Description

Technical Field

[0001] This invention relates to the field of information and communication technology, and in particular to a method and system for inter-system data sharing based on industrial internet identifier resolution. Background Technology

[0002] For different business areas, companies typically build different information systems, such as supply chain management systems, ERP systems, and project management systems. Supply chain management systems are responsible for managing supply chain-related tasks; ERP systems are responsible for planning procurement, production, cost, inventory, and human resources; and project management systems are responsible for managing engineering and construction-related tasks. However, as business progresses, these systems become interdependent in terms of data, requiring data sharing through interface connections. But the following problems often arise during data sharing:

[0003] 1) The problem of inconsistent encoding for the same entity in different systems, specifically:

[0004] In the early stages of system construction and use, due to the lack of unified planning, the same entity assets in different systems had inconsistent coding, which increased the difficulty of data connection.

[0005] 2) There is a nesting problem in the encoding dimensions of entities in different systems, specifically:

[0006] Different systems have different responsibilities and different dimensions of managing physical assets, resulting in nested identification codes between systems and making data association difficult.

[0007] 3) Data sharing issues with upstream and downstream enterprises in the industry, specifically:

[0008] Traditional information technology has played a significant role in data sharing within enterprises, but at the industry level, due to limitations in technology, standards, and norms, information silos are common, making data sharing across industries difficult. Summary of the Invention

[0012] Based on industrial internet identifier resolution technology, data from upstream and downstream enterprises in the enterprise's industry can be connected.

[0013] Once the data of upstream and downstream enterprises in the same industry are connected, an enterprise service bus based on identifier resolution is constructed based on the positive mapping relationship and using identifier mapping, heterogeneous identifier recognition and heterogeneous identifier resolution technologies.

[0025] 2) Secondly, the present invention also provides an inter-system data sharing system based on industrial internet identifier resolution, the specific technical solution of which is as follows:

[0026] This includes a generation module, a connection module, and a building module;

[0052] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0053] like Figure 1As shown in the figure, an inter-system data sharing method based on industrial internet identifier resolution according to an embodiment of the present invention includes the following steps:

[0054] S1. Generate an Industrial Internet identifier for each entity in each system within the enterprise, and establish a positive mapping relationship between the Industrial Internet identifier of each entity and the private identifier of each entity.

[0055] The Industrial Internet Identifier Resolution System and Identifier Resolution Process are explained as follows:

[0056] 1) Industrial Internet Identifier Resolution System:

[0057] As a crucial component of the industrial internet network architecture, the industrial internet identifier resolution system is equivalent to the domain name resolution system (DNS) in the internet domain. It is one of the core infrastructures of the industrial internet, and its core consists of two parts: identifier coding and the resolution system. The identifier coding serves as a unique "identity card" for machines, items, and digital objects; the resolution system utilizes the identifier to uniquely locate and query information about machines, items, and digital objects.

[0058] 2) Identifier resolution process, such as Figure 2 As shown, the details are as follows:

[0059] S1001, The identification application sends an identification resolution request to the recursive resolution node to obtain the identification information;

[0060] S1002. The recursive parsing node sends an identifier resolution request to the root node to obtain the information of the first-level node to which the identifier belongs.

[0061] S1003. The root node accepts and responds to the identifier resolution request sent by the recursive resolution node, retrieves the corresponding first-level node for the identifier by querying the registration information, and returns the first-level node information to the recursive resolution node.

[0062] S1004. The recursive parsing node sends an identifier resolution request to the first-level node to obtain the information of the second-level node to which the identifier belongs.

[0063] S1005. The first-level node accepts and responds to the identifier resolution request sent by the recursive resolution node, retrieves the second-level node that responded with the prefix by querying the registration information, and returns the second-level node information to the recursive resolution node.

[0064] S1006. The recursive parsing node sends an identifier resolution request to the secondary node to obtain the information of the tertiary node to which the identifier belongs.

[0065] S1007. The secondary node accepts and responds to the identifier resolution request sent by the recursive resolution node, retrieves the tertiary node that responded with the prefix by querying the registration information, and returns the tertiary node information to the recursive resolution node.

[0066] S1008. The recursive parsing node sends an identifier resolution request to the third-level node to obtain the resolution result.

[0067] S1009, the third-level node is responsible for receiving and responding to the identifier resolution request sent by the recursive resolution node, retrieving the value set corresponding to the identifier by querying the local database, and returning the resolution result to the recursive resolution node;

[0068] S1010, the recursive parsing node returns the parsing result to the identifier application. The parsing result can be the value set corresponding to the identifier, or it can be the information of the third-level node to which the identifier belongs;

[0069] S1011. When the resolution result obtained by the identification application from the recursive resolution node is the information of the third-level node to which the identification belongs, the identification application directly sends an identification resolution request to the third-level node to which the identification belongs in order to obtain the identification information.

