Description

一种带有驾驶员疲劳检测的手表 Watch with one kind of driver fatigue detecting

技术领域 FIELD

[0001] 本发明涉及一种驾驶员疲劳检测技术,尤其涉及一种用于对驾驶员疲劳状态进行检测的手表式检测装置。 [0001] The present invention relates to a driver fatigue detection technology, and particularly for a watch type detecting means for detecting the fatigue state of the driver.

背景技术 Background technique

[0002] 驾驶疲劳,是指驾驶人在长时间连续行车后,产生生理机能和心理机能的失调,而在客观上出现驾驶技能下降的现象。 [0002] driving fatigue, it refers to the driver after a long period of continuous driving, resulting in physiology and mental function disorders, the emergence of the phenomenon of decline in driving skills objectively. 驾驶人睡眠质量差或不足,长时间驾驶车辆,容易出现疲劳。 The driver of poor quality or inadequate sleep, driving a vehicle for a long time, prone to fatigue. 驾驶疲劳会影响到驾驶人的注意、感觉、知觉、思维、判断、意志、决定和运动等诸方面。 Driving fatigue will affect the driver's attention, feeling, aspects of perception, thinking, judgment, will, decisions and exercise. 疲劳后继续驾驶车辆,会感到困倦瞌睡,四肢无力,注意力不集中,判断能力下降,甚至出现精神恍惚或瞬间记忆消失,出现动作迟误或过早,操作停顿或修正时间不当等不安全因素,极易发生道路交通事故。 After the fatigue continues to drive the vehicle, you will feel sleepy sleepiness, weakness, lack of concentration, decreased ability to judge, even in a trance or instant memories disappear, action or delay premature, improper operation pause or correction time of insecurity appears, road prone to traffic accidents.

[0003] 在现有技术中,对于驾驶员疲劳状态的检测技术主要集中于面部图像识别,即通过安装在车辆内部的几个摄像头来识别驾驶员眼睛的闭合频率、表情等来判断驾驶员是否疲劳。 [0003] In the prior art, the fatigue state of the driver for the detection of the face image recognition focused on, i.e., whether the driver is determined by mounting several cameras to identify the frequency of closing the interior of the vehicle driver's eyes, facial expression, etc. fatigue. 该类技术由于设备复杂、使用不方便等原因,安装使用普及率不高,而且检测出驾驶员处于疲劳状态时仅进行声音提醒,没有主动的车辆控制措施,在驾驶员已经进入疲劳状态时这种声音提醒作用往往收效甚微。 Because of the complexity of such devices Technology, inconvenient to use and other reasons, installation is not a high penetration rate, but only for the detected sound alert a driver in a fatigue state, no active control measures vehicle, the driver has entered the state in which the fatigue voices reminder often with little success.

[0004] 公开日为2011年06月01日、公开号为CN102081832A的中国专利公开了这样的技术方案:一种疲劳驾驶警示仪由一个超生波发射电路,一个超生波接受电路,一个报警延时电路组成,其工作方式是,置疲劳驾驶警示仪于驾驶员下前方位置上,超声波发射头和接受头对准驾驶员面部,当驾驶员处于正常状态时,超声波发射不到驾驶员的面部,因而不报警,当驾驶员因疲劳面部向前低下时,超声波接受头接受到从驾驶员面部返射回来的超声波,经运算放大器放大后,使三极管导通并对电容充电,当电容电压充到2/3电源电压时与非门反转,源蜂鸣器即会发出报警声,以此来提醒驾驶员。 [0004] Publication date is June 1, 2011, Publication No. CN102081832A of Chinese patent discloses a technical solution: A driver fatigue warning device consists of a comeback wave transmitter circuit, a circuit receiving ultrasound waves, an alarm delay circuit, its working mode is set to driver fatigue warning device at the front of the driver position, the first ultrasonic transmitter and receiving head is aligned driver's face, when the driver is in a normal state, the ultrasonic wave emitting surface is less than the driver, thus no alarm, when the driver due to fatigue low forward face, an ultrasonic receiving the driver's face from the first received ultrasonic retroreflective back, amplified by the operational amplifier, so that the transistor is turned on and charges the capacitor when the capacitor voltage charge to inverted NAND gate, source i.e. the alarm will sound the buzzer when the power source voltage 2/3, in order to alert the driver. 该方案的不足之处是:当驾驶员呈现疲劳状态时不一定低下头或睡态,此时就出现漏判,不能起到及时提醒作用,而且同样不具备主动的车辆控制措施。 The shortcomings of the program is: Not necessarily looked down or sleep state when the driver presents fatigue, then appeared Missing, can not play a timely reminder, and does not have the same active vehicle control measures.
