Underground engineering surrounding rock stability multi-physical-field monitoring and early warning system and method

Abstract

The invention discloses an underground engineering surrounding rock stability multi-physical-field monitoring and early warning system and method. The system comprises an underground monitoring subsystem and a ground monitoring and early warning subsystem. The underground monitoring subsystem comprises a multi-physical-field sensing system, a monitoring substation and an industrial looped network.The ground monitoring and early warning subsystem comprises a multi-physical-field data acquisition and storage system, a remote data real-time processing and analysis system and an intelligent earlywarning system; the multi-physical-field sensing system is connected with the monitoring substation, and the monitoring substation is connected with the industrial looped network through a communication optical fiber and a network communication master station, or the monitoring substation is connected with the industrial looped network through a 5G micro base station and a 5G core base station insequence; the industrial looped network is connected with the multi-physical-field data acquisition and storage system, the multi-physical-field data acquisition and storage system is connected withthe remote data real-time processing and analysis system in a wireless mode, the remote data real-time processing and analysis system is connected with the intelligent early warning system, the manualworkload is effectively reduced, the intelligent degree is high, and the real-time performance is high.

Description

technical field [0001] The invention relates to the technical field of safety testing in underground geotechnical and mining engineering, and more specifically relates to a multi-physical field monitoring and early warning system and method for surrounding rock stability of underground engineering. Background technique [0002] With the rapid development of our society, the pace of underground engineering construction is accelerating, and the safety issues under the influence of natural or man-made disturbance loads are becoming more and more complicated. People are more urgent to use underground space scientifically, safely and accurately, and exploit resources. [0003] It is particularly important to conduct in-depth research on the stability of surrounding rock structures in underground engineering. Among them, the movement and deformation of rock and soil layers, the development of rock and soil mass cracks and structural deformation and damage, groundwater seepage or P...

AI Technical Summary

Problems solved by technology

[0004] At this stage, there are still the following problems in the field of monitoring and analysis of deformation and damage of surrounding rock structures in underground engineering: the existing monitoring system is low in intelligence, requires manual collection, and has a large workload. There are supporting ground remote monitoring and intelligent early warning systems. It is not yet mature, limited by the high delay of the network monitoring system, the monitoring data is dynamically and synchronously collected, transmitted, processed and analyzed, and the effect of intelligent early warning is poor
