The method warned using above-mentioned automobile safety alarm system to fatigue driving is included：
Step 1: the analog video image of infrared camera collection driver's face, Video Decoder is by the analog video
Image is converted to digital picture and is sent to main core microprocessing unit.
Step 2: main core microprocessing unit is handled the digital picture, when calculating eyes closed degree and unit
Percentage P shared by the interior eyes closed time, and P values and the default class of A, B, C tri- are represented to the threshold value of different fatigue state
It is compared judgement：If P ＜ A, then it represents that driver all goes well, and main core microprocessing unit does not export serial ports control life
Order, return continue executing with step 1；If A≤P≤B, then it represents that driver is in slight fatigue state, main core microprocessor list
Member output serial ports control command, and Vehicle Controller is sent to by com interface, Vehicle Controller control voice reminding module is carried out
Voice reminder, it is proposed that driver is taken a quick nap, and Vehicle Controller is communicated by CAN with CAN, controls car
Window is opened, and to slow down the sense of fatigue of driver, is then back to and is continued executing with step 1；If B ＜ P ＜ C, then it represents that at driver
In general fatigue state, main core microprocessing unit exports serial ports control command, and is sent to Vehicle Controller by com interface,
Vehicle Controller control voice reminding module reports the general fatigue information of driver, improves driver and jeopardizes life to fatigue driving
The cognition degree of life, Vehicle Controller are communicated by CAN with CAN, control direction disk and seat vibration, with
It is recommended that driver not continue to drive, traffic accident is prevented, is then back to and continues executing with step 1；If P >=C, table
Show that driver is in severe fatigue state, main core microprocessing unit exports serial ports control command, and is sent to car by com interface
Set controller, Vehicle Controller are communicated by CAN with CAN, and double get out of the way of control opens simultaneously force disconnect oil
Road, so that vehicle automatic stopping stops working and warns other passing cars to pay attention to avoiding, Vehicle Controller passes through WIFI communication modules
Interconnected with mobile phone, the severe fatigue information of driver is sent to nominator using mobile phone, to ensure the life security of driver,
Avoid accident from further expanding, then terminate.
The present invention compared with prior art, has the effect that：
（1）Using the analog video image of infrared camera collection driver's face, system all weather operations can be met
Requirement, even if light in driving cabin is even unglazed for low-light, system can also be detected normally, and belong to contactless
Mode, do not interfere with the operation of driver, occupation mode flexibly, it is comfortable, be easily easily accepted by a user.
（2）The fatigue state of driver is divided into three classes, when driver is slightly tired, carries out voice reminder, it is proposed that drive
The person of sailing takes a quick nap, while opens vehicle window, slows down driver fatigue sense；In driver's general fatigue, the one of driver is reported
As fatigue state, improve driver to the cognition degree of fatigue driving threat to life, while travel direction disk and seat vibration, it is proposed that
Driver not continue to drive, and prevent traffic accident；In driver's severe fatigue, open double sudden strains of a muscle and cut off oil circuit, make
Vehicle automatic stopping stops working and warns other passing cars to pay attention to avoiding, while sends information and notify nominator, has ensured driving
The life security of member, is avoided that accident further expands.Its alarming effect is notable, practical, can effectively prevent due to driving
Driving accident caused by the person's of sailing fatigue driving, improve travel safety.
