摘要
针对PVDF型脉搏传感器用于脉搏信号的采集,提出了一种脉搏信号处理方法。信号处理硬件电路包括一级放大器、基线校正电路、带通滤波器、50 Hz工频陷波电路和二级放大电路等组成,软件去除噪声干扰信号采用数字滤波技术中的中值滤波技术。此方法较好地还原了真实的脉搏信号,有利于脉搏信号的测量和监测。
a new method for pulse signal process is proposed according to PVDF type pulse sensor. Pulse signal process hardware circuit includes first signal amplification circuit, Baseline Calibration circuit, Band-pass filter circuit, 50Hz Notch Filter circuit, second signal amplification circuit etc. Median filtering algorithm was adopted to weaken the effect of noise in software. This method is better to restore the true pulse signal, it is conducive to the pulse signal measurement and monitoring.
