毕业设计论文-基于FPGA-的微波炉控制器设计

摘要本论文介绍了应用FPGA芯片和硬件描述语言(VHDL)设计微波炉控制器系统的方法。系统使用VHDL编程实现各底层模块的功能，顶层的设计采用图形输入完成。论文主要阐述模块化设计的思想和状态图的描述方法，以及他们在硬件描述语言中的应用，并展示了其在QuartusII开发系统下的仿真结果。微波炉控制器系统是一个实用型的系统，系统不仅具有操作简单的功能，而且烹调效果好，你可以按照固定程序烹调一些家常菜，可以采取分时、分不同级别火力加热，既能节约时间又能节约能源。主要有以下几个模块：输入模块、控制模块和显示模块。输入模块实现按键扫描和键盘译码、控制模块包括状态转换控制、数据装载、烹饪计时、温度控制、音效提示等等、显示模块涉及到显示译码和指示灯的闪烁。经过对系统做需求分析，详细功能设计、编码，模块连接，并利用FPGA实现相应的功能，经过波形仿真、下载调试，验证了设计方案的可行性及实现方法的有效性，基本实现了系统的要求。关键词：FPGA；VHDL；微波炉；状态图；定时器AbstractAbstractAbstractAbstractThispaperintroducesthemethodthatapplyingFPGAchipandVHDLtodesignthecontrolsystemofmicrowaveovens.ThesystemusesVHDLtofulfillthefunctionofeachbottommoduleandthedesignofthetoplayeriscompletedviagraphicentering.ThispapermainlyillustratestheideaofmoduledesignanddescriptionmethodofstatechartandthattheirapplicationinVHDLandsimulationresultsinthedevelopsystemofQuartusII.Microwavecontrollersystemisautility-typesystemthatincludesnotonlythefunctionofsimpleoperation,butalsogoodeffectofcook.Accordingtofixedroutine,youcancooksomehomelydishviatakingdifferenttimeanddifferentlevelfirepowertoheat,andthiscannotonlysavetime,butalsosaveenergy.Itmainlyincludesacoupleofmodulesasfollows:inputmodule,controlmoduleanddisplaymodule.Inputmodulefulfillskey-pressscanningandkeyboarddecoding,controlmoduleincludesstatusswitchingcontrol,dataloading,cooktime,temperaturecontrol,soundeffecttipandsoon,displaymodulecomesdowntodisplaycodingdecipherandtheflashingofindicatorlight.Throughtheanalysisofrequirement,detailedfunctiondesign,coding,moduleconnection,usingFPGAtofulfillrelevantfunction.Throughwaveformsimulation,downloaddebugging,itverifiesthefeasibilityofthedesignandtheeffectivenessofrealizationmethodandbasicallyfulfilltherequirementofthesystem.Keywords:Keywords:Keywords:Keywords:FPGA,VHDL,Microwaveoven,Statuschart,timerI目录1.绪论.................................................................................................................................11.1.任务的提出..........................................................................................................11.2.课题的内容和要求..............................................................................................11.3.设计的目的和意义..............................................................................................22.关键技术简介.................................................................................................................32.1.FPGA简介...........................................................................................................32.2.VHDL语言概述..................................................................................................32.3.QuartusII开发系统简介....................................................................................53.系统总体设计.................................................................................................................73.1.系统总体设计方案..............................................................................................73.2.系统功能模块描述..............................................................................................93.2.1.输入模块..................................................................................................103.2.2.控制模块..................................................................................................103.2.3.显示模块..................................................................................................113.3.系统的工作流程................................................................................................114.系统详细设计...............................................................................................................134.1.输入模块设计....................................................................................................134.1.1.键盘扫描..................................................................................................134.1.2.键盘译码..................................................................................................164.1.3.输入模块的实现......................................................................................174.2.控制模块设计....................................................................................................184.2.1.状态转换控制..........................................................................................194.2.2.数据装载..................................................................................................224.2.3.烹饪计时..................................................................................................234.2.4.温度控制..................................................................................................264.2.5.控制模块的实现......................................................................................294.3.显示模块设计....................................................................................................315.系统仿真.......................................................................................................................355.1.输入模块仿真.................................................................................
