Description
Technical field
The utility model relates to a kind of optical cable on-line monitoring system in order to optical fiber state between each transformer station of fuzzy detection.
Background technology
Optical fiber communication is the communication mode using the fibre core in optical cable as transmission medium, and its advantage is that transmission capacity is large, and speed is high, and antijamming capability is strong, is one of mainstay of modern communications.Substantially all adopt optical fiber in network system intercommunication, and business all relating to the core business part of operation of power networks, is the important leverage of electric power netting safe running.
PDH optical transmission device is low due to cost, uses flexibly, widely applies in 35kV and following transformer station, power supply station.Current PDH light end equipment adopts point-to-point communication, cannot carry out webmaster on-line checkingi, also just cannot carry out on-line monitoring to transmission cable to it.Cause transformer station's various information to upload interruption, bring higher risk to the safe operation of electrical network.In recent years, the harm of outside destroy to optical cable presents the rising state of affairs, in order to the various electrical network business that energy real-time guard communications optical cable and optical cable transmit, needs to carry out Real-Time Monitoring to optical cable.Because the optical cable on-line monitoring equipment of specialty and system investments are very large, therefore need a kind of simple and reliable optical fiber monitoring device, Real-Time Monitoring is carried out to the state of intrasystem optical cable and optical fibres, guarantee that it is in safe operation state.
Summary of the invention
The purpose of this utility model is that proposing one guarantees that optical cable finds defect after breaking down as early as possible, rushes to optical cable accident approximate range place fast, for the optical cable on-line monitoring system gained time is claimed damages in accident treatment, accident investigation and loss.
The purpose of this utility model is achieved in that optical cable on-line monitoring system, comprise far end system and terminal system, it is characterized in that: described terminal system comprises webmaster display end and the SDH optical transmission device of series connection, described far end system comprises n of being installed on head end transformer station lightguide cable link optical cable sense terminals 11-1n in parallel, the SDH optical transmission device 1-n of n parallel connection, n optical cable sense terminals and n SDH optical transmission device one_to_one corresponding, each optical cable sense terminals SDH optical transmission device corresponding with it is connected, lightguide cable link in each middle transformer station after head end transformer station is equiped with optical cable sense terminals 21-2n respectively, until be equiped with optical cable sense terminals n1-nn respectively in each tail end power supply station.The cascaded structure between 11-n1 is formed, until the cascaded structure between 1n-nn by the optical cable sense terminals comprised in head end transformer station to the tail end power supply station arranged residing for it.
Owing to implementing technique scheme, the application gathers each supply station place optical cable information by optical cable sense terminals, then Information Monitoring is transferred to NM server, shows optical cable operation information, thus judge that whether optical cable is normal by webmaster display end.The application can carry out real-time optical cable detection when not affecting optical cable normal communication, the time that transformer station's various information is interrupted to minimum, will be improve grid equipment safety operation level, ensure that power network safety operation.
Accompanying drawing explanation
Concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is optical cable on-line monitoring system structural representation.
Embodiment
The utility model by the restriction of following embodiment, can not determine concrete execution mode according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, optical cable on-line monitoring system comprises far end system and terminal system, described terminal system comprises webmaster display end and the SDH(Synchronous Digital Hierarchy of series connection) optical transmission device, described far end system comprises n of being installed on head end transformer station lightguide cable link optical cable sense terminals 11-1n in parallel, the SDH optical transmission device 1-n of n parallel connection, n optical cable sense terminals and n SDH optical transmission device one_to_one corresponding, each optical cable sense terminals SDH optical transmission device corresponding with it is connected, lightguide cable link in each middle transformer station after head end transformer station is equiped with optical cable sense terminals 21-2n respectively, until be equiped with optical cable sense terminals n1-nn respectively in each tail end power supply station.The cascaded structure between 11-n1 is formed, until the cascaded structure between 1n-nn by the optical cable sense terminals comprised in head end transformer station to the tail end power supply station arranged residing for it.Wherein n is natural number.
Optical cable sense terminals in described far end system is responsible for optical cable status information capture, and multiple connection, line transmission and function of exchange combine together and transmit network by the integrated information of united net management Dynamic System by SDH optical transmission device 1-n.The multiple functions such as SDH optical transmission device 1-n can realize that network effectively manages, real time business monitoring, dynamic network are safeguarded, the intercommunication of different vendor's equipment room, can greatly improve network resource utilization, reduce administrative and maintenance expense, realize flexibility and reliability and the network operation efficiently and maintenance.
Described far end system is installed on one end of reserve cable, other end tail optical fiber by far end system jumper connection on the Optical Fiber Interface Board for subsequent use of the SDH optical transmission device in terminal system.
Fiber optic cable monitor terminal system by the optical cable status information transmission that collects to NM server, optical cable operation information is shown by webmaster display end, according to the optical cable information stored in grid service server, generate and store, show the logic analysis table of optical cable information, judge that whether optical cable is normal through contrast.
Described optical cable sense terminals is prior art, the non-the present application point of its technical characteristic, therefore does not elaborate to its concrete structure.
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
