Intelligent Vehicle Monitoring System Based on GPS, GSM and GIS

To meet the requirements of some intelligent vehicle monitoring system, the software integrates Global Position System (GPS), Geographic Information System (GIS) and Global System for Mobile communications (GSM) in the whole. The structure, network topology, functions, main technical features and their implementation principles of the system are introduced. Then hardware design of the vehicle terminal is given in short. Communication process and data transmission between the server and the client (relay server) and client through TCP/IP and UDP protocol are discussed in detail in this paper. Testing result using LoadRunner software is also analyzed. Practice shows the robustness of the software and feasibility of object-oriented programming.
