Abstract

The invention provides a brainwave signal acquisition device and a preprocessing method thereof. The acquisition device comprises an elastic arc-shaped headband and a brainwave acquisition sensor arm connected to the elastic arc-shaped headband at both ends, wherein one end of the brainwave acquisition sensor arm is connected to a wireless transceiver module, and two ends of the elastic arc-shaped headband are connected to a jaw-fixing elastic soft belt used for making the elastic arc-shaped headband cling to the brain surface tightly; The brainwave acquisition sensor arm is electrically connected to at least three brainwave acquisition electrodes. The acquisition device has the advantages of simple structure, low cost and easy popularization. The brainwave signal preprocessing analysis uses analysis methods of intelligent blind source signal separation and intelligent learning algorithm to extract features, and solves the difficult problems that the signals collected by a simple brainwave signal acquisition device have too large noise interference and low precision to separate the real brainwave signals.

Description

technical field [0001] The invention relates to the technical field of brain wave acquisition, in particular to a brain wave signal acquisition device and a preprocessing method. Background technique [0002] In 1929, German neuropsychiatrist Hans Berger published the first research report on "human electroencephalogram", and people began to study the brain signal (electroencephalogram, EEG). The study of brain waves has made remarkable progress in recent years with advances in electronics and signal processing technology. [0003] Brain wave acquisition technology is currently widely used in the fields of intelligent control, medical treatment, and brain-computer interface. At present, most of the brain wave acquisition devices are medical helmet-type structures, which are inconvenient to wear, difficult to adjust the signal acquisition position, and expensive. If the signal collected by the full helmet is not used, the noise interference will be large and inaccurate, mak...
