摘要
针对采用T法测速时存在的两个转速脉冲之间时间间隔测量不便的问题,采用AT89C52单片机的定时器T2进行测量。阐述了定时器T2工作原理,介绍了利用定时器T2实现T法测速的具体实现方式,采用C语言编程,可应用于低速重载设备转速测量系统中。
Since it＇s inconvenient to measure the time interval between two rotational speed pulse signal wheu using T method to measure speed, AT89C52 MCU timer T2 is adopted to speed measurement. The Timer T2 working principle is expounded, the concrete realization way is introduced, C language is used to program. The method can be applied in speed measurement system of low speed and high load equipment.
