Description
Technical Field
The invention belongs to the technical field of intelligent communication, and particularly relates to a transformer substation optical fiber fault positioning system.
Background
The optical fiber communication is used as a main transmission mode of the current power system, the application range is more and more extensive, the optical fiber communication realizes long-distance signal transmission, the performance of the transmission signal is stable, the network must be well monitored in order to ensure the stability of a circuit, and when the network breaks down, if the position of a problem light path cannot be effectively found, a great amount of time and economic loss are inevitably caused. At present, OTDR (optical time domain reflectometer) technology is mainly used for the positioning of fiber faults. The technology can effectively monitor the distance between a fault point and a monitoring point, but cannot display the spatial position (coordinate value) of the fault point, the complex trend of optical fiber embedding in a power system brings great difficulty to optical fiber fault rush repair, and in the actual PFTTH network optical fiber fault treatment, the traditional OTDR can not meet the requirements of multi-branch and one-way high-loss real-time online monitoring of an access network, and the condition of increased loss caused by delayed accident treatment due to the fact that the geographical position of the fault point can not be found quickly and accurately often occurs;
existing and known architectures require manual use of optical time domain reflectometry ("OTDR"), which is a measurement technique for quickly and efficiently diagnosing fiber equipment and identifying the location of fiber faults that reduce or otherwise degrade a transmission link. OTDR can be applied to faulty fiber links to locate faults such as fiber cuts, macrobends, etc. OTDR gives the optical distance from a fiber fault (called an event) of the source emitting the OTDR test signal. OTDR can be used to quickly and efficiently identify and map fiber fault locations when combined with geographic information system ("GIS") data about the physical routes of fiber optic equipment and knowledge of which customers lose communication with a central office providing communication services. Therefore, an effective fault diagnosis strategy utilizing the advantages of the OTDR helps to reduce the operation cost of the FTTP access network. However, existing OTDR-based techniques require a powerful manual intervention each time a fault is reported, where the technician uses OTDR for the fiber location, uses OTDR to identify the optical distance of the fault, and then maps the distance onto a GIS map to determine the location, since the difference of the optical distance from the actual physical distance makes it difficult for the technician to locate/correct the actual fault location/position.
