基于脑机接口的嵌入式康复器械系统

An Embedded Brain-computer Rehabilitation System

针对脑机接口康复机器人价格昂贵、体积庞大、携带不便、实用化程度不高等缺点,提出了一种嵌入式脑机康复系统。系统使用便携式脑电采集设备Emotiv来接收脑电信号,在树莓派Raspbian系统下通过QT编写数据处理软件用于接收解析脑电信号,同时设计了运动控制、电机驱动、通信等电路,并在此电路的基础上利用PI算法进行电机的控制。实验结果表明:该系统界面操作友好、运行稳定、携带方便,满足主动式康复的实际应用需求。

Most of the EEG-based rehabilitative robots had the problems of high cost,bulky and inconvenient to carry,far from practical application.In view of this,an embedded brain-computer rehabilitation system was proposed,and then the structure of the system was analyzed.The EEG signal was recorded by the portable EEG device Emotiv EPOC＋,and the EEG data processing software was programmed under the Raspbian system.The circuits of motion control,motor driving and communication were designed as well,and the PI algorithm was used to control the motor.The system has been applied in the clinical rehabilitation,and the experimental results show that the system exhibited the characters of friendly human-machine interactions,better reliability,active rehabilitation and facility for mobile carrying.
