The invention relates to the technical field of vehicle alcohol detection, and discloses a vehicle alcohol detection self-locking system. The system comprises a blowing control sensor module, an alcohol detection module, a single chip microcomputer, an alarm module, an indication module, a relay, a voltage reduction module and a brake flameout module. According to the invention, a driver needs to carry out expiration operation on the expiration microphone before starting the vehicle, gas enters the gas-sensitive alcohol sensor, at the moment, the single-chip microcomputer sends a trigger signal and starts to detect a gas signal of the gas-sensitive alcohol sensor, the vehicle can be started if the alcohol content does not exceed the standard, otherwise, the single-chip microcomputer sends an instruction to the relay; the ignition device is turned off through the relay, then the single-chip microcomputer gives an instruction, and the emergency contact person pre-stored in advance is contacted through the short message telephone alarm; meanwhile, the GPS positioner sends the position, the position is made to carry out designated driving for the driver, and then the effect that the efficiency of a traditional drunk driving detection method is low is achieved.

    本发明涉及车用酒精检测技术领域,且公开了,一种车用酒精检测自锁系统,包括吹控感应器模块、酒精检测模块、单片机、报警模块、指示模块、继电器、降压模块和制动熄火模块,该车用酒精检测自锁系统,驾驶员在启动车辆前需对呼气话筒进行呼气操作,气体进入气敏酒精传感器内,此时单片机会发送触发信号,开始对气敏酒精传感器的气体信号进行检测,假设酒精含量没有超标,车辆便可以启动,反之,单片机便会向继电器下达指令,通过继电器对点火装置进行关闭随后单片机便会下达指令,通过短信电话报警器联系事先预存的紧急联系人,同时GPS定位器将位置进行发送,让其来为驾驶员进行代驾,进而达到了解决传统检测酒驾方法效率低下的效果。
