Description

Technical Field

[0001] This invention relates to the field of data management, specifically to a metadata registration and application system and method for the entire civil aircraft manufacturing process. Background Technology

[0002] Currently, data from the entire civil aircraft manufacturing process is scattered across different systems and departments, making effective collaboration difficult. In other industry scenarios, a series of unified metadata configurations have begun to be implemented. For example, in the water industry, publication number "CN117708086A" describes "Metadata Model Construction Method and Metadata Management Platform for the Water Industry." In the aviation field, there are some metadata recording methods that focus on a specific stage. For example, publication number "CN119358525A" describes "An Information Recording Method, System and Medium for the Civil Aircraft Assembly and Manufacturing Process." However, these methods are limited to information recording and storage during the civil aircraft assembly process, and there is currently little mention of metadata registration and application for the entire civil aircraft manufacturing process.

[0003] Currently, the civil aviation manufacturing industry faces numerous challenges in data management. Existing data modeling methods are ill-suited to the complex business processes and diverse data types of the civil aviation manufacturing industry. The data in the civil aviation manufacturing industry covers multiple stages such as design, production, assembly, quality inspection, and maintenance. The data is scattered and stored in different systems and departments, making it difficult to communicate with each other. The lack of unified data standards greatly limits the analysis and sharing of data, failing to meet the needs of enterprises for comprehensive utilization and in-depth data mining, and thus hindering the digital transformation and development of the civil aviation manufacturing industry. Summary of the Invention

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0034] Please see Figure 1 - Figure 3 As shown, the present invention is a metadata registration and application system and method for the entire civil aircraft manufacturing process.

[0035] Firstly, please refer to Figure 1 As shown, this invention provides an implementation scheme, a metadata registration and application system for the entire civil aircraft manufacturing process, comprising:

[0036] Metadata storage module 1: Used to store the constructed metadata model and the collected metadata;

[0037] Metadata synchronization module 2: Enables data synchronization with external data sources, ensuring the real-time nature and consistency of metadata;

[0038] Metadata Management Module 3: Provides metadata management functions, making it convenient for administrators to maintain and manage metadata. It also controls metadata versions and records the metadata change history.

[0039] Metadata storage module 1 employs a high-efficiency database management system to ensure data storage security and fast access.

[0040] The metadata management module 3 provides management functions such as creating, editing, and deleting metadata, making it convenient for administrators to maintain and manage metadata. At the same time, it supports version control of metadata and records the change history of metadata.

[0041] Specifically, the bidirectional signal at the output of metadata storage module 1 is connected to the input of metadata synchronization module 2.

[0042] Specifically, the bidirectional signal at the output of the metadata synchronization module 2 is connected to the input of the metadata management module 3.

[0043] Specifically, the bidirectional signal at the output of the metadata management module 3 is connected to the input of the metadata storage module 1.

[0044] In use, administrators define the structure of the metadata model, set basic attributes, constraints, and classifications of the metadata through the management interface of the metadata management module 3. The metadata management module 3 stores the newly created metadata model in the database of the metadata storage module 1 via a bidirectional signal connection. The metadata storage module 1 uses an efficient database management system to securely persist the model and generate an initial version. The metadata synchronization module 2 pulls the latest metadata information from external data sources according to a preset scheduling strategy. The metadata synchronization module 2 writes the collected metadata changes to the metadata storage module 1 via a bidirectional signal connection. The metadata storage module 1 receives and updates the corresponding metadata records, recording the state before the change. Simultaneously, the metadata synchronization module 2 also synchronizes existing metadata models or rules in the metadata storage module 1 to the external data source, achieving bidirectional synchronization and ensuring consistency. Administrators can query or browse metadata in the system through the metadata management module 3. The metadata management module 3 reads the latest metadata information from the metadata storage module 1 in real time for display via a bidirectional connection. When administrators need to modify a piece of metadata, they perform an editing operation on the metadata management module 3 interface. The metadata management module 3 will first... The metadata management module 3 sends a request to the metadata storage module 1 to obtain the latest version and content of the metadata. When an administrator submits modifications, the metadata management module 3 sends the modified content to the metadata storage module 1 via a bidirectional connection for updating and saving. If metadata needs to be deleted, the metadata management module 3 sends a deletion request to the metadata storage module 1. The metadata storage module 1 usually does not physically delete it, but marks it as "deleted" and saves its final state as a historical version for auditing and recovery. When metadata is changed through the metadata management module 3 or the metadata synchronization module 2, a closed-loop update process is triggered to ensure consistency of status across all stakeholders. In the metadata management module 3, the administrator selects the metadata entity to be viewed and, through viewing historical versions or similar functions, requests all version records of that entity from the metadata storage module 1. The metadata storage module 1 returns a complete list of version change history. The administrator can compare the differences between different versions and, if necessary, roll back the metadata to a specified historical version. The rollback operation is initiated through the metadata management module 3, creating a new version change record in the metadata storage module 1, thus forming a complete and auditable change chain.

