本文对目前移动通信中常用的天馈线模式和室内分布系统维护情况进行了分析,针对造成通信质量下降的重要因素：天馈线系统的维护问题进行探究,提出了基于智能复合天馈线远程供电传输模式下对室内分布系统的故障处理和维护方式,建立了新的故障监控和维护方式。在原有移动通信基站智能复合信号源和直流电源合路进天馈线远程传输供电系统的基础上通过增加室内分布天馈系统故障监测模块和功分器自动控制增益模块内置定向耦合器。并与天馈线驻波比或回损的值和隔离度及电压/电流标准数据库数学模型配合共同来实现室内分布系统天馈线的安装质量和网络运行情况的好坏判断。

Research on Fault Management and Maintenance Strategy of Indoor Coverage System Based on Intelligent Composite Feeder

This paper analyzes the maintenance mode of the antenna and the maintenance of the indoor distribution system, which is commonly used in mobile communication, and explores the maintenance of the feeder system. And puts forward the fault handling and maintenance mode of the indoor distribution system based on the intelligent composite antenna feeder remote power transmission mode, and establishes a new fault monitoring and maintenance mode based on the original mobile communication base station intelligent composite signal source (RF) and DC power (DC) combined into the antenna remote transmission power supply system based on the increase in indoor distribution antenna system fault monitoring module and power splitter automatic control gain module built-in orientation Coupler. Then we use VSWR or Return Loss of the antenna system or the voltage / current standard database mathematical model to achieve the indoor distribution system antenna installation quality and judgment of network operation of the situation.
