摘要
基于项目教学法的理念,设计了一款单通道脑电控制智能小车的实训系统,包括:脑电信号采集单元、智能小车单元、信号预处理单元及PC机端的信号显示单元。脑电信号采集由TGAM1-R2.4A模块和无线蓝牙模块组成;智能小车由STC12C5A60S2微处理器、电机驱动模块以及无线蓝牙模块组成;信号预处理由STM32F103ZE微处理器来实现;在PC机上采用LabVIEW软件完成脑电信号的存储、显示,对脑电信号做进一步的处理并转换为智能小车的控制信号,实现对小车速度及方向的控制。该系统可用于生物医学工程专业创新实践训练课程。
A training system of single channel EEG control intelligent car is designed based on the idea of engineering project teaching method,including brain electrical signal acquisition unit,intelligent car unit,signal preprocessing unit and signal display unit on PC. EEG signal acquisition unit is composed of TGAM1-R2. 4A module and wireless bluetooth module; The intelligent car is composed of STC12C5A60S2 microprocessor,motor drive module and wireless bluetooth module; Signal preprocessing is realized by STM32F103 ZE microprocessor. The LabVIEW software is used to complete the storage and display of the EEG signal on PC. Further processing is done to EEG signals. Then the result is converted to control signal of intelligent car and transmitted to intelligent car unit to control its speed and direction. This system can be applied to the innovation practice training course of biomedical engineering.
