For above and other objects of the present invention, feature, advantage and embodiment can be become apparent, being described in detail as follows of appended accompanying drawing:
Fig. 1 illustrates existing fan control deadbeat intention.
Fig. 2 illustrates the server system synoptic diagram according to one embodiment of the invention.
Fig. 3 illustrates the process flow diagram of the fan control speed method in server system shown in Figure 2.
Embodiment
Below will and describe clear explaination spirit of the present invention in detail with accompanying drawing, any those of ordinary skill in the art is after understanding preferred embodiment of the present invention, when can be by the disclosed technology of the present invention, change and modification, and do not break away from spirit of the present invention and scope.
Please in conjunction with reference Fig. 2 and Fig. 3, Fig. 2 illustrates the server system synoptic diagram according to one embodiment of the invention, and Fig. 3 illustrates the process flow diagram of the fan control speed method in server system shown in Figure 2.As shown in Figure 2, be distributed with a plurality of temperature-sensitive stickers 102 on the mainboard of server system 200 inside, a plurality of fans 100 are arranged at and are used in the server system 200 heat is discharged.At first, the mainboard of server system is divided into a plurality of zones, each zone has at least one temperature-sensitive sticker 102, and each zone is all to there being one or more fans 100.Be four zones shown in Fig. 2, but not as limit.Then, be each region division one mirror image sensor, and be the off-set value of a correspondence of each temperature-sensitive sticker 102 setting in each zone that the value of reading of mirror image sensor is actual value of reading and its corresponding off-set value sum of a temperature-sensitive sticker 102.Secondly, be at least one fan speed control table of each region allocation, fan speed control table stores the corresponding relation of rotation speed of the fan and the mirror image sensor value of reading, and fan speed control table is stored in the baseboard management controller of server system 200 usually.Then, obtain actual value of reading of a temperature-sensitive sticker 102, and obtain the value of reading of its corresponding mirror image sensor in conjunction with its off-set value.At last, adjust corresponding rotation speed of the fan with the value of reading of this mirror image sensor with reference to corresponding fan speed control table, thus Control Server internal system temperature.
In addition, each zone comprises first kind temperature-sensitive sticker and Equations of The Second Kind temperature-sensitive sticker at least, and first kind temperature-sensitive sticker is different with the precision of Equations of The Second Kind temperature-sensitive sticker, coupling is that each region allocation has first fan speed control table corresponding with first kind temperature-sensitive sticker and second fan speed control table corresponding with the Equations of The Second Kind temperature-sensitive sticker therewith.Specifically, the precision of first kind temperature-sensitive sticker is 0.5 degree centigrade, and the precision of Equations of The Second Kind temperature-sensitive sticker is 1 degree centigrade, and therefore, the first fan speed control table stepping is 0.5 degree centigrade, and the second fan speed control table stepping is 1 degree centigrade.
That is to say, in the present embodiment, each zone is all to having first fan speed control table and second fan speed control table, wherein, the sensing precision is that 0.5 degree centigrade first kind temperature-sensitive sticker is the first fan speed control table of 0.5 degree centigrade corresponding to stepping in each zone, and the sensing precision is that 1 degree centigrade Equations of The Second Kind temperature-sensitive sticker is the second fan speed control table of 1 degree centigrade corresponding to stepping.So, corresponding two the control speed tables in each zone, the demand that whole server system only needs eight control speed tables just can cover all temperature-sensitive stickers 102 is controlled speed.
Because the actual value of reading that will show to the user temperature-sensitive sticker 102, so this actual value of reading can not change, so need to carry out mapping with fan speed control table in conjunction with off-set value by the mirror image sensor.Specifically, please refer to Fig. 3, adopt the mirror image sensor to control speed, need to after initialization, set an off-set value (step 300) for each temperature-sensitive sticker, then, obtain actual value of reading of temperature-sensitive sticker, and with this actual value of reading and its off-set value sum value of reading (step 302) as the mirror image sensor, then, with the value of reading of mirror image sensor and corresponding fan speed control table contrast, therefrom obtain the rotation speed of the fan corresponding with the value of reading of mirror image sensor (304), last, fan is adjusted to the temperature that this rotating speed comes the regulation server system.
Wherein, after actual value of reading of a plurality of temperature-sensitive stickers 102 in getting access to a zone, obtain a plurality of values of reading of mirror image sensor in conjunction with the off-set value of each temperature-sensitive sticker 102, adjust rotation speed of the fan with the maximal value in a plurality of values of reading of mirror image sensor with reference to fan speed control table.
Easily know by above embodiment, use the advantage of fan control speed method provided by the invention to be, utilize mirror image sensor and off-set value corresponding with fan speed control table, thereby in the situation that does not have hardware to change, utilize limited fan speed control table corresponding with a plurality of temperature-sensitive stickers, realize accurately control rotation speed of the fan, improve the radiating efficiency of system, and avoided the waste of the energy, reduced unnecessary noise.
Although the present invention discloses as above with embodiment; so it is not to limit the present invention; any those of ordinary skill in the art; without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention is as the criterion when looking accompanying the claim person of defining.
