UAV detection based high-rise building natural gas riser safety early warning system

Abstract

The invention relates to a UAV detection based high-rise building natural gas riser safety early warning system. The system uses an unmanned aerial vehicle as a carrier to detect a natural gas pipeline, and the whole pipeline detection process does not require human on-site participation, and the pipeline detection process is safer. At the same time, the system integrates the thermal infrared technology, the smoke detection technology and the sound wave detection technology into pipeline parameter detection, and obtains more accurate and reliable pipeline information through multi-parameter detection, and provides faster and more accurate information reference for timely judgment of subsequent pipeline abnormal causes.

Description

technical field [0001] The invention relates to the field of UAV remote sensing technology and the field of natural gas pipeline safety detection technology, in particular to a high-rise building natural gas riser safety early warning system based on UAV detection. Background technique [0002] At present, the amount of laying of various natural gas pipelines is increasing. Some of the pipelines are erected on the outside of high-rise buildings, and the laying height and coverage are relatively large. The danger cannot be ignored, which puts higher requirements on the management of natural gas risers. Although the existing detection methods, such as optical fiber detection methods, have realized the investigation of natural gas riser leakage points to a certain extent, but in natural gas When the temperature difference of the pipeline is large, leakage may occur, or it may be caused by thermal expansion and contraction due to excessive local temperature, which may easily dam...

[0002] At present, the amount of laying of various natural gas pipelines is increasing. Some of the pipelines are erected on the outside of high-rise buildings, and the laying height and coverage are relatively large. The danger cannot be ignored, which puts higher requirements on the management of natural gas risers. Although the existing detection methods, such as optical fiber detection methods, have realized the investigation of natural gas riser leakage points to a certain extent, but in natural gas When the temperature difference of the pipeline is large, leakage may occur, or it may be caused by thermal expansion and contraction due to excessive local temperature, which may easily damage the natural gas pipeline. When a leakage occurs, the optical fiber detection method is inconvenient to obtain information such as the leakage situation and the cause of the leakage. In this way, maintenance personnel cannot obtain more detailed pipeline information in time and cannot take targeted solutions
