Abstract

The invention provides a displacement-based rainfall landslide early-warning method and a displacement-based rainfall landslide early-warning device. The method comprises the steps of obtaining current rainfall intensity of a side slope and current displacement of a target monitoring point; when the current rainfall intensity is greater than target rainfall intensity, judging whether the displacement of the target monitoring point is greater than a target displacement threshold or not; and when the displacement of the target monitoring point is greater than the target displacement threshold, releasing early-warning information. Thus, through implementation of the displacement-based rainfall landslide early-warning method and device, the rainfall landslide can be early warned accurately by combining the rainfall intensity and the displacement of the target monitoring point.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a displacement-based rainfall-type landslide early warning method and device. Background technique [0002] my country is a country with frequent landslides. Landslides destroy infrastructure and have a serious impact on national modernization and people's lives. Every year, a considerable number of cities and villages in the country suffer from landslides, causing countless economic losses every year. According to statistics, about 90% of landslides are related to rainfall. How to use rainfall information as a landslide-inducing factor for early warning has become an urgent problem to be solved. [0003] The prior art also has an early warning scheme for rainfall-type landslides. They only analyze the stability of the slope with one rainfall intensity, and then carry out early warning according to the analysis results. [0004] It should be pointed out that it is one-side...
