Abstract: Aiming at the problems of inflexible wired networking, limited monitoring capabilities, and insufficient linkage functions of the current railway tunnel disaster prevention and rescue monitoring system, combined with the advantages of 5G technology and its application prospects in railways, this paper proposes a new 5G-based scheme system. Its compatibility considering the two carrying modes of railway 5G private network and public network, the compatibility system architecture of the two is designed, and the system deployment scheme of the two is analyzed. This system has the ability of flexible networking, expansion and upgrading, and the integration of cutting-edge technical, which means that it is able to realize functions such as early warning and alarm, linkage control, one-key rescue, simulation presentation and so on, so as to realize intelligent operation and maintenance management, additionally to improve the ability of railway tunnel disaster prevention and rescue.
