摘要 为加快我国全开放CNC的研究步伐,缩短与国外的差距,本文针对国内在数控系统方面的研究状况,提出了全开放PCNC的设计方案,即除了要实现数控软件的开放,还应实现数控系统硬件功能模块化。
首先,总结了开放式CNC最新研究进展和设备驱动程序的主要技术思想,详细分析WDM驱动程序的新特点、工作原理、基本结构以及其开发工具,并结合实际经验给出开发WDM驱动程序的基本流程。
然后,阐述了全开放CNC基本原理和构成等,并把重点放在PCNC硬件功能模块的底层通讯的开发上,采用微软推出最新一代的WDM技术,在Windows2000平台上为PCNC中的数字I/O模块(HY一6140数字输入卡)开发了一个WDM设备驱动程序,通过实际测试能够实时准确地读取外部的数字信号。
最后,给出PCNC中各硬件功能模块协调工作与监控的设计方法,并讨论了全开放PCNC实现中的数控加工语言和机床与控制器的硬件连接两个问题。
