摘要
为了解决传统听觉诱发电位仪的便携性、无线传输问题,设计一种基于蓝牙的听觉诱发电位测量系统。该系统的下位机采用以STM32F4为核心的独立声音刺激器,配合以ATmega328P为处理器的脑电采集器的设计。使用Visual C#开发的上位机通过蓝牙发送指令给下位机,实现刺激声的播放、脑电数据的采集和处理。该系统经过充分测试,并给出一个短声串的诱发反应实验,其结果与理论一致,证明了系统的可靠性及稳定性。
An auditory evoked potential measurement system based on Bluetooth is designed to resolve the portability and wireless transmission problems of the traditional auditory evoked potentiometer. In the lower computer of the system,the independent sound stimulator taking STM32 F4 as the core is adopted,and the design of EEG collector taking ATmega328 P as the processor is supplemented. The upper computer developed by using Visual C# is adopted to send instructions to the low computer via Bluetooth,so as to realize the play of stimulated sound,and the acquisition and processing of EEG data. The system was fully tested,and a click-train evoked response experiment was performed. The results are consistent with that of the theoretical analysis,which proves the reliability and stability of the system.
