Abstract: This paper presents a method of pulse waveform automatic judgment and detection automatic control.Pulse waveform detecting automatically started by the judgment of sampling value change caused by transducer clamping on finger.The effective pulse waveform was obtained after analog and digital filtering of pulse wave signal and removal of baseline drift.Single pulse waveform was obtained by the extraction of starting points utilizing the differential threshold method.Single pulse waveform was automatically identified based on classification of single pulse wave pulse waveforms.Pulse waveform detecting automatically stopped by the judgment of the absolute errors of continuous three-screen average pulse waveform characteristic values less than 0.005. Results of actual measurement experiments show that pulse waveform can be effectively identified and detection of pulse waveform can be automatically controlled.This method has a wide range of applications in pulse wave detection.
