Embodiment 1

[0063] The working principle diagram of the sleep detection and sleep assistance method implemented in this embodiment is as follows figure 1 As shown, the position of the signal acquisition electrode is as follows figure 2 shown. Generally speaking, the music used to relax the mood and adjust the mood is two types of classical music or light music with brisk rhythm, but considering that different people have different feelings about music, the music playback system used in this embodiment allows Users can add their favorite music and adjust the playback order. Studies have shown that sound is transmitted in the form of vibration, and people listen to music through the whole body, so the music playback system of this embodiment plays music according to the volume set by the user through the 2.1-channel sound system, and the music effect is better. Before use, the user puts on the electrode cap, fixes the electrode position, then opens the operation interface of the music pl...

Embodiment 2

[0088] A sleep detection and sleep assistance device based on EEG signals disclosed in this embodiment includes the following modules:

[0089] The EEG signal acquisition module is used to collect the EEG signals of the human body;

[0090] The EEG signal processing module is used to process the EEG signal, including a component extraction unit and a feature extraction unit, wherein the component extraction unit extracts different components of the EEG signal, and the feature extraction unit is aimed at Different components are subjected to feature extraction respectively, and the feature is the energy of different components in the EEG signal, and the energy of each component is defined as the square sum of the signal amplitude:

[0091] E = Σ i = 0 N x i 2

[0092] where x i Represents the...

Abstract

The invention discloses an EEG (electroencephalogram) based sleep detection and sleep aid method and device. The EEG based sleep detection and sleep aid method includes the steps of S1, collecting human single-channel EEG; S2, processing the EEG by extracting components and features; S3, assessing energy gradient according to included angle of the previous energy vector and the next energy vector; and S4, testing sleep state in real time by assessing change of states according to the assessment control criterion so as to form an application control decision to control a music play system. The features refer to energy of different components of the EEG, and energy of each component is defined as quadratic sum of signal amplitude. The method, which is capable of analyzing sleep states by means of on-line energy change assessment process and achieving sleep aid, is practical and universal, and further, is convenient and flexible as the aid process can be modified personalizedly according to personal preference.

Description

technical field [0001] The invention relates to the technical field of sleep aid research, in particular to a method and device for sleep detection and sleep aid based on electroencephalogram signals. Background technique [0002] Sleep is a very important physiological activity. Through sleep activities, the human body can eliminate fatigue and restore physical strength, improve its own immunity, improve the hematopoietic ability of the spleen and bone marrow, and keep the brain clear and responsive. The quality of sleep quality directly affects people's health, study, life and work. However, the pace of life of modern people is accelerating day by day, and they are under increasing pressure in work and life, and the incidence of various sleep diseases is also increasing. Among them, insomnia is the most common sleep disorder. Long-term lack of sleep can easily lead to poor mental state, lack of concentration, and may also lead to anxiety, depression and other mental dis...
