Sound sleep control system with sleep state feedback in closed loop path and method thereof

Abstract

The invention relates to a sound sleep control system with sleep state feedback in a closed loop path and a method thereof, which include a sensor, a controller, and an actuator; wherein the sensor isa brain wave detection device, which is used for having a real-time collection of an EEG signal of human body sleep and sending the EEG signal to the controller; the controller is a computer, which is used for identifying a stage of the human body sleep according to the EEG signal, generating an acoustic model similar to a sleep spectrum of the next stage, and sending the model to the actuator; the actuator is a player of hypnotic sound, which is used for playing the hypnotic sound. The sound sleep control system with the sleep state feedback in the closed loop path and the method thereof arecharacterized in that based on a feedback control idea, the sleep control system is established with human body sleep states as control object and the EEG signal as a feedback quantity; based on studying features of the EEG signal frequency in the sleeping process, a control sound base and sleep control rules are established according to a bio-resonance principle; and have the advantages that thesleep control system based on the sleep control rules is capable of progressively controlling the human body into deep sleep, and sleep quality is greatly increased.

Description

technical field [0001] The invention relates to the field of human sleep control, in particular to a sound sleep control system and method for sleep state feedback in a closed-loop path. Background technique [0002] With the continuous acceleration of the pace of social life, increasingly fierce competition, and the increasing pressure of survival, people's sleep quality began to have problems. According to the published third edition of the International Classification of Sleep Disorders, sleep disorders have increased from the previous 92 types. There are 102 kinds, of which insomnia symptoms still account for a large proportion. According to the survey, 38.6% of the population in my country suffers from sleep disorders to varying degrees, and the incidence of sleep disorders in the elderly group is as high as 56%. Patients with insomnia may experience many uncomfortable symptoms. Long-term insomnia will lead to the decline or even disappearance of various body functions, ...

Problems solved by technology

[0005] First, most researchers focus on exploring which physical method is more effective in improving sleep from the perspective of application, and rarely study the mechanism of sound and other physical media affecting sleep from a theoretical perspective.

Therefore, the research of physical methods only relies on experiments to explore, and lacks direction and development potential;

[0006] Second, sleep, as a part of brain activity, is a complex physiological process that includes several independent sleep states. During the whole sleep process, the brain is alternately or cyclically in these several sleep states. Therefore, in Blindly applying physical hypnosis without knowing the current state of the brain, the effect is difficult to guarantee;

[0007] Third, since the sleep process of the human brain is a multi-branched and progressive dynamic process, the current sleep methods cannot control the sleep process according to a certain sleep "path", but simply assume that the process is "awake" and "sleep". 2 states of creep
