The invention belongs to the technical field of parking lot management, and particularly relates to a lifting type license plate recognition control system. The system comprises a processor, and the processor is electrically connected with an ultrasonic ranging module, a double-rotating-motor driving module, a loudspeaker and a parking lot server, wherein the parking lot server is further electrically connected with a high-speed camera, the ultrasonic ranging module is used for detecting a vehicle distance signal and sending the vehicle distance signal to the processor, the processor comparesthe vehicle distance signal with a preset value and sends a control signal to the double-rotating-motor module, the processor is further used for sending a prompt signal to the loudspeaker for voice prompt, and the high-speed camera is used for acquiring a vehicle rear license plate image and sending the vehicle rear license plate image to the parking lot server for analysis and storage. The system is high in identification precision, simple in system framework and low in use cost.
Description
technical field [0001] The invention belongs to the technical field of parking lot management, and in particular relates to a lifting type license plate recognition control system. Background technique [0002] Most of the traditional license plate recognition relies on the traffic camera inside the parking lot, which also has the tasks of monitoring and license plate recognition. When the traffic flow in the parking lot is large, it cannot effectively and accurately recognize the license plate, and some special license plate recognition cameras are often installed on the top of the parking lot. , but also because the speed of the vehicle in the parking lot is fast and the recognition distance is not enough, it will cause the problem of inaccurate recognition, and it will bring difficulties to the maintenance of the camera. At the same time, some existing license plate recognition systems have complex structures and high cost of use. Contents of the invention [0003] In o...
