This parking lot charging system is based on ETC technology and belongs to high-end intelligent parking lot. It is composed of three parts: entrance and exit control system, data management center and video monitoring system. High degree of intelligence and automation. Here, our electronic label (OBU) adopts the 5.8GHz microwave band. The reading and writing equipment of OBU is the microwave antenna RSU. The parking lot can use the dual interface CPU card and IC card as the vehicle management pass card. Fixed vehicles can quickly enter and exit the parking lot without stopping and pay automatically. Temporary vehicles can enter and exit with IC card. The main function of video monitoring system is to monitor and record the parking lot and ensure the safety of the parking lot. Next, I will analyze the specific system architecture. 1ã Entrance and exit control system the entrance and exit control system consists of entrance management, exit management and communication. Here, we use TCP / IP communication protocol to be responsible for data transmission between entrance and exit and management center. As we all know, TCP / IP protocol has the advantages of convenient expansion and fast speed, which can meet the networking requirements and response speed of the parking lot. In terms of entrance and exit management, we install microwave antenna RSU next to the entrance and exit lane to identify, read and write electronic labels. Vehicles equipped with dual interface CPU card electronic labels directly enter and leave the parking lot without parking and pay automatically. Temporary vehicles enter the parking lot with dual interface CPU card or IC card, and they need to pay by card when they leave the parking lot. 2ã Data management center data management center consists of server, communication equipment (such as switch, router, etc.) and management software. The main function is to manage data, such as backup, recording, IC card management, system parameter setting, generation of various data reports, black-and-white list, monitoring data, etc. 3ã Video monitoring system video monitoring system we use network monitoring camera, which can be directly connected to the existing TCP / IP communication protocol in the parking lot without converter. The network camera has the characteristics of simple and practical installation. By arranging cameras at each entrance and exit and each area of the parking lot, managers can understand the dynamics of each entrance and exit in real time on the computer through the network. The above is the system structure of intelligent parking lot system based on ETC technology. From the above, we can see that this parking lot system is mainly used in places with more fixed users and higher requirements for parking lots, such as high-end communities, buildings, units, etc.