[0070] S1012. The third-level node to which the identifier belongs is responsible for accepting and responding to the identifier resolution request. It retrieves the value set corresponding to the identifier by querying the local database and returns the resolution result to the identifier application.

[0071] S1008 to S1009 are optional steps, and S1011 to S1012 are optional steps.

[0072] S2. Based on industrial internet identifier resolution technology, connect the data of upstream and downstream enterprises in the enterprise's industry;

[0073] The data flow between upstream and downstream enterprises in a company's industry, achieved through Industrial Internet identifier resolution technology, is described as follows:

[0074] Upstream enterprises assign industrial internet identification codes to identified entities (which can be physical entities such as products, or virtual entities such as processes or design schemes), collect relevant attribute information of the identified entities, and register them to the identification resolution system software through the identification registration process;

[0075] After obtaining the identified entity, downstream enterprises can use the identification code corresponding to the product and rely on the aforementioned industrial internet identification resolution process to obtain the relevant attribute information of the entity from the identification resolution system, thereby achieving the goal of connecting the data of upstream and downstream enterprises in the enterprise's industry through industrial internet identification resolution technology.

[0076] S3. After connecting the data of upstream and downstream enterprises in the same industry, based on the positive mapping relationship and using identifier mapping, heterogeneous identifier recognition and heterogeneous identifier resolution technologies, an enterprise service bus based on identifier resolution is constructed. The enterprise service bus based on identifier resolution is used to provide data sharing services.

[0077] Optionally, the above technical solution also includes:

[0078] S4. Based on the caching service, establish a reverse mapping relationship between the private identifier of each entity and the industrial internet identifier of each entity;

[0079] Reverse mapping is also a type of mapping, except that the roles of the mapping party and the mapped party are reversed. The purpose of introducing forward and reverse mappings is to find the corresponding public identifier through reverse mapping and to find the corresponding other private identifiers through forward mapping. (See diagram below.) Figure 3 As shown.

[0080] S5. Integrate forward and reverse mapping relationships to achieve retrieval and query. Specifically, integrate forward and reverse mapping relationships to achieve retrieval and query of private identifiers through industrial internet identifiers to other private identifiers.

[0081] Different information systems within an enterprise assign different codes to the same entity. While linking private identifiers through industrial internet identifiers, efficient identifier mapping is limited by the number of database indexes. Therefore, this invention proposes a query efficiency improvement scheme based on redundant storage, namely S4 to S5, which overcomes the limitation on the number of database indexes. Specifically:

[0082] Maintain a forward mapping relationship between Industrial Internet identifiers and private identifiers of various systems in the database, and add a unique index to the Industrial Internet identifier field; based on a caching service, maintain a reverse mapping relationship between private identifiers and Industrial Internet identifiers, where the caching service can be a Redis caching service; combining the forward and reverse mapping relationships between Industrial Internet identifiers and private identifiers, realize fast retrieval and querying from private identifiers to Industrial Internet identifiers to other private identifiers, such as... Figure 3 As shown.

[0083] Optionally, the above technical solution also includes:

[0084] S6. Assign a different identifier prefix to each system within the enterprise, merge the identifier prefix corresponding to any system with the system's private identifier to generate a new identifier for that system, and repeat this process until a new identifier for each system is obtained. Specifically, the fusion process involves concatenating the identifier prefix corresponding to any system with the system's private identifier using string concatenation to obtain a new identifier for that system.

[0085] There is a possibility of conflicts between private identifiers in different enterprise systems. To avoid data chaos caused by identifier conflicts, it is necessary to introduce a private identifier anti-conflict mechanism, namely S6. This mechanism employs a private identifier anti-conflict strategy based on identifier prefixes. Specific identifier prefixes are assigned to different systems, and the identifier prefixes and system private identifiers are merged to generate new identifiers. This resolves the problem of private identifier conflicts between different systems and avoids identifier conflicts between them. Figure 4 As shown, the new identifier of the system consists of an identifier prefix and a private identifier, and the specific implementation method is string concatenation.

[0086] Optionally, the above technical solution also includes:

[0087] S7. Construct the attribute data template corresponding to the entity;

[0088] S8. Aggregate and organize the data from each system within the enterprise, identify the entities in each system, obtain the attributes corresponding to each entity and populate them into the attribute data template, and obtain the identifier data containing the private identifier for each entity.

[0089] In another embodiment, such as Figure 5 As shown, it includes:

[0090] 1) Identifier resolution secondary node platform:

[0091] The software platform for the secondary node of the oil and gas storage and transportation industry identifier resolution, built on the identifier resolution system, supports the functions of identifier registration, identifier resolution, and identifier query for oil and gas storage and transportation industry identifier data.

