Speed and alarm threshold value judge whether the operating status of fan propeller is normal, generate alarm signal if abnormal, and control and its phase
Alarm module even generates warning message.
It should be noted that in the present embodiment, there are one alarm modules for a blower module connection.And the present invention other
Can be that there are one alarm modules for multiple blower module connections, that is to say, that the quantity of alarm module is less than or equal in embodiment
The quantity of blower module.
Baseboard management controller 100 is used to receive what blower module 200A or blower module 200B was sent by second interface
Alarm signal.
It should be noted that need to be each fan in baseboard management controller to realize alarm design in the prior art
Module carries light-guiding pillar, and this mode needs baseboard management controller determining corresponding fan propeller based on acquisition second signal
When running abnormal, determine that the blower module for generating alarm signal, alarm response are slow.
And in the present embodiment, alarm module is transplanted in blower module, and fan is determined in monitor speed controller
The alarm module alarm that automatic trigger is coupled when rotor is abnormal so that alarm response is fast, while also saving mainboard report

The alarm signal of generation is sent to by device processed by the fan interface of blower module and the second interface of baseboard management controller
Baseboard management controller.
Wherein, second interface is specifically as follows remote alarm interface.
Optionally, baseboard management controller is determined for generating the wind of alarm signal after receiving alarm signal
Fan module.When electronic equipment only includes a blower module, the blower module for generating alarm signal can be directly determined.Work as electricity
When sub- equipment includes at least two blower modules, the blower module for generating alarm signal can be to the same of baseboard management controller
One second interface sends alarm signal.So, baseboard management controller, which is used to receive by same second interface, generates alarm signal
Number blower module send alarm signal.In this case, baseboard management controller obtains corresponding fan by the 4th interface
The second signal of module determines blower module corresponding with alarm signal based on second signal.
Wherein, each blower module corresponds to the 4th interface, i.e., the fan interface of different blower modules corresponds to base
The 4th different interface on board management controller, the wind that baseboard management controller passes through the 4th corresponding blower module of interface
Fan interface is communicated, and obtains second signal from the monitor speed controller of blower module, second signal is converted to fan
The actual speed of the fan propeller of module determines blower module corresponding with alarm signal based on actual speed.
Specifically, actual speed is compared with preset rotating speed of target, rotating speed deviation is determined, by rotating speed deviation and report
Alert threshold value is compared, and determines that the blower module that rotating speed deviation is more than alarm threshold value is blower module corresponding with alarm signal.Its
In, the blower module that rotating speed deviation is more than alarm threshold value is that reception and rotating speed deviation are more than the corresponding second signal of alarm threshold value
Blower module corresponding to 4th interface.
Optionally, alarm signal can be sent to system end by baseboard management controller after receiving alarm signal, with by
System end makes this corresponding response.
In still another embodiment of the process, monitor speed controller is also connected with the alarm module of electronic equipment, this method
Further include：When determining that the operating status of the fan propeller is abnormal, controls coupled alarm module and generate alarm signal
Breath.
Each embodiment is described by the way of progressive in this specification, the highlights of each of the examples are with other
The difference of embodiment, just to refer each other for identical similar portion between each embodiment.For method disclosed in embodiment
For, since it is corresponding with device disclosed in embodiment, so description is fairly simple, related place is said referring to device part
