基于模型系统工程方法的卫星测控模拟器设计

MODEL-BASED SYSTEM ENGINEERING METHOD FOR DESIGN OF SATELLITE TELECOMMAND&TELEMETRY SIMULATOR

在卫星测控模拟器设计领域,为了解决传统设计方式信息孤立、内容表述不统一、设计追踪困难、产品设计重用效率较差和难以直接仿真验证的问题,提出基于模型的系统工程(Model-Based Systems Engineering,MBSE)的卫星测控模拟器设计,产品设计内容以模型形式表达。在需求模型设计方面,利用系统建模语言(System Modeling Language,SysML)的需求图、用例图、状态机图和参数图进行产品需求论证;在技术方案模型设计方面,利用SysML的块定义图、内部模块定义图和活动图进行产品设计。针对MBSE设计的仿真验证,提出利用脚本语言结合中间件,进行SysML模型和外部模型进行协同验证的方法,实现了模型设计与快速验证的并行开展。

In the field of satellite telecommand&telemetry simulator design,to solve the problem of isolated traditional design information,inconsistent content expression,difficulty of design tracking,poor efficiency of reuse capability and difficulty of direct verification,a model-based system engineering method for satellite telecommand&telemetry simulator design is proposed,and the product design output style is model.In terms of the requirement model design,requirement diagram,use case diagram,state machine diagram and parameter diagram of SysML were adopted to demonstrate product requirements.In terms of the solution model design,block definition diagram,internal block diagram and activity diagram of SysML were adopted for product design.For the simulation verification of MBSE,a collaborative verification method of SysML model and external model by using script language and middleware was proposed,which realized the parallel development of model design and rapid verification.
