内蒙古工业大学课程设计说明书摘要本次课程设计的主要目的是用电子电路设计与实验热水锅炉温度控制器。让其实现在6-23时内85℃以下一、二号炉开始工作并报警，105℃以上一、二号炉停止工作并报警，冷却至95℃一号炉开始工作，且在此期间用LED显示温度和工作时间。本次主要用到的方法是用电压比较器实现模-数转换、用计数器实现控制电路和记录工作时间、用一系列的门电路实现一定的逻辑功能；借助Mulitisim软件进行电路仿真，再在实验室连接元器件实现设计要求。设计的结果是可以让一、二号炉在特定的温度和时间下按规定工作，同时温度显示和记录工作时间来辅助控制器的工作。有效的控制锅炉工作大大提高了生产效率，也可以起到控温的作用，在实际生活中有重要的实践意义。关键词：锅炉；温度；计时；运算电路。内蒙古工业大学课程设计说明书AbstractThemainpurposeofthiscoursedesignistousehotwaterboilertemperaturecontrolelectroniccircuitdesignandexperiment.Letactuallywithin6-23nowbelow85℃furnaceno.1andno.2tostartworkingandcallthepolice,above105℃furnaceno.1andno.2tostopworkandreporttothepolice,cooledto95℃furnacenumberonebeginstowork,andduringthisperiod,withLEDdisplaytemperatureandtimetowork.Themainlyusedmethodistousevoltagecomparatorimplementationmode-severaltransformations,counterisusedtoimplementcontrolcircuitandrecordtheworkingtime,aseriesofgateisusedtoimplementlogicfunction;InthelaboratoryusingMulitisimcircuitsimulationsoftware,andthenconnectcomponentstoachievethedesignrequirements.Designresultscanmakefurnaceno.1andno.2undercertaintemperatureandtimetoworkaccordingtoregulations,atthesametimetemperaturedisplayandrecordtheworkingtimetoassisttheworkofthecontroller.Effectivecontrolofboilerworkhasgreatlyincreasedtheproductionefficiency,alsocanhavetheeffectoftemperaturecontrol,hasimportantpracticalsignificanceinreallife.Keywords:Boiler;Temperature;Timing;Operationcircuit.内蒙古工业大学课程设计说明书目录一设计任务概概述···············································1二设计方案论证及方框图········································11设计方框图····················································12在实现电路时可以有多种方案····································3三电路组成及工作原理···········································51抑制共模信号电路和二阶低通滤波器······························52反向求和运算电路··············································63同向比例运算电路··············································64电压比较器·····················································65锅炉工作电路··················································7内蒙古工业大学课程设计说明书6多谐振荡器····················································87计时电路······················································88工作时间计时电路··············································99温度显示电路···············································...
