摘要
以通用PC为硬件平台、PC操作系统为软件平台开发基于PC的数控系统是当前数控系统的一个重要发展方向。目前,DOS和Windows是PC上的主流操作系统,但由于DOS实现功能的局限性和Windows非实时性的特点,本文提出了完全以实时应用为目标的RT-Linux解决方案。着重介绍了RT-Linux在数控系统中的实时控制实现原理,给出了基于RT-Linux的数控系统软件结构。并指出了该技术今后的发展方向。
PC-based CNC system is one of the important developing directions of CNC system. At present, DOS and Windows are the popular operating sysm.but ,becautese of the limitation of the realizable function using DOS and the characteristic of the asynchronism utilizing Windows, this paper puts forward a RT-Linux solution aiming at realtime application,and detailedly analyses the the basic principle that construct＇RT-Linux OS in CNC,then gives a software structure of a numerical control system based on RT-Linux,finally indicates the developing diretion of such a technology.
