Respiration monitoring method and device and terminal equipment

Abstract

The invention provides a respiration monitoring method. The method comprises the steps that a three-axis acceleration signal of a user respiration signal is obtained; respectively carrying out sliding filtering and low-pass filtering on the three-axis acceleration signals of the respiratory signal in the sliding window to obtain three axial respiratory signals; respectively calculating a target peak amplitude standard deviation, a target peak amplitude mean value, a respiration interval and a respiration interval standard deviation of each axial direction according to the respiration signals of the three axial directions; screening one axial direction from the three axial directions as a target axial direction according to the target peak amplitude standard deviation, the target peak amplitude mean value and the breathing interval standard deviation of each axial direction; performing abnormal completion processing on each breathing interval in the target axial direction to obtain a target breathing interval sequence in the target axial direction; and calculating breathing parameters according to the target breathing interval sequence in the target axial direction. According to the method, the respiration signals can be collected and tracked based on the three-axis acceleration signals of the respiration signals of the user, operation is convenient and fast, calculation is simple, and the application range is wide.

Description

technical field [0001] The present application relates to the technical field of wearable devices, in particular to a breathing monitoring method, device and terminal device. Background technique [0002] In recent years, with the improvement of living standards, more and more people have begun to pay attention to their health, and respiratory monitoring technology suitable for home use has emerged as the times require. Among them, respiratory monitoring results, as one of the important components of sleep monitoring, have received more and more attention because they can play a key role in the prevention, diagnosis and treatment of sleep-disordered breathing. [0003] In the prior art, daily respiratory monitoring is mainly realized through methods such as mouth and nose airflow pressure method, temperature sensing method, chest cavity inductive impedance method, and chest and abdomen movement method. However, the aforementioned methods usually have high cost, large volume,...
