Abstract
The utility model discloses a novel redundancy power supply module for a light transmission platform frame. A frame power supply backboard is provided with a functional module direct-current/direct-current power supply transforming plug-in element and an alternating-current power supply module plug-in element; the novel redundancy power supply module is characterized in that: the frame power supply backboard is provided with the alternating-current power supply module plug-in element, including a main alternating-current power supply module plug-in element and a backup alternating-current power supply module plug-in element; and the frame power supply backboard is further provided with a group of external backup direct-current power interfaces. The novel redundancy power supply module for the light transmission platform frame ensures a hybrid fiber coaxial network apparatus to have the backup function of the alternating-current power supply and the backup function of the direct-current power supply simultaneously, effectively achieves the functions of both the alternating-current power supply and the direct-current power supply, and further has the advantage of being convenient for use and maintenance.
Description
Technical field
The utility model relates to Hybrid Fiber Coaxial (being called for short HFC-Hybrid Fiber Coaxial) transmission equipment technical field, is specifically related to a kind of new type light transmission platform frame redundant power supply module.
Background technology
In hfc plant, will use a large amount of optical transport platform frames, as power supply, installation and the webmaster etc. of various functional modules, the optical transport platform frame generally all is to use at indoor machine room; In order to guarantee the highly reliable work of network; Generally all adopt duplicate supply Hot Spare mode to work, each power module all is that 220VAC supplies power separately, one when breaking down therein; The work of another one automated back-up guarantees the frame operate as normal.
But along with networks development, the reliability requirement of network improves, another power module automated back-up when the backup of power supply should require one of them power module to break down; Power supply also can automatically switch on the direct current backup battery when requiring the power supply outage again; Just Virtual network operator should require power supply that the interchange backup functionality is arranged, and requires power supply that the direct current backup functionality is arranged again, and the frame of using in the present network all can not meet this requirement; Present frame generally can only be selected a kind of backup mode; Have the interchange backup functionality, or have the direct current backup functionality, can not the two take into account.
For solving above-mentioned deficiency of the prior art, the utility model provides a kind of new solution.
The utility model content
The technical problem that the utility model will solve is: the deficiency that is directed to prior art; A kind of new type light transmission platform frame redundant power supply module is provided; This new type light transmission platform frame redundant power supply module makes Hybrid Fiber Coaxial equipment have AC power backup functionality and DC power supply backup functionality simultaneously; Realized taking into account of the two effectively, also had and use and advantage such as easy to maintenance.
For reaching the foregoing invention purpose, the technical scheme that the utility model adopted is: a kind of new type light transmission platform frame redundant power supply module is provided, and frame power supply backboard is provided with functional module DC-DC power source conversion plug-in unit and AC power supply module plug-in unit; It is characterized in that: frame power supply backboard is provided with said AC power supply module plug-in unit, comprises that one is main with an AC power supply module plug-in unit and a subsequent use AC power supply module plug-in unit; On frame power supply backboard, also be provided with one group of external backup DC power supply interface.
Further, two groups of AC powers that said AC power supply module plug-in unit all is input 220VAC output 24V; Said external backup DC power supply interface is connected with outside 24V DC power supply.
In sum; The new type light transmission platform frame redundant power supply module that the utility model provided makes Hybrid Fiber Coaxial equipment have AC power backup functionality and DC power supply backup functionality simultaneously; Realized taking into account of the two effectively, also had and use and advantage such as easy to maintenance.
Description of drawings
Fig. 1 is the theory diagram of new type light transmission platform frame redundant power supply module.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to be described in detail:
As shown in the figure, this new type light transmission platform frame redundant power supply module, frame power supply backboard is provided with functional module DC-DC power source conversion plug-in unit and AC power supply module plug-in unit; It is characterized in that: frame power supply backboard is provided with said AC power supply module plug-in unit, comprises that one is main with an AC power supply module plug-in unit and a subsequent use AC power supply module plug-in unit; On frame power supply backboard, also be provided with one group of external backup DC power supply interface.
We change the traditional centralized power supply into decentralized power-supply; Because various functional modules generally all have several groups of power supplies (+24V/+12V/+5V); Traditional power module all is in a power supply, these several groups power supplies to be provided; But this must increase trouble for the direct current backup battery of frame, because the direct current backup can only be backed up one group of power supply.
And we just only are provided with one group of power supply+24V power supply at the frame backboard; Like this backup+the 24V DC power supply just directly is attempted by on the backboard of frame and gets final product; Two groups of also only single group+24V power supplies of Alternating Current Power Supply, other group power supplys that each functional module needs produce at inner DC-DC (DC/DC) conversion regime that adopts of functional module.Accomplish by two AC power supply modules when need exchanging backup like this, when needing the direct current backup by backboard external+the 24V completion of supplying power.
The power module of each functional module and Alternating Current Power Supply all directly is inserted on the backboard of frame; Direct external direct current backup+24V power supply from the backboard in addition; On backboard, has the automatic switch-over circuit of respectively organizing power supply, in the time of can accomplishing one of them AC power supply module damage, on another automaticallyes switch; During whole AC dump, on external+24V dc power supply automaticallyes switch.
Be convenient and produce that each functional module and power module all adopt the mode of direct plug, conveniently use and keep in repair.
In sum; Utilize this practical new type light transmission platform frame power supply backup module that provides to make Hybrid Fiber Coaxial equipment have AC power backup functionality and DC power supply backup functionality simultaneously; Realized taking into account of the two effectively, also had and use and advantage such as easy to maintenance.
Though describe in detail in conjunction with the embodiment of accompanying drawing, should not be construed as qualification to the protection range of this patent to the utility model.In the described scope of claims, various modifications that those skilled in the art can make without creative work and distortion still belong to the protection range of this patent.
