摘要
该研究介绍了一种便携式多通道脑电信号采集系统,系统主要由脑电电极连接座、信号调理电路、脑电采集部分、主控MCU与电源部分组成,采用低功耗脑电采集前端ADS1299和STM32组成信号采集和数据通信部分,所采集的脑电信号可传输至PC端进行实时显示。经过相关测试、该系统体积小、功耗低、信噪比高,可满足便携式可穿戴医疗设备的要求。
This study introduces a portable multi-channel EEG signal acquisition system.The system is mainly composed of EEG electrode connector,signal conditioning circuit,EEG acquisition part,main control MCU and power supply part.The low-power EEG acquisition front-end ADS1299 and STM32 are used to form the signal acquisition and data communication part.The collected EEG signal can be transmitted to the PC for real-time display.After relevant tests,the system has small volume,low power consumption,high signal-to-noise ratio,and meets the requirements of portable wearable medical devices.
