Mountain torrent debris flow high-hidden-danger area monitoring and early warning system

Abstract

The invention relates to the field of geological disaster safety monitoring and particularly relates to a mountain torrent debris flow high-hidden-danger area monitoring and early warning system. Thesystem comprises a mountain torrent debris flow high-hidden-danger area, a mountain positioning monitoring rod, a power supply device, a safety data synchronous acquisition module and an ultra-small double-in-line signal receiving and transmitting device. The safety data synchronous acquisition module is composed of a resistance-type strain gauge sensor, a water level pressure sensor and a water flow pressure sensor. The acquisition modules are arranged around an outer side of the mountain positioning monitoring rod; anchor cables for fixing prestressed tendons can actively stabilize a local slope surface; a local safety data processing module carries out denoising, amplification and signal standardization processing on collected environment sensing data and image signals and then transmits the processed signals to a local monitoring center; and the local monitoring center calculates and judges the received information and transmits the information to a remote network monitoring terminal. Therefore, early warning is performed in time when mountain torrent debris flow disasters happen, and an effect of reinforcing a local foundation is achieved.

Description

technical field [0001] The invention relates to the field of geological disaster safety monitoring, in particular to a monitoring and early warning system for areas with high hidden dangers of mountain torrents and debris flows. Background technique [0002] Flash floods and mudslides are the process of rapid transport of water and soil materials in small watersheds in mountainous areas. They erupt suddenly and have strong destructive power, often causing devastating disasters. The combination and superposition of factors such as active geological structure, huge terrain elevation difference, abundant rainfall brought by the monsoon climate, dense population distribution, and high-intensity human activities have made mountain torrents and debris flows widely developed in areas accounting for about 2 / 3 of China's land area. 3 mountainous areas, frequent disasters. [0003] In recent years, mountain torrents and debris flow disasters have seriously threatened the lives and pr...

AI Technical Summary

Problems solved by technology

At present, most of the judging factors of the existing automatic monitoring and early warning systems for torrent and debris flow disasters in China are relatively single. The collation and analysis of data is even more difficult to meet the needs of the project, and the traditional method of monitoring and early warning of torrents and debris flows is to establish simple survey points in mountainous areas and adopt simple survey methods, that is, to rely mainly on manual surveys of rainfall and early warning after the occurrence of debris flows. The technical content of the instrument is not high, and the communication is stuck in bad weather, especially the monitoring and early warning work at night is difficult to implement
