基于RapidIO的智能电网测控装置嵌入式总线的研究

Research on the Embedded System Interconnect of LED based on RapidIO

随着智能电网的发展,数字化变电站被赋予了更多功能。电力测控装置作为数字化变电站的关键设备,也随之变得越来越复杂,而现有的嵌入式系统互联方式严重制约着系统的规模和数据流量。本文分析了RapidIO(高性能嵌入式互连技术)在嵌入式系统互联中的优势,并结合电力测控装置的结构提出了基于环形拓扑结构的RapidIO互联方案。测试数据表明,在小规模的系统互联应用中,基于RapidIO的智能电力测控装置具有通信速率高,扩展性强,安全性好,成本低等优点。

With the development of smart grid, more multifunctional has been given in digitized substation. As the key equipment of digitized substation, power monitoring and control devices becomes more and more complicated, but now the intereonneetion way of embedded systems in the dcvic has been restricted the systematic scale and data rate of flow gravely, this paper analyzed the advantage of RapidlO in embedded systems interconnect, and proposed RapidlO intereonneetion scheme based on ring topology, which is combined with the structure of the power monitoring and control device. The testing data indleates that this scheme is fit for intelligent power monitoring and control devices internal system intcreonncclion, which has high rate, strong expansibility, good security, low cost.
