The Research Of Driver Fatigue Detection Warning System Based On Brain-computer Interface

With the development of society and the times, researchers are more and moreattention to intelligent control.The field of Brain-Computer Interface System(BCI)have gained rapid development, a lot of talent and capital began to concentrate in thisarea, this shows that the study of BCI will be rapid progress in this century and gaingreat social and commercial value. Through existing research and theory,we now thatthe BCI System is a channel of the communication of brain and external controldevice, Its successful development can only help those people with reduced mobilityto achieve the purpose of external control, and can also help to improve the lives ofnormal working efficiency, technology has brought us to enjoy the convenience andfun.In this paper we will discuss the study and design the BCI System which can beapplied in everyday life. The main content is divided into the following sections：（1）We have a detailed description of BCI System’concept to the reader, so thatwe understand the working principles and social values BCI Systems.We introducethe mainly advances in research and study abroad of BCI System.We describe brainworks and the generation and transmission of EEG in detail.We describe ourexperiments applied EEG acquisition system-ThinkGear EEG Instrument, itsadvantage is a strong anti-interference ability and carry simplely, you can wave outputα wave, β wave, δ wave, θ wave, γ wave,attention and meditation and so on, thisbrings great convenience for our follow-up study.（2）We study the data format and parse EEG data stream flow TGMA EEGchip for subsequent experiments and software development has laid a good theoreticalbasis.（3）We designed a warning system to detect driver fatigue, which can detect asubject’ EEG in real time and then determine which state, when the subject ismeasured fatigue, driver alarm equipment to work immediately. The development of this system in reducing major highway traffic accident has important practicalsignificance.（4）We have designed a set of BCI external control system, the subject canchange their status through the software system to control the status of the fourexternal devices, external control system for the future BCI research laid thefoundation early.
