摘要
由于Windows系统提供了友好的人机界面,同时基于它的软件开发与硬件有很大的无关性,且具有很好的兼容性,因而大大提高产品的生命周期,同时也为二次开发和更新换代提供了良好的系统支持。但Windows系统也有它致命的弱点,Windows系统本身是抢占式的多任务系统,对于运行的程序可以说是没有实行性可言的,因此本文将介绍通过编写VxD驱动程序截获系统实时中断实现基于Windows系统的实时控制。
<Abstrcat>Windows system offers a friendly interface, good hardware compatibility and hardware independence. All of those advantages make the Windows system a powerful and ideal platform for industry control. But Windows system has its deadly weaknesses.Windows system is a multitask system. And this makes the system haven't any real-time control ability. This article introduces a new method to solve the problem.The VxD driver is used to capture the RTC interrupt to realize the real-time control under Windows system.
