本設(shè)計(jì)采用內(nèi)部時(shí)鐘方式的電路。AT89C51單片機(jī)內(nèi)部有一個(gè)用于構(gòu)成振蕩器的高增益反相放大器,該高增益反相放大器的輸入端為芯片引腳XTAL1,輸出端為引腳XTAL2。這兩個(gè)引腳跨接石英晶體振蕩器和微調(diào)電容,就構(gòu)成了一個(gè)穩(wěn)定的自激振蕩器。電路中的電容C1和C2典型值通常選擇為33pF左右。晶體的振蕩頻率的范圍通常是在1.2MHZ～12MHZ之間。晶體的頻率越高,則系統(tǒng)的時(shí)鐘頻率也就越高,單片機(jī)的運(yùn)行速度也就越快。.圖3-3時(shí)鐘電路3.3復(fù)位電路 復(fù)位電路通常采用上電自動(dòng)復(fù)位和按鈕復(fù)位兩種方式。本次設(shè)計(jì)采用上電復(fù)位電路。上電復(fù)位電路是在上電瞬間來(lái)實(shí)現(xiàn)的,其電路如圖3-4所示。上電時(shí),RESET端維持兩個(gè)機(jī)器周期的高電平實(shí)現(xiàn)復(fù)位。圖3-4復(fù)位電路3.4PG160128A顯示電路PG160128A是一種圖形點(diǎn)陣液晶顯示器,它主要由行驅(qū)動(dòng)器/列驅(qū)動(dòng)器及格160×128全點(diǎn)陣液晶顯示器組成?？赏瓿蓤D形顯示,也可以顯示10×8個(gè)<16×16點(diǎn)陣>漢字。主要技術(shù)參數(shù)和性能：模塊內(nèi)自帶-15負(fù)壓,用于LCD的驅(qū)動(dòng)電壓電源VDD：+5V；2.顯示內(nèi)容：160<列>×128<行>點(diǎn)3.全屏幕點(diǎn)陣4.十三種指令5.與CPU接口采用8位數(shù)據(jù)總線并行輸入輸出6.占空比1/1287.工作溫度：-10℃∽+55℃,存儲(chǔ)溫度：-20℃∽+70℃這里通過(guò)PG160128A來(lái)顯示相關(guān)信息圖3-5顯示電路ADC0832是美國(guó)國(guó)家半導(dǎo)體公司生產(chǎn)的一種8位分辨率、雙通道A/D轉(zhuǎn)換芯片。學(xué)習(xí)并使用ADC0832可是使我們了解A/D轉(zhuǎn)換器的原理,有助于我們單片機(jī)技術(shù)水平的提高。這里通過(guò)ADC0832將壓力傳感器輸出的電壓信號(hào)轉(zhuǎn)換為數(shù)字信號(hào),并送入到單片機(jī)中進(jìn)行處理。3.5A/D轉(zhuǎn)換電路4系統(tǒng)軟件設(shè)計(jì)4.1主程序框圖開(kāi)始開(kāi)始<1>主程序流程框圖如下:<2>信號(hào)采集子程序框圖如下：開(kāi)始開(kāi)始置數(shù)據(jù)區(qū)首地址信號(hào)采集置數(shù)據(jù)區(qū)首地址信號(hào)采集設(shè)置采集個(gè)數(shù)求出壓力值設(shè)置采集個(gè)數(shù)求出壓力值A(chǔ)/D轉(zhuǎn)換開(kāi)始LCD顯示數(shù)值A(chǔ)/D轉(zhuǎn)換開(kāi)始LCD顯示數(shù)值等待轉(zhuǎn)換結(jié)束等待轉(zhuǎn)換結(jié)束儲(chǔ)存,轉(zhuǎn)換中斷開(kāi)始設(shè)置數(shù)據(jù)存儲(chǔ)區(qū)首址設(shè)置采集數(shù)據(jù)個(gè)數(shù)儲(chǔ)存,轉(zhuǎn)換中斷開(kāi)始設(shè)置數(shù)據(jù)存儲(chǔ)區(qū)首址設(shè)置采集數(shù)據(jù)個(gè)數(shù)對(duì)數(shù)據(jù)進(jìn)行處理恢復(fù)現(xiàn)場(chǎng)返回圖4-3數(shù)字濾波流程框圖波流程框圖4.2顯示子程序框開(kāi)始開(kāi)始初始化調(diào)用顯示函數(shù)返回圖4-4顯示子程序流程圖5系統(tǒng)調(diào)試過(guò)程通過(guò)上面的設(shè)計(jì),設(shè)計(jì)已經(jīng)基本完成。