【正文】 摘 要本次課程設(shè)計的主要目的是用電子電路設(shè)計與實驗熱水鍋爐溫度控制器。讓其實現(xiàn)在623時內(nèi)85℃以下一、二號爐開始工作并報警， 105℃以上一、二號爐停止工作并報警，冷卻至95℃一號爐開始工作，且在此期間用LED顯示溫度和工作時間。本次主要用到的方法是用電壓比較器實現(xiàn)模數(shù)轉(zhuǎn)換、用計數(shù)器實現(xiàn)控制電路和記錄工作時間、用一系列的門電路實現(xiàn)一定的邏輯功能；借助Mulitisim軟件進(jìn)行電路仿真，再在實驗室連接元器件實現(xiàn)設(shè)計要求。設(shè)計的結(jié)果是可以讓一、二號爐在特定的溫度和時間下按規(guī)定工作，同時溫度顯示和記錄工作時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，在實際生活中有重要的實踐意義。關(guān)鍵詞：鍋爐；溫度；計時；運算電路。 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)計任務(wù)概概述1二 設(shè)計方案論證及方框圖11 設(shè)計方框圖12 在實現(xiàn)電路時可以有多種方案3三 電路組成及工作原理51 抑制共模信號電路和二階低通濾波器52 反向求和運算電路63 同向比例運算電路64 電壓比較器65 鍋爐工作電路76 多諧振蕩器
