现代制造业对数控系统的开放性、可扩展性和网络化提出了更高的要求。介绍了实时以太网技术，并讨论了其在数控系统中的应用。与传统的现场总线相比，本文讨论了一种实时以太网，它通过对以太网数据链路层的改进，实现了更快的传输时间和更高的同步精度。提出了一种通过对分布时钟进行同步来减小同步帧传输累积抖动的方法。讨论了这种实时以太网的一些特殊考虑，例如，与Windows NT合并，并使反馈更快地返回。基于这种实时以太网和Windows NT的数控系统已经开发和提出。该系统包括面向服务的Windows Communication Foundation作为Internet的上层接口，以及用于连接机床硬件组件的实时以太网。Windows NT的非实时方面也被考虑在内;例如，引入了一个重写中断描述符表的驱动程序，并缓冲了要发送的数据包。系统的设计与实现，如NC内核中的主要类和服务，主要模块（如，数据链路层）的协议。最后给出了实验结果，验证了该同步方法在Windows NT下的性能和实时性。
Modern manufacturing industry requires computer numerical control (CNC) systems to be more open, extendable, and networked. Real-time Ethernet is introduced and its use in CNC is discussed in this paper. Compared to traditional fieldbus, a real-time Ethernet which modifies the Ethernet data link layer to achieve fast delivery time and high synchronization accuracy is discussed. The method of synchronizing distributing clocks to reduce cumulative jitter of transmission for a synchronization frame is proposed. Some special considerations of this real-time Ethernet are discussed, e.g., incorporation with Windows NT and making feedback returned faster. A CNC system based on such a real-time Ethernet and Windows NT has been developed and presented. The system involves the service-oriented Windows Communication Foundation as an up-layer interface to the Internet, and a real-time Ethernet for connecting to hardware components of a machine tool. The non-real-time aspect of Windows NT is accounted for; for example, a driver rewriting the interrupt descriptor table is introduced and packets to be sent are buffered. Design and implementation of this system, such as main classes and services in the NC kernel, main modules (e.g., data link layer) in salve nodes, are also discussed. At last, experimental results are presented to illustrate the Windows NT’s performance and the real-time accuracy of the synchronization method.
