实时高可靠工控局域网的实现

THE REALIZATION OF A HIGH RELIABLE LOCAL AREA NETWORK

本文分析了工控局域网的现状，并根据变电站综合自动化系统对局域网的要求以及多年从事局域网研究的经验，设计了一种新型的高可靠工控局域网ＨＲＬＡＮ。它在可靠性、实时性、灵活性、方便性和适用性等方面有特色。本文介绍其设计思想及其软硬件实现，并讨论了有关问题。

In the area of industrial control, e. g., Integrated Substation Automation Computer System(ISACS),a LAN is required to be of high reliability, suitability and be real-time in operation. Through years of research in LAN and analysis in ISACS, a new Highly Reliable Local Area Network (HRLAN) is described in this paper. The idea of HRLAN's design and the realization of its software and hardware is also presented.
