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.

简简单单教您熟练使用proteus仿真
注意，PROTEUS软件也可能能在Windows 98，NT, Millennuium等合法windows 系统中使用，只不过LABCENTER和MICROSOFT都已经不再对此提供技术支持服务。
对于PROTEUS VSM 处理器仿真，电脑CPU越快，仿真效果更好。一台1G处理器，256MB内存，150MB硬盘的电脑是进行仿真的最低配置。

动态显示的特点是将所有位数码管的段选线并联在一起，由位选线控制是哪一位数码管有效。这样一来，就没有必要每一位数码管配一个锁存器，从而大大地简化了硬件电路。选亮数码管采用动态扫描显示。所谓动态扫描显示即轮流向各位数码管送出字形码和相应的位选，利用发光管的余辉和人眼视觉暂留作用，使人的感觉好像各位数码管同时都在显示。动态显示的亮度比静态显示要差一些，所以在选择限流电阻时应略小于静态显示电路中的。
Dynamic display features all the bits of digital control of segment-select line connected in parallel, from the bit selector control which a digital control effectively. Thus, it is not necessary with each of the digital control of a latch, thereby greatly simplifying the hardware circuit. Select the digital control using dynamic light scanning display. The so-called dynamic scan revealed that in turn send to you the digital control code and the corresponding bit font selection, use of LED in the afterglow and the human visual temporary stay in effect, make people feel like you are in the display while the digital control. Dynamic display of the brightness of some worse than a static display, so the choice should be slightly less than the current limiting resistor, a static display in the circuit.
