船舶信息网络涉及多个子系统，各子系统之间相互耦合，系统结构复杂，导致控制层与数据层的协同控制性能下降。为此，研究船舶信息网络分层递阶-协同控制优化方法。依据船舶信息网络结构分析结果，将控制器协同优化部署与路由节点优化选取作为控制优化目标，以控制器流量负载与链路带宽等为约束，结合近邻传播分域、协同映射及Dijkstra算法，构成双层递阶-协同控制优化方案，实现网络的控制优化。实验结果表明，该方法数据传输速率为40 Mbit/s的最佳路由路径优化选取。网络数据传输抖动峰值与低谷分别为0.19 ms与0.05 ms，网络传输性能稳定。
The ship information network involves multiple subsystems, which are coupled with each other and have a complex system structure, resulting in a decrease in the collaborative control performance between the control layer and the data layer. To this end, a hierarchical collaborative control optimization method for ship information networks is studied. Based on the analysis of the structure of the ship information network, the controller collaborative optimization deployment and routing node optimization are selected as the control optimization objectives, with controller traffic load and link bandwidth as constraints. Combined with nearest neighbor propagation domain partitioning, collaborative mapping, and Dijkstra's algorithm, a two-layer hierarchical collaborative control optimization scheme is constructed to achieve network control optimization. The experimental results indicate that the optimal routing path optimization selection for a data transmission rate of 40 Mbit/s is achieved using this method. The peak and valley of network data transmission jitter are 0.19 ms and 0.05 ms, respectively, indicating stable network transmission performance.
