Embodiment

For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

The flow chart of the method for supplying power to that Fig. 1 provides for one embodiment of the invention.As shown in Figure 1, the method for the present embodiment comprises:

Step 10, electric controller obtain power and the power demand of every switch in current many switches.

The electric controller of the present embodiment can be to be independent of every switch, but the equipment being connected with every switch.In addition, the electric controller of the present embodiment can be also a switch in many switches.Wherein, when electric controller is a switch in many switches, also need to from current many switches, specify a switch as electric controller before this.The method of specifying electric controller from many switches can be human configuration, can be also to adopt dynamic election mechanism, by many switch automatic elections, is gone out.Wherein, when adopting automatic election mechanism, require every switch to connect mutually, and can communicate.

Before implementation step 10, every switch in frame need to be connected with electric controller, so that electric controller intercoms mutually with every switch.For example: can the communication interface of every switch be connected with the communication interface of electric controller by cable.For realizing technical solution of the present invention, the switch in various embodiments of the present invention is provided with the communication interface communicating with external equipment.

After every switch is all connected with electric controller, electric controller can initiatively be logined every switch, obtains power, power demand and the precedence information etc. of every switch.In addition, electric controller also can send acquisition of information instruction to every switch, by every switch, its power, power demand and precedence information etc. is sent to electric controller.

Wherein, the power of every switch refers to the power output of the power supply of every switch.When setting up switch, switch has been equipped with power supply if, and the power of this switch is the power output of the power supply being equipped with into this switch; If when setting up switch,, for this switch is equipped with power supply, the power of this switch is not 0.Whether the power demand of switch refers to the switch required power that works, no matter be that switch has been equipped with power supply, and switch has power demand.Every switch is pre-stored the information such as power separately, required power consumption and precedence information.

In the present embodiment, in many switches in frame, at least exist a power demand to be less than the switch of power.That is to say to have at least the power demand of a switch to be greater than its power.

Electric controller obtains power and the power demand of every switch, the power supply that can know not enough and poor how much power of the power supply of which switch, which switch has redundancy and how much power of redundancy, and then can also know that all redundant powers can provide the information such as output power for the switch of which power supply deficiency, the power supply of controlling after current parallel connection for follow-up electric controller lays the foundation to many power supply for exchange.

Step 20, electric controller are controlled power supply after current parallel connection to current many power supply for exchange.

In the present embodiment, in order to realize, power supply to be combined and distributes the object of using unitedly, before step 20, need the power supply of current existence to be together in parallel, and the power supply after parallel connection and every switch are coupled together.

Wherein, when the gross power of all power supplies is more than or equal to the power demand sum of all switches, electric controller is specifically controlled power supply after current parallel connection to all power supply for exchange.When the gross power of all power supplies is less than the power demand sum of all switches, electric controller can selectively be controlled power supply after current parallel connection to part power supply for exchange.

In the present embodiment, by current power supply is together in parallel, and be connected with every switch respectively, allow the output power of part switch to be less than its power demand, and the power supply of electric controller after controlling parallel connection is to the power and the power demand that first obtain current every switch before power supply for exchange, for the power supply of controlling after parallel connection lays the first stone to power supply for exchange, then control power supply after parallel connection to power supply for exchange, realized the power supply of many switches is combined and distributes use unitedly again, switch by the redundant power power division of part switch to power deficiency is used, reduced the redundancy of power, improved the utilance of power.

To illustrate the present embodiment below and there is above-mentioned beneficial effect: in the prior art, user is separately for every switch configuration power supply in frame, and the power output of its power supply is always slightly larger than the actual power demand of switch, the power that is assumed to be the power supply that every switch is equipped with will be at least compared with the large 25W of power demand, and the present embodiment adopts many power supplies to be together in parallel and distribute the method for use again, make user can take the power demand sum of all switches as according to being equipped with power supply, for example, when total power demand is 500W, can configure the power supply that total power output is 525W, total power redundancy is 25W, this is than for every switch is while being equipped with power supply separately, every switch has the power redundancy of 25W to compare, save a lot of powers, thereby improved the utilance of power.

