Real-time monitoring and early warning system and method for high-speed train passing through inverted arch floating area in operation period

The invention provides a real-time monitoring and early warning system and method for a high-speed train passing through an inverted arch floating area in an operation period. The real-time monitoringand early warning system for the high-speed train passing through the inverted arch floating area in the operation period comprises a monitoring system and an early warning system, wherein the monitoring system comprises an information collection system, an information transmission system and an information processing system; the information collection system is used for collecting real-time dataof an inverted arch in a tunnel and three-dimensional state data of the tunnel inverted arch in the running process of a train and transmitting the data to the information processing system through the information transmission system; the information processing system is used for comparing the real-time data of the inverted arch in the tunnel with the original data of the inverted arch in the tunnel to identify the positi
