The Design And Implementation Of Vehicle Monitoring And Navigation Based On GPS And GIS

With the constant development of urban traffic and transportation, its existing means cannot meet the demand of traffic and transportation management and service. An intellectual transportation system, a new kind of informationalized, intellectualized, and socialized modem traffic system, is rapidly developed by using advanced technology such as electronic, information, communication technology, etc. and by transforming the traditional traffic transportation and management system.The main purpose of this paper is to solve vehicle monitoring and navigation problems, and on the basis of which, to build a comprehensive vehicle administration system of vehicle alarm, monitoring and navigation. This system can be divided into two parts: vehicle controlling center and vehicle navigation module. The former, which is made up of central server, communication machine, switch and terminal controlling station, monitors the position and state of vehicle and shows its orbit on the electronic map. The latter, made up of GPS and portable PC on vehicle produces proper real time guiding orders with the help of map database and GPS location information to guide the driver to take the right route.All the software is developed by following the design thought, and the software project is designed according to the principle of abstraction and information concealment, module and part to design and implementation. The paper discussed the total design of the system, the constitution of the system's function module, the design and implementation of key technology. It achieved to deal with GPS vehicle navigation and supervisor control center, using projection match method to solve the position track of vehicle on electronic map when GPS information is lost.
