Automatic analysis system and method for data acquisition validity of electroencephalograph

The invention discloses an electroencephalograph data acquisition validity automatic analysis system and method, on one hand, an electroencephalogram-near infrared dual detection mode is introduced, and the structure of a measurement unit is improved to adapt to and conveniently realize dual detection, and on the other hand, an electroencephalogram data preprocessing mode is optimized, and clutter pollution is greatly removed. When data verification and analysis are carried out, different validity analysis means are formulated for theta waves, beta waves and alpha waves, a stimulation mechanism and an artificial feedback mechanism are introduced, validity is verified from the two aspects of data and behaviors, and on the premise that system burden and cost are not increased too much, the validity analysis efficiency is improved. And meanwhile, multiple validity verification modes are realized, and the data acquisition validity automatic analysis efficiency and the result credibility are remarkably improved. 本
