摘　　要：为提升传统听觉诱发电位测量设备的移动性和无线通信能力,研究设计并实现了一种新型的基于蓝牙通信的听觉诱发电位测量系统。该系统包含一个基于STM32F4微控制器的脑电信号采集模块与能够配合脑电模块实现稳态听觉诱发电位采集的脑电帽。上位机通过蓝牙向采集模块发送控制指令,以实现脑电信号的实时采集和分析。实验验证了使用不同频率的Click声音刺激下的测试,并通过频谱分析获取了真实的频率响应,从而证实了其测量的准确性和系统的稳定性。In order to improve the mobility and wireless communication ability of traditional auditory evoked potential measurement equipment,a novel auditory evoked potential measurement system based on Bluetooth communication was designed and implemented in this study.The system includes a EEG signal acquisition module based on STM32F4 microcontroller,and a EEG cap that can cooperate with the EEG module to realize steady-state auditory evoked potential acquisition.The upper computer sends control commands to the acquisition module through Bluetooth to realize real-time EEG signal acquisition and analysis.The experiment verifies the test under different frequencies of Click sound stimulation,and the real frequency response is obtained by spectrum analysis,thus confirming the accuracy of the measurement and the stability of the system.
