摘要:
 传统现场总线和以太网技术在分布式数控系统中应用时，存在带宽低和实时性不高的问题，不能满足现代数控高速高精加工要求。反射内存网络是一种实时、确定性的网络，可以较好地解决实时系统中数据传输的实时性问题。文中在分析反射内存网工作原理的基础上，提出了一种基于反射内存网的分布式数控系统实时通信网络方案。根据分布式数控系统的基本框架和反射内存网络的构建方法，对反射内存网在分布式数控系统中应用的通信机制做了深入研究，给出了系统的基本框架结构、节点模型和拓扑结构，旨在探索解决复杂数控系统在功能扩展和系统开放性实现上的网络关键技术问题。
Abstract:
 At present,traditional fieldbus and Ethernet technologies have low bandwidth poor real-time in the application of Distributed Numerical Control ( DNC) system,they can’ t meet the increasing demand of high speed and high precision of modern CNC. Reflective memory network is a real-time,deterministic network,which can solve the problem of real-time data transmission in real-time systems much more better. Based on the analysis of the principle of reflective memory network,a reflective memory network-based real-time communication network solutions for distributed numerical control system is presented. According to the basic framework for distributed numerical control systems and reflective memory network construction method,make a thorough study of the reflective memory network communication mechanism in application of distributed numerical control system. The basic frame structure of the system,the node model and the topological structure were given,aiming at exploring solutions on the key technical issues of complex CNC system extensions and achieving openness of systems.
