Step 101, when needs are target P D equipment power supply, and residue output power consumption is less than this target P DWhen the work power consumption of equipment, judge in the PD equipment having powered on self connecting, whether exist opened attachedThe PD equipment of genus equipment. If so, go to step 102; Otherwise, finish current flow process.
In the embodiment of the present invention, said method can be applied the PSE equipment of supporting POE power supply, as NVR(NetworkVideoRecorder is network hard disk video recorder). For ease of describe, below with above-mentioned sideThe executive agent of method is that NVR is that example describes, but should be realized that PSE in the embodiment of the present inventionEquipment is not limited to NVR, and the embodiment of the present invention is follow-up no longer to be repeated.
In the embodiment of the present invention, target P D equipment does not refer in particular to a certain fixing PD equipment, but canTo refer to arbitrary PD equipment of access PSE equipment. Wherein, in the time that PSE equipment is NVR, this PDEquipment can be IPC (IPCamera, web camera), in embodiments of the present invention, establishes with PDStandby for IPC is that example describes, but should be realized that, in the embodiment of the present invention, PD equipment is not limited toIPC, the embodiment of the present invention is follow-up no longer to be repeated.
In the embodiment of the present invention, access by POE port when NVR detects Target IP C, and determineWhen this IPC supports POE power supply, NVR can estimate the work power consumption of this Target IP C, and judgement is surplusWhether remaining output power consumption is less than the work power consumption of Target IP C. Wherein, the work power consumption of Target IP C is orderIn basic power consumption (not opening the power consumption under auxiliary device state) and the Target IP C of mark IPC in openingThe power consumption sum of the auxiliary device of state.
Preferably, when IPC initially accesses NVR, can not open the arbitrary auxiliary device of self, with mostMay ensure that NVR has enough output power consumptions to meet the work requirements of IPC.
If NVR judgement residue output power consumption is less than the work power consumption of Target IP C, NVR can't be directStop for self connect powered on and lower (the Target IP C as relative in POE port numbers of priorityPOE port numbers is higher) IPC power supply, but need to first judge in the IPC having powered on self connectingThe IPC of auxiliary device has been opened in existence; Wherein, this auxiliary device can comprise that IPC is integratedThere is the auxiliary device (as infrared lamp) of infrared function or there is auxiliary device of heating function etc.
What deserves to be explained is, in embodiments of the present invention, when NVR need to be Target IP C power supply, andResidue output power consumption is less than the work power consumption of Target IP C, does not have the IPC that has opened auxiliary device simultaneouslyTime, NVR can refuse the power supply into Target IP C, or processes according to other strategy.
In addition, when NVR need to be Target IP C power supply, and residue output power consumption is more than or equal to targetWhen the work power consumption of IPC, NVR can be directly Target IP C power supply, or according to other strategy placeReason, the embodiment of the present invention does not limit this.
Step 102, judge the auxiliary device in opening power consumption sum and residue output power consumption itWhether be more than or equal to the work power consumption of target P D equipment. If so, go to step 103; Otherwise,Finish current flow process.
In the embodiment of the present invention, exist and opened when NVR judges in the IPC having powered on self connectingWhen the IPC of auxiliary device, the power consumption that NVR can further judge the auxiliary device in opening withWhether residue output power consumption sum is more than or equal to the work power consumption of Target IP C equipment, determines the portion that closesPoint or all the residue after the auxiliary device in opening export power consumption and whether meet for Target IP CWork power consumption demand.
In order to achieve the above object, in embodiments of the present invention, NVR need to be known going up of self connectingThe opening of the auxiliary device of the IPC equipment of electricity, and the power consumption of each auxiliary device.
As the optional embodiment of one, the method for supplying power to that the embodiment of the present invention provides can also comprise withLower step:
11), receive the logon message of the PD equipment that powers on self connecting, this logon message comprisesThe opening of the each auxiliary device of PD equipment and the power consumption of each auxiliary device power on;
12), record this the powered on opening of the each auxiliary device of PD equipment and merit of each auxiliary deviceConsumption.
