摘　　要：构建了一个基于2层网络的可监控数控系统。控制器基于PC架构,使用Windows 2000操作系统,在进行实时扩展之后,弥补了操作系统实时性不足的弱点。将Profibus-DP总线和SERCOS总线应用于控制器设计中,解决了数控系统因信息交互密集而产生的实时性、可靠性差的问题。将故障监测与诊断技术用于数控系统设计中,构建了层次化的可监控体系,开发了原型机,在数控系统网络化研究方面进行了探索。A monitor CNC system based on tow-layer-network was designed. Its controller was based on PC structure, and Windows 2000 operating-system was used, and whose real-time weakness has been solved by RTX. The problems of bad real-time and reliability which were caused by condensed information exchange have been solved by using Profibus-DP and SERCOS bus. Fault monitoring and diagnosis technologies were contact with CNC system designation and a layer-monitoring architecture has been created in prototype machine. Heuristic working in CNC system＇s network has been done.

关 键 词：数控系统 监控 SERCOS总线 层次化
