Specific implementation mode
Core of the invention is to provide a kind of fan detection method, and this method can be applied to baseboard management controller
(Baseboard Management Controller, BMC), is detected the fan in server.Specifically, by obtaining
The signal identification of control signal is taken, amount rotating speed is obtained；Tach signal is obtained from the rotating speed line of fan, and then is obtained corresponding practical
Rotating speed.Then, amount rotating speed and actual speed are compared, determines fan performance index, completes the detection to fan.Certainly, in order to
Simple detection, can also be compared according only to actual speed and preset rotary speed threshold value, determine fan whether aging or failure.
That is, the fan of aging or failure can be found in time, to carry out timely replacement operation, the normal operation of server is ensured.
Another core of the present invention is to provide a kind of fan detection device, equipment and computer readable storage devices, has
Above-mentioned advantageous effect, details are not described herein.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.Obviously, described embodiments are only a part of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, shall fall within the protection scope of the present invention.
Referring to FIG. 1, Fig. 1 is a kind of flow chart of fan detection method in the embodiment of the present invention, this method includes following
Step：
S101, when being detected to fan, obtain the corresponding signal identification of control signal of current control fan.
Wherein, the duty ratio of signal identification signal in order to control, control signal are pwm control signal.
When being detected to fan, the corresponding signal identification of control signal of current control fan can be obtained.Wherein
It can be pwm control signal to control signal, and signal identification is specifically as follows the duty ratio of control signal.Specifically, can pass through
The control signal of fan control line is obtained, then control signal is parsed, determines its corresponding duty ratio.Of the invention real
It applies in example, the time for carrying out fan detection can be carried out when server is more idle, periodically can also periodically be detected,
It can also be detected in real time.For carrying out the time of fan detection, comparison of the embodiment of the present invention does not limit.
Correspondingly, in one embodiment of the invention, can also be to execute following steps before executing S101：When
When reaching default detection trigger condition, preset control signal is inputted to fan.That is, when reaching preset detection trigger condition
When, input preset control signal to fan.Wherein, it can be the time cycle to preset detection trigger condition, can also be to receive
To a detection instruction or the triggering of other events.It, can when executing step S101 when it is preset signals to control signal
Directly acquire the corresponding preset signals mark of preset signals.
S102, fan corresponding actual speed under control of the control signal is obtained.
Fan corresponding actual speed under control of the control signal can be obtained by the rotating speed line of fan.

Including a control line and a rotating speed line.That is, in the present embodiment, the control letter exported on the rotating speed line of fan can be obtained
Number control under tach signal, then tach signal is parsed, corresponding actual speed can be obtained.
S103, it reads and presets look-up table, determine rated speed corresponding with signal identification.
After obtaining signal identification, preset look-up table can be read, it may be determined that volume corresponding with the signal identification
Spend rotating speed.Wherein, amount rotating speed can be the theoretical rotational speed of fan under ideal conditions.Because control signal duty ratio with work as
Preceding server health is related, for example, general 2:00 AM server is more idle, rotation speed of the fan also compares bottom, but double
11 ought cat server 2:00 AM everyday, rotation speed of the fan be bound to it is very high because server is in high loaded process.That is, pre-setting
The corresponding table of one operating status and amount rotating speed also can determine the corresponding volume of control signal by the busy extent of current system
Spend rotating speed.
S104, actual speed and rated speed are compared, determines and export the performance index of fan.
After obtaining actual speed and amount rotating speed, the two is compared, it may be determined that go out the virtual index of fan, and
Performance index is exported.Wherein, performance index can be indicated in the form of percentage, can also be with different performance rates
It is indicated.For the specific manifestation form of performance index, the embodiment of the present invention does not limit.
In one embodiment of the invention, step S104 can be specially：Calculate the hundred of actual speed and amount rotating speed
Divide ratio, percentage is determined as to the performance index of fan, and output performance index.That is, directly by actual speed and amount rotating speed
Percentage be determined as performance index.Currently, in other embodiments of the invention, also other way of contrast, specifically
Way of contrast is referred to common way of contrast, and details are not described herein.
In one embodiment of the invention, it is compared by actual speed and rated speed, determine and exports fan
Performance index after, can also include：
When performance index is less than predetermined threshold value, the prompt messages of fan are replaced in output.
It that is, after output performance index, can also judge whether the virtual index is less than predetermined threshold value, work as performance index
Less than predetermined threshold value, the prompt messages of fan are replaced in output, so that maintenance personnel replaces fan in time, just with server
Often operation.
It should be noted that executing sequence about above-mentioned steps, step is had to carry out before executing step S103
S101 needs the operation for executing step S101, S102 and S103 before executing step S104.Step S102 need to only executed
It is completed before step S104.The execution sequence of above-mentioned steps meet above-mentioned execution sequence limitation can be realized it is of the invention real
Apply the purpose of example.
