Optionally, for different power supply units, its first corresponding power receiving equipment can also be different, the most such as
The most above-mentioned power supply unit is Ethernet switch, and the first the most corresponding power receiving equipment can be that IP phone, network cameras etc. set
Standby.
Step 101 determining, the mode whether power supply unit and the first power receiving equipment connect can be by judging described confession
Whether data transmission procedure is established between electricity equipment and described first power receiving equipment.When described power supply unit is subject to described first
Electricity equipment can export certain information after connecting, in order to user may determine that described power supply unit and described first is subject to
Electricity equipment has been in connection status.Depending on described information can be according to practical situation, the present invention does not make concrete restriction.
If it is determined that if power supply unit and the first power receiving equipment are in not-connected status, need to check whether because of interface
Loosen or other reason causes described power supply unit cannot be connected with described first power receiving equipment.
When determining that power supply unit is connected with described first power receiving equipment, that can open described power supply unit supplies electric work
Energy.In order to preferably mate described first power receiving equipment and described power supply unit, described power supply unit can opened
First determine whether the power supply grade of described first power receiving equipment before function of supplying power, be defined as described first according to described power supply grade
The output power that power receiving equipment provides.Such as, it is judged that the power supply grade of described first power receiving equipment is the first estate, according to described
The output power that the first estate is defined as described first power receiving equipment and provides is first power corresponding with described the first estate.
For example, when the grade judging described first power receiving equipment is 0 grade, provide for described first power receiving equipment
The power of 13W.When the grade judging described first power receiving equipment is 1 grade, provide the merit of 15W for described first power receiving equipment
Rate.Judge the mode of the grade of described first power receiving equipment, can be control described power supply unit be described first power receiving equipment
Export different voltage, and record the response of the described first power receiving equipment described different voltages for receiving, such as described
Power supply unit be described first power receiving equipment output 10V voltage and described first power receiving equipment does not responds, when described power supply sets
First power receiving equipment described in during standby voltage for described first power receiving equipment output 20V produces response, then determine described first
The grade of power receiving equipment is the grade that input voltage 20V is corresponding, and the grade that different input voltages are corresponding here can pass through list
Mode record, after judging input voltage value, from list, directly find the output power of correspondence.Certainly can also there is it
The mode of its power supply grade judging described first power receiving equipment, the present invention does not make concrete restriction.
When power supply unit and described first power receiving equipment connect, and determine described first power receiving equipment power supply grade it
After, and when the function of supplying power of described power supply unit has turned on, the current powering mode that can control described power supply unit is first
Powering mode.
Needing exist for explanation, power supply unit is to have certain requirement, example for the starting current of power receiving equipment
As for part power receiving equipment, its starting current i.e. operating current is bigger, after it is connected with power supply unit, if power supply unit
If opening function of supplying power, power receiving equipment will start simultaneously, i.e. power receiving equipment initially enters power supply state, described power supply unit
Will be its power supply with the first powering mode.In this case power receiving equipment is considered standard power receiving equipment, described
First powering mode is standard powering mode.But for another part power receiving equipment, its starting current i.e. works electricity
Flow smaller, after it is connected with power supply unit, if if function of supplying power opened by power supply unit, power receiving equipment will not start, i.e.
Power receiving equipment does not enters power supply state.For this situation, owing to power receiving equipment is in non-power supply state, it is possible to
Determine whether whether it is non-standard power receiving equipment.
When opening function of supplying power, and after the current powering mode controlling described power supply unit is the first powering mode, inspection
Survey the current power supply state of described first power receiving equipment.When detecting that described first power receiving equipment is in power supply state, permissible
Determine that described first power receiving equipment is standard power receiving equipment, be that described standard device is powered by described first powering mode.
When detecting that described first power receiving equipment is in non-power supply state, it is judged that whether described first power receiving equipment is non-
Standard power receiving equipment.Here judge described first power receiving equipment be whether the mode of non-standard power receiving equipment can be by obtaining
The port current of described first power receiving equipment, it is judged that it is first pre-conditioned whether described port current meets, if meeting, the most permissible
Determine described first power receiving equipment criteria of right and wrong power receiving equipment.
