基于非实时操作系统和频压转换的实时高精度转速测量方法研究

Research on Real-time and Accuracy Method of Rotational Speed Measurement Based on Non Real-time Operating System and FVC

一般的微机测量方法若要测得到高精度的转速数值,必须通过实时计数(或计时)的方法对转速传感器的脉冲进行分析。介绍了一种在非实时操作系统下通过VC++和多媒体定时器对频压转换后的电压波形进行分析,同样能得到高精度的转速数值方法。

We used to use PC to get rotational speed with using counter to analysis period of the pulse.This paper introduces a new real-time and accuracy method of the rotational speed measurement under a non real-time operating system such as Windows.This method uses VC＋＋ and multimedia timer as tools to analysis the signal waveform converted by FVC.
