[specific embodiment]
It is clear in order to be more clear the purpose of the present invention, technical solution and advantageous effects, below in conjunction with attached drawing and
Specific embodiment, the present invention will be described in further detail.It should be understood that specific reality described in this specification
Mode is applied just for the sake of explaining the present invention, is not intended to limit the present invention.
Fig. 1 is please referred to, the present invention also provides a kind of rotation speed of the fan Automatic adjustment methods, comprising the following steps:
Step S01 is established with multiple cores plate and is communicated to connect, and periodically receives the current operation letter of each core board
Breath, current operational information includes the current rotating speed of the temperature of the corresponding CPU of each core board, the service condition of RAM and fan.
Wherein, the period for receiving the current operational information of each core board can be according to user demand sets itself, such as period
It is set as 30S, the current operating situation for receiving a core board is acquired every 30S.It further, can be according to different IPs core
Control area or control function, different core boards is arranged the collection period of different operation informations, such as frequently transporting
Row loads the first collection period of biggish core board setting, for being arranged without frequently running or loading lesser core board
Second collection period, the time of time of the first collection period less than the second collection period.
Step S02 predicts each core board corresponding CPU lower period according to the current operational information of each core board
Interior heat radiation power and the temperature change for judging a CPU relatively upper period, calculate the corresponding fan of an each core board lower period
Interior speed revolution value.
Please with reference to Fig. 2, by taking a core board as an example, RAM is the storage unit on core board, i.e. CPU is directly therewith
The component for communicating and using its storing data, for storing the data and program of (in the executing) that is being currently used.Periodically
It receives and the service condition information for understanding RAM can be appreciated that whether a cycle server starts or close some application
Software, service information.Specifically, the application software of server starting is more, then RAM use is more, and the calculation amount of CPU is got over
Greatly, heat production is more, temperature rise is faster；Conversely, the application software of server starting is fewer, RAM use is fewer, and the calculation amount of CPU is got over
Small, heat production less, temperature rise it is slower.
Namely the service condition of the RAM of each core board can directly react the calculation amount of CPU in the core board, according to
The calculation amount of CPU can predict the heat production function in a CPU lower period in the core board in turn in core board described in current period
Rate；The revolving speed of fan and the heat radiation power of fan be directly proportional, needs to guarantee that the temperature of CPU in core board is stablized so that fan
The heat radiation power in next period is consistent with the heat production power in a CPU lower period, and then can be according to the heat production function in a CPU lower period
Rate predicts the heat radiation power in next period of fan.
Inevitably, it is limited by chassis space, the extraneous factors such as the wind direction of fan influence, the practical heat dissipation of fan
Inevitably there are errors with the heat production power of the CPU of prediction for power.The temperature change in the CPU of an each core board relatively upper period
It can play the role of certain auxiliary corrective to the revolving speed of next period fan is predicted, and corresponding with each core board of prediction
Heat radiation power in a CPU lower period controls the revolving speed of next period fan together.
Step S03 adjusts core board according to the speed revolution value in the corresponding fan of an each core board lower period for calculating
Corresponding rotation speed of the fan.
In one embodiment, when the service condition of RAM is unchanged, i.e. server operation application software, service is constant
When, the heat production power of CPU is stable；Fan is operated simultaneously with corresponding constant rotational speed, and the heat radiation power of fan can be with
The heat production power of CPU keeps a dynamic balance state.
When the service condition of RAM in a cycle changes, i.e., server start or close some application software,
When service, CPU heat production power changes.Specifically, when server starts some application software, service, the use of RAM
Become more, the power of CPU heat production becomes larger, and will increase if adjusting the temperature of the revolving speed CPU of fan not in time；Work as server closing
When some application software, service, the use of RAM tails off, and CPU heat production power becomes smaller, and fan can only be expired with lesser revolving speed
The radiating requirements of sufficient CPU, if it will cause the wastes of electric energy for the revolving speed of adjusting fan not in time.
The heat production power that CPU in next period is predicted according to the situation of change that current period RAM is used, to adjust in advance
The revolving speed for saving corresponding fan keeps the heat radiation power of corresponding fan consistent with the heat production power of CPU.Specifically, if current period
The use of RAM becomes more, predicts that the heat production power of CPU in next period will become larger, needs to increase the revolving speed of fan, so that wind
The heat radiation power of fan is close with the heat production power of CPU, so that the temperature of CPU is in reasonable traffic coverage；If current week
The use of phase RAM tails off, and when predicting the heat production power of the CPU in next period will reduce, can reduce the revolving speed of fan, make
The heat radiation power for obtaining fan is close with the heat production power of CPU, reduces the power consumption of fan；As CPU in prediction next period
Heat production power is constant, and rotation speed of the fan remains unchanged.
