摘要
维护终端是高速铁路信号系统的一个组成部分,是进行系统状态监测和维护的一个重要手段,也是系统智能运维技术的载体,计算机联锁系统为典型的地面信号系统。在对计算机联锁系统网络监测需求研究的基础上,采用图论模型方法,对其主机和内部网络、外部网络通道状态进行模型显示;基于特定的计算方法解决了通道显示问题;并基于图论模型和模糊推理的混合推理方法,对典型的交换机故障、通道故障进行推理分析。经过研究证明,针对图论和推理进行适应性的改进,能够解决复杂的高速铁路信号系统内部网络监测和故障诊断问题,能够提升系统的可视化和维护水平。
The maintenance terminal is an integral part of the high-speed railway signal system. It is an important means of system condition monitoring and maintenance, and also the carrier of system intelligent operation and maintenance technology. The computer interlocking system is a typical ground signal system. Based on the study of the network monitoring requirements of computer interlocking system, this paper uses graph theory model method to show the status of its host, internal network and external network channel. The problem of channel display is solved based on specific calculation method. Based on graph theory model and fuzzy reasoning, case-based reasoning analysis of typical switch fault and channel fault is carried out. It has been proved that the adaptive improvement of graph theory and reasoning can solve the complex problems of network monitoring and fault diagnosis in the signal system of high-speed railway, and improve the efficiency of visualization and maintenance of the system.
