(8-2), when in next interval T3, each electrode of 1 group of electrode of right part is positive level, each electrode of 1 group of electrode of left part is 0 level; Return step (8-1).
9. the control method being applicable to the ocular region massaging device of pseudomyopia according to claim 7, it is characterized in that, described micro processor loop chooses t
i-dmoment is to current time t
ibetween EEG signals S (t), S (t) is inputted in accidental resonance model, accidental resonance model is resonated, calculate resonance time signal to noise ratio snr; Comprise following concrete steps:
S (t) is inputted the accidental resonance model prestored in memory by microprocessor
in;
Wherein, x (t) is the displacement of vibration particle, and Ω is angular frequency, f
0be signal frequency, A is constant, r and ω is the attenuation quotient of setting and the frequency of linear oscillator particle respectively, and c is the signal adjustment coefficient of setting, and b is the quadratic noise ξ of setting
2t the coefficient of (), ξ (t) is three discrimination noises, and { dismutation of noise follows Poisson distribution to ξ (t) ∈ for-a, 0, a}, a > 0, and its probability distribution is p
s(a)=p
s(-a)=q, p
s(0)=1-2q, wherein 0 < q < 0.5;
Noise average and dependency follow < ξ (t) >=0, < ξ (t) ξ (t+ τ) >=2qa
2e
-λ τ;
Wherein λ is correlation ratio, and the glacing flatness of three discriminations noise ξ (t) is
When model resonates, particle produces resonance in certain position, and this angular frequency Ω, attenuation quotient r, correlation ratio λ, coefficient b, constant a, q determine;
Microprocessor utilizes formula
calculate and obtain the output signal-to-noise ratio SNR corresponding with S (t).
10. the control method being applicable to the ocular region massaging device of pseudomyopia according to claim 7 or 8 or 9, is characterized in that, described A is 39 DEG C to 42 DEG C.
