锅炉自控系统工控软件监控设计I摘要锅炉的燃烧过程十分复杂，它是一个多参数对象，多扰动，各参数交叉影响的系统。燃烧系统内部的给煤、鼓风耦合性强，过程的非线性和大滞后也成了控制对象的难题，本系统采用选用亚控公司的Kingview软件作为前台程序设计进行实时监控。MicrosoftAccess作为后台数据库系统，用于保存故障、报警等数据。在使用上位机进行监控时，可以对系统的工作进行实时监控。可以通过对现场采集到的数据进行处理，以动画形式、报警处理、流程控制、实时曲线、历史曲线和报表输出等。在本次设计中系统采用了组态王6.52,该软件操作方便,结构清晰,易于上手。而且，它能充分利用Windows的图形编辑功能，方便地构成监控画面，并以动画方式显示控制设备的状态。关键词：组态王、锅炉、实时监控。AbstractTheboilercombustionprocessisextremelycomplex,itismorethanparametersobjects,multi-perturbation,variousparametersoverlappinginfluencesystem.Thecombustionsysteminteriorforthecoal,thedrumwindcouplingisstrong,theprocessnon-linearityandthebiglaghasalsobecomethecontrolledmemberdifficultproblem,thissystemusesselectstheYakongcompanyKingviewsoftwaretocarryonthereal-timemonitoringastheonstageprogramming.MicrosoftAccesstookthebackstagedatabasesystem,usesintopreservethebreakdown,thealarmingandsoonthedata.Thepositionmachinecarriesonthemonitoringwhentheuse,maycarryonthereal-timemonitoringtothesystemwork.Maythroughthedatawhichgatherstothescenecarryonprocessing,bytheanimationform,thealarmingprocessing,theflowcontrol,thereal-timecurve,thehistoricalcurveandthereportformoutputandsoon.Thesystemusedthekingview6.52,thissoftwareeaseofoperationinthisdesign,thestructurehasbeenclear,easyseatofhonor.Moreover,itcanfullyuseWindowsthegraphiceditorfunction,convenientlyconstitutesthemonitoringpicture,andbyanimationwaydisplaycontrolequipmentcondition.Keyword：KingviewBoilerReal-timemonitoring目录HYPERLINK\l"_Toc170359077"1绪论1HYPERLINK\l"_Toc170359078"1.1课题研究内容1HYPERLINK\l"_Toc170359079"1.2设计的目的和意义1HYPERLINK\l"_Toc170359080"1.3国内外相关技术的发展概况1HYPERLINK\l"_Toc170359081"1.4可行性分析2HYPERLINK\l"_Toc170359082"2锅炉工艺介绍3HYPERLINK\l"_Toc170359083"2.1概述3HYPERLINK\l"_Toc170359084"2.2基本控制系统介绍3HYPERLINK\l"_Toc170359085"2.2.1单参数调节系统3HYPERLINK\l"_Toc170359086"2.2.2串级调节系统4HYPERLINK\l"_Toc170359087"2.2.3前馈调节系统5HYPERLINK\l"_Toc170359088"2.3控制方案5HYPERLINK\l"_Toc170359089"3组态软件设计PAGEREF_Toc170359089\h11HYPERLINK\l"_Toc1703
