Petroleum transmission pipeline inspection system

Abstract

The invention belongs to the field of unmanned aerial vehicle detection, and in particular relates to an oil pipeline inspection system, including a sensing optical cable, an unmanned aerial vehicle, a ground inspection vehicle, and a monitoring center; wherein, the sensing optical cable is installed outside the oil pipeline, and The monitoring center is connected by communication; the UAV and the ground patrol vehicle, and between the ground patrol vehicle and the monitoring center are connected wirelessly; the present invention adopts sensing optical cable and UAV remote sensing technology to observe through the camera , quickly locate the location of the event, and transmit the monitoring video to the rear site in real time through the data link, which can avoid the impact of terrain on the line inspection, make up for the lack of manual inspection due to terrain reasons that cannot be approached in time, improve the efficiency of line inspection, and are widely applicable to Pipeline routine inspections, large-scale regional inspections, and then with the help of ultra-narrowband video remote transmission technology, the cruise video is transmitted in real time to consoles or mobile terminals located in any geographic location, providing effective protection for pipeline protection.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle detection, and in particular relates to an oil pipeline inspection system. Background technique [0002] Oil and gas resources, as important energy sources and raw materials for many chemical products, play a pivotal role in many aspects such as national life, industrial and agricultural production, and national defense construction. Due to its high reliability and low transportation cost, the pipeline transportation system has been widely used in oil, natural gas and other industrial sectors as a safe and economical transportation method. This has caused huge economic losses, which makes the automatic monitoring technology of oil and gas pipelines more and more important. [0003] At present, the relatively mature pipeline leakage detection technology at home and abroad can be roughly divided into two categories: internal detection and external detection. Internal detection methods include...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned technologies are limited by various factors such as detection principle, sensor performance, sampling point density, etc., so it is difficult to simultaneously meet the detection sensitivity (only a large amount of leakage can be found), positioning accuracy (500m-1000m), false alarm Rate and timely alarm (100s level) and other requirements

In addition, these methods are greatly affected by the terrain environment of the patrol line, and have a strong dependence on the experience of the monitoring personnel, and have many shortcomings in the process of long-distance signal transmission
