【摘要】：脑-机接口(BCI)系统是通过脑电(EEG)信号实现人和计算机等设备之间的交流和控制的系统。本文阐述了基于BCI技术的无线智能家居系统的工作原理,利用单片机、LED灯组成视觉刺激器诱发得到稳态视觉诱发电位(SSVEP),再利用在LabVIEW平台上的功率谱变换方法实时处理不同频率刺激下产生的EEG信号,将其转化为不同的指令,由无线射频设备收发控制命令,实现家居设备的实时智能控制。实验结果表明,10名受试者的正确率均达到100%,单个设备的平均控制时间为4s,实现了家居设备的智能控制。
[Abstract]:Brain-computer interface (BCI) system is a system which realizes the communication and control between human and computer by means of EEG signal. This paper describes the working principle of wireless smart home system based on BCI technology. The steady-state visual evoked potential (SSVEP) is induced by a single chip microcomputer LED lamp. The power spectrum conversion method on the LabVIEW platform is used to process the EEG signals generated by different frequency stimuli in real time, and the signals are converted into different instructions. The real-time intelligent control of home equipment is realized by radio-frequency equipment receiving and sending control commands. The experimental results show that the correct rate of each of the 10 subjects is 100 and the average control time of a single device is 4 s. The intelligent control of household equipment is realized.
