摘要交通事故的诱发因素很多，据去年年底发布的2016年全国道路交通事故情况显示，在过去的一年中全国范围内发生交通事故接近20万余起，对人们的生活造成了巨大的影响。据不完全统计，其中50%~80%的重大事故是因为疲劳驾驶导致。
人们正在进行相关的疲劳驾驶检测系统的研究，很多产品也都纷纷上市。但到目前为止，所生产出的产品也仅仅用于实验和展览。这些技术存在着很多局限性，难以产品化的原因有很多；因此本课题主要解决基于脑电信号的疲劳判定标准的建立与疲劳驾驶检测报警系统的软硬件设计的问题。47848
疲劳驾驶检测系统包括人体信号的采集系统、信号的处理分析系统和后续的报警系统。我设计的这套脑电信号采集处理系统，有前置模拟放大器的设计，滤波电路和50Hz陷波器，A/D转换和CPU，还有一个报警系统以及HT的显示屏。

Title Fatigue driving detection technology research
Abstract
The causative factor of traffic accidents, released by the end of last year, according to 2016 national road traffic accident situation in the past year, a total of more than 270000 traffic accidents occurred across the country, caused numerous casualties and property losses. According to incomplete statistics, 50% ~ 50% of major accidents due to fatigue driving.
Now many car manufacturers at home and abroad in developed can effectively detect the driver driving state of vehicle equipment, many of the so-called fatigue driving detection equipment has been listed. But so far, to produce a product is only used for experiments and exhibition. These technologies there are many limitations, there are many reasons to the transition; So this topic is mainly to solve the fatigue criterion based on eeg signals establishment and fatigue driving detection alarm system of hardware and software design.
Fatigue test system including the human body signal acquisition system, the signal processing analysis system and the subsequent alarm system. Research and design A kind of brain electrical signal collection and processing system, the hardware part includes the overall design of the circuit, the design of the front analog amplifier, the design of filter circuit, A/D conversion, software part for microcontroller programming, to extract the brain electrical characteristics, through the subsequent alarm system alarm.
Keywords Fatigue driving filter circuit
