基于Labview的压力控制脉搏采集系统

为了提取更多的脉搏信息，设计出一种可控制压力大小的脉搏采集系统。该系统的设计不仅实现了对脉搏压力自动的选择，它还通过压力信号反馈于控制信号，控制信号决定加压还是减压．这样就保证了压力的稳定以及采集的脉搏信号的稳定。这克服了以往压力脉搏采集系统的压力不稳定的弊端，可以采集到稳定的脉搏信息。该系统还可以模拟脉诊系统中的浮、中、沉3种指力，这样就可以获取不同压力下的脉搏信号．可以方便对不同状态下的脉搏信号进行提取分析。

Pressure control and pulse acquisition system based Labview

In order to extract more pulse information,the paper designs a controlled pressure on the size of the pulse acquisition system.The system is designed not only to achieve the automatic selection of the pulse pressure,it through the pressure signal feedback control signal,control signal determines the pressure or reduced pressure,thus ensuring the stability of the pressure and the stability of the collected pulse signals.Which overcomes the drawbacks of the past,the pressure pulse acquisition system pressure instability,can be collected to the steady pulse of information.The system can also simulate a floating pulse system,Shen three refers to the force,so that you can get the pulse of the signal under different pressures,can be easily extracted under different conditions of pulse signal analysis.