Further, the heat production power correlation for the situation of change and CPU that RAM is used, for the heat dissipation for making fan
The heat production power of power and CPU keep dynamic equilibrium, therefore the situation of change used by RAM adjusts the revolving speed of fan in advance.Example
Such as, the 25-35% of RAM is by use, can be by within the scope of the rotational speed regulation to 2500-2800r/min in a fan lower period, i.e.,
The heat production power of the heat radiation power and CPU that can make fan keeps dynamic equilibrium；The 35-45% of RAM is by use, can be by fan
Within the scope of the rotational speed regulation to 2800-3200r/min in next period, the heat radiation power of fan and the heat production power of CPU can be made
Dynamic equilibrium is kept, the temperature of CPU will not increase；Likewise, the 15-25% of RAM is by use, can be by a fan lower period
Rotational speed regulation to 1500-2000r/min within the scope of, can make fan heat radiation power and CPU heat production power keep dynamic
Balance.
Although the situation of change used according to RAM adjusts the revolving speed of fan in advance, the heat production power and wind of CPU may make
The heat radiation power dynamic equilibrium of fan.But it is influenced by external environment, the heat production power of CPU and the heat radiation power consistency of fan
Inevitably there are error, need to carry out auxiliary amendment to the revolving speed of fan by other means.In the present embodiment, fan is turned
Speed carries out auxiliary amendment and is realized by the temperature change in a CPU relatively upper period.
Specifically, the heat radiation power of fan is less than the heat production of CPU if the constant temperature in a CPU relatively upper period increases
Power can increase the revolving speed of fan；If the constant temperature in a CPU relatively upper period reduces, the heat radiation power of fan is greater than
The heat production power of CPU can reduce the revolving speed of fan to reduce the power consumption of fan；If the temperature change in a CPU relatively upper period is not
Obviously, then the heat production power of the heat radiation power of fan and CPU are in dynamic balance state, and rotation speed of the fan remains unchanged.
In one embodiment, current operational information further includes the periodic frequency for receiving CPU, it is generally the case that
CPU guarantee in the range of 30 degrees Celsius of temperature rise be usually it is stable, temperature rise is more than that 30 degrees Celsius of CPU can make down conversion process, into
And influence the performance of server.Frequency by receiving CPU judges CPU's compared with the frequency range that CPU is worked normally
Whether temperature is in reasonable traffic coverage.Enter the uncertainty of frequency reducing critical-temperature and the heat dissipation function of fan due to CPU
The heat production power of rate and CPU cannot be completely the same, and the temperature of CPU is likely to be breached the critical-temperature of frequency reducing at any time, so when receiving
CPU frequency be lower than CPU work normally frequency range (i.e. when CPU enters frequency reducing state), immediately increase fan turn
Speed improves the heat radiation power of fan；When the frequency of received CPU is in the frequency range that CPU is worked normally, rotation speed of the fan is protected
It holds constant.By periodically receiving the frequency of CPU, and compared with the frequency range that CPU is worked normally, it is ensured that when CPU long
Between run within a reasonable temperature range, auxiliary protection is played to the monitoring temperature of CPU.
Rotation speed of the fan Automatic adjustment method provided by the invention, on the one hand by periodically receiving each core board
Current operational information predicts the heat radiation power in the corresponding CPU of an each core board lower period and judges that CPU is one week relatively upper
The temperature change of phase calculates the speed revolution value in the corresponding fan of an each core board lower period, so that the heat radiation power of fan
It is consistent with the heat production power of corresponding CPU, and then make the temperature of CPU in reasonable traffic coverage, on the other hand pass through the period
Property reception CPU frequency, compared with the frequency range of normal CPU, it is ensured that CPU is constantly within the scope of normal temperature
Operation.Rotation speed of the fan Automatic adjustment method provided by the invention, so that the temperature change section of CPU is small, stable and fan
It is low in energy consumption.And the current operational information by periodically detecting core board predict the cpu temperature in next period become
Change, to predict that the revolving speed for calculating next period internal fan adjusts rotation speed of the fan in advance, to guarantee that fan is not necessarily to turn with fixed
While speed operating, cool down without improving bigger revolving speed again after temperature rises, improves cooling efficiency and saving
The energy.
