Description

Technical Field

[0001] This invention belongs to the field of oil and gas pipeline networks, and particularly relates to a method, system, medium and equipment for periodic management of pipeline data. Background Technology

[0002] For over a decade, the development of integrity management in China has been limited by the level of GPS and GIS technology, leading pipeline companies to generally adopt data models based on linear reference relationships. This linear reference-based data model requires precise maintenance of the spatial logical relationships between the pipeline centerline and other facilities and surrounding environmental features. As data accumulates during operation, the difficulty of maintaining these relationships increases, along with the rising costs of operation and maintenance. Furthermore, this model cannot support data collection during the construction phase, hindering unified management of asset data throughout its entire lifecycle.

[0003] With the development and promotion of BeiDou satellite navigation and positioning services and geographic information technology in China, these two technologies have been widely applied in the pipeline industry, greatly reducing the reliance on linear reference relationships for pipeline integrity management. Meanwhile, with the advancement of digital transformation in state-owned enterprises, the demand for full lifecycle management of physical assets is increasing, and the implementation of enterprise data governance and other related work has enabled the interconnection of business systems. While the unification of data standards has achieved data uniformity at the semantic layer, the differences in models at different stages have become the biggest constraint and obstacle to the implementation of full lifecycle management of pipeline integrity. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method, system, medium and equipment for periodic management of pipeline data.

[0005] The technical solution of this invention to solve the above-mentioned technical problems is as follows: A method for periodic management of pipeline data, comprising:

[0006] Step 1: Based on the preset logical relationship of the line business object, associate the above-ground facility data of the pipeline with the pipeline data to form multiple sets of first association relationships;

[0007] Step 2: Using the corner pile in the above-ground facility data of any first association relationship as a reference, determine the location information of the circumferential weld in the pipeline data of the first association relationship, and associate any location information with the corner pile;

[0008] Step 3: Based on the preset risk rules, perform risk prediction for any circumferential weld corresponding to the corner pile, and obtain the risk prediction result for each circumferential weld;

[0009] Step 4: Determine the risk pipeline segment based on the risk prediction results of each circumferential weld. Perform maintenance on the risk pipeline segment according to the location information of the circumferential welds contained in the risk pipeline segment. When the maintenance result is scrap, generate a maintenance report based on the maintenance result.

[0010] The beneficial effects of this invention are: while meeting the needs of asset lifecycle management, by leveraging the application and promotion of domestically produced positioning and navigation technology and geographic information technology in the pipeline industry, the process of coordinate data participating in modeling is effectively changed by constructing logical relationships between pipeline business objects, eliminating the constraints of linear reference models on the development of the pipeline industry, and improving the comprehensiveness and accuracy of pipeline data management.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the logical relationships of the line service objects include: the logic of above-ground facility service objects and the logic of underground online facility service objects;

[0013] The process of obtaining the logic of the above-ground facility business object includes: classifying, encoding, and determining the hierarchical relationship of the surrounding geographical information of any pipeline segment determined based on the circumferential weld, wherein the surrounding geographical information includes the attribute information of the corner piles;

[0014] The process of acquiring the logic of the underground online facility business object includes: determining the core attributes of any circumferential weld, the core attributes including the circumferential weld number and the attribute information of the electronic pile corresponding to the corner pile.

[0015] Furthermore, the risk rules are specifically as follows:

[0016] Based on the hierarchical relationship of pipeline segments, threat elements are identified for any circumferential weld, and the category of threat elements is determined based on the identification results. Based on the category of threat elements, the risk of the circumferential weld is predicted.

[0017] Furthermore, the determination of risky pipeline segments based on the risk prediction results of each circumferential weld specifically involves:

[0018] The pipe features of the pipe segment within a preset distance are associated with the circumferential weld. Based on the risk rules, the pipe features corresponding to any circumferential weld are processed to obtain the risk value corresponding to any pipe feature of the circumferential weld. The risk value is used as the risk prediction result. The pipe segments with the same risk prediction result and the circumferential welds corresponding to the risk prediction results are identified as risk pipe segments.

