Description

Technical Field

[0001] The present application relates to the field of license plate recognition, and in particular to an anti-collision protection device for a license plate recognition. Background Art

[0002] The license plate recognition system is an application of computer video image recognition technology in vehicle license plate recognition. License plate recognition is widely used in highway vehicle management. In electronic toll collection systems, it is also the main means of identifying vehicle identity in combination with DSRC technology. The terminal equipment in the license plate recognition system is the license plate recognition.

[0003] The Chinese patent with the announcement number CN217404997U discloses an anti-collision protection device for a license plate reader, including a road body, a detection structure, a license plate reader body, a support structure, a lifting structure, a buffer structure and a support shell. Support columns 1 and 2 are arranged on both sides of the road body. The support columns 1 and 2 are fixedly connected to the ground. An arc groove is arranged under the ground on the right side of the road body. The elastic force of the spring and the collision force offset each other, and the impact force of the collision is buffered and reduced. The support frame bears the remaining collision impact, which is convenient for protecting the license plate reader and avoiding the license plate. The identifier is damaged by a collision with a vehicle. In this application, the support ring block supports the support sleeve, and the support sleeve supports the main body of the license plate identifier, so as to ensure the stability of the license plate identifier and prevent the license plate identifier from tipping over. However, there are still some shortcomings in the existing device. When protecting the existing license plate identifier, a protective item such as an anti-collision plate is usually installed at the front end of the existing license plate identifier to protect the license plate identifier. The horsepower or impact force of the vehicle is large, so it is easy to hit the anti-collision plate, thereby causing the root of the license plate identifier to break. For this reason, we propose an anti-collision protection device for a license plate identifier to solve the above problem. Utility Model Content
