Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. It is understandable that the described embodiments are only a part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the protection scope of the present invention.

[0044] Such as image 3 Shown is a schematic diagram of a method for identifying the severity of snoring in a current time window in an embodiment of the present invention. First, two types of severity of snoring are defined: severe and mild. The Gaussian mixture model (GMM, "Speech Signal Processing" 2nd Edition, edited by Zhao Li, Machinery Industry Press, pages 228-230) is used to model the snoring signal feature vector sequence and ...

Abstract

The invention relates to a method and system of snoring monitoring and prevention and treatment based on a smart phone platform. The system comprises a snoring sound analysis module, a real-time intervention module and an information feedback module. The method of monitoring and prevention and treatment comprises the following steps that: (1) building a severe snoring sound signal bank and a mild snoring sound signal bank, preprocessing snoring sound signals to extract feature vectors, and training server and mild GMM modules, (2) recording snoring signals of a user in a phone client in real time to process the snoring signals, and carrying out real-time four-dimensional feature vector series extraction on processed snoring signals in a special time window, (3) matching real-time four-dimensional feature vector series with the mild and server snoring sound GMM modules, and regarding one type with the maximum likelihood as an identification result, (4) calculating the maximum snoring sound interval time in a current time window if snoring degree is judged to be server, (5) utilizing outside simulation to prevent the user from snoring if the maximum snoring sound interval time exceeds 10 seconds. Outside intervention can be conducted immediately, and the user can be prevented from snoring effectively.

Description

Technical field [0001] The invention relates to a snoring monitoring and prevention method and system. The system specifically relates to a snoring signal analysis method, determination of the severity of snoring and corresponding external intervention measures, which can be used for online monitoring of the sleep status of snorers and belongs to the technical field of signal processing. Background technique [0002] Snoring is caused by the vibration of the soft tissues around the airway when the airflow passes through the narrow part of the upper airway during breathing. Snoring is a common sleep phenomenon. In fact, snoring is the enemy of health. When a patient snoring, it will cause severe hypoxia in the brain and blood, hindering the normal progress of metabolism, leading to the death of some cells, and accumulating it over time will damage various organs of the body and cause more than 100 diseases. It even causes severe sleep apnea syndrome, leading to death from suffoca...
