As shown in Fig. 2, the steady prosecutor method of fan provided herein is specifically to apply connecting with hardware monitoring chip
In control device, the output end of the control device in two control mainboards is connect by line with logic chip with fan.With BMC
Difference, the control device are specially the not power down device that shuts down, that is, after the main board system for storing equipment shuts down power down, the control
Device is still charged and can be worked normally, and therefore, during system closedown power down, which is always to be in stable operation shape
State, it thus can realize the stability contorting to fan.
Wherein, described control device concretely CPLD or FPGA.
Specifically, CPLD (Complex Programmable Logic Device, Complex Programmable Logic Devices) be
The device come out from PAL and GAL device development is a kind of user according to respective the need and voluntarily set of digits of constitutive logic function
At circuit, have that flexible in programming, integrated level are high, design and develop that the period is short, the scope of application is wide, developing instrument is advanced, price is public
The features such as change.
FPGA (Field-Programmable Gate Array, field programmable gate array) based on concurrent operation, with
Hardware description language is realized, is the product further developed on the basis of the programming devices such as PAL, GAL, CPLD.It is

Certainly, those skilled in the art can also be using other shutdown not power down devices as control described in the application
Device, the application are not limited thereto.
Referring to Fig. 3, a kind of fan steady prosecutor method of the dual control storage equipment provided by the present application during power down of shut down is applied
In the control device in the first control mainboard, this method is mainly comprised the steps that
S1: the motherboard power supply status signal and the drive of the first fan that the hardware monitoring chip in the first control mainboard is sent are received
Dynamic signal, the first fan driving signal are generated by hardware monitoring chip according to the fan speed-regulating signal that BMC is sent.
Wherein, the first described control mainboard is not some refered in particular in dual control storage two control mainboards of equipment, only
For the control mainboard where control device to be distinguished with another control mainboard.Equipment two controls are stored for dual control
For any one of device processed, where control mainboard be the first described control mainboard, and another controller
Control mainboard where part is the second control mainboard.
It, can be with as shown in Fig. 2, the hardware monitoring chip of control device provided herein and dual control storage equipment is connect
Receive motherboard power supply status signal and the first fan driving signal that hardware monitoring chip is sent.The first described fan drives letter
Number be specifically from hardware monitoring chip after BMC connected to it has sent fan speed-regulating signal to hardware monitoring chip, root
It is generated according to fan speed-regulating signal.It is as previously mentioned, I2C bus communication is generally used between BMC and hardware monitoring chip.
Generally, what the driving of fan utilized is PWM wave speed regulating control principle, the first fan of hardware monitoring chip output
Driving signal is a kind of PWM wave signal.Fan running speed: duty ratio can be changed in duty ratio size by adjusting PWM wave
Higher, the running speed of fan is faster；Duty ratio is smaller, and the running speed of fan is smaller.When duty ratio is 100%, fan
By full-speed operation.Generally, the revolving speed of the fan of full-speed operation may be up to 20000r/min, and noise may be up to 90dB.Certainly, no
The concrete condition for storing equipment and fan with model can slightly have difference.
It is easily understood that the motherboard power supply status signal and first that the hardware monitoring chip in the first control mainboard is sent
Fan driving signal is from the first control mainboard, and correspondingly, another control mainboard (installs situation in place
Under) i.e. motherboard power supply status signal and the first fan driving signal can be also generated in the second control mainboard.
Two control mainboards output the second fan driving signal warp and logical device carry out line and processing after export to
Fan drives end.In Digital Logical Circuits, only high level and high level line just export high level with after, participate in line and appoint
Signal of anticipating can all export low level when being low level.Therefore, the biggish driving signal of PWM duty cycle and PWM duty cycle compared with
After small driving signal warp and logical process, output is still the lesser driving signal of PWM duty cycle, i.e. PWM duty cycle
Lesser driving signal plays the role of master control.As a result, generally, the lesser driving of PWM duty cycle can be exported by main control mainboard
Signal, and by exporting the biggish driving signal of PWM duty cycle from control mainboard.
S2: judge whether the first control mainboard shuts down power down；If so, into S3.
It, can be according to mainboard electricity after the control device in the first control mainboard receives motherboard power supply status signal
Source status signal judges whether the first control mainboard of dual control storage equipment shuts down power down.
S3: whether the second control mainboard of detection shuts down power down；If it is not, then entering S4.
The power down if the first control mainboard is shut down, BMC will also shut down power down in the present embodiment at this time just will not benefit
The first fan driving signal for being generated under the BMC control action of the first control mainboard and driving fan.Similarly, for double
Another control mainboard i.e. the second control mainboard of control storage equipment, also needs to judge its power down of whether shutting down, so as to clear
Whether the BMC of the second control mainboard will also shut down power down.
S4: intercepting the first fan driving signal, generate and export the second fan driving signal of overall height level to line with patrol
Device is collected, to control fan running by the BMC of the second control mainboard.
