摘要
简述GPRS技术要点,提出基于GPRS的微处理器无线上网的解决方案,即在微处理器中实现PPP协议,通过串行接口驱动无线modem经GPRS无线网络连接到Internet,并介绍硬件和软件系统的设计方法。这种新型的微处理器无线上网方案使得分布于在边远地区或移动系统中的微处理器无需有线网络即可接入Internet,实现数据传输。
This paper introduces the characteristics of GPRS technology in brief and presents a wireless scheme of connecting microprocessor to Internet based on GPRS. The PPP protocol is implemented in the microprocessor. Then the microprocessor drives the wireless modem through serial interface to connect with Internet with the help of GPRS network. The design method of its hardware and software system is presented. The wireless scheme is extremely fit for the applications of sampling and monitoring system, which lies in remote region or mobile objects.
