Description
Technical field
The present invention relates to the power system telecommunications technology field, be specifically related to a kind of network device.
Background technology
The passage of East China 500KV protection at present extensively adopts optical communication mode (comprising the special-purpose core mode of optical fiber and SDH circuit multiplexer mode), but because the optical cable condition is limit, most of optical fiber differential protective in fact still is carried on the same optical cable.Though Optical Transmission Network OTN has formed ring-type or network structure, because the protection mechanism of SDH self, looped network protection switching and path protection are switched and the inconsistent situation in sending and receiving letter path can occur under some particular cases, can not be applied to optical fiber differential protective.Recovery to be with the protection passage of the mode optical cable route of generally all taking to go directly, so the interruption of optical cables risk that causes circuit to lose protection is still objective reality.
Summary of the invention
The objective of the invention is to, provide the backup of a kind of dualization of relaying protection different network devices, solve above technical problem.
Technical problem solved by the invention can realize by the following technical solutions:
The network device that the backup of dualization of relaying protection is different; comprise A end protection equipment, B end protection equipment also comprises A end SDH channel unit, B end SDH channel unit; described A end SDH channel unit is connected by SDH digital multiplexing passage with described B end SDH channel unit
It is characterized in that described A end protection equipment connects described A end SDH channel unit by connecting A end channel switching device, described B end protection equipment connects described B end SDH channel unit by connecting B end channel switching device.
Described A end channel switching device directly connects described B end channel switching device by optical fiber designated lane ways of connecting.
Described A end channel switching device is connected local ethernet with described B end channel switching device by a HUB, described A end channel switching device holds channel switching device by the monitor terminal that described HUB is connected central station with described B, realizes the real-time monitoring to the communication port running status.
The present invention sends to offside with the passage of guard signal by different routes; when device normally moves; maintenance according to decision device operation and the passage switchover policy of monitor data intelligence, is carried out passage in case of necessity and is switched simultaneously the real-time monitoring of communication port running status.Switching device shifter has been finished the function of opto-electronic conversion and channel protocol conversion simultaneously, can replace the photoelectric conversion device of respectively protecting producer's correspondence at present.
Do not need original protection equipment or communication system are transformed, only need install switching device shifter simply additional, just can make the protection passage of original single route possess " double route " operation, the reliability of protection passage is significantly improved.This mode improvement cost is low, applied widely, site operation is also comparatively simple, can be widely used in " double route " transformation to the relay protection channel of each electric pressure.
Described optical fiber designated lane is made up of optical fiber and the optical signal transceiver equipment of special use, utilize the direct digital code stream that transmits through the representative current sampling data of ovennodulation of optical fiber, be a kind of digital channel of special use, its time delay depends primarily on length and the transceiver processing time of fibre circuit.Optical-fiber time-delay basic fixed under the situation that fibre circuit length is determined, the transceiver processing time is also fixed under the condition of proper communication, is a kind of desirable pilot wire relays passage.
Described SDH channel unit is a kind of of digital multiplexing passage, and the digital multiplexing passage relies on existing digital communications network (fiber optic network, digital microwave network) to form, and often adopts multiple communication system (PDH, SDH etc.).Different with the optical fiber designated lane, the digital multiplexing passage adopts multiplex mode and other professional common share communication bandwidth resources usually as a road in broadband, the multiplex communication.Common digital multiplexing channel type has N*64K passage, 2M passage etc. at present, also might occur the passage of forms such as ATM, Ethernet, IP in the future.The composition of digital multiplexing passage is very big because of the different difference of channel type, support network, communication mode, degree of share, and its passage constitutes very complicated, and the factor that influences the signal delivery lag is numerous.
In the middle of the practical application, according to the transmission range difference, need the flexible configuration channel type, adopt the optical fiber designated lane directly to connect between the factory station of general close together, and the general SDH digital multiplexing passage that adopts in distance area far away, the network topology more complicated.
Described A end channel switching device and described B end channel switching device all adopt and comprise a protected data interface module, a communications line interface module, also comprise the modularized design of a main control module, described protection interface module can compatible auspicious guarantors that continue in south, equipment is protected from, dark main flow such as auspicious in four directions, south, changes corresponding interface module according to docking producer; Described communications line interface module can compatible to SD H digital multiplexing passage and optical fiber designated lane mode, flexible configuration.
Beneficial effect: owing to adopt above technical scheme; the present invention does not need original protective device or communication system are transformed; only need install switching device shifter simply additional; just can make the protection passage of original single route possess " double route " operation, the reliability of protection passage is significantly improved.This mode improvement cost is low, applied widely, site operation is also comparatively simple, can be widely used in " double route " transformation to the relay protection channel of each electric pressure.
