Embodiment approach

[0078] In the above-mentioned embodiment, there is no limitation on how to execute step S103. In this embodiment, an implementation method is given to verify that the assignment of each risk weight value satisfies the conditions by using a pre-built consistency verification relational expression. Please refer to image 3 , which can include the following:

[0079] S1031: Based on the risk estimation model, the relative importance of each indicator is obtained by using a scaling method in advance, so as to construct an indicator weight judgment matrix.

[0080] After constructing the risk estimation model, a scale method such as A.L.Saaty1-9 can be used to construct the ring index weight judgment matrix A by weighting and judging the relative importance of each index based on the information contained in the risk estimation model. Specifically, the questionnaire method can be used to obtain the weight comparison among the various indicators of the scoring expert group. Accordi...

Abstract

The invention discloses a circumferential weld risk estimation method and device for a conveying pipeline and a computer readable storage medium. The method comprises the steps that a risk predictionmodel corresponding to a circumferential weld of a conveying pipeline is determined based on basic parameter data of the urban building group conveying pipeline; wherein the risk prediction model comprises risk level information, score ranges corresponding to the risk levels, an index set for evaluating circumferential weld risks and scoring ranges of the indexes; based on the risk prediction model, the risk weight value and score value of each index of the circumferential weld are automatically calculated according to the detection data in the pipeline and the basic parameter data; when the consistency check relational expression is used for checking that the assignment of each risk weight value meets the condition, based on the risk weight value and the score value, the degree of association between each index and the risk level of the circumferential weld is determined by using a circumferential weld risk association relation to obtain the risk estimation information of the circumferential weld, thereby effectively reducing the degree of influence of human subjective factors on the circumferential weld risk estimation process, and improving the accuracy of circumferential weld risk estimation of the conveying pipeline.

Description

technical field [0001] The present application relates to the technical field of safety monitoring of transmission pipelines, in particular to a method, device and computer-readable storage medium for girth weld risk estimation of transmission pipelines. Background technique [0002] After investigation, it is found that in recent years, oil and gas pipeline leakage and cracking accidents have mostly occurred due to the quality of girth welds. It can be seen that girth welds are the most common feature of oil and gas pipelines, and their safety determines the overall reliability of oil and gas pipelines. Once the girth weld cracking accident occurs, it will not only cause direct economic losses, but also damage the surrounding environment of oil and gas pipelines, and even cause casualties. Due to various reasons, girth welds will have different degrees of defects during the welding process. These defects are very easy to expand under the external load of the pipeline and t...
