摘要
光纤通信信号一般具有复杂的低频成分,在通信信道中传输难以匹配信道特性,导致光纤通信故障诊断准确度不高,因此提出了一种基于载波调制的光纤通信故障数据诊断方法.该方法通过采集并预处理光纤通信信号,将采集信号加载到高频载波上实现载波调制,然后输入BP神经网络进行初步故障诊断.进一步利用换班测试法确定故障数据在通信链路上的位置.实验结果表明,该方法在实现光纤通信故障数据诊断的同时,能够准确定位故障数据在通信链路中的位置.
Abstract
Optical fiber communication signal generally has complex low frequency components,and it is difficult to match the channel characteristics in the communication channel,which leads to the low accuracy of optical fiber communication fault diagnosis.Therefore,an optical fiber communication fault data diagnosis method based on carrier modulation is proposed.By collecting and preprocessing optical fiber communication signal,the carrier signal is loaded on the high frequency carrier,and then input into BP neural network for preliminary fault diagnosis.Further use the shift test method to determine the location of the fault data on the communication link.The experimental results show that the proposed method can accurately locate the position of the fault data in the communication link while realizing the optical fiber communication fault data diagnosis.
