Roadbed monitoring and early warning system based on Internet of Things

Abstract

The invention discloses a roadbed monitoring and early warning system based on the Internet of Things. The roadbed monitoring and early warning system comprises a geographic coordinate position acquisition device, a data acquisition device, a data processing platform and a monitoring and early warning platform. The geographical coordinate position acquisition device collects geographical positioncoordinates of a currently monitored roadbed. The data acquisition device collects initial roadbed information data and roadbed deformation information data of a monitored position. The data processing platform receives the geographic position coordinates, the initial roadbed information data and the roadbed deformation information data through a wireless module and acquires roadbed deformation data and a roadbed deformation curve of the monitored position according to the geographic position coordinates, the initial roadbed information data, the roadbed deformation information data and roadbed design data information data. The monitoring and early warning platform monitors the currently monitored roadbed according to the roadbed deformation data and the roadbed deformation curve and outputs a judgment result, and outputs or does not output an early warning signal according to the judgment result.

Description

technical field [0001] The invention relates to a roadbed monitoring and early warning system based on the Internet of Things, in particular to a roadbed monitoring and early warning system based on the Internet of Things that does not need to be pre-embedded before roadbed filling, has flexible settings and strong applicability. Background technique [0002] High-speed railway subgrade is used as the supporting foundation of the track, and post-construction settlement control of the subgrade is an important guarantee for track smoothness and long-term service performance. The existing subgrade construction adopts layered filling and placement to ensure that most of the subgrade settlement can be completed within the construction period, and minimize post-construction settlement after track laying. Post-construction settlement is an important cause of line irregularity and track structure damage, and the maintenance workload and cost of the line have increased significantly....

Problems solved by technology

The disadvantage is that the elevation error of the GPS satellite positioning system is relatively large, usually reaching more than 0.3m, which is difficult to meet the accuracy requirements of roadbed settlement monitoring
