利用386微机实现宽转速范围高精度转速测量

High Precision and Wide Range Rotational Speed Measurement Based-on 386 Microcomputer

本文介绍了一种基于386微机的转速测量方法,该方法克服了一般数字式转速测量方法高、低速精度不等以及精度不高的缺陷,可实现宽转速范围的等精度测量,测量精度可达2.3×10^(-10)。

This paper presents an 386 microcomputer based method to measure rotational speed, which can maintain a constant precision in a wide speed range and is free from weakness of common digital measurement methods, i. e. the precision changes with speed range. The measuring accuracy can reach 2. 3 X10-10.
