Wave filter merging method in self organization pulse sensor

Abstract

The invention discloses a wave filter merging method applied to a self organization pulse sensor. The method obtains multi-path pulse wave curves through placing a plurality of piezoelectric sensor point lattices at radial artery parts on the inner side of the wrist, wherein each single-point sensor can separately measure the pulse wave. The curves carry out digital wave filtering and factor analysis in an information merging center according to the following steps that: firstly, the digital wave filtering adopts a small wave processing method, and noise signals such as base line drifting, electromyographical interference, power frequency interference and the like mixed in the pulse waves can be effectively eliminated; and then, the multi-path pulse signals after the wave filtering carry out dimensionality reduction processing through the factor analysis, signal channels with server distortion in the multi-path pulse signals are eliminated, at the same time, two paths of pulse signals are optimized and selected, and finally, the two paths of pulse signals are merged into one path of pulse signals to be output. When the method of the invention is adopted, the real-time output weighing regulation of the sensor point lattices can be realized, so a path of pulse signals nearest to the actual pulse signals can be obtained, and then, the monitoring and the analysis of the real-time pulse signals can be finally realized through the connection of a wireless communication module and a subsequent processing module.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a filter fusion method in a pulse wave intelligent detection device. Background technique [0002] The existing pulse wave detection device requires the subject to be in a calm state when measuring the patient's pulse, and obtains the pulse wave for medical auxiliary diagnosis. However, in the case of dynamic measurement of pulse waves, the existing pulse wave detection devices often cannot meet the requirements in accuracy and have little medical reference value. In the case that the subject needs to be monitored around the clock, the static pulse wave detection device cannot achieve good results. [0003] The existing multi-channel pulse detection device does not consider the appropriate fusion processing method according to the pulse cutting theory in traditional Chinese medicine in the follow-up processing of the pulse wave. How to eliminate the interference cause...
