Intelligent warning system for computation and pipe monitoring of oil transportation collection and transmission system

Abstract

A measuring and conduit monitoring and controlling alarm system of an oil collection and transportation system comprises a crude oil metering system and a conduit monitoring and controlling alarm system both of which are connected together with a butt joint by a crude oil metering system interface, wherein the crude oil metering system comprises a data acquiring and memorizing module, a production data monitoring and controlling module and a store-and-forward data module; the conduit monitoring and controlling alarm system comprises a data acquiring module, a data preprocessing module, a intelligent analyzing alarm module, a leakage recognizing module, a center server module, and a monitoring and controlling user terminal. The invented measuring and conduit monitoring and controlling alarm system of an oil collection and transportation system is a full automatic intelligentized system provided with a friendly man-machine interface, accurate localization and accurate alarming.

Description

technical field [0001] The invention belongs to the technical field of oil pipelines in the petroleum industry, and more specifically relates to an intelligent alarm system for metering and pipeline monitoring of an oil gathering and transportation system based on graphic processing technology and communication technology. Background technique [0002] In recent years, oil thieves have frantically drilled holes in pipelines to steal oil and gas. Once an oil and gas accident occurs, not only the pipeline is forced to stop, normal production cannot be carried out, but also the environment is polluted, and the compensation costs are high. If the stoppage time is too long, it will cause a vicious accident of the whole line of condensation pipes, and the loss is immeasurable. Oil thieves use a variety of methods to commit crimes. The means are becoming more and more subtle, and the way of stealing oil is becoming more and more cunning. From digging holes on the side of the road a...

AI Technical Summary

Problems solved by technology

[0005] ① There are many external factors, and the false alarm rate is high. The alarm is often reported when there is no oil theft, and the alarm is not reported when the oil is actually stolen;

[0006] ②The influence of production factors is large. For example, in order to save energy and reduce consumption, most stations adopt oil-gas sealed gathering and transportation, and adopt frequency conversion control. However, the pipeline monitoring system requires stable pressure and pressure fluctuations are not allowed, resulting in the failure of most pipeline monitoring. However, the open process is used for production, and the crude oil loss rate is high;

[0007] ③The leakage rate monitored by most of the previous monitoring systems is about 10%, and the small leakage rate cannot be monitored
