Research And Implementation Of The Vehicle Management System Based On WEBGIS

As Intelligent Transportation System develops positively, logistics enterprises, the forerunners of the traffic transportation are applying the scientific developing concepts to industrial development. To satisfy consumers'request of high information transparence, the logistics companies need get the goods transportation's real time information, solve goods tracking problems, and realize reasonable dispatch. However in the condition of lacking technologies, these problems are hard to solve. Currently the most feasible method to solve the problem of logistics transportation management is the vehicle management system developed by GPS accurate positioning technology and GPSONE wide coverage communication technology. Therefore, the study and development of the vehicle management system has large realistic significance, and it's also one of intelligent transportation system's core studying subjects.What this subject studies is to use CDMA mobile communication network as communication media, combine the global positioning technology with vector geographic information electronic map software platform, develop vehicle management system based on the internet. This system comes out from the combination of the global positioning technology, computer network technology, database technology, geographic information technology and communication technology. It discards the traditional car carrier positioning terminal mode of GMS/GPRS/CDMA+GPS, and has the merits of large coverage, widely adaptation, low cost.This thesis deeply discusses the involving key technologies of vehicle management system based on the Internet, global positioning technologies, geographic information technology and mobile communication technology. On such bases, it analyses the overall architecture of the vehicle management system and studies all kinds of function modules'fundamentals and applications.By the platform of WEBGIS and the methods of object-oriented analysis,the system mainly discusses the software architecture designing of the whole vehicle management system, produces a set of integral solutions based on the mode of the browser/server. It accomplishes the functions of monitoring the moving objects'positions, alarm to abnormity, playing back to historical data, verifying the cars rapidly, and so on. Meanwhile, it expounds how to design and realize the function modules of central database and electronic maps.Finally, combining the current technology developing trend and more programming technology's application, the thesis puts forward new solutions and provides wider prospect for logistics transportation management.
