Description

Technical Field

[0001] The invention relates to the technical field of system engineering and complex system design, and in particular to a model conversion method supporting the design of a power supply and distribution system for a launch vehicle. Background Art

[0002] With the increasing complexity of systems, Model-Based System Engineering (MBSE) is increasingly being applied to the architectural design process of complex systems, and is increasingly becoming a complex system architecture model. MBSE is a formal application of modeling starting from the conceptual design stage to support system requirements, design, analysis, verification and validation activities, and continues throughout the development and subsequent life cycle stages. With the continuous expansion of system scale, system design pays more and more attention to rapid development. The MBSE method takes the formalized system architecture model as the core, and realizes the (semi-) automatic generation of the model through the model-driven development method to ensure the traceability of model information and improve development efficiency. Model transformation is a key method of model-driven development, also known as model-to-model transformation. It obtains element information in the source model through model query, and transforms and generates the target model according to the mapping rules from the source model elements to the target model elements. Through the model transformation method, a high-abstract level architecture model can be generated into a low-abstract level architecture model. System architects do not need to consider the platform-related implementation details too early, and focus on the overall business logic of the system to improve the design efficiency and design quality.

[0003] However, the power supply and distribution system of the high-dynamic and high-cooperative launch vehicle based on MBSE has the following problems:

[0004] (1) The development efficiency of the architecture model of the launch vehicle power supply and distribution system is low: The power supply and distribution system follows the four-stage design process of requirements-function-logic-physical. There is a process of design element transfer between different design stages or different steps in the same design stage. This process is done manually. Engineers need to manually build all models of the launch vehicle power supply and distribution system, even if there is a process of design element transfer between these models. This is inefficient and time-consuming.

[0005] (2) It is difficult to ensure the consistency and traceability of the design process: During the design of the power supply and distribution system of the launch vehicle, there is a transfer of design elements between different design steps. The current design process relies on a large number of manual operations and data transfer, which is prone to human errors. The manually transferred design information and data may be omitted or misunderstood during multiple conversions, resulting in inconsistent design information at different design stages, which increases the design risk.

[0006] Therefore, the present invention proposes a model conversion method that supports the design of a power supply and distribution system for a launch vehicle to overcome the above-mentioned problems and defects. Summary of the invention

[0007] The purpose of the present invention is to provide a model conversion method that supports the design of a launch vehicle power supply and distribution system, supports the automatic (semi-automatic) construction of design models for some stages in the power supply and distribution system architecture design process, and improves the design efficiency of engineers and the consistency and traceability of design information transmission.
