摘要
为确保高速列车的行车安全,铁路系统要求全线信号无缝覆盖,提出交织冗余备份直放站在GSM-R系统中的应用,系统组网到关键模块备份等两个层面,为信号无缝覆盖提供可靠性保障。首先介绍光纤直放站的工作原理,其次从系统组网和关键模块备份方面阐述系统的可靠性设计,最后讲述交织冗余备份光纤直放站的漏缆检测功能。
In order to ensure the safety of high-speed train operation, the railway system is required to cover the entire line with signals. The paper puts forward to use the interleaved redundancy backup repeaters and backup key modules in GSM-R system for ensuring signals seamless coverage. It also introduces the working principles of the fiber optic repeaters, the reliability design of the system and the detection function of leaky coaxial cables of the repeaters.
