摘要在企业信息化的今天，效率决定成败，企业内沟通的及时性直接影响企业的运作效率，如何在节约成本的同时提高沟通效率是摆在众多企业面前的一大难题。在网络日益普及的今天，网络信息传递作为一种方便快捷的通信手段，已经成为企业和行业人士日常工作不可或缺的工具。在单位员工工作比较分散或单位事务比较多的企业，网络信息传输系统已经成为必不可少的通信工具。
与此同时，尽管3G，4G网络已经出现，但从其经济性角度考虑，并不适用于小型企业数据传输系统。因此，GPRS移动通讯方式因具有覆盖范围大，实时性好，免网络维护等优点，在分布范围广，数据采集点多，实时要求性高的场合十分合适。 65009
本文就是以GPRS移动通信网络作为远程数据的传输平台，开发一个企业数据网络传输管理系统。主要利用VB编程软件和GPRS无线传输模块实现网络信息远程无线传输和系统设置等功能。

Title The design and realization of enterprise data transport network management system based on GPRS
Abstract
Efficiency has become a decisive role on the success of a company as information has been rapidly developed around the world. And, one important factor of company’s efficiency is to communicate timely and effectively. Along with the popularization and rapid development of Internet, transmitting information through internet has become an indispensable communication mean to many companies in their daily work.
Meanwhile, although 3G and 4G internet has been widely used in daily life, it is not suitable for most small-scale companies owning to its high economic cost. While GPRS can be a good choice due to its advantages such as wide coverage of wireless signal, excellent real-time performance and so on.
This article is aim to develop an enterprise information transmission and management system through the platform of GPRS mobile communication network. VB programming software and GPRS wireless transmission module have been mainly used to realize the function of remote wireless transmission, system settings and so on.
Keywords GPRS Module Server/Client Model TCP/IP Protocol
