基于局域网的分布式计算机控制系统通信子网的研制

The Designing of Communication Subsystem in DCCS Based on Local-Networks

本文介绍了基于一般局域网的分布式计算机控制系统（ＤＣＣＳ）的通信子网，详细讨论了通信协议的设计与实现。本系统的主要功能是提供了不同站进程间的通信和动态重组协议，实现了通信子网一级的容错，降级运行的功能。通过实际运行证明该系统可靠，实时性好．

This paper describes the.communication system in DCCS based on local-area networks, discusses the designing and realizing of communication protocols in detail. The main functions of this system are the communication between the processes of no same stations and dynamic reconfiguration protocols, realizing the tolerance fault on communication system. After running,this system is proofed that there are high reliability and good real-time property.
