1、本科畢業(yè)設(shè)計(jì)(論文)基于單片機(jī)的超聲波車用鋼板測厚系統(tǒng)設(shè)計(jì)學(xué)院名稱:汽車與交通工程學(xué)院專業(yè):汽車服務(wù)工程班級:13汽車卓越學(xué)號:姓名:侯沖指導(dǎo)教師姓名:李麗指導(dǎo)教師職稱:講師二〇一七年六月江蘇理工學(xué)院畢業(yè)設(shè)計(jì)說明書(論文)基于單片機(jī)的超聲波車用鋼板測厚系統(tǒng)設(shè)計(jì)摘要:汽車鋼板在汽車長期運(yùn)行的過程中會因各種原因發(fā)生銹蝕,嚴(yán)重的銹蝕會引起鋼板斷裂,進(jìn)而對行車安全造成極大隱患,因此對汽車鋼板厚度進(jìn)行定期測量十分必要。此外,在汽車的生產(chǎn)過程中,同樣要對其鋼板厚度進(jìn)行測量,由此來檢測所用的鋼板是否符合要求。
2、本課題在對比了目前用于厚度檢測的多種方法的基礎(chǔ)上,選擇了基于單片機(jī)的超聲波車用鋼板測厚系統(tǒng)進(jìn)行了重點(diǎn)研究。所設(shè)計(jì)的測厚系統(tǒng)采用超聲波脈沖回波法對鋼板厚度進(jìn)行測量,具有結(jié)構(gòu)簡單、操作方便等優(yōu)點(diǎn)。測厚系統(tǒng)的硬件與軟件設(shè)計(jì)是本課題的重點(diǎn)。其中硬件設(shè)計(jì)部分包括STC89C52模塊、超聲波發(fā)射與接收模塊、獨(dú)立按鍵模塊、溫度補(bǔ)償模塊和電源模塊。軟件設(shè)計(jì)部分采用C語言編寫軟件程序,程序包括主程序部分、計(jì)數(shù)器部分、鍵盤部分和溫度補(bǔ)償部分。關(guān)鍵詞:超聲波;單片機(jī);測厚DesignofanUltrasonicAut
