Embodiment
Below in conjunction with accompanying drawing and preferred embodiments the present invention is described in further detail:
Please refer to Fig. 1, denoising device of the present invention is arranged in the container data center 1, is placed with some servers 2 in this container data center 1.See also Fig. 2, the preferred embodiments of this denoising device 3 comprises a baroceptor (Gas Pressure Sensor) 10, one rotation speed of the fan Adjustment System 12, a temperature sensor 15 and a timer 16.
This baroceptor 10 is arranged at the porch at this container data center 1.When the staff entered into container data center 1, the air pressure of porch promptly can change, thus make 10 outputs of this baroceptor corresponding control signal to this rotation speed of the fan Adjustment System 12 and timer 16.This timer 16 picks up counting when the control signal of receiving from baroceptor 10.In this execution mode, also available other of this baroceptor 10 can be sensed the discrepancy transducer replacement that the staff enters into 1 inside, container data center, like the infrared ray sensing apparatus.
This rotation speed of the fan Adjustment System 12 can be and is arranged at the inner Control Software System of a server 2, and it is used for when the control signal that receives from baroceptor 10, reducing the rotating speed of the radiator fan of the Servers-all 2 that is positioned at container data center 1.In this execution mode, this rotation speed of the fan Adjustment System 12 can be exported to the pulse width modulation of fan through change, and (pulse width modulation, PWM) duty of signal recently changes the rotating speed of fan.Wherein, the staff can set up on their own when receiving control signal, and this rotation speed of the fan Adjustment System 12 is set at original 80% or other percentage with the duty ratio of pwm signal.Can make so that when the staff enters into the container data center rotating speed of fan promptly reduces at once, thereby has reduced the noise at container data center.
For the assembly in the server 2, (Central Processing Unit, CPU), its temperature can rise along with the time because of the decline of rotation speed of the fan slowly, and reaches stable afterwards in a period of time (as two minutes) of rising like central processing unit.The temperature of supposing CPU when fan rotates at full speed is 70 degree; After duty ratio that rotation speed of the fan Adjustment System 12 will be exported to the pwm signal of fan is set at original 80%; The temperature of CPU will slowly rise and be stabilized in 74 degree; Though the temperature of CPU when it exceeds fan and rotates at full speed can't influence the steady operation of system in the short time (like half an hour).
This temperature sensor 15 is arranged at the inside of some servers 2, is used for the temperature of sensing server 2 inner assemblies (like CPU), and sends the temperature value that sensing obtains to this rotation speed of the fan Adjustment System 12.When the temperature value that senses surpassed a set point (like 76 degree), this rotation speed of the fan Adjustment System 12 promptly increased the rotating speed of fan gradually, such as the duty ratio of pwm signal was increased by 2% in per 10 seconds.This setting can be by staff's adjustment voluntarily as required.
In addition; When these timer 16 timing reach a setting-up time when (like half an hour); This timer 16 also transmits a control signal and gives this rotation speed of the fan Adjustment System 12, and this rotation speed of the fan Adjustment System 12 also increases the rotating speed of fan gradually, such as the duty ratio of pwm signal was increased by 2% in per 10 seconds.This sets also can be by staff's adjustment voluntarily as required.In this execution mode, this setting-up time is to be to decide with interior in half an hour according to the time that staff generally speaking enters into container data center 1 half an hour, certainly in other execution mode, but this setting-up time proper extension.And, can know that according to top description this timer 16 also can omit, promptly judge whether to need to increase the rotating speed of this fan by temperature sensor 15.
When the staff accomplishes when the debugging of server 2 or maintenance left this container data center, the air pressure of porch changes once more, thus make that this baroceptor 10 export correspondence once more control signal to this rotation speed of the fan Adjustment System 12 and timer 16.This timer 16 stops timing and zero clearing when the control signal of receiving once more from baroceptor 10.
This rotation speed of the fan Adjustment System 12 increases the rotating speed of fan gradually when the control signal that receives once more from baroceptor 10, such as the duty ratio of pwm signal was increased by 2% in per 10 seconds.This sets the adjustment voluntarily as required by the staff.
Whether above-mentioned container data center 1 sees through baroceptor 10 inductions has the staff to enter in the container data center 1; And utilize in the staff enters into container data center 1 time rotation speed of the fan Adjustment System 12 to reduce the rotating speed of fans; To reduce the noise in the container data center 1, for the staff provides comparatively comfortable operational environment.When the staff accomplishes debugging or maintenance when leaving this container data center 1, this rotation speed of the fan Adjustment System 12 promptly increases the rotating speed of fan gradually, can steady operations to guarantee server 2.In addition, the temperature in these temperature sensor 15 real-time sensing servers 2, when the temperature in the server 2 during above set point, this rotation speed of the fan Adjustment System 12 promptly increases the rotating speed of fan gradually, and is too high and influence its stability to avoid server 2 temperature.In addition, when the timing of this timer 16 reached setting-up time, this rotation speed of the fan Adjustment System 12 also can increase the rotating speed of fan gradually.
Please refer to Fig. 3 and Fig. 4, the preferred embodiments of noise-reduction method of the present invention may further comprise the steps:
Step S1: the air pressure of this 1 porch, air pressure sensor 10 sensing container data centers, and judge whether the air pressure of porch changes.Execution in step S2 then when the air pressure of porch changes.Repeating step S1 then when the air pressure of porch is constant.
Step S2: this timer 16 picks up counting.
Step S3: this rotation speed of the fan Adjustment System 12 reduces the rotating speed of the radiator fan of the Servers-all 2 that is positioned at container data center 1.In this execution mode, this rotation speed of the fan Adjustment System 12 can recently change the rotating speed of fan through the duty that the pwm signal of fan is exported in change, is adjusted into original 80% like the duty ratio with pwm signal.
Step S4: the temperature of these temperature sensor 15 sensing servers 2 inner assemblies, and send the temperature value that sensing obtains to this rotation speed of the fan Adjustment System 12.
Step S5: judge whether the temperature value that sensing obtains surpasses set point.If surpass then execution in step S6 of set point.If be no more than then execution in step S7 of set point.
Step S6: this rotation speed of the fan Adjustment System 12 increases the rotating speed of fan gradually, such as the duty ratio of pwm signal was increased by 2% in per 10 seconds.This setting can be by staff's adjustment voluntarily as required.
Step S7: judge whether timing time reaches setting-up time.If reach setting-up time, then execution in step S8.If do not reach setting-up time, then execution in step S10.
Step S8: this timer 16 stops timing and zero clearing.
Step S9: this rotation speed of the fan Adjustment System 12 increases the rotating speed of fan gradually, such as the duty ratio of pwm signal was increased by 2% in per 10 seconds.This setting can be by staff's adjustment voluntarily as required.
Step S10: the air pressure of this 1 porch, air pressure sensor 10 sensing container data centers, and judge whether the air pressure of porch changes once more.If change then execution in step S10 once more, otherwise execution in step S4.
Step S11: this rotation speed of the fan Adjustment System 12 increases the rotating speed of fan gradually, such as the duty ratio of pwm signal was increased by 2% in per 10 seconds.This sets the adjustment voluntarily as required by the staff.
