Description
Technical Field
[0001] The present invention relates to a digital prototype development system integrating multiple fields and a method for constructing a digital prototype thereof, belonging to the technical field of digital prototypes. Background Art
[0002] In the design, production, testing and delivery of electronic single-unit products, a set of mature and efficient research and development process systems has been formed. With the changes in the characteristics of scientific research and production tasks and the urgency brought about by digital transformation, there are some deficiencies and inadequacies in the collaborative design and verification during the research and development process of electronic single-unit products. It is mainly reflected in the following aspects: The development of electronic products is highly dependent on hardware, with a long iteration cycle, lacking a rapid verification and iteration research and development process based on MBSE; in terms of the performance evaluation of electronic products, as well as in the performance and timing simulation verification of on-board operating systems and application software, there is a lack of a digital prototype of a control system electronic product based on models; in the traditional research and development mode of on-board operating systems and driver software, the transmission of requirements and designs based on documents is prone to ambiguity problems, and the verification is lagging, resulting in an increase in system research and development costs.
[0003] Currently, digital prototype construction technology is mainly applied to construct a 3D digital prototype of CAD, and it is difficult to comprehensively integrate professional models of different disciplines such as software models, circuit models, and physical field-related models into a complete digital prototype model. Moreover, the models in the digital prototype are tightly coupled with the operating platform. When the operating platform is replaced, the models also need to be modified accordingly. In the aspect of model-based software development, although it has been piloted in multiple different types of projects, it is found during the pilot process that there is a lack of tight connection between this research and development mode and the existing research and development systems (management system, technical system), making it difficult to widely promote and apply the research and development process based on model-based systems engineering in different types of projects. Summary of the Invention

[0013] Further, during the re-modeling process, the data elements required for modeling are preferentially selected. If there are no required data elements, the data elements are created by itself; the processing module stores the obtained modules, parameters, and algorithms in a unified format in the corresponding database in the storage module.
[0014] Further, when a digital prototype needs to be constructed, according to the specific modeling type, the single-machine sub-module or the system sub-module under the modeling module is called;

[0040] A modeling module for using the models, parameters, and algorithms in a unified format to construct a single - machine digital prototype model and a system digital prototype model and sending them to the storage module.
[0041] In the second aspect, based on the same inventive concept, the present invention also provides a digital prototype construction method implemented using the above - mentioned multi - domain integrated digital prototype development system, including:
[0042] Acquiring models, parameters, and algorithms in other fields input externally; the models include pre - installed software models, circuit models, mechanical models, physical field models, single - machine models, and system models;

[0044] Using the models, parameters, and algorithms in a unified format to construct a single - machine digital prototype model and a system digital prototype model and storing them.
[0045] In the solution provided by the embodiments of the present invention, the multi - domain integrated digital prototype development platform is as Figure 1As shown in the figure, it mainly includes: a collection module, a processing module, a modeling module, and a storage module.
[0046] The collection module is used to receive models, parameters, and algorithms from other fields.
[0047] The processing module is used to virtualize the models, parameters, and algorithms from other fields collected by the data collection module into models, parameters, and algorithms in a unified format based on the FACE architecture, and send them to the storage module.

[0049] The modeling module specifically includes: a single-machine sub-module and a system sub-module.
[0050] The single-machine sub-module is used to call the required models, parameters, and algorithms from the storage module, combine them to obtain various single-machine digital prototype models, and send them to the storage module.
[0051] The system sub-module is used to call the required single-machine models from the storage module, combine them to obtain various system digital prototype models, and send them to the storage module.

The storage module includes: a software model library, a circuit model library, a mechanical model library, a physical field model library, a single-machine model library, a system model library, a parameter and algorithm library, etc.
[0053] The method for the multi-domain fusion digital prototype development platform to build a digital prototype is as follows:
[0054] The staff prepares models, parameters, and algorithms in other fields in advance and sends them to the digital prototype development platform through the acquisition module. The acquisition module sends the received models, parameters, and algorithms to the processing module. The processing module is pre-configured with a semantic analysis model and a unified description model based on the FACE architecture. After receiving the models, parameters, and algorithms sent by the acquisition module, the processing module imports the parameters and algorithms in other fields into the semantic analysis model, and then inputs the analysis results into the unified description model to obtain parameters and algorithms that conform to the platform specifications. The processing module then imports the models in other fields with different scales and dimensions into the semantic analysis model to disassemble the models, obtains fields that conform to the platform rules, and then inputs the analysis results into the unified description model to re-model according to the platform modeling rules, gradually refining from the conceptual data model, logical data model, and platform data model.

Define the semantic meaning, logical relationship, and precision of the data elements used in the model development process, and bind the mapping from the elements in the model to the programming language data structure, so as to unify the scales and dimensions of each model and obtain models in other fields that conform to the platform specifications. During the re-modeling process, the data elements required for modeling are preferentially selected. If there are no required data elements, the service layer can create the data elements by itself. The processing module stores the obtained modules, parameters, and algorithms in a unified format in the corresponding database in the storage module for storage.
[0055] When a digital prototype needs to be built, according to the specific modeling type, the single-machine sub-module or the system sub-module under the modeling module can be called. When building a single-machine digital prototype model, the single-machine sub-module calls the required models, parameters, and algorithms from the corresponding database in the storage module and combines them according to the platform preset rules to obtain a single-machine digital prototype model. The obtained single-machine digital prototype model is sent to the single-machine model library in the storage module for storage. When building a system model digital prototype, the system sub-module calls the required models, parameters, algorithms, and single-machine digital prototype models from the corresponding database in the storage module, and then combines them according to the platform preset rules to obtain a system digital prototype model.
