A water inrush perception and early warning system and method for karst tunnels based on the Internet of Things

Abstract

The invention discloses a water inrush perception and early warning system and method based on the Internet of Things in karst tunnels, including a multi-information perception platform layer for tunnel water inrush precursors, a sensory data network transmission, storage and analysis layer, and a disaster classification early warning layer; tunnel water inrush precursors The multi-information perception platform layer uses the sensing terminal to collect data information and distributes it to the perception data network transmission, storage and analysis layer, and the perception data network transmission, storage and analysis layer receives tunnel water inrush precursor multi-information perception platform layer transmission The data is stored in the spatial data warehouse, and the cloud computing service platform is used to analyze and process the data, and the analysis results are issued through the four-color early warning platform through the disaster grading early warning layer. Realized rapid real-time monitoring of multiple precursor information of water inrush disasters, and completed scientific storage, rapid processing, and timely release of monitoring data at the same time, reducing construction delays, construction personnel casualties, and mechanical equipment damage caused by water inrush in tunnels.

Description

technical field [0001] The invention relates to a system and method for sensing and early warning of water inrush in karst tunnels based on the Internet of Things. Background technique [0002] The Internet of Things is an Internet where things are connected. Based on the Internet of Things technology, the tunnel construction safety is integrated with the Internet to form a tunnel Internet of Things technology based on the Internet. [0003] During the construction of tunnels in karst areas, disasters such as water inrush and mud inrush often occur. The occurrence of disasters will affect the tunnel construction period, increase construction costs, damage mechanical equipment, and seriously endanger the lives of construction workers. When tunnel water inrush occurs, it will be accompanied by changes in various precursor information, such as changes in surrounding rock displacement, stress and strain, osmotic pressure, and temperature field. [0004] At present, the applic...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem that monitoring personnel cannot implement all-weather, real-time and continuous monitoring of tunnel surrounding rock displacement changes, it is difficult to obtain multivariate information on water inrush precursors, and it is impossible to obtain accurate multivariate information field data on water inrush precursors under harsh construction conditions. The data is stored and analyzed Time-consuming and labor-intensive, delay in feedback of data analysis results, inability to quickly evacuate on-site construction personnel after disaster warning, etc.
