Taking the first professional GPS long-distance passenger vehicle management system in China, the Yaxun long-distance passenger GPS intelligent management system, as an example, it combines satellite positioning technology, GPRS/CDMA communication business, GIS technology, image acquisition technology, computer network, and database technology to establish a master control (combining C/S structure and B/S structure) in the passenger transportation company, while the others are set as sub control, The public security department and transportation management department, among other departments, establish a dedicated control center system. The system consists of four parts: the control center system, wireless communication platform (GPRS/CDMA), global satellite positioning system (GPS), and on-board equipment, forming a comprehensive platform for driver management and vehicle tracking 24/7 and all around the world; The system can implement dynamic tracking, monitoring, photography, driving records, management, data analysis and other functions on registered vehicles. The monitored vehicles can be displayed on electronic maps and saved with vehicle trajectory data; The operating terminal can freely select the internal LAN of the server or the international internet to access the center, and can provide an online comprehensive bus management data analysis and control system (B/S structure) through the IE browser; And the capacity of the system software can be expanded at any time according to the hardware configuration of the central server and operating terminal, with a maximum of 500000 vehicles. The connected vehicles can not only be long-distance passenger vehicles, but also social vehicles such as tourist vehicles. At the same time, the system can also adopt group management, where different types of vehicles are classified into different groups, making it easier for management personnel to operate.
