Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil pipeline detection, in particular to an oil pipeline anti-stealing system and a control method thereof. BACKGROUND

[0002] The oil pipeline (also known as pipeline or pipe line) is composed of oil pipes and accessories, and is equipped with corresponding oil pump units according to the needs of the process flow, and is designed and installed as a complete pipeline system to complete the oil loading and unloading and transfer task. The oil pipeline system, i.e. the pipeline system for transporting oil and oil products, is mainly composed of oil pipelines, oil stations and other auxiliary related equipment, and is one of the main equipment in the oil storage and transportation industry, and is the most important oil and oil product transportation equipment. Compared with railway and highway oil transportation which also belongs to land transportation, pipeline oil transportation has the characteristics of large transportation capacity, good sealing, low cost and high safety factor.

[0003] In the production and operation of the oil pipeline, the phenomenon of stealing oil by drilling pipe often occurs. This way of stealing oil is generally by digging a tunnel near the oil pipeline, then drilling the oil pipeline (drilling hole), and then connecting the oil product to the illegal operation area several kilometers away through the self-owned oil pipeline to achieve the purpose of stealing oil. This method has the characteristics of hidden operation and long-term oil stealing, and is difficult to be found, which causes huge economic losses to the normal production work. At present, the main methods for detecting whether the oil pipeline is damaged or stolen by drilling include ultrasonic sensor and vibration sensor. The detection principle of the vibration sensor is to detect the vibration phenomenon caused by drilling the oil pipeline, and to judge whether the oil is stolen by the vibration signal. The judgment basis is whether it is greater than the threshold value. If the oil pipeline has abnormal vibration due to non-stealing behavior such as hitting a rock or pipeline maintenance, the detection result will also be that the oil is stolen, which is inconsistent with the actual situation, so there is a problem of false detection. In addition, the existing oil pipeline detection technology only has detection function and does not have post-analysis technical support. The proportion is analyzed according to the returned detection data to obtain the corresponding processing conclusion. The present application is designed to solve the above problems. SUMMARY
