摘　　要：根据在Linux平台上开发强实时应用所采用的双内核操作系统的结构特点,提出了一个基于Linux平台的数控系统设计方案,重新划分了传统用户模式下运行的数控软件体系结构,建立了一个实时控制层、控制接口层和数控应用层的三层模型。根据该模型实现了在Linux平台上的电火花数控系统,并以此为例研究了内核模式中的实时控制层实现,讨论了按控制接口层规范编写数控应用层自定义插件的方法。Based on the double-kernel architecture of some real-time Linux versions, a new design of Numerical Control System on Linux is proposed. The traditional NC software that is running only in the user mode is reorganized into a three-layer model, which includes the real-time control layer, the interface layer and the auxiliary application layer. An example to show how this model works an Electron Discharge Machining (EDM) NC system is analyzed, and the real-time control layer implemented in the kernel mode is studied. The method to develop customized plug-in units in the auxiliary application layer is discussed.
