摘要
研究了一种基于SysML建模语言的双余度飞控系统软件的设计方法。分析了双余度飞控计算机的硬件结构,利用SCADE建模工具建立软件的系统架构模型,通过SysML的内部块图构建双余度管理模型。以某双余度飞控系统为例,利用SCADE提供的仿真工具对双余度管理模型进行仿真验证,结果表明所提出的设计方法可行有效。
A design of dual-redundancy flight control system software based on SysML is researched. Firstly, hardware structure of dual-redundancy flight control computer is introduced, system architecture model of software is built by SCADE modeling tool. Secondly, build dual-redundancy management model by internal block diagram of SysML.At last, take one kind of Dual-redundancy flight control system for example,dual-redundancy management model is verified and validated by simulation tool of SCADE, which results show that this design is feasible and effective.
