Description

Technical Field

[0001] The utility model relates to the technical field of access control equipment, in particular to an all-in-one license plate recognition device. Background Art

[0002] A license plate recognition system (LPR) integrates license plate recognition technology and is commonly used in traffic management, parking lot management, toll booths, and other scenarios. Its primary function is to automatically identify and read a vehicle's license plate information and compare it with information in a database to enable vehicle monitoring, management, and toll collection. To facilitate vehicle entry and exit management, existing LPR systems typically require two levers, which in turn require two drive components to control their movement. This results in high manufacturing costs. Furthermore, in cold temperatures, the display screen of these LPR systems tends to fog, blurring the displayed QR code and making it difficult for users to scan and pay. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] License plate recognition systems primarily involve computer vision, image processing, pattern recognition, and artificial intelligence. By combining these technologies, license plate recognition systems can efficiently and accurately identify license plates in a variety of environments. With the continuous advancement of artificial intelligence and deep learning technologies, the recognition accuracy and processing speed of license plate recognition systems will continue to improve. Furthermore, with the development of the Internet of Things (IoT), license plate recognition systems will be more closely integrated with other intelligent transportation systems, enabling more efficient traffic management and services.

[0027] Example 1:

[0028] Based on the technical defects of the existing technology, please refer to Figures 1-6, the utility model provides a license plate recognition integrated device, which can achieve the effect of controlling the movement of two baffles 4 by using a motor 32 to drive, thereby reducing the number of driving components used and thus reducing manufacturing costs. The device includes a base 1, a shell 2 is mounted on the base 1, a double-rod control mechanism 3 is fixedly provided on the inner side of the top of the shell 2, the double-rod control mechanism 3 is connected to two baffles 4 respectively located on both sides of the shell 2, a support assembly 5 is fixedly provided on the outer wall of the shell 2 for maintaining the baffles 4 in a horizontal state, a display screen 6 is embedded on the front and back of the shell 2, a defogging mechanism 7 is provided on the inner side of the bottom of the shell 2 for improving the clarity of the display screen 6, and two sets of camera assemblies 8 are also installed on the top of the shell 2; when in use, when a vehicle needs to enter or exit, the double-rod control mechanism 3 can be used to control the lifting movement of the two baffles 4 respectively, thereby achieving the purpose of controlling the entry and exit of the vehicle, and under the action of the defogging mechanism 7, when the temperature is low, the heat generated by the internal electronic components when working can be blown to the surface of the display screen 6, thereby avoiding the problem of fogging and unclear visibility on the surface of the display screen 6, and finally, under the action of the camera assembly 8, the vehicle can be photographed to identify the vehicle license plate information.

[0029] To achieve motion control of the two levers 4, please refer to Figure 2 、 Figure 3 and Figure 4 The two gears 36 are fixed on two rotating shafts 37, and both are rotatably connected to the top of the shell 2 and fixed to one end of the stop rod 4; the motor 32 can drive the linear screw 33 to rotate, and the linear screw 33 drives it to move through the spiral transmission action with the I-shaped gear plate 34. When the I-shaped gear plate 34 moves to one side, it can mesh with one of the gears 36 and disengage from the other gear 36. In this way, only the stop rod 4 on one side can be driven to lift and move. If the stop rod 4 on the other side needs to be driven to move, the I-shaped gear plate 34 can be moved to the other side.

[0030] In order to improve the stability of the movement of the I-shaped tooth plate 34, two sliders 35 are fixedly provided at the bottom of the I-shaped tooth plate 34, and the two sliders 35 are respectively slidably set in two slide grooves 311 opened on the fixed plate 31; through the sliding action of the sliders 35 and the slide grooves 311, the I-shaped tooth plate 34 can be made more stable when moving horizontally.

[0031] When the I-shaped tooth plate 34 is out of mesh with the gear 36, the barrier rod 4 lacks a fixed connection point, causing the barrier rod 4 to tend to fall downward. To avoid this problem, please refer to Figure 2The support assembly 5 includes a fixed block 51 fixed to the side wall of the shell 2, and a "U"-shaped support block 52 is fixed on the fixed block 51. The support block 52 is overlapped on the bottom of the baffle rod 4; the support block 52 can be used to support the baffle rod 4 to avoid the problem of instability when the baffle rod 4 is in a horizontal state.

[0032] To facilitate the photography of license plate information, please refer to Figure 6 The camera assembly 8 includes a rotating base 81 installed on the top of the shell 2, and the rotating base 81 is rotatably connected to a fixing bracket 82, and the fixing bracket 82 is rotatably connected to a camera 83, and a rain shield 84 is fixed on the camera 83; the shooting position of the camera 83 can be adjusted by the rotating base 81 and the fixing bracket 82, and the rain shield 84 can prevent rain from falling on the camera 83 and affecting the shooting clarity.

[0033] Example 2:

[0034] When used in winter, due to the low temperature, the display screen 6 is prone to fogging, which causes the QR code on the display screen 6 to be unclear and the user cannot scan the code to pay. To solve this problem, based on the first embodiment, please refer to Figure 5 The defogger mechanism 7 includes a heating tube 71 fixed to the inside of the shell 2, a fan 72 is installed at the bottom of the heating tube 71, and ventilation pipes 73 are connected to both ends of the heating tube 71. The ventilation pipes 73 are "U"-shaped, and air outlets are provided at both ends of the ventilation pipes 73 and are embedded on both sides of the display screen 6; the electronic components inside the shell 2 will generate heat when working. In winter, the temperature inside the shell 2 will increase, which will cause the temperature of the air inside the heating tube 71 to increase. At this time, the fan 72 will work and blow the hot air through the ventilation pipe 73 to the surface of the display screen 6, so that the fog on the surface of the display screen 6 disappears, achieving the defogging effect.

[0035] To facilitate heat dissipation, heat dissipation holes 21 are opened on both side walls of the bottom of the shell 2; in summer, heat can be directly discharged through the heat dissipation holes 21 on both sides of the shell 2.

[0036] It can be seen from the above embodiment that: when a vehicle enters, the motor 32 is used to drive the linear screw 33 to rotate, and the linear screw 33 is driven to move by the spiral transmission action with the I-shaped toothed plate 34. When the I-shaped toothed plate 34 moves to one side, it can engage with one of the gears 36 and disengage with the other gear 36. In this way, only the baffle rod 4 on one side can be driven to lift and move, and then the I-shaped toothed plate 34 is reset, which can restore the baffle rod 4 on one side to a horizontal state. When the vehicle comes out, similarly, the I-shaped toothed plate 34 is moved to the other side and drives the baffle rod 4 on the other side to move.
