【摘要】：腦-機(jī)接口(BCI)系統(tǒng)是通過腦電(EEG)信號(hào)實(shí)現(xiàn)人和計(jì)算機(jī)等設(shè)備之間的交流和控制的系統(tǒng)。本文闡述了基于BCI技術(shù)的無線智能家居系統(tǒng)的工作原理,利用單片機(jī)、LED燈組成視覺刺激器誘發(fā)得到穩(wěn)態(tài)視覺誘發(fā)電位(SSVEP),再利用在LabVIEW平臺(tái)上的功率譜變換方法實(shí)時(shí)處理不同頻率刺激下產(chǎn)生的EEG信號(hào),將其轉(zhuǎn)化為不同的指令,由無線射頻設(shè)備收發(fā)控制命令,實(shí)現(xiàn)家居設(shè)備的實(shí)時(shí)智能控制。實(shí)驗(yàn)結(jié)果表明,10名受試者的正確率均達(dá)到100%,單個(gè)設(shè)備的平均控制時(shí)間為4s,實(shí)現(xiàn)了家居設(shè)備的智能控制。
[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.
