The operation principle of the present invention is as follows.
Electrical equipment heat (H)=thermal power (P) * times (t)/4.2
Fan cooling amount (H)=specific heat (C) * mass (m) the * temperature difference (△ T)
Quality (m)=air quantity (CFM) * density (ρ) the * times (t)
Air quantity (CFM)=1.76P/ △ T
Air inlet air mass flow=air inlet cross-sectional area * air inlet wind speed
Air quantity(Q)With rotating speed(n)Relation be directly proportional: Q1/Q2=n1/n2.
It can extrapolate:Q1/n1=Q2/n2=k Q=kn=1.76p/△t .Then n=k*p/ △ t can be extrapolated.Wind
Fan rotating speed is directly proportional to thermal power, is inversely proportional with the temperature difference.I.e. in the case where power and the temperature difference are certain, the heat that server is produced
Amount, and air quantity needed for distributing these heats is certain, the minimum speed required for fan is also certain in theory.
In the case of normal in air channel, the required airflow to meet, rotation speed of the fan can float in an a small range.But if
Air channel occurs in that abnormal conditions, to keep this air quantity, inevitably results in the change of rotation speed of the fan.Separately below to two kinds of air channels
Abnormal conditions are illustrated.
Air inlet air mass flow=air inlet cross-sectional area * air inlet wind speed.When the dust cover dust of air inlet is excessive,
Cause air inlet cross-sectional area to reduce, then need bigger air inlet wind speed.
In the case of wind scooper exception, fan is identical in the air quantity that same rotational speed is produced, but because wind scooper is led
The air channel of cause is abnormal, is changed under normal circumstances by the wind direction and wind velocity of radiating element, only partly passed through.Reach scattered
Thermal effect, rotation speed of the fan certainly will need to improve.
Beneficial effects of the present invention:The present invention can be monitored to air channel, and can in time be sent when air channel is abnormal
Warning, increases server reliability of operation.After warning information is received, the air channel of server is checked in time, energy
It is enough effectively to solve the heat dissipation problem that air channel is triggered extremely.
Brief description of the drawings
Fig. 1 is the DFD of embodiment processing method.
Embodiment
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Embodiment 1
20 degree of environment temperature, the CPU intelligent speed-regulatings of server are maintained at normal working temperature 70, and the heat power consumption of server is kept
100w is constant.In this case, if in the case of normal in air channel, rotation speed of the fan only needs to 30%(pwm 77)Rotating speed just
Radiating condition can be met.Higher it can guarantee that in the event of rotation speed of the fan 40% (pwm 102) or that just cpu temperature is maintained just
70 degree of normal temperature.Then think that air channel occurs in that exception, it is necessary to be alerted.
Embodiment 2
First, the server in normal air channel is sampled, sets up the corresponding table of heat power consumption, the temperature difference, rotation speed of the fan.
Wherein heat power consumption can in real time be obtained from heat generating components CPU, and the temperature difference is CPU parts and the difference of air intake vent temperature
Value.Rotation speed of the fan is to meet the current steady rotating speed under radiating condition.
During sampling, it should cover the working range of server as far as possible.For heat power consumption, CPU maximum heat is referred to
Power consumption TDP, sampling will at least cover the scope of (0.5*TDP -- TDP).It can be given using the method for running pressure test instrument
CPU pressurizes, to produce different real time power consumptions.
The normal working temperature scope of server is covered for the temperature difference, such as(10-40 degree);Also to cover CPU just
Normal operating temperature range, such as((Tjmax-40)-- Tjmax degree), SPEC concrete condition tool of the said temperature scope with CPU
Body is analyzed.In the case of environment temperature is too low,(Less than 10 degree), can be without sampling because of the big good heat dissipation effect of the temperature difference.In sampling
When, air conditioner refrigerating, wind-heat machine or temperature control aging computer room can be used, to take accurate data.The change of cpu temperature,
It is that the method pressurizeed by CPU is realized.Using 20 degree of environment temperature, heat generating components cpu temperature be 70 degree as example, then the temperature difference is
70-20=50 degree.
