Based On The Gprs / Gps Vehicle Location Monitoring System Design And Implementation

Integrated with GPS, GIS and the technology of database and communication, vehicle monitoring system is one of the most important part of ITS. As the importance of the vehicle management in logistics enterprise this article presents a GPRS-based vehicle monitoring system project which is designed according to enterprise needs and the principle of the vehicle management. It will bring the enterprise good vehicle management, high work efficiency and great cost saving.This article firstly describes the background and purport of choosing the thesis and expatiates the current status of the relevant technology accordingly. Based on analysis of company's requirement it put forward the framework of this system which is composed of three modules, vehicle terminal, wireless communication network and monitoring center. The terminal will receive and parse the GPS data. It consolidates the information of the vehicle's longitude, latitude, velocity, direction, time and status. Then it connects to internet by GPRS communication module and transmits the consolidated information to monitoring center. The communication server of the center will then receive the real time data from the vehicle terminal by connecting it through GPRS. After check and filtration the final valid data will be transferred to the monitoring terminal.Then the monitoring terminal will match the parsed vehicle information with the electronic map and dynamically show the right position of the vehicle on the map. The dynamic position data can be shown clearly, visually and timely so that the center can accordingly do vehicle patrol and running track replay, stop supply of gasoline and electric power, or call policy for the vehicles that overspeeding or being robbed. Also the monitoring terminal can be consulted for vehicle information as well as the surroundings on the map.
