八通道视觉诱发脑电采集系统设计及实现
Design and Implementation of Eight Channels Visual Evoked EEG Signals Acquisition System
摘要
Abstract
In order to solve the problem of low SNR in EEG and meet the requirement of the development of EEG acquisition system,a system is designed to acquire visual evoked EEG signals,which is based on chip ADS1299 of TI Company.Original signals are filtered and conditioned through preprocessing circuit,and then the preprocessed EEG signals are converted to digital signals through 24-bit high-precision chip ADS1 2 9 9 ,finally,the digital signals are transmitted to PC via a USB to serial module;The PC software is programmed by Java to realize the real-time display and storage of EEG signals;Left and right hand motor imagery paradigm is designed to record presentation time,simulation type and behavioral data.Feature ex-traction and classification methods are used on the left and right hand motor imagery visual evoked EEG signals.A BP neural network classifier is used in this paper and the classification rate is as high as 70%.关键词
