The every other embodiment obtained, broadly falls into the scope of protection of the invention.
As it is shown in figure 1, a kind of method embodiments providing battery redundancy, it is applied to CPLD
(Complex Programmable Logic Device, CPLD), can include following
Step:
Step 101: described CPLD respectively with outside PSU (Power Supply Units, power supply),
Outside outside BBU (Battery Backup Units, battery back unit) is corresponding with described PSU
Portion's the first switch module, the outside second switch module corresponding with described BBU are connected, and pre-set

A kind of method embodiments providing battery redundancy, CPLD is determining that power supply occurs in PSU
During fault, within the time period set in advance, first send to the switch module corresponding with PSU and close
Instruction is to control it as off-state；Send to BBU to open the most respectively and enable signal to be controlled
It is made as power supply state, sends open command with the company of controlling it as to the switch module corresponding with BBU
Logical state, thus switch to BBU to power powering mode.Due to when there is power supply trouble in PSU,
Corresponding control instructions can be sent by CPLD order to BBU and two switch modules, controlling it be
Corresponding state, thus complete powering mode and supply power to, from PSU, the automatic switchover that BBU powers.Therefore,
The embodiment of the present invention can be when there is power supply trouble in PSU, it is ensured that server normally works.
In a kind of possible implementation, in order to illustrate when the power supply trouble of PSU eliminates, mould of powering
The switching of formula realizes process, so, farther include:
Pre-set for the second time period；
When the described power supply trouble determining described PSU eliminates, within described second time period, to described

For connected state.
In a kind of possible implementation, in order to avoid power-off occurring in powering mode handoff procedure
Risk, need to quickly transmit coherent signal, so, described first time period includes: 20～100ns.
In a kind of possible implementation, in order to illustrate that a kind of common CPLD determines that PSU occurs
The mode of power supply trouble, so, described determine that power supply trouble occurs in described PSU, including: receiving
When the abnormal electrical power supply that described PSU sends enables signal, determine that power supply trouble occurs in described PSU.In detail
Ground, it can be fault signal that described power supply enables signal.
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawings and specifically real
The present invention is described in further detail to execute example.
As in figure 2 it is shown, the method that one embodiment of the invention provides battery redundancy, the method can be wrapped
Include following steps:
Step 201: set up respectively the corresponding switch P of CPLD with PSU, BBU with PSU and
The annexation of switch B corresponding for BBU, sets up switch P Yu PSU respectively, is powered equipment
Annexation, the annexation set up respectively and switch B Yu BBU, being powered equipment, and set up PSU
Annexation with BBU.
In detail, P with PSU is corresponding for switch, therefore when the equipment of being powered is powered by PSU,
Need to ensure that switch P is in connected state.Accordingly, B with BBU is corresponding for switch, therefore works as BBU
When the equipment of being powered is powered, need to ensure that switch B is in connected state.
In detail, PSU can be server board level power supply.Accordingly, the equipment that is powered can be service
Any one or more in device is powered module.
In the present embodiment, BBU may be located in PSU, for example, it is possible to BBU is arranged on PSU
Internal.In a kind of possible implementation, BBU can be equally located on outside PSU.
The battery redundant fashion that the embodiment of the present invention provides, is that PSU is superfluous with the power supply of rechargeable battery BBU
Remaining, rather than the power supply redundancy between multiple PSU.The power supply redundant fashion of PSU Yu BBU, Ke Yiying
For without configuring multiple PSU, but it is likely to occur this application scenarios of power-off or PSU faults itself.
BBU is when power supply trouble occurs in PSU, it is possible to the equipment of being powered carries out normal power supply, does not affect clothes
The normal work of business device.And the price of BBU is low compared with PSU, compared with redundancy of powering with many PSU, PSU
Decrease with the power input cost of redundant fashion of BBU.
Additionally, due to BBU can be arranged on inside PSU, therefore for the clothes of available finite volume
Business device, in the case of not affecting server external structure and intraware fixed position, equally profit
With the BBU in PSU, it is achieved the power supply redundancy of this server, to ensure that it is when PSU power supply trouble
Can normally work.
In the present embodiment, the foundation of above-mentioned various annexation can be able to reality by board built-in circuit
Existing.For example, it is possible to the PSU by CPLD, comprising BBU, switch P, switch B and be powered equipment
It is arranged on same board, and sets up corresponding annexation by board built-in circuit.
