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.
