毕业论文-酒精测试仪酒后驾车控制器.doc

PAGE\*MERGEFORMATIII摘要酒后驾车造成交通事故不计其数，带来很大危害。各国都在采取各种方法来解决这个问题，但最终没有找到一个很好的解决方法。酒后驾车控制器就是因此而设计的。在这之前，同类产品国内外已有，但都因为成本、可靠性、方便性等原因没有得到推广。本设计就是在前人基础上，使其有效、可靠的控制酒后驾车，并将完善其他功能。最终目的是使它能够得到广泛应用，最大限度的限制和杜绝酒后驾车现象。设计采用半导体酒精探头，其特点是灵敏度高、稳定、可靠；控制器采用89C2051单片机，其具有体积小、功耗低和带有电位比较器；设计上采用发射和接收分离的无线传输技术，使其设备体积小、使用方便、易操作、易安装等特点。此外发射端发送信息码，接收端检验接收码正确性，从而增加了电子锁的功能；整体来说，该设计有成本低、结构简单、可靠性强、易于使用的特点，将会成为汽车上不可或缺的安全工具。关键词：酒后驾车控制器；酒精探头；89C2051；无线传输技术；信息码；电子锁AbstractCausingthetrafficaccidenttobecountlessbycarafterdrinking,bringandendangergreatly.Variouscountriesaretakingvariouskindsofmethodstosolvethisproblem.Buthasnotfoundaverygoodsolutionfinally.Thecontrolleriswhatisdesignedbecauseofthistodriveafterdrinking.Beforethis,therearethelikeproductshavebothathomeandabroad,butbecauseofthecost,dependability,thereasonofhelpingetc.isnotpopularized.Itistomakeitseffective,reliablecontroldriveafterdrinkingonthebasisofforefatherstooriginallydesign,andwillperfectotherfunctions.Thefinalpurposeistomakeitusedwidely,maximumrestrictionandphenomenonofstoppingtodriveafterdrinking.Designingandadoptingthesemiconductoralcoholsensor,itscharacteristicisthatsensitivityishigh,andsteady,reliable;Thecontrolleradopts89C2051one-chipcomputer,ithassmall,lowpowerdissipationandhavingelectricpotentialcomparators;Adoptlaunchingandreceivethewirelesstransmissiontechnologyseparatedonthedesign,makeitsequipmentsmall,easytouse,easytoinstall,inadditionlaunchtheendtosendtheinformationyard,receivetheendtoexamineandreceiveoneyardofexactness,thusthefunctionincreasingelectronlocking;Comewhollytosay,thisdesigniswithlowcostsofsimplestructure,willbecomeatoolwhichindispensableontheautomobilewith.Keywords:Drivethecontrollerafterdrinking;alcoholsensor;89C2051;wirelesstransmissiontechnology;informationyard;theelectronlocking目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc295459246"摘要PAGEREF_Toc295459246\hIHYPERLINK\l"_Toc295459247"AbstractPAGEREF_Toc295459247\hIIHYPERLINK\l"_Toc295459248"第1章绪论PAGEREF_Toc295459248\h3HYPERLINK\l"_Toc295459249"1.
