摘　　要：针对目前调度集中系统车务终端远近端通道缺少有效的监测手段问题,为进一步降低调度集中系统故障对行车安全的影响程度,深入研究并提出远近端通道监控单元设计方案。通过分析简单网络管理协议通信机制,明确在电务维护终端增加监控单元,主要包括代理进程、管理信息库、配置工具、告警通知、状态监视等模块。电务维护终端以用户数据报文协议方式实现交换机的数据配置、信息交互及处理、异常报警等功能,并能实时显示设备状态拓扑图。目前,该方案已在合肥段管内试用,应用效果良好,满足监控界面直观化和报警信息可视化等现场运维需求,可为调度集中系统故障处理提供参考。Due to the lack of effective monitoring methods for the remote and local channels of the Centralized Traffic Control(CTC)System,in order to further reduce the impact on traffic safety due to the CTC system failure,the design scheme of the remote and local channel monitoring unit is deeply studied and put forward.By analyzing the SNMP communication mechanism,it is made clear that the monitoring unit is added to the signal and communication maintenance terminal,which mainly includes the agent process,management information base,configuration tool,alarm notification,status monitoring and other modules.The signal and communication maintenance terminal realizes the data configuration,information interaction and processing,abnormal alarm and other functions of the switch in UDP mode,and can display the device status topology in real time.At present,the scheme has been piloted within the management area of the Hefei section,and the application has yielded positive results.The scheme meets the on-site operation and maintenance requirements such as monitoring interface visualization and alarm information visualization,and can provide reference for the fault handling of the CTC system.
