摘要
分布式控制系统（DCCS）是一种以通信网络为基本连接的多处理机控制系统。高可靠性和高可用性是DCCS系统的主要特点之一。在一些重要的过程控制应用中，为保证系统的高可靠性指标需要对分布式控制系统的可靠性进行分析与设计。本文在提出DCCS系统中的两个主要环节通信网络和智能化模块的可靠性数学模型基础上，讨论了DCCS系统的可靠性分析方法与一般设计步骤。
Distributed computer control system (DCCS) is a type of multiple computer control system in which the connection between computers is made up by communication network. High reliability and high availability is major character of DCCS. In many applications,the reliability analysis and design are very important that could insure high reliability of DCCS. This paper,based on the reliability mathematical model of network and the model of computerized module,presents a means of reliability analysis and design.
