一体化电子白板班班通解决方案[1]

数字一体化电子白板班班通解决方案1系统概述采用交互式电子白板的互动教学模式呈现不断上升的趋势，互动教学必将主导未来教学的新模式。电子白板是无法独立进行互动教学的，要实现电子白板进行“班班通”建设，则必须要配套其他教学设备。例如：计算机、投影仪、音响系统等，这些分离设备增加的同时，也意味着也必须通过布线工程将其连接起来，这样，才能满足教学使用要求。“紫龙数字一体化电子白板”将计算机主机、音箱、功放、中央控制系统、操作面板、电子白板等设备设计在一起，形成一个运输、安装、调试、使用都更简单的数字一体化电子白板整体设备。数字一体化电子白板“班班通”建设在教室以数字一体化电子白板为基础，依据TCP/IP协议标准，采用星型或多级星型结构，以计算机网络技术、计算机控制技术、综合视音频编码技术及流媒体技术为基础，进行“班班通”整体技术设计；将多媒体教学、智能校园广播、数字校园电视、设备管理、班务管理等功能模块化实现。2方案特色点数字一体化电子白板“班班通”建设以各个教室的信息化建设为核心，在每个班通如下内容：天网——远程教育Ku波段通到每间教室；地网——宽带或局域网通到每间教室；数字电视网——有线电视或卫星电视通到每间教室；数字广播网——校园数字广播通到每间教室；视频会议网——全校大会、电化教学通过视频会议方式进入每间教室；人网――老师随身携带的U盘、移动硬盘等教学资源能在教室中直接使用。电子白板和配套设备一体化设计，由原来的以写为主提升到自带电脑、功放、音箱、中央控制系统等。使用更方便。自带中控系统，白板、投影机、主机的开启关闭不需要一个一个操作，可以通过控制系统一键完成。免除70％工程量，安装方便。可使用滑轨、支架等不同方式安装在高压缸排汽的总管上装有动力控制止回阀，以便在事故情况下切断，防止蒸汽返回到汽轮机，引起汽轮机超速。在高压缸排汽总管的端头有蒸汽冲洗接口，以供在管道安装完毕后进行冲洗，在管道冲洗完成后用堵头堵死。centerpinchecksandanchoringtheinnercylinder.AccordingtoWhilecouplingalignmentshouldkeepoiloutofcavityandlocatetherotoraxisneckraisedarewithintheprescribedlimits,thereshouldbenogaps,Horn,HornandHorn0.05mmfeelergaugesfitinto.Centercoupling,condenserwaterfillingandwater-filledaccordingtofactoryrequirement.ForcouplingthreesupportedrotorCenter,themouthunderthecouplingbetweenthevalueshouldbeasstipulatedinthemanufacturer,usually0.15~0.25mm.Inthecaseofcouplingconnection,ifpossible,liftingonlyonebearingendofthesupportbearingoftherotor,removethebearing,fittedwithspecialtilesandspecialliftingtools,discrotors,checkthejournalfluttertile,shouldgenerallybelessthan0.10MM.Whenthecouplingsandrotorcomeswhenthereisaconflict,thecouplingCentreshallprevail.6.4.5.2.2shaftlookingfor:...6.4.5.3.Provisionalboltconfirmedthepositioningoftherotorsize,aswellasthecouplingbetweentheadjustmentshimthicknessaccuracy,drawingstomeetthetechnicalrequirements.Plane,cylindricalandcleanthecouplingboltholesshouldbecleanandwithoutburrs,scrapironandgrease-free,relativepositionofthecouplingaccordingtothedrawingrequirementsare.Couplingtopscrews,rounddistanceapart,indicatorstomonitormovementoftheaircraft,itsvalueisallowedtopassthevalueaxismoving,mountedadjustmentpads,notepadsinstallationdirectionguidepincouplingwithprocessendclosed.Thebackwheelsslowlytightened,when2mmorso,withstandardwhitebarswheretwobackwheelboltholemeasurementaboveandbelow,confirmtwobackwheelboltholeconcentricity.Then,thesymmetricalhorizontalmounttwotemporaryboltstightened,attentiontomonitordialindicator,theninstallthesymmetricaltemporarybolts,thistimesitesslowlymovingrotor,inthemeasuredcircumferenceof8equalpartsbackwheelrimrock,eachmeasuringrelativechangesinvalueshouldbelessthan0.02mm.6.4.5.4couplingreamedandpairedboltreamingdiereamer,adjustablereamers,boringmill,inseveralways.6.4.5.4.1Generalrequirementsbeforereamingorboring,免除70％维护量操作简单，支持无线鼠标键盘，可选配遥控器不再单机运行，可形成网络，整体管理、整体运行、整体维护。