The invention discloses a tunnel health monitoring system based on distributed sensing optical fiber, which relates to the technical field of tunnel health monitoring. It includes background monitoring center subsystem, communication network module, online monitoring system installed in the tunnel and early warning module. The background monitoring center subsystem is used for real-time monitoring of the health status inside the tunnel in the coverage area of the system in the background monitoring room, and the communication network module provides communication support for the background monitoring center subsystem and the online monitoring system. The online monitoring system is used for monitoring the health inside the tunnel within the coverage area of the system, and the early warning module is used for early warning inside the tunnel. The invention adopts two methods of distributed sensing optical fiber and wireless data transmission, which ensures the agility of information data transmission in normal use and the safety of normal communication when tunnel accidents occur, and it can give early warning of accidents in time.
