It is invented so as to be prevented to be mounted on a conventional vehicle can greatly contribute to the safety of the driver.
Description
제1도는 본 발명에 따른 운전자 졸음 감지장치의 시스템 구성을 나타낸 시스템 구성도이다.1 is a system configuration diagram showing the system configuration of the driver drowsiness detection apparatus according to the present invention.
본 발명은 졸음 감지장치에 관한 것으로, 특히 운전자가 자동차 운행시 졸음등에 의해 자동차의 속도가 저하될 경우 감지장치가 이를 감지하여 여러 가지의 장치를 작동시키면 운전자의 지각이 환기되어 여러 가지 사고를 미연에 방지할 수 있도록 발명된 것으로 종래의 자동차에 장착되어 운전자의 운전에 크게 기여할 수 있게 될 것이다.The present invention relates to a drowsiness detecting device, and in particular, when the driver's speed decreases due to drowsiness, the driver detects this and operates various devices to ventilate the driver's perception, thus preventing various accidents. Invented so as to prevent it will be mounted on a conventional vehicle will be able to contribute significantly to the driver's driving.
본 발명은, 통상 운전자가 도로 주행시 교통정체로 인해 발생되는 졸음등으로 속도의 저하등 예기치 못한 사고의 결과를 방지하기 위한 운전자 졸음 감지장치를 제공하는 것을 그 목적으로 한다.It is an object of the present invention to provide a driver drowsiness detection device for preventing a result of an unexpected accident such as a drop in speed due to a drowsiness caused by a traffic jam when a driver drives a road.
상기 목적을 달성하기 위한 본 발명은, 운전자의 자동차와 앞차와의 거리를 측정하기 위한 레이저 센서와, 운전자의 졸음등에 의해 자동차의 속도가 저하되는 것(일정 이상의 시간)을 감지하기 위한 스피드 센서, 일정이상의 시간을 감지하기 위한 타이머, 운전자가 졸음 감지장치 시스템을 온/오프 하기 위한 온/오프 스위치 및, 레이저 센서와 스피드센서 및 타이머의 동작을 판단하여 콘트롤 하는 콘트롤러 등에 의해 구성된다.The present invention for achieving the above object, the laser sensor for measuring the distance between the driver's car and the front vehicle, the speed sensor for detecting that the speed of the vehicle is reduced (time or more) by the driver's drowsiness, etc., And a timer for detecting a predetermined time, an on / off switch for the driver to turn on / off the drowsiness detection system, and a controller for determining and controlling the operation of the laser sensor, the speed sensor, and the timer.
상기와 같이 구성된 본 발명은, 운전자의 자동차가 저속운행시 스피드 센서에서 감지된 속도로 앞차와의 거리가 일정 이상으로 떨어질 경우와 타이머에 의한 시간이 일정 이상일 경우에 운전자의 졸음으로 판단하여 콘트롤러에서 콘트롤 하여 경보음, 경고등 및 오디오를 통하여 운전자의 지각을 환기시키도록 작동한다.According to the present invention configured as described above, the controller determines the driver's drowsiness when the distance between the vehicle in front of the driver falls below a certain level at a speed detected by the speed sensor when the driver's vehicle is at a low speed and when the time by the timer is equal to or higher than the predetermined level. Controls to activate the driver's perception through alarms, warning lights and audio.
이하, 예시도면을 참조하면서 본 발명의 실시예를 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 발명의 운전자 졸음 감지장치를 위한 시스템 구성을 나타낸 시스템 구성도이다.1 is a system configuration diagram showing a system configuration for the driver drowsiness detection apparatus of the present invention.
동 도면에 나타낸 바와 같이, 운전자 졸음 감지장치를 운전자 자신이 자신의 상태를 판단하여 감지장치를 온/오프할 수 있도록 온/오프 스위치를 갖추도록 실시한다. 또한, 레이저 센서는 앞차와의 거리를 측정하도록 장치된 것으로 앞차와의 거리를 올바르게 판단하기 위해 자동차의 앞쪽에 장치되도록 실시한다. 또한, 스피드 센서를 갖추어 자동차가 일정 히아의 속도(일정 이상의 시간)를 감지할 수 있도록 하고 일정 이상의 시간을 감지하도록 타이머를 갖추도록 한다.As shown in the figure, the driver's drowsiness detection device is equipped with an on / off switch so that the driver himself / herself can determine his / her state and turn on / off the detection device. In addition, the laser sensor is configured to measure the distance to the front vehicle and is implemented to be mounted to the front of the vehicle to correctly determine the distance to the front vehicle. It is also equipped with a speed sensor that allows the car to detect the speed of a certain period of time (a certain amount of time) and a timer to detect a certain amount of time.
또한, 상기의 레이저 센서, 스피드 센서, 타이머를 통해 감지된 것을 콘트롤 하여 경보음, 경보등의 발생 및 오디오 등에 의해 운전자의 지각을 환기시키도록 하는 콘트롤러를 갖추도록 실시한다.In addition, the controller is configured to control the sensed by the laser sensor, the speed sensor, and the timer so as to vent the driver's perception by generating an alarm sound, an alarm light, and audio.
이상 설명한 바와 같이, 본 발명의 졸음 감지장치는 일반 운전자가 자동차 운행중 교통이 정체되어 저속 운행하게 되면 졸음으로 인해 예기치 못한 사고가 발생될 수 있는 것을 미연에 방지할 수 있도록 한다.As described above, the drowsiness detecting apparatus of the present invention enables the general driver to prevent unexpected accidents due to drowsiness when the vehicle is stopped at low speed due to traffic congestion while driving a vehicle.
