Title:
METHOD AND SYSTEM FOR REALIZING DISASTER EARLY WARNING BY MEANS OF DEFORMATION IDENTIFICATION OF RIVER CHANNEL LANDSLIDE
Document Type and Number:
WIPO Patent Application WO/2023/284344
Kind Code:
A1
Abstract:
A method and system for realizing disaster early warning by means of deformation identification of a river channel landslide. The method comprises: for the aspect of hardware arrangement, providing an array sensor at a monitoring point, wherein the sensor is internally composed of modules, a posture monitoring module collects coordinate, displacement and angle data, the data is subjected to DTU external transmission, and a solar power supply scheme is used; for the aspect of model construction, transforming the collected coordinate data and then performing surface fitting on same, in combination with the angle data, constructing a three-dimensional model of a landslide area, and dividing the three-dimensional model into a landslide area and a non-landslide area; and for the aspect of monitoring and early warning, predicting the displacement of the monitoring point in the landslide area by using a gray Verhulst model, and in combination with the three-dimensional model, realizing early warning and monitoring of the landslide area. The operation costs of a device are reduced, and same has low power consumption and is reliable; a three-dimensional model is divided into landslide and non-landslide areas, such that the real-time situation of a landslide body is visually understood; and a landslide trend at the next moment can be predicted by means of a gray Verhulst model, thereby achieving the combined effect monitoring and early warning.
