摘　　要：设计了以STC89C51单片机为控制核心的脉搏检测仪,利用脉搏传感器采集脉搏信号转为电信号并通过二级放大电路、低通滤波电路和ADC对信号处理,实现对人体脉搏信号的检测及脉搏曲线的显示。脉搏信号检测实验结果表明,该脉搏检测仪能够正确地检测人体脉搏信号,并能及时反映脉搏曲线变化,具有灵敏度高、可靠性高和抗干扰能力强等优点。A Pulse Signal Detection Device based on STC89C51 was designed. The pulse signals was collected and converted into electrical signal through pulse sensor. The signal was then processed by secondary amplifying circuit, low pass filter circuit and the ADC. The pulse signal was obtained and shown with pulse curve. The experimental results show that it can detect human pulse signal precisely, and reflect the pulse curve change timely. It has advantages of high sensitivity, high reliability and strong ant i-in-terference ability.
