Abstract
The present invention discloses a kind of Power over Ethernet single port extender of POE technology, it include: network interface input, the network data signals and 48V power supply that the network interface input is isolated are supplied to PD unit, received 48V power supply is respectively supplied to power supply processing unit and PSE unit by the PD unit, 48V is depressured and powers for 3.3V to network interface chip by the power supply processing unit, 48V power supply is converted into POE output by the PSE unit, network data signals signal after network processing unit is reinforced, can 100 meters of Primary Transmit down again.The limitation that traditional ethernet data transmission 100m can be broken through, making the electrical transfer distance of Ethernet is more than 200m or more, realizes the distance between to load PSE power supply unit and PD and extends to 200m or even farther.
Description
Technical field
The present invention relates to too net power supply technique field, in particular to the Power over Ethernet single port extender of a kind of POE technology.
Background technique
Power over Ethernet, it is to transmit DC power supply using existing network data cable, in the same of transmitting signal
When also send power supply to electrical equipment, such as wireless aps, IP phone and IP Camera, eliminate local power supply.Due to wireless
AP, IP phone and the first-class terminal device of network shooting are usually large number of, position is special, take electric difficulty, and deployment not only consumes
A large amount of manpower and material resources greatly increase networking old, and extend the construction time.
POE technology then passes through power supply unit remote power feeding, eliminates and all pacifies independent power supply in each end equipment and set
Standby problem, it is not necessary to it in use site is deployed with devices individual power-supply system, it can greatly less deployment terminal device
Wiring and management cost.
Currently, the transmission range of the twisted pair of ieee standard ethernet standard is limited within 100 meters, due to by ether
The limitation of net definitely transmission range, the transmission range of Power over Ethernet is also limited within 100 meters, but practical application scene,
Often there is the application demand greater than 100 meters.
Summary of the invention
For above-mentioned deficiency in the prior art, the present invention provides a kind of extensions of the Power over Ethernet single port of POE technology
Device can break through the limitation of traditional ethernet data transmission 100m, make the electrical transfer distance of Ethernet more than 200m or more, real
It is even farther that the distance between PSE power supply unit and PD load are now extended into 200m.
In order to achieve the above object of the invention, the technical solution adopted by the present invention are as follows:
A kind of Power over Ethernet single port extender of POE technology, comprising: network interface input, what the network interface input was isolated
Network data signals and 48V power supply are supplied to PD unit, and received 48V power supply is respectively supplied to power supply processing by the PD unit
48V is depressured and powers for 3.3V to network interface chip by unit and PSE unit, the power supply processing unit, and the PSE unit is by 48V
Power supply is converted into POE output, and network data signals signal after network processing unit is reinforced, can Primary Transmit 100 down again
Rice.
Preferably, the network interface input is RJ45 network interface.
Preferably, when transmission range is greater than 200 meters, multiple extender series connection.
Preferably, the power supply processing unit is DC-DC reduction voltage circuit.
The invention has the benefit that
The present invention connects PSE power supply unit by the port IN, and OUT terminal mouth connects PD load, when PSE power supply unit at
Function, for after powering on, extender directly takes electricity from cable, is not necessarily to external power supply to PD load, and one-in-and-one-out can easily extend mark
The distance of quasi- PSE power supply unit and PD equipment room data communication and POE power supply.The single port extender can be more according to conveying distance
Grade series connection, maximum can extend POE to 500 meters.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is PD element circuit figure and DC-DC circuit figure of the invention；
Fig. 3 is PSE element circuit figure of the invention；
Fig. 4 is network processing unit circuit diagram of the invention.
Specific embodiment
In order that the present invention can be more clearly and readily understood, following will be combined with the drawings in the embodiments of the present invention,
Technical scheme in the embodiment of the invention is clearly and completely described.
As shown in Figures 1 to 4, the Power over Ethernet single port extender of a kind of POE technology, comprising: network interface input, the net
The network data signals and 48V power supply that mouth input is isolated are supplied to PD unit, and the PD unit distinguishes received 48V power supply
It is supplied to power supply processing unit and PSE unit, 48V is depressured and powers for 3.3V to network interface chip by the power supply processing unit, institute
It states PSE unit and 48V power supply is converted into POE output, network data signals signal after network processing unit is reinforced, can be past again
Next stage transmits 100 meters.
The network interface input is RJ45 network interface.When transmission range is greater than 200 meters, multiple extender series connection.The power supply
Processing unit is DC-DC reduction voltage circuit.
The single port extender directly takes electricity from cable, is not necessarily to external power supply, and one-in-and-one-out can easily extend standard PSE
The distance of power supply unit and PD equipment room data communication and POE power supply.And it can extend PoE to 500 with plural serial stage, maximum
Rice.
The above description is only a preferred embodiment of the patent of the present invention, is not intended to limit the invention patent, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the invention patent within the spirit and principle of patent of invention
Protection scope within.
