Based on the cun-guan-chi pulse acquisition instrument,a new method for multi-channel pulse acquisition was explored in this paper,and the effect of pulse condition information varying with single sensor pressure of other departments was studied.Moreover a new method named NILP(new intersection points of lines and pulse waveform)was proposed.LIP(lowest point in one period)algorithm based on cubic spline interpolation and wavelet transform was used to preprocess cun-guan-chi signals.The multiple features of ...
