The system consists of three parts: GPS vehicle terminal, mobile communication network and back-end server. The three parts use GSM wireless digital two-way communication and Internet data transmission. The GPS in-vehicle device automatically outputs the real-time working information of the vehicle and the GPS satellite positioning information according to the management instruction, and sends the information to the background server immediately; the control center knows the working state of the vehicle at any time according to the received related information, and at the same time, controls The actual location of the vehicle is displayed in real time on the electronic map of the center.
This system uses GPRS network networking. Install the database server and GIS map server in the monitoring center. In terms of security of the networking: the overall network access is implemented by virtual VPN technology, that is, the vehicle terminal client communicates with the background server through the GPRS network to obtain the vehicle location information. The wireless and wired links of this solution use VPN private network technology to achieve physical isolation from the Internet.
