计算机联锁工程设计

兰州交通大学毕业设计（论文）-I-摘要计算机联锁系统是继6502电气集中系统的又一种联锁系统，它保证了工作的可靠，是保证行车安全的信号基础设备，符合“故障—安全”的原则。计算机联锁目前是最先进的车站联锁设备，我国的计算机联锁都是从继电电气集中过渡发展起来的。本次设计为电化区段兰成线34号站下行咽喉计算机联锁工程设计，设计的主要内容包括：34号站下行咽喉的车站信号平面布置图、下行咽喉联锁表、双线轨道电路布置图、电缆网络图、电缆径路图、计算机联锁系统结构图、组合排列表、组合类型表、室内设备布置图、工程数量统计表。其中车站信号平面布置图可以直观的反映室外设备的布置情况，主要有信号机、道岔、警冲标的布置、编号与位置的计算。联锁表包括方向、进路、按钮、信号机、道岔、敌对信号和轨道区段的选择与确定等。双线轨道电路图主要完成的是送受电端的设置、扼流变压器的布置、轨道电路极性交叉的配置。电缆网络图和径路图中主要是电缆的合理敷设、电缆长度的计算、芯数的计算等，是施工挖沟的主要依据。计算机联锁系统结构图可以反映出所采用的双机热备系统的硬件构成以及它的工作原理。组合排列表中反映了信号柜、轨道柜、道岔柜的排列情况与组成。组合类型表包含了各种组合所包含的继电器名称和类型。室内设备平面布置图包括信号电源室、防雷分线室、机械室、控制台室，计算机房内各种设备的布置。工程数量统计表统计的是34号站下行咽喉所需要的所有电缆线、信号机、盒子、柜子、道岔、轨道、继电器等的数量。关键词：计算机联锁；工程设计；联锁表；极性交叉；继电器兰州交通大学毕业设计（论文）-II-AbstractComputerinterlockingsystemisfollowingthe6502Electricsystemyetanotherinterlockingsystem,whichguaranteesreliableworkistoensuretrafficsafetysignalinfrastructure,inlinewithfail-safeprinciple.Interlockingiscurrentlythemostadvancedcomputerstationinterlockingequipment,China'stransitionfromacentralizedcomputerinterlockingrelaysareelectricallydeveloped.Thedesignofelectro-chemicalsectorintolineNo.34Portlandstationdownstreamofthethroatcomputerinterlockingengineeringdesign,designofthemaincontentsinclude:No.34stationdownstreamofthethroatofthestationsignalfloorplan,downstreamofthethroatinterlockingtable,doubletrackcircuitlayout,cablenetworkdiagrams,cableroutemaps,computerinterlockingsystemstructurediagram,alistrowcombination,thecombinationofthetypeoftable,interiorequipmentlayout,engineeringandquantitystatistics.Stationsignalfloorplanwhichcanreflecttheintuitivearrangementofoutdoorequipment,themainsignal,turnout,policerushedtheunderlyinglayout,calculatingnumbersandlocations.Interlockingtableincludesdirection,intotheroad,buttons,signal,switch,hostilesignalsandtracksectionstodeterminetheselectionandsoon.Doubletrackcircuitdiagramismainlydonebysendingelectricalterminalsettings,layoutchoketransformer,polaritycrosstrackcircuitconfiguration.FIGFIGcablenetworkandthemainpathwayisreasonablelayingcablelengthcalculation,calculationofthenumberofcablecores,ismainlybasedontheconstructionoftrench.Computerinterlockingsystemstructurereflectsthehardwareconfigurationhotstandbysystemusedandhowitworks.Listreflectsacombinationofrowarrangementofthesignalcabinet,trackcabinets,countersandcompositionoftheturnout.CombinationTypetablecontainsthenamesandtypesofvariouscombinationsofrelaysincluded.Indoorequipmentlayoutplanincludingroomlayoutsignalpower,lightning-pointlineroom,mechanicalroom,theconsoleroom,computerroomvariousdevices.Quantityisthenumberofstatisticaltablesworksall34cablestationsdownstreamofthethroatneeded,signalboxes,cabinets,switches,track,relays,etc.KeyWords:ComputerInterlocking,EngineeringDesign,InterlockingTable,Polarcross,Relay兰州交通大学毕业设计（论文）-III-目录摘要.....................................................................................................................................IAbstract.....................................................................................................................................II1绪论........................................................................................................................................11.1设计的主要技术标准..................................................................................................11.2设计的研究现状.........................................................................................................11.3设计的主要内容.........................................................................................................12车站信号平面布置图............................................................................................................22.1信号机的设置.............................................................................................................22.1.1进站信号机......................................................................................................22.1.2出站信号机......................................................................................................22.1.3调车信号机......................................................................................................32.2转辙机的设置.............................................................................................................32.3绝缘节的设置.............................................................................................................32.4坐标计算.....................................................................................................................42.4.1道岔的坐标......................................................................................................42.4.2警冲标的坐标..................................................................................................42.4.3信号机的坐标..................................................................................................42.4.4绝缘节的坐标..................................................................................................42.4.5股道有效长度的计算......................................................................................43联锁表的编制..........
