The Central Software Designing Of Vehicle Supervisory Scheduling System Based On GPS/GIS/GSM/GPRS

Along with the developments of Wireless Communication, Geography Information Technology,GPS Localization Technology as well as a requirement of social economic development the GPSVehicle Localization Supervisory System has been used widely in applications just like intelligenttransportation, logistics and monitoring and dispatching of special vehicle. Moreover it brings lots ofeconomic and social benefits.Through the deep research about GPS Vehicle Localization Supervisory System and other relativetechnologies the Vehicle Localization System arises in this paper, which based on GPS, GIS, GSM andGPRS. Additionally, this system is a successful combination of SMS and GPRS communication, whichmake a significant achievement that the central monitoring and dispatching system can receive the datain both two kinds of styles. According to the fact that the system is based on C/S structure, a servermiddleware module is inserted in the system by which the communication with the vehicle-borneterminal is carried out. At the same time a higher communication protocol is formulated between themiddleware and customer terminal. Regarding to the protocol the vehicle information is encapsulated asecond time in a unified way by the server middleware. It only needs to add an analysis module of thenew communication protocol in the server middleware to make sure that the customer terminal systembegins to work properly without or only a little modifying when a new terminal product using a newcommunication protocol is in. The way of solution above mentioned not only makes the interfaces ofmany different kinds of terminal products to be convenient but also improves the efficiency ofdeveloping the system greatly and cuts the costs apparently.At present the system has been applied widely in the trade of tobacco, insurance and materialtransportation. In conclusion its stability and reliability have been approved by the customers because ofthe great benefits it makes.
