摘要
无线专网是指目前国外流行的窄带移动数据通信系统。与传统移动通信系统的数据传输相比 ,无线专网具有低成本、高频谱利用率、高可靠性等优点。在电力配电自动化系统中 ,它是一种理想的数据采集和传输的通信网络或备用通道。介绍ReFLEX、PLANET、Mobitex和Nexnet四种无线专网 ,并从技术特性、用途等方面进行了分析比较 ,选定了较佳的Mobitex组网方案。针对目前配电自动化通信系统中存在的问题 。
Special wireless data network indicates mobile narrow-band data communication network.Compared with traditional mobile telecommunication,special wireless data network has good qualities in constructing cost,frequency-spectrum utilization,reliability and so on.It's better data gathering and transmission network or standby channels in power distribution network automation.Four kinds of products:ReFLEX, PLANET,Mobitex and Nexnet are introduced.Based on the discussion and comparison,Mobitex is chosen as the preferable product that is fit to Chinese conditions.The application of Mobitex technique in automation of power distribution network is discussed.
