The invention discloses an intelligent drunk driving prevention method and system based on alcohol concentration detection, and the method comprises the steps: carrying out the partitioning of an environment in a vehicle, judging the seating condition of a driving region in the vehicle through face recognition, and activating an alcohol detection unit in each environment region in the vehicle according to the seating condition; the method comprises the following steps: acquiring the alcohol concentration of each in-vehicle environment area by using spectral analysis through an alcohol detection unit in each in-vehicle environment area, setting an alcohol concentration detection threshold value, and controlling a relay to control the vehicle to be locked when the alcohol concentration of a driving area is greater than the alcohol concentration detection threshold value; and generating voice prompt alarm information for voice broadcast, generating an early warning notification based on the driver personal information, the vehicle basic information and the vehicle position information, and sending the early warning notification according to a preset mode. The device is applied to an automobile, can detect whether the alcohol of a driver exceeds the standard or not to control whether the automobile is allowed to start or not, and has the advantages of drunk driving prevention, detection replacement prevention, misjudgment prevention and high supervision.
本发明公开了一种基于酒精浓度检测的智能防酒驾方法及系统,包括:将车内环境进行分区,通过人脸识别判断车内驾驶区域的落座情况,根据落座情况激活各车内环境区域的酒精检测单元;通过各车内环境区域的酒精检测单元利用光谱分析获取各车内环境区域的酒精浓度,设置酒精浓度检测阈值,当驾驶区域的酒精浓度大于酒精浓度检测阈值时,则控制继电器控制车辆锁定;生成语音提示报警信息进行语音播报,基于驾驶员个人信息、车辆基本信息及车辆位置信息生成预警通知,按照预设方式进行发送。本发明应用于汽车上可以检测驾驶员酒精超标与否来控制汽车是否被允许启动,具有防酒驾,防替检,防误判,高监管的优点。