Step 202:CPLD arranges first time period and the second time period.
In the present embodiment, the second time period can be identical with first time period, such as, be 20～
100ns.This time period can be configured according to the actual requirements.
When power supply trouble occurs in PSU, in order to not affect the normal work of server, need CPLD fast
Send and enable signal to BBU, switch P and switch B, to realize the quick power supply of BBU fastly.Cause
This, the transmission of signal can be that nanosecond is other, and such as, CPLD can send letter in 20～100ns
Number.
In the present embodiment, the signal that CPLD sends can be that high level enables signal.
Step 203: when PSU monitor power supply trouble occurs time, stop in first time period being supplied
Electricity equipment is powered, and sends fault signal to CPLD.
In detail, power supply trouble can include power-off, and/or, PSU faults itself.
Specifically, PSU can comprise a monitoring means, for monitoring whether that power supply event occurs in real time
Barrier.Power supply trouble occur when detecting, during such as unexpected power-off, PSU mono-aspect can stop exporting electric current,
I.e. stop by switch P circuit, the equipment of being powered being powered；Send to CPLD the most simultaneously
Fault signal.
Step 204:CPLD receive PSU send fault signal time, in first time period to
Switch P sends closing control instruction.
In the present embodiment, CPLD is when receiving the fault signal that PSU sends, it may be determined that PSU
Power supply trouble occurs.
Additionally, CPLD determines that PSU occurs that the alternatively possible implementation of power supply trouble can be,
CPLD monitors the power supply state of PSU the most in real time, to judge whether it power supply trouble occurs, and without
PSU sends fault signal.For example, it is possible to monitor whether the supply voltage of PSU is less than setting threshold value etc..
CPLD, after determining that power supply trouble occurs in PSU, needs powering mode by PSU power switching
Power for BBU, the realization of this switching need its within rank time nanosecond, to BBU, switch P,
Switch B sends and enables signal accordingly.Such as, first CPLD sends closing control instruction to switch P,
So that switch P is by performing this instruction to be off, thus reach to cut off from PSU through switch P
To being powered these power supply circuits of equipment.
Step 205: switch P receives the closing control instruction that CPLD sends, and by performing this closedown
Control instruction is to be off.
In detail, switch P can be by bidirectional blocking (two-way blocking switch) and controller
(controller) forms.Such as, the controller in switch P is receiving the closedown that CPLD sends
During control instruction, can be become by closure state to control bidirectional blocking by performing this instruction
For off-state.
Meanwhile, when needing hot_swap (hot plug) function in view of server, controller is permissible
There is softstart (soft start) function.
In one implementation, open control instruction if first sending to BBU, then send out to switch P
Send closing control to instruct, then there may be BBU and start power supply, but switch B disconnects, switch P connection
Situation, this situation can cause the electric current of BBU to pour in down a chimney to PSU.Therefore, in the present embodiment,
In order to avoid occurring that electric current pours in down a chimney phenomenon during powering to BBU from PSU power switching, opening
Before opening BBU, it is necessary first to close the switch P corresponding with PSU, therefore CPLD can be first to switch P
Transmission closing control instructs.
But, can be to complete in nanosecond rank owing to CPLD enables the transmission of signal, therefore may deposit
In signal delay in various degree.For this situation, switch P can be set as by bidirectional
The two-way blocking switch module of blocking and controller composition, can avoid the occurrence of above-mentioned electricity further
Stream pours in down a chimney phenomenon.
In the present embodiment, when needs switching powering mode, on the one hand, CPLD can be according to predetermined
Signal transmission order to send each enable signal, on the other hand, involved switch can be two-way
Blocking switch module.By this implementation, can be prevented effectively from powering mode handoff procedure and be caned
The electric current that can occur pours in down a chimney phenomenon.
Step 206: after sending closing control instruction to switch P, CPLD is in first time period
Send enable signal to BBU respectively, send to switch B and open control instruction.
In one implementation, CPLD to switch P send closing control instruction after, Ke Yitong
Time to BBU and switch B send enable signal accordingly.
Step 207: switch B receives the unlatching control instruction that CPLD sends, and by performing this unlatching
Control instruction is to be in connected state.
Similar with switch P, switch B is equally by bidirectional blocking and controller
Composition.
