摘　　要：本设计采用透射式光电效应手指脉搏传感器来拾取脉搏信号,由Atmel公司生产STC12C5A60S2单片机完成数据处理。利用主控芯片为控制器ILI9325的2.4FTF点阵式液晶显示屏来完成数字与波形显示。它能有效、准确、高清晰度地给出脉搏波形,并设定当人在平静状态下所测得的脉搏次数小于50或大于120时,蜂鸣器发出报警。Reference to the pulse detector, the transmission-type and photo-electrical effect finger pulse sensor is adopted in which to col ect signals, while STC12C5A60S2 SCM manufactured by Atmel is to approach data. With the aid of the main chip, digits and waveforms are displayed through ILI9325 control er’s 2.4 FTF dot-matrix LCD. Not only can the detector of this design effectively, precisely show waveforms with high definition, but it also can alarm through the buzzer if the given precondition is that the pulse rate of the sample being in calm state is less than 50 or greater than 120.
