With the development of society, the progress of technology and the vigorous development of Internet technology, more and more parking lots use intelligent devices to improve management efficiency through access to the Internet. The traditional parking lot system can no longer meet people's needs because of personnel cost and management efficiency. Parking lot managers have transformed and upgraded the traditional parking lot system one after another. At present, the traditional parking lot management system is prone to congestion at the entrance and exit of the parking lot during the rush hour. The traffic efficiency is very low, followed by the simple function of the system. It only plays the role of one car and one gear in the parking lot, and does not have the functions of helping car owners find parking spaces, find cars and pay fees quickly. The adopted manual charging also faces problems such as fund loopholes, card collection and change. Through LAN communication, it is necessary to install an independent database and front-end display in the parking lot during installation, and the client software is installed and run on the front-end display, which is not only large quantities and time-consuming, but also poor system scalability and maintenance. In contrast, the intelligent parking lot management system adopts the full-automatic computer management mode. From the exit of the parking lot to the road gate and then to the management center, all use the automatic control of the computer, which is very convenient for management, and the vehicles enter and leave the parking lot very quickly. In addition, it can easily realize unattended operation at the entrance and exit and automatic charging, which can greatly save the cost. Therefore, the intelligent parking lot system that can meet the needs of managers and car owners has very high potential and broad development prospects in the future. The transformation of traditional parking lot system can adopt advanced license plate recognition technology to clearly capture vehicle information and character images, so that car owners can pass in and out of the parking lot without stopping. It can also monitor the operation status of all online equipment, realize equipment fault pre discovery, self repair, real-time query of various report functions, and provide customers with a variety of pictures to query the on-site situation. It has the ability to query the charging amount in real time. The system breaks through the regional restrictions and realizes the remote management throughout the country. The car park charging system adopts automatic toll collection. It supports the popular mobile payment (Alipay, WeChat) owners who can pay app scan or login special parking APP to pay. The whole process is fast and convenient.