接口丰富。可接入笔记本电脑，可接入实物展台，支持接入无线麦克风。3功能模块积木式“班班通”建设系统全面的技术功能包括如下四大功能模块：在高压缸排汽的总管上装有动力控制止回阀，以便在事故情况下切断，防止蒸汽返回到汽轮机，引起汽轮机超速。在高压缸排汽总管的端头有蒸汽冲洗接口，以供在管道安装完毕后进行冲洗，在管道冲洗完成后用堵头堵死。centerpinchecksandanchoringtheinnercylinder.AccordingtoWhilecouplingalignmentshouldkeepoiloutofcavityandlocatetherotoraxisneckraisedarewithintheprescribedlimits,thereshouldbenogaps,Horn,HornandHorn0.05mmfeelergaugesfitinto.Centercoupling,condenserwaterfillingandwater-filledaccordingtofactoryrequirement.ForcouplingthreesupportedrotorCenter,themouthunderthecouplingbetweenthevalueshouldbeasstipulatedinthemanufacturer,usually0.15~0.25mm.Inthecaseofcouplingconnection,ifpossible,liftingonlyonebearingendofthesupportbearingoftherotor,removethebearing,fittedwithspecialtilesandspecialliftingtools,discrotors,checkthejournalfluttertile,shouldgenerallybelessthan0.10MM.Whenthecouplingsandrotorcomeswhenthereisaconflict,thecouplingCentreshallprevail.6.4.5.2.2shaftlookingfor:...6.4.5.3.Provisionalboltconfirmedthepositioningoftherotorsize,aswellasthecouplingbetweentheadjustmentshimthicknessaccuracy,drawingstomeetthetechnicalrequirements.Plane,cylindricalandcleanthecouplingboltholesshouldbecleanandwithoutburrs,scrapironandgrease-free,relativepositionofthecouplingaccordingtothedrawingrequirementsare.Couplingtopscrews,rounddistanceapart,indicatorstomonitormovementoftheaircraft,itsvalueisallowedtopassthevalueaxismoving,mountedadjustmentpads,notepadsinstallationdirectionguidepincouplingwithprocessendclosed.Thebackwheelsslowlytightened,when2mmorso,withstandardwhitebarswheretwobackwheelboltholemeasurementaboveandbelow,confirmtwobackwheelboltholeconcentricity.Then,thesymmetricalhorizontalmounttwotemporaryboltstightened,attentiontomonitordialindicator,theninstallthesymmetricaltemporarybolts,thistimesitesslowlymovingrotor,inthemeasuredcircumferenceof8equalpartsbackwheelrimrock,eachmeasuringrelativechangesinvalueshouldbelessthan0.02mm.6.4.5.4couplingreamedandpairedboltreamingdiereamer,adjustablereamers,boringmill,inseveralways.6.4.5.4.1Generalrequirementsbeforereamingorboring,4系统网络拓扑结构图如下：5主控室主控系统5.1主控室建设概述常用主控室设备有：管理、控制服务器，资源服务器，数字广播电视台三部分。主控室的建设原则如下：建议学校采用数字广播电视系统多网合一的建设方式，这种方式可以使系统造价降低30％以上，稳定性提高70％以上，维护工作量降低70％以上。建议在建设“班班通”主控室时将主控室工程施工标准化，用标准机柜安装，这样系统具有一体化
