Virtual instrument based online monitoring, real-time detecting and automatic diagnosis management system for multi-fiber lines

Along with the popularity of the optical fiber communication, virtual instrument based online monitoring real-time detecting and automatic diagnosis management system on multi-fiber is proposed in this paper. To manage fiber lines and landmarks, simplified landmark map are presented based on the landmark list. Multi-fiber lines are online monitored, which may have the different or same parameters. When the optical power of any monitored line exceeds the set threshold, the subsystem gives a low power alarm, detecting subsystem will be started automatically to detect alarmed line. After data processing and analysis of detection results, then draws the result curve in the virtual instrument panel. User can locate plot of the curve, and zoom in event curve based on the event list. It utilizes detection results, event list, landmark list and simplified landmarks map synthetically, and presents comprehensive diagnosis conclusion of detection based on the map. To avoid fault, the system predicts fault in future through the analysis of a period of the historical detection result. This system has the advantages of excellent stability, powerful analysis, friendly interface, and convenient operation.
