摘　　要：采用STC89C52单片机为核心,选用酒精传感器MQ3设计了一种车载酒精浓度测量仪。系统包括液晶显示模块、数据采集模块、A/D转换模块、超标报警模块、按键设置模块和数据存储模块等。利用MQ3输出电压值与酒精浓度值的线性关系来测量酒精浓度值,并对测量结果进行误差分析。设计的车载酒精浓度测量仪能较好地测量驾驶者体内的酒精浓度值,以便提醒驾驶者遵守交通规则,勿酒驾或醉驾,避免交通事故的发生。Using STC89C52 microcontroller as the core, this paper designs a kind of vehicle alcohol concentration tester. The system includes a liquid crystal display module, data acquisition module, A/I） conversion module, alarm module, exceed the standard key setting module and data storage module. The system has been measuring alcohol concentration value, using a Linear relationship with SensQr MQ3 output voltage value and alcohol concentration value. In this paper, we analyze the error of measurement results. The measuring instrument can measure the driver alcohol concentration data in vivo, in order to remind drivers to comply with traffic rules, do not drink driving or drunk driving, to avoid the occurrence of traffic accidents.
