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

accuracy of pulse rate is ±2 bpm.
