Description
Technical Field
[0001] The invention relates to a method for visualizing and dynamically displaying a functional model based on the SysML language, and belongs to the field of digital design of aerospace products. Background Art
[0002] Model-Based System Engineering (MBSE) is an important direction for the future development of system engineering. Since it was formally proposed in 2007, it has become a hot spot and core of research and application in the system engineering community in recent years (Analysis of Model-Based System Engineering Technology Wu Ying et al. Aviation Science and Technology 2015 No. 09). SysML (Systems Modeling Language, SysML) as the system modeling language of MBSE is widely used in the technical research and application of MBSE.
[0003] In recent years, domestic and foreign research has shown that in the aerospace field, system design based on SysML functional models can achieve complete requirements decomposition and dynamic simulation verification, reducing analysis and design errors. However, due to the large scale and high complexity of the new generation of aerospace products, after the system design is carried out based on SysML functional models, the functional model architecture is relatively complex, usually forming hundreds of different types of diagrams and tens of thousands of model elements. When checking and reviewing the system design results based on the functional model, for non-digital professional system designers, not only do they need to spend a lot of time in advance to learn the MBSE concept and SysML language, but they also need to understand, find and confirm the design results of system functions, interfaces, information flows, etc. in the huge and complex functional models, which affects the efficiency of model design and review, and may affect the development progress of aerospace products.
[0004] In order to solve this problem, it is necessary to develop a method for visualizing and dynamically displaying functional models based on the SysML language. The functional models can be visualized and dynamically displayed through a graphical user interface (GUI). Designers who are not familiar with the SysML language and MBSE concept can intuitively analyze the flight actions performed by various systems of aerospace products at various time points in the timing design, understand and confirm the system design results, and check the correctness of the system design solution based on the functional model, thereby improving the efficiency of functional model design and review.
