| With the dynamic development of the telecommunication industry，the fiber opticnetworks are growing larger and more complex. Besides, diversification of today’snetwork service types, and hardware problems such as fiber aging, are increasing thenumbers of network failure events daily. However, current error detection methodoperated manually has shown its inefficiency obviously due to high efficiency opticalnetworks needed by communication services.In consideration that the vector information of the planimetric position is related tothe location of the planar map closely in the layout structure of the optical fibernetwork, this paper makes full use of the superiority of GIS in the management of thegeographic data, and combines the characteristics of the Geographic distribution of theoptical fiber network, to design the automatic monitoring system based on GIS forfault of optical fiber transmission network.This paper introduces the overall scheme of the system, and set the functions, thearchitecture and the networks of the system. The main chapters discuss the researchand realization of the high precision and low power optical time domain reflectometer(OTDR), the integrated redevelopment based on component type development of GIS.The database management system is developed from Oracle, and Visual studio2010ischosen to develop the client software of the system.This system uses OTDR and optical power meter as the core unit to detect theerrors of the system, which acquires the optical fiber faults real-time by the opticalswitch and wavelength division multiplexing technologies. Then it transfers the data tothe data server for positioning analysis, tabulation and storage, which can display thereal-time graphics of exact location and the types of fiber fault point in GIS. Mydesign assures the recovery of network with the fastest speed and achieves theautomatic fault monitoring of optical fiber network by centralized intelligentmonitoring for the whole network. |