[0092] 2) Identifier Resolution Enterprise Service Bus:

[0093] It mainly implements functions such as identifier mapping, interface mapping, and data governance, and supports functions such as data synchronization and data services based on identifier resolution.

[0094] 3) Unified system construction and quick-win projects:

[0095] The system leverages the Enterprise Service Bus (ESB) for identifier resolution to aggregate and provide data services for the group's existing unified construction systems and QuickWin projects. Based on the ESB, the unified construction systems and QuickWin projects utilize common data service interfaces to achieve data interoperability between different systems within the group.

[0096] 4) Upstream and downstream enterprises:

[0097] Interconnection and interoperability of upstream and downstream data in the industry can be achieved through identifier resolution nodes.

[0098] The principle is described in detail below:

[0099] 1) Data aggregation:

[0100] Through API interfaces and data aggregation toolsets, the group's existing systems and upstream and downstream industry data are aggregated using API interfaces, data lakes, data platforms, databases, tables, and other formats.

[0101] 2) Identifier Mapping:

[0102] Based on the Enterprise Service Bus, an identifier mapping module is built to enable association between different identifiers of the same entity, such as... Figure 6 As shown.

[0103] Figure 6 The content shown illustrates another type of image identification relationship involving forward and reverse mapping. In the Enterprise Service Center, based on the identification data registration, public identifiers are associated with existing private identifiers in the system to establish a forward mapping relationship. Simultaneously, a reverse mapping relationship from private identifiers to public identifiers is maintained. See S5 for a detailed implementation plan.

[0104] 3) Data services:

[0105] Based on the general API interface for identifier resolution, and on the basis of identifier mapping, it supports the data docking needs of systems within the group.

[0106] In another embodiment, the following steps are included:

[0107] S101. Identify industry entities and compile industrial internet identification coding rules and attribute data templates for these entities;

[0108] S102. Based on the attribute data template, use technical means (interface integration, database synchronization, etc.) to realize the identification and registration of industry entity attribute data;

[0109] S103. Modify the private identifiers in the system to prevent conflicts;

[0110] S104. Employ strategies such as redundant storage to map the codes of the same entity in different systems within the enterprise to the industrial internet identification codes of the entity, and establish a relationship.

[0111] S105. Refer to the open interface of the secondary node platform for identifier resolution to implement the identifier registration, identifier resolution, and identifier query interfaces;

[0112] S106. Other applications rely on the above interfaces to implement data query services based on private identifiers.

[0113] Enterprise system A accesses the identifier resolution enterprise service bus through its internal private identifier. Relying on the identifier mapping module, and through the reverse and forward mapping relationships between identifiers (details in S5), it obtains the private identifier of system B. Then, it uses system B's private identifier combined with the identifier resolution logic to obtain the corresponding identifier data, such as... Figure 7As shown.

[0114] The technical effects of this invention are as follows:

[0115] 1) To address the issues of inconsistent and nested coding among enterprise systems, an enterprise service bus based on identifier resolution is proposed. By relying on technologies such as identifier mapping, heterogeneous identifier recognition, and heterogeneous identifier resolution, data can be connected and linked between different systems within the enterprise, thus solving the problem of inconsistent and nested coding of the same entities in different systems.

[0116] 2) To address the data silo problem commonly found among upstream and downstream enterprises in the industry, a proposal is made to leverage the enterprise service bus based on industrial internet identifier resolution to connect data between upstream and downstream enterprises, thereby achieving data sharing.

[0117] 3) To address the query efficiency problem in the invention, a query efficiency improvement scheme based on redundant storage is proposed, which breaks the limitation on the number of database indexes and optimizes query efficiency.

[0118] 4) To address the issue of private identifier conflicts in different systems, a solution for resolving identifier conflicts is proposed to avoid such conflicts and thus resolve the private identifier conflict problem.

[0119] 5) Reduced integration difficulty: Based on this invention, data aggregation within an enterprise is achieved through an identifier resolution platform. General data services for third-party applications are realized through standard identifier resolution API interfaces, avoiding direct integration between systems, reducing system development time costs, and improving development efficiency.

[0120] 6) Improve data quality: Data template management is achieved based on industry metadata in the identifier resolution system. Data cleaning is achieved by combining loading, transformation and extraction techniques on the basis of data templates, thereby improving data quality.

[0121] 7) Expand the scope of data services: Combine the identifier resolution system to connect upstream and downstream data in the industry and build industry data service capabilities based on identifier resolution.

[0122] 8) Reduce integration costs: Based on this invention, the association between heterogeneous codes of different systems is realized through the identifier mapping mechanism, avoiding the need for third-party applications to directly maintain the mapping between identifiers, and realizing the effect of calling other service data based on local encoding.

