基于單片機(jī)實(shí)現(xiàn)的顯示搖搖棒的系統(tǒng)設(shè)計(jì)設(shè)計(jì)論文word格式

1、 1 引 言Welcome、漢字詞組“美亞和北京奧運(yùn)會(huì)會(huì)徽?qǐng)D形，并適當(dāng)增加設(shè)計(jì)特色與創(chuàng)新。1.2 系統(tǒng)設(shè)計(jì)思路及特點(diǎn)2 系統(tǒng)理論設(shè)計(jì)2.1 系統(tǒng)總體方案比較及說明圖1 方案一原理框圖該方案線路簡(jiǎn)單，掃描控制開關(guān)可選擇機(jī)械開關(guān)或編碼開關(guān)或水銀開關(guān)，在顯示棒搖擺時(shí)接通線路控制單片機(jī)掃描輸出字符或圖形的列編碼信號(hào)；單片機(jī)外另接有中斷控制按鈕用以切換不同字符或圖形的顯示，LED線陣采用普通三極管驅(qū)動(dòng)，電路采用4節(jié)充電電池供電。此方案的優(yōu)點(diǎn)是：?jiǎn)纹瑱C(jī)C51的端口較多，可實(shí)現(xiàn)顯示數(shù)據(jù)并行傳輸，速度較快，且外圍電路簡(jiǎn)單，調(diào)試較方便。缺點(diǎn)是：為了增大顯示清晰度，除去可能由背景LED燈占用的端口外，單片機(jī)剩余端

2、口無法使線陣中LED燈數(shù)量擴(kuò)展至24只以上；單片機(jī)使用的晶振頻率較大，軟件不易實(shí)現(xiàn)對(duì)計(jì)數(shù)的控制。方案二：由單片機(jī)AT89C2051最小系統(tǒng)、存放器組、驅(qū)動(dòng)電路、LED線陣和電源局部組成，原理方框圖如圖2所示。圖2 方案二系統(tǒng)設(shè)計(jì)框圖2.2 系統(tǒng)總體結(jié)構(gòu)設(shè)計(jì)及說明 圖 系統(tǒng)總體結(jié)構(gòu)框圖2.系統(tǒng)硬件理論設(shè)計(jì)、電路原理圖 圖4 單片機(jī)最小系統(tǒng) 存放器組電路存放器組電路如圖5所示，存放器組由三個(gè)八位移位存放器74HC164組成，時(shí)鐘觸發(fā)信號(hào)同時(shí)來自單片機(jī)P3.1口，存放器U3輸入端接入來自P3.0口的串行輸出信號(hào)，其余兩存放器輸入端接在左邊存放器的輸出端上，組成的存放器組具有24位移位功能，可以滿足按

3、列至少16只LED燈掃描顯示的要求。圖5 存放器組電路 掃描控制開關(guān)該開關(guān)接線原理圖如圖6a所示，掃描控制開關(guān)起著擺動(dòng)傳感作用，每當(dāng)顯示棒擺動(dòng)至左端位置時(shí)，開關(guān)瞬時(shí)接通，中斷信號(hào)送入單片機(jī)，控制假設(shè)干次掃描信號(hào)輸出。方案一：采用機(jī)械式開關(guān)，如圖6b所示，紅色弧線代表擺子的導(dǎo)軌，限制其擺動(dòng)軌道，P1和P2為左右觸點(diǎn)，P1接至中斷口INTO，P0接地，該開關(guān)材料和制作簡(jiǎn)單，但擺子轉(zhuǎn)軸和地線接觸可靠性較差。a b 機(jī)械開關(guān)圖6 掃描控制開關(guān)方案二：采用光限位開關(guān)，可靠性很強(qiáng)，但擺棒的粗細(xì)需匹配，開關(guān)體積過大，而且難以購置，價(jià)格昂貴。方案三：采用水銀開關(guān)，其體積較小，價(jià)格適中，可靠性強(qiáng)，選擇此方案。

4、自動(dòng)掉電控制電路自動(dòng)掉電控制電路原理如圖7所示， 其中按鍵S作為電源開關(guān)和顯示切換開關(guān)，按下此鍵時(shí)，PNP型三極管進(jìn)入飽和導(dǎo)通狀態(tài)，接通單片機(jī)電源，此時(shí)由程序控制單片機(jī)持續(xù)送入低電平信號(hào)，使三極管保持導(dǎo)通狀態(tài)；假設(shè)一段時(shí)間內(nèi)掃描控制開關(guān)和顯示切換開關(guān)均未送入中斷信號(hào)，那么單片機(jī)送出高電平，三極管截止，系統(tǒng)進(jìn)入休眠省電狀態(tài)；未進(jìn)入省電狀態(tài)時(shí)再次按下開關(guān)S，單片機(jī)產(chǎn)生中斷，變換顯示的字符或圖形。圖7 自動(dòng)掉電控制電路 LED驅(qū)動(dòng)及顯示電路 LED驅(qū)動(dòng)及顯示電路如圖8所示，LED燈點(diǎn)亮所需電流一般為三至五毫安，八只LED總電流只有幾十毫安，因此驅(qū)動(dòng)采用一只普通三極管即可，圖中二極管D1D3起分壓作用

5、，所有LED點(diǎn)亮的控制信號(hào)來自三個(gè)存放器74HC164。 圖8 LED驅(qū)動(dòng)及顯示電路 系統(tǒng)總圖： 2.4系統(tǒng)軟件設(shè)計(jì)、各程序流程圖a所示，需實(shí)現(xiàn)的功能是初始化各端口和變量。判斷圖文切換按鍵和中斷開關(guān)是否被按下，假設(shè)沒按下，那么延時(shí)假設(shè)干秒后進(jìn)入休眠省電模式；假設(shè)按下，那么進(jìn)行字符的切換顯示。2按鍵中斷實(shí)現(xiàn)數(shù)據(jù)掃描切換程序流程圖如圖9 b 所示，單片機(jī)外部中斷源有2個(gè)，采用外部中斷0作為判斷是否搖擺的端口，該端口連接水銀開關(guān)，如果有搖擺，那么觸發(fā)外部中斷，進(jìn)行掃描數(shù)據(jù)處理。3賦值子程序流程圖如圖10 a 所示，賦值前先檢測(cè)中斷是否有效，如有效,那么將要顯示的字符數(shù)據(jù)依次送入存放器，送完后返回。否

6、那么返回到中斷入口處等待下一次中斷的到來。4定時(shí)間隔子程序流程圖如圖10 b 所示，首先判斷掃描間隔是否太大，如果太大，那么使用默認(rèn)間隔，否那么啟動(dòng)定時(shí)器，在定時(shí)期間判斷中斷是否又被觸發(fā)，如果有，那么定時(shí)停止，強(qiáng)行返回。否那么等到定時(shí)結(jié)束后再返回到掃描子程序中。圖10 程序流程圖23 系統(tǒng)實(shí)現(xiàn)3.1硬、軟件分別調(diào)試及聯(lián)合調(diào)試階段調(diào)試 聯(lián)合調(diào)試 3.2 方案的修改、說明4 系統(tǒng)測(cè)試4.1實(shí)驗(yàn)、測(cè)試儀器與測(cè)試試驗(yàn)方法型號(hào)指標(biāo)生產(chǎn)廠家數(shù)量雙蹤示波器SS-7802A20Hz日本巖崎1 穩(wěn)壓電源WD-5+5V， -5V,-啟東市斯邁計(jì)算機(jī)廠Vc9806+位深圳市勝高電子科技公司14.2 測(cè)試數(shù)據(jù)及測(cè)試結(jié)
