Description

Technical Field

[0001] The utility model relates to the technical field of license plate recognition, in particular to a dual-position license plate recognition device. Background Art

[0002] The barrier is an indispensable part of the parking system, helping to manage the orderly entry and exit of vehicles in the parking lot. It is mainly classified into straight-arm barriers, curved-arm barriers, fence barriers, anti-collision barriers, etc., and is widely used in parking lots and communities. The existing license plate recognition devices are all one-way license plate recognition, and some smaller parking lots can only open one entrance and exit due to the surrounding environment. At this time, the one-way license plate recognition device is very inconvenient to use.

[0003] After searching, the patent with announcement number CN214752262U is found: a two-way license plate recognition device, including a camera and a host. There are two cameras and they are installed in reverse. The camera is covered with a protective shell. There are rain shielding eaves and protective windows above the protective shell. There are two protective windows and they correspond to the positions of the cameras. A cooling fan and a cleaning mechanism driven by a motor are installed on the protective shell. The cooling fan and the cleaning mechanism correspond to the positions of the protective windows. A temperature and humidity sensor is installed on the protective shell. By installing two cameras and setting them in reverse, two-way license plate recognition can be realized, which meets the use requirements of small parking lots. The protective shell on the camera can be used to control the camera externally. The protection of the camera body can reduce the risk of damage, the rain shield can prevent rain, the protective window can meet the shooting needs of the camera, and the cleaning mechanism can clean the accumulated water on the protective window, so that the camera still has a high recognition rate on rainy days; the cooling fan can optimize the heat dissipation effect of the camera to avoid the high temperature in the protective shell that reduces the service life of the camera. However, in actual use, the device cannot automatically adjust the angle of the camera. If the vehicle license plate cannot be recognized due to height, manual assistance is required. Since there are many unmanned parking lots, congestion in and out will be caused. For this reason, the present invention proposes a dual-camera license plate recognition device.
