【正文】 畢 業(yè) 論 文 ( 設(shè) 計 ) 論文題目 : 基于 89C52 單片機(jī)的 出租車計價器的設(shè)計 學(xué)生姓名 : ****** 學(xué)號: ******* 指導(dǎo)教師: ***** 職稱: 教授 院 系: 物理與電子信息工程學(xué)院 專業(yè)班級: *************************** 二○一二 年 五 月 十 日 基于單片機(jī)的出租車計價器的設(shè)計 2 摘 要 隨著出租車行業(yè)的發(fā)展,出租車已經(jīng)是城市交通的重要組成部分,出租車計價器是乘客與司機(jī)雙方的交易準(zhǔn)則,它是出租車行業(yè)發(fā)展的重要標(biāo)志,是出租車中最重要的工具。它關(guān)系著交易雙方的利益。具有良好性能的計價器無論是對廣大出租車司機(jī)朋友還是乘客來說都是很必要的。因此,汽車計價器的研究也是十分有一個應(yīng)用價值的。而隨著單片機(jī)性能不斷提高而價格不斷下降,單片機(jī)控制在越來越多的領(lǐng)域得以應(yīng)用。本設(shè)計按照傳統(tǒng) 的模式,在整個項目開發(fā)過程中,先根據(jù)控制系統(tǒng)要求設(shè)計原理圖,PCB 電路圖繪制,電路板制作,元器件的焊接,然后進(jìn)行軟件編程,通過仿真器對系統(tǒng)硬件和軟件調(diào)試,最后將調(diào)試成功的程序固化到單片機(jī)中。這一過程中的主要問題是,應(yīng)用程序需要在硬件完成的情況下才能進(jìn)行調(diào)試。本系統(tǒng)是由 89C52 單片機(jī)、數(shù)碼管顯示模塊、計數(shù)脈沖發(fā)生器、及里程計算等模塊組成。 關(guān)鍵字 :單片機(jī) 數(shù)碼管 顯示 計費(fèi) 控制 基于單片機(jī)的出租車計價器的設(shè)計 3 Abstract With the development of the taxi industry, a taxi is an important part of urban transportation, taxi drivers and passengers the message accounting device is both sides of the trading standards, it is an important symbol of development of the taxi trade, is the most important tool in a taxi. It was about trading the interests of both parties. Has good performance both for the message accounting device taxi driver friend or passengers alike is very necessary. Therefore, the research is also very smart meter car has a application value. But along with singlechip microputer with improving performance and prices falling, SCM control in more and more field to the application. This design according to the traditional model, in the whole project development process, according to the control system requirements to design principle diagram, PCB draw circuit diagram, circuit board production, ponents of welding and software programming, through the simulation of the system hardware and software debugging, will ultimately successful program to cure debugging in single chip microputer. This process is the main problem, application needs to finish in the hardware can debugging. This system is made of 89 C52 single chip puter, digital pipe display module, counting pulse generator, and mileage calculation module.
