Abstract

The ominbearing visual debris flow pre warning alarm device comprises rain fall inspection unit, debris flow generation inspection unit, rain fall intensity computation unit, debris flow relative hydrometeorology historical record memory unit, debris flow pre warning unit, statistical pre warning module, and debris flow pre warning information release unit, with 10 minutes rain intensity, one hour rain intensity, efficient rain fall as the entry, judging the debris flow occurrence probability under the condition through statistical pre warning alarm module and seriousness and severity of the disaster, releasing the result to residents of the downstream disaster risk area, to take beforehand precaution to avoid loss and damage to debris flow.

Description

(1) Technical field [0001] The invention belongs to the application of all-round visual sensing technology, computer image processing technology, multimedia technology, network communication technology, debris flow ground sound detection technology, surface activity observation technology when geological disasters occur, and rainfall visualization technology in geological disaster prediction and early warning It is mainly suitable for mountainous areas and river monitoring where geological disasters such as mudslides occur frequently, so as to reduce the loss of life and property of local people. In particular, a debris flow early warning and forecasting device. (2) Background technology [0002] Debris flow is a solid-liquid two-phase fluid filled with a large amount of sand, stones and boulders. It is in the state of viscous laminar flow or dilute turbulent flow, and is the result of the combined effects of various natural factors (geology, landform, hydrology, meteorolog...
