Abstract:
This paper introduces a simple speed-measuring apparatus equipped with single-chip microcom- puter,MCS-51.It can be used in wide fields with excellent precision.A progressive method of time sampling is adopted for programming,i.e.transfer the time per revolution to speed (with precision of 0.001s).So the characters of MCS-51,good controlling and running ability,are fully utilized.In the time-measuring pro- gramm,two impulse signals,sampled by photo-electric transformation are wisely adopted to start and stop the counter respectively.
