Standby intrinsic other step or units.
PoE, in general can be there are five rank in classification, and different ranks corresponds to the different power consumption level of PD.This
The direct current that the PSE used in application is provided is usually by tri- kinds of 12V, 24V and 48V.A usual PD is connected to by the port PoE
After PSE, PSE is that PD power supply is divided into three steps, and the supply voltage provided in each step is all different, to provide 48V electricity
For the PSE of pressure:
1, detecting step, when detecting power receiving equipment whether legal (i.e. whether PoE compatible), supply voltage be 2.5V~
10V, the time of the process substantially continue 500ms.
In the step, PSE first can send a test voltage to detect 19k Ω to a 26.5k Ω common mode in PD
Resistance, detection mode are to be obtained with test voltage divided by test electric current.Test signal starts to be then lifted out 10V for 2.5V, this
It will be helpful to compensation cable direct impedance bring loss, because this cable longest is up to 100 meters.Come if PSE is detected
From the impedance of PD between 19k Ω to 26.5k Ω, it will continue to lift up voltage.If can't detect characteristic impedance, PSE will
It will not be powered on for cable.Zener diode in PD circuit can guarantee the interference of the not tested trial signal of system rest part.
2, classification step is classified to PD if PD is legal and (is divided into 5 grades according to the power of PD to be powered),
The supply voltage of classification stage PSE is 15-20V, and the time of the process substantially continues 500ms.
In the step, after detecting PD, PSE will apply the voltage of 15~20V to PD, and pass through measurement size of current
To determine the rank of PD.If not finding other stage circuits other than the resistance for detecting the first order, which is defined as
Zero level is other.In this stage, the power unit of PD will maintain passive states by undervoltage lockout circuit, so as to disconnecting switch grade, directly
It is completed to feature and classification stage, undervoltage lockout circuit is turned off when being lower than a certain setting voltage, is higher than the setting reaching
It is just connected when voltage certain numerical value.
3, energizing step carries out stable power-supplying after classification, stablizes in 48V, and the time substantially needed of powering is general
Less than 15 μ s.
In the step, after the completion of classification, within the starting period of certain time, such as less than in the duration of 15 μ s, PSE starts
It is proceeded as follows from low-voltage to PD:
Start to power, until providing the DC power supply of 48V.
Stable power-supplying: providing the direct current of reliable and stable 48V for PD, meets the power consumption that PD is no more than 12.95W.
The framework of the PD of double PoE power supply is illustrated separately below, please refers to Fig. 1 and Fig. 2, Fig. 1 is single PD chip
Power supply structure schematic diagram, Fig. 2 is the power supply structure schematic diagram of double PD chips, wherein two ports of PSE lead to respectively in Fig. 1
Two ports PoE that cable is connected to PD are crossed, are connected with a PD rectifier bridge, i.e. PD rectifier bridge 1 and PD on each port PoE
Rectifier bridge 2, the input current of two ports PoE are combined in Combining Circuit after passing through two rectifier bridges respectively, then close
Road electric current is input in PD chip, and the electric current exported from PD chip is directly that other devices in PD are powered；And in Fig. 2
Two ports of PSE pass through two ports PoE that cable is connected to PD respectively, and it is whole to be connected with a PD on each port PoE
Bridge, i.e. PD rectifier bridge 1 and PD rectifier bridge 2 are flowed, the electric current of each PD rectifier bridge output is input in independent PD chip, i.e. PD
Chip and PD chip 2, and the output electric current of two PD chips is powered after being combined again for other devices in PD.
As can be seen that the circuit of two rectifier bridges output is into combiner in Fig. 1, it may appear that the case where electric leakage, i.e., its
In, the electric current that rectifier bridge 1 exports can flow to the corresponding ports that PD rectifier bridge 2 flows back into PSE by Combining Circuit, similarly
The electric current that rectifier bridge 2 exports can also flow to the corresponding ports that PD rectifier bridge 1 flows back into PSE by Combining Circuit.To make
Resistance value obtained in PD detection process is not consistent with actual, and it is this be not consistent likely result in resistance value beyond presetting
Resistance range can not power on or the case where can not powering on for a long time so that detection does not pass through.And in Fig. 2, rectifier bridge 1
Output electric current is input in PD chip 1, and the output electric current of rectifier bridge 2 is input in PD chip 2, PD chip 1 and PD chip 2 it is defeated
Electric current is input in Combining Circuit out, at this point, can flow back into PD chip 1 and PD chip 2 from the electric current that Combining Circuit exports, such as
In Fig. 2 shown in dotted arrow, which can successively flow back into the corresponding ports that PD rectifier bridge 1 flows back into PSE by cable again, together
Sample, the electric current for flowing back into PD chip 2 can also flow back into the corresponding ports of PSE by cable, so that PD was detected
Resistance value obtained in journey is not consistent with actual, and it is this be not consistent likely result in resistance value beyond preset resistance model
It encloses, so that detection does not pass through, the case where can not powering on or can not power on for a long time.
