A part of embodiment of the present invention, rather than whole embodiments, based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained on the premise of creative work is not made, belongs to the scope of protection of the invention.
As shown in figure 1, the embodiment of the invention provides a kind of server power supply PSU condition control methods, the method can be with
Comprise the following steps：
Step 101：Determine that the first band of PSU carries threshold value and the second band load threshold value.
Step 102：Determine that the first band carries the first output current threshold value of the threshold value correspondence PSU.
Step 103：Determine described second the second output current threshold value with the threshold value correspondence PSU is carried.
Step 104：Any current output current value with PSU is carried of detection, and step 105 and step 106 are performed respectively.
Step 105：When the current output current value is less than the first output current threshold value, any band of control
PSU is carried to close.
Step 106：When the current output current value is more than the second output current threshold value, control is any without load

In embodiments of the present invention, by determining that PSU first bands corresponding compared with high workload efficiency carry threshold value and the second band is carried
Threshold value, wherein, it is PSU lower limits corresponding compared with high workload efficiency that first band carries threshold value, and the second band load threshold value is PSU compared with high workload
The corresponding higher limit of efficiency, and threshold value and the second band load threshold value are carried according to first band, determine that the first of correspondence PSU is defeated respectively
Go out current threshold and the second output current threshold value, so, due to when workload increase or reduce when, band load PSU output
Electric current can change therewith, therefore, the current output current of PSU can be carried by real-time detection band, judge it whether less than first band
Threshold value is carried, if it is, being closed by controlling band to carry PSU, will be worked with compared with high workload efficiency with PSU levelling is carried；And judgement is
No second band that is more than carries threshold value, if it is, pass through control being opened without PSU is carried, will be aligned with compared with high workload efficiency with PSU is carried
Work such that it is able to make server power supply PSU be worked with efficiency higher.
In an embodiment of the invention, in order to carry threshold value obtains correspondence PSU first according to the first band for determining
Output current threshold value, and then for control PSU is turned on and off laying the foundation, the specific embodiment of the step 102 includes：
Wherein, I characterizes the first output current threshold value；P characterizes the rated power of the PSU；U characterizes the PSU's
Constant output voltage value；λ characterizes the first band and carries threshold value；
In order to obtain the second output current threshold value of correspondence PSU with load threshold value according to second for determining, and then it is control
PSU processed is turned on and off laying the foundation, and the specific embodiment of the step 103 includes：
Wherein, M characterizes the second output current threshold value；P characterizes the rated power of the PSU；U characterizes the PSU's
Constant output voltage value；S characterizes second band and carries threshold value.
The operating efficiency of PSU can similar be downward parabola with the relation with load threshold value, specifically can be described as with PSU
Increase with carrying, the operating efficiency of PSU first rises and declines afterwards, wherein, when it is 50% that band carries threshold value, the operating efficiency of PSU is most
Height, most energy-conservation, are optimal working conditions, it is contemplated that the working condition of reality, and to avoid one band of setting from carrying
Threshold value and PSU is in the situation opened, close so that, the optimal band that have selected PSU carries threshold interval,
Wherein, it refers to the optimal lower limit of correspondence PSU operating efficiencies that first band carries threshold value, and it refers to correspondence PSU work that the second band carries threshold value
The optimal higher limit of efficiency.And the setting of the two values is not unique, can be set according to user's request, but must be ensured
In interval included by the two values, the operating efficiency of PSU is optimal.
For example, first band carries threshold value λ=40%, the second band carries the rated power p=2500w of threshold value S=65%, PSU, permanent
Determine output voltage values u=12.5v, then by above-mentioned formula (1) calculate PSU the first output current threshold value I beThe second output electricity of PSU is calculated by above-mentioned formula (2)
Flowing threshold value M is
By determining the first output current threshold value and the second output current threshold value of PSU, in this manner it is possible to by real-time detection
To band carry the output current of PSU and compared respectively with it, and according to result of the comparison, control being turned on and off for PSU so that
To make PSU be laid the foundation with greater efficiency work.
In an embodiment of the invention, in order to avoid part PSU carry load works always, and residue PSU is always without load,
Further include：Timing detects that current each continuous band with PSU is carried carries the time；When being directed to each described continuous band load
Between, see if fall out default band and carry time threshold, if it is, controlling any one to be opened without PSU is carried；And control super
Go out a default band with time threshold is carried and carry PSU closings.
