Design of Star Network Architecture of Weapon System Based on FlexRay Bus

针对武器系统中总线型FlexRay网络拓扑阻抗匹配设计难、端节点动态变化的特点,开展了基于有源星型网络拓扑的弹地间FlexRay网络架构设计,并对网络中各节点间信号质量进行了仿真对比分析。对有源星型设备内部硬件结构及信息调度时序进行了优化设计,模拟武器系统端节点并入、分离等工况,对信号稳定性进行了半实物仿真验证,结果表明:基于该星型网络架构的FlexRay总线网络可为武器系统提供灵活可靠的数据传输,具有很好的应用价值。

In view of the characteristics of bus FlexRay network topology impedance matching and dynamic changes of terminal nodes in weapon system,an intermissile FlexRay network architecture design based on active star network topology was carried out,and the signal quality between nodes in the network was simulated and analyzed.Based on the optimization design of the internal hardware structure and information scheduling timing of the active star device,the terminal node integration and separation of the weapon system are simulated,and the signal stability is verified by the semi-physical simulation.The results show that the FlexRay bus network based on the star network architecture can provide flexible and reliable data transmission for the weapon system,and had good application value.
