摘要

 当今时代，移动通信飞速发展，GPRS(通用无线分组业务)已为大多数人们所熟悉。GPRS是在现有GSM系统上发展出来的一种新的承载业务，目的是为GSM用户提供分组形式的数据业务。远程监控系统是许多重要场所诸如电力、邮电、银行、交通、商场等需要信息广泛交流企业的生产与管理的必备系统。传统远程监控系统的实现方式一般都需要自己建设并维护有线或无线网络,维护费用高,通信距离有限。随着通信技术的发展,原有的远程监控系统已经日益不能满足多方面的要求,我们需要实时性更高,通信距离更远,成本更低的通信方式,本文就此提出了一种基于GPRS的远程数据传输系统，着重以监控系统为应用对象。该系统由三星ARM芯片S3C44BOX作为微处理器，ARM软件使用uC/OS操作系统，Q2406作为GPRS模块，ARM芯片和GPRS模块之间用串行口进行通信。

Abstract
The contemporary era, rapid development of mobile communications, GPRS (General Packet Radio Service) for the majority of people are familiar with. GPRS is the existing GSM system developed a new bearing business, aims to provide GSM users in the form of packet data services. Remote monitoring system is important in many places, such as electricity, telecommunications, banking, transport, shopping malls and other businesses need extensive exchange of information production and management systems required. Remote Monitoring System traditional way to achieve the general need to build and maintain their own wired or wireless network, high maintenance costs, limited communication distance. With the development of communication technology, the original remote monitoring system has become increasingly unable to meet various requirements, we need real-time higher and farther the distance, lower-cost means of communication, the paper put forward a GPRS-based Long-distance data transmission system, to focus on monitoring system for the application object. The system from Samsung as the ARM microprocessor chip S3C44BOX, ARM software uC / OS operating system, Q2406 as a GPRS module, ARM chip and between GPRS module with a serial port communications.