[0019] Another technical solution of the present invention to solve the above-mentioned technical problems is as follows: A pipeline data periodic management system, comprising:

[0020] The first association module is used to: associate the above-ground facility data of the pipeline with the pipeline data based on the preset logical relationship of the line business object, and form multiple sets of first association relationships;

[0021] The second association module is used to: determine the location information of the circumferential weld in the pipeline data of any first association relationship based on the corner pile in the above-ground facility data; and associate any location information with the corner pile.

[0022] The prediction module is used to: perform risk prediction on any circumferential weld corresponding to the corner pile based on preset risk rules, and obtain the risk prediction result for each circumferential weld;

[0025] Furthermore, the logical relationships of the line service objects include: the logic of above-ground facility service objects and the logic of underground online facility service objects;

[0026] The process of obtaining the logic of the above-ground facility business object includes: classifying, encoding, and determining the hierarchical relationship of the surrounding geographical information of any pipeline segment determined based on the circumferential weld, wherein the surrounding geographical information includes the attribute information of the corner piles;

[0027] The process of acquiring the logic of the underground online facility business object includes: determining the core attributes of any circumferential weld, the core attributes including the circumferential weld number and the attribute information of the electronic pile corresponding to the corner pile.

[0028] Furthermore, the risk rules are specifically as follows:

[0029] Based on the hierarchical relationship of pipeline segments, threat elements are identified for any circumferential weld, and the category of threat elements is determined based on the identification results. Based on the category of threat elements, the risk of the circumferential weld is predicted.

[0030] Furthermore, the determination of risky pipeline segments based on the risk prediction results of each circumferential weld specifically involves:

[0031] The pipe features of the pipe segment within a preset distance are associated with the circumferential weld. Based on the risk rules, the pipe features corresponding to any circumferential weld are processed to obtain the risk value corresponding to any pipe feature of the circumferential weld. The risk value is used as the risk prediction result. The pipe segments with the same risk prediction result and the circumferential welds corresponding to the risk prediction results are identified as risk pipe segments.

[0032] Another technical solution of the present invention to solve the above-mentioned technical problems is as follows: a storage medium storing instructions, wherein when a computer reads the instructions, the computer executes the method described in any of the above-mentioned methods.

[0033] The beneficial effects of this invention are: while meeting the needs of asset lifecycle management, by leveraging the application and promotion of domestically produced positioning and navigation technology and geographic information technology in the pipeline industry, the process of coordinate data participating in modeling is effectively changed by constructing logical relationships between pipeline business objects, eliminating the constraints of linear reference models on the development of the pipeline industry, and improving the comprehensiveness and accuracy of pipeline data management.

[0034] Another technical solution of the present invention to solve the above-mentioned technical problems is as follows: an electronic device, including the above-mentioned storage medium and a processor that executes the instructions in the above-mentioned storage medium.

[0035] The beneficial effects of this invention are: while meeting the needs of asset lifecycle management, by leveraging the application and promotion of domestically produced positioning and navigation technology and geographic information technology in the pipeline industry, the process of coordinate data participating in modeling is effectively changed by constructing logical relationships between pipeline business objects, eliminating the constraints of linear reference models on the development of the pipeline industry, and improving the comprehensiveness and accuracy of pipeline data management.

[0042] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0043] like Figure 1 As shown, a pipeline data periodic management method includes:

[0044] Step 1: Based on the preset logical relationship of the line business object, associate the above-ground facility data of the pipeline with the pipeline data to form multiple sets of first association relationships;

[0045] Step 2: Using the corner pile in the above-ground facility data of any first association relationship as a reference, determine the location information of the circumferential weld in the pipeline data of the first association relationship, and associate any location information with the corner pile;

[0046] Step 3: Based on the preset risk rules, perform risk prediction for any circumferential weld corresponding to the corner pile, and obtain the risk prediction result for each circumferential weld;

[0047] Step 4: Determine the risk pipeline segment based on the risk prediction results of each circumferential weld. Perform maintenance on the risk pipeline segment according to the location information of the circumferential welds contained in the risk pipeline segment. When the maintenance result is scrap, generate a maintenance report based on the maintenance result.

[0048] In some possible implementations, while meeting the needs of full lifecycle asset management, the application and promotion of domestically produced positioning and navigation technologies and geographic information technologies in the pipeline industry can effectively change the process of coordinate data participating in modeling by constructing logical relationships between pipeline business objects, thereby eliminating the constraints of linear reference models on the development of the pipeline industry and improving the comprehensiveness and accuracy of pipeline data management.

