Abstract
The invention relates to a method for Cable Bridge device supplying power via coaxial cable, which includes Cable Bridge Modem, power switcher, power distributor, power mixer, Cable Bridge Switch, and said Cable Bridge Modem, power switcher, power distributor, power mixer, Cable Bridge Switch are connected by Coax in turn, the low voltage direct current generated by said Cable Bridge Modem and the network data signal are mixed via power switcher and transmitted to the power distributor, and the power distributor mixes multiplex uploading signals, and the mixed signal is transmitted to the power mixer, the power mixer separates the lower voltage direct current from said mixed signals, and the lower voltage direct current is transmitted to supply power for Cable Bridge Switch. Comparing with present technique, the invention makes the Cable Bridge Switch device which needs supply power in outside of corridor not need other power supply, and simplify the construction work.
Description
Technical field
The present invention relates to a kind of method of supplying power to of broadband device, particularly relate to the method for cable bridge (Cable Bridge) equipment by coaxial cable (Coax) power supply.
Background technology
Its networking of existing cable TV network is adopted passive device mostly at the finger assignments net near user side, having only the amplifier of prolongation is active equipment, adopt the method for powering on the coaxial wire, from the image intensifer of local side is its power supply, like this cable TV network of whole community corridor does not need external power supply, and its structure as shown in Figure 1.
Cable Bridge (cable bridge) provides the new network equipment of home network interconnect function.It uses the above frequency of 860M, allows the user to set up the home network of bandwidth up to 270M on family's existing wired camera cable.Simultaneously, the user needn't worry to destroy or disturb original cable TV signal again.
Cable Bridge can provide high speed broadband service as a kind of novel coaxial cable high speed transmission technology on coaxial cable.But the equipment of Cable Bridge all is active equipment, will produce a powerup issue, and especially Cable Switch equipment is its power supply because physical location in corridor, need draw a power line in addition.If adopt the mode of the line powering of original cable TV, various active equipments to CATV are powered, after TV signal and low-voltage DC (being generally 60V) passed through electric splitter, send into Cable and be sent to the electric splitter of mistake of user side, crossing electric splitter separates CATV signal wherein with low-voltage DC, wherein the CATV signal continues transmission, and low-voltage DC powers then for Cable Bridge Switch, as shown in Figure 2.
But adopt the mode of this line powering, need to change original inactive component of existing finger assignments net, cost is very high.And Cable Bridge equipment is mainly used in the high speed data transfer in the home network, if adopt the mode of external power supply, just need carry out the external power supply of 220V, and this will increase the cost and the difficulty of construction.
Summary of the invention
Purpose of the present invention is exactly to provide the method for a kind of cable bridge device by coaxial cable power supply for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: cable bridge device is by the method for coaxial cable power supply, it is characterized in that, comprise Cable Bridge (cable bridge) Modem, cross electric splitter, cross electrical distributor, cross electric mixer, Cable Bridge Switch, described Cable Bridge Modem, cross electric splitter, cross electrical distributor, cross electric mixer, Cable Bridge Switch connects by Coax (coaxial cable) successively, low-voltage DC that described Cable Bridge Modem produces and network data signals were transferred to electrical distributor by crossing after electric splitter mixes, cross electrical distributor multichannel is uploaded the signal mixing, mixed signal was transferred to electric mixer, by crossing electric mixer low-voltage DC is separated from above-mentioned mixed signal, and low-voltage DC is transferred to Cable Bridge Switch is its power supply.
Be about to the CATV signal of network data signals, low frequency of high frequency under the electric mixer of described mistake and mix, on be about to network signal and separate with direct current.
Described Cable Bridge Modem converts outside 220V high-tension electricity to low-voltage DC by the AC/DC adapter of inside.
Described low-voltage DC can be according to the equipment requirements adjustment, as 36V.
Described 36V direct current is converted to little low-voltage DC by the DC/DC transducer, as 3.3V.
Compared with prior art, a kind of cable bridge (Cable Bridge) equipment that adopts above technical scheme has characteristics such as cost is low, resource utilization is high, power saving by the method for coaxial cable (Coax) power supply.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is another kind of prior art constructions schematic diagram;
Fig. 3 is a structural representation of the present invention;
Fig. 4 is a Cable Bridge Modem power supply schematic diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 3, cable bridge device is by the method for coaxial cable power supply, the Cable BridgeModem of user inside produces low pressure 36V direct current, sends on the Cable after passing through electric splitter acting in opposition, oppositely is sent to outdoor Cable Bridge Switch again and is its power supply.
Wherein, cross the 36V low-voltage DC that electric splitter produces Cable Bridge Modem and upload signal and mix upwards transmission of back.After crossing electrical distributor multichannel being uploaded signal (comprising the CATV signal) and mixed, continue upwards transmission.Cross electric mixer with the 36V low-voltage DC, from separating by crossing the electrical distributor signal that upwards transmission comes, and it is passed to Cable Bridge Switch is its power supply.
As shown in Figure 4, the method for supplying power to of Cable Bridge Modem, Cable Bridge Modem converts outside 220V high-tension electricity to low pressure 36V direct current by its AC/DC adapter.Wherein the 3.3V direct current is powered as himself, and 36V is sent on the Cable, realizes the function of POC (POWER OVER CABLE).
