Small-sized aeration cell electrode, can measure lactic acid in driver's perspiration, ammonia and alcohol content, then by compact radio emitter
Transfer data to research center.Research center judges the degree of fatigue of driver, sends police to driver in time by computer for analysis
Accuse, it is to avoid the generation of vehicle accident.The country also have can effectively the preventing driver traffic violation, contain major traffic accidents " vapour
Report of the car Tachographs " by identification.
The above method reaches practicality and all there is certain difficulty because of such or such problem.With electronic technology
The ARCHEAN.net that develops rapidly all rights reserved, by using state-of-the-art measuring technology, with reference to embedded computer, network
The application of technology, intelligent control technology, to fatigue drive of car monitoring state, reach and reduce the road caused because of fatigue driving
The purpose of road vehicle accident.
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 deviations different from normal driving.Such as：Suddenly the frequency brought to a halt increases, continuous large throttle when
Steering wheel turn to suddenly, the stationarity of gas pedal change etc..With reference to Techniques of Neural Network, fuzzy control and expert it is
Unite, constitute the monitoring of the driving condition to driver, increase the interaction platform with driver, indicate to driver's proposition driving,
Report to the police etc..I on the auto-wave car of oneself made some and attempted, and bore fruit.