[0049] It should be noted that pipeline data includes the location of the pipeline, the location information of the circumferential welds within the pipeline, etc. The logical relationships of the line business objects include: the logic of above-ground facility business objects and the logic of underground online facility business objects. Specifically:

[0050] like Figure 3As shown, the geographic information elements, including pipeline surface ancillary facilities (including three piles), surrounding human and natural environmental elements, and social supporting resources, are classified and coded according to the Geographic Information Classification and Coding Rules (GB / T25529-2010). (Note: In the surveying and mapping industry, each type of object is referred to as an element. Elements related to pipeline facilities and their surrounding environment are classified and coded according to GB / T25529, but underground pipeline facilities are not.)

[0051] For pipeline business elements (in addition to being classified and coded according to national standards for spatial location management, pipeline business elements also need to establish business logic relationships according to pipeline industry needs, i.e., hierarchical relationships between assets), besides being classified and coded according to geographic information element management, it is necessary to maintain the hierarchical (asset hierarchy refers to the fact that a station is the parent element of a valve chamber, a valve chamber is the parent element of a corner pile, etc. Therefore, the assets here include not only pipelines separated by welds, but also assets such as stations, valve chambers, corner piles, and hydraulic structures) attribution relationships.

[0052] Table 1. Logical Relationships of Typical Business Objects for Pipeline Above-Ground Facilities

[0053] GIS Element type Classification code Identification code Parent element identifier code name coordinate point station ZC LYZ <Pipeline to which it belongs> Optional Required point Valve chamber FS FS01 LYS Optional Required point Corner stakes ZJZ AB001 FS01 Optional Required point Hydraulic engineering WI WI01 AB001 Optional Required Wire the way DL R01 Not involved Optional Required noodle residential area JMD JMD01 Not involved Optional Required noodle Highly corrosive soil TR TR01 Not involved Optional Required

[0054] The logic for the underground online facility business object is established as follows:

[0055] Corner stakes in above-ground facilities are managed as geographic information elements, with core attributes including identification codes and the valve chamber to which they belong; the required attribute is coordinates. Corner stakes can be physical stakes on-site or virtual electronic stakes set up as positioning references.

[0056] Circumferential welds are managed as non-geographic information elements. The core attributes are the circumferential weld number and the corresponding corner stake / virtual electronic stake. The required attribute is the offset distance. Defects and sleeves are not managed as elements but as attributes. The core attribute is the corresponding circumferential weld number, and the required attribute is the offset distance.

[0057] Table 2. Logical Relationships of Typical Business Objects for Above-Ground and Underground Pipeline Online Facilities

[0058]

[0059] Step 3, based on preset risk rules, performs risk prediction for any circumferential weld corresponding to the corner pile, and the specific process for obtaining the risk prediction result for each circumferential weld is as follows:

[0060] (1) Asset initialization

[0061] Asset initialization refers to the process of creating and initializing the attributes of an asset during the construction phase through management activities such as design and construction, and the process of restoring the asset attributes to the production state during the operation phase through management activities such as asset upgrading, renovation, and major repairs.

[0062] Before the design activity, relevant attributes of surface facilities such as roads, residential areas, and highly corrosive soils were collected for the preliminary planned pipeline route (the area through which the pipeline passes). ， This information is used in the design phase to assess whether the route is reasonable (e.g., the pipeline should avoid residential areas and reduce road intersections), and in the operation phase to calculate the risks faced by the pipeline (e.g., residential areas and roads are used to assess the consequences of pipeline failure, and the corrosivity of highly corrosive soil is used to calculate the risk of pipeline corrosion).

[0063] During the design phase, the above-ground facilities of pipelines such as stations, valve chambers, corner piles, and hydraulic structures, as well as the surrounding environmental facilities such as roads and residential areas, are assigned values ​​such as element type, classification code, identification code, and name according to industry classification and coding standards, and the relationship between objects is established according to the preset regulations.

[0064] During the construction phase, using the corner pile as a reference, the circumferential weld is associated with the corner pile by recording the correspondence between the circumferential weld and its nearest corner pile, as well as the distance of the circumferential weld from the corner pile. The circumferential weld is then positioned through this association.

