摘要
南京地铁2号线无线集群系统异常,查找原因是天馈系统的四功分器故障导致信号覆盖异常。结合运营实际,从节约成本和提高可靠性方面提出解决方案,有效降低了天馈系统四功分器的故障率。
Abnormality occurs to the trunking radio system of Nanjing Metro line 2. The reason was found that the failure of the quad power divider in the antenna feed system led to abnormal signal coverage. So, a solution is proposed in term of low cost and high reliability in combination with actual operation practices.