In this embodiment, when IPC is by POE port access NVR, and NVR is successfully IPCAfter power supply, IPC can be according to opening (open or close), each attached establishing of self each auxiliary deviceThe information such as standby power consumption are carried at and in logon message, send to NVR; NVR receives after this logon message,Can obtain opening and each auxiliary device of each auxiliary device of the IPC carrying in this logon messagePower consumption, and record the opening of each auxiliary device of the IPC that powers on self connecting and each attachedThe power consumption of equipment, for example, NVR can safeguard an auxiliary device state power consumption table, auxiliary device stateEach list item of power consumption table records each auxiliary device of the IPC equipment that powers on of a NVR connectionMark (as numbering), power consumption and opening etc.
When NVR need to be Target IP C power supply, and residue output power consumption is less than the work merit of Target IP CConsuming time, NVR can be according to the opening of each auxiliary device of the IPC that powers on of self record and eachThe power consumption of auxiliary device judges whether the IPC that powers on self connecting exists the IPC that has opened auxiliary device,And whether the power consumption of auxiliary device in opening is more than or equal to order with residue output power consumption sumThe work power consumption of mark IPC.
Step 103, send auxiliary device to the part or all of PD equipment of having opened auxiliary device and closeInstruction, so that the residue output power consumption of auxiliary device after closing is more than or equal to the power consumption of target P D equipment;Wherein, auxiliary device out code is used to indicate the PD device shutdown of having opened auxiliary device in openingThe auxiliary device of state.
In the embodiment of the present invention, when NVR judges that in the IPC that powers on self connecting, existence has been opened attachedThe IPC of genus equipment, and the power consumption of auxiliary device in opening is greater than with residue output power consumption sumOr while equaling the work power consumption of Target IP C, NVR can be to the part or all of auxiliary device of having openedIPC sends auxiliary device out code, to increase residue output power consumption, ensures that the power consumption of residue output work is enoughMeet the work requirements of Target IP C.
Wherein, can comprise the mark (as numbering) of auxiliary device in auxiliary device out code, IPC connectsReceive after auxiliary device out code the auxiliary device that can comprise according to this auxiliary device out codeMark, close the corresponding auxiliary device in opening.
But what deserves to be explained is, in embodiments of the present invention, in auxiliary device out code, also can not wrapDraw together the mark of auxiliary device, in this case, after IPC receives auxiliary device out code, will closeClose self all auxiliary device in opening, its specific implementation does not repeat them here.
In the embodiment of the present invention, NVR instruction IPC needs after closing the auxiliary device in openingUpgrade the opening of the auxiliary device of the IPC that powers on self connecting of self record.
In the optional embodiment of one, IPC receives the auxiliary device out code that NVR sends,And after closing auxiliary device, can return to an auxiliary device to NVR and close response message, this is attachedBelong to the mark of having carried the auxiliary device of closing in this flow process in device shutdown response message, so that NVRUpgrade the opening of the auxiliary device of the IPC that powers on self connecting of self record.
It should be noted that in embodiments of the present invention, when NVR judges attached in openingWhen the power consumption of equipment is less than the work power consumption of Target IP C with residue output power consumption sum, close all placesIn the time that the auxiliary device of opening still can not meet the work requirements of Target IP C, NVR can be by allAfter the auxiliary device of opening cuts out, the more each IPC's having powered on connecting according to self is preferentialLevel, according to priority order (as the POE port numbers of IPC connection order from big to small) from low to highStop as priority is lower than the IPC power supply of the priority of Target IP C, until the residue output work of NVRConsumption is more than or equal to the work power consumption of Target IP C; Or NVR can also directly connect according to selfThe priority of the each IPC having powered on, stops as priority is lower than order according to priority order from low to highThe IPC power supply of the priority of mark IPC, until the residue of NVR output power consumption is more than or equal to Target IP CWork power consumption, and need not remove specially to close auxiliary device.
Wherein, when not existing priority lower than Target IP C in the IPC having powered on that NVR self connectsThe IPC of priority, or priority after all closing lower than the IPC of the priority of Target IP C can not be stillWhen Target IP C power supply, NVR can stop the power supply for Target IP C.
Step 104, be target P D equipment power supply.
