高速铁路行车指挥系统信息检测仿真研究

High-Speed Railway Traffic Command System Information Detection Simulation Research

对高速铁路行车指挥系统信息进行准确检测,可以保证高速铁路的行车安全。进行行车指挥系统信息检测时,应对指挥信息网络统计特征的特征量进行提取,并分析高速铁路行车指挥网络整体运行规律,利用运行规律进行信息检测,而传统方法利用局部模块度值最大的节点集合作为训练样本,对指挥系统进行信息检测,但不能准确提取统计特征的特征量,不能对行车规律进行分析,存在理论性差、信息检测误差大等问题。提出一种改进复杂网络理论的高速铁路行车指挥信息检测方法。上述方法先获取列车运行状态和当前位置、运行速度和列车运行调度控制之间的关系,求取其关系映射函数,根据复杂网络理论将各级指挥机构和通信设备抽象成节点,描述指挥信息网络统计特征的特征量,计算出高速铁路行车指挥信息网络整体的演化规律,以计算的结果为依据完成对高速铁路行车指挥信息检测。仿真结果表明,改进方法可以有效地保障高速铁路行车安全正点运行。

An information detection method of traffic command system in high-speed railway is proposed based on modified complex network theory. Firstly, the train operation state and the relationship of current position, run speed and dispatcher control of train operation are obtained to resolve its relational mapping function. Then the commanding institution with all levels and communication device is abstracted into node according to complex network theory, and the characteristic quantity of statistical feature in command information network is described. The overall evolution law in information network of traffic command is worked out. Finally, the information detection of traffic command in high -speed railway is completed according to the calculating result. The simulation results show that the modified method can ensure safe and punctual running of high-speed railway traffic effectively.
