Research on node fault location method in optical fiber communication network

节点故障定位能够有效保证光纤通信网络,确保网络运行质量。针对故障定位不准确的问题,研究了一种新的光纤通信网络中节点故障定位方法。采取分布式故障数值处理方式,执行故障特征值标记代码指令,将代码指令发送至不同的数据节点中,在发送的同时构建指令存储区域,实现分布式处理操作,并将执行后的指令结果返回至中心处理客户端,进而避免因光线通信网络外部数据的干扰影响特征值数据的提取结果。根据获取的光纤通信网络节点故障特征值判断故障位置,并进行相应的故障定位处理,通过数据收集、故障预警数据相关处理、预警数据过滤、节点故障定位、无效定位数据传输管理实现故障定位。实验结果表明,研究的光纤通信网络中节点故障定位方法具有较高定位精准度,在信噪比为-8 dB时,其定位精准度达到98%,优于对比方法,且在定位过程中不会影响光纤通信网络的正常通信速度,有效保证网络的安全性能。

Node fault location can effectively guarantee the optical fiber communication network and ensure the quality of network operation. Aiming at the problem of inaccurate fault location, a new method of node fault location in optical fiber communication network is studied. The distributed fault numerical processing method is adopted, the fault characteristic value marking code instruction is executed, the code instructions is sent to different data nodes, the instruction storage area is built at the same time as the transmission, the distributed processing operations is realized,and the executed instruction results are returned to the central processing client, so as to avoid the interference of the external data of the optical communication network affecting the extraction results of the eigenvalue data. According to the obtained fault location characteristic value of the optical fiber communication network node, the fault location si judged, and the corresponding fault location processing is performed, and the fault location is realized through data collection, fault early warning data related processing, early warning data filtering, node fault location, and invalid location data transmission management. The experimental results show that the node fault location method in the studied optical fiber communication network has high location accuracy, And its location accuracy reaches 98% when the signal-to-noise ratio is-8dB, which is better than the comparison method. It affects the normal communication speed of the optical fiber communication network and effectively guarantees the security performance of the network.
