Abstract
The invention discloses an SDH (synchronous digital hierarchy) remote supervision system for external RPR (resilient packet ring) of a substation. The system comprises a plurality of RPR-7610 devices and a plurality of SDH devices, VC-4 channels of each two adjacent SDH devices are set to be an unprotected link state, lateral bidirectional interfaces of the RPR-7610 devices are connected to two optical interface cards of each SDH device through optical tail fibers, and each two optical interface cards are serially communicated with two optical-direction optical fibers of the VC-4 channels, and thereby the SDH devices are connected to form a data communication ring network through the RPR-7610 device. The VC-4 channels among the SDH devices form the complete data communication network to provide a transmission and information exchange platform for various data services and high in reliability and efficiency and convenient to manage, wide space is reserved for future data service development, network upgrading expansion and the like, network utilization rate is increased, and original nodes which cannot transmit video signals due to insufficient bandwidth can be subjected to bandwidth expansion.
Description
One, technical field:
The present invention relates to a kind of network remote viewing system, particularly relate to the SDH remote viewing system of a kind of plug-in RPR of transformer station, utilize new network technology to improve the remote viewing system of transformer station.
Two, background technology:
In order to guarantee carrying out smoothly of production management work; Improve transformer station's video monitoring rate; Utilize new network technology to improve the remote viewing system of transformer station; Improve the image definition and the efficiency of transmission of video monitoring, make the situation of the reflection departures end that remote viewing system can be accurately and timely, so that relevant departments and the various cases of emergency of director's fast processing.Electric power system at present generally adopts core and the basis of SDH optical transport network as communication network.Because the development of mass data business is with universal, effectively the transmitting several data business becomes urgent and the necessary problem that solves on the SDH basic network.Novel resilient packet ring technology (being RPR) technology receives extensively attracting attention of industry as the up-to-date solution of MSTP (multiservice transport platform).
Three, summary of the invention:
Technical problem to be solved by this invention is: a kind of SDH remote viewing system that utilizes network technology to improve the plug-in RPR of transformer station of transformer station's video monitoring function is provided; Be used for improving the image definition and the efficiency of transmission of video monitoring; Make the situation of the reflection departures end that remote viewing system can be accurately and timely, so that relevant departments and the various cases of emergency of director's fast processing.
The technical scheme that the present invention is taked for the technical solution problem is:
The SDH remote viewing system of a kind of plug-in RPR of transformer station; Comprise a plurality of RPR-7610 equipment and a plurality of SDH equipment; VC-4 passage between adjacent two SDH equipment is arranged to unshielded Link State; Be connected to the side bidirectional interface of RPR-7610 equipment on two optical interface cards of SDH equipment through optical fiber pigtail; Two optical interface cards are ganged up respectively on the optical fiber of two light directions of VC-4 passage, connect according to this, through all RPR-7610 equipment all SDH equipment are connected to become a data communication link net.
The side bidirectional interface of said RPR-7610 equipment is a standard STM-1 standard interface.
The business interface of said RPR-7610 equipment is the 10M/100M user data interface.
Said RPR-7610 equipment is more than three or three; Said SDH equipment is more than three or three.
Positive beneficial effect of the present invention is following:
1, in order to improve transformer station's video monitoring rate; Utilize new network technology to improve the remote viewing system of transformer station; Improve the image definition and the efficiency of transmission of video monitoring; Make the situation of the reaction departures end that remote viewing system can be accurately and timely, so that relevant departments and director's fast processing, the present invention is through building up complete data communication network with the VC-4 channel group between the SDH equipment; High reliability, a high efficiency can be provided, manage the information platform of polytype data traffic transmission and exchange simply and easily; Reserved space widely for the development of following data service, network upgrade dilatation etc. simultaneously, improved the utilance of network, can also to originally because of the broadband deficiency can't transmission video signal node carry out the broadband and expand.
2, what nodes networking mode of the present invention owing to have all only take single VC-4 passage; Greatly saved the channel resource of SDH network; And because the two-way simultaneous transmission, the single-point available bandwidth is 310M, can significantly improve the broadband utilance through spatial reuse mechanism; Owing to adopt shared looped network transmission mode, can much more more to improve the broadband utilances again through statistic multiplexing mechanism.
3, the present invention makes data service when line faults such as fibercuts take place, obtain the not damaged transmission because RPR equipment provides less than 50 milliseconds of carrier class ring protection functions, guarantees the high reliability of network.
4, RPR equipment of the present invention can also carry out grade separation according to type of service, adds the fast development that ring is professional, for effective transmission of real time business provides guarantee.
