PAGE \* MERGEFORMAT 1 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  Abstract Qingyang Petrochemical companies to build the communication system requirements of production scheduling and emergency communication, as trunking communication system is an advanced mobile dispatch system, represents one of the private mobile communication system, communication network development. So using a wireless intercom system cluster solution to meet their production scheduling and emergency communication requirements. First, in accordance with the trunking communication program study site selected base station candidate sites, then in accordance with regulations from the candidate to the identified base end station site; Secondly, in accordance with the coverage of the design of the wireless cluster tower and antenna installation, subscribers of base stations to determine number of channels; Finally, design a base station and the wireless industry, according to cluster in particular intercom system equipment required to complete the related equipment selection; the design of wireless intercom systems have a cluster of features to meet the daily production scheduling of Qingyang Petrochemical, and also to meet emergency communications requirements. Key words: channel; radio ; mobile stations; base stations; wireless cluster  目　录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc264194331 第1章 绪论 PAGEREF _Toc264194331 \h 4 HYPERLINK \l _Toc264194332 1.1 集群通信系统 PAGEREF _Toc264194332 \h 4 HYPERLINK \l _Toc264194333 1.2 无线集群的基本概念 PAGEREF _Toc264194333 \h 4 HYPERLINK \l _Toc264194334 1.3 无线集群通信原理 PAGEREF _Toc264194334 \h 4 HYPERLINK \l _Toc264194335 1.4 集群通信的工作过程 PAGEREF _Toc264194335 \h 5 HYPERLINK \l _Toc264194336 1.5 移动台对讲机原理介绍 PA