[0065] By associating pipe features such as sleeves and steel pipes with their nearest circumferential welds and recording the distance between the sleeves, steel pipes, etc. and their nearest circumferential welds, the association and positioning of pipe features can be achieved.

[0066] (2) Asset Operation Stage

[0067] The asset operation phase is also the phase of pipeline performance degradation. During operation, the asset is affected by both the natural environment (such as soil corrosion and geological disasters) and the human environment (damage from third-party construction, drilling for oil and gas theft, and terrorist activities), causing its performance to decline continuously. On the other hand, asset managers prevent accidental damage to the asset through maintenance and repair activities, such as preventing accidental damage caused by third-party construction through supervision, or slowing down the rate of asset performance degradation, such as adding cathodic protection facilities to reduce and decrease the corrosion rate.

[0068] Risk identification identifies elements that threaten the integrity of assets. These elements include activities and environmental entities that have a potential threat to the asset's performance degradation, i.e., damaging activities and environmental entities.

[0069] These entities are categorized into risk factors based on their impact on assets: on-site risk factors, geological disaster risk factors, third-party damage risk factors, and accident consequence risk factors.

[0070] For each type of risk factor, research and formulate the impact of the risk factor on the asset and the impact of asset failure on the surrounding area, forming risk rules. For example, the impact of corrosive soil on asset corrosion, and the impact of different construction methods (manual excavation or mechanical excavation) on the asset when pipelines are damaged.

[0071] Step 4: Based on the risk prediction results of each circumferential weld, determine the risky pipeline segment. According to the location information of the circumferential welds contained in the risky pipeline segment, perform maintenance on the risky pipeline segment. When the maintenance result is scrapping, the specific process of generating a maintenance report based on the maintenance result is as follows:

[0072] By using GIS tools to match assets within the scope of each damage-related activity and environmental entity, the process involves first analyzing corner piles within the scope of the activity, then retrieving the associated circumferential welds from the corner piles, and finally retrieving the associated pipeline features from the circumferential welds. This process enables the identification of circumferential welds and pipeline features within the scope of the activity.

[0073] Risk rules are used to calculate the performance degradation impact on each risk feature, and the overall asset features' ability to resist performance degradation is combined to calculate the risk value of each pipeline feature. For example, the pipeline's ability to withstand external loads is calculated based on its diameter, wall thickness, material, and defects. The probability of pipeline failure is calculated by combining the external loads added to the pipeline by the surrounding soil settlement. Furthermore, the potential environmental pollution consequences of pipeline failure are calculated based on the presence of rivers or water bodies around the pipeline.

[0074] Continuous pipelines with similar damage factors and risk values ​​are grouped into the same risk segment, and detection and maintenance plans are developed based on the risk characteristics of each segment. Detection plans include internal and external inspection plans for assets in highly corrosive environments; regular manual patrol plans for potential third-party damage activities; pre-flood and post-training inspection plans, pre-rain and post-rain patrol plans, and geological disaster monitoring activities for areas prone to geological disasters; and the investigation and dynamic maintenance of emergency resources and supplies around pipelines in response to leaks or geological disaster threats.

[0075] The asset status is assessed based on the detection parameters, and maintenance, repair, and upgrading measures are formulated. For repair tasks that can directly provide coordinate information during detection activities, the coordinates are used to guide repair personnel. For example, third-party damage activities discovered during pipeline patrols can directly provide the activity location to other management personnel and provide navigation for subsequent handling personnel. For repair tasks that cannot provide coordinate information, the coordinates are calculated using the business logic relationships in Part 1, and navigation is then performed. For example, if internal inspection provides information on pipeline defects, the mileage of the defect is used as the positioning reference. The location information of the defect needs to be obtained through the circumferential welds associated with the defect and the corner stakes associated with the circumferential welds.

[0076] (3) Asset scrapping stage

[0077] When an asset's performance degrades to a certain extent and reaches the standard for scrapping, the asset is scrapped entirely or partially. The scrapped asset section, focusing on circumferential welds and pipeline characteristics, has its initialization data, performance degradation process data, related detection records, and maintenance records compiled and archived as historical reference data for future construction and maintenance management of similar assets.

[0078] This invention achieves full lifecycle quality control and process management of data assets for business objects. Compared with existing technologies, this invention has the following significant advantages:

[0079] (1) This method can cover the management of all asset entities such as lines and stations, effectively improving the problem that lines and stations cannot use the same data model.

