The invention discloses a vehicle-mounted alcohol detection device and method, and the device comprises an alcohol detection system, a voice recognition judgment system and a physical sign central control system, and is used for detecting whether a driver intakes alcohol or not and the intake level degree, so as to judge whether the driver can drive a vehicle or not. The alcohol detection system disclosed by the invention is used for carrying out preliminary qualitative judgment on whether a driver drinks or not; a voice recognition judgment system is used for further quantitatively judging adriver who is likely to drink; and finally, the sign central control system prompts and controls whether an engine of the vehicle is started or not, so that drunk driving is completely eradicated. According to the invention, the cost is reduced while the complexity of the system is reduced, and meanwhile, the problems caused by regular calibration and regular replacement of the sensor in the existing system are effectively solved.
本发明公开了一种车载酒精检测装置及方法,本发明包括酒精检测系统、语音识别判定系统和体征中控系统,用于检测驾驶员是否摄入酒精及摄入量级程度,以便判断驾驶员是否能够驾驶车辆。本发明的酒精检测系统是用于对驾驶员是否饮酒做一个初步的定性判断;通过语音识别判定系统对可能饮酒的驾驶员做进一步的定量判断;最后通过体征中控系统做出提示并对车辆发动机是否启动进行控制,从而杜绝酒驾醉驾。本发明在降低系统的复杂程度的同时也降低了成本,同时有效的解决了现有系统中传感器定期校准和定期更换带来的问题。
