Study on the Anomalous Node Location Method of Power Optical Fiber Communication Network Based on Adaptive Difference Resistance Filter
In order to solve the problem of low accuracy of abnormal node location in power optical fiber communication network,a method of abnormal node location in power optical fiber communication network based on adaptive robust filtering is proposed.Firstly,temporal redundancy algorithm is used to preprocess the node data of power optical fiber communication network,and the dynamic similarity and data link efficiency between nodes are extracted.Secondly,robust filtering is used to detect abnormal nodes and evaluate the mismatch between residual and prediction error in real time.Finally,combining adaptive filtering and change point detection,the accurate location of abnormal nodes in power optical fiber communication network is realized.The experimental results show that the research method can significantly improve the positioning accuracy of abnormal nodes in power optical fiber communication network and ensure the stable operation of the network.
