Detection mechanism and method for dynamically recognizing breathing state

Abstract

The invention relates to a detection mechanism for dynamically recognizing a breathing state. The detection mechanism comprises a line light source, a height adjusting mechanism, a projection plate, a dynamic recognition unit and a data processing unit, the data processing unit is used for receiving and processing the projection picture information and controlling the height adjusting mechanism to adjust the line light source to a set height position; the data processing unit is further used for delimiting a detection calibration channel right opposite to the nostrils in the area and comparing the moving state of dust in the detection channel with a pre-stored standard moving state to judge the current breathing state; the dust movement condition around the nose is shot and captured in a lighting mode, the breathing state is judged according to the dust movement condition, wearing discomfort is avoided, meanwhile, the detection mode is quite direct, the detection result reliability is good, and the detection cost is low.

Description

Technical field [0001] The present invention relates to a breathing state detection technology, and more particularly, relates to a dynamic identification respiratory state detection means and methods. Background technique [0002] Respiratory state detection currently mostly used in two forms, one is through the respiratory body-worn sensor to directly detect the kind of wear detection methods can be uncomfortable experience for the person tested, the other is to rely on the signs data by indirect estimation algorithm breathing state, this manner is susceptible to interference accuracy, poor reliability, a need for a more reliable and non-wearable respiratory dynamic state detection means and identification methods. Inventive content [0003] The present invention is to solve the technical problem is that, for the above-described drawbacks of the prior art, provides a dynamic identification respiratory state detection means and methods. [0004] The technical solution used by t...

AI Technical Summary

Problems solved by technology

[0002] There are currently two forms of respiratory status detection. One is to directly detect breathing through human body wearable sensors. This wearing detection method will bring discomfort to the person being detected. Indirectly infer the breathing state through the algorithm, the accuracy of this method is easily disturbed, and the reliability is poor, so a more reliable and non-wearable dynamic recognition breathing state detection mechanism and method are needed
