Dangerous rock collapse monitoring system and monitoring method

Abstract

The invention relates to the field of geological disaster prevention and control, and discloses a dangerous rock collapse monitoring system and method.The dangerous rock collapse monitoring system comprises dangerous rock state monitoring devices, a data acquisition and analysis device, a power supply device and a background server, wherein the dangerous rock state monitoring devices are arranged on the periphery of dangerous rock to monitor dangerous rock state information in real time; the data acquisition and analysis device acquires and analyzes state information in a certain period and outputs analysis data, the background server receives and displays the analysis data, and an alarm prompt is given when data abnormity exists. According to the invention, a monitoring mode with a vibrating wire sensor as a main part and an acceleration sensor as an auxiliary part is adopted, the change stress value of the vibrating wire sensor is a reliable and special means for monitoring deformation and collapse of the rock mass, the design deficiency of a collapse meter with an accelerometer as a main part is made up, the change process of the stress value of the rock mass can be really monitored, and pre-warning of collapse is realized; and short and precious time is provided for evacuation of the masses.

Description

technical field [0001] The invention relates to the field of geological disaster prevention and control, in particular to a dangerous rock collapse monitoring system and monitoring method. Background technique [0002] my country is a mountainous country, and it is also a country with frequent geological disasters. With the rapid construction of roads and railways and the rapid development of urban construction in mountainous areas, due to physical weathering of rock and soil, in many conditions such as precipitation, earthquakes, human activities, etc. Under the trigger, natural disasters such as rock and soil collapses will easily cause damage to roads, railways and houses, which has increasingly aroused human attention to the geological safety of mountains. [0003] The patent with the publication number CN211905422U discloses a low-power avalanche gauge, which adopts the hardware design method of an acceleration sensor, a communication module, an analog-to-digital convers...

AI Technical Summary

Problems solved by technology

Expansion nails are used to directly fix the object under test. The fixing method is strict, and there are monitoring blind spots when the whole rock falls instantly, which makes the equipment unable to identify and issue early warning in time. Lack of effective data statistics and analysis, it is impossible to grasp the occurrence law of geological disasters , preventive measures cannot be taken in advance, resulting in a passive response after the disaster occurs, so the design of the existing avalanche gauge is not suitable for the site scene of dangerous rock avalanche

[0004] Since most rock collapses happen instantaneously, the existing collapse plans all belong to post-event alarms, and personnel cannot evacuate in time
