摘　　要：近年来,随着我国经济的发展和人们生活水平的提高,拥有私家车的人越来越多,而酒驾导致的交通事故时有发生。为了减少悲剧的发生,设计一种操作简单、功能齐全的酒精测试仪很有必要。基于此,详细分析了酒精测试仪各个模块的功能,并研究了其核心器件。该装置的核心是STC89C52单片机和MQ-3传感器,具有键盘电路、报警电路等相关电路。该系统具备检测、报警、显示等功能,且具有成本低、携带方便、人性化等特点。In recent years, with the development of China’s economy and the improvement of people’s living standards, more and more people own private cars. Traffic accidents caused by drunk driving also occur from time to time, In order to reduce the occurrence of these tragedies, it is necessary to design an alcohol tester with simple operation and complete functions. Based on this, the functions of each module are analyzed in detail, and its core devices are studied. The core of the device is STC89 C52 single chip microcomputer and MQ-3 sensor, and has keyboard circuit, alarm circuit and other related circuits. The system has the functions of detection, alarm and display and has the characteristics of low cost, convenient carrying and humanization.