In addition, by adopting the technical scheme of the present embodiment, when setting up new switch in frame, if the dump power of the power supply after current parallel connection meets the power demand of new switch, can be equipped with new power supply for new switch, to a certain degree solving and need to be equipped with the problem of new power because setting up new switch, not only can reduce the number of power sources of network computer room, but also reduced the energy waste that the poor efficiency of power supply when little load running causes, improved the utilance of power supply.

The flow chart of the method for supplying power to that Fig. 2 A provides for another embodiment of the present invention.As shown in Figure 2 A, the method for supplying power to of the present embodiment comprises:

Step 101, electric controller obtain power, power demand and the precedence information of every switch in current many switches.

The electric controller of the present embodiment can be to be independent of every switch, but the equipment being connected with every switch.In addition, the electric controller of the present embodiment can be also a switch in many switches.Wherein, when electric controller is a switch in many switches, also need to from current many switches, specify a switch as electric controller before this.The method of specifying electric controller from many switches can be human configuration, can be also to adopt dynamic election mechanism, by many switch automatic elections, is gone out.Wherein, when adopting automatic election mechanism, require every switch to connect mutually, and can communicate.

Before step 101, every switch in frame need to be connected with electric controller, so that electric controller intercoms mutually with every switch.For example: can the communication interface of every switch be connected with the communication interface of electric controller by cable.For realizing technical solution of the present invention, the switch in various embodiments of the present invention is provided with the communication interface communicating with external equipment.

After every switch is all connected with electric controller, electric controller can initiatively be logined every switch, obtains power, power demand and the precedence information of every switch.In addition, electric controller also can send acquisition of information instruction to every switch, by every switch, its power, power demand and precedence information etc. is sent to electric controller.

Wherein, the power of every switch refers to the power output of the power supply of every switch.When setting up switch, switch has been equipped with power supply if, and the power of this switch is the power output of the power supply being equipped with into this switch; If when setting up switch,, for this switch is equipped with power supply, the power of this switch is not 0.Whether the power demand of switch refers to the switch required power that works, no matter be that switch has been equipped with power supply, and switch has power demand.The precedence information of switch can carry out adaptability configuration according to the performance of switch, application scenarios etc. in advance.Every switch is pre-stored the information such as power separately, required power consumption and precedence information.

In the present embodiment, in many switches in frame, at least exist a power demand to be less than the switch of power.That is to say to have at least the power demand of a switch to be greater than its power.

Step 102, electric controller, according to the power of current every switch, power demand and precedence information, are determined target switch from current many switches.

In specific implementation process, electric controller is added the power of current every switch, obtains total power, and the power demand of current every switch is added, and obtains total power demand; Then judge whether total power is more than or equal to total power demand.If judgment result is that to be, illustrate that current power supply can provide power supply for all switches, therefore electric controller is determined current all switches, be target switch, by current all switches, form target switch.If the determination result is NO, illustrate that current power supply only can be for part switch provides power supply, therefore electric controller according to the precedence information of current every switch, from current many switches, selection portion minor exchange forms target switch.Now, the power demand of target switch is less than or equal to the power sum (being total power) of current many switches.Wherein, the result that in target switch, the power demand of every switch is added is the power demand of target switch.For example: electric controller can be selected switch successively according to priority order from high to low, until select again a switch will make the summation of the power demand of all switches of selecting be greater than total power.Again for example: electric controller can also be preferential according to priority selective sequential switch from high to low, but work as the power demand that dump power is less than next alternative switch, but while being greater than priority lower than the power demand of another switch of next alternative switch, can select this power demand to be less than the switch of dump power, to guarantee that power supply obtains the most effectively utilizing.

In this explanation, while conventionally initially setting up switch in frame, can be according to the power demand of every switch for configuring the power supply that can meet switch requirement.That is to say, when initially setting up switch, generally there will not be the situation that the determination result is NO.

