摘　　要：广西国际壮医医院出现室分疑难故障,初步的排查工作一度陷入困境。通过分析成因,有针对性地核查数据,检查宏站,调整参数,做对比测试,轮流堵直放站,分段排查天馈和设备,对该疑难故障进行深入研究,最终定位出POI故障是导致该疑难故障的主要原因。此外,通过进一步的研究可以获知,以RRU替换直放站可以提高室分稳定性,降低室分出现疑难故障的概率。上述排查方法是处理疑难室分故障的一种新思路。The indoor distribution system of Guangxi International Zhuang Medical Hospital has a difficult fault,and the preliminary troubleshooting was once in trouble.Later,through analyzing the causes,pertinently checking the data,inspecting the macro base station,adjusting parameters,doing comparative tests,blocking repeaters in turn,and using sectional troubleshooting method for the Antenna-feeder and the equipment,this paper researches the difficult fault deeply.Finally,it is determined that the POI fault is the main cause of thed ifficult fault.In addition,through further research,it can be known that replacing repeaters with RRU can enhance the stability of the indoor distribution system and reduce the probability of difficult faults.The above troubleshooting method is a new way to deal with difficult faults of indoor distribution systems.
