课程设计报告 设计题目: 酒精溶度测试仪 智能酒精浓度检测仪的设计摘 要：随着科技的进步，智能产品在社会生产和人们生活等方面扮演着越来越重要的角色。本文介绍的是一款智能酒精浓度检测仪的设计方案，以STC89C52 单片机和酒精传感器为核心，具有声光报警和 LCD 显示功能。为了满足不同环境下的监测，可根据不同的环境设置不同的阀值，超过阀值即进行声光报警，提示危害。该设计方案的优点是硬件电路设计简单，软件功能采用C 语言进行调试，方便灵活。而该仪器具有灵敏度高、工作性能好、低功耗、低成本，较高的性价比等优点。可用于交通检测、酒厂和食品工厂发酵监控等场所。关键词：智能；酒精浓度；检测仪；STC89C52 单片机；阀值；C 语言；交通检测Design for Intelligent Alcohol Concentration DetectorAbstract: With the progress of science, intelligent products gradually play an important role in many aspects, such as social produce, people’s daily life. This paper introduces an intelligent alcohol concentration detector, which is based on STC89C52 single-chip microcomputer and alcohol sensor (transducer). It has several functions, including detecting alcohol concentration in different environment, giving an alarm with voice and glowing, and LCD display, except for this, we can also set the valve number of alcohol concentration to meet different environment’s detecting, namely, when the detecting num over the value, the detector can suggest danger. The excellences of this design precept : easy hardware circuit ,software function adopt to C language to test, which is convenient and flexible .what’s more, the detector with high delicacy, low energy consumption and spending. It can be used in traffic detect, wine factory, food factory and so on.Key words: intelligent; alcohol concentration; detector; STC89C52 single-chip microcomputer; value ；C language; traffic detect目 录第 1 章绪 论...........................................................
