4、保護(hù)模塊，下面分別論證這幾個(gè)模塊的選擇。1.1 主控模塊的論證與選擇方案一：選用51單片機(jī)作為控制器。A/D芯片采集負(fù)載RL的電流經(jīng)程序計(jì)算控制彩屏顯示功率。但51單片機(jī)處理速度慢，內(nèi)部無A/D需外加電路，電路復(fù)雜。方案二：選用凌陽公司的SPCE061A單片機(jī)作為控制器。SPCE061A是16位的處理器，單片機(jī)運(yùn)算能力強(qiáng)，但該單片機(jī)的應(yīng)用不是十分靈活，操作不熟練。方案三：選用TI公司 MSP430F5438A作為控制器。內(nèi)部A/D采集負(fù)載RL的電流經(jīng)程序計(jì)算控制彩屏顯示功率，無外加A/D芯片電路簡(jiǎn)單，且處理速度快，功耗低。綜合以上三種方案，選擇方案三。1.2 電源穩(wěn)壓模塊的論證與選擇方案一：選

5、用LM2596開關(guān)電壓調(diào)節(jié)器。它是降壓型電源管理單片集成電路，能夠輸出3A的驅(qū)動(dòng)電流，同時(shí)具有很好的線性和負(fù)載調(diào)節(jié)特性。方案二：選用L7805三端穩(wěn)壓芯片。它所需的外圍元件極少，電路內(nèi)部還有過流、過熱及調(diào)整管的保護(hù)電路，但帶負(fù)載能力不強(qiáng)。方案三：選用TPS5450穩(wěn)壓芯片。它有5.5V至36V寬輸入電壓范圍，5A的輸出電流，帶負(fù)載能力強(qiáng)。綜合以上三種方案，選擇方案三。1.3顯示模塊的論證與選擇方案一：采用數(shù)碼管顯示。數(shù)碼管功耗較大，顯示內(nèi)容單一，不易控制。方案二：采用12864圖形液晶顯示屏。內(nèi)部自帶字庫(kù)方便操作，但顏色單一無法顯示出比較好看的界面。方案三：采用2.4寸TFT液晶彩屏?？梢燥@示

6、任意顏色文字，或者彩色圖片。綜合以上三種方案，選擇方案三。2系統(tǒng)理論分析與計(jì)算21系統(tǒng)理論的分析2.1.1直流穩(wěn)壓電源分析 此系統(tǒng)設(shè)計(jì)的直流穩(wěn)壓電源要求輸入電壓在5V25V范圍內(nèi)，穩(wěn)壓模塊帶負(fù)載電阻5歐輸出電壓為5V±0.05V，電壓調(diào)整率為Su1%，連接方式不變，負(fù)載電阻值固定為5。當(dāng)直流輸入電壓在5.57V 變化時(shí)，輸出電壓為5 V±0.05V 連接方式不變，直流輸入電壓固定在7V，當(dāng)直流穩(wěn)壓電源輸出電流由 1A 減小到0.01A 時(shí)，要求負(fù)載調(diào)整率S1%。選用TPS5450穩(wěn)壓芯片，制作穩(wěn)壓電源模塊。2.1.2漏電檢測(cè)電路分析漏電保護(hù)部分要求設(shè)計(jì)一個(gè)動(dòng)作電流為30mA

7、的漏電保護(hù)裝置，使用穩(wěn)壓電源進(jìn)行供電，電路負(fù)載20，設(shè)計(jì)一條由毫安級(jí)電流表和可調(diào)電阻R構(gòu)成的漏電支路，當(dāng)調(diào)節(jié)電阻R使漏電支路電流為30mA時(shí)，漏電保護(hù)動(dòng)作，切斷主控電路并使得RL電阻兩端電壓為0V。比較運(yùn)算放大器采集的電壓值與計(jì)算設(shè)定的基準(zhǔn)電壓進(jìn)行比較放大，利用輸出電壓控制晶閘管導(dǎo)通，使繼電器吸合，從而斷開主電路進(jìn)行保護(hù)。2.1.3關(guān)斷保護(hù)電路的分析要求檢測(cè)到漏電后要使RL兩端電壓為0V并保持自鎖，排除故障后按K鍵恢復(fù)輸出。使用晶閘管控制繼電器關(guān)斷電路，正好利用晶閘管“觸發(fā)導(dǎo)通，導(dǎo)通不觸發(fā)”的這個(gè)特性，當(dāng)晶閘管導(dǎo)通使繼電器常閉觸點(diǎn)斷開電路之后。電路一直保持保護(hù)狀態(tài)，只有按下K鍵讓晶閘管關(guān)斷，再

8、使繼電器常閉觸點(diǎn)閉合從而使電路恢復(fù)輸出。2.2 系統(tǒng)理論的計(jì)算 2.2.1電源電路參數(shù)計(jì)算為了滿足題目要求采用TPS5450模塊作為電源穩(wěn)壓芯片。它輸入電壓5.5V-36V,最大工作電流5A 。通過在輸出端并接一個(gè)固定電阻一個(gè)電位器，調(diào)節(jié)電位器就可以輸出不同的電壓。2.2.2漏電檢測(cè)電路參數(shù)計(jì)算題目要求檢測(cè)30mA的漏電流因?yàn)榭紤]到信號(hào)較小，所以先采用運(yùn)放OPA335進(jìn)行放大，在通過比較器進(jìn)行比較，觸發(fā)可控硅來達(dá)到控制漏電的動(dòng)作。當(dāng)輸入漏電流高于30mA則觸發(fā)可控硅，關(guān)斷主回路，達(dá)到保護(hù)的作用。若輸入漏電流小于30mA則可控硅不觸發(fā)。2.2.3關(guān)斷保護(hù)電路參數(shù)計(jì)算 在漏電保護(hù)中，由于可控硅的導(dǎo)

9、通保持特性，需要一個(gè)觸發(fā)信號(hào)才能退出，所以，在按下復(fù)位鍵，就退出了漏電保護(hù)狀態(tài)。3電路與程序設(shè)計(jì)3.1電路的設(shè)計(jì)3.1.1系統(tǒng)總體框圖系統(tǒng)總體框圖如圖所示：圖3.1.1 直流穩(wěn)壓電源電路原理圖3.1.2 控制系統(tǒng)電路原理圖圖3.1.2 控制系統(tǒng)電路電路原理圖3.1.3 TFT彩屏顯示電路原理圖圖3.1.3 TFT彩屏顯示電路原理圖3.1.4直流穩(wěn)壓電源電路原理圖調(diào)整R2和R3的阻值可以調(diào)整輸出電壓。輸入輸出用固態(tài)電容和獨(dú)石電容有效出濾除干擾及紋波。圖3.1.4 直流穩(wěn)壓電源電路原理圖3.1.5功率測(cè)量電路原理圖 采樣電阻R6用康銅絲繞制，最大程度減小溫差，經(jīng)R6采樣通過LM358放大輸出讓AD
