基于嵌入式Linux的网络RTU

分布式的网络远动终端单元RTU(Remote Terminal Unit)在功能、可靠性、易维护方面显现出其相对于传统RTU的优势。介绍了一种基于嵌入式Linux的分布式网络RTU，它具有强大的网络通信功能和良好的开放性。RTU不仅是一种数据采集和控制的终端装置，它可以集成很多扩展模块成为变电站的信息处理核心平台。特别是在分级电压控制系统中．作为一级电压控制的无功／电压当地控制模块完全可集成到网络RTU中。这种模式一方面有利于与二级电压控制系统协调．另一方面也方便维护并可有效降低投资成本。

A network RTU based on embedded Linux

Distributed network RTU is showing its merits in function,reliability and maintenance comparing to traditional one. A distributed network RTU based on embedded Linux is developed. It has powerful network communication ability and an open architecture. RTU is not only a data-acquisition and control terminal,it can also act as a kernel information management platform in substation. The var / voltage regulating module,integrated in RTU as the first layer in layered voltage control system,can coordinate with the second layer,which facilitates the maintenance and reduces the total investment.
