摘要 脑机接口(BCI)系统中存在着各种干扰,工频(50Hz)是其中最重要的干扰之一;通过对测量信号线配置和共模干扰等关键问题的讨论,分析了工频对BCI系统中脑电信号采集过程的影响机理;然后对解决工频影响的常用技术进行了研究,并着重阐述了使用主动电极以及前置脑电采集装置在抑制工频干扰方面的优势。 Mains power supply (50Hz) is one of the most significant disturbances in Brain-computer interface (BCI) systems. By discussing the measurement cables arrangement and the common-mode voltage interferences, the disturbance of mains power supply to the Electroencephalographic (EEG) measurements in BCI systems is analyzed and several general techniques are introduced for interferences depression, then the advantages of using active electrode and the pre-recording EEG equipment for inhibiting the interferences is addressed.
