摘要
随着网络应用的普及和移动装备的大量增加,通过无线通信网络传输数据的这种方式在工业的应用越来越多。为了使远程距离的数据传输实现更灵活方便, GPRS 以一种新型移动数据通信业务,在移动用户和数据网络之间提供一种无线连接,给移动用户提供了高速无线数据通信业务,使用 GPRS 技术实现数据分组发送和接收,用户永远在线且按数据流量计费,大大降低了服务成本,因此此技术越来越多地应用到各种各样的场合中。其中就可以帮助企业开展各种增值业务,以减轻企业对这些繁杂业务的管理和资金的浪费。又如在许多的远程数据采集系统中,常常需要对众多监测点的数据进行实习采集和监控,同时大部分的监测数据需要实时发送到管理中心的后台服务器进行处理,这就需要一个高效、廉价、有效的传输系统,而GPRS信息远程传输系统就是这样的系统。
,通过GPRS模块,在GPRS网络中使用scoket套接字编程计生局和FTP协议完成本地嵌入式平台与远程FTP服务器通信,在GSM网络中通过AT指令与手机发送文本短消息,从而实现实时无线数据传输功能。

Abstract
With the popularity work applications and the proliferation of mobile equipment, data transmission through work in industrial applications of more and more this way. In order to make the remote distance data transmission to implement a more flexible, convenient and GPRS to a new type of mobile munication service, between mobile users and the work to provide a wireless connection, provide mobile users with high-speed wireless munication service, use GPRS technology to realize data packet to send and receive, user online forever and charged according to the data flow, greatly reduce the service cost, so this technology is increasingly applied to all kinds of situations. Which can help enterprises to carry out various value-added services, to alleviate the enterprise the management of the multifarious business and waste of money. And as in many of the remote data acquisition system, often need to many internship through the data acquisition and monitoring, monitoring points at the same time, most of the real-time monitoring data needs to be sent to management center of the background server processing, which requires an efficient, inexpensive and effective transmission system, the GPRS remote information transmission system is such a system.
Remote information transmission system in embedded operating system there and S3C6410 with ARM11 as the core processor a
