Site preparation description.
Referring to Fig. 1, the embodiment of the present application provides a kind of service life method for early warning of equipment fan, and this method can wrap
Include following steps:
S101, select a fan as target fan from the fan group of the equipment.
For equipment, the multiple fans of deployment radiate generally in the form of fan group, to reach its radiating requirements,
The equipment can be the network equipment of such as router, interchanger, be also possible to server, PC etc..Wherein, fan group
In each fan can be provided with a number, for position a fan.
When equipment selects fan as target fan from fan group, can be selected according to preset sequence, example
Such as, include 12 fans in fan group, be respectively labeled as 1-12, can be selected according to the sequence of number from small to large
It selects.First using the fan of number 1 as target fan.
Following test operation is executed to the target fan:
S102, the target fan is closed.
The power supply for cutting off the target fan selected, makes the target fan stop working.
S103, the power parameter for obtaining the target fan, and the target fan is carried out based on the power parameter
Electricity.
If the revolving speed of S104, the target fan is less than preset rotation speed, the service life of the target fan is carried out
Early warning.
If the revolving speed of the target fan is greater than preset rotation speed, then it is assumed that the target fan is normal, woth no need to carry out early warning,
The target fan is restored to normal operating conditions.And return to S101 and reselect a fan as target fan, into
Row test operation.
According to the number of the target fan, the power parameter of the target fan is obtained, the power parameter is for being again started up
The fan receives detraction to determine whether the service life of the fan receives, and the mode of judgement is started based on this power parameter
Afterwards, when detecting its starting the case where revolving speed.During fan work, since the factors such as abrasion will cause asking for revolving speed decline
Topic, under rated voltage when steady operation, the reduction of revolving speed is unobvious, is difficult to be judged.But in starting fan, due to not
Influence of the case where formation stable state, abrasion to revolving speed is easier to highlight, and therefore, selection is first closed fan and started again to be sentenced
It is disconnected.
Control form of the power parameter based on fan stored by fan is different, which, which can be, is based on
Equipment obtained value when being tested early period, and be stored in equipment and used for equipment in advance.Optionally, it is carried out by voltage value
In the case where speed regulation, which can be lowest starting voltage, for example, the voltage rating of fan can be 12V, this is minimum
Starting voltage can be 5V；Alternatively, the power parameter can be minimum in the case where being adjusted the speed by digital pulse signal
Pulse-width modulation PWM duty ratio, for example, the specified PWM duty cycle of fan is 80%, which is 30%.
If the revolving speed of the target fan fails to reach preset revolving speed, it may be considered that the target fan has occurred one
The abrasion for determining degree, works on, and may cause the target fan and stalls suddenly.Due to that can include many fans in fan group,
All there are problems that abrasion, if left, it works on, the case where stopping working respectively there are several fans, such one
Come, be unable to satisfy the radiating requirements of equipment entirety, and replaces fan one by one and be also required to a period of time, in this period, deposit
The apparatus overheat the problems such as, equipment reliability of operation is reduced.
When the target rotation speed of the fan started under determining power parameter is less than preset rotation speed, based on corresponding to the target fan
Number 1 export early warning, prompt staff, fan service life corresponding to the number 1 is substantially reduced.
After the completion of the test operation, a fan is reselected as target fan, and execute test operation, until
The test of the fan group is completed, that is, restarts the step of executing S101-S104.
After the completion of being directed to the test of a fan, selects a fan as target fan again, repeat above-mentioned
Test operation, until all fans are all completed.At this point, the case where staff can be according to equipment early warning, in advance into
Row replacement, stops working brought equipment fault so as to avoid occurring a large amount of fans in the short time.
When in order to avoid carrying out test operation to the fan in fan group, the heat dissipation of equipment is influenced.Further, to institute
After the service life progress early warning for stating target fan, further includes:
The voltage rating for making the full revolving speed operation of the target fan is obtained, is supplied with the voltage rating to the target fan
Electricity；Alternatively,
The pwm signal comprising making the PWM duty cycle of the full revolving speed operation of the target fan is obtained, the pwm signal is based on
Control the revolving speed of the target fan.
Because during testing fan group, inevitably needing to close fan, also, be based on power supply
When parameter is tested, revolving speed is centainly lower than the revolving speed of fan normal work.So, it is tested for a fan
Afterwards, the problem of needing to restore the normal work of the fan, declining to avoid the heat dissipation effect of this period between early warning and replacement.
Certainly, the normal fan of preset rotation speed is greater than for revolving speed, it is also desirable to execute the step, fan is made to restore to work normally.
At this point, equipment (can be the feelings of minimum operating voltage relative to power parameter according to the voltage rating got
Condition) or PWM duty cycle the case where (relative to power parameter being minimum PWM duty cycle) of full speed running be that target fan carries out
Power supply, so that the target fan restores normal operating conditions after a test.
For the S104 in above-mentioned test operation, it is possible to further use the mode of grading forewarning system to refine early warning
Form keeps equipment more accurate for the early warning of fan, comprising:
If the revolving speed of the target fan is zero, first order early warning is carried out to the target fan；
If the revolving speed of the target fan is greater than zero and is less than preset rotation speed, it is pre- to carry out the second level to the target fan
Alert, the rank of the second level early warning is lower than the rank of the first order early warning.
During test operation, when detecting that revolving speed is when starting according to power parameter to target fan
It is zero, then can be confirmed that target fan abrasion has been difficult to work on, carry out first order early warning, directly informing staff,
It needs to replace fan as early as possible.At this point it is possible to carry out the first mark, at regular intervals, example to the fan in first order early warning
Such as, 1 hour, an early warning is carried out with regard to the corresponding number of one time first mark of output, staff's carelessness is avoided to forget to replace.
When detect target fan is started according to power parameter when, revolving speed be greater than zero but be less than preset rotation speed when,
It may be considered that the target fan can still work a period of time, and non-critical, replacement is not had to temporarily.At this point it is possible to carry out
Second level early warning, the rank of the second level early warning are lower than the rank of first order early warning.
It is possible to further indicate to the fan label second of second level early warning, equipment can store the second mark and wind
Fan the corresponding relationship of number.For fan group all fan tests operation, be carried out according to certain period, then,
After the completion of this test operation, the corresponding relationship of equipment storage the second mark and fan number.Since these fans have gone out
Show a degree of abrasion, the stage not up to needed replacing, but first order early warning is likely to be breached after a period of time of reruning
Degree, therefore, when test operation starts next time, preferential test is by the fan of the second flag tag, to promote test
With the effect of early warning.
