Real-time monitoring system and method for deep displacement of landslide based on sound source localization

Abstract

The present invention provides a landslide deep displacement real-time monitoring system and method based on sound source location, which includes an ultrasonic generating device for generating ultrasonic waves, and the ultrasonic generating device is matched with an ultrasonic receiving device for receiving and detecting ultrasonic signals. The ultrasonic receiving device is connected to the data processing module through the data transmission module; the ultrasonic receiving device is arranged below the surface of a relatively stable area; the ultrasonic generating device is arranged below the surface of the landslide-prone area to be monitored. The device can realize the normal acquisition of the whole process of landslide sliding, accurately calculate the deep displacement change trend of the landslide in the stage of imminent sliding, and has guiding significance for the prediction of the sliding direction and sliding time of the landslide.

Description

technical field [0001] The invention relates to a real-time monitoring system and method for deep displacement of landslides based on sound source positioning, in particular to a recyclable real-time monitoring system that can meet the large deformation monitoring requirements at monitoring points. Background technique [0002] Landslides are one of the major geological disasters worldwide, often causing casualties, road burial, and house damage, seriously threatening the safety of life and property. Monitoring and early warning, as one of the important measures to mitigate the risk of geological disasters, is getting more and more attention. The occurrence, development and evolution of landslides is accompanied by changes in a large number of macroscopically measurable physical information, such as surface displacement, deep displacement, surface inclination, rock and soil mass pressure, and acoustic emission. Among the many measurable physical quantities, the surface disp...

AI Technical Summary

Problems solved by technology

[0005] 1. It is difficult to monitor the large displacement in the adjacent sliding stage of the landslide: the inclinometer monitoring method inclinometer cannot enter the large deformation measurement borehole; the deformation capacity of the cable is limited, and the large deformation stage may have been damaged;

[0006] 2. It is impossible to collect data in severe weather (thunder, rainstorm, flooding, freezing, etc.), and there are personal safety and equipment safety problems at this time;

[0007] 3. The installation and construction process of the collection device is relatively complicated;

[0008] 4. The acquisition cost is high and the cost is large

[0009] Therefore, the monitoring of the whole process of landslide sliding cannot be realized, especially the stage of sliding, and the monitoring and early warning task at this stage is particularly important, and high reliability, real-time uninterrupted, low power consumption, and low-cost acquisition cannot be realized