To solve the above-mentioned problems, i.e. it is mutually dry to carry out PoE hand shaking simultaneously for solution PD two-port when double PoE power
The limitation problem that can not be powered on disturbed, is below illustrated the application architecture of the embodiment of the present application, referring to Fig. 3, Fig. 3 is this
The power supply system schematic diagram for applying for embodiment, is wherein connected with control equipment, two ports on PSE pass through net respectively on PSE
Line is connected to two ports PoE of PD.The control equipment controls the power supply of PD by controlling PSE.
Specific control process is described below, refers to Fig. 4, Fig. 4 is the confession for PoE of the embodiment of the present application
One embodiment figure of method for electrically, wherein including PSE and control equipment, this method can include:
401, PSE reports what is connected on the PSE to power on unsuccessfully the port PoE to control equipment.
Wherein, in this step, a Port detecting process has been carried out in PSE, and during being somebody's turn to do, PSE can detect all
It is connected to the PD of the port on PSE, the port of the corresponding PD of a port of PSE, the port PoE of PSE and the port PoE of PD
It is connected by cable, PSE can report all ports PoE that can not be powered on.
402, what control equipment reception PSE was reported powers on the unsuccessfully electricity port PoE.
Wherein, after having reported and powering on unsuccessfully the port PoE, the control equipment positioned at the upper layer PSE will receive to be reported PSE
Power on the unsuccessfully electricity port PoE, these can then be powered on unsuccessfully the electricity port PoE execute subsequent step.
403, the port PoE is powered on unsuccessfully described in the acquisition of control equipment powers on frequency of failure K.
Wherein, the K is the integer more than or equal to 0., in this step, control equipment needs power on unsuccessfully PoE to each
The frequency of failure K that powers on of port is obtained, this power on frequency of failure K acquisition modes can there are many, for example, being set in control
It is standby interior that a counter safeguard for each port PoE, control equipment receive every time report power on the unsuccessfully electricity end PoE
Mouthful, the counter is just added 1, control equipment can complete setting to the counter of each port PoE in configuration phase with PSE
It sets, in this case, acquisition powers on unsuccessfully the corresponding counting in the port PoE and can be obtained and power on frequency of failure K,；Certainly, there are also one
Kind of mode is that this counter is arranged in PSE, and PSE by each powers on mistake while reporting and powering on the unsuccessfully electricity port PoE
The frequency of failure K that powered on for losing the electric port PoE is reported together, and under this situation, control equipment is directly from received information from acquisition
Power on frequency of failure K.
It should be noted that powering on the number of frequency of failure K unconfined can't increase, and can be by the way that the first threshold is arranged
Value and second threshold are limited, and after acquisition powers on frequency of failure K, can also be carried out according to frequency of failure K is powered on
Whether subsequent setting keep out of the way duration the step of is executed, specifically, can also include following judgment step after step 403:
403a, judgement power on unsuccessfully the relationship for powering on frequency of failure K and first threshold and second threshold of the port PoE,
When powering on frequency of failure K less than or equal to first threshold, execute step 403b, when powering on frequency of failure K greater than first threshold and
When less than or equal to second threshold, step 403b is executed, when powering on frequency of failure K greater than first threshold, is then gone to step
403d。
The value of the electric frequency of failure K is set as K by 403b, control equipment.
When powering on frequency of failure K less than or equal to first threshold, the numerical value of electric frequency of failure K is K, for example, first
Threshold value is 10, K when being less than or equal to 10, and K is this value.
The value of the electric frequency of failure K is set as first threshold by 403c, control equipment.
Power on frequency of failure K greater than first threshold and be less than or equal to second threshold when, although it is actual power on unsuccessfully it is secondary
Number has increase, but the counting for powering on the frequency of failure is not increasing.
