The Design Technology for the Spacecraft Electrical System Based on the MBSE Method

The application of MBSE technology in spacecraft electrical system design is studied. A complete electrical system implementation scheme is established from requirement analysis, function definition,logic design, logic implementation an physical implementation. The mapping and correlation methods between different levels are analyzed. According to the characteristic of the spacecraft electrical system, a new systematic engineering solution is proposed. Taking SystemWeaver as the development platform, taking typical spacecraft management platform as the research object, we carry out forward design form top to bottom, carry out demand analysis based on top-level input, and define functions based on functional requirements. On the basis of meeting relevant technical standards and experience, we use logic design and logic implementation to meet various functional definitions, and finally, we implement the system through the physical layer. The whole process of forward design of spacecraft electrical system based on MBSE is formed.
