基于MBSE的卫星通信系统建模与仿真

Modeling and Simulation of Satellite Communication System Base on MBSE

针对复杂卫星通信系统建设与应用中面临的设计、描述、验证、确认等问题,提出基于MBSE开展卫星通信系统立项论证、顶层设计和工程建设的设计方法。参考美国国防部体系结构框架(DoDAF),使用系统架构设计工具(SA)构建卫星通信系统的功能模型、节点模型和流程模型等系统视图(SV),开展基于模型驱动的数字化仿真,通过分析仿真数据验证系统设计的正确性、合理性和可行性。结果表明采用该方法在系统设计阶段能够有效识别风险,验证和确认设计方案,为卫星通信系统立项论证、顶层设计和工程建设提供有力支撑。

A method based on model-based systems engineering(MBSE)for the demonstration,top-level design and engineering construction of the satellite communication system was introduced,which was aim at the problem of design,description,verification and validation in the construction and application of complex satellite communication system.According to the system design standard base on department of defense architecture framework(DoDAF),the system views(SV)such as function model,node model and process model were built by using the system architecture(SA)design software.Through the digital simulation based on model driven and the analysis of simulation data,the correctness,rationality and feasibility of the system design were verified.The results showed that this method can effectively identify risks in the system design stage,verify and confirm the design scheme,and provide strong support for project demonstration,top-level design and engineering construction of satellite communication system.
