Abstract

The invention discloses an automobile unlocking device for automatically detecting alcohol. The automobile unlocking device is characterized by comprising an AT89S51 single chip microprocessor, and an operating keyboard, an alcohol sensor, a buzzer alarm, a display device and a drive device, which are respectively connected with the AT89S51 single chip microprocessor, the automobile unlocking device is suitable for car owners to use, before a car is started by a driver, the alcohol concentration can be initiatively detected, when the alcohol concentration is out of limit, the buzzer alarm can issue an alarm sound to remind the driver of the out-of-limit alcohol concentration, an LCD display screen displays the current alcohol concentration and suggests a rest time, the driver can take corresponding means according to the prompting, and safety, convenience and practicability can be realized; when the alcohol concentration is out of limit, even when the driver rotates a key, the car cannot be successfully ignited, only when the alcohol content falls in the specified range, the ignition device can be switched on, the car can be started, the drunk driver can be prevented from driving the car, the traffic accident occurrence rate can be reduced, and the development prospect is greatly promising.

Description

technical field [0001] The invention relates to the technical field of drunk driving detection, in particular to a car unlocking device for automatic detection of alcohol and an implementation method thereof. Background technique [0002] Drunk driving is the number one killer of traffic accidents, and it is extremely harmful. About 50% to 60% of traffic accidents are related to drunk driving. In China, there are tens of thousands of traffic accidents caused by drunk driving every year.
