Fig. 1 is please referred to, Fig. 1 is a kind of step flow chart of fan wind speed control method provided herein, is applied to
Processor between controller and fan, comprising:
Step 1: the pwm signal sent to fan o controller；
Step 2: obtaining the TACH signal of fan feedback, the current wind speed of fan is obtained according to TACH signal；
Firstly the need of being illustrated, server system usually can all utilize BMC or CPLD (Complex
Programmable Logic Device, Complex Programmable Logic Devices) carry out the Current Temperatures of reading service device system, then
Pwm signal is issued to fan further in accordance with Current Temperatures, to control the revolving speed of fan, while BMC or CPLD can also monitor wind in real time
The TACH signal sent is fanned, to confirm that fan current rotating speed is normal, it is to be understood that TACH signal is by exporting inside fan
A square-wave signal, the revolving speed of the frequency representative fan of the signal.
Specifically, the application has been placed in processor between controller and fan referring to shown in Fig. 2, controller is single defeated
Pwm signal is exported to processor, then by processor to fan out, meanwhile, processor is in the TACH signal for receiving fan feedback
Afterwards, TACH signal is analyzed, obtains the current wind speed of fan.
Step 3: judge whether current wind speed is in target zone, if so, 4 are entered step, if it is not, 5 are entered step,
In, target zone is corresponding with pwm signal；
Step 4: TACH signal being then switched to Duty cycle and feeds back to controller；
Step 5: then revise signal is sent to fan, so that the current wind speed of fan is in preset range.
Specifically, including the target zone that fan needs wind speed to be achieved in pwm signal, if the current wind that fan returns
Speed is not in target zone, and processor sends revise signal to fan, so that the current wind speed of fan is in target zone, such as
The current wind speed of fruit reach target zone then by TACH signal be converted to Duty cycle (duty ratio) then by pwm signal line it is anti-
It is fed to controller, using the scheme of the application, controller does not need to send pwm signal always, can determine by signal switching
Determining controller is that output pwm signal or reception TACH signal feedback, controller are only needed through single bilateral position foot signal just
It can achieve control fan speed and obtain the purpose of feedback wind speed, the optimization of the design of current server system is provided
Basis.

Specifically, may be had an impact to the transmission of signal in view of there are other devices in server system, be into
One step improves the reliability of the application, avoids error, when the current wind speed got is unsatisfactory for target zone, when being spaced one section
Between, then a TACH signal is reacquired, if according to the still discontented foot-eye model of current wind speed that the TACH signal newly obtained determines
It encloses, then sends revise signal to fan.Wherein, preset time determines that the application is it is not limited here according to actual requirement of engineering.
Embodiment as one preferred, while sending revise signal to fan, which is also wrapped
It includes:
Record the information for the fan that current wind speed is not in target zone.
Specifically, handled for the ease of the subsequent maintenance to fan, the application be also recorded can not by with the PWM that receives
The information of the fan of the corresponding revolving speed operation of signal, maintenance and replacement so as to maintenance personnel to fan further improve this
The reliability and safety of application.
In conclusion Design of power saving scheme is optimized by the automatic amendment wind speed of one kind provided herein, it can be effective
Judge the function of server fan, BMC controller can single sending pwm signal give frequency chip processor, then pass through frequency
Rate chip processor is transmitted further to fan, and frequency chip processor is receiving TACH signal, after frequency processing switching relatively, such as
Fruit comparison result is the pwm signal for meeting sending, then TACH signal is switched to Duty cycle and feeds back to BMC processor, if
Expected wind speed is not met after comparison, then self-recision is carried out by frequency chip, and BMC processor is only needed by single double
Logical position foot signal can achieve the purpose that control fan speed and obtain feedback wind speed, this designs current server system
There is sizable help.
