In " road traffic law " that China is new, for safeguarding traffic safety, also expressly provide drive speed, continuously
Driving time etc..More external transportation developed countries also formulate the unification of the motherland regulation of this respect.Fatigue driving is highway
" stealthy killer " on car steering particularly highway, according to ASSOCIATE STATISTICS, from a large amount of analyses of cases of vehicle accident
The conclusion haveing is thought: the driver accounts for the 20% of vehicle accident sum because of the road traffic accident that fatigue driving is caused.And it is tired
Labor is driven in the reason of dead vehicle accident and but accounts for 22%-30%, ranks first, thus in the reason of dead vehicle accident
The fatigue driving hazardness to traffic safety can be thought.
In addition to the construction of legal rules, automobile vendor both domestic and external also designs various instrument and equipment for fatigue driving monitoring, and one
Planting the infrared ray eyeball scanner for fatigue driving to succeed in developing in the U.S., this eyeball scanner profile is the most same small-sized
Video camera, uses also very convenient, as long as it is arranged on instrumental panel, alignment lens driver, scanner will be sent continuously
Infrared signal scans the white of the eye part in driver's eyeball, judges degree of fatigue simultaneously and sends " ramp to stop ", " has a rest
The caution signals such as once ".Industry giant's long-term R & D such as Reynolds, Nissan overcomes fatigue driving one monitoring system, because of theoretical skill
Art applied defect still cannot business promotion.The fatigue warning device that Toyota Company of Japan develops, as long as driver turns in manipulation
There have during dish to be the most blunt, or pulse has some ANOMALOUS VARIATIONS, and this device just can measure these reactions, and gives a warning, and makes seat cushion
Vibration or self-actuating brake.
The fatigue tester that Tokyo Univ Japan develops, can be worn in the wrist of driver.Equipped with one inside this tester
Small-sized aeration cell electrode, can measure the lactic acid in driver's perspiration, ammonia and alcohol content, then by compact radio emitter
Transfer data to research center.Computer for analysis is passed through in research center, it is determined that the degree of fatigue of driver, sends police to driver in time
Accuse, it is to avoid the generation of vehicle accident.Domestic also have can effectively the preventing driver traffic violation, containment major traffic accidents " vapour
Car Tachographs " by the report identified.
The above method, because of such or such problem, reaches practicality and all there be difficulties involved when.Along with electronic technology
The ARCHEAN.net that develops rapidly all rights reserved, by use state-of-the-art measuring technology, in conjunction with embedded computer, network
The application of technology, intelligent control technology, to fatigue drive of car monitoring state, reach to reduce the road caused because of fatigue driving
The purpose of road vehicle accident.
Along with the increase of continuous driving time, monitor controller is automatically into fatigue driving monitoring state, if driver has tired
Labor symptom, will necessarily reflect the deviation different from normal driving.As: when the frequency increase brought to a halt suddenly, continuous large throttle
Steering wheel turn to suddenly, the stationarity change etc. of gas pedal.In conjunction with Techniques of Neural Network, fuzzy control and expert it is
System, forms the monitoring to the driving condition of driver, increases the interaction platform with driver, to driver propose to drive instruction,
Report to the police.I had made some on the auto-wave car of oneself and had attempted, and bore fruit.
