摘要
GPRS(通用分组无线业务)是一组新的非语音通信增值业务。它利用现有的移动电话网络发送和接收信息。本课题研究设计了一种基于网络技术的嵌入式GPRS无线数据终端,该GPRS无线数据终端在8位高性能嵌入式微处理器AT-mega128和实时多线程操作系统Nut/OS的基础上设计实现。该用户终端能以低廉、快速、可靠的方式连入GPRS网络和互联网,用户终端数据信息实时简洁传送。同时为用户终端安全稳定的运行提供了可靠的保证。
The GPRS （General Packet Radio Service） is a new nonvoice value added service that allows information to be sent and received across a mobile telephone network. We design an embedded GPRS wireless data terminals based on network-based technology, which is implemented in eight high-performance embedded microprocessors ATmega128 and real-time multi-threaded operating system Nut/OS. User terminal can be connected to GPRS networks and the lnternet in a cheap, fast and reliable way, and data can he simply and real-time transited, as well as the user terminal provides safe and stable operation of a reliable guarantee.
