GPRS无线网络在远程数据采集中的应用

Application of GPRS wireless network in remote data acquisition

采用GPRS进行远程数据采集,可以借助其覆盖面大、通讯质量高等特点为那些涉及地域广、设备布局分散的监控点提供一种快速可靠的无线数据传输通道。首先分析了GPRS的特点和优势,然后讨论了用GPRS实现远程数据采集的组网方案,并对网络传输的可靠性进行了分析,最后给出了服务器端的部分程序片断。

Remote data acquisition using GPRS provides a sort of fast, reliable wireless data transmission channel for those watch stations which cover widely and distribute dispersedly with the help of the characteristics such as wide spread, high communication quality and so on. Firstly the characteristics and advantages of GPRS are analyzed. Secondly, the schemes of network organization to carry out remote data acquisition is discussed using GPRS and the reliability of network transmission is analyzed. Last the partial segments of the server in programme are provided.
