摘要
本文介绍了在基于ＰＣ和Ｗｉｎｄｏｗｓ ９Ｘ平台下实现实时控制的关键技术一一实时钟中断的获取方法，对虚拟设备驱动程序（ＶｘＤ）和ＶｔｏｏｌｓＤ工具箱进行了简要介绍。通过对源代码的分析说明了实时硬件中断ＶｘＤ的实现过程。
This paper describes the method of acquiring real time clock interrupts, which is the key technology of real time system design based on PC and Windows 9x. The VxD Virtual Device Driver and VtoolsD Toolbox are also introduced briefly. Implementation of the real time interrupt VxD is illustrated by the source code analysis.
