Landslide and debris flow monitoring and early warning method, equipment, system and medium

Abstract

The invention discloses a landslide and debris flow monitoring and early warning method, device and system and a medium, and the early warning method comprises the following steps: obtaining real-time monitoring data of a monitoring area, the real-time monitoring data comprising landform data and sound wave data; performing feature extraction on sound wave data in the real-time monitoring data to obtain a real-time feature value group; comparing the real-time characteristic value group with a characteristic value group corresponding to historical sound wave data collected when no debris flow occurs in the monitoring area to obtain sound wave similarity; fusing the landform data in the real-time monitoring data and the landform data collected when the debris flow does not occur in the monitoring area in a simulation 3D landform map, and calculating the landform data difference; when the sound wave similarity is smaller than a first preset threshold value and / or the landform data difference is larger than a second preset threshold value, early warning information is generated. Meanwhile, early warning is realized based on the landform data and the sound wave data, the misjudgment rate can be reduced, and the early warning accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of landslide monitoring, and in particular relates to a landslide debris flow monitoring and early warning method, equipment, system and medium. Background technique [0002] Debris flow refers to landslides caused by heavy rain or other natural disasters in the mountains or other areas with steep terrain and carries a large amount of sediment and torrents. It is characterized by suddenness, fast flow, large flow, and strong destructive power. The destruction of transportation facilities such as roads and railways, flooding of villages and towns, etc., caused huge losses. [0003] Debris flow disasters generally occur suddenly, the precursor phenomenon is not obvious, and the sudden debris flow disaster activity is strong. Therefore, it is difficult to predict and prevent it, resulting in huge losses. In the existing technology, there are low precision and low efficiency in the monitoring and identification ...

Problems solved by technology

[0003] Debris flow disasters generally occur suddenly, the precursor phenomenon is not obvious, and the sudden debris flow disaster activity is strong. Therefore, it is difficult to predict and prevent it, resulting in huge losses. In the existing technology, there are low precision and low efficiency in the monitoring and identification of debris flow disasters. And the problem of slow response to early warning, therefore, it is urgent to provide a system and method for monitoring and early warning of debris flow, so as to avoid the loss caused by debris flow
