容错集散控制系统通信网的研究

The Research on Communication Network in a Fault-toler-ant Distributed Control System

通信网是容错集散控制系统的命脉。本文结合容错型变电站自动化监控系统的实例，详细论述了基于串口通信和基于局域网技术的容错集散控制系统通信网。

Communication network is very important in a fault-tolerant distributed control system. With the example of a fault -tolerant substation automatic monitored control system,this paper describes two models for it. One is based on serial port,and the other on local area network.
