【正文】 M. The traffic accident caused by drunk driving most of them. Many countries have bee the first death cause accidents. Now the country has violated the provisions of criminal responsibility of drunk driving. And to investigate the correlation of the human body and equipment used to detect alcohol content problem. Intelligent alcohol concentration detector is mainly used for detecting the concentration of alcohol in the body, can also be used for food processing, wine and other alcohol concentration monitoring need air condition. This design is mainly drunk sperm concentration exceed the standard of testing personnel, detection than the standard and alarm function. Now, gas sensor, lowpower, multifunctional, integrated development, therefore, the alcohol concentration detector has a potential market, for driving under the influence of investigation intelligence alcohol detector, in order to prevent or reduce the occurrence of traffic accidents. At present, check drunk driving, most countries are generally the use of breath alcohol tester detection in to the site, to know is the detection of alcohol content, ensure traffic safety and traffic This article is based on the design of 89C52 single chip microputer as control core, using MQ3 alcohol concentration sensor detection device. The basic idea is: the design of the MQ3 output signal, the system will signal analog to digital conversion, data processing by the MCU, show more than standard, determine the alarm on the LCD, otherwise the Keywords: intelligent alcohol concentration detector, alcohol concentration sensor, singlechip microputer, digital to analog converter, hardware designjLBHrnAILg目錄目錄5xHAQX74J0X引言6LDAYtRyKfE1緒論6Zzz6ZB2Ltk2方案器件簡(jiǎn)介7EmxvxOtOco 單片機(jī)7SixE2yXPq5 STC89C52單片機(jī)100YujCfmUCw4硬件設(shè)計(jì)11sQsAEJkW5T 數(shù)模轉(zhuǎn)換設(shè)計(jì)137EqZcWLZNX LCD1602液晶顯示設(shè)計(jì)151nowfTG4KI5軟件設(shè)計(jì)17tfnNhnE6e5
