Problems solved by technology

However, the above-mentioned monitoring methods need to send field workers to the landslides that are dangerous or difficult to reach, and carry out relevant field operations.
Therefore, the current technical means and their devices and equipment are difficult to install or maintain during their work. At the same time, in areas of sudden geological disasters that urgently need to be monitored, it is difficult to quickly arrange and have poor timeliness. At the same time, it also increases installation and construction. Cost and safety concerns for installers

Abstract

The invention mainly relates to the technical field of landslide monitoring. The invention discloses a projection type landslide monitoring device. The device mainly comprises a nose cone, a reducingcoupling cavity, a load cabin and empennages, wherein the top end of the nose cone is of a conical structure, the bottom end is coupled with a reducing port of the reducing coupling cavity, the inneris hollow, the load cabin is arranged at the other end of the reducing coupling cavity, the empennages are arranged on the left and right sides of the load cabin respectively, an infrasound sensor, adata acquisition module, a communication module and a lithium battery are arranged in the load cabin, the lithium battery is used for supplying power, the infrasound sensor monitors the sound wave, the data acquisition module acquires infrasonic wave signals, the acquired infrasonic wave signals are transmitted to the central server through the communication module. The unmanned aerial vehicle isused for carrying the projection type landslide monitoring device, so that an operator can work far away from a geological disaster site, the safety problem of the operator is solved, meanwhile, the projection type landslide monitoring device can be deployed in a short time, and the timeliness of geological disaster monitoring is improved.

Description

technical field [0001] The invention relates to the technical field of landslide monitoring, in particular to a projected landslide monitoring device, system and method. Background technique [0002] Natural disasters such as landslides, debris flows and collapses occur frequently in our country. For geological disasters such as landslides and debris flows, various research institutions have launched their own monitoring methods, including displacement monitoring, stress and strain monitoring, groundwater dynamic monitoring, surface water dynamic monitoring, geoacoustic monitoring, and radioactive elements. monitoring, monitoring of environmental factors and monitoring of macroscopic phenomena, etc. However, the above-mentioned monitoring means need to send field workers to the landslide body that is dangerous or difficult to climb to reach, and carry out relevant field operations to carry out. Therefore, the current technical means and their devices and equipment are diffi...