[0080] (2) The method is applicable to the management stages of design, procurement, construction, and operation, and meets the management needs of digital transformation and data governance throughout the entire life cycle.

[0081] (3) The method maintains data through the logical relationship between asset entities and asset entity sets, and can model without spatial location attributes, thereby avoiding the adverse effects of linear reference maintenance.

[0082] The entire lifecycle of pipeline assets is divided into four stages: design, construction, operation, and decommissioning. Among these, design and construction belong to the creation category of activities. Through creation activities, the various attributes of the pipeline asset (such as pipe wall thickness, material, pressure bearing capacity, etc.) are initialized.

[0083] Once a pipeline enters the operational phase, its performance degrades due to the impacts of both the surrounding natural environment (such as soil and water conditions) and the social environment (such as damage from third-party construction). Simultaneously, pipeline companies mitigate accidental damage and slow the rate of degradation through maintenance and repair activities. These include timely detection of third-party damage events during pipeline patrols to prevent further damage, and reducing corrosion through anti-corrosion coating maintenance. Therefore, during operation, pipelines are affected by two main factors: performance degradation due to environmental and damaging activities, and mitigation of accidental damage and the rate of performance degradation through maintenance and repair activities.

[0084] Throughout the operational period, pipeline performance generally tends towards degradation. To prevent failures due to performance degradation, continuous monitoring of pipeline performance, environmental factors and activities affecting pipeline performance, and the resources required for pipeline maintenance are essential during the operational phase. This allows for real-time monitoring of pipeline performance status and the patterns of performance degradation within the asset's environment. Monitoring activities include routine inspections, video surveillance, fiber optic early warning systems to detect third-party damage, internal and external inspections to detect pipeline corrosion and other defects, and assessments of pressure-bearing capacity based on these inspections.

[0085] When pipeline performance degrades to an unacceptable level, severely degraded pipeline assets should be maintained (including defect repair and pipe replacement) to restore their performance to their design state, thus re-initializing the pipeline asset. When performance degrades to the point where the pipeline is deemed unusable, it should be scrapped.

[0086] I. Abstraction of Business Concepts

[0087] By abstracting the above business processes, the concepts can be categorized into three objects: activities, rules, and entities. Activities refer to various behaviors that act on entities according to certain rules, including: creation activities, maintenance activities, detection activities, improvement activities, and damage activities. Rules refer to the norms or laws followed when activities interact with entities, and between entities themselves, including activity rules (such as safety behavior guidelines, business processes, etc.) and risk rules (such as the corrosive effects of corrosive environments on pipelines). Entities refer to the business objects of pipeline integrity management, including asset entities, environmental entities, and resource entities. Details are as follows:

[0088] 1) Events

[0089] Creation activities refer to the management behaviors of instantiating business asset entities and initializing their attributes, including activities such as design, procurement, construction, and pipeline replacement.

[0090] Maintenance activities refer to management actions taken to maintain the integrity of physical assets and prevent asset performance degradation, including activities such as corrosion prevention, cleaning, and routine maintenance.

[0091] Detection activities refer to management actions taken to obtain information about the integrity attributes or status of assets. These include the detection of physical assets, as well as the detection of environmental entities and damage-related activities.

[0092] Improvement activities refer to management actions implemented to enhance the integrity and performance of assets to reach or approach design values, including repair, renovation, and emergency repairs.

[0093] Damaging activities refer to actions carried out by third parties that may negatively impact the integrity of the pipeline, including third-party construction, encroachment, and oil and gas theft.

[0094] 2) Rule Class

[0095] Activity rules refer to the behavioral guidelines that must be followed during the implementation of an activity. These include the behavioral norms that the activity itself must follow, such as safety behavioral guidelines and business processes, as well as the rules for the applicable objects of the activity and changes in corresponding attribute values.

[0096] Risk rules refer to the laws governing the interactions between environmental entities and asset entities, as well as among asset entities themselves. These include the consequences of asset entities acting on surrounding environmental entities, and the failures caused by surrounding environmental entities and other asset entities acting on asset entities.

