6. a kind of brain wave acquisition handles regulating system according to claim 5, which is characterized in that the preset percentage is
0.8%-2%。
7. a kind of brain wave acquisition handles adjusting method, regulating system is handled for brain wave acquisition as claimed in claim 5, it is special
Sign is, comprising the following steps:
Step S1, using the simulation EEG signals of brain wave acquisition device acquisition human body head；
Step S2 is AD converted the EEG signals using control circuit board, obtains digital brain electrical signal；
Step S3 receives the digital brain electrical signal using host computer, and carries out conversion process to the digital brain electrical signal, obtains
It is carried out respectively with corresponding parameter preset pair to multiple and different brain state parameters, and by multiple brain state parameters
Than, when the difference of some or multiple brain state parameters and the corresponding parameter preset absolute value with it is described pre-
When the ratio of setting parameter is greater than preset percentage,
Training Control order is sent to calling module；
Step S4 receives the control command using calling module, and corresponding from server calls according to the control command
Animation；
Step S5 shows the animation by display, while the brain state parameter changes, with the brain state parameter
Corresponding animation also shows different pictures；
Step S6 adjusts brain state parameter by viewing animation, until brain state parameter and corresponding parameter preset
The absolute value of difference and the ratio of the parameter preset are not more than preset percentage.
8. a kind of brain wave acquisition handles adjusting method according to claim 7, which is characterized in that the preset percentage is
0.8%-2%。