In the embodiment of the present invention, when NVR establishes by closing the attached of the IPC having powered on self connectingStandby, residue output power consumption is more than or equal to after the work power consumption of Target IP C, NVR can attempt isTarget IP C power supply.

Correspondingly, the power supply plan that the embodiment of the present invention provides can also comprise the following steps:
21), receive self connect the PD equipment having powered on send auxiliary device open request, this is attachedBelong to mark and merit that opening of device request comprises the target auxiliary device of the PD device request unlatching that powers onConsumption;
22), judgement remains when it power consumption whether output power consumption is more than or equal to target auxiliary device; If so,Go to step 23; Otherwise, go to step 24;
23), allow this PD opening of device target auxiliary device that powered on;
24), forbid this PD opening of device target auxiliary device that powered on.
Concrete, in embodiments of the present invention, as IPC access NVR, and after powering successfully, if IPCWant to open certain auxiliary device, IPC can send auxiliary device to NVR and open request, this auxiliary deviceOpen in request and can comprise the auxiliary device (being called target auxiliary device herein) that IPC request is openedMark (as numbering) and power consumption.
NVR receive IPC send auxiliary device open request after, can relatively remain output power consumption andThe power consumption of the target auxiliary device that the request of opening of this auxiliary device comprises, if residue output power consumption is greater than orEqual the power consumption of target auxiliary device, residue output power consumption is enough to meet the work need of target auxiliary deviceAsk, NVR can return to the response that allows to open target auxiliary device to IPC, so that IPC opensTarget auxiliary device; Otherwise NVR can return to the response of forbidding opening target auxiliary device to IPC,Forbid that IPC opens target auxiliary device.
Further, as the optional embodiment of one, if residue output power consumption is less than, target is attached establishesStandby power consumption, before above-mentioned steps 24, can also comprise the following steps:
Step 221), judge self connect the PD equipment having powered in whether exist in openingAnd priority lower than the auxiliary device of the priority of target auxiliary device;
Step 222) if exist, send auxiliary device out code to corresponding PD equipment, untilResidue output power consumption is more than or equal to the power consumption of target auxiliary device;
Step 223) otherwise, determine and carry out the above-mentioned PD opening of device target auxiliary device of forbidding powering onStep.
At this embodiment, can pre-define the priority of each auxiliary device, as the POE end being connectedThe priority of the auxiliary device of the IPC equipment that slogan is little is higher than the large IPC of connected POE port numbersThe priority of the auxiliary device of equipment; Or, can be according to the working environment of IPC and auxiliary deviceFunction is determined the priority of auxiliary device, as when the time period of time in needs illuminations, as evening 8:00 to 6:00 in morning, and the priority of the auxiliary device of illumination functions is higher than auxiliary device of heating function etc.
Correspondingly, when NVR receives the unlatching of the auxiliary device for target auxiliary device that IPC sendsRequest, and residue power consumption is while being less than the power consumption of target auxiliary device, and NVR can first judge whether existence placeIn opening, and priority is lower than the auxiliary device of the priority of target auxiliary device; If there is NVRCan send auxiliary device out code to corresponding IPC, so that corresponding IPC closes attached accordinglyEquipment, improves residue output power consumption, until residue output power consumption is more than or equal to the merit of target auxiliary deviceConsumption; Otherwise NVR can forbid the unlatching of target auxiliary device.
Wherein, in this embodiment, NVR closes in opening, and priority is attached lower than targetBefore the auxiliary device of the priority of genus equipment, can also first judge that this is in opening, and priorityWhether the auxiliary device lower than the priority of target auxiliary device is more than or equal to residue output power consumption sumThe power consumption of target auxiliary device; If so, carry out above-mentioned closing in opening, and priority lower thanThe operation of the auxiliary device of the priority of target auxiliary device; Otherwise, forbid the unlatching of target auxiliary device.
Visible, in the described method flow of Fig. 1, when needs are Target IP C power supply, and remain defeatedWhen going out power consumption and being less than the work power consumption of Target IP C, can first attempt by closing attached in openingGenus equipment, instead of directly close the mode of IPC, improve residue output power consumption, to meet Target IP CWork requirements, under the fixing prerequisite of gross output, can be more IPC power supply as far as possible,Improve power supplying efficiency.
