Description

Technical Field

[0001] This utility model relates to the technical field of intelligent traffic license plate recognition equipment, and in particular to a solar-powered license plate recognition integrated machine. Background Technology

[0002] A license plate recognition barrier gate is an intelligent device that integrates license plate recognition technology with a barrier gate system. It uses a high-definition camera to quickly identify the license plates of vehicles entering and exiting, while simultaneously controlling the opening and closing of the barrier gate. Because the barrier arm needs to be perpendicular to the lane, the camera needs to be rotated at a certain angle to face the vehicle's license plate to obtain a good image. Therefore, traditional integrated machines require an additional column to install an auxiliary camera. The added auxiliary camera requires wiring through grooves in the ground, increasing installation costs, construction complexity, and affecting the overall aesthetics of the system.

[0003] Furthermore, traditional license plate recognition barrier gates use a single camera, which can only recognize license plates from one direction, resulting in a limited field of view. Vehicles must precisely enter the optimal recognition area. In practical applications, it frequently happens that a vehicle has arrived at the gate but is not at the camera's optimal recognition angle, leading to recognition failure and the gate not opening. This forces drivers to reverse, adjust their position, and try again, severely impacting traffic efficiency and causing a poor user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a solar-powered license plate recognition integrated machine to address the shortcomings of existing technologies.

[0005] A solar-powered license plate recognition integrated machine includes a main unit, which includes a body and several solar panels and two camera groups mounted on the outer surface of the body. The two camera groups are respectively disposed on the front and rear sides of the body with reference to the driving direction. Each camera group includes two cameras, which are embedded in the body. The two cameras in the same group are arranged facing different directions. The optical axis of the camera on the gate side is offset towards the lane side, while the camera on the side away from the gate is offset towards the opposite direction at a certain angle, and the fields of view of the two cameras overlap.

[0006] Furthermore, the top of the machine body is provided with an inclined surface, on which a solar panel is provided.

[0007] Furthermore, the top surface of the body is provided with two inclined surfaces, which are arranged in a herringbone shape.

[0008] Furthermore, it also includes a gate, which is movably mounted on the front or rear side of the machine body and can be rotated to open or close.

[0009] Furthermore, the device body includes a chassis and a top cover disposed on the top surface of the chassis. The top cover is a roof-shaped structure, which includes a square base below and an A-shaped top above. The two cameras are assembled on the front and rear sides of the base.

[0010] Furthermore, solar panels are provided on the outer surface of the chassis, the left and right sides of the base, and the outer side of the top of the A-frame.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a solar-powered license plate recognition integrated machine, which includes a main unit 10 and a gate 20 disposed on one side of the main unit 10. In this embodiment, the gate 20 is installed on the back of the main unit 10 (with the driving direction as a reference). It can be understood that in other embodiments, the gate 20 may not be installed on the back, but may be installed on the front side or independently mounted on a column.

[0022] The host 10 includes a body 11, several solar panels 12 mounted on the outer surface of the body 11, and two camera groups 13 respectively disposed on the front and rear sides of the body 11. The top of the body 11 has an inclined surface 111. The solar panels 12 are mounted on the outer side and top surface of the body 11. This inclined surface 111 design increases the area of ​​the solar panels 12, thereby significantly increasing the effective light-receiving area. Furthermore, when rainwater falls on it, gravity naturally and quickly guides the water to the lowest point of the inclined surface and drains it away, rather than accumulating into puddles as on a flat surface. Leaves, dust, and other dirt are also less likely to accumulate on the top surface, thus reducing the probability of low power generation efficiency due to water accumulation and dirt affecting light transmittance.

[0023] Specifically, the body 11 includes a chassis 112 and a top cover 113 disposed on the top surface of the chassis 112. In this embodiment, the chassis 112 is a cuboid extending vertically, and the top cover 113 is a roof-shaped structure, including a square base at the bottom and an A-shaped top at the top. The two cameras are assembled on the front and rear sides of the base, and solar panels 12 are disposed on the left and right sides of the base and the outer side of the A-shaped top. In addition, display screens 13 are disposed on the front and rear sides of the base.

[0024] The chassis 112 houses a battery box 14. The chassis 112 includes a chassis panel 1121 and a hinged door 1122. The chassis panel 1121 has recessed slots 1123 on its left and right outer surfaces and a door frame 1124 on its front surface. The hinged door 1122 is installed in the door frame 1124 via hinges and can be locked from the side (similar to a conventional door lock). Solar panels 12 are mounted on the outer surfaces of both the recessed slots 1123 and the hinged door 1122. Furthermore, a charging management circuit board (not shown) is also installed inside the chassis 112. The solar panels 12 are connected to the charging management circuit board, which in turn is connected to the battery box 14. This allows the energy from the solar panels 12 to be stored in the battery box 14, which then supplies power to the camera assembly, display screen 13, and other power-consuming units, thus achieving energy self-sufficiency.

[0025] In addition, the inner left and right sides of the chassis plate 1121 are provided with guide grooves 1125 extending in the front and back direction, and the two outer surfaces of the battery box 14 are provided with guide rails 141. The guide rails 141 are embedded in the guide grooves 1125 and can move back and forth along the guide grooves 1125 to facilitate loading and unloading and installation.

[0026] The camera assembly includes two cameras 15. Two mounting slots 114 are provided on the front and rear outer surfaces of the square base, and the cameras 15 are installed within these slots. A protective cover 151 is provided on the top outer side of each camera 15. This built-in structure design makes it easier to prevent water, dust, and other physical damage. In this embodiment, the camera is embedded within the top cover 113, with only the outer side of the lens exposed. The camera motherboard and its inner portion are also embedded within the top cover 151, eliminating the need for a separate camera housing and reducing equipment costs. Furthermore, the inner side of the body 11 is a cavity, and the chassis 112 is vertically connected to the top cover 113, providing ample internal space for better heat dissipation of the camera 15.

[0027] The two cameras 15 in the same group are positioned facing different directions. In this embodiment, the optical axis of the camera 15 on the gate side is offset from the lane at an angle of 15-45 degrees, preferably 30 degrees. Understandably, this angle can be adjusted according to actual needs and can be less than 15 or greater than 45 degrees; the specific value is not limited. The camera 15 on the side away from the gate is offset in the opposite direction at a certain angle, and the two cameras 15 form an overlapping area to ensure no blind spots.

[0028] When a vehicle approaches, a first signal is generated when it enters the field of view of any camera 15 in the same side camera group and its license plate is successfully recognized, and the gate 20 opens. The vehicle can then continue forward and pass through the gate without stopping. When the vehicle enters the field of view of the inner camera group and is recognized again, a second signal is generated, and the gate closes.

[0029] In summary, this utility model's solar-powered license plate recognition integrated machine integrates multiple cameras 15 into one unit, covering a wide recognition area of ​​two-way lanes without the need for additional poles. It features a compact structure, simple installation, and effectively solves the problem of recognition failure caused by vehicle position deviation, significantly improving traffic efficiency. Furthermore, its equipment cost, construction complexity, and overall cost are lower than traditional equipment. In addition, the large-area coverage of the solar panels on the outer surface of the main unit 10 and the top-tilting solar panel 12 structure enable self-sufficiency in electricity. This utility model is highly practical and has significant potential for widespread application.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
