Intelligent car parking system is gradually replacing the traditional parking lot and becoming the mainstream of smart city with the completion of more and more mobile Internet intelligent parking management system projects in China, the payment of parking lot is slow for owners. Intelligent car parking system is gradually replacing the traditional parking lot and becoming the mainstream of smart city, which is not only the inevitable result of technological innovation in the parking industry, but also the general trend of smart city development. In a few years, the management of vehicle identity will basically transition to the "Internet" management stage. The intelligent parking management system will realize travel through the intelligent transportation sector, and will eventually become an important core part of the smart city, involving the work and travel of each resident. License plate recognition technology requires that the moving vehicle license plate can be extracted and recognized from the complex background. Through license plate extraction, image preprocessing, feature extraction, license plate character recognition and other technologies, intelligent license plate can recognize vehicle license plate, color and other information. At present, the new technology level is that the recognition rate of letters and numbers can reach 99.7%, and the recognition rate of Chinese characters can reach 99%. The travel control of license plate recognition system uses photoelectric switch to replace mechanical travel switch. 3.
