摘　　要：介绍一种基于C8051F340单片机的EEG信号采集系统。该设计采用高速、高集成度的C8051F340单片机控制A/D转换器ADS8344和无线收发器ADF7020实现了EEG信号数字采集和无线数据传输;同时采用了C8051F340内嵌USB功能控制器解决接收器与计算机之间USB数据传输等问题。测试结果表明,该EEG信号数字采集系统具有集成度高、功耗低、体积小和操作方便等特点,具有良好的应用前景。An EEG acquisition system using C8051F340 is introduced. In order to realize the acquisition and wireless transmission,the A/D converter ADS8344 and trans receiver ADF7020 are all controlled by C8051F340,which is of a high speed and high integrated MCU. In addition,the USB function controller using embedded C8051F340 is adopted in the design to solve the transmission problem between the receiver and computer. The results indicate the designed system has the advantage of high integration,low power,small size and that simple operation has application prospects.
