Research on GPRS vehicle location network service system

We can achieve vehicle location tracking on Internet by using GPRS vehicle location terminal and combining with Internet technology and GIS technology. The article gives the design structure of GPRS vehicle location network service system. The system is divided into three parts: GIS network workstations, network communications server and GPRS vehicle location terminal. Then, the article makes the brief introduction to the function of three parts of the system: GIS network workstations are responsible for sending command "Setting GPS Location Data Return Interval" to network communications server, and receiving GPS location data packet uploaded from GPRS vehicle location terminal from network communications server, making analysis of received GPS location data packet; The vehicles will be appeared as title in the specified position on the map by combining with GIS. Network communications server is responsible for receiving the command “Setting GPS Location Data Return Interval” from GIS network workstations and transmitting to the specified GPRS vehicle location terminal and receiving GPS location data packet pass backed from GPRS vehicle location terminal and distributing to the appropriate GIS network workstations simultaneously. GPRS vehicle location terminal is responsible for receiving the command “Setting GPS Location Data Return Interval” sent from network communications server and sending GPS location data collected by GPS module to network communications server. Finally, the article tests the feasibility of system design through experiment. By using the system, it will be easy and fast to make vehicle location tracking on Internet and timely access vehicle location information.
