基于Socket的GPRS远程数据采集方法

Research of GPRS Remote Data Acquisition Method Based on Socket

C/S模式的信息管理系统,常常在一个局域网络环境下实现,服务器和客户机的IP地址是固定的,这样的数据传输可以通过ODBC驱动和静态TCP/IP协议来实现。通过GPRS网络环境中提供的远程数据操作服务,实现了服务器IP地址是固定的和客户机的IP地址是变化的C/S远程数据采集软件。在对GPRS网络和Win-dows Socket通信原理的分析上、建立了动态IP链接的体系结构。并对GPRS网络远程数据采集的Delphi实现方法进行了较为深入的探讨。

The MIS systems of C/S mode are often carried out in LAN,in which the IP address of the servers and client are immobile.The data can be transmitted at the base of the implementation of ODBC and the protocol of TCP/IP.The authors empolder the software of remote data acquisition whose IP is variable.On the foundation of the analysis of GPRS network and the theory of Windows Socket,the system structure of dynamic IP link is established.At the end the way of remote data acquisition using Delphi is discussed.
