Natural gas pipeline settlement early warning system based on unmanned aerial vehicle inspection

Abstract

The invention discloses a natural gas pipeline settlement early warning system based on unmanned aerial vehicle inspection. The natural gas pipeline settlement early warning system comprises a remotecontrol platform, an unmanned airborne platform and a mobile base station, wherein the remote control platform is used for planning an inspection route of an unmanned aerial vehicle according to a natural gas pipeline layout and transmitting real-time earth's surface image information in each region to the remote control platform. Meanwhile, the control platform extracts the latest image feature value by virtue of an image recognition technology, performs comparative analysis with an image feature value in the previous day, calculates ground depression and ground surface fissure width per dayat corresponding positions, derives a detecting techniques table and finally gives early warning to a region exceeding a set value. The mobile base station is matched with the unmanned aerial vehicleto complete information acquisition and card punching. According to the natural gas pipeline settlement early warning system disclosed by the invention, the traditional manual inspection is changed, the working efficiency of pipeline inspection is improved, the labor cost is reduced, and the safety and stability of the pipeline are ensured.

Description

technical field [0001] The invention relates to a system for automatic inspection of ground-building facilities by unmanned aerial vehicles, in particular to an inspection and early warning system for subsidence of ground-building natural gas pipelines by using unmanned aerial vehicles. Background technique [0002] Shanxi is a major province in the development of coal resources. The area of ​​underground mined-out area caused by coal mining reaches more than 5,000 square kilometers every year, forming a goaf subsidence area of ​​nearly 3,000 square kilometers. The goaf subsidence area will cause ground subsidence, subsidence deformation and Secondary geological disasters such as cracking. The stretching, bending, and shearing deformation of the pipeline driven by these geological disasters will cause pipeline leakage, which is extremely unfavorable to the management and operation of the pipeline. Implementation poses a potential risk. [0003] At present, domestic natural ...

[0002] Shanxi is a major province in the development of coal resources. The area of ​​underground mined-out area caused by coal mining reaches more than 5,000 square kilometers every year, forming a goaf subsidence area of ​​nearly 3,000 square kilometers. The goaf subsidence area will cause ground subsidence, subsidence deformation and Secondary geological disasters such as cracking. The stretching, bending, and shearing deformation of the pipeline driven by these geological disasters will cause pipeline leakage, which is extremely unfavorable to the management and operation of the pipeline. Implementation poses a potential risk

[0003] At present, domestic natural gas pipeline detection mainly adopts manual line inspection, and local residents are hired as inspectors. The inspectors go back and forth 15 kilometers a day to inspect the natural gas pipeline lines. This work consumes a lot of manpower and requires high technical requirements for inspectors. Difficult operation and some routes crossing mountains and seas make it difficult to guarantee the detection effect of natural gas pipelines, leaving hidden dangers for the prevention of natural gas line settlement. Therefore, it is urgent to research and develop an early warning system for the prevention of natural gas line settlement
