Inverted arch deformation monitoring and early warning system and method for high-speed rail tunnel in operation period

The invention discloses an inverted arch deformation monitoring and early warning system and method for a high-speed rail tunnel in an operation period. The system comprises an inverted arch deformation monitoring system and an early warning system; the inverted arch deformation monitoring system comprises a three-dimensional scanner used for scanning and monitoring the deformation of the invertedarch of the tunnel; the early warning system comprises a monitoring data analyzing and processing system and a railway early warning system; the three-dimensional scanner transmits inverted arch deformation monitoring data to the monitoring data analyzing and processing system through a signal transmission assembly; the monitoring data analyzing and processing system obtains an early warning level and transmits the early warning level to the railway early warning system; and the railway early warning system sends a deceleration or brake command to a corresponding train according to the earlywarning level. 本发明公开了一种用于高
