【正文】 摘 要本次課程設(shè)計(jì)的主要目的是用電子電路設(shè)計(jì)與實(shí)驗(yàn)熱水鍋爐溫度控制器。讓其實(shí)現(xiàn)在623時(shí)內(nèi)85℃以下一、二號(hào)爐開始工作并報(bào)警， 105℃以上一、二號(hào)爐停止工作并報(bào)警，冷卻至95℃一號(hào)爐開始工作，且在此期間用LED顯示溫度和工作時(shí)間。本次主要用到的方法是用電壓比較器實(shí)現(xiàn)模數(shù)轉(zhuǎn)換、用計(jì)數(shù)器實(shí)現(xiàn)控制電路和記錄工作時(shí)間、用一系列的門電路實(shí)現(xiàn)一定的邏輯功能；借助Mulitisim軟件進(jìn)行電路仿真，再在實(shí)驗(yàn)室連接元器件實(shí)現(xiàn)設(shè)計(jì)要求。設(shè)計(jì)的結(jié)果是可以讓一、二號(hào)爐在特定的溫度和時(shí)間下按規(guī)定工作，同時(shí)溫度顯示和記錄工作時(shí)間來輔助控制器的工作。有效的控制鍋爐工作大大提高了生產(chǎn)效率，也可以起到控溫的作用，在實(shí)際生活中有重要的實(shí)踐意義。關(guān)鍵詞：鍋爐；溫度；計(jì)時(shí)；運(yùn)算電路。 AbstractThe main purpose of this course design is to use hot water boiler temperature control electronic circuit design and experiment. Let actually within 623 now below 85 ℃ furnace no. 1 and no. 2 to start working and call the police, above 105 ℃ furnace no. 1 and no. 2 to stop work and report to the police, cooled to 95 ℃ furnace number one begins to work, and during this period, with LED display temperature and time to work. The mainly used method is to use voltage parator implementation mode several transformations, counter is used to implement control circuit and record the working time, a series of gate is used to implement logic function。 In the laboratory using Mulitisim circuit simulation software, and then connect ponents to achieve the design requirements. Design results can make furnace no. 1 and no. 2 under certain temperature and time to work according to regulations, at the same time temperature display and record the working time to assist the work of the controller. Effective control of boiler work has greatly increased the production efficiency, also can have the effect of temperature control, has important practical significance in real life.Keywords: Boiler。 Temperature。 Timing。 Operation circuit.28 / 34目 錄一 設(shè)計(jì)任務(wù)概概述1二 設(shè)計(jì)方案論證及方框圖11 設(shè)計(jì)方框圖12 在實(shí)現(xiàn)電路時(shí)可以有多種方案3三 電路組成及工作原理51 抑制共模信號(hào)電路和二階低通濾波器52 反向求和運(yùn)算電路63 同向比例運(yùn)算電路64 電壓比較器65 鍋爐工作電路76 多諧振蕩器
