Windows2000环境下实时控制系统的软件实现

The Implementation of the Real-time Software of Control System under Windows2000

文章介绍了在windows2000环境下通过编写WDM(WindowsDriverModel)设备驱动程序实现实时数据采集和控制的一种方法。采用研华数据采集卡PCL818L产生中断信号,通过编写WDM驱动程序实现了在win-dows2000环境下转台的位置控制,并在实验中调试通过。实验结果表明:在采样频率为1KHz的情况下,控制系统很好实现了输出对输入的跟踪,证明了采用方法的正确性。该方法解决了windows2000环境下的实时性问题,为在windows环境下实时控制系统的实现提供了有益的尝试。

A way to realize the real-time data collecting and control through the WDM device driver under windows2000 is presented in this paper. The Yanhua data collecting card was used to make interrupts. The location control of platform transfer was implemented through the WDM device driver in experiment. The experiment result shows that when the sampling frequency is 1 KHz, the output follows up the scents of the input very well through the control system. It demonstrates that the way is right. The real-time problem under windows2000 was solved by this way, and a profitable attempt is provided for the realization of the real-time control system under windows2000.
