Problems solved by technology
The existing anti-snoring instruments are not scientific enough to process the collected snoring sound and blood oxygen parameters, making it difficult to accurately and quickly judge the degree of snoring, which in turn affects the subsequent anti-snoring treatment

Embodiment Construction
[0037] see figure 1 , a kind of intermediate frequency anti-snoring instrument data processing method based on snoring sound and blood oxygen, it comprises the following steps:
[0038] S1: Obtain snoring sound and blood oxygen signal, and preprocess the acquired snoring sound;
[0039] S2: segmenting the preprocessed sound signal in step S1, taking the sound signal in each set time period as a frame, and extracting effective information therein;
[0040] S3: Using the random forest algorithm, the recursive feature elimination algorithm, and the normalized exponential function algorithm in sequence to analyze the effective information in step S2 and judge the severity of snoring.
[0041] The data processing method of the intermediate frequency anti-snoring instrument based on snoring sound and blood oxygen of the present invention can accurately and quickly judge the degree of snoring, and can classify the degree of snoring, and can automatically identify the category, so as...

The invention discloses an intermediate-frequency anti-snoring instrument data processing method based on snore and blood oxygen. The method includes the following steps that S1, snoring sounds and blood oxygen signals are acquired, and the acquired snoring sound data is preprocessed; S2, the preprocessed sound signals in step S1 are segmented, sound signals in each set time period are taken as one frame, and effective information in the sound signals is extracted; S3, a random forest algorithm, a recursive feature elimination algorithm and a normalized exponential function algorithm are adopted in sequence to analyze the effective information in step S2 and judge the snoring severity degree. By means of the intermediate-frequency anti-snoring instrument data processing method based on thesnore and the blood oxygen, the snoring degree can be accurately and quickly judged, the snoring degree can be classified, and the class can be automatically identified so that intermediate-frequencytherapy can be conveniently adopted for subsequent diagnosis and treatment.
Description
technical field [0001] The invention relates to the technical field of intermediate frequency anti-snoring devices, in particular to a data processing method for intermediate frequency anti-snoring devices based on snoring sound and blood oxygen. Background technique [0002] Snoring is an abnormal breathing sound, which is caused by pathological changes or improper sleeping posture. The frequency range of snoring is (200-800) Hz. Clinical studies have found that snoring sometimes causes apnea, and the body's necessary ventilation is limited, thereby reducing the partial pressure of oxygen and increasing the partial pressure of carbon dioxide in the body, and even causing a series of serious consequences, until death by suffocation. Snoring with apnea syndrome, also known as sleep apnea syndrome (OSAHS), refers to the interruption of airflow to the mouth and nose during sleep for more than 10 seconds, accompanied by a decrease in blood oxygen saturation. The patient snores d...
