摘要
GPS的广泛应用,将GPS应用到工程预警中有着重要的意义,文章主要探讨了GPS终端在预警系统中利用GPRS技术接入网络,从而实现多方外业采集数据实时回传的技术方法,保证预警系统的实时性。本文将数据交换系统分为三个部分,首先是外业GPS终端,通过串口从OEM板获取实时的二进制GPS观测原始数据;第二是服务器终端,服务器端采用多线程技术实现并行实时获取外业数据;最后是数据通讯,利用GPRS技术将外业终端和服务器连接,并实现两者的数据交换。本文最后通过程序实现,数据设备测试,验证该数据回传系统的可行性。
With the widely use of GPS ,GPS become more and more important in engineering warning ,this paper mainly discusses the application of GPS in large equipment collision warning system .the GPS uses GPRS to access Net-work,so the server can get the field GPS data real-time to ensure warning real-time. This article divides the data ex-change system into three parts ,the first is the GPS terminal ,through the serial port to obtain real-time GPS observations of the binary raw data from the OEM board;second is the server terminal ,server uses multi-threading technology to a-chieve parallel real-time receiving data;finally is the data communications ,using GPRS technology to connect terminal and server,and to achieve data exchange between the two .Finally,through the program,data equipment testing,valida-tion of the data returned feasibility of the system .
