基于单片机数字转速表设计

The design of digital tachometer based on single-chip

基于单片机数字转速表设计是以单片机(AT89S52)为控制芯片,利用S52单片机三个定时器的特点,运用转速测量M/T法,通过对光电编码盘输出的脉冲信号测量获得电动机转速。测量精度高,范围宽。

This design is based on single-chip microcomputer （AT89S52） for the control of the chip,using S52 timer features three single-chip, the use of speed measuring M/T method, optical encoder disc of the pulse signal output motor speed measurement device.Measurement of high precision, wide range of strong anti-interference.
