基于工控网络拓扑结构的可视化分层方法

摘要

为了实现工控网络组态的拓扑结构到二维平面的无交叉映射显示,从自主可控PLC的网络拓扑出发,提出按照广度优先生成树的高度对拓扑结构进行分层,根据层次的划分,每个界面只显示该层组态界面信息,简化了组态画面的复杂性,强化了组态拓扑的逻辑划分.通过统计每个节点可连通的叶节点数量分析节点的关键度,利用关键度分析网络组态中的节点,并提示预警.%In order to realize the non-cross-map display of the topology industrial control network topology to the two-dimensional plane,this paper proposes a hierarchical visualization method,which based on the height of the tree of the autonomously controlled PLC.According to the hierarchical division,the interface only displays the layer configuration interface information.This method simplifies the complexity of the configuration screen,and strengthens the logical partitioning of the configuration topology.By analyzing the key degree of the node that can be connected by each node,the nodes in the network configuration are analyzed by the key degree and the warning is indicated.
