摘要:介绍一种应用AVR单片机的内燃机车柴油机转速测量装置,克服了以往由于转速传感器输出脉冲少而必需增加倍频电路的缺点,节约了成本。由于摒弃了定时采样而采用了测量脉冲宽度的方法,测量精度也得到了大大的提高。通过在东风4B/4D型内燃机车上的应用得到了良好的测量结果。

Abstract: The paper introduces the speed
measurement device equ ip ped with AVR microcontroller for locomotive
engine.The device reduces cost for t he necessary frequency multiplication for
speed sensor is not needed in the devi ce because speed sensor outputs low
pulse,and gets a much high measurement preci sion by the method of measuring
width of pulse instead of time sampling.The devi ce has been used in the
Dongfeng 4B/4D locomotive engine with a good result.
