Research and analyse in 2009 shows that 37.91% traffic accident is as caused by fatigue driving.Occur various fatigues therewith to drive
Alarm set is sailed, the mode and algorithm that fatigue judges are increasingly mature.Zhejiang Geely Automobile Research Institute Co., Ltd 2010 exists
Patent《A kind of fatigue driving method for early warning》（101986359 A of patent No. CN）In propose a kind of fatigue driving method for early warning：
When engine ignition switch, system brings into operation in the open state, and system is according to continuously driving mileage parameter S and rest
The relativeness of time parameter T determines whether to alarm.2011, Zhongxing Microelectronci Co., Ltd., Beijing was it is also proposed that patent
《Method for detecting fatigue driving and device》（102085099 A of patent No. CN）, the patent provides a kind of fatigue driving detection sides
Method, including positioning driver's eyes；Using the eye image of the image capturing system capture driver with infrared launcher
Data；The number of eyes closed and time in the unit interval are calculated according to the eye image data of capture；According to what is calculated
Whether the number of eyes closed and time judge driver in fatigue state in unit interval.But in existing patent of invention
The inner link of driver and detection device is all not carried out, while does not also have self-powered technology.These prior arts use
Time control or visual spatial attention, can not realization device and driver state of mind direct dialogue, cause error in judgement；In addition,
Due to the problem of lacking self-powered technology, being inevitably happened at dead battery in driving procedure, cause detection device that can not work, go out
It now steals and stops phenomenon, be delayed the instant alerts to driver, lead to a disaster.
The content of the invention
The purpose of the present invention is in view of the deficiencies of the prior art and provide a kind of self-powered Grazing condition fatigue driving carry
