Design And Implementation Of Vehicle Monitoring System

The development status and trend of vehicle system is firstly introduced.Each part of the system is detailed analysed in system design perspective, the basic function of each part is designed in this thesis. Comunication protocal of the sysytem is described and protocal of application layer is designed.The software of server side is divided into four modules(Display module,Database moudule,Communication Module and Control Module) based on modularization-devising method . Database module is implemented, using ACCESS as the database and ODBC as database access technology and one method of dynamicly load ODBC database source is putted forward .The main function of communication module is sending and receiving message, which is implemented using Socket. Control module is the kernel of the system , it can be divided into three modules , namely , communication connection module,Data format conversion module and monitoring message management module . Three modules works together to communicate and manage monitoring message.Application and implement of GIS (Geograhpic Information system) is expatiated as the emphases. Development procedure of MapX in VC is described. The implemental method of Eagle-eye Map using technology of view splitting is creatively proposed. Compared with other method, this one is more simple and more convenient to operate. Three kinds of control manner are used in vechile reappearance of track, namely, high speed, low speed, step by step. The clue of dispose the point using modularization-devising method is proposed.Experimental result shows system has realized anticipant basic function.
