摘要
实现DNC系统的核心问题是解决数控机床与计算机之间的信息交换和互联。文章通过对当前国内DNC系统主要通信结构的分析,重点论述了使用通信控制器构建基于以太网数控机床通信系统的网络技术方案、拓扑结构及通信系统功能的软件实现;给出了采用单片机和RTL8019AS以太网控制芯片实现通信控制器的方法。
The central problem to realize DNC system is how to resolve information exchange and inter-connection between NC machine tool and computer. By analyzing the main communication structure of DNC system at present, web technology, topology structure and software realizing of communication function are demonstrated in the article to construct communication system of Serial NC System. The method is also displayed to design Communication Controller made up by SCM and RTL8019AS.