[0045] Secondly, please refer to Figure 2-3 As shown, according to the implementation scheme of the first aspect above, the present invention also provides an implementation scheme, a metadata registration and application method for the entire civil aircraft manufacturing process, comprising the following steps:

[0046] Step 1: Business Scenarios and Requirements Acquisition: Conduct a comprehensive analysis of the entire business process of the civil aviation manufacturing industry, and at the same time, clarify the data analysis and sharing scenarios;

[0047] Step 2: Core Metadata Collection: Based on business processes, data analysis, and sharing scenarios, collect core metadata entities and elements to obtain metadata;

[0048] Step 3: Database table structure mapping: Map the metadata object to the database table structure to complete the metadata registration;

[0049] Step 4: Metadata Update: Adjust and optimize the metadata model in a timely manner.

[0050] Specifically, in step one, the entire business process includes the design business area, the manufacturing business area, the testing business area, the customer management business area, the supplier management business area, and the support and assurance business area.

[0051] Specifically, in step one, the data analysis and sharing scenarios are defined as including the optimization analysis of design schemes, the efficiency evaluation of the production process, product quality traceability, and cross-departmental data sharing.

[0052] Specifically, in step two, the data collection methods include internal business forms and a unified data operation platform.

[0053] Specifically, step three requires ensuring that the fields and data types of the metadata are consistent with the database table structure.

[0054] Specifically, in step four, metadata updates include periodic re-collection and updating of core metadata, and updates based on business changes and data needs.

[0055] A method for metadata registration and application across the entire civil aircraft manufacturing process: Taking the process instructions for XXX parts in the civil aviation manufacturing industry as an example, this paper details the implementation process of the metadata model construction method.

[0056] Step 1: Business Scenarios and Requirements Acquisition: Conduct a comprehensive analysis of the entire business process of the civil aviation manufacturing industry. At the same time, clarify the data analysis and sharing scenarios. The entire business process includes design, manufacturing, testing, customer management, supplier management, and support and assurance. The data analysis and sharing scenarios include design optimization analysis, production process efficiency evaluation, product quality traceability, and cross-departmental data sharing.

[0057] A comprehensive analysis of the entire business process in the civil aviation manufacturing industry is conducted, including business areas such as design, manufacturing, testing, customer management, supplier management, and support and maintenance. Simultaneously, data analysis and sharing scenarios are clearly defined, such as design optimization analysis, production process efficiency evaluation, product quality traceability, and cross-departmental data sharing.

[0058] The process instructions for part XXX are managed by the supplier in the civil aircraft industry, and the business process includes parts processing, assembly, and performance testing. Data analysis requirements include parts processing accuracy analysis, assembly efficiency evaluation, and performance test result analysis; data sharing requirements involve data exchange between the production department, design department, and quality inspection department.

[0059] Step 2: Core Metadata Collection: Based on business processes, data analysis, and sharing scenarios, collect core metadata entities and elements to obtain metadata. Collection methods include internal business forms and the unified data operation platform.

[0060] Based on the identified business processes, data analysis, and sharing scenarios, core metadata entities and elements are collected. Collection is achieved through internal company business forms, each covering several business attributes. Through a unified data operations platform, business forms are registered as business objects, business form attributes are registered as data objects, and subsequently, these data objects are registered as metadata.

[0061] The business form for the process instruction of part XXX is obtained from the company's internal website. The business form contains business form attributes such as part model, processing parameters, and processing equipment. Through the company's unified data management platform, the business form is registered as a business object, and its business form attributes are registered as data objects. The obtained data objects can become metadata after registration.

[0062] Step 3: Database table structure mapping: Map the metadata object to the database table structure to complete the metadata registration. It is necessary to ensure that the fields and data types of the metadata are consistent with the database table structure.

[0063] The registered data objects are mapped to the database table structure, completing the metadata registration. In this step, it is essential to ensure that the fields and data types of the metadata are consistent with the database table structure. Following the prescribed data extraction, transformation, and processing procedures, the collected data is stored in the corresponding database tables, achieving structured data storage.

[0064] The established metadata model is mapped to the database table structure, and corresponding database tables are created, such as the part name, raw material size, process content, and order number for part XXX. Appropriate fields and data types are set, and the collected data is stored in the database tables according to the prescribed process. After completing the metadata registration, the mapping relationship between a specific attribute of the process instruction for part XXX and the database table is completed. This data can then be published as a data asset for use by various departments within the company.

[0065] Step 4: Metadata Update: Adjust and optimize the metadata model in a timely manner. Metadata updates include regular re-collection and updating of core metadata, and updates based on business changes and data needs.

[0066] Regularly re-collect and update core metadata, and adjust and optimize the metadata model in a timely manner according to business changes and data needs to ensure the accuracy and applicability of the metadata model.

[0067] With the improvement of the production process of XXX parts, the introduction of new equipment, and changes in business needs, the core metadata is regularly re-collected and updated, and the metadata model is adjusted to ensure that it meets actual business needs.

[0068] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
