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.
