Abstract

The invention provides a drunk driving preventing instrument and belongs to the technical field of sensor detection. The drunk driving preventing instrument is mainly composed of an alcohol sensor, ahuman body infrared induction module, a single-chip microcomputer, an LCD display module, a sound and light alarm module and an ignition circuit. The drunk driving preventing instrument is characterized in that the alcohol sensor and the human body infrared induction module are arranged at the input end of the single-chip microcomputer, the LCD display module is arranged at the output end of the single-chip microcomputer, and the sound and light alarm module and the ignition circuit are arranged at the output end of the single-chip microcomputer. According to the drunk driving preventing instrument, the adopted sensor is high in sensitivity and monitors the alcohol concentration in air in a vehicle in real time, a driver can be reminded, the ignition circuit can be cut off automatically when a measured value surpasses a preset value, drunk driving can be effectively prevented, and damage to personal property by accidents is reduced.

Description

technical field [0001] The invention relates to an anti-drinking driving instrument, which belongs to the technical field of sensor detection. Background technique [0002] Since the 21st century, with the rapid development of science and technology, people's living standards have been continuously improved, and per capita income has increased steadily. Cars have been integrated into every family and become people's daily assistants. Traveling by car saves us precious time, thereby improving the efficiency of work, but another serious problem also arises thereupon, and traffic accidents caused by drunk driving occur frequently. For this reason, our country includes drunk driving within the scope of criminal law. So it is very necessary to design an intelligent instrument that can detect the alcohol content in the driver's car and automatically control the engine. Contents of the invention [0003] Aiming at the above-mentioned deficiencies, the invention provides an anti...
