Vehicle Monitoring Systems Performance Improvement To Key Technologies

With the rapid development of economic, the quantity of vehicles increases rapidly, the scientific,standardized management of vehicles has become a hot social needs. In this case, vehicle monitoring system was Came into being. It contains GPS technology, GIS technology and wireless communication technologies, and can achieve the remote monitoring of vehicles, brings about efficient and facilitative management of vehicles. To the practical demands of project, a set of solution on the remote vehicle monitoring system based on GPRS / GPS / GIS was designed in this paper.The system was designed consulting the earlier development of the vehicle monitoring system of Nanjing University of Science & Technology, in the face of the background of the new project, analyzed the problem of the previous system, proposed solutions and applied to the design of the new system. The Main research in the thesis is the improved design of related function points of Monitoring Center of the Vehicle Monitoring System, including the design of database, the data-processing mechanism of the Data Service Center and the performance optimization of the Data Service Center. In the design of database, the data type XML was used to optimize the database, which enhanced the performance of data storage and data interpretation ; In the design of data processing unit of Data Service Center, analyzed the function of protocol parser ,focused on solving the data transmitted in the Data Service Center,data storage in the database,data processing and packaging and the management of the information sent to a vehicle; When researching into the performance of the Data Service Center, mainly solved the problem of Garbage Collection.
