Wave monitoring plant for impending landslides

Abstract

The invention discloses a sound wave monitoring plant for landslide critical-slide, which comprises a pressure field sonic sensor, a monitoring host and a personal computer provided with landslide geologic hazard monitoring software, wherein the pressure field sonic sensor, the monitoring host and the personal computer provided with the landslide geologic hazard monitoring software are orderly connected; the monitoring host further processes a signal acquired by the pressure field sonic sensor; and the personal computer is used for storing, displaying, analyzing and prewarning the signal. The invention monitors the landslide by utilizing the sound wave information generated by rock rupture and friction when the sliding mass is in the impending state, can acquire predictive information before the sliding mass comes into the impending state and previously gives warning according to the software analysis, thereby reducing the loss of life and properties of people near the sliding mass due to the landslide.

Description

technical field [0001] The invention relates to the technical field of imminent landslide monitoring in geological disasters, in particular to an acoustic wave monitoring device for imminent landslides, which includes acoustic wave signal acquisition, program-controlled filtering, high-speed data processing and transmission, and expert decision-making and early warning of imminent landslides. Background technique [0002] Landslide is the most widely distributed and common geological disaster in my country, which is characterized by strong suddenness and great harm. Landslide dynamic monitoring has become an important means of disaster prevention and mitigation. [0003] For the regional investigation and dynamic monitoring of regional landslides, the traditional ways and means to obtain landslide status information are mainly to obtain the status information of non-key landslides through group monitoring and group prevention, and to obtain the status information of key land...

AI Technical Summary

Problems solved by technology

Due to the wide range of landslides in the region, the method of group monitoring and group prevention must consume a lot of manpower. Due to the limitation of monitoring methods, it is difficult to obtain the precursory information of the landslide body in time due to the limitation of monitoring methods, and it is often difficult to achieve the effect of early warning. Therefore, the traditional method has great big limitations

[0004] With the development of sensor technology, computer technology and network technology, it is proposed to use 3S technology, that is, Remote Sensing Technology (RS), Geographic Information System (GIS), and Global Positioning System (GPS) to monitor landslides, but many of the technical problems have not yet been solved. Fundamental solution; for example, how to directly transmit GPS monitoring data to GIS system to realize tracking and forecasting of landslide displacement. There is currently no good solution
