High-precision Tunnel Positioning System
Yiri and CRCC 14th Bureau jointly set up a tunnel personnel and vehicle positioning system in one tunnel of Yichang-Badong Highway.
The system integrates the personnel attendance management, emergency evacuation, SOS emergency assistance, real-time monitoring, trajectory tracking, trajectory playback and other functions, and has the advantages of “low cost and high efficiency”, enabling monitoring personnel to get real-time personnel information of the tunnel and realizing the scientific management. In addition, information on each area of the tunnel can be quickly reported at any time, thus providing the timely information for accident or event handling and greatly improving the working efficiency.
The high-precision tunnel positioning system solves the problems of the lack of reliable location information and corresponding voice communication means, as well as low efficiency in safe rescue in emergencies in the tunnel.
