Earthquake-induced secondary landslide post-disaster evaluation and rescue auxiliary system

Abstract

The invention discloses an earthquake-induced secondary landslide post-disaster evaluation and rescue auxiliary system, which comprises a special detection unmanned aerial vehicle building module forbuilding a special post-earthquake landslide disaster detection and recognition unmanned aerial vehicle, and a post-earthquake landslide detection planning preparation module for completing various preparation works before disaster detection and recognition, apost-earthquake environment information acquisition module used for acquiring on-site landslide disaster images and position information coordinates, a Beidou navigation positioning module used for assisting above three modules in the aspects of navigation system construction, cruise route setting and information acquisition and transmission; a landslide disaster analysis decision module used for analyzing related attribute parameters such as post-earthquake secondary landslide disaster influence area, trailing edge height and stability, and a post-earthquake rescue planning evaluation module used for planning a rescue route, making a rescue scheme and evaluating the disaster influence degree. According to the invention, the accuracy, the real-time performance and the high efficiency in intelligent identification function requirements of post-earthquake secondary landslide disasters can be met.

Description

technical field [0001] The invention belongs to the field of intelligent disaster relief, and in particular relates to a post-disaster assessment and rescue auxiliary system for secondary landslides induced by earthquakes. Background technique [0002] Earthquake secondary landslide hazards are large-scale landslides caused by earthquakes, which can occur immediately with the earthquake or within a period of time after the earthquake. Earthquake secondary landslides are not only large in scale, but also have the characteristics of high sliding speed, long sliding distance and wide disaster area. Earthquake-induced landslide disasters are very serious, and sometimes the losses caused by secondary landslide disasters are greater than those directly caused by earthquakes. my country has a vast land area and many mountains. Due to differences in geological structure and other reasons in different regions, the performance of secondary landslides induced by earthquakes is also ve...

Problems solved by technology

This approach lacks responsiveness when encountering some emergencies. For example, the rescue route is blocked by a secondary landslide disaster. Temporarily changing the rescue route will greatly consume the rescue time; when entering the disaster site for investigation and formulation of a rescue plan, it is easy to The occurrence of secondary landslides caused more casualties; when using drones to scout on-site conditions, video streams or manual observation of camera images are often used to screen landslide scenes in disaster areas. This method consumes manpower and material resources and cannot achieve intelligent detection. and locate rescue needs
