In the book, the importance of EEG acquisition and pre-processing under centrifuge G acceleration for the subsequent processing is firstly introduced, that is the necessity of EEG acquisition and pre-processing is introduced. Then the acquisition and pre-processing technology of EEG signal under centrifuge G acceleration is highlighted. At the same time, development and application of EEG, and the research status of EEG acquisition technology and filtering technology at present are made a more comprehensive introduction. This study conducts human experiments combining the current existing problems in actual flight and centrifuge training by using high-performance human centrifuge in our country, and synchronously obtains physiological signal data of EEG, ECG, ear pulse, and brain blood pressure and so on by using different devices and methods. Due to the particularity of experimental equipment and the high risk of human experiments, the experimental implementation has a greater difficulty. This study establishes an acquisition scheme for synchronously and real-time acquisition of physiological signals such as EEG, brain blood pressure, ear pulse, and ECG and so on by using different devices and methods under +Gz acceleration on human centrifuge. And combining the characteristics of changes of various physiological signals under +Gz acceleration, a new experimental research method for obtaining and changing characteristics of EEG signal under +Gz acceleration on a three-axis high-performance human centrifuge is proposed, laying a foundation for subsequent the related research on EEG and other physiological signals.
