Monitoring early warning device and method for torrent and debris flow geological disasters

Abstract

The invention discloses a monitoring early warning device and method for torrent and debris flow geological disasters. The monitoring early warning device is formed by field sensing devices with numbers of 1-n and one terminal alarm device; the distances between the field sensing devices and the terminal alarm device are sequentially arrayed in a numbered mode from far to near; the terminal alarm device performs transmission control and signal collecting on the field sensing devices. Sensors of the field sensing devices are formed by combining multiple sensors; the terminal alarm device collects the signals of the field sensing devices in a wireless communication relay transmission mode for controlling, intermittent power supply control is performed on electrified control modules in sensing controllers of the field sensing devices according to needs, and the transmission control with the field sensing devices is performed according to the relay transmission wireless communication mode. An energy-saving strategy is adopted, the sensing devices can stably work under the condition of self powering, the cost is low, the monitoring range is wide and is in network distribution, the monitoring contents are more, and the device and the method provide, new, wider and more comprehensive judgment basis for torrent and debris flow.

Description

1. Technical field [0001] The invention relates to monitoring and early warning of geological disasters, in particular to monitoring and early warning of mountain torrents and debris flows. 2. Background technology [0002] The destructive power of mountain torrents and mudslides is huge, and the monitoring and early warning of torrents and mudslides is the key to preventing huge human and material losses. However, due to many uncertainties and difficulties in monitoring and early warning, it causes a large number of human and property losses every year, and even leads to the destruction of families. With the increase of economic strength, the country has invested a lot of manpower and material resources in monitoring and early warning of torrents and debris flows. Many monitoring and early warning methods and devices have emerged as the times require, which have played a good role in the monitoring and early warning of debris flows. However, since the monitoring and early ...

Problems solved by technology

However, since the monitoring and early warning must be in a very harsh environment, there are high requirements for the monitoring device itself, especially the energy problem required by the monitoring device itself is difficult to solve satisfactorily. At the same time, debris flow is affected by various factor