The power supply that step 103, electric controller are controlled after current parallel connection is powered to target switch.

After determining target switch, electric controller just can be controlled power supply and power to target switch.

In the present embodiment, in order to realize, power supply to be combined and distributes the object of using unitedly, before step 103, need the power supply of current existence to be together in parallel, and the power supply after parallel connection and every switch are coupled together.For example: staff can be together in parallel each power supply by cable, and by switch, the power supply after parallel connection and every switch are coupled together.Wherein, the initial condition of switch is open mode, and the power supply after parallel connection can be to power supply for exchange; Only have when switch is selected as target switch, just closed by electric controller control switch, by the power supply after parallel connection to power supply for exchange.

Wherein, the control for the ease of electric controller to switch, the switch of the present embodiment is preferably various electronic switches.

In this explanation, by switch, the power supply after parallel connection being connected with every switch is a kind of mode that is comparatively easy to realization, but be not limited to this, every power supply after parallel connection can being connected with every switch, and the connected mode that the connected state between the power supply after parallel connection and every switch can be powered control appliance control is all within the scope of the present embodiment.

In the present embodiment, by current power supply is together in parallel, and be connected with every switch respectively, by electric controller, obtained again the power of current every switch, power demand and precedence information, and determine target switch according to the information of obtaining, then the power supply of controlling after parallel connection is powered to the target switch of determining, realized the power supply of many switches is combined and distributes use unitedly again, switch by the redundant power power division of part switch to power deficiency is used, reduced the redundancy of power, improved the utilance of power.In addition, by adopting the technical scheme of the present embodiment, when setting up new switch in frame, if the dump power of the power supply after current parallel connection meets the power demand of new switch, can be equipped with new power supply for new switch, to a certain degree solving and need to be equipped with the problem of new power because setting up new switch, not only can reduce the number of power sources of network computer room, but also reduced the energy waste that the poor efficiency of power supply when little load running causes, improved the utilance of power supply.

In this explanation, the situation that is all more than or equal to its power demand for the power of every switch in frame also can adopt the technical scheme of above-described embodiment, and the unified distribution again that combines of the power supply of every switch is used.

The flow chart of the method for supplying power to that Fig. 2 B provides for further embodiment of this invention.The present embodiment is realized based on Fig. 2 A illustrated embodiment, and as shown in Figure 2 B, the method for the present embodiment also comprises:

Step 201, electric controller obtain power demand and the precedence information of newly-increased switch.

The present embodiment emphasis is described in the handling process while newly setting up a switch (i.e. newly-increased switch) in frame.

In the present embodiment, when newly-increased switch, and directly unlike prior art for this newly-increased switch, be equipped with new power supply.But first will increase switch newly, be connected with electric controller, and by switch, the power supply after current parallel connection be connected with newly-increased switch.Now, the switch that connects power supply after current parallel connection and newly-increased switch is in open mode.

Then, electric controller obtains power demand and the precedence information of newly-increased switch.Acquisition methods can be referring to the description in step 101.

Step 202, electric controller, according to the power of every switch and the power demand of target switch before newly-increased switch, obtain dump power.

Then, electric controller is added the power of every switch before newly-increased switch, obtains total power; Then, the power demand of total power and current goal switch is subtracted each other, obtain dump power.Wherein, electric controller can store the total power calculating in step 102, and each so newly-increased switch can recalculate total power, but directly obtains stored total power.

Step 203, electric controller judge whether dump power is more than or equal to the power demand of newly-increased switch; If judgment result is that to be, perform step 204; If the determination result is NO, perform step 205.

After obtaining dump power, electric controller, by judging whether dump power is more than or equal to the power demand of newly-increased switch, judges whether current power supply can also be newly-increased power supply for exchange.

Step 204, electric controller are controlled power supply after current parallel connection to newly-increased power supply for exchange, finish this time operation.

