Method and system for monitoring safety of oil and gas pipeline based on unmanned aerial vehicle line patrol, and software storage device

Abstract

The invention discloses a method and a system for monitoring safety of an oil and gas pipeline based on unmanned aerial vehicle line patrol and a software storage device. The method comprises the steps of S1, acquiring multi-source data generated by safety monitoring of the oil and gas pipeline with an unmanned aerial vehicle; S2, carrying out risk identification on a mono-temporal image accordingto a characteristic library obtained by historical risk characteristic training, carrying out the risk identification on a multi-temporal image by use of a saturation-based change detection method toidentify change regions between different time phases, calculating and combining mono-temporal and multi-temporal risk identification results; S3, reappearing an inspection process of the unmanned aerial vehicle for the oil and gas pipeline in a three-dimensional platform; S4, carrying out route planning of the unmanned aerial vehicle inspection and analysis of a water-flooded space of the pipeline; and S5, outputting a pipeline hidden danger report which includes a risk identification report and a spatial analysis report, and making a decision according to the pipeline hidden danger report.According to the method and the system for monitoring the safety of the oil and gas pipeline based on unmanned aerial vehicle line patrol and the software storage device, the safety management cost ofthe oil and gas pipeline is effectively reduced, the safety monitoring efficiency is improved and the operation and maintenance management level of a pipe network is enhanced.

Description

technical field [0001] The invention relates to the field of intelligent safety management of oil and gas pipelines, in particular to an oil and gas pipeline safety monitoring method, system and software memory for line inspection by 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 way of oil and gas transportation in the world today due to its advantages of low cost, energy saving, and stable supply. However, the pipeline transportation method has the characteristics of long transportation distance, large pipe 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 At the same time, it will also pose a huge threat t...
