【摘要】 短消息是GSM(全球移动通信系统)中最简便的数据通信方式。随着短消息业务的日益完善,短消息已具备承载重要数据信息的能力。文中探讨了利用GSM短消息作为数据传输媒介实现远程监控的可行性,给出了采用西门子公司的TC35型GSM收发模块和AT89C51单片机构成远程监控通信单元的设计方案,并详细介绍了远程监控通信单元的硬件和软件设计。更多还原

【Abstract】 Short message service(SMS) is the most simple and convenient mode of data communication in GSM system. Recently, as a new information service SMS is developing rapidly. With the continuous improvement of SMS, SMS has been provided with the capability of bearing important data. This paper discusses the possibility of using short message service through GSM to implement remote monitoring, then a design scheme consisting of TC35 GSM Transceive module of Siemens and AT89C51 monolithic processor is given. The hardware and software design of remote monitoring communication unit is also discussed in detail. This design philosophy can also be used in the domain of high real-time requirement.更多还原
