Title:
BIOLOGICAL INFORMATION DETECTION METHOD AND BIOLOGICAL INFORMATION DETECTION SYSTEM
Document Type and Number:
Japanese Patent JP2022007811
Kind Code:
A
Abstract:
To provide low cost biological information detection method and system capable of drawing accurate biological information from mixed wave forms even when sources of human body movements and vital signs are superposed with any movement and vibration in a life environment.SOLUTION: A biological information detection method and a system thereof include: mapping processing for storing a displacement and a detection level collected by a sensor in a time-series manner; filtering processing for detecting a frequency component in a specific harmonic band in the neighborhood of the frequency n-times (n being a natural number of 2 or more) of a target pulse from the displacement collected by the sensor; specific component extraction processing for detecting a specific frequency component with a predetermined level from the frequency component in the specific harmonic band and drawing the frequency; and target information specification processing for multiplying the frequency of the specific frequency component by 1/n and drawing a detection frequency of the target pulse.SELECTED DRAWING: Figure 1
