Oil and gas pipeline inspection system based on unmanned aerial vehicle aerial photo images and inspection method thereof

Abstract

The invention discloses an oil and gas pipeline inspection system based on unmanned aerial vehicle aerial photo images and an inspection method thereof. The system comprises an information collectionsystem, a ground mobile station and a data management center, wherein the information collection system is used for collecting image information along oil and gas pipelines and determining geographical location information of the images; the ground mobile station is used for reshipping equipment and processing and uploading collected data; and the data management center is used for communication with the ground mobile station and information interaction with a PC and a mobile terminal. According to the oil and gas pipeline inspection system based on unmanned aerial vehicle aerial photo imagesdisclosed by the invention, quick inspection can be realized along the oil and gas pipelines, and the dangerous conditions for the oil and gas pipelines such as irregular construction vehicles, illegal construction buildings and exposed ground surface appearing along the peripheries of the oil and gas pipelines can be automatically recognized, the inspection efficiency is greatly improved, and thelabor intensity of manual inspection is reduced.

Description

technical field [0001] The invention relates to an oil and gas pipeline inspection system and an inspection method thereof, in particular to an oil and gas pipeline inspection system and an inspection method based on drone aerial images. Background technique [0002] The line inspection of the pipeline is mainly manual inspection. Due to the long distance of the oil pipeline, the wide distribution range, and the complex environment, the traditional manual inspection method is costly, inefficient, and has great potential safety hazards. For example, in some harsh terrain and weather conditions , personnel are difficult to reach; in recent years, oil and gas pipeline practitioners have analyzed and applied UAVs in pipeline inspection. The name is a UAV-based oil and gas pipeline inspection system and inspection method, which includes a UAV body and a ground station; a flight control system, a task execution system, and a voltage stabilization module are arranged in the UAV bod...

AI Technical Summary

Problems solved by technology

But it has the following problems: First, it can only replace manual inspection and store the results of the inspection, and it cannot analyze the specific conditions in the inspection results (for example: engineering vehicles that appear within the scope of the pipeline, construction after construction) exposed ground, illegal buildings, and naturally formed surface damage, etc.) for automatic identification and distinction. On the oil and gas pipelines of about 120,000 kilometers in my country, the workload of manual sorting for the specific conditions in the vicinity is still very large; the second is, It cannot push the detection information to the inspection personnel in real time, nor can it push the different types of detection results to the corresponding regulatory departments, nor can it classify the data into the database, which is not conducive to the cooperation between various regulatory departments, and is also not conducive to the inspection data. Classified warehousing and follow-up inspection by supervisory personnel; third, the inspection efficiency is still very low, and it is not conducive to the rapid discovery and timely stop of potential dangers on oil and gas pipelines.
