【文章內(nèi)容簡介】 溫度值取補(bǔ)碼置“”標(biāo)溫度零下？ 圖34 設(shè)計溫度子程序具體源程序詳見附錄二。四、仿真與調(diào)試(一)軟件調(diào)試軟件調(diào)試的主要任務(wù)是排查錯誤，其中錯誤類型主要包括邏輯錯誤和功能錯誤，有些錯誤是顯性的，而有些是隱形的，可以通過仿真開發(fā)系統(tǒng)發(fā)現(xiàn)逐步改正。Proteus軟件可以對以微控制器的設(shè)計和所有的周圍電子器件一起仿真為基礎(chǔ)，用戶甚至可以實(shí)時采用例如LED/LCD、鍵盤等動態(tài)外設(shè)模型來對設(shè)計進(jìn)行交互的仿真。Proteus支持的微處理芯片包括8051系列、AVR系列、PIC系列、HC11系列及Z80等等。Proteus可以完成單片機(jī)系統(tǒng)原理圖電路繪制，更為顯著的特點(diǎn)是可以與keil軟件結(jié)合進(jìn)行編程仿真調(diào)試。本系統(tǒng)的調(diào)試主要以軟件為主，其中，系統(tǒng)電路圖的繪制和仿真采用Proteus軟件，而程序方面，用源程序，用Keil軟件將程序?qū)懭雴纹瑱C(jī)。程序無誤。程序?qū)懭雴纹瑱C(jī)顯示正確結(jié)果 見圖41。圖41 程序?qū)懭雴纹瑱C(jī)顯示正確結(jié)果 上下限默認(rèn)為10℃～30℃時 顯示屏中S代表上限，X代表下限。當(dāng)溫度為11℃時，燈不閃爍，不報警。見圖42。 圖42 顯示11℃，不報警當(dāng)溫度為31℃，超過上下限，燈閃爍報警。見圖43。圖43 超過上限報警調(diào)節(jié)按鍵開關(guān)改變上下限，使S=28 X=16。將“上限減一”鍵按2下，“下限加一”鍵按6下，可以得到S=28 X=16。當(dāng)溫度為11℃，燈閃爍報警。 見圖44。 圖44 低于下限報警五、總結(jié)通過仿真測試結(jié)果可以看出，本次設(shè)計的數(shù)字溫度計能夠迅速顯示溫度的測量值，LCD能夠顯示10℃～100℃的溫度，精度誤差小于1℃，、可以設(shè)置報警溫度的上下限，當(dāng)實(shí)測溫度超過設(shè)定范圍時，LED燈能自動閃爍、報警，整個系統(tǒng)已經(jīng)基本實(shí)現(xiàn)了預(yù)期設(shè)計目標(biāo)。在這次設(shè)計中，我們運(yùn)用了以前學(xué)過的專業(yè)課知識，如：proteus仿真、源程序、模擬和數(shù)字電路知識等。具體到設(shè)計時，我遇到了不少問題，例如如何選擇核心器件，單片機(jī)的引腳分配，各功能模塊電路的接口如何設(shè)計、源程序的流程設(shè)計等等。通過不斷的深入思考，問題的解決，我對所學(xué)知識有了更深入的認(rèn)識與理解，并能活學(xué)活用，開闊了視野，很好的提高了自身的專業(yè)技能。要做好畢業(yè)論文，就必須做到：在程序設(shè)計之前，要對所用單片機(jī)的內(nèi)部結(jié)構(gòu)有一個系統(tǒng)的了解，知道所選單片機(jī)所含哪些有用的資源；需要一個明確的思路和一個完整的軟件設(shè)計流程圖；在程序設(shè)計時，不可能一次將整個程序設(shè)計好，需要經(jīng)過反復(fù)的修改、不斷的改進(jìn)，這是設(shè)計程序的必經(jīng)之路。在這次的課程設(shè)計中，我真正的意識到，在以后的學(xué)習(xí)中，要理論聯(lián)系實(shí)際，把我們所學(xué)的理論知識用到實(shí)際當(dāng)中，知識只有結(jié)合實(shí)踐才能化為成就與力量，這就是此次課程設(shè)計的最大收獲。六、致謝通過這一階段的努力，我的畢業(yè)論文終于完成了，這意味著大學(xué)生活即將結(jié)束。在大學(xué)階段，我在學(xué)習(xí)上和思想上都受益非淺，這除了自身的努力外，與各位老師、同學(xué)和朋友的關(guān)心、支持和鼓勵是分不開的。在我寫本論文的過程中，羅老師對我實(shí)踐中出現(xiàn)的問題給予耐心的解答，完稿之后在百忙之中仔細(xì)閱讀，給出修改意見，羅老師犧牲休息時間給予我的認(rèn)真輔導(dǎo)，以及她負(fù)責(zé)的態(tài)度，讓我很受鼓舞！在此對她表示感謝。 最后，再次向所有關(guān)心支持指導(dǎo)幫助過我完成論文的老師和同學(xué)，表示最誠摯的謝意！七、參考文獻(xiàn)[1][J].電子測量技術(shù), 2007，810.

With heaps of time, the sevenday Chinese為你提供優(yōu)秀的畢業(yè)論文設(shè)計參考資料，請您刪除一下內(nèi)容，O(∩_∩)O謝謝?。。ational Day holiday could be the best occasion to enjoy a destination. However, it can also be the easiest way to ruin how you feel about a place and you may bee more fatigued after the holiday, due to battling the large crowds. During peak season, a dream about a place can turn to nightmare without careful planning, especially if you travel with children and older people. As most Chinese people will take the holiday to visit domestic tourist destinations, crowds and busy traffic are inevitable at most places. Also to be expected are increasing transport and acmodation prices, with the possibility that there will be no rooms available. It is also mon that you39。llwait in the line for one hour to get a ticket, and another two hours at the site, to only see a tiny bit of the place due to the crowds. Last year, 428 million tourists traveled in China over the weeklong holiday in October. Traveling during this period is a matter that needs thorough preparation. If you are short on time to plan the uping Golden Week it may not be a bad idea to avoid some of the most crowded places for now. There is always a place so fascinating that everyone yearns for. Arxan is a place like this. The beauty of Arxan is everlasting regardless of the changing of four seasons. Bestowed by nature, its spectacular seasonal landscape and mountains are just beyond word. Arxan is a crucial destination for the remended travelling route, China Inner Mongolia Arxan — Hailar — Manzhouli. It is also the joint of the four prairies across the SinoMongolian border, where people gravitate towards the exotic atmosphere mixed with Chinese, Russian, and Mongolia elements. As a historic site for the Yitian Battle, Arxan still embodies the spirit of Genghis Khan. Walking into Arxan, you will be amazed by a kaleidoscope of gorgeous colors all the year round the Spring azaleas blooming red in the snow, the Summer sea wavering blue in the breeze, the Autumn leaves painted in yellow covering volcanic traces, and the Winter woods shining white on the vast alpine snowscape. Hinggan League Arxan city is situated in the far eastern area of Inner Mongolia Autonomous Region. Its full name Haren Arxan means hot holy water in the Mongolian language. Arxan is a tourism city in the northern frontier with a blend of large forest, grand prairies, vast snowfield, heaven lake cluster, thermium, as well as volcanic cluster. It is a rare and unique ecotourism base filled with healthy sunshine, clean air and unspoiled green. Nestled close to the country39。s largest virgin forest, and known for its spring and ecological environment, Arxan is marveled at by many tourists as the purest land on earth. You cannot miss out the Autumn of Arxan. It is definitely the best with brightlycolored scenery full of emotions. Autumn in the northern part of the country es earlier than the South.
