摘　　要：常规的轨道交通通信组网信道多设定为单层级,虽然可以完成预期的通信任务,但是传输结构不稳定,导致组网的吞吐量下降,通信效果较难控制。为此提出对城市轨道交通通信传输组网技术发展的研究与分析。综合组网设定的需求及标准,布设通信传输关联站点,设定多层级的组网传输信道,明确具体的轨道交通通信任务,完善传输结构,构建多层级传输信道,以此为基础,建立PDH组网传输模型,采用OCC集中控制实现组网设计。测试结果表明:设计的PDH交通通信传输组网技术测试组最终得出的吞吐量相对较高,表明组网在实际应用的过程中,交通通信传输速度快、范围广,误差可控,具有实际应用价值。Conventional rail transit communication networking channels are mostly set at single-layer level.Although they can complete the expected communication tasks,the transmission structure is unstable,resulting in a decline in the throughput of networking,and the communication effect is difficult to control.Therefore,the research and analysis on the development of urban rail transit communication transmission networking technology is proposed.According to the requirements and standards of networking setting,set communication transmission associated stations,set multi-level networking transmission channels,clarify specific rail transit communication tasks,improve transmission structure,and build multi-level transmission channels,through which PDH networking transmission model are established by using OCC centralized control to achieve networking design.The test results show that the final throughput of the PDH traffic communication transmission networking technology test group is relatively high,indicating that the traffic communication transmission speed is fast,the range is wide,and the error is controllable in the actual application process,which has practical application value.