A method for inter-system data sharing based on Industrial Internet identifier resolution, characterized in that, include: Generate an Industrial Internet identifier for each entity in each system within the enterprise, and establish a positive mapping relationship between the Industrial Internet identifier of each entity and the private identifier of each entity. Based on industrial internet identifier resolution technology, data from upstream and downstream enterprises in the enterprise's industry can be connected. Once the data of upstream and downstream enterprises in the same industry are connected, based on the positive mapping relationship and using identifier mapping, heterogeneous identifier recognition and heterogeneous identifier resolution technologies, an enterprise service bus based on identifier resolution is constructed. The enterprise service bus based on identifier resolution is used to provide data sharing services. The identifier resolution process includes: The identification application sends an identification resolution request to the recursive resolution node to obtain the identification information; The recursive parsing node sends an identifier resolution request to the root node to obtain information about the first-level node to which the identifier belongs; The root node accepts and responds to the identifier resolution request sent by the recursive resolution node, retrieves the corresponding first-level node for the identifier by querying the registration information, and returns the first-level node information to the recursive resolution node; The recursive resolution node sends an identifier resolution request to the first-level node to obtain information about the second-level node to which the identifier belongs; The first-level node accepts and responds to the identifier resolution request sent by the recursive resolution node, retrieves the second-level node with the prefix response by querying the registration information, and returns the second-level node information to the recursive resolution node; The recursive resolution node sends an identifier resolution request to the second-level node to obtain the information of the third-level node to which the identifier belongs; Second-level nodes accept and respond to identifier resolution requests sent by recursive resolution nodes, retrieve the third-level nodes that respond with the prefix by querying registration information, and return the third-level node information to the recursive resolution nodes; The recursive parsing node sends an identifier resolution request to the third-level node to obtain the resolution result; The third-level node is responsible for accepting and responding to the identifier resolution request sent by the recursive resolution node.

4. The inter-system data sharing method based on Industrial Internet identifier resolution according to claim 3, characterized in that, Also includes: Construct attribute data templates for the entities; Data from each system within the enterprise is aggregated and organized to identify the entities in each system. The attributes corresponding to each entity are obtained and populated into the attribute data template to obtain the identifier data containing the private identifier for each entity.

5. A system-to-system data sharing system based on Industrial Internet identifier resolution, characterized in that, This includes a generation module, a connection module, and a building module; The generation module is used to: generate an industrial internet identifier for each entity in each system within the enterprise, and establish a positive mapping relationship between the industrial internet identifier of each entity and the private identifier of each entity; The data integration module is used to: integrate data of upstream and downstream enterprises in the industry to which the enterprise belongs, based on industrial internet identifier resolution technology; The construction module is used to: after connecting the data of upstream and downstream enterprises in the industry to which the enterprise belongs, based on the positive mapping relationship, and using the technologies of identifier mapping, heterogeneous identifier recognition and heterogeneous identifier resolution, construct an enterprise service bus based on identifier resolution, which is used to provide data sharing services; The identifier resolution process includes: The identification application sends an identification resolution request to the recursive resolution node to obtain the identification information; The recursive parsing node sends an identifier resolution request to the root node to obtain information about the first-level node to which the identifier belongs; The root node accepts and responds to the identifier resolution request sent by the recursive resolution node, retrieves the corresponding first-level node for the identifier by querying the registration information, and returns the first-level node information to the recursive resolution node; The recursive resolution node sends an identifier resolution request to the first-level node to obtain information about the second-level node to which the identifier belongs; The first-level node accepts and responds to the identifier resolution request sent by the recursive resolution node, retrieves the second-level node with the prefix response by querying the registration information, and returns the second-level node information to the recursive resolution node; The recursive resolution node sends an identifier resolution request to the second-level node to obtain the information of the third-level node to which the identifier belongs; Second-level nodes accept and respond to identifier resolution requests sent by recursive resolution nodes, retrieve the third-level nodes that respond with the prefix by querying registration information, and return the third-level node information to the recursive resolution nodes; The recursive parsing node sends an identifier resolution request to the third-level node to obtain the resolution result; The third-level node is responsible for accepting and responding to the identifier resolution request sent by the recursive resolution node. It retrieves the value set corresponding to the identifier by querying the local database and returns the resolution result to the recursive resolution node. The recursive parsing node returns the parsing result to the identifier application. The parsing result is the value set corresponding to the identifier, or the information of the third-level node to which the identifier belongs. When the resolution result obtained by the identification application from the recursive resolution node is the information of the third-level node to which the identification belongs, the identification application directly sends an identification resolution request to the third-level node to which the identification belongs in order to obtain the identification information. The third-level node to which the identifier belongs is responsible for accepting and responding to identifier resolution requests. It retrieves the value set corresponding to the identifier by querying the local database and returns the resolution result to the identifier application.
