摘要
为了实现人体心血管多参数检测,设计了一种基于光电容积脉搏波描记法(photoplethysmography,PPG)的心血管多参数检测系统。该系统采用S5PV210处理器为控制核心,设计了指端脉搏波采集及滤波电路,提取指端脉搏波信号特征,测量人体心率、血氧饱和度、血压值。结果表明:与标准仪器对比,心率测量最大误差为5次/min;血氧饱和度测量最大误差为2%;血压测量满足ANSI/AA-MI国际电子血压仪标准。
In order to detect the human cardiovascular multi-parameter,a cardiovascular multi-parameter detection system based on photoplethysmography(PPG)was designed.In the system,S5PV210 processor was used as the control core,and a finger-pulse wave acquisition and filter circuit were designed.Extracted the signal characteristics of finger-pulse wave to measure human heart rate,blood oxygen saturation and blood pressure.The results show that comparing with standard instruments,the maximum error of heart rate measurement is 5 beats/min,the maximum error of blood oxygen saturation measurement is 2%.Blood pressure measurement meets ANSI/AA-MI international electronic sphygmomanometer standard.
