Main element symbol description
Embodiment
As shown in Figure 1, be the applied environment figure of baseboard management controller preferred embodiment of the present invention.Wherein, this baseboard management controller (BaseboardManagementController, BMC) 20 operates on mainboard 2, and this mainboard 2 also comprises chip 21, fan 22 and fan governor 23.
Described BMC20 is connected with chip 21 and fan governor 23.Specifically, this BMC20 is connected with fan governor 23 by communication stitch (such as, CommunicationPin), and this BMC20 is connected with chip 21 by the hot stitch of processor (such as, ProcessorHotPin).Described BMC20 detects fan by the current potential reading communication stitch and whether fan governor is working properly.When fan or fan governor work occur abnormal, described BMC drags down the frequency of operation of chip 21 by the hot stitch of processor, thus reduces the thermal value of chip 21.Described chip 21 may be, but not limited to, central processing unit (CentralProcessingUnit, CPU), graphic process unit (GraphicProcessingUnit, GPU), coprocessor and other chip.
Described fan 22 is arranged on chip 21 or around chip 21, and this fan 22 is for dispelling the heat to chip 21.Described fan governor 23, for monitoring fan 22, makes fan 22 rotate according to the requirement of fan governor 23.
As shown in Figure 2, be the process flow diagram of control method for fan preferred embodiment of the present invention.
Step S10, store in described BMC20 fan 22 and fan governor 23 normally work time communication stitch the parameter of potential change.The parameter of described potential change refers to when fan 22 and fan governor 23 normally work, the current potential of communication stitch every Preset Time noble potential (such as, value between 4 volts to 5 volts is noble potential) and electronegative potential (value such as, between 0 volt to 0.3 volt is electronegative potential) alternately change.Described Preset Time can be arranged according to user's request, and such as, in 1 second, noble potential and electronegative potential alternately change once.For example, as shown in Figure 3, when fan 22 and fan governor 23 normally work, current potential noble potential (5 volts) and electronegative potential (0 volt) alternately change in 1 second of communication stitch, 0 to 0.5 second noble potential, 0.5 second to 1 second electronegative potential.The parameter of described potential change can also associate with the rotating speed of described fan 22, such as, when fan 22 and fan governor 23 normally work, to 0.5+T stopwatch, 0+T shows that the rotating speed of fan 22 is 3000 revolutions per seconds second, to 1+T, 0.5+T represents that the rotating speed of fan 22 is 4000 revolutions per seconds second, wherein T indication cycle, such as, described in Fig. 3, cycle T is 1 second.
Fan 22 and fan governor 23 normally work time communication stitch current potential alternately change realized by fan governor 23, specifically, fan governor 23 is every the current potential of Preset Time change communication stitch.
Step S11, described BMC20 read the current potential of communication stitch at set intervals.Specifically, after mainboard 2 powers on, described BMC20 reads twice current potential within the cycle of potential change.Such as, described BMC20 is in 0.2 second first time reading potential, and described BMC20,0.7 second second time reading potential, after this read a current potential every 0.5 second.
Step S12, described BMC20 judge whether the current potential of the communication stitch of described reading meets the parameter of the potential change stored in described BMC20.Specifically, whether alternately described BMC20 judges the current potential change of the communication stitch read.
When the current potential of described reading does not meet the parameter of described potential change, and work as certain hour (such as, 10 seconds) in the current potential of communication stitch of described reading when being noble potential, this BMC20 judges that exception appears in described fan governor 23, this fan governor 23 cannot be monitored fan 22, and fan governor 23 cannot by the noble potential change electronegative potential of communication stitch.
When the current potential of described reading does not meet the parameter of described potential change, and when in certain hour (such as, 10 seconds), the current potential of the communication stitch of described reading is electronegative potential, this BMC20 judges that exception appears in described fan 22.Specifically, when fan 22 is abnormal, fan governor 23 will trigger an interruption, and this interruption will drag down the current potential of communication stitch, described BMC20 is by latch (Latch) the monitoring communications stitch on BMC20 and receive this interruption, and then the current potential of communication stitch learning fan governor 23 is electronegative potential, when this BMC20 at certain hour (such as, 10 seconds) in the current potential of communication stitch that reads when being all electronegative potential, this BMC20 judges that exception appears in described fan 2.
Step S13, when fan 22 or fan governor 23 occur abnormal, described BMC20 drags down the frequency of operation of chip 21 by the hot stitch of processor, thus reduce the thermal value of chip 21, avoid because exception appears in fan 22 or fan governor 23, cannot dispel the heat in time, cause that chip 21 temperature is too high to be damaged.
Step S14, described BMC20 generate a notes record, and send to system manager.Described record comprises the rise time, occurs abnormal reason, and occurs abnormal device name (such as, fan 22 or fan governor 23).
Above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to above preferred embodiment to invention has been detailed description, those of ordinary skill in the art should be appreciated that and can modify to technical scheme of the present invention or be equal to the spirit and scope of replacing and should not depart from technical solution of the present invention.
