2, use the data pin power supply of RJ-45 interface, 1,2 pin and 3,6 pin can be any polarity, as shown in Figure 2, because the DC(direct current) and data frequency do not interfere with each other, so, can while transmission current and data with a pair of line.
Present POE is the international standard IEEE 802.3af(15.4W according to two maturations substantially) and IEEE802.3at(25.5W).Because standard does not allow to use simultaneously above two kinds of electric power thus supplied, the PSE power supply unit is only supported wherein a kind of supply power mode, is equivalent to only utilize a port power supply.So the power of PSE power supply unit output is the highest to reach nearly 30W only, does not satisfy people gradually to more high-power demand.
[utility model content]
The technical problem that the utility model need solve provides a kind of power stage PSE power supply unit high, easy to use.
According to the above-mentioned technical problem that needs solution, the utility model has designed a kind of PSE power supply unit, comprise main control board and RJ-45 interface, also be provided with the first circuit buckle and the second circuit buckle that link to each other with main control board respectively in the described PSE power supply unit, thereby the idle pin of described the first circuit buckle and RJ-45 interface is electrical connected by idle pin output voltage, thereby the signal pins of described second circuit buckle and RJ-45 interface is electrical connected by data pin output voltage.
The utility model also provides a kind of POE system, and it comprises above-mentioned PSE power supply unit and PD power receiving equipment.
The utility model is in the situation that does not increase cost and do not change former instinct and satisfy under the prerequisite of international standard IEEE802.3af (15.4W) and IEEE802.3at (25.5W), in the PSE power supply unit, set up two circuit buckles, two circuit buckles can be simultaneously provide power supply for idle pin and data pin, like this, the power of output can reach 60W, thereby satisfies user's demand.

[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 3, the utility model POE system comprises PSE power supply unit and PD power receiving equipment.The interface of PSE power supply unit and PD power supply unit is the RJ-45 interface.Be provided with main control board in the PSE power supply unit, main control board manages, detects and power the PD power receiving equipment.
When the PSE power supply unit was the PD supplying power for powered device, its step comprised:
1. detect: at the beginning, the PSE power supply unit is at the very little voltage of port output, until its terminal that detects cable is connected with the PD power receiving equipment of supporting the IEEE802.3af/at standard.
2. classification: after detecting the PD power receiving equipment, the PSE power supply unit can be classified for the PD power receiving equipment, and assesses the required power loss of this PD power receiving equipment.
3. begin power supply: within the starting period of a configurable time (being generally less than 15 μ s), the PSE power supply unit begins to power from low-voltage to the PD power receiving equipment.
4. power supply: for the PD power receiving equipment provides reliable and stable direct current.
5. outage: if the PD power receiving equipment disconnects from network, PSE power supply unit rapidly (generally within 300～400ms) stops to be the power supply of PD power receiving equipment, and whether the duplicate detection process connects the PD power receiving equipment with the terminal that detects cable.
The utility model is provided with the first circuit buckle and the second circuit buckle that is attached thereto respectively at the main control board of PSE power supply unit.
Thereby the idle pin of described the first circuit buckle and RJ-45 interface is electrical connected by idle pin output voltage, thereby the signal pins of described second circuit buckle and RJ-45 interface is electrical connected by data pin output voltage.
As shown in Figure 4, the first circuit buckle is given idle pin output voltage (namely to idle pin power supply), and the power near 30W can be provided, and the second circuit buckle also can provide the power near 30W to data pin output voltage (namely giving the power supply of data pin).At this moment, netting twine 1,2,3,5 and 4,5,6,8 give the DC/DC(DC-DC power supply of PD power receiving equipment simultaneously) module for power supply, the power that the DC/DC module of PD power receiving equipment receives is near 60W.
