Problems solved by technology

[0004] At present, the police can detect the driver's drinking situation by using the air blowing measurement technology, but this can only be a small probability spot check, and it is law enforcement after the event, not prevention in advance, and it cannot really eliminate the occurrence of drunk driving fundamentally

Abstract

The invention discloses an electronic device and a control method for preventing drunken driving. The electronic device comprises a microphone, an alcohol sensor, an alcohol detection module, a first signal amplifier, a second signal amplifier, an analog-digital converter, a counter, an AND gate integrated block and a switch transistor; the microphone is connected with the first signal amplifier which is respectively connected with the analog-digital converter and a starting switch, the analog-digital converter is connected with the counter, and the counter is connected with an input pin of the AND gate integrated block; the alcohol sensor is connected with the second signal amplifier which is connected with the alcohol detection module, and the alcohol detection module is connected another input pin of the AND gate integrated block; the input pin of the AND gate integrated block is connected with a base of the switch transistor, a collector of the switch transistor is respectively connected with the second signal amplifier and an engine ECU (Electronic Control Unit), and an emitter of the switch transistor is connected with a code ECU. The electronic device provided by the invention is capable of preventing drunk driving.

Description

technical field [0001] The invention belongs to the automobile electronic technology, and in particular relates to an electronic device and a control method for preventing drunken driving. Background technique [0002] my country's automobile production is developing rapidly, and the accompanying traffic accidents are also emerging one after another. In the statistics of traffic accidents, traffic accidents caused by drunk driving account for a large proportion. The country has also issued very strict regulations on this, but it has been repeatedly banned. [0003] The harm of drunk driving lies in the result of traffic accidents caused by wrong judgment and uncontrolled hands and feet due to the central nervous system of the driver being affected by alcohol. None of the car's safety features, any advanced mechanical and electronic safety features, can do anything about it. [0004] At present, the police can detect the driver's drinking situation by using the blowing mea...
