摘　　要：城市轨道交通专用无线集群系统采用宽带集群制式LTE-M(城市轨道交通用长期演进)取代TETRA(泛欧集群无线电)集群通信已成为行业共识。在窄带集群向宽带集群改造的过程中,调度终端和车载终端的改造将直接影响列车运行的安全。对比了双模调度、双模车载台及宽窄带互联互通3种过渡方案的优缺点,并结合改造的前期、中期、后期及运营后4个阶段对其风险进行评估。推荐采用双模调度和双模车载台相结合的方式,该方式在改造过程中对运营线路的影响最小。It has become an industry consensus that the broadband trunking system adopts LTE-M instead of TETRA trunking communication.During the process of transforming from narrowband trunking to broadband trunking,the transformation of dispatching terminals and train-borne terminals directly affects the safety of train dispatching.By comparing the advantages and disadvantages of three schemes:dual-mode dispatching,dual-mode train-borne radio unit and broadband and narrowband interoperation,and evaluating the risks in combination with the four stages of transformation:before,during,after and after fully operational.It is recommended to adopt the combination of dual-mode dispatching and dual-mode train-borne radio unit for smooth transition,with the least impact on the operating line in the transformation process.