下面主要實(shí)現(xiàn)AltiumDesigner的原理圖、印制板圖的繪制和做相關(guān)檢測(cè),對(duì)Keil進(jìn)行相應(yīng)的檢查和調(diào)試,并用Proteus對(duì)所設(shè)計(jì)系統(tǒng)進(jìn)行仿真。5.1原理圖和印制板圖繪制和檢查5.1.1在protel99se繪制原理圖并進(jìn)行相應(yīng)的ERC檢查圖5-1原理圖的繪制繪制完原理圖之后,對(duì)原理圖進(jìn)行編譯檢測(cè),ERC檢測(cè)結(jié)果。5.1.2在PROTEL99SE生成PCB圖在創(chuàng)建完原理圖后,對(duì)各元器件的引腳進(jìn)行封裝,在原理圖中創(chuàng)建網(wǎng)絡(luò)表<NET>,然后再PROTEL99S中新建PCB,對(duì)于生成的PCB圖中各器件進(jìn)行調(diào)整,并布線,最終生圖5-2生成PCB圖5.2Keil程序調(diào)試程序調(diào)試結(jié)果如下所示：creatinghexfilefrom"壓力檢測(cè)系統(tǒng)"..."壓力檢測(cè)系統(tǒng)"-0Error<s>,0Warning<s>.5.3Proteus仿真調(diào)試在Proteus中建立仿真圖。按下開(kāi)始仿真按鈕,開(kāi)始進(jìn)行仿真實(shí)驗(yàn),結(jié)果如圖5-4,圖5-5,圖5-6所示：圖5-4Proteus仿真圖圖5-5Proteus仿真圖圖5-6Proteus仿真圖仿真電路圖中實(shí)現(xiàn)對(duì)壓力檢測(cè)的控制,輸出到PG160128A顯示。結(jié)論通過(guò)MPX4250檢測(cè)到壓力信號(hào),轉(zhuǎn)換為電壓值,然后通過(guò)ADC0832轉(zhuǎn)換后產(chǎn)生一個(gè)數(shù)字信號(hào)輸入到AT89C51單片機(jī)中進(jìn)行處理,再通過(guò)單片機(jī)驅(qū)動(dòng)PG160128A顯示壓力的相關(guān)信息。由于顯示程序的復(fù)雜性,所以選用了C語(yǔ)言作為開(kāi)放程序加快了開(kāi)發(fā)進(jìn)度。本次設(shè)計(jì)由于時(shí)間較為倉(cāng)促,難免考慮不周全,還有許多功能需要完善,這需要下來(lái)再去深究。在本次課程設(shè)計(jì)里面,我把電路和單片機(jī)必備的一些基本操作技能再次熟悉了一遍。對(duì)于壓力檢測(cè),我只進(jìn)行了最簡(jiǎn)單的程序編寫(xiě)和仿真,而往往在實(shí)際中是作為一個(gè)系統(tǒng)中的很小子環(huán)節(jié)來(lái)進(jìn)行應(yīng)用的,所以還需要我進(jìn)一步學(xué)習(xí)更多的單片機(jī)及相關(guān)測(cè)試傳感器知識(shí)。致謝本課題在選題及進(jìn)行過(guò)程中得到宋老師的悉心指導(dǎo)。論文行文過(guò)程中,宋老師多次幫助我分析思路,開(kāi)拓視角,在我遇到困難想放棄的時(shí)候給予我最大的支持和鼓勵(lì)。宋老師嚴(yán)謹(jǐn)求實(shí)的治學(xué)態(tài)度,踏實(shí)堅(jiān)韌的工作精神,將使我終生受益。再多華麗的言語(yǔ)也顯得蒼白。在此,謹(jǐn)向宋老師致以誠(chéng)摯的謝意和崇高的敬意。
