管一霖, 杨万辉, 包静. Research on fault maintenance strategy of indoor coverage system based on intelligent composite feeder[J]. 2018, 31(2): 60-63. DOI: 10.13992/j.cnki.tetas.2018.02.019.
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 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.
