Tunnel service safety intelligent monitoring and early warning system

The utility model provides an intelligent monitoring and early warning system for tunnel service safety. The intelligent monitoring and early warning system comprises a Beidou displacement monitoring system, an inclinometer, a laser convergence meter, a crack meter, a strain meter and a data acquisition box, the Beidou displacement monitoring system and the rain gauge are arranged at typical positions selected from a tunnel side upward slope, the inclinometer is arranged at a typical position selected from a tunnel portal end wall, and the laser convergence gauge, the strain gauge and the temperature, humidity, illumination and gas integrated monitor are all arranged at a typical section in a tunnel hole. According to the utility model, through modern monitoring means, spatial positions, mechanical properties and related dynamic changes of key parts of the tunnel are monitored and analyzed, thereby intelligently sensing the service state of the tunnel structure, dynamically mastering the technical condition a
