0摘要庆阳石化公司提出建设生产调度和应急通信的的通信系统的要求，由于集群通信系统是一种高级移动调度系统，代表着通信体制之一的专用移动通信网发展方向。所以采用了无线集群对讲系统方案来满足其生产调度和应急通信的要求。首先，按照集群通信方案考察现场筛选出基站站址备用地，再按照规定从候选地中确定基站最终站址；其次，按照覆盖范围设计无线集群系统铁塔和天线敷设，基站用户量确定信道数；最后，做出基站并按照在特殊行业对无线集群对讲系统设备要求，完成相关设备选型；所设计出的无线集群对讲系统所具有的功能能够满足庆阳石化日常生产调度，同时能够满足应急通信的要求。关键字：信道；对讲机；移动台；基站；无线集群系统1AbstractQingyangPetrochemicalcompaniestobuildthecommunicationsystemrequirementsofproductionschedulingandemergencycommunication,astrunkingcommunicationsystemisanadvancedmobiledispatchsystem,representsoneoftheprivatemobilecommunicationsystem,communicationnetworkdevelopment.Sousingawirelessintercomsystemclustersolutiontomeettheirproductionschedulingandemergencycommunicationrequirements.First,inaccordancewiththetrunkingcommunicationprogramstudysiteselectedbasestationcandidatesites,theninaccordancewithregulationsfromthecandidatetotheidentifiedbaseendstationsite;Secondly,inaccordancewiththecoverageofthedesignofthewirelessclustertowerandantennainstallation,subscribersofbasestationstodeterminenumberofchannels;Finally,designabasestationandthewirelessindustry,accordingtoclusterinparticularintercomsystemequipmentrequiredtocompletetherelatedequipmentselection;thedesignofwirelessintercomsystemshaveaclusteroffeaturestomeetthedailyproductionschedulingofQingyangPetrochemical,andalsotomeetemergencycommunicationsrequirements.Keywords:channel;radio;mobilestations;basestations;wirelesscluster2目录第1章绪论........................................................................................................................................41.1集群通信系统.......................................................................................................................41.2无线集群的基本概念...........................................................................................................41.3无线集群通信原理...............................................................................................................41.4集群通信的工作过程...........................................................................................................51.5移动台对讲机原理介绍.......................................................................................................61.6集群对讲系统.......................................................................................................................6第2章庆阳石化无线通信系统方案................................................................................................72.1庆阳石化的实际无线通信方案要求...................................................................................72.1.1庆阳石化的无线通信系统需求................................................................................72.1.2无线通信系统的功能设计要求................................................................................82.1.3无线通信系统的技术要求........................................................................................82.2无线集群对讲系统方案的提出...........................................................................................92.2.1无线通信系统的选型................................................................................................92.2.3无线集群对讲系统的功能设计..............................................................................11第3章庆阳石化无线集群对讲系统方案设计..............................................................................153.1庆阳石化系统技术指标设计.............................................................................................153.2庆阳石化无线集群对讲系统方案设计.............................................................................163.2.1庆阳石化无线对讲系统覆盖选址..........................................................................163.2.2系统用户容量设计..................................................................................................173.2.3天线覆盖预算..........................................................................................................173.2.1庆阳石化无线对讲系统覆盖方案..........................................................................173.2.4集群铁塔设计..........................................................................................................183.2.5铁塔天线安装设计..................................................................................................193.3庆阳石化集群系统其他辅助设计.....................................................................................203.3.1电源..........................................................................................................................203.3.2温度、湿度..............................................................................................................203.3.3接地..........................................................................................................................203.3.4安装机房的场地设计..............................................................................................203.4庆阳石化集群系统主要性能参数设计.............................................................................2133.4.1信道机设计..............................................................................................................213.4.2合路器/分路器设计................................................................................................223.4.