For example, having 10 PSU, band carries time threshold and is set to 15 days, detects weekly once, is detected at the 3rd week
When, detect altogether current 8 with carry PSU continuous bands carry the times be followed successively by { 15,20,8,16,17,10,9,19 } (unit：
My god), then can just be seen if fall out 15 days, wherein 20 days, 16 days, 17 days and 19 for each in this 8 values
It beyond 15 days so that can just control any one without carry PSU open, then control 20 days, 16 days, 17 days and
A corresponding band load PSU closing with carrying in PSU respectively in 19 days, e.g., optimal control mode is to close wherein continuous band to carry
Time band most long carries the PSU that PSU, i.e. continuous band carry 20 days, and remaining one then can also be controlled to be opened without PSU is carried, and
Close band most long in the remaining continuous band load time and carry PSU, i.e. the continuous band load PSU of 19 days, so as to complete this PSU wheels
Not.And in order to not influence power supply, can open without PSU is carried, after the extension regular hour, such as 10s treats this without load
After PSU stable power-supplyings, turn off band and carry PSU.
Control of having holidays by turns is carried out by PSU, the service life of each PSU can be made to reach balance, so as to extend power cabinet
The use time of body, makes whole electric power system more stablize, and reduces the maintenance cost to power supply.
In an embodiment of the invention, had holidays by turns the execution efficiency of control process to improve PSU, it is described be directed to it is every
One continuous band carries the time, before seeing if fall out default band load time threshold, further includes：Detect whether to deposit
At least one without PSU is carried, if it is, being directed to each described continuous band carries the time, see if fall out default
Band carries time threshold；Otherwise, then it is directed to each described continuous band and carries the time, the default band load time is not seen if fall out
Threshold value.
For example, having 10 PSU, band carries time threshold and is set to 15 days, detects weekly once, is detected at the 10th week
When, it is not detected by without load PSU, namely current is 0 without the number for carrying PSU, so as to can just save continuous to what is detected
Judgement with time threshold is carried, because even current have the PSU carried beyond 15 days continuous bands, also without dormancy without carrying PSU
Carry out replacement of having holidays by turns, and then this PSU controls of having holidays by turns terminate, and wait the adjustment of having holidays by turns of the 11st week.
When PSU has holidays by turns control, by detecting whether exist without PSU is carried, if it is present carrying out control of having holidays by turns accordingly
System, otherwise, terminates this and has holidays by turns, and then improves whole PSU and have holidays by turns the execution efficiency of process.
In an embodiment of the invention, it is 40% that the first band carries threshold value, and it is 65% that second band carries threshold value.
In an embodiment of the invention, the first output current threshold value is 80A, and the second output current threshold value is
130A。
Be below 40% by threshold value is carried with the first band of 5+5 PSU, PSU, it is as a example by 60%, to originally that the second band carries threshold value
A kind of server power supply PSU condition control methods that inventive embodiments are provided are described in detail, as shown in Fig. 2 the method can
To comprise the following steps：
Step 201：It is one week to pre-set the detection cycle that PSU has holidays by turns.
Wherein, detection cycle can be set according to user's request, but not too short, in order to avoid due to detection frequency too
Height, influences the normal work of server.In embodiments of the present invention, the detection cycle of setting is one week, and so, rack management is single
First RMC can be detected periodically weekly, so as to control each PSU carry load works in turn.
Step 202：It is 15 days to pre-set band and carry time threshold.
Step 203：It is 40% to determine that the first band of PSU carries threshold value, and it is 60% that the second band carries threshold value.
In embodiments of the present invention, [40%, 60%] is the optimal band load interval of PSU, that is to say, that when the band of PSU is carried
When value is in the interval, the operating efficiency of PSU is optimal.
Step 204：The the first output current threshold value I for determining 40% correspondence PSU is 80A.
In embodiments of the present invention, the constant output voltage value of PSU is 12.5v, and rated power is 2.5kw, such that it is able to
The maximum output current value of PSU is calculated for 2.5kw/12.5v=200A, then the first output current threshold value I/200A=40%,
So that it is determined that go out the first output current threshold value I=40% × 200A=80A of 40% correspondence PSU, analysis process herein namely
Formula (1), and the situation of current threshold is determined with load threshold value suitable for other.
Step 205：The the second output current threshold value M for determining 65% correspondence PSU is 130A.
From step 204, the second output current threshold value M/200A=80%, so that it is determined that going out the of 65% correspondence PSU
Two output current threshold value M=80% × 200A=130A, namely formula (2).
