摘要
讨论了基于单片机的电机转速及功率因数的测量问题,给出了实用的电机转速和功率因数测量电路,并就采用一片8031同时测量电机转速及功率因数时存在的多中断源问题进行了分析,提出了在8031周围扩展两片定时计数芯片8253的解决方案.
The application to measure rotate speed and power factor of an electromotor based on single-chip microcomputer is probed into. An applied circuit, parameter measure of rotate speed and power factor of an electromotor is given,and the multiple interrupt problems in measuring rotate speed and power factor of an electromotor by a single-chip microcomputer (8031) are analysed.Based on this,a solution for multiple interrupt problems by extended tow 8253 timing chip is put forward.
