摘要

设计了一种基于单片机的汽车防酒驾系统。系统以51单片机为核心

由酒精浓度采集调理电路、模/数(A/D)转换电路、按键电路、液晶显示器(LCD)显示电路、报警电路及继电器控制电路等组成。根据防酒驾系统功能需求

编制了系统软件并进行了性能测试。测试结果表明:该系统性能稳定、安全性较高

具有很强的推广应用价值。

Abstract

An anti drunk-driving control system based on micro control unit（MCU） is designed

in order to assure people’s travel safety.The designed system is constructed with alcohol concentration collection and condition circuit

analog/digital（A/D） conversion circuit

button circuit

liquid crystal display（LCD） display circuit

warning circuit

relay control circuit.According to the function requirements of anti-drunk driving system

the system software is compiled and the system performance is tested.The test result shows that the system performance is stable

safety is high and it has high application value.