From step 403b and step 403c it is found that power on unsuccessfully the port PoE described in obtaining in control equipment powers on failure
After number K, when it is described power on frequency of failure K less than or equal to first threshold when, the control equipment is by the electric frequency of failure K's
Value is set as K, that is, as long as K is less than first threshold, every failure once can be carried out to the frequency of failure is powered on plus a processing；In addition,
When it is described power on frequency of failure K greater than preset first threshold and be less than or equal to preset second threshold when, the control equipment
The value of the electric frequency of failure K is set as first threshold, that is, if K has been added to greater than first threshold and less than the second threshold
When value, then this is powered on into the frequency of failure and be set as first threshold always.This mode can prevent the number excessive and integer set
The quantity of interior integer is excessive, occupies excessive control device resource.
The port PoE is powered on unsuccessfully described in 403d, control equipment generation can not power on reason and record log.
As can be seen that subsequent step just will not be executed again when powering on frequency of failure K greater than the preset second threshold
Duration is kept out of the way in rapid setting, but directly will record down power on unsuccessfully the port PoE can not power on reason, and be recorded as day
Will.
As can be seen that if will be considered that this powers on unsuccessfully the port PoE and may have when K has been added to greater than second threshold
Other problems, specifically, when it is described power on frequency of failure K greater than second threshold when, the nothing of the port PoE is powered on unsuccessfully described in generation
Method powers on reason and record log, that is, will be considered that this powers on unsuccessfully the port PoE and can not power on, and does not also trigger basis and power on mistake
Lose number K be it is described power on unsuccessfully the step of duration is kept out of the way in the setting of the port PoE, so that PSE will not be indicated according to keeping out of the way duration
It handles this and powers on unsuccessfully the port PoE.Likewise, the port that can not be powered on due to excluding a part, to reduce control equipment
The occupancy of computing resource.
It should be noted that for generated can not power on reason and record log power on unsuccessfully the port PoE, i.e.,
Just control equipment is reported to by PSE again, will not participates in powering again, that is, operated as long as this powers on unsuccessfully the port PoE without plug
When, even if control equipment receives the information that PSE is reported and will not go to obtain that this powers on unsuccessfully the port PoE powers on the frequency of failure
K is more not carried out subsequent setting and keeps out of the way duration.
404, control equipment powered on according to frequency of failure K be it is described power on unsuccessfully the port PoE and be arranged keep out of the way duration.
Wherein, the default product for keeping out of the way duration and collisions parameter a length of when keeping out of the way, the collisions parameter is the control
Control equipment is more than or equal to 0 and less than or equal to 2 from MKAccording to the one of preset rules selection in the integer set of -1 integer
A numerical value, the integer set power on frequency of failure K as the control equipment according to and generate, and the M is more than or equal to 1
Integer.
Wherein, preset keep out of the way duration can be PSE detection be connected to duration used in the receiving end equipment PD of PSE, to institute
It states PD classification duration used and powers on the sum of duration used to the PD, i.e., the default duration of keeping out of the way is PSE to even
The PD detection for being connected to PSE starts the required duration until to PD power supply.Therefore it is preset with this and keeps out of the way duration multiplied by integer
The collisions parameter of form is at least one and default moves back so that any two power on unsuccessfully the difference for keeping out of the way duration between the port PoE
Duration is kept away, enabling to collisions parameter different two to power on unsuccessfully will not clash between the port PoE, further solve
The problem of PD can not or cannot be powered on for a long time.
In addition, M is equal to 2K, the integer set includes 2KA different from 0 to 2K- 1 integer.I.e. for one
It powers on unsuccessfully for the K port PoE, it can be from 0 to 2K- 1 totally 2KOne is selected to join in a different integer as conflict
Number substantially reduces two and powers on unsuccessfully the port PoE and choose the probability of the same collisions parameter, in this way so that keeping out of the way setting for duration
It sets more reasonable, is further reduced the different conflicts powered on unsuccessfully between the port PoE.As can be seen that due in integer set
The quantity of certificate is 2KIt is a, therefore the algorithm used in step 403 to step 404 can be referred to as binary exponential backoff calculation
Method.
It should be noted that being to control equipment to be more than or equal to 0 and less than or equal to 2 from M for collisions parameterK-1
Integer integer set in a numerical value being selected according to preset rules, there are many mode of the preset rules, such as from integer
In set randomly choose one, such as once report it is multiple power on unsuccessfully the port PoE when, often power on unsuccessfully the end PoE for one
Mouthful selection collisions parameter is waited, and is just removed the value from integer set, to guarantee each to power on unsuccessfully the port PoE and selecting
Different collisions parameter, it can be seen that there are many kinds of the modes of the preset rules, and details are not described herein again, but a side in principle