Simultaneously to reduce memory data output, sampling density can be controlled, such as power consumption carries out samples storage, temperature per poor 10w
Degree progress samples storage per poor 2 degree.By example of TDP180W, it is necessary to (180-90)/10+1=10 power consumption point.With environment temperature
(10-40 degree)Cpu temperature Tjmax88 degree(48-88 degree)For example, temperature range(88-10,48-40)(78,8), it is necessary to sample
(78-8)/ 2+1=36.Above-mentioned temperature range in some boundses may sampling less than can specifically be divided with concrete condition
Analysis.The sampling data table needed altogether needs the record data of 10*36=360.For the heat power consumption in sampling and temperature difference identical
Data, can carry out average value to rotation speed of the fan according to strategy or variance is handled.
The sampling instances table of table 1
Heat power consumption | The temperature difference | Rotation speed of the fan(pwm) |
80w | 48 | 145 |
80w | 46 | 176 |
2nd, the abnormal fault-tolerant detection in air channel
According to corresponding table and calculation formula, theoretic rotation speed of the fan under current environment is calculated, with actual rotation speed of the fan
Compare.If actual rotation speed of the fan exceeds threshold value 10%, then it is assumed that air channel is abnormal, the threshold value can adjust during operation.Detect wind
Road is abnormal, then marks once.Abnormal marking above, is performed once for every 10 seconds, to prevent wrong report, above-mentioned abnormal marking 5 minutes
Inside occur more than 15 times, then trigger air channel abnormality alarming.The multiple number of attempt and interval for preventing wrong report can be changed.
The computational methods to theoretical rotation speed of the fan are described below.If《Power consumption, the temperature difference, rotation speed of the fan》In table,
There are the power consumption matched with current environment, the temperature difference, then directly use the rotation speed of the fan in table as theoretical rotational speed.
Power consumption, the temperature difference if there is no matching.The method of linear approximation can be used to be handled.As above-mentioned table one is adopted
, can be with simple computation heat power consumption 80w, in the case of 47 degree of the temperature difference in sample example.Rotation speed of the fan is y.Then (y-145)/(176-
145)=(47-48)/(46-48), draws y=156.
Or rotation speed of the fan estimation equation can be used to be handled.A kind of numerical value of table is substituted into formula, rotation speed of the fan=normal
Measure the k* heat power consumptions/temperature difference+constant a.145=k*80/48+a,176=k*80/46+a.After the value for calculating k, a, substitution formula y=
k*80/47+a=155.It is substantially the same with the method for above-mentioned linear approximation.
3rd, after triggering alarm interface display and alarm is sent
In the SDR of server B MC systems, increase air channel abnormal index sensor.Air channel abnormal index, is a rotation speed of the fan
Deviation value.The computational methods of the value are:Actual speed/theoretical rotational speed.Threshold value bound 1.2,0.8 can be set in the exponential quantity.When
Alarm is triggered when going beyond the scope.The threshold range can modify according to actual conditions.
The sensor is shown on BMC web-based management interface.When the sensor readings exceedes threshold value, SEL is recorded, is touched
Transmit messages police, in the way of mail or SNMP, sends a warning message.
Increase a LED light on server panel, if detecting air channel exception, LED light is lighted.
As shown in figure 1, being the process chart of the inventive method.Sampling flow, generation heat power consumption, the temperature difference, rotation speed of the fan
Corresponding table.Testing process generates a sensor readings according to corresponding table and the real time power consumption temperature difference data of server.Web
Flow for displaying, sensor readings is shown.Alarm processing, then according to the threshold value set in SDR, triggering log recording SEL,
And daily record alarm is sent(Pass through email or snmp).
Although above-mentioned the embodiment of the present invention is described with reference to accompanying drawing, not to present invention protection model
