Safety management and control system for long tunnel group engineering lines integrated with Beidou positioning technology
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.
