1虚拟仿真在线实验教学及管理系统设计摘要当今的社会是信息化的社会，计算机网络的发展更是日新月异。伴随着网络的高速发展，在线实验教学及管理的教学模式也随着发展，变得更加复杂，原因主要有两点：不断涌现出许多不同的新设备；这些设备需要支持许多不同的协议。在线实验教学及管理教学模式的研究是伴随着网络不断发展而形成的一大热点。随着电子技术的不断发展,电子类课程在高教中的地位日趋重要。而作为该类课程教学重要组成部分的实验教学，也越来越受到了人们的重视。它对于提高教学质量，培养学生的实际动手能力及创新思维能力具有无可比拟的作用。长期以来，高教研究者、工作者一直为此探索，并希望找到一个行之有效的方法。为此，人们借助现有的电子技术手段，建立了多种门类的实验平台（如电路分析实验室、模拟电子线路实验室、数字电路实验室、信号与系统实验室等），并在此平台上开设了相应的实验课程。尽管如此，这些措施并未达到预期的效果。特别是在电子技术高速发展的今天，这些方法及手段已经显得不再适宜，建立一套新的实验手段及方法已成为高教研究者、工作者的共识。本文主要内容如下：1．介绍了在线实验教学及管理系统的基本特点及其体系结构，对比分析了国内、外知名的在线实验教学及管理系统，并简单对系统进行了业务分析，总体要求分析，功能需求分析，给出系统用例图，系统时序图，重点阐述了本系统提供了在线实验、教学论坛、站内消息、教学活动管理、虚拟实验管理、实验智能指导、实验结果自动批改、实验报告电子化管理、教学过程监督、教学效果评价等功能。2、依据需求分析进行了系统架构设计，给出了开发框架、技术架构和应用结构，采用功能结构图、顺序图等工具阐述了系统功能设计，给出了数据库表结构。【关键词】在线实验实验教学教学管理.2AbstractToday'ssociety,informationsociety,thedevelopmentofcomputernetworksischanging.Alongwiththerapiddevelopmentofthenetwork,theteachingmodeofteachingandmanagementofonlineexperimentswiththedevelopmentbecomesmorecomplex,therearetwomainreasons:emergingoutofmanydifferentdevices;thesedevicesneedtosupportmanydifferentprotocols.Onlineteachingandmanagementofexperimentalteachingmodelalongwiththenetworkdevelopmentandtheformationofahottopic.Withthecontinuousdevelopmentofelectronictechnology,electroniccoursesinhighereducationwillbecomemoreimportant.Importantasclassteachingpartoftheexperimentalteaching,moreandmorepeople'sattention.Ithasanunparalleledroleinimprovingthequalityofteachingandtodevelopstudents'practicalabilityandcreativethinkingability.Alongtime,highereducationresearchers,workershavebeenexploringthisend,andhopetofindaneffectiveway.Tothisend,withtheexistingelectronictechniques,theestablishmentofaplatformforavarietyofcategoriesofexperimentallaboratory(suchascircuitanalysis,analogelectroniccircuitslaboratory,digitalcircuitlab,SignalsandSystemsLaboratory,etc.),andonthisplatformontheopeningoftheexperimentalcourse.Nevertheless,thesemeasuresdidnotachievethedesiredresults.Especiallyintherapiddevelopmentofelectronictechnologytoday,thesemethodsandmeanshaveseemednolongerappropriate;theestablishmentofanewsetofexperimentaltoolsandmethodshasbecometheconsensusofthehighereducationresearchers,workers.Themaincontentofthispaperisasfollows:1.onlineexperimentalteachingandthebasiccharacteristicsofthemanagementsystemanditsarchitecture,comparativeanalysisofdomesticandforeignwell-knownonlineexperimentteachingandmanagementsystems,andsystembusinessanalysis,theoverallrequirementsanalysis,functionalrequirementsanalysis,givencasediagram,systemtimingdiagram,focusingonelaboratedthissystemprovidesonlineexperimentteachingforums,newsstation,themanagementofteachingactivitiesandknowledgeassistedlearning,themanagementofvirtualexperiments,experimentsintelligentguidance,experimentalresultsautomaticallycorrecting,experimentalreporton3electronictechnologymanagement,supervisionoftheteachingprocess.2.Basedonneedsanalysis,systemarchitecturedesign,giventhedevelopmentframework,technologyarchitectureandapplicationstructure,functionalstructurediagram,sequencediagramandothertoolsonthesystemfunctionaldesign,giventhestructureofthedatabasetable.Keywords:0nlineexperimentsExperimentalteachingTeachingmanagement.4目录摘要..........................................................1Abstract.........................................................2目录.............................................................4第一章绪论......................................................61.1课题研究背景和意义.......................................61.1.1研究背景...........................................61.1.2研究意义...........................................71.2国内外研究现状和应用分析.................................81.3系统特点.................................................91.3.1内涵...............................................91.3.2特点..............................................101.4本文的组织构架..........................................10第二章相关技术综述.............................................112.1Java技术................................................112.2ActiveX技术.............................................142.3VRML技术................................................162.4Mysql技术...............................................18第三章系统需求分析............................................203.1系统业务分析............................................203.1.1角色分析..........................................203.1.2系统业务流程分析..................................223.2系统功能需求分析........................................253.3在线实验教学内容需求....................................393.4数据需求分析............................................40第四章系统设计..................................................424.1系统功能结构设计........................................424.1.1在线实验功能设计..................................424.1.2教学论坛功能设计..................................484.1.3站内消息功能设计..................................504.1.4用户管理功能设计..................................514.1.5知识库维护功能设计................................544.2在线实验设计............................................554.2.1电路分析虚拟实验的设计............................554.2.2模拟电路虚拟实验的设计............................584.2.3数字电路与逻辑设计虚拟实
