【正文】 s first disaster, while China is the world39。s largest traffic accident death toll of the country. 2018, 3906164 of countrywide traffic accident, resulting in 65225 deaths, 254075 people were injured, 930000000 yuan of direct property loss (news source: . COM. 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
