Today, the introduction of national law the provisions of the Road Traffic Safety Law, motor vehicle after drinking or drunk driving major traffic accidents, crime is constituted, criminal responsibility shall be investigated by the traffic control department of public security an driving license revoked for life may not regain a driving license. Given people39。s increasing emphasis on the drink driving, alcohol test subject has aroused widespread concern. Drunk driving accidents caused by excessive drinking is caused because the driver39。s alcohol level is too high the body, paralysis of nerves, resulting in slow response to the brain, body out of control and other symptoms. Based research is a kind of gas sensor and microcontrollerbased, monitoring of air alcohol concentration , and with LCD display monitor air alcohol concentration. The need to design an intelligent instruments to monitor the driver39。s alcohol content. This research is a kind of gas sensor and microcontrollerbased, monitoring of air alcohol concentration , and with sound alarm and LCD display monitors the air alcohol concentration. The environment can be monitored from the air and breath alcohol concentration, and according to different environments set different threshold than the threshold of the acoustic alarm, and display threshold. To prompt the hazard. So as to achieve the following purposes: (1) in favor of public transport safety。 (2) to raise awareness of legal consciousness。 (3) to make it convenient, safe, accurate, efficient, easy to increase the popularity of home alcohol test. This work is based on the TGS822 ADC0809 microcontroller sampling to reflect the body alcohol concentration blood alcohol concentration。 and to obtain the temperature DS18B20 Key words: ADC0809。 TGS822。 DS18B20。 MCU 武漢工程大學(xué)郵電與信息工程學(xué)院畢業(yè)設(shè)計(jì)(論文) 1 目 錄 第 1 章 緒論 ......................................................................................................................... 1 精測(cè)試儀現(xiàn)狀和發(fā)展趨勢(shì) ............................................................................ 1 研究?jī)?nèi)容 ........................................................................................................ 2 第 2 章 總體設(shè)計(jì) ................................................................................................................. 3 本課題的設(shè)計(jì)任務(wù)及要求 ............................................................................ 3 設(shè)計(jì)任務(wù) ................................................................................................ 3 設(shè)計(jì)要求 ................................................................................................ 3 系統(tǒng)整機(jī)原理圖分析 .................................................................................... 4 第 3 章 硬件設(shè)計(jì) ................................................................................................................. 5 單片機(jī)模塊 .................................................................................................... 5 ADC0809 資料 ............................................................................................... 7 酒精傳感器模塊 ............................................................................................ 9 傳感器性能分析 ..................................................................................... 9 呼出酒精氣體濃度與血液酒精濃度關(guān)系 ........................................... 12 LCD 模塊 ................................................................................................... 13 第 4 章 系統(tǒng)軟件 ............................................................................................................... 15 整機(jī)系統(tǒng)流程圖 .......................................................................................... 16 程序流程圖 ................................................................................... 16 LCD 程序流程圖 .................................................................................. 17 第 5 章 總結(jié)與展望 ........................................................................................................... 18 參考文獻(xiàn) ............................................................................................................................. 19 致謝 ..................................................................................................................................... 20 附錄 1 酒精測(cè)試儀程序 .................................................................................................... 21 武漢工程大學(xué)郵電與信息工程學(xué)院畢業(yè)設(shè)計(jì)(論文) 1 第 1 章 緒論 精測(cè)試儀現(xiàn)狀和發(fā)展趨勢(shì) 喝酒后,呼 出的氣體會(huì)有酒味,表情行為會(huì)有反常。遠(yuǎn)古時(shí)代人們利用鼻子作為傳感器,進(jìn)行簡(jiǎn)單的呼出氣體酒精測(cè)量。 19 世紀(jì)末出現(xiàn)了用體液對(duì)酒精進(jìn)行定量分析。 1927 年,有科學(xué)家建議使用呼出氣體做酒精濃度分析。用 足球膽收集呼出氣體后,通過(guò)硫酸和重鉻酸鉀的混合溶液,溶液的顏色會(huì)發(fā)生藍(lán)一綠一黃的變化,同已知酒精濃度的標(biāo)準(zhǔn)試劑色管比較,就得到相應(yīng)的 BAC?,F(xiàn)在 , 肺泡氣中酒精的測(cè)量技術(shù)有了很大的進(jìn)步,有先進(jìn)微處理器的酒精測(cè)試儀已被商品化。越來(lái)越多的國(guó)家開(kāi)始禁止酒后駕車。精確的呼出氣體酒精測(cè)試和傳統(tǒng)的法醫(yī)血液酒精分析相比有許多優(yōu)點(diǎn),例
