Abstract
Description
本發明係與行車安全有關;特別是指一種疲勞駕駛警示裝置及疲勞駕駛警示方法。 The invention relates to driving safety; in particular to a fatigue driving warning device and a fatigue driving warning method.
駕駛對自身的疲勞程度容易缺乏自覺,常有錯估體力而逞強上路,或因長途駕駛久坐致精神不濟,注意力無法集中而導致交通事故發生之情事。由於疲勞駕駛往往無法憑藉駕駛的個人意志避免,故相較於酒後駕車,反而是更難以預防的道路危安因素;因此,如何在行車中判斷駕駛的疲勞度,遂成為維護用路安全的一大課題。 Driving is less likely to be self-conscious, and often has a wrong estimate of physical strength and barely on the road, or because of long-distance driving for a long time, the spirit is not good enough, and the attention can not be concentrated, resulting in traffic accidents. Because fatigue driving can't be avoided by the personal will of driving, it is more difficult to prevent road safety factors than drunk driving; therefore, how to judge the fatigue of driving in driving, it becomes safe for maintenance. A big topic.
現今已有多種判斷駕駛疲勞度的概念性方法,如藉由駕駛的眨眼頻率或臉部表情變化(如呵欠連連)判斷其疲勞度等等,惟該些外顯的「身體語言」之準確度並不如身體內部的生理特徵變化,而血氧濃度可用以做為疲勞度依據之事實素為醫界所知,但現有的血氧機多採用指夾式設計,需要將血氧機夾在手指頭上以偵測血氧濃度,這樣的偵測方式將使得駕駛綁手綁腳,並不適於操控車輛之時。 There are a number of conceptual methods for judging driving fatigue, such as the blinking frequency of driving or facial expression changes (such as yawning) to determine their fatigue, etc., but the accuracy of these explicit "body language" It is not as good as the physiological characteristics of the body, and the fact that the blood oxygen concentration can be used as the basis for fatigue is known to the medical community. However, the existing oximeters are mostly finger-clip design, and the oximeter needs to be clamped to the fingers. The head is used to detect the blood oxygen concentration. This kind of detection will make the driver tie the foot and is not suitable for the vehicle.
有鑑於此,本發明之目的用於提供一種疲勞駕駛警示裝置及疲勞駕駛警示方法,能透過偵測駕駛的血氧濃度以判斷其疲勞度,且不會影響到駕駛對車輛的一般操作,還能更進一步提振駕駛的精神。 In view of the above, the object of the present invention is to provide a fatigue driving warning device and a fatigue driving warning method capable of determining the fatigue degree by detecting the blood oxygen concentration of the driving without affecting the general operation of the driving to the vehicle. Can further boost the spirit of driving.
緣以達成上述目的,本發明所提供之疲勞駕駛警示裝置包括有一血氧機、一訊息收送單元與一音訊播放單元;該血氧機係配戴於一駕駛身上,且具有一感測單元,該感測單元用於量測該駕駛耳垂部位的血氧濃度,並於該駕駛的血氧濃度低於一門檻值時送出一警示訊息;該訊息收送單元用以接收該血氧機之該感測單元所送出的警示訊息,並於接收到該警示訊息後送出一啟動訊息;該音訊播放單元用以接收該訊息收送單元所送出的啟動訊息,並於接收到該啟動訊息後播放一音訊。 In order to achieve the above object, the fatigue driving warning device provided by the present invention comprises an oximeter, a message receiving unit and an audio playing unit; the oximeter is worn on a driving body and has a sensing unit. The sensing unit is configured to measure a blood oxygen concentration of the driving earlobe portion, and send a warning message when the blood oxygen concentration of the driving is lower than a threshold value; the message receiving unit is configured to receive the blood oxygen machine The warning message sent by the sensing unit sends a start message after receiving the warning message; the audio playback unit is configured to receive the start message sent by the message receiving unit, and play after receiving the start message An audio message.
本發明所提供之疲勞駕駛警示方法包含下列步驟:量測一駕駛耳垂部位的血氧濃度;若量測到的血氧濃度低於一門檻值,送出一警示訊息;接收該警示訊息並轉換為一啟動訊息以控制播出一音訊。 The fatigue driving warning method provided by the present invention comprises the steps of: measuring a blood oxygen concentration of a driving earlobe portion; and sending a warning message if the measured blood oxygen concentration is lower than a threshold value; receiving the warning message and converting into A start message is used to control the broadcast of an audio message.
藉此,本發明所提供之疲勞駕駛警示裝置及疲勞駕駛警示方法能夠在不影響駕駛對車輛操作的前提下量測疲勞度,並能進一步提振其精神。 Thereby, the fatigue driving warning device and the fatigue driving warning method provided by the present invention can measure the fatigue degree without affecting the operation of the vehicle, and can further enhance the spirit.
