Satellite technology-based wide area geological disaster forecasting system and method

Abstract

The invention discloses geosynchronous satellite time-sharing data transmission technology and satellite navigation positioning technology-based wide area geological disaster forecasting system and method. The system comprises a space section and a earth section, wherein the space section consists of a geosynchronous time-sharing data transmission satellite (geostationary earth orbit, GEO) and a navigation positioning satellite (medium earth orbit-geostationary earth orbit, MEO-GEO); the earth section consists of a earth surface displacement sensor terminal array system, a earth signal gate station, and a geological disaster monitoring center; the geological disaster monitoring center analyze the earth surface displacement distribution situation according to the information acquired by the earth surface displacement sensor terminal array system and sent by the geosynchronous time-sharing data transmission satellite and the navigation positioning satellite, analyzes and discovers the regions possibly having geological disaster dangers by utilizing an earth surface displacement-geological disaster trend mathematical model established in advance, and sending a caution command to all regions in the interior of the motoring center in time so as to ensure enough response time before the geological disaster occurs, thus loss of national life and property is avoided.

Description

technical field [0001] The invention relates to a wide-area geological disaster forecasting system and method, in particular to a wide-area geological disaster forecasting system and method based on satellite technology. Background technique [0002] At present, the early warning and forecasting system of geological disasters in a wide area is mainly for the relative movement of the surface due to the release of terrain energy after the precipitation reaches the saturation level of the ground soil to absorb water, and the occurrence of debris flows, landslides, etc. is harmful to human life and property. Accident early warning for geological disasters causing hazards. At present, the acquisition of such geological disaster early warning data generally relies on weather forecasting, precipitation measurement, manual on-duty, manual inspection of displacement areas, etc., in a localized, small-scale, and data-lag manner. Existing forecast methods need to arrange a large numbe...

AI Technical Summary

Problems solved by technology

The surface displacement sensor is greatly affected by the environment, insufficient sampling of the surface displacement data, small data transmission range, unstable monitoring system, etc.

At present, there is no method for comprehensive collection of surface displacement data in wide-area areas and a monitoring system for stable and effective early warning and forecasting of geological disasters