When the power supply after current parallel connection is also enough newly-increased power supply for exchange, power supply and the switch between newly-increased switch that electric controller can directly be controlled after current parallel connection are closed, so that the power supply after current parallel connection is to newly-increased power supply for exchange.

As can be seen here, the present embodiment is used power supply by unified distribution, redundant power by the power supply after current parallel connection is newly-increased power supply for exchange, has avoided being equipped with for newly-increased switch the sequence of operations of new power supply, has improved the efficiency of setting up new switch.

Step 205, electric controller are again according to the power of current every switch, power demand and precedence information, from current many switches, redefine target switch, and control power supply after current parallel connection to the target switch power supply redefining out, and finish this time operation.

When current power supply deficiency is thought newly-increased power supply for exchange, electric controller, again according to the power of current every switch, power demand and precedence information, redefines target switch from current many switches.Now, current many switches comprise newly-increased switch.This operation specifically can be referring to the description of step 102.Wherein, the priority of newly-increased switch may be higher than being chosen as before the priority of the switch of target switch, newly-increased like this switch will newly be elected as target switch, thereby before replacing it, is chosen as the newly-increased low switch of priority of priority ratio of target switch.

Then, the power supply that electric controller is controlled after current parallel connection is powered to the target switch redefining out.This operation specifically can be referring to the description of step 103.

In this explanation, the present embodiment is particularly useful for the only system to power supply for exchange according to precedence information.

The method of supplying power to of the present embodiment, when newly-increased switch, first newly-increased switch and electric controller and current power supply after in parallel are coupled together, then by electric controller, obtained the power demand of newly-increased switch, again dump power is compared with the power demand of newly-increased switch, when dump power meets the power demand of newly-increased switch, directly the power supply after the current parallel connection of control is to newly-increased power supply for exchange, solve the problem that is equipped with new power supply for newly-increased switch, improved the utilance of power supply simultaneously.Further, when dump power does not meet the power demand of newly-increased switch, can again to the power supply after parallel connection, distribute according to precedence information, can make the switch that priority is high preferentially be served, the demand of realistic application.

The flow chart of the method for supplying power to that Fig. 3 provides for yet another embodiment of the invention.The present embodiment is based on realization embodiment illustrated in fig. 1, and as shown in Figure 3, the method for the present embodiment also comprises:

Step 301, electric controller obtain the power demand of newly-increased switch.

The present embodiment and Fig. 2 B illustrated embodiment are similar, are also that emphasis is described in the handling process while newly setting up switch in frame.

This step 301 is with the difference of step 201: electric controller only obtains the power demand of newly-increased switch, and does not need to obtain the precedence information of newly-increased switch.Other descriptions can be referring to the description of step 10 or step 201.

Step 302, electric controller, according to the power of every switch and the power demand of target switch before newly-increased switch, obtain dump power.

This step 302 can be referring to the description of step 202.

Step 303, electric controller judge whether dump power is more than or equal to the power demand of newly-increased switch; When judgment result is that while being, perform step 304; When the determination result is NO, perform step 305.

This step 303 can be referring to the description of step 203.

Step 304, electric controller are controlled power supply after current parallel connection to newly-increased power supply for exchange, finish this time operation.

This step 304 can be referring to the description of step 204.

Step 305, electric controller send the prompting message of newly-increased power supply.

This step 305 is distinguished to some extent with step 205.In the present embodiment, electric controller does not obtain the precedence information of newly-increased switch, therefore, when dump power is less than the power demand of newly-increased switch, electric controller directly sends and need to for newly-increased switch, be equipped with the information of new power supply, take and informs that the current power supply of staff cannot be newly-increased power supply for exchange again.

Compare with Fig. 2 B illustrated embodiment, once the present embodiment is particularly useful for powering on to switch, just do not allow in switch running the scene of electricity under switch.

