基于单片机的车内酒精自检系统设计
Design of Alcohol Self-checking System in Car Based on Single-Chip Microcomputer
摘要
Abstract
The cause of traffic accidents has been studied,and drunk driving has become one of the main reasons for the high incidence of traffic accidents.The detection of alcohol concentration is an important part of assessing drunk driving.In order to remind drivers to avoid drunk driving,a alcohol self-checking system in car based on Single-Chip Microcomputer is designed.The alcohol concentration in the car is monitored in real time through the MQ-3 alcohol sensor,and the collected analog signal is converted to STC89C52RC Single-Chip Microcomputer by A/D conversion.The processed data are displayed through the LCD display.If the alcohol concentration in the gas exceeds the threshold,the system will send out a sound and light alarm which can attract attention,and at the same time,the circuit controled by relay will brake the car so that the car cannot be started.The system is small in size,easy to carry,and has a certain function of preventing drunk driving to ensure traffic safety.关键词
