基于体震信号的心率测量方法

心脏向外泵血引起与心跳同步的身体的震动,产生体震信号,其规律与心率相关,可在脊椎轴上通过敏感的力传感器检测出来.体震信号微弱且易受干扰,针对此特点设计了传感器电路和信号处理电路,说明了检测方法.所获得的原始体震信号先经预处理去除噪声,再应用模极大值算法得到每个心动周期中的峰值点,最后求得心率.采集体震信号时,同步采集一路单通道心电信号作为基准,评价测量的准确性.实验结果表明,基于体震信号的心率测量方法获得了良好的效果.

Heart Rate Measurement Based on Fluttering Signal from Human Body

The fluttering signal due to synchronous heartbeat from human body is used to measure heart rate where the body fluttering signal is caused by the heart which pumps blood round the body.The rhythm of the signal associates inevitably with heart rate and can be detected at the vertebral axis of the body by sensitive force sensor.The signal is so weak and easy to be jammed that the sensor circuit and signal processing circuit should be designed specially,from which the method to detect the signal is described....
