| 中文摘要 | 目的研制一套便携式的双通道脑电遥测系统。方法1)脑电放大器,AD8221仪用放大器为前置放大端,精密放大器AD824完成放大、滤波以及电平调整;2)无线传输,采用两片nRF24E1作为无线收发主芯片,该芯片集成8051内核、8通道A/D转换器,通过软件编程实现双通道脑电信号的采集和数据打包。3)电源设计,系统采用锂电池供电,并有电源充放电管理和监测报警电路。结果经测试性能达到要求,可用于便携式脑电信号的采集。结论这套研制便携式脑电遥测系统的方法是可行的,进一步改进后可做成头戴式遥测系统。; Objective To develop a set of portable two-channel EEG radiotelemetry system. Method 1) EEG amplifier: using instrument amplifier AD8221 for preamplifier and precision amplifier AD824 for filtering, amplifying and voltage adjustment; 2) Wireless transmission: this part was based on nRF24E1 that is 2.4 GHz transceiver with embedded 8051 core and 8 input ADC. Software programming was used to realize two-channel data acquisition and encapsulation; 3) Power supply: Li battery was used to provide charging and discharging management and alarm function. Result It was proved experimentally that this system could meet the requirement of a portable EEG acquisition system. Conclusion The design of the portable EEG radio telemetry system is practical and can realize headset system after some improvements. |
