The invention further provides a fan control method. By the fan control system and method, the speed of the corresponding fans is regulated according to the power consumption information of the devices, so that the devices are cooled effectively.
Description
Technical field
The present invention relates to a kind of fan control system and method.
Background technique
Along with the lifting of the performance of electronic component, the heat that electronic component produces when operation also increases thereupon.In order effectively to discharge the heat producing when electronic component moves, common way is to use a fan, by fan, unnecessary heat is taken away.When the heat of electronic component generation increases, the rotating speed of fan also increases thereupon.Yet, the rotating speed of existing fan is that the temperature while moving according to electronic component is adjusted, and between electronic component work and the heat of its generation, have certain time interval, thereby may cause the rotating speed of fan not adjust in time making electronic component cannot discharge timely the situation that occurs operation irregularity because of heat.
Summary of the invention
In view of above content, be necessary to provide a kind of fan control system and the method that can adjust in time rotation speed of the fan.
A fan control system, is applied to as some equipment coolings, and this fan control system comprises:
Some voltage regulators, are used to these equipment that operating voltage is provided, also for exporting the power consumption information of corresponding device;
Some fans, are used to these equipment to dispel the heat; And
One tracks down chip, for receiving the power consumption information of these voltage regulators output, and the power consumption information of the equipment obtaining according to reception control correspond to this equipment cooling fan rotating speed.
A control method for fan, comprises the steps:
Obtain per unit power consumption information; And
According to the power consumption information output one acquiring, control signal to fan that relevant device is dispelled the heat to regulate rotation speed of the fan.
Fan control system of the present invention and method regulate the rotating speed of corresponding fan according to the power consumption information of equipment, thereby effectively these equipment are dispelled the heat.
Accompanying drawing explanation
Fig. 1 is the skeleton diagram of the better embodiment of fan control system of the present invention.
Fig. 2 is the flow chart of the better embodiment of control method for fan of the present invention.
Primary component symbol description
Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Please refer to Fig. 1, fan control system of the present invention is for dispelling the heat to some equipment 20, to guarantee the normal work of these equipment 20.The better embodiment of this fan control system comprises some fans 10, somely provides the VRD(Voltage Regulator Down of operating voltage, voltage regulator for these equipment 20) 30, one according to the power consumption information of these VRD 30 outputs control these fans 10 rotating speed track down chip 40 and a storage 50.
In present embodiment, the quantity of these VRD 30 is identical with the quantity of these equipment 20, and each VRD30 provides operating voltage for an equipment 20.In other embodiments, a VRD 30 also can be a plurality of equipment 20 operating voltage is provided.Each VRD 30 tracks down chip 40 by I2C bus or PMBus and this and communicates.In present embodiment, the power consumption information of each VRD 30 outputs comprises and is connected in the current value that the equipment 20 of this VRD 30 consumes.In other embodiments, this power consumption information also can be the size that is connected in the power that the equipment 20 of this VRD 30 consumes.
These fans 10 are for dispelling the heat to these equipment 20.Each equipment 20 can be dispelled the heat by one or more fans 10.As the first equipment can be dispelled the heat by one first fan, the second equipment is dispelled the heat by one second fan.Certainly, this first equipment also can be dispelled the heat by first and second fan simultaneously.
This storage 50 has been stored the maximum (top) speed of each fan 10.
This tracks down chip 40 for control the rotating speed that corresponds to the fan 10 that this equipment 20 dispels the heat according to the power consumption information of each VRD 30 outputs.While being 1A as the power consumption information of the first corresponding equipment when VRD 30 output, this is tracked down 40 of chips and controls these first fans with 60% speed operation of its maximum (top) speed, to meet the radiating requirements of this first equipment.When the power consumption information of the first corresponding equipment of VRD 30 output is 1B (wherein 1B is greater than 1A), this is tracked down 40 of chips and controls these first fans with 80% speed operation of its maximum (top) speed, to meet the radiating requirements of this first equipment.
In other embodiments, this tracks down chip 40 also for judging whether these fans 10 exist a fan 10 to be greater than a Preset Time to be greater than the time of a setting speed operation.When existing a fan 10 to be greater than this Preset Time to be greater than the time of this setting speed operation, the heat that the equipment 20 that represents to be dispelled the heat by this fan 10 produces is very large.In present embodiment, this setting speed is this fan with the operation of its maximum speed, and certainly, in other mode of executions, this setting speed also can be set as surpassing 80% speed operation of maximum (top) speed.Now, this tracks down the rotating speed that 40 increases of chip close on other fans of this fan, to meet the radiating requirements of this equipment.As when this first fan is greater than this Preset Time to be greater than the time of this setting speed operation, this tracks down 40 rotating speeds that increase this second fan of chip, with this, meets the heat radiation requirement of this first equipment.
Please refer to Fig. 2, the better embodiment of control method for fan of the present invention comprises the steps:
Step S1, this is tracked down chip 40 and obtains per unit power consumption information.
Step S2, this is tracked down chip 40 and controls signal to according to the power consumption information output one acquiring the fan that this equipment is dispelled the heat.
Step S3, judges whether to exist a fan to be greater than this Preset Time with the time that is greater than setting speed operation, when the time that exists a fan to continue high speed operation is greater than this Preset Time, and execution step S4; Otherwise this flow process finishes.
Step S4, increase closes on the rotating speed of other fans of this fan.
Said fans control system and method regulate the rotating speed of corresponding fan 10 according to the power consumption information of equipment 20, thereby effectively these equipment 20 are dispelled the heat.
