Respiratory pattern judgement method based on respiratory pattern monitoring radar

Abstract

The invention discloses a method based on respiratory pattern monitoring radar. The respiratory pattern judgement method includes the following steps: step 1, a monitored heartbeat and a respiratory mixed signal are demodulated through a respiratory pattern monitoring radar collection signal, a respiratory signal is obtained, a low-pass filtering is conducted for the respiratory signal obtained by a removed noise jamming; step 2, the respiratory signal of the removed noise jamming is captured for 30 second, and the feature is extracted, the characteristic parameter of different respiratory pattern respiratory signal can be differentiated; step 3, a mapping relation between the different respiratory pattern and the characteristic parameter is confirmed; step 4, according to the mapping relation in step 3, what kind of the respiratory pattern in the respiratory signal obtained from the respiratory pattern monitoring radar is judged. According to the respiratory pattern judgement method, the respiratory pattern judgement method is valid and workable, performance is reliable, and the respiratory pattern can be precisely judged.

Description

technical field [0001] The invention belongs to the field of radar, in particular to a breathing pattern judgment method based on breathing pattern monitoring radar. Background technique [0002] Respiration is one of the important signals reflecting the state of the human body. [0003] The traditional method of respiratory monitoring is contact monitoring. The electrodes used in contact monitoring will make the monitored person feel restrained and uncomfortable, which will affect the physiological characteristics of the monitored person and interfere with the monitoring results. And monitoring monitoring cannot directly contact some patients, which will limit the scope of application. For example, contact respiratory monitoring cannot monitor patients with large area burns, patients with sensory diseases, patients with skin diseases, and newborn babies. In addition, monitoring monitoring requires professional medical staff to prepare for nearly an hour before each monito...

AI Technical Summary

Problems solved by technology

The electrodes used in contact monitoring will make the monitored person feel restrained and uncomfortable, which will affect the physiological characteristics of the monitored person and interfere with the monitoring results

And monitoring monitoring cannot directly contact some patients, which will limit the scope of application, for example: contact respiratory monitoring cannot monitor patients with large area burns, patients with sensory diseases, patients with skin diseases, and newborn babies

In addition, monitoring monitoring requires professional medical staff to prepare for nearly an hour before each monitoring, and the operation is cumbersome, which will consume a certain amount of manpower and financial resources, and cannot achieve long-term monitoring of breathing

[0004] Therefore, there is an urgent need for a non-contact breathing pattern monitoring method, but there is no relevant description in the prior art
