基于SysML的通信卫星转发器系统设计

The Design of Communication Satellite Transponder System Based on SysML

传统通信卫星转发器系统的设计方法通过功能、原理和结构三种视图之间的映射实现产品从需求到实现的转换,针对基于文档的设计中存在难于维护三种视图一致性以及需求指标追溯困难等问题,本文研究了基于模型的转发器系统设计方法及工程应用。基于MagicGrid方法论,自顶向下地建立了转发器系统的需求模型、行为模型、结构模型和参数模型,并通过仿真完成了转发器系统配置方案的验证。该方法保证了转发器系统设计过程中数据的一致性、需求的可追溯性,提高了设计效率,可有效应用于复杂通信卫星系统的设计。

The traditional communication satellite transponder system is realized by the transformation from requirement to realization through mapping among three views of function,principle and structure.Because of the difficulties to maintain the consistency of three views and traceability of requirement indicators based on document,the model-based method and engineering application is studied.In this paper,the requirement models,behavior models,structure models and parametric models of transponder are established from top to bottom using MagicGrid,and the system configuration is verified by simulation.This method guarantees the consistency of data and the traceability of requirements in the design process of the transponder system,and improves the design efficiency.It can be effectively used in the design of complex communication satellite system.
