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。本文以数据采集与监视控制系统(SCADA)为对象,阐述了利用GPRS通信网络实现自动数据采集与RTU实时监控数据传输的可行性,以及在此基础上针对电力系统实际应用环境的安全功能。提出一套基于GPRS无线监控系统的设计范例,分析了GPRS技术在电力系统中应用的优势和缺点,并对其应用前景进行了展望。
GPRS （General Packet Radio Service）is a wireless packet switching technique based on GSM system. It provides point to point wireless link using IP protocol in wide area and possesses the advantages of high rate , always on-line etc. Taking the power SCADA （Supervisory Control And Data Acquisition） system as the object, the paper elaborates the feasibility of automatic date collection and RTU real-time monitoring data transmission by the GPRS correspondence network as well as the security function of electrical power system in the practical application environment. Finally, a practical GPRS model based on wireless monitor system is proposed and we analyses its advantages and shortcomings in the power system, and presents its application prospect.
