Oil and gas pipeline safety monitoring method, system and software memory based on UAV line patrol

Abstract

The invention discloses an oil and gas pipeline safety monitoring method, system and software memory based on UAV line inspection. The method includes: S1, acquiring multi-source data generated by UAV oil and gas pipeline safety monitoring; S2, according to historical risk characteristics The trained feature library is used for risk identification of single-temporal images; for multi-temporal images, the saturation-based change detection method is used for risk identification to identify the change areas between different temporal phases; for single-temporal and multi-temporal risk The identification results are calculated and combined to obtain high-precision risk identification results; S3. Reproduce the inspection process of oil and gas pipelines by UAVs on the 3D platform; S4. Route planning for UAV inspections and analysis of pipeline water flooding space ; S5 , outputting a pipeline hidden danger report, including a risk identification report and a spatial analysis report, and assisting decision-making based on the pipeline hidden danger report. The invention effectively reduces the safety management cost of the oil and gas pipeline, improves the safety monitoring efficiency, and improves the operation and maintenance management level of the pipeline network.

Description

technical field [0001] The invention relates to the field of intelligent safety management of oil and gas pipelines, in particular to a method, system and software storage for oil and gas pipeline safety monitoring of unmanned aerial vehicles. Background technique [0002] With the development of the oil and gas industry and the continuous internationalization of oil and gas trade, pipeline transportation has become an increasingly important oil and gas transportation method in the world today due to its advantages of low cost, energy saving, and stable supply. However, the pipeline transportation mode has the characteristics of long transportation distance, large diameter, high pressure and large transportation volume. Once an accident occurs along the long-distance pipeline, it will not only affect the normal operation of the pipeline, but also when transporting toxic, flammable and explosive media. It will also pose a huge threat to people's life, property and living envi...
