Abstract

본 발명은 운전자가 운행중 졸고 있는 상황을 차량측에 설치된 장치에 의해서 인식하여, 운전자가 졸고 있을 때 그 졸음을 방지할 수 있는 졸음 경보 장치 및 이 장치를 이용한 에어백 시스템에 관한 것이다.The present invention relates to a drowsiness alarm device capable of recognizing a sleeping state of a driver while the driver is sleeping by means of a device installed on the vehicle side and preventing the driver from drowsing when the driver is asleep, and an air bag system using the device.

상기 졸음 경보장치는 운전자의 헤드의 동작 상태를 연속적으로 감지하는 적외선 센서(11)와, 운전자의 안면/안구의 상태를 촬영하는 CCD카메라(12)와, 상기 입력 정보 수단(11,12)에 의해서 입력 정보를 입력받아 미리 입력된 알고리듬을 통하여 최종적으로 운전자의 졸음을 인식하여 시스템 전체를 제어하는 마이콤(10)과, 상기 마이콤(10)에서 운전자의 졸음 상태를 판단하면 그 제어 출력에 의해서 제어되는 졸음 경보 수단(20)으로 구성된다.The drowsiness alarm device includes an infrared sensor 11 for continuously sensing the operation state of the driver's head, a CCD camera 12 for photographing the state of the driver's face / eyes, A microcomputer 10 for inputting input information and recognizing sleepiness of a driver through a pre-inputted algorithm to control the entire system; and a microcomputer 10 for controlling the driver And a drowsy alarm means (20).

이것에 의해, 화상 정보로서 감지하여 정확하게 운전자의 졸음 상태를 감지할 수 있다.As a result, it is possible to detect the drowsiness state of the driver accurately by detecting it as image information.
