分布式脑电信号采集系统研究

Study on Distributed EEG Signal Acquisition System

通过脑电信号对学生学习状态进行分析是一种先进、客观的新方法。目前对脑电信号的采集还处在单对单的形式,不适用于多人脑电信号的同时采集的学习情景。因此,本文提出了一种可以同时采集多人脑电信号,并且通过无线方式汇总的分布式脑电信号采集方案。测试结果表明,所设计系统可以同步采集多人脑电信号,并进行存储分析,较好地反应了学生的学习状态。

The analysis of students’ learning status through EEG signals is an advanced and objective new method. At present, the collection of EEG signals is still in the form of a single-to-one, and is not suitable for the learning scenarios of simultaneous acquisition of multi-human EEG signals. Therefore, this paper proposes a distributed EEG signal acquisition scheme that can simultaneously collect multi-human EEG signals and summarize them wirelessly.
