基于有向图的运载火箭综合电子系统设计方法
|
摘要
为解决运载火箭综合电子系统各功能模块之间信息交互复杂、传输路径长的问题,提出一种基于有向图的运载火箭综合电子系统设计方法.将运载火箭综合电子系统的功能模块抽象为有向图的节点,利用有向边表示功能模块之间的信息流向,构造运载火箭综合电子系统的功能结构有向图.通过有向图建立运载火箭综合电子系统的邻接矩阵,计算传递次数和可达矩阵,并利用可达矩阵对运载火箭综合电子系统功能结构开展分析与优化.实现运载火箭综合电子系统功能结构的最优层次划分,有效简化信息传输关系,缩短信息传输路径,提升运载火箭综合电子系统信息传输效率37.5%.
Integrated electronic system on launch vehicles suffers from the complex information interaction and transmission process among functional modules. To solve the problems above, a launch vehicle integrated electronic system based on directed graph was proposed in this paper. Functional modules on launch vehicles were regarded as nodes in the directed graph, while information flows were the edges among those modules. Based on the enacted directed graph, an adjacency matrix was then established to represent the complex integrated electronic system. The transfer length and arrival matrix were calculated and analyzed to optimize the whole integrated electronic system. Compared with the traditional design, the proposed system achieves a terser information interaction and transmission process. Moreover, the transmission efficiency of the proposed system can be improved by 37.5%.
