摘　　要：设计了一种基于单片机、无线芯片n RF24L01和TFT液晶显示屏的便携式脑电无线采集系统,系统控制器采用STC12C5A60S2单片机。发送端的单片机对预处理后的脑电信号进行采集和存储,通过n RF24L01芯片进行无线传输,接收端单片机再将信号波形送至液晶显示屏显示并进行进一步的分析。该系统不需要采用PC机,因此具有体积小、轻便、功耗低等特点。The design of portable wireless acquisition system for EEG signal is introduced. The single chip microcomputer STCI2C5A60S2 was used to acquire the amplified and fihered EEG signal. The acquired EEG signal data was transmitted by nRF24L01, the data was received and send to the TFT LCD for display, and analized by the receiver. PC machine do not be need any more in this system, so the system has the characteristic of low power consumption and is small and portable.
