Detailed Description
In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of exemplary embodiments of the present application is given with reference to the accompanying drawings, and it is apparent that the described embodiments are only some of the embodiments of the present application and not exhaustive of all the embodiments. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.
Through research and analysis of the prior art, the integration method of the API-based cross-domain model/data needs to rely on the ability of a developer to support the original system or secondarily develop the tool/system, and the cross-domain data source is dynamically updated, so that the change of the tool or the interface easily causes functional failure or causes problems in data exchange. Therefore, the cross-domain model/data integration based on the API needs to be capable of long-term maintenance, and has poor integration effect and high maintenance cost. The mode of the model/data management system (M/DMS) can greatly simplify the integration work of storing and acquiring the model/data by using an integration mode of a middleware machine, but has the problems of redundancy, inconsistency and incompleteness of the model data.
As can be seen from the analysis, the existing cross-domain model/data integration scheme is high in maintenance cost, has data redundancy, and is difficult to ensure the consistency and the integrity of the model/data. In order to solve the problems, the scheme aims to provide a scheme for inquiring data based on a complex product full life cycle digital main line. The scheme is oriented to the full life cycle activities of the complex product, and the model/data management system is utilized to combine the digital main line of the product data map, so that the end-to-end model/data in the full life cycle of the complex product can be obtained according to the query requirement of a user. By applying the query method, the centralized storage of the product model/data can be realized, the consistency and the integrity of the model/data are maintained all the time in the whole life cycle, and the authoritative and credible end-to-end bidirectional model/data service is provided for various data application scenes in the whole life cycle.
As shown in fig. 1, the construction process and functions of the full life cycle digital main line service system of the complex product according to the present solution are as follows:

The integrated software tool or information system can check the model/data into the M/DMS, can update the model/data from the M/DMS reversely, and can acquire the model/data in other software tools or information systems through the M/DMS. The main transfer between the M/DMS and the integrated software tool/system is the structured data/system model, CAX model.
2. Model/data management
(1) Model attribute extraction
For the structured data/system model, its attribute information can be obtained directly. For the semi-structured CAX model, the key attributes of the model are analyzed and extracted through secondary development, such as: for CAD models, the attributes of materials, quality and the like are extracted, and the user-defined attributes are extracted.
(2) Viewing and editing of models/data
The online browsing of the three-dimensional CAD/CAE model is realized, the interactive operations such as rotation, translation, scaling, transparency, hiding, sectioning, measurement and the like can be performed on the model, the three-dimensional annotation is supported to be added/stored on the model, and the attribute information of the model is edited. The method provides a structured system model viewing function, supports the graphical display of various system models, and supports the editing of model properties. Viewing and editing functions for generally structured data are provided.
(3) Version management
The M/DMS can carry out version control on the model/data, and the latest valid principle is adopted by default. Meanwhile, aiming at the development characteristics of multi-state parallelism possibly existing in complex products, the multi-version simultaneous validation and state marking of the model/data are supported. The M/DMS can view the version history of the model/data in an intuitive and graphical manner, that is, actually, a data history is constructed for each model/data, and the source, creator, modifier, creation and modification time, updated content, and the like of the data are recorded. The data histories of the model/data construct dynamic and complete product technical states, and can support summarization, inquiry and tracing of the whole product technical states.
(4) Rights control
The M/DMS supports sharing model data in a cloud link manner, and the cloud link can provide control over access time limit and sharing range. Meanwhile, authority setting can be performed on any group or one model data, and authority control of operations such as checking, editing, checking-in and the like can be performed according to an organization or a person. Support configuration of end-to-end data connections through a connection manager.
(5) Data map construction
Although automatic knowledge extraction and processing techniques are becoming mature, for the field of complex product development, a top-down approach can be used to construct a base data map more efficiently using expert experience. The basic data map is expanded through processing structured, semi-structured and unstructured data of historical product models, so that a complete product data map can be generated. Entities in the data map cover models/data that are all relevant for the full life cycle of the complex product.
(6) Model/data association
Associating the model/data in the M/DMS with the entity in the data map, establishing an explicit association relation between the model/data items, constructing a full life cycle data map of the product, and supporting the intelligent retrieval and pushing of the model/data in a specific model/data application scene. The model/data can be automatically associated with the data map by the same token.
(7) Consistency and integrity verification
The integrity of the data map is checked by checking the condition of the associated model/data through the data map and generating a check report. And (3) checking consistency of the checked model/data, reporting the condition if the inconsistency occurs, and manually checking and confirming the abnormal model data by a person responsible for maintaining the data.
3. Product data map management
Based on the constructed data map, the SPARQL language is utilized to develop reasoning inquiry, and the user is supported to quickly acquire end-to-end model/data in the whole life cycle process.
The scheme can solve the problems of information island and data unidirectional flow in the whole life cycle of the complex product. Compared with the prior art, the method provided by the invention can construct a digital main line supporting full life cycle end-to-end bidirectional data flow, has the advantages of low maintenance cost and no data redundancy, can always maintain the consistency and the integrity of the model/data, and can provide authoritative and credible model and data service for complex product full life cycle activities (such as product technical state management and control, product digital twin, data summarization analysis and the like).
The present solution is further illustrated by way of example below.
As shown in FIG. 1, in the query process, the CAX tool in step 1 is transferred to the M/DMS in an original model or a lightweight format model (such as wrl, jt, obj, stl, etc.), and the system modeling and simulation tool and the information system generate a file in a JSON format and transfer the file to the M/DMS. After receiving the CAX model file, the M/DMS firstly executes model attribute analysis, and then starts to execute step 2 (see FIG. 1) in the query process; after receiving the JSON file, the M/DMS starts to execute step 2. In the query process, step 2 is data parsing and mapping, a script language is used for parsing and storing the JSON file into attribute fields of the model/data, and then the JSON file is associated with nodes in a data map. Step 3 in the query process is data acquisition, and the created data map is queried based on SPARQL by using RDFLib. As shown in fig. 1, step 2.2 in the query process is the viewing and editing of the model/data. And 2D/3D display and interaction operation functions are provided for the CAX model, online visual editing and sharing of the model can be realized, three-dimensional labeling and measurement can be realized, labeling data can be stored, and the sharing of the model and the browsing view angle through links can be supported.
As shown in fig. 2, a schematic diagram of the digital main line supporting end-to-end data flow. Wherein MagicDraw is a system modeling tool and Creo parameter is a three-dimensional CAD tool. Through plug-in development, both can be integrated with the model/data management system. The former submits the system model, and the latter submits the CAX model. After the model/data management system receives the model, model attribute extraction, data analysis and association, consistency verification and confirmation and the like are carried out. After the model is changed in the tool, the model can be submitted to the model data management system again for version updating. When the system model in the MagicDraw needs to acquire data in the CAD model in the Creo Parametric, firstly, a connection manager of a model data management system is utilized to build association between the system model and the CAD model, and then the data of the CAD model can be acquired by utilizing a data acquisition function of an integrated plug-in the MagicDraw. And vice versa.
