Working Principle of Unmanned Parking Lot System Based on License Plate Recognition Technology

Every wisdom experience is because someone simplifies complex processes and profound principles and applies them to life, bringing convenience to people's life. The parking management system applies advanced technologies such as mobile payment, license plate recognition, big data and cloud computing to the parking ticket machine system to make people's travel smoother. Intelligent parking management system seems simple, but the technical implementation is not necessarily simple. As a manufacturer of parking lot system, it is necessary to briefly describe the working principle of parking lot system based on vehicle identification technology. System working principle: Vehicle admission recognition process when the vehicle arrives at the entrance, the ground induction coil detects the signal, starts to capture it with the main camera and auxiliary camera, and the video license plate recognition software automatically recognizes the license plate number and displays it on the screen. For vehicles whose license plates cannot be recognized, the system sends the vehicle information to the correction system of the parking lot cloud platform for processing and stores the correction results. The entrance gate is automatically picked up, and the owner drives into the parking lot. After ensuring the normal entry of the vehicle, the entrance gate automatically falls down, and the parking lot automatic toll management system starts to stop the vehicle. Working principle of the system: vehicle exit payment process when the owner is ready to drive out of the parking lot, he can make self-service payment through self-service payment or a third-party platform. When the vehicle drives to the exit of the parking lot, the exit intelligent vehicle detector detects the signal of the ground sensing coil, which triggers the main camera and auxiliary camera at the exit of the parking lot to capture. The video recognition software automatically recognizes the license plate number, and the parking fee management system automatically settles the payment amount, and determines whether the vehicle has paid the fee or whether it is free parking for members. If yes, the system will automatically control the exit gate to open and release the vehicle; If not, the owner needs to pay by scanning or entering the third-party platform. The vehicle can be released only after the payment is successful. For vehicles that cannot be recognized, the personnel of the management center can manually capture and modify the license plate, or re recognize them through different algorithms on the cloud platform. After the correction is successful, the system will automatically settle the payment amount of the vehicle. The parking administrator can also know the use status of the whole parking lot in real time through the monitoring interface of the parking lot monitoring terminal. Each process involves various technical applications, such as license plate recognition, billing system, image processing, access control system, etc. However, each system has its own technical difficulties. By connecting each system and forming a set of multi-functional and seamless system, there will be parking lot systems with different functions, which is enough to meet different parking needs in the current society.
