摘要
本设计采用透射式光电效应手指脉搏传感器来识取脉搏信号,由低功耗单片机80C51完成数据处理,并利用全屏幕点阵式液晶显示器SED1330来完成数字与波形显示。它能实时、准确、高清晰度地给出脉搏波形和脉搏次数,当测得数据超限时报警。通过波形可观测人体心跳的强弱与规律。可作为一简单的心电图仪来使用。
The system identifies the pulse signal from the photoelectric finger pulse sensor .The 89C51 is used to control the data processing, data display and the keyboard input. The data and wave are displayed by Matrix LCD EDM16032B. The intensity and the pulsating of the heartbeat can be observed by the wave in LCD. So it can be used as a simple electrocardiogram.
