Early warning method and system based on pipeline integrity

Abstract

The invention provides an early warning method and system based on pipeline integrity. The early warning method comprises the steps: establishing a pipeline risk assessment system; collecting and storing basic data of each pipeline of the pipeline; identifying the pressure grade of each pipeline according to the basic data of each pipeline, and scoring the index item of each pipeline according toa preset scoring standard to obtain a special risk scoring matrix of each pipeline; performing comprehensive risk scoring according to the basic data of each pipeline and the corresponding special risk scoring matrix to obtain a comprehensive risk level of each pipeline; and executing different risk measures according to the comprehensive risk level. The early warning method aims to establish a professional pipeline flow, and calls the pipeline body and operation data in real time and makes an intelligent decision through the early warning system, so that errors caused by manual judgment of pipeline risks are greatly reduced, and accidents are prevented in advance, and the cost is reduced, and the pipeline maintenance efficiency is improved, and the pipeline maintenance cost is reasonablydistributed, and the purpose of ensuring and preventing safe operation of the pipeline is achieved.

Description

technical field [0001] The invention relates to the technical field of gas pipelines, in particular to an early warning method and system based on pipeline integrity. Background technique [0002] With the development of science and technology, pipeline gas has been widely used in people's lives, and the laying of gas pipelines is growing around the development of cities. Most pipelines pass through densely populated areas and living areas. How to ensure While people use high-quality natural gas energy, they can also maintain the safe operation of gas pipelines, which has become a top priority for gas workers. Based on this, the pipeline integrity management technology PIM (Pipeline Integrity Management) was conceived and gradually applied to gas pipelines. The existing mature pipeline models mainly include PODS, ISAT, APDM, etc., and have been successfully applied to major gas companies. [0003] However, due to the different geographical locations of the gas pipelines of ...

AI Technical Summary

Problems solved by technology

[0003] However, due to the different geographical locations of the gas pipelines of major gas companies, as well as the differences between the north and the south and the differences in weather and climate, the gas pipeline integrity management technology learned from the experience cannot be applied to major gas companies according to uniform standards. Moreover, the data in the existing gas pipeline maintenance system operate independently of each other, cannot be shared and combined, and cannot quickly and accurately judge pipeline risks, greatly increasing the risk management and maintenance costs of operating pipelines, resulting in frequent occurrence of risk accidents
