License plate recognition integrated machines are widely used in parking lots, highways, entrances and exits, logistics parks and other scenarios. The algorithm is constantly improved and optimized to adapt to the license plate recognition needs of different scenarios and improve the stability of the system.
[0003] The current license plate recognition integrated machine technology can achieve long-distance locking and recognition in daytime conditions, but it is difficult to achieve long-distance accurate recognition in dim light conditions. Often, the vehicle cannot be released because the license plate recognition integrated machine cannot quickly recognize the license plate, resulting in vehicle congestion. The existing technology improves the long-distance recognition of the license plate recognition integrated machine by adding radar recognition equipment or increasing camera focal length technology. Improving camera focal length technology still has certain difficulties for long-distance recognition in dim light conditions. For this reason, we propose a license plate recognition integrated machine based on long-distance recognition.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] See also Figure 1-7 A license plate recognition integrated machine based on long-distance recognition includes a license plate recognition integrated machine body 1, a display screen 2, a camera 3 and a lamp 4. The display screen 2 is installed on a vertical surface of the license plate recognition integrated machine body 1, and the camera 3 is installed on the top horizontal surface of the license plate recognition integrated machine body 1. The cylindrical end of the camera 3 lens housing is fixedly and symmetrically connected to two camera housing connectors 6, and the end of the camera 3 lens housing is coaxially connected to one end of the lamp 4.
[0030] Furthermore, the lamp 4 includes a lamp connector 5, an annular lamp holder 8, a corrugated focusing glass 11 and a light strip 13. The annular lamp holder 8 is an annular structure with an L-shaped cross-section. One end of the lamp connector 5 is coaxially fixedly connected to the inner circle of the plane of the annular lamp holder 8, and the other end of the annular lamp holder 8 is flush with one end of the lamp connector 5. A light strip 13 is provided on the horizontal plane of the annular lamp holder 8 between the annular lamp holder 8 and the lamp connector 5. A corrugated focusing glass 11 is provided above the light strip 13 and is coaxially connected to the annular lamp holder 8. When the light strip 13 is energized and illuminated, the raised inclined surface of the corrugated focusing glass 11 will reflect the light at the inclined surface angle, and the reflected light is concentrated in a small range to concentrate and enhance the light.
[0031] Furthermore, at the other end where the lamp connector 5 is connected to the annular lamp holder 8, two lamp buckles 7 are provided on the cylindrical surface of the lamp connector 5. The two lamp buckles 7 are symmetrical about the origin of the lamp connector 5. The position of the lamp buckle 7 corresponds to the position of the camera housing connector 6. The camera housing connector 6 is buckled and connected to the lamp buckle 7. When connecting the lamp, the symmetrical camera housing connector 6 is inserted from the end where the lamp buckle 7 is connected to the end face. After rotating the lamp, the camera housing connector 6 is just stuck in the place where the lamp buckle 7 is not connected to the end face.
[0032] Furthermore, a light strip wiring hole 9 is opened on the horizontal plane of the ring-shaped lamp holder 8, and a light sensor 10 is connected to the ring-shaped lamp holder 8 and is connected to the internal light strip 13. The wiring between the light strip 13 and the power supply passes through the wiring hole 9, and the light sensor 10 is connected to the relevant electrical components inside the light strip 13. The light sensor 10 senses the external light to turn on or off the power.
[0033] Furthermore, at the other end of the annular lamp holder 8 that is fixedly connected to the lamp connector 5 , the end face of the annular lamp holder 8 is coaxially fixedly connected to a slot 12 of a semicircular arc ring, and the slot 12 serves as a limiting and fixing function.
[0034] Furthermore, a blue glass 14 is provided in the slot 12 and connected to the slot, and a semi-arc glass piece 15 is fixedly connected to the remaining cylindrical surface where the blue glass 14 contacts the slot 12. The semi-arc glass piece 15 and the slot 12 just butt together to form a complete arc, enclosing the blue glass 14.
[0035] Working principle: When the light is dim, the light strip 13 is energized through the light sensor 10, and the light emitted by the light strip 13 is concentrated through the corrugated focusing glass 11 to enhance the brightness. The light continues to pass through the blue glass 14 and finally emits blue concentrated light. Under dark conditions, the blue light will make the blue license plate reflect stronger light, which is convenient for the license plate recognition all-in-one machine to accurately identify the license plate at a long distance; when the lamp needs to be replaced, the camera housing connector 6 can be easily slid out of the lamp buckle 7 by rotating the lamp, and the same operation is performed during installation; when replacing the blue glass 14, the blue glass 14 can be easily pulled out by pulling out the semi-circular glass piece 15, and the semi-circular glass piece 15 also has certain waterproof and dustproof functions; in addition, the color of the blue glass 14 can be changed to accurately identify a specific driving lane at a long distance.
[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
