Internet of things-based roadbed monitoring and early warning system

Abstract

The invention discloses a roadbed monitoring and early warning system based on the Internet of Things, comprising: a geographic coordinate position collection device, a data collection device, a data processing platform, and a monitoring and early warning platform; the geographic coordinate position collection device collects the geographic location coordinates of the currently monitored roadbed; data The acquisition device collects the initial information data of the roadbed and the deformation information data of the roadbed at the monitoring position; the data processing platform receives the geographical location coordinates, the initial information data of the roadbed and the deformation information data of the roadbed through the wireless module, and The information data and subgrade design data information data obtain the subgrade deformation data and the subgrade deformation curve at the monitoring position; the monitoring and early warning platform monitors the current monitoring subgrade according to the subgrade deformation data and subgrade deformation curve and outputs judgment results, and the monitoring and early warning platform based on the judgment results Output or not output early warning signal.

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
