1、2013屆畢業(yè)設(shè)計(jì)(論文)題目:基于單片機(jī)的紅外避障小車(chē)學(xué)院:浦江學(xué)院專業(yè):電子信息工程班級(jí):電子0905姓名:徐博指導(dǎo)老師:楊小健起訖日期:2012-12-12~2013-06-102013年06月摘要隨著科學(xué)技術(shù)的進(jìn)步,智能化和自動(dòng)化技術(shù)越來(lái)越普及,各種高科技技術(shù)也廣泛應(yīng)用于智能小車(chē)河機(jī)器人玩具制造領(lǐng)域,使智能機(jī)器人越來(lái)越多樣化。智能小車(chē)是一個(gè)多種高新技術(shù)的集成體,融合了機(jī)械,計(jì)算機(jī)硬件,軟件,電子,人工智能等多種科學(xué)技術(shù)的知識(shí),可以涉及到當(dāng)今許多前言領(lǐng)域的技術(shù)。本設(shè)計(jì)主要由單片機(jī)控制系統(tǒng)模塊、電機(jī)驅(qū)
2、動(dòng)模塊、紅外避障模塊、聲控模塊組成,系統(tǒng)以STC89C52RC單片機(jī)為核心,通過(guò)避障模塊和聲控模塊接受到的信息來(lái)控制電機(jī)運(yùn)行。系統(tǒng)通過(guò)7節(jié)1.5V干電池通過(guò)降壓電路降成5V穩(wěn)定直流電對(duì)單片機(jī)和發(fā)動(dòng)機(jī)進(jìn)行供電。本文介紹了紅外避障的原理、系統(tǒng)整體設(shè)計(jì)及相關(guān)軟件的介紹。軟件部分采用模塊化設(shè)計(jì)思路,整個(gè)程序包括主程序,電機(jī)驅(qū)動(dòng)程序,信號(hào)檢測(cè)程序,通過(guò)小車(chē)運(yùn)行時(shí)檢測(cè)到的運(yùn)行信息來(lái)調(diào)用左轉(zhuǎn)、直行或停止函數(shù)來(lái)控制小車(chē)。測(cè)試結(jié)果表明,本文的各項(xiàng)功能基本正常,除發(fā)動(dòng)機(jī)轉(zhuǎn)速不匹配外能實(shí)現(xiàn)本設(shè)計(jì)的所有要求。關(guān)鍵字:STC89C
