Security monitoring system and method of tailings pond based on unmanned aerial vehicle and three-dimensional modeling technology

Abstract

The invention provides a security monitoring system and method of a tailings pond based on an unmanned aerial vehicle and a three-dimensional modeling technology. An image acquisition module is used for acquiring geographical information of a to-be-detected tailings pond; a data compression module is equipped with an encoder supporting an onvif protocol and used for compression coding of an acquired video signal, an audio signal and a data signal of the to-be-detected tailings pond; a wireless transmission module is equipped with antennas of 2.4 GHz and 5.8 GHz frequency bands and used for wireless data transmission between a geographical information acquisition unmanned aerial vehicle group and a daily tour inspection monitoring unmanned aerial vehicle group; a cluster operation module isused for performing cluster operation image processing on obtained image geographical information data of the to-be-detected tailings pond; and a three-dimensional modeling module is used for performing aerotriangulation resolution and remodeling on the obtained geographical information data of the to-be-detected tailings pond. According to the system and method, all-weather monitoring of surrounding environments including onsite transmission tail pipelines, tailings dams, water lines, phreatic lines, and tailings ponds without dead angles can be realized.

Description

technical field [0001] The invention relates to the technical field of safety monitoring, in particular to a tailings pond safety monitoring system and method based on unmanned aerial vehicle and three-dimensional modeling technology. Background technique [0002] Tailings pool refers to the place where dams are built to intercept valley mouths or enclosures, and are used to stockpile metal or non-metal mines for ore sorting and then discharge tailings or other industrial waste. At present, my country has put special emphasis on the safety supervision of tailings pond facilities in the form of legislation, among which the regulations issued include the "Regulations on the Safety Supervision and Management of Tailings Ponds". In addition, the State Administration of Work Safety's "Notice on Printing and Distributing the Comprehensive Treatment Plan for Hidden Hazards of Tailings Ponds" (Safety Supervision and Administration One [2009] No. Opinions" (Safety Supervision Genera...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the embodiments of the present invention is to provide a tailings pond safety monitoring system and method based on unmanned aerial vehicles and three-dimensional modeling technology to realize on-site tailings transportation pipelines, tailings dams, water level lines, infiltration lines, and the surrounding environment of tailings ponds The "no dead angle", "all-weather" monitoring and data processing analysis, recording, and simulation solve the problems of low monitoring efficiency, inaccurate and incomplete data recording, poor comparability, poor retention, and insufficient nighttime inspection of existing tailings ponds. question
