摘要
分布式数控系统的基本问题之一是网络的互连与通信问题．文中探讨了ＤＮＣ系统中现场级网络形式的选择，硬件、软件结构及其特点，并在软件设计中着重分析了信息传输中的总线竞争及其解决方法．
One of the important techniques in distributed numerical control (DNC) system is the interconnection and communication of the computers. This paper discusses a choice of the fieldbus architecture of DNC system, presents the hardware and software architecture and characteristics of the system. and much more attention is paid to the emergence and settlement of the bus collision. The collision of information transfer is settled in the software design of the system with the method of CSMA-CD/OB.
