摘　　要：为满足城市轨道交通无线通信系统共线运营需求,从政策、线路特点、运营模式、建设时序等角度,对影响无线通信系统实现共线运营的因素进行分析。以实现大连地铁1号线和5号线共线运营为例,通过分析既有不同无线通信技术制式的实际情况,提出采用TETRA、LTE-M和改变运营模式3种方案,并从技术可行性、运营难度和建设成本等方面,进行深入剖析,进而总结出适用于不同城市的无线通信系统共线运营研究方法。通过对比论证得出:在两线采用不同通信技术制式的情况下,宜采用满足互联互通需求的LTE-M作为共线运营的技术制式;在新建线采用LTE-M、既有线路实施大修改造前,两线通过设置双车载、双地面设备满足无线通信系统共线运营的需求;在新建线采用LTE-M、既有线路实施大修改造后,两线通过实现LTE中心设备的互联互通,满足无线通信系统共线运营需求。本研究结果为两线在不同技术制式下实现无线通信系统共线运营提供了建设方案和研究方法。In order to meet the requirements of co-line operation of wireless communication system in urban rail transit,the factors affecting the co-line operation of wireless communication system are analyzed from the perspectives of policy,line characteristics,operation mode and construction sequence.Taking the co-line operation of Dalian Metro Line 1 and Line 5 as an example,based on the analysis of the actual situation of adopting different wireless communication technology standards in existing lines,three schemes,namely TETRA,LTE-M and changing operation mode,are put forward,and deeply discussed from the aspects of technical feasibility,operation difficulty and construction cost,and then study methods for co-line operation of wireless communication systems suitable for different cities are proposed.Based on comparison and demonstration,it is concluded that under the condition that the two lines adopt different communication technology standards,LTE-M supporting interconnection should be adopted as the technical standard of co-line operation;before the new line adopts LTE-M and the existing line is overhauled and reconstructed,the two lines meet the requirements of co-line operation of wireless communication system with the aid of dual onboard and dual ground devices;after LTE-M is adopted in the new line and the existing line is overhauled and reconstructed,the two lines meet the requirements of co-line operation of wireless communication system with the aid of the interconnection of LTE central equipment.The results present a construction scheme and a study method for realizing the co-line operation of wireless communication system under different technical standards.
