Embodiment Construction

[0117] The present invention will be further described below in conjunction with the accompanying drawings.

[0118] refer to Figure 1 to Figure 11 , a debris flow early warning and forecasting device based on omnidirectional vision, including an omnidirectional visual sensor for monitoring the water level of the mountain to be measured and the raincollection device, a raincollection device and a microprocessor for disaster detection based on video signals, said The omnidirectional vision sensor is installed above the ditch bed of the mountain to be measured, the output of the omnidirectional vision sensor is connected to the microprocessor, and the omnidirectional vision sensor includes an outer convex refracting mirror for reflecting objects in the monitoring field 1. A black cone 2 for preventing light refraction and light saturation, a transparent cylinder 3 and a camera 5, the outer convex catadioptric mirror surface 1 is located above the transparent cylinder 3, the out...

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...
