高铁调度系统信息传递及拓扑结构分析

Information transition and topology analysis on Chinese high-speed railway dispatching system

根据图论将高速铁路调度系统抽象为一个有权无向网络,利用信息熵理论将系统中传递的信息量化为连接节点的边的权重,并利用复杂网络定义网络中各节点的信息度和延伸度,建立关联矩阵及边的功能矩阵来描述节点和边在网络中相互作用关系,分别建立节点重要度、边的重要度和节点关联度的计算模型,并设计分析问题的求解过程及算法复杂度。以高铁区域调度台为例,得出分析系统以列调为中心,CTC主机、供电调度、维修调度、计划调度、客服调度以及动车调度为次核心圈的三环辐射的混合网络布局,为保障系统的稳定性,预防干扰明确保护对象。

On the basis of graph network theory,a weighted undirected network was established to illustrate thedispatching system of Chinese high-speed railway.Combined with information entropy theory,the weight of eacharc was calculated according to the characteristics and amount of on-boarding information.Furthermore,theimportance of nodes,stretch of nodes,correlation matrix and path performance matrix were defined to show theinteraction relationship between nodes and arcs by the means of complex network theory.The problem-solvingmethod was designed and complexity of the algorithm was analyzed.Finally,the experimental test was carried onthe dispatching network of high-speed railway.The conclusion is that train dispatching post is the core of thesystem,and the second-central cycle around train dispatching post consists of CTC host,power scheduling post,maintenance scheduling post,plan scheduling post,the scheduling post of the service and vehicle scheduling post.In this way,the priority orders of protection objectives are obtained to enhance the safety and reliability of thesystem.
