DEVICE FOR PREVENTING A TRAFFIC ACCIDENT AND AN OPERATION METHOD THEREOF, CAPABLE OF PREVENTING A TRAFFIC ACCIDENT DUE TO DROWSY DRIVING BY DETERMINING THE DROWSY DRIVING ON THE BASIS OF OXYGEN CONCENTRATION INSIDE A VEHICLE

摘要

PURPOSE: A device for preventing a traffic accident and an operation method thereof are provided to prevent drowsy driving, vehicle fire, and suicidal ideation by sensing oxygen concentration and smoke generation inside a vehicle.;CONSTITUTION: A device for preventing a traffic accident comprises an oxygen concentration measurement sensor unit(110), a smoke sensor(120), and a control unit(130). The oxygen concentration measurement sensor unit measures oxygen concentration inside a vehicle. The smoke sensor senses the generation of smoke inside or outside the vehicle. The control unit determines the drowsy driving of a driver and the suffocation possibility of a passenger. The control unit performs an operation for preventing the suffocation of the passenger when the suffocation of the passenger is possible. The control unit performs an operation for preventing vehicle fire when sensing smoke inside or outside the vehicle.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Oxygen concentration measurement sensor unit; (120) Smoke sensor; (130) Control unit; (140) Alarm unit; (150) Vehicle window operating unit; (160) Communication unit; (170) Black box;