Step 206：Any current output current value with PSU is carried of detection is x.
Because the rated power of each PSU is identical, output voltage values are identical, therefore, in the output current of detection PSU
When, PSU (referring to that in a dormant state, output current value is 0A to PSU without PSU is carried) can be carried for any band and detected, that
The current output current value x for detecting has three kinds of situations：1st kind：80A≤x≤130A；2nd kind：X ＜ 80A；3rd kind：X ＞
130A.Wherein, for the 1st kind of situation, without being turned on or off in control PSU, because now the operating efficiency of PSU has been
Most preferably, but, with the change of workload, the comparing that remaining two kinds of situations occur is more.
Step 207：Whether x is judged less than 80A, if it is, performing step 208, otherwise, performs step 209.
Step 208：Any band of control carries PSU and closes, and performs step 206 and step 211.
When x ＜ 80A are judged, illustrate that current work load is less, but it is more for the PSU of share load, namely
PSU is more for band load, so as to cause the operating efficiency of current PSU not high, therefore, control any PSU to close, so that band carries PSU bands
Load value in [40%, 60%], to make the operating efficiency of PSU strictly corresponding with interval, that turn off it is any with load PSU it
Afterwards, output current that need to be again to now arbitrary band load PSU detect, if the value for detecting [80A, 130A] it
Between, then proceed detection, if that is also less than 80A, then any band of secondary control carries PSU and closes, until in the area
It is interior, it is necessary to explanation, be not in that the output current of band load PSU is more than from being sported less than 80A in real process
The situation of 130A, therefore, finally the output current value that band carries PSU can be always controlled in the interval range of [80A, 130A],
So as to improve the operating efficiency of PSU, energy resource consumption is reduced.
Step 209：Whether x is judged more than 130A, if it is, performing step 210, otherwise, performs step 206.
Step 210：Control is any to open without load PSU, and performs step 206 and step 211.
When x ＞ 130A are judged, illustrate that current work load is more, but it is less for the PSU of share load, namely
With carrying, PSU is less, so as to cause the operating efficiency of current PSU not high therefore controllable any without PSU unlatchings are carried, to share
Load.Principle in specific implementation process such as above-mentioned step 208 is identical, is not repeating herein, in a word can be by the output of PSU electricity
Flow valuve is controlled in the interval range of [80A, 130A], and then PSU is worked with operating efficiency higher, reduces energy resource consumption.
Step 211：Timing weekly detects that current each continuous band with PSU is carried carries time ti。
Wherein, from 1 to n (n≤10), when detecting weekly, the value of n may be different to i, and corresponding t1~tn
It is not quite similar, for example, when detecting within the 3rd week, n=6 illustrates that 6 bands are had during now test carries PSU work, and t1~t6Successively
It is { 17,19,18,12,16,16 } (unit:My god).
Step 212：Detect whether to exist at least one without PSU is carried, if it is, performing step 213, otherwise, terminate
Current process.
If in current detection, and in the absence of without PSU is carried, then with or without the PSU carried beyond 15 days continuous bands,
This PSU adjustment of having holidays by turns will terminate, and wait adjustment of having holidays by turns next time, if that is detected the presence of without load PSU, e.g.,
It is corresponding with above-mentioned steps 211, detect 4 and then continue this PSU and have holidays by turns adjustment without PSU is carried, so that the continuous band load time
PSU more long is closed, open under stand-by state without carrying PSU.
Step 213：For each ti, judge tiWhether exceed 15 days, if it is, performing step 214, otherwise, terminate
Current process.
It is corresponding with above-mentioned steps 211, wherein, there are 5 continuous bands to carry the time beyond 15 days.If that t1~t6According to
Secondary is { 9,9,8,4,8,7 } (unit:My god), then without departing from 15 days, so also terminate this PSU have holidays by turns adjustment, continue etc.
Treat to have holidays by turns next time.
Step 214：Control any one to be opened without load PSU, and control a band load PSU beyond 15 days to close.
It is directed to such as the judgement each time in step 213, i.e., 5 continuous bands carry the times beyond 15 days, can control
Make any one and opened without PSU is carried, and after this is without PSU stable power-supplyings are carried, close in this 5 any one or continuous band
The band of load time (19 days) most long carries PSU, and that has 4 without load PSU in embodiments of the present invention, currently, therefore, this next round
Not can adjust 4 bands and carry PSU, and remaining one then needs when adjustment of having holidays by turns next time.
