摘要:
贵广客运专线改造后在 CTCS-3 级列控区段采用同址双基站冗余覆盖方案,通过对该组网方案工作原理进行分析,提出 A 网和 B 网基站功率、切换参数、邻区关系等参数设置建议,同时分析直放站区段存在快衰隐患,提出从信号思路,并对从信号设置、规划方案进行研究,选取一个基站的从信号进行模拟验证测试,结果表明引入从信号能够达到良好效果,研究结果对新铁路建设或既有铁路改造冗余覆盖的设计提供了新的思路。
Abstract:
Following the renovation of the Guiyang-Guangzhou Passenger Dedicated Line, a redundant coverage scheme with co-located dual-base stations in the area of train operation control with CTCS-3 is adopted. By analyzing the working principle of this networking scheme, recommendations are proposed for parameter settings such as base station power, handover parameters, and neighbor cell relationships for both Network A and Network B. Additionally, the potential risk of rapid fading in repeater sections is analyzed, prompting a focus on signal design. Research is conducted on signal settings and planning schemes, with a slave signal from one base station selected for simulation and verification testing. The results indicate that the introduction of the slave signal achieves satisfactory outcomes. The findings of this study provide new insights into the design of redundant coverage for the construction of new lines or the reconstruction of existing lines.
