1、汽車倒車防撞系統(tǒng)汽車倒車?yán)走_(dá)論文-40-汽車倒車防撞系統(tǒng)汽車倒車防撞系統(tǒng)摘要隨著社會經(jīng)濟(jì)的發(fā)展交通運(yùn)輸業(yè)日益興旺，汽車的數(shù)量在大副攀升。交通擁擠狀況也日趨嚴(yán)重，撞車事件屢屢發(fā)生，造成了不可避免的人身傷亡和經(jīng)濟(jì)損失，針對這種情況，設(shè)計(jì)一種響應(yīng)快，可靠性高且較為經(jīng)濟(jì)的汽車防撞預(yù)警系統(tǒng)勢在必行，超聲波測距法是最常見的一種距離測距方法，本文介紹的就是利用超聲波測距法設(shè)計(jì)的一種倒車防撞報(bào)警系統(tǒng)。論文的內(nèi)容是基于STC89C52單片機(jī)倒車防撞系統(tǒng)的設(shè)計(jì)，主要是利用超聲波的特點(diǎn)和優(yōu)勢，將超聲波測距系統(tǒng)和STC89C52單片機(jī)結(jié)合于一體，設(shè)計(jì)出一種基

2、于STC89C52單片機(jī)的倒車防撞報(bào)警系統(tǒng)。該系統(tǒng)采用軟、硬件結(jié)合的方法，具有模塊化和多用化的特點(diǎn)。論文概述了超聲波檢測的發(fā)展及基本原理，闡述了超聲波傳感器的原理及特性。對于系統(tǒng)的一些主要參數(shù)進(jìn)行了討論，并且在介紹超聲波測距系統(tǒng)功能的基礎(chǔ)上，提出了系統(tǒng)的總體構(gòu)成。通過多種發(fā)射接收電路設(shè)計(jì)方案比較，得出了最佳設(shè)計(jì)方案，并對系統(tǒng)各個設(shè)計(jì)單元的原理進(jìn)行了介紹。對組成各系統(tǒng)電路的芯片進(jìn)行了介紹，并闡述了它們的工作原理。論文介紹了系統(tǒng)的軟件結(jié)構(gòu)，通過編程來實(shí)現(xiàn)系統(tǒng)功能。最后，通過對系統(tǒng)的誤差分析，給出了系統(tǒng)的改進(jìn)方案。關(guān)鍵字單片機(jī)/超聲波/ST
