Sleep monitoring and regulation system based on phase array microphone

Abstract

The invention discloses a sleep monitoring and control system based on a phase array microphone, comprising: a directional sound pickup unit, which includes an acoustic monitoring microphone phase array, and a signal separation and extraction module; an intelligent analysis unit, which separates and extracts signals according to the The sleep breathing acoustic signal of the monitored object obtained by the module determines the breathing type of the monitored object; the personalized sleep aid adjustment and sleep monitoring unit includes a respiratory monitoring module, an external microphone phase array, a sleep aid module and an alarm module. The sleep monitoring and regulation system based on the phase array microphone of the present invention has no load on the human body at all, can achieve sleep monitoring and regulation without wearing, can truly realize zero load, personalized sleep monitoring and sleep regulation, and overcome the existing problems of existing products Discomfort caused by needing to wear; the invention can improve the accuracy of sleep monitoring judgment; the invention can accurately give personalized acoustic stimulation to the monitored object based on the monitoring results, promote sleep and improve sleep quality.

Description

technical field [0001] The invention relates to the technical field of sleep monitoring and regulation, in particular to a sleep monitoring and regulation system based on a phase array microphone. Background technique [0002] According to statistics from the World Health Organization, about 38% of the world's population suffers from sleep problems, and the quality of sleep directly determines people's physical and mental health, daytime cognitive function, and work efficiency. Long-term sleep disturbance will not only induce a variety of physical and mental diseases in individuals, but also bring a heavy economic burden to society. [0003] At present, the combination of subjective questionnaire and objective sleep monitoring is mostly used in sleep quality assessment and sleep disorder screening. Among them, polysomnography (PSG) is the only standard for diagnosing sleep disorders and systematically judging objective sleep conditions. It includes pressure airflow (snoring...

AI Technical Summary

Problems solved by technology

Among them, polysomnography (PSG) is the only standard for diagnosing sleep disorders and systematically judging objective sleep conditions. It includes pressure airflow (snoring) and thermal airflow, zRIP respiratory effort (chest / abdomen), body position, and SpO 2 The measurement of (pulse wave and pulse rate) is cumbersome to use, there is a sense of restraint, the sensor is easy to fall off, and zero-load sleep monitoring cannot be realized

Due to the expensive PSG equipment, the need for professional and technical personnel to operate, and the manual interpretation of the report is extremely time-consuming, the monitoring needs to be carried out in the hospital, which cannot reflect the real sleep status of the patient at home.

[0004] In addition, some current zero-load sleep monitoring products still have many problems, such as still need to wear related equipment, can not achieve true zero-load; monitoring accuracy is low

For sleep control, existing products such as head-mounted sleep monitoring equipment, smart mattresses, radar balls, and smart ventilators still have defects such as uncomfortable wearing and inability to truly achieve zero-load control.
