Oil and gas pipeline area intrusion detection device and method

Abstract

The invention provides an oil and gas pipeline area intrusion detection device and method. The method includes that whether a moving object belongs to human intrusion or not is judged through changesof the volume or contour of the moving object, swinging of grass and trees and the like due to wind can be effectively excluded, and false alarm rate is reduced; features that the embedding area of oil and gas pipelines is remote and is difficult to be connected to wired network are fully considered, and 3G, 4G or 5G networks are adopted; when an analysis processor determines that the moving object is not in the pipeline safety line, or the moving object does not belong to human intrusion, or duration of stay of the moving object in the pipeline safety line is within a set threshold value, theanalysis processor controls a signal transmission module not to transmit images, both flow rate and electricity are saved, and use cost is saved. The facts that the embedding area of the oil and gaspipelines is remote and has difficulty in power supply are fully considered, storage batteries are adopted in combination with wind and light power generation, and energy self sufficiency is realized;the oil and gas pipeline area intrusion detection device and method is low in false alarm rate, high in recognition rate, high in cost performance and suitable for large-scale application.

Description

technical field [0001] The invention relates to the technical field of oil and gas pipeline safety, in particular to an oil and gas pipeline area intrusion detection device and method. Background technique [0002] Long-distance oil and gas pipelines are the most important transportation equipment for crude oil and petroleum products. Compared with railway and highway oil transportation, which are also land transportation methods, pipeline oil transportation has the advantages of large transportation volume, good airtightness, low cost and high safety factor. features. Within 5 meters on both sides of long-distance oil and gas pipelines, construction and other potential damage to pipelines are not allowed. Once the long-distance oil and gas pipeline leaks due to construction or other man-made damage, it will cause a major safety accident. Therefore, it is very necessary to find a detection scheme that can effectively detect the intrusion of objects around the pipeline. [...

AI Technical Summary

Problems solved by technology

Among them, the optical fiber sensor and the vibration sensor mainly use the method of detecting the vibration around the pipeline to detect whether there is construction or other damage to the pipeline around the pipeline. This method is limited by different geographical environmental conditions, resulting in inconsistent background noise, and the distinction between boundaries Not obvious, there is a high rate of false alarms and false alarms in actual monitoring, and the sensor is also easily damaged when the geology changes

Although the method of manual inspection can eliminate false alarms and clarify the safety range of pipelines, there are certain cases of missed reports and untimely supervision, and the inspection method is labor-intensive and expensive

The inspection methods at the current stage cannot achieve real-time supervision of construction within the safe range of the pipeline and other potential damage to the pipeline, leaving a safety hazard for the safe production of the pipeline
