface of the connecting disk 13. One side of the inner wall of the installation cylinder 1 is fixedly installed with a first clamping strip 12. A plurality of first clamping strips 12 are provided, and the first clamping strips 12 are arranged in a circular pattern on the inner wall of the installation cylinder 1.

[0024] The original trigger radar's recognition range is only a maximum of 1 meter wide and 6 meters long sector recognition area. If there is space in the middle of the vehicle, the radar will be released. In order to obtain a larger recognition area, the trigger radar can only be modified, and then a trigger radar is added on the original basis. The installation angle is staggered from the original, and the signal output is connected in parallel. In this way, a cross radar recognition area is obtained, which perfectly solves the problem of double triggering when there is space between the front and the compartment of some large trucks, and can effectively improve labor productivity. Since the L-shaped rod 4 is movably connected to the mounting tube 1, and the movable disk 11 is rotatably connected to the connecting disk 13, the L-shaped rod 4 can be adjusted in the vertical direction. When the L-shaped rod 4 rotates, the L-shaped rod 4 can be pushed toward the inside of the mounting tube 1, so that the first card strip 12 and the second card strip 1 4, when the angle adjustment is completed, the L-shaped rod 4 is loosened, and the connecting plate 13 can be pressed against the inner wall of the installation tube 1 under the action of the telescopic spring 10, and the first clamping strip 12 and the second clamping strip 14 are clamped with each other to fix the L-shaped rod 4, and the electric push rod 16 can be used to adjust the height of the vehicle number recognition camera 6 up and down. Since the connecting rod 9 is rotatably connected to the connecting plate 18, the vehicle number recognition camera 6 can be adjusted in the horizontal direction. The installation position of the two trigger radars DS-TMG034 (one and two) is required to be installed at a height of about 0.8 meters on the vehicle scale surface. The two trigger radars are installed up and down. The interval is about 0.5 meters. One of the two radars needs to be installed vertically and the other horizontally to ensure that the radar scanning surface is cross-shaped. The arrangement of the mounting ring 2 and the mounting hole 3 can facilitate the installation and fixation of the main tube 1. Since the multiple mounting holes 3 are arranged in a circle on the surface of the mounting ring 2, the firmness and reliability of the installation of the mounting tube 1 can be further ensured. The mounting ball 17 is threadedly connected to the mounting screw 15. The mounting screw 15 can be tightened so that the bottom end of the mounting screw 15 can be against the top of the connecting plate 18, which is convenient for installing and fixing the connecting plate 18. The L-shaped plate 4 is threadedly connected to the connecting ball 5, which can facilitate the disassembly of the device. Unloading or installation, and the setting of the LED lamp 7 can illuminate the front of the vehicle number recognition camera 6.

All electrical equipment in the device are powered by an external power supply.

[0025] In one aspect of this embodiment, the arrangement of the mounting ring 2 and the mounting holes 3 facilitates the installation and fixation of the main cylinder 1. Since the multiple mounting holes 3 are arranged in a circular pattern on the surface of the mounting ring 2, the firmness and reliability of the installation of the mounting cylinder 1 can be further ensured. The mounting ball 17 is threadedly connected to the mounting screw 15, and the mounting screw 15 can be tightened so that the bottom end of the mounting screw 15 can abut against the top of the connecting plate 18, facilitating the installation and fixation of the connecting plate 18. The L-shaped plate 4 is threadedly connected to the connecting ball 5, which facilitates the disassembly or installation of the device.

[0026] In one aspect of this embodiment, the setting of the LED lamp 7 can illuminate the front of the license plate recognition camera 6. In a dim environment at night, the license plate recognition camera 6 can still work, which is beneficial to improving the practicability and functionality of the device. The anti-rust paint coating provided on the surfaces of the mounting cylinder 1, the mounting ring 2, the L-shaped rod 4, the connecting ball 5, the license plate recognition camera 6, the mounting plate 8, the connecting rod 9, the mounting screw 15, the electric push rod 16, the mounting ball 17 and the connecting plate 18 can prevent the device from rusting easily and is beneficial to extending the service life of the device.
