摘　　要：设计了一款基于脑电意识的平衡车控制系统,通过提取脑电信号中的专注度信息实现对平衡车的控制。该系统包括脑电采集模块和平衡车控制系统两大部分。脑电采集模块以TGAM模块为核心,实现脑电信号的采集及滤波,得到有效的脑电数据。平衡车控制系统对接收的脑电数据进行进一步处理,根据eSense算法提取专注度及不同频段的脑电波数据,最后根据提取的数据控制小车的行走。脑电采集模块和单片机控制模块之间通过蓝牙进行数据传输。经测试,该系统性能稳定,控制方向准确,为脑机接口技术的进一步推广奠定了基础。This paper designs a balance car control system based on EEG awareness,in which the concentration information is extracted from EEG data to control the movement of the car. The system is consisted of the EEG acquisition module and the balance car control system. The EEG acquisition module takes the TGAM module as the core to realize the acquisition and filtering of the EEG signal so as to obtain the effective EEG data. The balance car control system further processes the received EEG data and extracts the concentration information and EEG data with different frequencies according to the eSense algorithm. Finally,the movement of the car is controlled by the extracted data. The data transmission between the EEG acquisition module and the SCM control module is achieved via Bluetooth. After testing,the system has the advantages of stable performance and accurate control direction,which lays a foundation for further promotion of brain-computer interface technology.