[0097] 3) Entity Class

[0098] An asset entity refers to the smallest physical unit with a unique identifier that performs a function or auxiliary function in the transportation and storage of oil and gas media. This includes entities responsible for the integrity management of station equipment and facilities, lines, ground markings, construction facilities, and other similar entities.

[0099] An asset entity set refers to a collection of multiple asset entities formed after they are grouped together according to certain business rules, including stations, valve chambers, (electronic) piles, equipment sets, pipeline sections, etc.

[0100] Environmental entities refer to entities in the social and human environment surrounding a pipeline that pose a hazard to the pipeline or whose operation poses a hazard to it, including corrosive soil, unstable mountains, and sensitive receptors.

[0101] Resource entities refer to the resources involved in asset integrity management activities, including: enterprise resources such as spare parts, emergency supplies, and relevant skilled personnel, as well as social resources such as hospitals, fire brigades, and material supply units.

[0102] II. Description of Business Logic Relationships

[0103] Using abstract business concepts to express the relationships between various elements, such as Figure 5 As shown.

[0104] With the asset entity at its core, integrity management activities can be abstracted into three activity clusters: object initialization, performance degradation, and performance assessment. The asset entity undergoes attribute initialization through creation activities, and its performance (such as wall thinning and reduced pressure bearing capacity) continuously declines under the combined influence of damage-related activities (e.g., third-party construction activities), environmental entities (e.g., corrosive soil environments), and maintenance activities (e.g., reducing the frequency of pipeline damage from third-party construction activities through pipeline patrols, and ensuring pipelines are protected from corrosion through cathodic protection systems). (Damage-related activities and environmental entities act as risk factors, contributing to pipeline performance degradation, while maintenance activities mitigate and reduce the negative impact of these hazards on the pipeline). During this period, detection activities continuously acquire asset object attributes and the threat status they face (detecting asset object attributes includes obtaining information on pipeline wall thinning through internal inspection, and detecting the threat status of the pipeline includes discovering construction and encroachment directly above the pipeline through pipeline patrols) to determine the risks faced by the asset entity. When the risk reaches a certain level, the asset's attributes are reinitialized through improvement activities, thus initiating a new cycle of asset management until the asset loses its maintenance value (the industry standard is that when the cost of restoring asset performance exceeds the cost of rebuilding the asset, it loses its maintenance value; our organization is currently applying for ISO standard for this criterion), and enters the scrapping stage. During this process, all activities follow the following rules:

[0105] (1) Creation activities create asset entities and initialize the attributes of asset entities. Except for creation activities, other activities may not create asset entities.

[0106] (2) Improvement activities have the authority to change the attribute values ​​of asset entities, and the scope of the changes is between the current value and the design value of the asset entity. Improvement activities can create and initialize ancillary facility asset entities. For example, by creating hydraulic protection facilities, the impact of external additional stress on pipeline assets located in geological disaster areas can be reduced, thereby improving the external stress environment faced by the pipeline.

[0107] (3) The relationship between damage-related activities and environmental entities and the asset entity (the relationship between corrosive soil and pipeline corrosion) and the type of action (referring to the failure type, i.e., perforation rather than rupture under corrosion) is determined through risk rules. Risk rules can change the asset entity's attributes (pressure bearing capacity, wall thickness, etc.) by altering the attributes of damage-related activities and environmental entities, but cannot directly change the asset entity's attributes. Third-party activities and corrosive soil have negative impacts on the asset. Different damage-related activities and environmental entities will have different impacts on the asset (for example, third-party activities may directly lead to pipeline leakage, while corrosive soil will thin the pipeline through long-term corrosion, eventually leading to pipeline perforation and leakage). The model for quantifying these negative impacts is the risk rule. After quantifying the attributes of the damage-related activities and environmental entities faced by the pipeline, and using them as inputs to the risk rule, the trend of performance attribute decline of the pipeline asset under the influence of these factors can be obtained.

[0108] (4) Detection activities target asset entities, environmental entities associated with the asset entities, and damage-related activities. Detection activities can directly modify the attribute values ​​of asset entities (such as wall thickness, pressure bearing capacity, etc. For example, the current wall thickness of a pipeline can be directly obtained through internal and external detection, and the pressure bearing capacity can be assessed through integrity evaluation based on the detection results), or modify the attribute values ​​of asset entities by modifying the attributes of environmental entities and damage-related activities.