Additionally, switch B can also be by N mosfet (Metal-Oxide-Semiconductor Field-Effect
Transistor, Metal-Oxide Semiconductor field-effect transistor) and controller composition.Meanwhile, for
Realizing being switched fast of powering mode, the opening speed of mosfet wants fast equally, therefore can select threshold value
The mosfet that voltage is less, opening speed is fast.Same, may be selected that the controller of quickly response.
Step 208:BBU receives the enable signal that CPLD sends, and is in connection at switch B
During state, start the equipment of being powered is powered.
BBU, after receiving enable signal, opens the output of self electric current, and is at switch B
During connected state, can pass through from BBU through switching B to being powered these power supply circuits of equipment to being supplied
Electricity equipment is powered.
Additionally, in a kind of possible implementation, it is also possible to set up BBU Yu BMC (Baseboard
Management Controller, baseboard management controller) annexation.Wherein, BMC can be
BBU receives the enable signal that CPLD sends, i.e. BBU starts to be powered the equipment of being powered
Time, the power supply cruising time of monitoring BBU and dump energy.Owing to powering period at BBU, server
Load program is indefinite, thus can BMC monitor power supply cruising time and dump energy in any one
Individual when reaching respective settings threshold value, export warning reminding signal.Such as, the setting threshold powered cruising time
Value can be predetermined total the 20% of duration of powering, and the setting threshold value of dump energy can be the 20% of total electricity.
Step 209: when PSU monitors the elimination of described power supply trouble, opens the output of self electric current, and
Right signal is sent to CPLD.
Monitor with PSU and occur that the implementation of power supply trouble is similar, eliminate at power supply trouble, as prominent
So after power-off a period of time during normal power-up, PSU equally monitors the situation that power supply trouble eliminates.
Then, PSU mono-aspect can automatically turn on the output of self electric current, to be changed to connected state at switch P
Time, by switch P circuit, the equipment of being powered can be powered, on the other hand can send out to CPLD
Send right signal.
Step 210:CPLD receive PSU send right signal time, within the second time period to
Switch B sends closing control instruction.
Similar with CPLD reception fault signal, when it receives the right signal that PSU sends,
May determine that the power supply trouble of PSU eliminates.Accordingly, CPLD determines what PSU power supply trouble eliminated
Alternatively possible implementation can be, CPLD monitors the power supply state of PSU the most in real time, to judge
Whether its power supply trouble is eliminated, and sends right signal without PSU.
Same, when needing that BBU powering mode is switched to PSU powering mode, can first make switch
B disconnects, to be first turned off the supply line that the equipment of being powered is powered by BBU by switch B.
Step 211: switch B receives the closing control instruction that CPLD sends, and by performing this closedown
Control instruction is to be off.
Step 212: after sending closing control instruction to switch B, CPLD is within the second time period
Send disable signal to BBU respectively, send to switch P and open control instruction.
In one implementation, CPLD to switch B send closing control instruction after, Ke Yitong
Time to BBU and switch P send enable signal accordingly.
Step 213:BBU, when receiving the disable signal that CPLD sends, stops being powered equipment
Power supply.
BBU, when receiving disable signal, can be automatically stopped the output of self electric current, right to stop
The equipment of being powered is powered.It is apparent that when switching B and disconnecting, BBU powering mode terminates.
Step 214: switch P receives the unlatching control instruction that CPLD sends, and by performing this unlatching
Control instruction is to be in connected state.
Step 215: when switching P and processing connected state, PSU starts to be powered the equipment of being powered.
When switching P and being in connected state, PSU can be through switch P circuit, again to being powered equipment
It is powered, thus completes powering mode and supply power to, from BBU, the switching that PSU powers.
Step 216:PSU, while being powered the equipment of being powered, starts to charge BBU, with
And when BBU charging complete, terminate BBU is charged.
Due to the consumption of the existing distinct program of the electricity of storage in BBU powering phase, BBU, therefore
PSU powering phase, BBU can be charged by PSU, until BBU charges to full.This mode
Powering mode can be switched in real time, to ensure so that follow-up time PSU power supply trouble occurs again
Server normally works.
In the present embodiment, when there is power supply trouble in PSU, can quickly by powering mode by PSU
Power switching is that BBU powers, and when PSU power supply trouble eliminates, then by powering mode by BBU
Power switching returns PSU and powers, and charges to BBU full, in case the switching of follow-up powering mode is used,
Thus ensure that server can normally work, it is to avoid the loss of data that the server machine of delaying suddenly is caused occurs
Phenomenon.
