基于Windows的全软件数控系统体系结构研究

Architecture Study about All Software CNC System Based on Windows

全软件数控系统是实现开放式数控系统的有效途径。在分析Windows操作系统体系结构的基础上,提出采用分层结构的多线程结构式数控系统软件模型,数控系统的强实时控制由操作系统底层的驱动程序部分完成,弱实时部分以及控制系统的管理程序在操作系统的应用程序层实现,很好地解决了Windows操作系统在数控系统实时控制方面的应用问题,为Windows操作系统下实现开放式数控系统的软件结构模型提出了有效途径。实验证明该方法是行之有效的。

All software CNC system is an effective way to realize open CNC system. Based on the analysis,the multithreading model about CNC system software was given. In the software model,the real-time control of the CNC system was finished by WDM driver of the Windows operating system,and the weak real-time with the management part about control system was implemented by the application program layer of the Windows operating system. The real-time control of CNC system in the Windows operating system was solved well. A effective method was given to build the software model. Experiment shows that the method is effective.