The power down if the second control mainboard is not shut down, the BMC of the second control mainboard is in stable operation shape at this time
State, therefore, in the present embodiment, fan can be controlled by the BMC of the second control mainboard.First control master as a result,
Second fan driving signal of the exportable overall height level of the control device of plate is come from by the control device output of the second control mainboard
First fan driving signal of hardware monitoring chip, line with export later to fan still for the second control mainboard output first
Fan driving signal, that is, fan running is regulated and controled by the BMC of the second control mainboard.
The motherboard power supply status signal and that the application is sent by the hardware monitoring chip received in the first control mainboard
One fan driving signal, the first fan driving signal are generated by hardware monitoring chip according to the fan speed-regulating signal that BMC is sent；Sentence
Whether disconnected first control mainboard shuts down power down；The power down if so, whether the second control mainboard of detection shuts down；If the second control mainboard
It does not shut down power down, then intercepts the first fan driving signal, generate and export the second fan driving signal of overall height level to line
With logical device, so as to by the BMC of the second control mainboard control fan running.As it can be seen that the application is directed to dual control storage equipment
The control mainboard of shutdown power down replaces BMC to supervise the control to rotation speed of the fan, avoids using the control device of shutdown not power down
The unstability that fan control is caused because of BMC shutdown power down, has both ensured the proper heat reduction of storage equipment, has also avoided fan shakiness
Noise jamming when running surely, improves user experience.
Equipment is stored during power down of shutting down to dual control provided herein below by another specific embodiment
The steady prosecutor method of fan is further elaborated, and relative to a upper embodiment, the present embodiment has made further technical solution
Bright and optimization.Referring to Fig. 2, which includes:
S41: motherboard power supply status signal and the first fan that the hardware monitoring chip in the first control mainboard is sent are received
Driving signal, the first fan driving signal are generated by hardware monitoring chip according to the fan speed-regulating signal that BMC is sent.
S42: judge whether the first control mainboard shuts down power down；If so, into S43；If it is not, then entering S48.
S43: whether the second control mainboard of detection shuts down power down；If it is not, then entering S44；If so, into S45.
S44: intercepting the first fan driving signal, generate and export the second fan driving signal of overall height level to line with patrol
Device is collected, to control fan running by the BMC of the second control mainboard.
S45: judge whether the first control mainboard is default master control borad；If so, into S46；If it is not, then entering S47.
The power down if the second control mainboard is similarly shut down illustrates that the BMC of the second control mainboard and the first control mainboard is equal
It is unstable, then the control device in two control mainboards is needed to supervise the operating of fan.Specifically, as previously mentioned, two controls
There are master-slaves between mainboard processed, are used to export the PWM wave driving signal of overall height level from control plate, and master control borad is accounted for for exporting
Empty relatively low PWM drive signal.Therefore, need to determine whether the first control mainboard is default master control borad at this time.
S46: intercepting the first fan driving signal, generates the second fan driving signal that PWM duty cycle is default value, and
Output is operated to line and logical device to control fan with preset rotation speed.
If the first control mainboard is default master control borad, the control device of the first control mainboard can export and preset rotation speed
Second fan driving signal of corresponding duty ratio.Certainly, the second control mainboard is default from control plate, then the second control at this time
The control device of mainboard can then export the second fan driving signal of overall height level.Fan is input to later by line as a result,
Driving signal be still by the first control mainboard export driving signal, thus by the first control mainboard control device control wind
Fan is operated according to preset rotation speed.
Wherein, as a preferred embodiment, default value 20%, corresponding preset rotation speed can both meet centainly at this time
Radiating requirements, and not will lead to larger power consumption, while also avoiding high noisy when fan runs at high speed.It requires supplementation with
It is, since the power consumption of dual control storage equipment is higher, even if still being needed after dual control storage equipment completes shutdown power down
Fan is wanted to radiate with certain speed operating, control device can drive fan to operate with preset rotation speed always as a result,.
It should also be noted that, control device preferably uses closed-loop control to the control of rotation speed of the fan, it can real-time sampling
The actual speed of fan, compared with carrying out making difference with preset rotation speed by actual speed, by feedback control by the output of fan
Rotational speed regulation is preset rotation speed.
S47: intercepting the first fan driving signal, generate and export the second fan driving signal of overall height level to line with patrol
Device is collected, to control fan running by the control device of the second control mainboard.
Specifically, if the first control mainboard is not default master control borad, the control device output of the first control mainboard at this time
Second fan driving signal of overall height level.Meanwhile second control mainboard be default master control borad, the then control of the second control mainboard
The exportable duty ratio of device processed is the second fan driving signal of default value.Pass through line as a result, and is exported later to fan
For the driving signal of the second control mainboard output, that is, control fan running by the control device of the second control mainboard at this time.
S48: the first fan driving signal is exported to line and logical device, to be controlled by the BMC of the first control mainboard
Fan running.
Specifically, in the present embodiment, when the first control mainboard is in normal operating conditions there is no shutdown power down,
BMC is also stable operation, thus can then be controlled as a result, as being regulated and controled in the prior art by revolving speed of the BMC to fan
The first fan driving signal that device can send hardware monitoring chip is forwarded to fan, according to the fan speed-regulating instruction pair of BMC
Fan is regulated and controled.
