Debris flow monitoring and early warning system and method

Abstract

The invention provides a debris flow monitoring and early warning system and method, and the system comprises a target, a controller, and a camera, a multi-element weather collection module, a mountain fixed monitoring device, an acceleration sensor, a Beidou positioning module and a GPRS module which are electrically connected with the controller. The target and the mountain fixing and monitoring device are arranged in a debris flow channel of a monitoring area, the camera is arranged right opposite to the target, the mountain fixing and monitoring device is used for stabilizing a local slope and monitoring debris flow information, and the acceleration sensor is embedded in a boulder of the debris flow channel. The multi-element weather acquisition module is used for acquiring weather information, and the controller is in communication connection with a background server through the GPRS module. According to the debris flow monitoring and early warning system and method provided by the invention, early warning of debris flow disasters can be realized, the early warning accuracy is improved, protection and risk avoiding can be realized in time, and the harmfulness of debris flow is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of geological disaster monitoring, in particular to a debris flow monitoring and early warning system and method. Background technique [0002] Debris flow refers to a special torrent carrying a large amount of sediment and stones due to landslides caused by heavy rain, snowstorm or other natural disasters in mountainous areas or other areas with deep valleys and steep terrain. Due to the complex geological conditions, our country is a place where debris flow disasters frequently occur. Debris flow is a geological action between running water and landslides. A typical debris flow is composed of viscous mud with coarse solid debris suspended and rich in silt and clay. Under appropriate terrain conditions, a large amount of water soaks the solid accumulation in the hillside or ditch bed, reducing its stability, and the water-saturated solid accumulation moves under its own gravity, forming a debris flow. Mud...

Problems solved by technology

In addition, mudslides sometimes silt up the river, which not only blocks shipping, but also may cause floods

[0004] The occurrence and changes of debris flow disasters need to be accurately grasped through monitoring, and generally occur suddenly, the precursor phenomenon is not obvious, and most sudden debris flow disasters are active, so prediction, forecast and prevention are more difficult, and people are often caught off guard. cause serious damage

For debris flow disasters, more perfect monitoring technology must be adopted to provide a reliable basis for effective prevention and control of debris flow disasters, and to solve the problems of low accuracy, low efficiency and slow early warning response of existing debris flow disaster monitoring
