The electromagnetic wave of the step S103: the second predetermined state carries out wireless coupling to the eeg signal of the first predetermined state, make the eeg signal of the first predetermined state be adjusted to sleep steady time eeg signal state.
Wherein, first predetermined state is optionally: frequency is that the eeg signal energy of 14-30Hz accounts for more than 80% of eeg signal gross energy, and the amplitude of eeg signal is 30 below μ V, and now brain wave is mainly β ripple, human brain Comparison of Gardening Activities is fierce, and emotion compares anxiety or fear etc.The brain wave of the first predetermined state, except aforesaid feature, can also be contracted to the scope more easily judged in other embodiments.
Second predetermined state is optionally: electromagnetic frequency is 4-7Hz, and amplitude is 20-40 μ V.Electromagnetic wave under this state is close to brain wave θ wave frequency, and cerebral activity is relatively more steady, and under the electromagnetic coupling of this state, the brain wave of aforesaid first predetermined state can tend to be steady gradually.The electromagnetic wave of the second predetermined state can also be in other embodiments the sleep that prestores steady time human body electroencephalogram's ripple signal, and the time-varying magnetic field with eeg signal same waveform will be changed after its power amplification into, after again wireless coupling is carried out to the eeg signal of the first predetermined state, the controlled purposiveness of the eeg signal of the first predetermined state can be made clearer and more definite.
The eeg signal of electromagnetic wave to the first predetermined state that wireless coupling can be understood as the second predetermined state brings out and guides.Scientific experiments confirms, when outer bound pair brain stimulates, likely lures that brain is from a state transfer to another state into.The such as brain wave of current brain is in the wavy state of β, and when the electromagnetic wave of lasting 10Hz stimulates brain a period of time, then brain wave will to the frequency transitions of our input, and induction brain enters relaxation state.
Analyzing and processing is carried out to eeg signal and optionally comprises waveform analysis and spectrum analysis.Waveform analysis analyzes the form of spectral profile, extracts the parameter of characterization graph form, using the similarity of these parameters estimating as wave spectrum similarity.Main method has: 1. fourier transform method, wave spectrum is decomposed into the superposition of different harmonic wave, with each humorous wave amplitude and phase place for parameter characterization Spectral Characteristic; 2. by Chebyshev polynomials, matching is carried out to spectral profile, using Chebyshev polynomials coefficient and their ratio as the parameter of description spectral signature; Spectral resolution is the wavelet of different scale, different frequency composition, with the parameter characterization wave character of these wavelets by 3. small wave converting method; 4. after calculating primitive curve or wavelet transformation, the fractal dimension of wavelet curve describes wave character.Make comparisons by actual measurement wave spectrum with reference to these characteristic parameters of wave spectrum, measure their similarity, the eeg signal gathered can be contrasted with existing electromagnetic wave (eeg signal when such as sleeping steady).Spectrum analysis (also claiming frequency analysis), that Dynamic Signal is analyzed in frequency domain, the result analyzed is spectral line and the curve of the various physical quantitys taking frequency as coordinate, can obtain the frequency spectrum function F (ω) that various amplitude take frequency as variable.Amplitude spectrum, phase spectrum, power spectrum and various spectrum density etc. can be tried to achieve in spectrum analysis.
In step s 102, if eeg signal does not reach aforesaid first predetermined state, then judge that sleep quality does not need to carry out assistant interventional, then repeat step S101, continue to monitor eeg signal.
From the idiographic flow that the present embodiment proposes, whether the method with assisting sleep function that the present embodiment proposes can be steady by the eeg signal condition adjudgement sleep quality got, the need of carrying out assistant interventional.When judging to need to carry out auxiliary treatment, by the electromagnetic wave of stable second predetermined state, wireless coupling being carried out to the eeg signal of the first predetermined state, sleep state is tended to be steady.Compared to supplementary meanss such as broadcasting music of the prior art, hypnosis, electromagnetic wave wireless coupling means of the present invention can not produce the negative effect of other aspects such as noise or light to sleep, but the electromagnetic wave that be there is no impression by human body carries out auxiliary treatment to sleep, treatment means is better.
