第二章 電子線路設(shè)計 畢業(yè)設(shè)計論文 4 第二章 電子線路設(shè)計 電路設(shè)計的基本原則 電子線路設(shè)計是指根據(jù)設(shè)計任務(wù)、要求和條件,選擇合適的方案,確定電路的總體組成框圖,接著對各單元進行設(shè)計,最后得到滿足技術(shù)指標(biāo)的功能要求的完整電路圖的過程。 制功率 ≤ 30W 的照明裝置。 第一章 課題設(shè)計概述 畢業(yè)設(shè)計論文 2 第一章 課題設(shè)計概述 課題要求 ,即當(dāng)周圍光線較弱(以人眼感官為準(zhǔn))時,能自動打開照明裝置,并根據(jù)周圍光線強度自動分級調(diào)節(jié)照明電路,同時具有聲控功能,通過開關(guān)置于聲控狀態(tài)時,能自動開啟照明電路,無聲時有一定時間的延時后自動關(guān)閉電源。我們小組同心協(xié)力,共同努力,最終得出成果,在此過程中,我們兩年所學(xué)的知識不斷完善,加強了我們對電路分析, 模擬電子技術(shù),數(shù)字電子技術(shù),實訓(xùn)電焊工藝的理解和鞏固。 本次設(shè)計 通過查閱書籍和資料, 以及 在老師和同學(xué)的幫助下, 最終完成太陽能警示電 路 。 利用聲光控延時開關(guān)來節(jié)約能源,適當(dāng)警示人們,比如在公共場所,有些設(shè)施方法不能停車,基于單片機的警示裝置來提醒人們這個地方不能停車。太陽能的利用有被動式利用(光熱轉(zhuǎn)換)和光電轉(zhuǎn)換兩種方式 , 太陽能發(fā)電 是一種新興 的可再生 方式 , 廣義上的太陽能是地球上許多能量的來源,如風(fēng)能,化學(xué)能,水的勢能等等。利用 太陽能作為電源, 太陽能 不像煤 和石油一樣用交通工具進行運輸,而是應(yīng)用光學(xué)原理,通過光的反射和折射進行直接傳輸,或者將太陽能轉(zhuǎn)換成其它形式的能量進行間接傳輸。 我們這次課題所要完成的是一種聲光控的野外警示裝置,應(yīng)用于生活中的各個方面。 關(guān)鍵字:單片機,太陽能電池板,聲控,光控 Abstract This article designs is one kind the open country police who controls based on 摘要 畢業(yè)設(shè)計論文 II the monolithic integrated circuit shows the installment the design and the manufacture, is bends down the solar energy power circuit by the light, the voice control electric circuit, the light controls the electric circuit, the monolithic integrated circuit control circuit, electric circuits and so on liquid crystal display electric circuit is posed, not only the main function is in order to realize the pedestrian passed by the construction road section when at night to have the display monitor to warn, but also some indicating lamps warned, nobody time any demonstration one kind of acoustooptics control device, this power source design for has not bent down using the light the solar energy board to the battery charging, again by the accumulator cell for the entire electric circuit power supply, fully has manifested the contemporary energy conservation environmental protection subject, both convenient and conserves energy. This design use monolithic integrated circuit and the discrete ponent mixture control, the structure is simple, cost low, ease of operation, overcame the existing acoustooptics controlling switch cost to be high, volume big and so on shortings, not only saved the fund, but also saved the energy, was the open country construction one kind reminds the police to show the installment. Key words: The monolithic integrated circuit, the solar cell board, the voice control, the light controls 目錄 緒論 ............................................................. 1 第一章 課題設(shè)計概述 ............................................... 2 課題要求 ......................................................................................................................2 課題方案 ......................................................................................................................2 畢業(yè)設(shè)計論文 一種光伏太陽能控制的野外警示裝置的設(shè)計與制作 III 圖 11 電路設(shè)計框圖 ................................................ 2 第二章 電子線路設(shè)計 ............................................... 4 電路設(shè)計的基本原則 ....................................................................................................4 理論分析 ......................................................................................................................4 電路分析 ......................................................................................................................4 光控電路模塊 .....................................................................................................4 聲控電路模塊 .....................................................................................................5 時鐘電路模塊 .....................................................................................................6 復(fù)位電路模塊 .....................................................................................................7 單片機模塊 .........................................................................................................8 電源電路模塊 .....................................................................................................9 燈電路模塊 .........................................................................................................9 顯示電路 .......................................................................................................... 10 系統(tǒng)的電路原理圖 ...................................................................................................... 11 第三章 涉及相關(guān)硬件介紹及設(shè)計 ..................................... 12 AT89C52單片機介紹 .................................................................................................. 12 單片機的主要功能特性 ............................................................................................... 12 單片機的特殊功能 ...................................................................................................... 14 AT89C52管腳說明 ...................................................................................................... 14 光敏電阻 ................................................................................................................... 16 駐極體話筒 ................................................................................................................ 17 液晶的介紹 ................................................................................................................ 18 ................................................................................................
