光纤时间传递监控系统设计与实现

Design and implementation of optical fiber time transmission monitoring system

为了对现有的时间传递系统进行管理和控制,保障系统的灵活性、完备性、安全性和高可用性,设计了一整套光纤时间传递监控系统。在系统结构上采用集中式的结构,在功能上包括故障管理、性能管理、配置管理、安全管理和数据存储与管理5个部分,并对各个功能的具体实现方法作了详细的说明。监控系统对时间传递系统各节点进行集中管理和分散控制,并将获取到的数据存储在数据库中。最后在基于双向时分复用同纤同波的点对点时间传递系统上测试了监控系统,实验表明该系统能够对系统实时监控并对故障做出一定的处理,具有较高的可靠性。

In order to manage and control the existing time transmission system and ensure the flexibility,completeness,safety and high availability of the system,this paper designs a complete set of optical fiber time transmission monitoring system.A centralized structure is adopted in the system structure.In terms of functions,it includes five parts:fault management,performance management,configuration management,safety management,and data storage management.The specific implementation methods of each function are explained in detail.The system centralizes management and decentralizes control of each time transmission node at the monitoring node,and stores the data in the database.Finally,a monitoring system is tested on the point-to-point time transmission system based on BTDM-SFSW.Experiments show that the system can monitor the system in real time and deal with faults to a certain extent,which has high reliability.
