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 applied to records center to regulate the rotating speed of some fans 80.The better embodiment of this fan control system comprises some the first mainboards 70, some the second mainboards 90, some temperature transducers 50 and FCB(fan control board, fan control panel) 60.
These first mainboards 70 all are connected with this FCB 60, the corresponding fan 80 of each first mainboard 70 is so that heat radiation, one BMC(Baseboard Management Control is set on each first mainboard 70, baseboard management controller) 77, the temperature parameter of this this first mainboard 70 of BMC 77 Real Time Monitorings.
These second mainboards 90 all are connected with this FCB 60, and the corresponding fan 80 of each second mainboard 90 is not so that heat radiation all arranges BMC 77 on these second mainboards 90.
Each temperature transducer 50 is by IPMB(Intelligent Platform Management Bus, Intelligent Platform Management Bus) connect this FCB 60.These some temperature transducer 50 scattering devices with the ambient temperature of this records center of Real-time Obtaining, for example, arrange this temperature transducer 50 at the cabinet angle of the server cabinet of records center near these first mainboards 70 and these the second mainboards 90.
This FCB 60 is connected with these some fans 80, and the IPMB instruction that these FCB 60 timed sending are used for obtaining device identity code has BMC to respond to each first mainboard 70 and each second mainboard 90 to differentiate on which mainboard.When this FCB 60 recognizes BMC 77 on this first mainboard 70 response is arranged, this FCB 60 namely sends and is used for obtaining the IPMB instruction of inductor parameter to the first mainboard 70 that response is arranged, to obtain the mainboard temperature parameter of each BMC 77, then regulate the rotating speed of the fan 80 corresponding with each the first mainboard 70 according to the mainboard temperature parameter that has obtained.When this FCB 60 is unidentified when having to this second mainboard 90 BMC 77 to respond, this FCB 60 namely reads the temperature parameter of each temperature transducer 50, to regulate the rotating speed of the fan 80 corresponding with each the second mainboard 90 according to the temperature parameter that has obtained.
