1、家用電風(fēng)扇控制邏輯電路設(shè)計(jì)電子課程設(shè)計(jì)報(bào)告題目名稱：家用電風(fēng)扇控制邏輯電路設(shè)計(jì)姓名：鄒秀蘭專業(yè)：通信工程班級(jí)學(xué)號(hào)：08042104同組人：曾令春指導(dǎo)教師：韋芙芽南昌航空大學(xué)信息工程學(xué)院2010年9月日摘要隨著我國經(jīng)濟(jì)的發(fā)展，居民家中的電器是越來越多，電風(fēng)扇也成為了我們生活中必不可少的家用電器。以前的臺(tái)式電風(fēng)扇和落地式電風(fēng)扇都是采用機(jī)械控制，主要控制風(fēng)速和風(fēng)向。然而隨著電子技術(shù)的發(fā)展，目前的家用電風(fēng)扇大多采用電子控制線路取代了原來的機(jī)械控制器，是電風(fēng)扇的功能更強(qiáng)，操作也更簡便。使電風(fēng)扇的使用變得更為人性化。本次課程設(shè)計(jì)的題目是：家用電風(fēng)扇邏輯控制電路的設(shè)計(jì)。由三個(gè)
2、按鍵分別控制風(fēng)速、風(fēng)種和開關(guān)，并分別用不同顏色的發(fā)光二級(jí)管來顯示風(fēng)扇工作的狀態(tài)。附加按鍵提示音及定時(shí)功能。增加這些都是為了提高電風(fēng)扇的人性化?；倦娐肥抢盟钠珼觸發(fā)器74LS175建立起“風(fēng)速”及“風(fēng)種”狀態(tài)鎖存電路，并由74LS08、74LS1517、4LS175及74LS00構(gòu)成“風(fēng)速”及“風(fēng)種”的循環(huán)。定時(shí)部分由555單穩(wěn)態(tài)脈沖電路及74LS192移位寄存器和74LS48譯碼器構(gòu)成。經(jīng)過一系列的分析、準(zhǔn)備。由于庫房沒有大的板子故將定時(shí)部分焊在另一塊板子上，所以本次課程設(shè)計(jì)除在美觀上有點(diǎn)欠缺外達(dá)到了全部的要求。關(guān)鍵字:電風(fēng)扇、按鍵、脈沖、循環(huán)。目錄前言··

7、家變得強(qiáng)大。而作為二十一世紀(jì)的主義，作為一名大學(xué)生，不僅僅要將理論知識(shí)學(xué)會(huì)，更為重要的是要將所學(xué)的知識(shí)用于實(shí)際生活之中，使理論與實(shí)踐能夠聯(lián)系起來。電子課設(shè)是將理論與實(shí)踐相結(jié)合的一個(gè)非常重要的環(huán)節(jié)，是一個(gè)能真正能提高學(xué)生動(dòng)手與實(shí)踐能力的環(huán)節(jié)。家用電器已經(jīng)變得極為普遍，成了我國家庭中最為普及的家用電器之一。隨著近幾年我國經(jīng)濟(jì)的快速發(fā)展人們的生活水平也逐漸提高了，人們對(duì)家用電器的要求也越來越高。人們希望家用電器能夠?qū)崿F(xiàn)智能化及人性化。而作為人們生活中比不可少的家用電器，電風(fēng)扇的智能化及人性化的設(shè)計(jì)就顯得尤為重要。家用電風(fēng)扇控制邏輯電路設(shè)計(jì)就是針對(duì)這一問題而研究設(shè)計(jì)的。
