Problems solved by technology

However, the above analysis is a simple time-domain analysis, which cannot describe the specific characteristics of the human body condition.
In addition, at present, Fourier transform and wavelet analysis methods are mainly used to analyze the characteristics of the pulse wave. However, these analysis methods are difficult to solve the impact of various clutter signals of different frequencies superimposed by the influence of internal organs during the pulse wave transmission process. The influence of the pulse wave of the human body

Abstract

The present invention relates to a pulse wave analysis method and device. The method comprises steps: step 1, receiving the original pulse wave to be analyzed; step 2, decomposing the original pulse wave, and extracting several pulse waves from the original pulse wave Intrinsic mode function; step 3, select an intrinsic mode function closest to the original pulse wave, carry out Hilbert transform based on the intrinsic mode function, obtain the marginal spectral density function of the original pulse wave, and use the The maximum frequency of the marginal spectral density function is output as the maximum frequency of the original pulse wave. The method of the present invention is to analyze the pulse wave in the frequency domain, which can eliminate the influence of multiple clutter signals of different frequencies superimposed by the influence of internal organs on the pulse wave of the human body during the transmission process of the pulse wave, and has high accuracy. The maximum output frequency is used as a physiological index to evaluate the cardiovascular health status.

Description

technical field [0001] The invention relates to the technical field of signal analysis, in particular to a pulse wave analysis method and device. Background technique [0002] The theory of traditional Chinese medicine pays attention to the four characters of "look, smell, ask, and feel", among which "cut" is to diagnose the health status of the human body by feeling the pulse. However, Chinese medicine diagnosis is mainly based on experience, and there is no digital feature for analysis; Western medicine also often uses pulse frequency to analyze the heartbeat state of the human body. However, the above analysis is a simple time-domain analysis, which cannot describe the specific characteristics of the human body condition. In addition, at present, Fourier transform and wavelet analysis methods are mainly used to analyze the characteristics of the pulse wave. However, these analysis methods are difficult to solve the impact of various clutter signals of different frequenci...
