本科生毕业设计(论文) 基于单片机的汽车尾气检测系统的设计 The design of automobile exhaust detection system based on single chip microcomputer 学士学位论文原创性声明 本人郑重声明:所呈交的设计(论文)是本人在指导老师的指导下独立进行研究,所取得的研究成果,除了文中特别加以标注引用的内容外,本设计(论文)不包含任何其他个人或集体已经发表或撰写的成果作品。对本文的研究作出重要贡献的个人和集体,均已在文中以明确方式表明。本学位论文原创性声明的法律责任由本人承担。 学位论文作者签名(手签): 年 月 日 摘 要 当前汽车尾气排放是导致空气污染的主要因素之一,汽车尾气中未燃尽的CO等氧化物以及可以对人体产生致病影响的固体颗粒物,对人体危害最大。由于近些年我国汽车持有量增速迅猛,人们对汽车的维护工作达不到一定的要求,定期检查也不严格规范,对此,研究简易便携式汽车尾汽检测装置,无论是从约束车主加大自身对汽车保养的力度方面还是从加大监测部门的执行力度上都是有益而无害的。 设计分为主控制端和报警端两部分,其中负责信号采集的主控制端使用专用传感器对汽车尾气中的CO和PM2.5的浓度进行检测,当有害气体排放超过设定上限时,STC12C5A60S2型单片机控制无线发射模块给报警端信号,系统产生报警。同时汽车的排放物信息在液晶显示屏上能够进行实时地显示,主控端还可以对报警阈值进行合理的设定。不论是从当前的行业现状以及对未来的推广和发展,本设计都具有一定的研究意义。 关键词:单片机;汽车尾气;检测;报警 ABSTRACT The automotive exhaust emissions, which contribute to one of the main factors of air pollution, automobile exhaust does not burn the CO oxide and pathogenic effect of solid particles on the human body, the greatest harm to the human body. Because in recent years, Chinas Automobile Holdings rapid growth, people on the cars maintenance work is not up to the requirements, regularly check is not strictly regulate. In this regard, the simple and portable automobile tail gas detection device, whether it is from the constraint owners increase their competitiveness on the vehicle maintenance of or from increase efforts to implement the monitoring department are harmless and beneficial. Design is divided into a main control terminal and alarm terminal, which is responsible for signal acquisition of the master control terminal using special sensor for automobile exhaust CO and PM2.5 concentrations were detected, when the harmful gas emissions exceed a set upper limit, STC12C5A60S2 MCU control wireless transmission module block to the alarm signal terminal, the system will generate a warning. At the same time, the vehicle emission information can be displayed in real time in LCD, and the main con
