5、------------------------------------------------------12一、實(shí)訓(xùn)目的通過(guò)電子產(chǎn)品設(shè)計(jì)與制作（實(shí)訓(xùn)），系統(tǒng)地進(jìn)行電子工程實(shí)踐和技能訓(xùn)練，培養(yǎng)理論與實(shí)踐相結(jié)合的能力，提高獨(dú)立思考、分析和解決電子電路實(shí)際問(wèn)題的能力。同時(shí)，鞏固、擴(kuò)展電子元器件及電子產(chǎn)品安裝專業(yè)知識(shí)；掌握產(chǎn)品維修和維護(hù)的基本方法，實(shí)現(xiàn)知識(shí)向能力的轉(zhuǎn)化，提高實(shí)踐動(dòng)手能力。二、實(shí)訓(xùn)要求1、學(xué)會(huì)看圖、識(shí)圖，了解簡(jiǎn)單電子產(chǎn)品的實(shí)現(xiàn)過(guò)程。2、能夠自己安裝、焊接和調(diào)試簡(jiǎn)單的電子電路產(chǎn)品并學(xué)會(huì)使用測(cè)量?jī)x器測(cè)量電路。3、學(xué)會(huì)分析電路，排除

6、電路故障的方法。學(xué)會(huì)記錄和處理實(shí)驗(yàn)數(shù)據(jù)、說(shuō)明實(shí)驗(yàn)結(jié)果，撰寫實(shí)驗(yàn)報(bào)告。4、能夠使用計(jì)算機(jī)進(jìn)行印刷電路板的設(shè)計(jì)。5、培養(yǎng)嚴(yán)謹(jǐn)?shù)目茖W(xué)態(tài)度，耐心細(xì)致的工作作風(fēng)和主動(dòng)研究的探索精神。三、實(shí)訓(xùn)環(huán)境江西工業(yè)工程職業(yè)技術(shù)學(xué)院實(shí)驗(yàn)樓302實(shí)驗(yàn)室（焊接室）實(shí)驗(yàn)樓401實(shí)驗(yàn)室（仿真室）四、實(shí)訓(xùn)內(nèi)容（1）數(shù)碼管七段數(shù)碼管一般由8個(gè)發(fā)光二極管組成，其中由7個(gè)細(xì)長(zhǎng)的發(fā)光二極管組成數(shù)字顯示，另外一個(gè)圓形的發(fā)光二極管顯示小數(shù)點(diǎn)。當(dāng)發(fā)光二極管導(dǎo)通時(shí)，相應(yīng)的一個(gè)點(diǎn)或一個(gè)筆畫發(fā)光?？刂葡鄳?yīng)的二極管導(dǎo)通，就能顯示出各種字符，盡管顯示的字符形狀有些失真，能顯示的數(shù)符數(shù)量也有限，

7、但其控制簡(jiǎn)單，使用也方便。發(fā)光二極管的陽(yáng)極連在一起的稱為共陽(yáng)極數(shù)碼管，陰極連在一起的稱為共陰極數(shù)碼管，如圖所示。數(shù)碼顯示管實(shí)物圖七段發(fā)光顯示器結(jié)構(gòu)(共陰共陽(yáng))（2）74LS4874ls48芯片是一種常見的七段數(shù)碼管譯碼驅(qū)動(dòng)器，常用在各種數(shù)字電路和單片機(jī)系統(tǒng)的顯示系統(tǒng)中，下面我就給大家介紹一下這個(gè)元件的衣些參數(shù)和應(yīng)用技術(shù)等資料。74ls48引腳實(shí)物圖74ls48邏輯功能表（3）74LS160同步十進(jìn)制計(jì)數(shù)器74LS160作用：實(shí)現(xiàn)計(jì)時(shí)的功能，為脈沖分配器做好準(zhǔn)備。74LS160結(jié)構(gòu)和功能160為十進(jìn)制計(jì)數(shù)器，直接清零。簡(jiǎn)要說(shuō)明:160為可

8、預(yù)置的十進(jìn)制計(jì)數(shù)器，共有54/74160和54/74LS160兩種線路結(jié)構(gòu)型式,其主要電器特性的典型值。下面是74LS160的主要電器特性：異步清零端/MR1為低電平時(shí)，不管時(shí)鐘端CP信號(hào)狀態(tài)如何，都可以完
