摘要：随着科技发展，汽车智能化和无人车已经成为研究方向和将来发展趋势。这也使得无人车的定位技术需求越来越高。为了解决这个问题，则需设计出一个能够对目标进行准确定位且能够实时快速传输数据至客户端的系统服务器。本文介绍GPRS无线通信技术、差分GPS定位技术以及串口通信技术这三种技术的相关知识，通过结合这三项技术设计出一个基于GPRS技术无人车辆DGPS定位系统服务器系统。这个系统服务器是运用C#语言在Visual Studio。NET平台上进行开发设计的，设计完成的服务器能够与客户端进行Socket通信；通过串口接收差分GPS报文获得准确的定位信息以及对客户端登录登出信息和在此期间进行的数据通信量记录统计。82734

The design of server system which locate unmanned vehicles based on GPRS and DGPS Title

Abstract With the development of science and technology, automobile intellectualization and unmanned vehicle has become a research direction and trend of development in the future。 This result in the requirements of unmanned vehicle positioning technology should be improved。 In order to solve this problem, we need to design a server system which can locate the target accurately and transmit data to the client fast in a short space of time。 This paper introduced the General Packet Radio Service, Differential Global Positioning System and serial communications, to design a server system which can locate unmanned vehicles by the combination of technology。 The server system is designed in Visual Studio。NET Framework development platform with C# programming language, that is able to communicate with the client based by Socket, receives differential GPS information by means of serialport as well as record the information of every client login or logout of the sever and the amount of data which is transmited between sever and client during this time。
