英文文献原文Based on the GPS， GPRS， GIS and Internet vehicle positioning systemAbstractThis paper introduces an integrated geographic information system （ GIS ） , combined with the application of global positioning system （ GPS ) ， general packet radio service （GPRS） and Internet vehicle positioning system。 For a need to study and management of vehicle positioning of the enterprise ， choose a suitable vehicle positioning system is very important 。 The main feature of the system is the use of open geographic information system platform to access to resources, using the Internet based user interface, realization of vehicle positioning information update 。 The system consists of GPS based positioning device of the vehicle ， communication server, web server, database server and desktop map composition。 Positioning device installed in the vehicle interior， through the GPS position to collect real—time information ， the information is transmitted to a central database through GPRS。 The user can through the Internet in real-time show the location of each vehicle ， and then for all vehicles management。 Vehicle position and other related information will be displayed in the desktop map generated by an electronic map. This system is the use of information and communication technology combined with each other and form。 The sharp rise in fuel prices, this system was successfully used on a company’s resources for effective management of great help.Key words ： the global positioning system(GPS), general packet radio service （ GPRS ） ， vehicle positioning ， desktop map ， Internet ， information communication technology.1、Introduction：This vehicle positioning system the integrated use of modern in...
