基于信号质量检测的腕式生理监测系统
摘要
设计了一种基于信号检测的腕式生理监测系统
嵌入一种基于循环自相关的信号检测算法
用于检测腕式生理监测系统的佩戴状态。依据信号质量参数
将信号标记为佩戴和不佩戴2种状态。佩戴状态时
计算并显示时间和脉率;不佩戴时
显示时间
脉率显示为0。实验表明:监测系统脉率显示更加精细、精准化。同时
将腕表与Phillip DB18进行了对比实验
脉率的准确度为±2 bpm。
Abstract
A signal detection algorithm based on cyclic autocorrelation is designed for wrist-type monitoring system.According to quality of signal
signal is marked as wearing and un-wearing.When the state is wearing
time and pulse rate are computed and displayed
otherwise
the pulse rate is displayed zero and the time is displayed.Through comparison experiments with Phillip DB18
