Windows控制系统的精确计时机制研究及应用

Research and application of accurate timing mechanism in control system based on windows

如何做到准确计时是控制软件中非常重要的任务,而在Windows系统却没有提供高精度的定时/计时函数。分析了Windows系统的计时原理,提出了一种新的计时方法,可以满足控制软件对定时/计时的高精度要求。

It is very important to accurate time in the control software system but the function of high accurate timing is not provide by windows. The mechanism of timing is analyzed based on windows and a new method is put forward which can meet the needs of high accurate timing.
