内蒙古科技大学毕业设计说明书--内蒙古科技大学毕业设计说明书毕业设计说明书（毕业论文）高炉冷却水温度测量系统设计摘要高炉冷却水进出水温度的变化，间接反映出炉内的物料和冶炼状况，高炉冷却水温差过大反映了炉壁温度过高，严重影响高炉的寿命，但温差过小则能源损失太大，增加冶炼成本。通过在线实时监测水温差的变化，可监测到高炉冷却壁的使用状态，及时对冷却壁进行维护，可提高高炉的使用寿命、减少高炉事故的发生，降低能耗，提高产量。因此，高炉冷却水温差的测量是高炉冶炼的重要操作之一。本设计是基于单片机的温度测量系统，系统具有高精度、功能强、经济性好的特点，无论在提高产品质量还是产品数量，节约能源，还是改善劳动条件等方面都显示出它的优越性。本设计以单片机为核心，硬件电路分为：扩展模块、测量模块、数据转换模块、键盘与显示模块、电源和报警模块，系统通过软、硬件的设计，完成对高炉16路冷却水温度进行自动巡回检测，需要时用键盘切换电子钟和显示温差，被测温差不在规定范围内，系统报警。关键字：高炉多路开关放大滤波模数转换笔段码BlastfurnacecoolingwatertemperaturemeasurementsystemAbstractThecoolingwatertemperaturechangesofBlastfurnace,indirectlyreflectsthestatusofthefurnaceandsmeltingofmaterials,blastfurnacecoolingwatertemperaturedifferencereflectsthefurnacewalltemperatureistoohigh,seriouslyaffectingthelifeofblastfurnace,if,thetemperaturedifferenceintheenergylossistoosmalltoincreasesmeltingcosts.Onlinereal-timemonitoringofchangesinwatertemperaturecanbemonitoredusingthestateofblastfurnacestave,timelymaintenanceofthecoolingwall,canimprovetheservicelifeofblastfurnace,blastfurnacetoreduceaccidents,reduceenergyconsumptionandincreaseproduction.Therefore,theblastfurnacecoolingwatertemperaturemeasurementisanimportantoperationofblastfurnacesmelting.ThisdesignisatemperaturemeasurementsystembasedonMCUchip,thesystemhasmanyadvantagesincludinghighprecision,Gongnengstrong,economygoodfeatures,whetherimprovingproductqualityandquantityenergyconservation,ortoimprovetheworkingconditions,thesystemallshowitsadvantages.ToMCUasthecoredevice,thehardwarecircuitisdividedinto:extensionmodules,measurementmodules,dataconversionmodule,keyboardanddisplaymodule,powersupplyandalarmmodules,thesystemcompleteblastfurnacecoolingwatertemperatureof16toautomaticallydetectcircuitthroughsoftwareandhardwaredesign,ifthesustemneedtoswitchtheclock,wecanusethekeyboardanddisplaytemperatureandmeasuredtemperatureisnotwithinthescope,thesystemneedtoalarm.Keywords:Blastfurnace、Multi-switch、Amplifyingandfiltering、ADC、Strokescode目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc264702803"摘要PAGER
