1、基于單片機防酒后駕駛控制系統(tǒng)設(shè)計 基于單片機防酒后駕駛控制系統(tǒng)設(shè)計The Design Of Anti-drunk Driving Control System On Single Chip Microcomputer2013 2013 年 6 月ABSTRACTIn recent years, with the popularity of cars in China, safety problem of cars has caused

2、 our attention. According to the latest data, driving after drinking has become the main reason of the car accident, the death that cased by the car accident has been increased at the rate of 7.3%. Driving after drinking

3、 is so dangerous that it cause death or hurt . To avoid the driving after drinking, it is necessary to design a intelligent circuit to check the alcohol concentration and cut off the power of the car in time. The design

4、uses the MQ-3 alcohol sensor to measure the alcohol concentration of the driver's body and send those signals to SCM by A/D0832 converter. In the last, the SCM process the digital signal to display alcohol concentrat

5、ion.When the alcohol concentration beyond the mark of standard alcohol concentration, the system issues a sound light alarm and cuts off the power of the car. In software aspect, every program is independent,so it is eas

6、y when debuging the program. When the driver's alcohol concentration exceeds the safety standard of the system, the design can automatically cut off the power of the car to stop its engine and send out alarm.At the m

7、eantime a digital tube real-time display the alcohol concentration.In this system, this paper chooses AT89C51 SCM, A/D0832 converter, MQ-3Alcohol sensor, Nixie tube, LED, buzzer and relay as it main parts, and through th
