Abstract: This paper addressed the issue of high safety risks in the construction of railway long tunnel group engineering lines, by integrating Beidou satellite navigation system positioning technology, designed and implemented a safety management and control system for long tunnel group engineering lines. The paper used Beidou positioning technology and a comprehensive networking technology of "ultra wideband communication+long-distance radio+wireless access point" to establish communication networks inside and outside the long tunnel group, implemented real-time positioning and remote scheduling of power vehicles and operators, vehicle approach warning, and other functions. It has been applied online on the Emei-Mianning section of the Chengdu-Kunming Railway. The application results show that the system can effectively reduce the construction safety risks of long tunnel groups.
