1、河北經(jīng)貿(mào)大學(xué)畢業(yè)設(shè)計(jì)(論文)河北經(jīng)貿(mào)大學(xué)畢業(yè)設(shè)計(jì)(論文)基于單片機(jī)的水位控制系統(tǒng)的設(shè)計(jì)系別信息技術(shù)學(xué)院專業(yè)電子信息工程班級(jí)2009(1)班學(xué)生姓名林杰學(xué)號(hào)200907131045指導(dǎo)教師周嚴(yán)良29河北經(jīng)貿(mào)大學(xué)畢業(yè)設(shè)計(jì)(論文)摘要液位測(cè)量廣泛應(yīng)用于工業(yè)、經(jīng)濟(jì)、生活等領(lǐng)域。本設(shè)計(jì)以水箱供水為模型,用于對(duì)水箱液位信號(hào)進(jìn)行測(cè)量監(jiān)控記錄?;趩纹瑱C(jī)的液位測(cè)量裝置具有測(cè)量準(zhǔn)確、重復(fù)性好、功耗低、使用壽命長(zhǎng)的特點(diǎn),是廣泛采用的技術(shù)。在深入學(xué)習(xí)科學(xué)發(fā)展觀的同時(shí),電子設(shè)備的設(shè)計(jì)也需融入可持續(xù)發(fā)展的設(shè)計(jì)理念。故此,在基于單片機(jī)的液位測(cè)量裝置基礎(chǔ)上,擴(kuò)展實(shí)時(shí)監(jiān)控、數(shù)據(jù)采集、計(jì)算機(jī)串行通信等功能,從而
2、能夠通過科學(xué)的方法將液位測(cè)量與統(tǒng)計(jì)科學(xué)結(jié)合,合理調(diào)度水資源,降低能源消耗。本文從系統(tǒng)方案選擇與論證,硬件電路設(shè)計(jì),系統(tǒng)軟件與上位機(jī)軟件設(shè)計(jì)等幾個(gè)方面介紹了基于單片機(jī)的液位測(cè)量監(jiān)控系統(tǒng)的設(shè)計(jì)過程,最終實(shí)現(xiàn)了液位的實(shí)時(shí)測(cè)量與監(jiān)控。最后,本文總結(jié)了設(shè)計(jì)過程中出現(xiàn)的問題及解決方法,簡(jiǎn)要敘述了所獲數(shù)據(jù)的處理方法,引出了進(jìn)一步設(shè)計(jì)開發(fā)的思路。關(guān)鍵詞:?jiǎn)纹瑱C(jī);液位測(cè)量;實(shí)時(shí)監(jiān)控;串口通信29河北經(jīng)貿(mào)大學(xué)畢業(yè)設(shè)計(jì)(論文)TheDesignofLiquidLevelControlSystemBasedonMCUAbstractTheliquidlevelmeasurementiswidelyus
