摘　　要：本文介绍了一种基于单片机技术制作的心率计,该心率计采用红外光学检测法,通过检测人体组织的半透明度随心脏的搏动而变化,由于此信号的频率与人体的脉搏次数成正比,将该信号转换成脉沖信号并进行整形和计数,用数码管实时地显示出每分钟脉搏跳动的次数.A cardiotach ometer based on the control of MCU is introduced.This cardiotach ometer is made by infrared optical measurement.When the frequency of heartbeats changes and the transparency of some tissue changes, we can translate the changes into the electrical signals.The frequency of the signal is a direct proportion with the frequency of heartbeats.After processing by MCU, we can know the times of the heartbeats in a minute with the LED digitron.

关 键 词：单片机 心率计 脉搏 显示
