The gradual strengthening of the human awareness of environmental protection, it is more concerned about the fuel consumption of the vehicle, to restrict the fuel consumption of the vehicle is more urgent. Therefore, the study of the car39。s average fuel consumption, instantaneous fuel consumption, speed and mileage.The system was developed to provide a new direction will be the development of accurate detection of vehicle fuel consumption, to create a new platform for China39。 sensor。 speed。 intelligent detection 桂林電子科技大學(xué)畢業(yè)設(shè)計(jì)(論文)報(bào)告用紙目 錄引言 ...........................................................11 緒論 ........................................................21.1 國(guó)內(nèi)外汽車(chē)油耗智能檢測(cè)技術(shù)的研究背景 .................................2 國(guó)內(nèi)背景............................................................................................................................2 國(guó)外背景............................................................................................................................31.2 研究水平與發(fā)展趨勢(shì).......................................................................................................32 汽車(chē)油耗智能檢測(cè)技術(shù)研究的意義及內(nèi)容 ........................42.1 汽車(chē)油耗檢測(cè)技術(shù)研究的意義 ...........................................42.2 本文的主要研究?jī)?nèi)容 ...................................................42.3 系統(tǒng)的功能要求 .......................................................42.4 總體設(shè)計(jì)思路 .........................................................53 硬件電路設(shè)計(jì) ................................................63.1 單片機(jī)的選擇 .........................................................63.2 AT89S52 單片機(jī)的介紹 ..................................................................................................63.3 顯示模塊.........................................................................................................................123.4 電源轉(zhuǎn)換模塊.................................................................................................................123.5 傳感器模塊 ..........................................................133.6 單片機(jī)斷電檢測(cè)模塊.....................................................................................................173.7 數(shù)據(jù)保存芯片 24C02....................................................................................................183.8 按鍵模塊.........................................................................................................................193.9 本章小結(jié).........................................................................................................................204 軟件的設(shè)計(jì)與調(diào)試 ...................................................214.1 初始化程序.....................................................................................................................214.2 測(cè)量油耗邏輯程序設(shè)計(jì)..................................................................................................224.3 LCD 顯示程序 .........................................................244.4 本章小結(jié) ............................................................255 系統(tǒng)制作及調(diào)試 .............................................265.1 板子的制作...........................................................26 Protel99 的使用步驟及經(jīng)驗(yàn) ...........................................................................................26 電路板的制作步驟..........................................................................................................275.2 系統(tǒng)的軟硬件調(diào)試.....................................................28 系統(tǒng)調(diào)試使用的儀器.....................................................................................................28 系統(tǒng)調(diào)試的內(nèi)容..............................................................................................................28 桂林電子科技大學(xué)畢業(yè)設(shè)計(jì)(論文)報(bào)告用紙 系統(tǒng)調(diào)試過(guò)程中遇到的問(wèn)題.........................................................................................28結(jié) 論 ........................................................29謝 辭 ........................................................30參考文獻(xiàn) ......................................................31附 錄 ........................................................32原理圖 ...................................................................32PCB 圖....................................................................33程序 .....................................................................35 桂林電子科技大學(xué)畢業(yè)設(shè)計(jì)(論文)報(bào)告用紙 第 1 頁(yè) 共 50 頁(yè)引言汽車(chē)的油耗檢測(cè)是衡量汽車(chē)燃料經(jīng)濟(jì)性及汽車(chē)發(fā)動(dòng)機(jī)性能的重要手段,它通過(guò)測(cè)