The method of supplying power to of the present embodiment, when newly-increased switch, first newly-increased switch and electric controller and current power supply after in parallel are coupled together, then by electric controller, obtained the power demand of newly-increased switch, again dump power is compared with the power demand of newly-increased switch, when dump power meets the power demand of newly-increased switch, directly the power supply after the current parallel connection of control is to newly-increased power supply for exchange, solve the problem that is equipped with new power supply for newly-increased switch, improved the utilance of power supply simultaneously.Further, when dump power does not meet newly-increased switch, to staff, send information, so that in time for newly-increased switch is equipped with new power supply, guaranteed that newly-increased switch can put in use in time.

Further, on the basis of the various embodiments described above, electric controller can also detect the operating state of each power supply in real time, while having power supply to break down in the power supply after parallel connection being detected, whether the power after the power supply that electric controller judgement removal is broken down is more than or equal to the power demand of target switch.When the determination result is NO, electric controller is according to the precedence information of current every switch, again from current many switches, determine target switch, and control other power supplies of removing after the power supply breaking down and power to the target switch redefining out.When judgment result is that while being, electric controller can not carried out any operation.Wherein, electric controller can judge whether power supply breaks down by output state indication (Power Good) signal of each power supply of monitoring.When power supply lost efficacy (being fault), this signal will become high level, therefore, if electric controller monitors the output state index signal of certain power supply while becoming high level, just can judge corresponding power supply fault; Otherwise, can determine that power supply is normal.In this way, can be when power supply to break down, the use that adjust in real time power supply distributes, and when improving the utilance of power supply, guarantees that switch can normally carry out business as far as possible.

Below in conjunction with practical application example, technical solution of the present invention is described further.

Suppose: in same frame, assembled altogether 4 switches, its specification and power demand are as shown in table 1.

Table 1

Wherein, the summation of the power demand of 4 switches, be that total power demand is: 946+206+1646+576=3374W, but due to cannot be for every switch is equipped with the power supply with the close wattage of actual power demand, so the power sum of the power supply of these 4 actual outfits of switch is: 1100+300+1100+715+715=3930W.That is to say, the power supply of 3930W-3374W=556W is not utilized effectively and is idle in vain there.Now, if user will add a new switch in this frame, prior art can only newly be equipped with power supply and relevant power cable and socket for this new switch duplicate removal, and cannot utilize existing 556W power.And the present embodiment is by first combining the power supply of several switches with the form in power supply pond, to solve power supply utilance high and need to again be equipped with the problems such as power supply and power-supply wiring when being equipped with new switch for the method distributed unitedly again.The specific implementation principle of the present embodiment is as follows:

The power supply of each switch in same frame is together in parallel with cable.Wherein, suppose that these four switches are used Switching Power Supply, and all there is the slot of the plugged Switching Power Supply of standard.Wherein, each Switching Power Supply can convert the alternating current of 220V to the direct current of low-voltage.The direct current of the Switching Power Supply output of four switches is in parallel, and then distribute to every switch.That is to say, the direct current after parallel connection not only can be given this power supply for exchange, can also offer by external port other switches.Because the power demand sum of each switch is 3374W, and the gross power of power supply is 3930W.Adopt the method for the present embodiment, just the power supply of 300W in second switch can be saved, allow the power demand of a switch to be less than its power, make power supply utilance bring up to present 3374/3630=92.9% from original 3374/3930=85.8%.Meanwhile, remaining 256W power can also be for domination.If now need in frame to add the switch that a power is 200W left and right, so just can save the cost of buying new power supply and power supply being installed, can directly use remaining 256W power division to newly-increased switch.

In addition, while supposing to want to set up the switch of a 365W left and right in above-mentioned frame, because dump power is 256W, therefore the power supply that also needs to be equipped with more than 109W just can make the business of all switches all be achieved.The power supply that the present embodiment is a 350W of this system disposition is just enough to deal with problems, and the power supply redundancy that also has 241W, when supposing to need to increase new business or this system need to add new switch on follow-up second switch and the 4th switch, this part power supply just can offer needed place.
