精品基于单片机的异型水箱仿真装置论文

题目：基于单片机的异型水箱仿真装置I基于单片机的异型水箱仿真装置摘要本设计的研究对象是以单片机为核心的异型水箱仿真装置，在为这一系统进行软硬件设计的过程中，发现和总结了一些实际问题，并通过解决这些问题，就异型水箱数学模型的建立、仿真装置硬件设计、软件设计展开讨论，力争在理论分析和实际应用上有所创新。异型水箱仿真装置的核心是围绕异型水箱的数学模型来体现异型水箱的特性，并通过软件实现整个异型水箱的工作状态和功能。对异型水箱数学模型的建立是本文工作的重点。异型水箱属于过程控制系统实验装置中的被控对象。由于被控对象的特性直接影响到整个系统的控制质量，所以其数学模型的建立非常重要。设计中通过机理演绎法推导并建立了其数学模型，并设计出了仿真装置。关键词：单片机；异型水箱；数学模型IIStudyonTheSimulationSetofShapedWaterBoxBasedonMCUAbstractTheobjectofthispaperisasimulationsetofshapedwaterboxbasedonMCU.Intheprocessofdesigningonsoftwareandhardwareforthesystem,afewpracticalproblemshavebeenfound.Tosolvetheseproblems,wediscussthemathematicalmodelbuilding,thedesigningonhardwareandsoftware,andwanttodevelopsomenewconclusionsinpracticeandtheory.Thecoreofthesimulationsetofshapedwaterboxistoshowthecharacteristicofshapedwaterboxaccordingtoitsmathematicmodel,andrealizesitsdutyandfunctionbysoftwaredesigning.Thehighlightofthispaperistobuildupthemathematicalmodeloftheshapedwaterbox.Theshapedwaterboxbelongstoacontrolledmemberofprocesscontrolsystemintheexperimentinstallation.Sincethecharacteristicofthecontrolledmemberdirectlyinfluencesthequalityofthewholesystem,soitisveryimportantthatthemathematicalmodeloftheshapedwaterboxisbuilt.Wehavededucedandbuiltitsmathematicmodelbyadoptthedeductivemethod,andwehavedesignedthedevicetosimulatetheshapedwaterbox.Keywords:MCU;Shapedwaterbox;MathematicmodelIII目录摘要.............................................................................................................................................IAbstract.....................................................................................................................................II第一章绪论..............................................................................................................................11.1研究背景.....................................................................................................................11.2课题的目的及研究的主要内容.................................................................................11.3课题的意义.................................................................................................................2第二章异型水箱数学模型的建立..........................................................................................42.1过程建模的介绍.........................................................................................................42.2单容过程的建模.........................................................................................................62.3异型水箱数学模型的建立.........................................................................................92.3.1建立异型水箱数学模型的方法......................................................................92.3.2异型水箱数学模型的建立............................................................................11第三章基于单片机的异型水箱仿真装置硬件设计............................................................163.1系统硬件的总体设计...............................................................................................163.2中央控制部件...........................................................................................................163.2.1中央控制部件的选择....................................................................................163.2.2AT89C52的封装形式与引脚.........................................................................173.2.3AT89C52的基本电路.....................................................................................183.2.4AT89C52的口线分配.....................................................................................193.3串行程序存储器.......................................................................................................203.3.1X25045的引脚排列及引脚说明...................................................................203.3.2X25045芯片功能...........................................................................................22IV3.3.3X25045工作原理...........................................................................................223.3.4X25045与AT89C52的接口电路..................................................................233.4模数转换部件...........................................................................................................233.4.1模数转换部件的选择....................................................................................233.4.2TLC0832引脚分配.........................................................................................243.4.3TLC0832配置位说明.....................................................................................243.4.4TLC0832时序分析.........................................................................................253.4.5TLC0832与AT89C52的接口电路...............................................................263.5人机接口部件...........................................................................................................263.5.1输出显示........................................................................................................263.5.2键盘输入........................................................................................................283.5.3液位报警.................................................
