Description

Technical Field

[0001] The invention relates to a method for constructing a function model library and a template library based on SysML language, and belongs to the field of digital design of aerospace products. Background Art

[0002] SysML (Systems Modeling Language, SysML) is a system modeling language widely used in model-based system engineering (Model-Based System Engineering, MBSE) technology. In recent years, practice has proved that the functional model built based on the SysML language can describe the degree of compliance between product functions and design requirements in the product design process, including functional requirements, performance requirements, integration interface requirements, universal requirements, test verification requirements, etc., which can effectively enhance the ability of overall and subsystem collaborative design, and ensure the consistency and uniqueness of system design information and data transmission, so as to realize the rapid design and iterative optimization of aerospace product system solutions based on model support.

[0003] The new generation of aerospace model products have the characteristics of large system scale, high complexity, many collaborative participating units, and cross-disciplinary applications. When aerospace designers carry out functional modeling work based on the SysML language, they often encounter low functional modeling efficiency, large manual repetitive workload, inconsistent design processes, non-standard modeling methods, and inconsistent expressions due to the complicated functional modeling process and steps, different functional modeling levels of designers, and different modeling habits. These problems may further cause problems such as the inability to deliver and integrate downstream models on time, which will seriously restrict the improvement of the quality and efficiency of functional model design.

[0004] Therefore, it is necessary to study a method for building a functional model library and template library based on the SysML language, facing the system design of aerospace model products, based on relevant standards and specifications of functional models, combined with the habits of aerospace designers, to form aerospace product system functional modeling templates, general model libraries and professional model libraries, and use templates and model libraries to quickly complete modeling and selection, thereby standardizing the process of aerospace product systems using MBSE technology to carry out system functional modeling, and improving modeling efficiency and design quality. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a method for constructing a functional model library and a template library based on the SysML language to solve the problems of non-standard and heavy workload of functional modeling based on the SysML language in the prior art, realize the standardized model-based functional modeling process, demonstrate its application in the digital design of aerospace model products, improve modeling efficiency and quality, and lay the foundation for improving the forward design capability of aerospace model product systems and effectively supporting the digital construction of equipment.

[0006] The technical solution of the present invention is: a method for constructing a function model library and a template library based on the SysML language, comprising:

[0007] Build a functional modeling template library based on the aerospace product functional modeling process;

[0008] Build a general model library of functional models based on the customized function of aerospace product functional modeling;

[0009] Based on the functional model examples of aerospace products, a professional model library of functional models is constructed.

[0010] The functional modeling template library is constructed based on the aerospace product functional modeling process, including:

[0011] Construct the black box part of the overall scheme design of the functional modeling template, the white box part of the overall scheme design of the functional modeling template, the subsystem design part of the functional modeling template, and the overall comprehensive integration verification part of the functional modeling template;

[0012] The elements that influence each other in the overall design black box, overall design white box, subsystem design, and overall comprehensive integration verification of the functional modeling template are associated through the "inheritance" relationship of the SysML language and the element synchronization function to form a functional modeling template library, so that when an element is changed, its associated elements are updated synchronously;

[0013] Functional modeling templates of different types of aerospace products are uniformly managed and stored in the functional modeling template library, and the functional modeling template library is published and shared with designers responsible for corresponding aerospace products. Before functional modeling, designers start functional modeling by selecting functional modeling templates from the functional modeling template library and based on various example diagrams and example elements.

[0014] The overall scheme design black box part of the functional modeling template includes a stakeholder requirement table template, a space product operation scenario use case diagram template, a space product and external environment interaction signal template, and an overall indicator template.

[0015] The overall design white box part of the functional modeling template includes an aerospace product system function analysis activity diagram template, an aerospace product system composition diagram template, an aerospace product system interface internal block diagram template, an aerospace product system signal template, a system function and stakeholder requirement traceability matrix template, an overall to subsystem requirement table template, an overall to subsystem requirement and stakeholder requirement traceability matrix template, a system function and overall to subsystem requirement traceability matrix template, a system simulation configuration template, and a system indicator template.

[0017] The overall comprehensive integration verification part of the functional modeling template includes subsystem and important single-machine supporting component diagram template, subsystem and important single-machine interface comprehensive internal block diagram template, and indicator comprehensive confirmation template.

[0018] The functional model universal model library includes: a custom development library, a term library and a unit library;

[0019] The custom development library uniformly manages and stores the custom development functions of the functional modeling tool, publishes and shares the custom development library with designers, and enables designers to select the required custom development functions from the custom development library and use them in the functional model when carrying out functional modeling, including automatic inspection functions, document generation functions and UI interface development functions;

[0020] The terminology library uniformly manages and stores the terminology lists of various aerospace products. The terminology lists store the definitions or explanations of professional terms used in the development of aerospace products. The terminology library is published and shared with designers, so that when designers use professional terms in modeling, the corresponding definitions or explanations of the terms can be displayed in the functional model in real time.

[0021] The unit library centrally manages and stores the definitions of commonly used units in the development of aerospace products, publishes and shares the unit library with designers, and enables designers to use commonly used units that are in line with the habits of aerospace product designers or unique to aerospace products when establishing indicators during modeling.

[0022] The functional model professional model library is constructed based on the aerospace product functional model example, including:

[0023] Construct an overall professional function model library to uniformly manage and store the overall hierarchical elements of aerospace product function model instances according to aerospace product application scenarios; the overall hierarchical elements include overall subsystem design requirements instances, inter-system interface types and interface instances, inter-system signal instruction instances, subsystem execution action logic instances, and subsystem indicator instances;

[0025] The overall professional function model library will be published and shared with aerospace product overall designers, and the subsystem professional function model library will be published and shared with aerospace product subsystem designers. When designers carry out new function model modeling, they can select corresponding professional function model instance elements for reuse, thereby achieving rapid modeling.

[0026] The advantages of the present invention compared with the prior art are:

[0027] (1) The complex functional modeling process in the MBSE methodology is solidified into a functional modeling template, and the designer's modeling work is guided by the rapid reuse of relevant requirements, interfaces, signals, and functional logic SysML elements in the professional functional model library, thereby greatly shortening the designer's functional modeling work time, reducing the learning cost and difficulty, not only reducing the repetitive operations of model design, but also realizing the rapid establishment of the model, improving the efficiency of functional model modeling and design.

[0028] (2) Carrying out functional modeling based on the functional model library and template library can ensure the standardization of aerospace product system functional modeling to a large extent, quickly and accurately design functional models that meet standards and specifications, reduce the probability of design errors, and significantly improve the quality of system solution design based on functional models.