Whether the above-mentioned port current judging described first power receiving equipment meets pre-conditioned can be to judge described first
Whether the port current of power receiving equipment is less than preset value, and described preset value can be 10ma, it is also possible to be other value.When judging
The port current of described first power receiving equipment is less than after preset value, it may be determined that described first power receiving equipment is non-standard to be set by electricity
Standby.
Arriving here, step 101 is finished, and i.e. determines that power supply unit and the first power receiving equipment connect and described power supply unit
Function of supplying power have turned on, but the described first current power supply state of power receiving equipment is in non-power supply state and determines described first
Power receiving equipment is non-standard power receiving equipment.Then start to perform step 102, will described power supply unit current powering mode by
First powering mode switches to second powering mode different from described first powering mode；So that described power supply unit is with described
Second powering mode is that described first power receiving equipment is powered；
Optionally, in step 102, the first powering mode is when described power supply unit and described first power receiving equipment are in even
When connecing state, in described power supply unit, the detection chip for the starting current that detects described first power receiving equipment is defaulted as enabling
The powering mode of the state opened.
Optionally, in step 102 second powering mode for being set described power supply unit being used for detect described first by electricity
The detection chip of standby starting current switches to the powering mode of disabled status from opening.
Need exist for explanation, under normal circumstances, when power supply unit and the first power receiving equipment connect, and open power supply
After function, the detection chip in power supply unit can detect the starting current of described first power receiving equipment, when the startup detected
When current ratio i.e. belongs to standard power receiving equipment relatively greatly, can directly power for it.But when opening of the described power receiving equipment detected
Streaming current is less when i.e. belonging to non-standard power receiving equipment, and power supply unit will not be powered for described first power receiving equipment.Therefore take

The detection chip being used for detecting described first power receiving equipment starting current in Bei is switched to disabled state by the enabled state given tacit consent to,
I.e. control described power supply unit and do not detect the starting current of described first power receiving equipment but directly for described first power receiving equipment
Power supply.
Simultaneously need to explanation, the size of above-mentioned starting current and port current is identical.
For example, if the starting current of an IP phone i.e. running current is 5ma, when its with a power supply unit such as
When POE switch connects, find that described port current less than 10ma, then can determine that described by its port current of software detection
IP phone is non-standard power receiving equipment, at this moment can be controlled in described POE switch for detecting described IP phone by software
The POE chip of starting current is at disabled state.By such mode, POE switch can be controlled and do not go to detect institute
State the starting current of IP phone but directly power for described IP phone.

Extract power supply unit, can periodically obtain the port current of described first power receiving equipment, when continuously no less than twice acquisition
Described port current all meet second pre-conditioned time, determine that described first power receiving equipment and described power supply unit are in disconnection shape
State, switches to described first powering mode by described current powering mode from described second powering mode.
Need exist for explanation, be in the case of a non-standard power receiving equipment is powered at power supply unit, owing to adopting
Be the second powering mode, the detection chip of the most described power supply unit cannot detect described non-standard power receiving equipment startup electricity
Flow to and cannot judge whether described non-standard power receiving equipment is pulled out.If described non-standard power receiving equipment is extracted by user
, described power supply unit still can be continuously what the port at described non-standard power receiving equipment place was powered, the most described non-standard
The power supply grade of power supply unit is 1 grade, and the most described power supply unit can persistently export the power of 15W.In this case, if used
When another power receiving equipment is accessed described port by family again, if if another power receiving equipment described cannot support the power of 15W, that
Another power receiving equipment described will be caused damage.
Optionally, referred to herein as second pre-conditioned can be first pre-conditioned identical with above-mentioned, it is also possible to different.Example
As, periodically obtaining the port current of described first power receiving equipment, the cycle here can be to obtain one every 1s or 2s
Secondary port current, the concrete time cycle present invention does not make concrete restriction.Judge whether the port current every time obtained meets
Second is pre-conditioned, for example whether less than preset value.Here preset value can be 10ma can also be other value.When being no less than
The described port current of twice acquisition all meet second pre-conditioned time, determine described first power receiving equipment and described power supply unit
It is off, at this moment described current powering mode can be switched to described first power supply mould from described second powering mode
Formula.
