摘　　要：为了提升铁路应急通信质量,解决单层铁路应急通信网络的弊端,提出基于双层优化的铁路应急通信网络拓扑设计。设计传输骨干网约束条件,根据约束条件判断节点间距离能否建立通信链路;构建双层优化的铁路应急通信网络模型,利用模型优化铁路应急通信网络拓扑结构,将优化后的链路权重输入至生成对抗神经网络中完成网络拓扑结构的优化,实现基于双层优化的铁路应急通信网络拓扑设计。实验结果表明,所提方法的铁路应急通信网络拓扑设计稳定性高、时效性强、抗毁性强。In order to improve the quality of railway emergency communication and solve the disadvantages of single-layer railway emergency communication network, a railway emergency communication network topology design based on double-layer optimization is proposed. Design the constraints of the transmission backbone network, and judge whether the distance between nodes can establish a communication link according to the constraints;Build a two-level optimized railway emergency communication network model, use the model to optimize the railway emergency communication network topology, input the optimized link weight into the generated confrontation neural network to optimize the network topology, and realize the railway emergency communication network topology design based on the two-level optimization. The experimental results show that the proposed railway emergency communication network topology design has high stability, strong timeliness and strong survivability.
