After the technical scheme of the embodiment of the present invention is described, the various non-limiting realities of detailed description below the application
Apply mode.
Referring first to Fig. 1, Fig. 1 is a kind of schematic flow sheet of method for managing power supply provided in an embodiment of the present invention, this hair
Bright embodiment may include herein below：
S101：When the default power supply signal for detecting PSU occurs abnormal, the instruction of data backup is sent, is switched simultaneously
BBU is powered, and is sent the instruction of fan and the power-off of default ancillary equipment.
PSU power good signals and AC fail are signally attached to CPLD in advance, in order to be monitored to PSU,
Timely notice system is backed up to operating data.It is any in power good signals and AC fail signals when monitoring
Exception occurs for one signal or two signals, then judges that current PSU breaks down, such as PSU short circuits, or PSU power supplies
Power-off etc..
In addition, Expander, the control signal of SAS controller power supplys can be connected into CPLD, when being easy to control progress
The control and economize on electricity control of sequence.
When detecting PSU abnormal electrical power supplies, during system (such as server, notebook computer lamp) is currently running, if performing
Dry business, then in order to avoid losing the data being currently running, can send the instruction of data backup by PM8054 to CPU, will
The data being currently running are stored, it is ensured that the security of data.When receiving, the power supply that CPLD sent by PM8054 is different
Data backup is carried out after regular signal, is written to above onboard SSD.
Because the electricity that BBU is stored is limited, power consumption when BBU powers can be reduced, extend BBU continued powers time and
The cycle of discharge and recharge.The power supply of the default ancillary equipment of system can be turned off when PSU breaks down, typically except CPU,
Internal memory, hard disk, can need other in system the device or device of power supply all to turn off, for example LCDs, USB interface,
PM8504, PM8717 etc..
But, for fan, because the operation of each device can produce heat in system, in order to by unnecessary disperses heat,
The operating temperature for maintaining internal system suitable, it is ensured that system and each device normally operation, it is necessary to radiated using fan,
When being powered using PSU, PM8054 writes corresponding value to reach control wind by iic bus toward register fixed in CPLD
The rotating speed of fan.Because there is fan certain rotating speed to be operated always when PSU is normal, when PSU just breaks down, fan due to
Inertia will not shut down immediately, in order to further reduce BBU use time, can close fan, allow it to utilize
Inertia remains in operation, but the operating of inertia has regular time, therefore, can be by the electricity of fan before fan is out of service
Open in source.
If it should be noted that when PSU exceptions occurs in (i.e. system is just started shooting) at the beginning, can be notified by IIC link
PM8054, forbids system to carry out data service storage, immediately closes system, can also prompt system keeper or user set
Standby maintenance.
S102：When detecting the BBU and starting power supply, the instruction of opening the fan is sent in preset time, and
The rotating speed of the fan is configured according to preset rotation speed value, the preset rotation speed value is supplied less than the fan in the PSU
Tachometer value when electric.
By test of many times and it has been observed that fan can maintain 2s or so operating using inertia, therefore can be in the PSU
Default power supply signal occur after exception two seconds, send the instruction of opening the fan.When BBU powers, if fan is still
Higher rotating speed is kept, the power consumption of whole system has not only been drawn high, and larger noise can be caused.If taking the timing of interruption one
Between after keep relatively low rotating speed again, not only take full advantage of the inertia of original fan, and reduce the work(of whole system
Consumption and noise.The rotating speed of fan can be controlled by PWM dutycycle.
Because when being powered using PSU, PM8054 is worth accordingly by iic bus toward register write-in fixed in CPLD
To reach the rotating speed of control fan, and when BBU powers, in order to extend power-on time, it will close PM8054, therefore it can not pass through
The rotating speed of PM8054 controlling fans.Therefore default tachometer value can be prestored, and when BBU is powered, this turn of fan use
Speed maintains operation.Preset rotation speed value can be the 50% of fan maximum (top) speed, certainly, or other values, meet in system
Temperature position maintain under suitable operational temperature conditions, it is the smaller the better.General, when PSU is powered, due to operation
Device is more, and the rotating speed of fan maintains maximum rotating speed.
In order to further extend BBU power-on time, it is ensured that system is in normal operating temperature, for turning for fan
The setting of fast value can also be：
Receive the rotation speed of the fan value of user's input；
The rotating speed of the fan is configured according to the rotation speed of the fan value.
User or those skilled in the art can be according to the real-time condition (numbers and system temperature of the device run in system
Degree), and ambient temperature at that time, the rotating speed of fan is adjusted in real time.The further stability and reliability for ensureing system,
Be conducive to extending BBU power-on time.
In technical scheme provided in an embodiment of the present invention, the power management to system is realized by CPLD, when PSU occurs
During failure, the data being currently running in system are backed up, and are switched to BBU in time and are powered, ancillary equipment is closed
Power supply and adjustment rotation speed of the fan, not only ensure that the security of data, also reduce the power consumption and noise of system, effectively prolong
BBU use time has been grown, has been conducive to the reliability and stability of lifting system.
In order to search the reason for PSU breaks down as soon as possible, and repaired in time, the application also provides another reality
Example is applied, referring to Fig. 2, can be applied to device or system that notebook computer, server etc. carry storage device, it may include：
S201：When the default power supply signal for detecting PSU occurs abnormal, the instruction of data backup is sent, is switched simultaneously
