Smart parking refers to the integrated application of technologies such as GPS positioning, mobile terminals,license plate recognization,parking reservation and wireless communication to the query, reservation, collection, navigation and management services of urban parking Spaces, so as to realize the integration of real-time query, update, navigation services and reservation of parking Spaces, to maximize the utilization rate of parking Spaces, improve parking profits, and optimize parking services for car owners.

1.Mobile terminal technology refers to the technology used in mobile devices (such as smartphones, tablets, wearables, etc.). These technologies include mobile application development (such as iOS and Android application development), mobile operating systems, mobile network technology (such as 4G, 5G), mobile user interface design, mobile device management, mobile security, etc. The development of mobile terminal technology enables people to access information, communicate, entertain and work through mobile devices anytime and anywhere.

2.Wireless communication technology refers to the technology of data transmission and communication through wireless transmission media such as radio waves or infrared rays. These technologies include cellular network technology (such as 4G and 5G), Wi-Fi technology, Bluetooth technology, infrared communication technology, etc. Wireless communication technology enables people to communicate and transmit data in real time without physical connection, which is an important part of modern communication field.

3.GPS (Global Positioning System) technology is a satellite navigation system consisting of a group of satellites and ground stations used to determine the precise position of any location on Earth. By receiving signals from different satellites and calculating their position, the GPS receiver can determine the specific location, speed and time of the receiver. GPS technology plays an important role in navigation, map service, traffic monitoring, weather forecast, scientific research and other fields, becoming one of the indispensable tools of modern society.

4.License plate recognition technology is a technology based on image processing and pattern recognition, which is used to automatically recognize and extract the license plate number on the vehicle. This technique typically utilizes computer vision and deep learning algorithms to locate, segment and recognize license plates in vehicle images. License plate recognition technology is widely used in intelligent transportation systems, parking management, security monitoring and other fields, which can improve work efficiency, strengthen security monitoring and improve the level of traffic management.

5.Parking reservation technology is a method of pre-booking a parking space through an app or system. The technology uses sensors and real-time data to detect the availability of parking Spaces and allows users to book them through a mobile app or online platform. Through parking reservation technology, users can plan their parking in advance, avoiding time wastage and the trouble of finding a parking space. This technology is becoming increasingly popular in urban parking management systems and parking lot management to improve parking efficiency and user experience.

In general, the intelligent parking system allows the owner to store the specific information of his vehicle including the parking lot, license plate number, vehicle model and parking reservation time and other important information into the intelligent parking database anytime and anywhere through the mobile terminal technology. The intelligent parking management system saves the user's request information into its reservation system. The booking agency of the parking management system is then individually communicated with the specific user, and the owner can view their booking time status and other information on their mobile device. Then through gps technology sensors in the mobile device owners can know their location and the location of various parking lots in the city, and via Google Maps to reach the most suitable parking lot. Through the license plate recognition system, a photo of the license plate is taken through a camera used at the entrance, which is then stored in a database. When the car enters the parking lot door, the license plate recognition system automatically recognizes the license plate number and passes the booked vehicle.
