Wherein, described power supply unit PSE monitors the power consumption of powered device PD in real time, and adjusts the output power distributing to powered device PD.
Introduce described control method separately below.
A kind of communication apparatus POE method for controlling power supply, the output power for POE system distributes；Including:
Powered device PD is connected with power supply unit PSE by netting twine；
Power supply unit PSE distributes specified output power according to the power type value of powered device PD to it；
Power supply unit PSE obtains the actual power consumption of powered device PD in real time, and using described actual power consumption as the rated power supply power of described powered device PD, performs powered operation.
Wherein, described power supply unit PSE monitors the power consumption of powered device PD in real time, and adjusts the output power distributing to powered device PD.When not changing PSE device output, by making full use of the output of PSE, provide electric power for PD equipment as much as possible.Thus can reduce the consumption that makes of PSE in whole system, the Meteorological of less PSE device, increase the service efficiency of PSE device, improve the benefit of single PSE device.
In order to ensure steady running and the safety of some important IP device of downstream；Each port that described power supply unit PSE is connected with described powered device PD arranges power supply priority；According to power supply priority, control the supply of electric power of port.By being that each PD equipment sets priority in PSE side, ensure that the PD equipment of high priority can continued power.Simultaneously when the PSE power provided changes, or when PD equipment has increase or reduces, it is possible to the priority according to PD equipment, ensure the equipment not power-off of high priority.
Specifically, when the actual power consumption of the power supply unit PSE all powered device PD connected is beyond the gross output S of power supply unit PSEwTime, the port keeping priority higher is powered.
The power supply priority of the described each port of power supply unit PSE, needs be configured and adjust according to actual power supply.
When the priority of two or more ports is identical, two sub-priority are set for said two or two or more port.
Further, when accessing new powered device PD in existing POE system, calculate the power summation S of all online powered device PD higher than described new powered device PD place port prioritywt；At Sw-SwtRated power supply power W be more than or equal to described new powered device PD1When, described power supply unit PSE powers to described new powered device PD.
Wherein, the power being initially allocated to described new powered device PD is its rated power W1；After powering on, with the actual power consumption of described new powered device PD for its rated power, perform powered operation.

Wherein, when the actual power consumption of the powered device PD that the priority of described dead electricity that and if only if is relatively low can distribute power less than or equal to described residue, again access.
Further, when the powered device PD that priority is higher disconnects for electrical connection, power supply unit PSE calculates the general power of online all powered device PD；The low priority powered device PD meeting condition of power supply restores electricity.
Obtain the concrete operations of the actual power consumption of power receiving equipment: obtain the voltage and current of powered device PD；Calculate the actual power consumption W of powered device PDr。
When powered device PD is connected to power supply unit PSE, first detect its legitimacy, then judge whether to power.The legitimacy detection of powered device PD is carried out according to IEEE802.3at standard.
The present embodiment provides a kind of concrete implementation method.
Set the gross output S of PSE devicew；This power comes from the hardware capabilities of PSE device.
The priority of the configuration each port of PSE, the priority that each port can be differently configured.When the priority of multiple ports is identical, system can carry out the division of two sub-priority automatically, for instance can set that the more little priority of port numbers is more high.
When a PD equipment is linked into PSE system, first PSE detects the legitimacy of this PD equipment, and the process of detection carries out according to IEEE802.3at standard.When detection by after, PSE device read PD equipment type.
Type according to PD equipment, the power W of one standard of PSE predistribution1To this PD.Port numbers according to this PD place, detects and calculates the power summation S of all online PD equipment higher than this port numbers priority simultaneouslywt.If Sw-SwtMore than W1, then mean that PSE can power to this PD, then PSE distributes W1Power give this PD.
After this PD device power, the voltage and current detecting this PD equipment that PSE is real-time, by the two value, PSE is obtained with the performance number W that this PD equipment is actually usedr.PSE adjusts its output power to this PD according to this value, and the power of use total for such PSE just decreases W1–Wr.That is PSE has had more W1–WrWatt available horsepower, and the power that this part has more just as residue general power for the PD being newly added or the rank PD equipment lower than oneself.
When a new PD equipment is linked into the PSE port of high priority, first PSE carries out actual consumption calculating and distribution.When PSE still also has dump power, remaining PD can be powered on successively by PSE according to priority, until the unallocated power of PSE cannot meet the requirement of PD equipment.After this process terminates, originally the PD equipment of power supply may be relatively low and lose electric power due to priority, this guarantees the port of high priority and can preferentially obtain electric power.
When the PD equipment that priority is high disconnects, PSE can recalculate the general power of online all PD, if also having remaining power, the equipment of those low priorities just can restore electricity again.
