1. An electroencephalograph device, comprising:
a stimulation unit, configured for generating a stimulation signal and apply the stimulation signal to a human body; and
an acquisition unit, configured for acquiring physiological electrical signals of a human brain, wherein
the acquiring, by the acquisition unit, the physiological electrical signals of the human brain comprises: when the stimulation unit does not apply the stimulation signal to the human body, acquiring, by the acquisition unit, the physiological electrical signals of the human brain according to a first acquisition parameter; and when the stimulation unit applies the stimulation signal to the human body, acquiring, by the acquisition unit, the physiological electrical signals of the human brain according to a second acquisition parameter,
wherein the first acquisition parameter is different from the second acquisition parameter, wherein the first acquisition parameter and the second acquisition parameter are the same parameter but have different values,
the first acquisition parameter comprises at least one of a first acquisition frequency and a first signal gain;
the second acquisition parameter comprises at least one of a second acquisition frequency and a second signal gain;
wherein the first acquisition frequency is lower than the second acquisition frequency and the second signal gain is lower than the first signal gain, wherein
the acquiring, by the acquisition unit, the physiological electrical signals of the human brain further comprises: when the acquisition unit determines that the stimulation unit intends to apply stimulation, adjusting, by the acquisition unit, the first acquisition frequency of the acquisition unit into the second acquisition frequency, wherein
when the stimulation unit applies the stimulation signal to the human body, the acquiring, by the acquisition unit, the physiological electrical signals of the human brain according to the second acquisition parameter comprises: judging, by the acquisition unit, whether an amplitude of the acquired signals exceeds a set threshold; and if yes, adjusting, by the acquisition unit, the first signal gain of the acquisition unit into the second signal gain.
