摘要
GPRS是一种基于GSM系统的无线分组交换技术,提供端到端的、广域的无线IP连接,具有高速、永久在线等特点。文中分析了构建基于GPRS监控系统的4个难点,提出外网方式和内网方式的解决办法。还讨论了以GPRS内网方式构建监控系统存在的问题及其解决方案,具体介绍了一套基于GPRS无线监控系统的设计实例,并对其应用前景进行了展望。
GPRS is a wireless packet switching technique based on GSM system,it provides point to point wireless link using IP protocol in wide area,it possesses the advantages of high rate,always on-line etc.this paper analyzes four implementation difficulties of constructing a GPRS based monitor system,and puts forward some effective solving methods which are SM-MH,DH-MH and MH-MH as well.The problems and corresponding countermeasures are discussed when the monitor system with GPRS MH-MH was constructed.Finally,this paper introduces a realized GPRS based wireless monitor system,and presents its application prospect.