[0109] It should be noted that improvement-related assets are restored to their designed state by changing asset attributes, such as replacing severely corroded pipes; while detection-related assets are detected by instruments, such as obtaining pipe wall thickness information through internal inspection, thereby correcting the asset attribute information in the database.

[0110] III. Abstract Classes and Typical Entity Classes

[0111] Abstract classes and entity classes are objects instantiated from business logic that can be used in information system development. The business logic relationships in Part II are a series of concepts abstracted from business, while this part concretizes these concepts into objects and methods that can be used in information system development.

[0112] The abstract class and the concrete class of the line service object in this storage method are as follows: Figure 6 As shown.

[0113] Preferably, in any of the above embodiments, the line service object logic includes: above-ground facility service object logic and underground online facility service object logic;

[0114] The above-ground facility business object logic specifically involves: classifying, encoding, and determining the hierarchical relationship of the surrounding geographical information of any pipeline segment determined based on the circumferential weld, wherein the surrounding geographical information includes the attribute information of corner piles;

[0115] The specific logic of the underground online facility business object is as follows: determine the core attributes of any circumferential weld, the core attributes including the circumferential weld number and the attribute information of the electronic pile corresponding to the corner pile.

[0116] Appendix Figure 3 The document outlines the main above-ground facilities involved in pipeline assets, including stations (LYZ), valve chambers (FS01), corner piles (AB001), hydraulic works (WI01), and pipelines (curves between stations, valve chambers, corner piles, and hydraulic works), as well as surrounding natural and socio-cultural environmental facilities such as roads (R01), corrosive soils (TR01), and residential areas (JMD01). The management of surrounding natural and socio-cultural environmental facilities follows GB / T25529 classification and coding, and is managed as geographic information elements in the database. In addition to being managed as geographic information elements, pipeline assets also require further management. Figure 4 Establish asset hierarchy relationships for underground facilities.

[0117] Figure 4 The diagram illustrates the relationship between corner piles, circumferential welds, and pipe sections. It serves to help understand how to manage underground circumferential welds using above-ground corner piles. This is a supplementary diagram illustrating the relationships shown in Table 2.

[0118] Figure 6 Based on Figure 5 The business logic relationships shown are based on a conceptual data model developed using the third paradigm. Explained with assets at the core, assets include all objects from pipelines to welds. These objects establish one-to-many relationships through business hierarchy; for example, a pipeline contains multiple stations, a station contains multiple valve chambers, and so on. Common attributes and methods of objects such as pipelines and stations are defined in the asset objects, and these sub-elements can inherit these methods and attributes. Assets are constrained by two rules: first, activity-based sub-elements (creation, maintenance, damage, detection, improvement) act on assets under activity rules (including system documents, operating procedures, etc.); second, environmental entities (corrosive environments, disaster-prone areas) affect assets under risk rules (corrosion models, disaster models, etc.). Furthermore, corresponding relationships need to be established between the tools and equipment used in activities and the spare parts required by the assets. Note: Damage-related activities are constrained by risk rules in the business logic abstraction, but are constrained by activity rules in the conceptual model. This is mainly because damage-related activities are risk factors from a business logic perspective, but from an information technology development perspective, their rules are more similar to business activities, so the adjustment was made. The two are not in conflict.

[0119] Preferably, in any of the above embodiments, the risk rule specifically refers to:

[0120] Based on the hierarchical relationship of pipeline segments, threat elements are identified for any circumferential weld, and the category of threat elements is determined based on the identification results. Based on the category of threat elements, the risk of the circumferential weld is predicted.

[0121] Preferably, in any of the above embodiments, determining the risky pipeline segment based on the risk prediction results of each circumferential weld specifically involves:

[0122] The pipe features of the pipe segment within a preset distance are associated with the circumferential weld.

The pipe segments with the same risk prediction result and the circumferential welds corresponding to the risk prediction results are identified as risk pipe segments.

[0128] In some possible implementations, while meeting the needs of full lifecycle asset management, the application and promotion of domestically produced positioning and navigation technologies and geographic information technologies in the pipeline industry can effectively change the process of coordinate data participating in modeling by constructing logical relationships between pipeline business objects, thereby eliminating the constraints of linear reference models on the development of the pipeline industry and improving the comprehensiveness and accuracy of pipeline data management.
