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.-The heart to pump blood out of the body caused by vibrations synchronized with the heartbeat, tremor signal generating body, its own rules and heart-related, can be detected by sensitive spinal axis force sensor body fluttering signal is weak and susceptible to interference, for this feature designed the sensor circuit and signal processing circuit, the detection method described. first original body fluttering signal obtained pre-treated to remove noise and then apply the modulus maxima algorithm for each cardiac cycle peak point, and finally determined the heart rate. when collecting body fluttering signal all the way to a single-channel synchronous acquisition accuracy of ECG as a reference to　uate the measurement results show that, to obtain good results heart rate measurement method body shock signal.
