Step 30, when main control unit restores normal, the specified services disk Stop message interaction, and administration authority is given back
Main control unit is continued to carry out information exchange with each service board by the main control unit, is obtained the temperature of each service board and then is adjusted fan
Revolving speed.
It is temperature controlled simultaneously that interim master control progress is served as in the specified services disk, and also whether real-time monitoring main control unit is extensive
Multiple normal, when main control unit restores normal, the correspondence with foreign country of main control unit restores, and main control unit can be to the information of the specified services disk
Interaction make response, at this time the specified services disk judge main control unit restore normally, then the specified services disk no longer with other
Each service board carries out information exchange, and administration authority is given back main control unit, and interim primary role terminates.The main control unit is again
The information exchange between each service board is initiated, obtains the observed temperature of each service board, and fan is adjusted according to maximum temperature
Revolving speed, to realize temperature control.
In said fans control method provided by the invention, when main control unit works normally, temperature in GANTRY is managed by main control unit,
When main control unit exception, rotation speed of the fan is adjusted according to temperature by specified services disk adapter tube fan management, when main control unit restores normal
The administration authority of fan is returned again.It, can be according to each service board temperature when main control unit is normal or abnormal by this control method
The real-time adjusting rotation speed of the fan of degree, the drawback that fan directly turns at full speed when efficiently avoiding main control unit exception or fan is uncontrolled,
So that rotation speed of the fan in system had not only been met the temperature requirements of each single-deck in rack, but ensured system worked well, it is energy saving, subtract
Few noise extends fan service life.
In embodiments of the present invention, the control method for fan is that the temperature of closed loop controls, as shown in figure 5, main control unit is just
Often when work, operated according to process shown in Fig. 3；When main control unit exception, each service board judges itself according to interacting for main control unit
It whether is the specified services disk in specified slot position, if operated according to Fig. 4 process, in specified slot position for non-designated
The service board of slot position waits and carries out information exchange with the specified services disk；When main control unit restores normal, specified services disk will be managed
Reason power returns main control unit, and continuation is operated according to process shown in Fig. 3.
In conjunction with the embodiment of the present invention, there is also a kind of preferred implementations, in the step 20, when the specified industry
Be engaged in disk adapter tube main control unit administration authority and after obtaining the temperature of each service board, the specified services disk will be in other each service boards
The service board for meeting the second preset condition is determined as the second specified services disk；Wherein, described before the main control unit restores normal
Whether specified services disk real-time detection own temperature reaches preset threshold, when the temperature of the specified services disk reaches preset threshold
When, the administration authority of the specified services disk is taken over by the second specified services disk.This is allowed for, the specified services disk
A large amount of heat can be distributed during serving as interim master control, own temperature is caused to increase, when temperature increases to a certain extent
When, the specified services disk is just no longer appropriate for continuing to serve as interim master control, need at this time optionally suitable service board to take over
State the administration authority of specified services disk.Meet the second specified services disk of the second preset condition specifically: removing the specified industry
Be engaged in other each service boards other than disk, the observed temperature of the second specified services disk is minimum or observed temperature with it is corresponding
Default dangerous temperature between difference it is maximum.Wherein, the preset threshold can be the default danger in the specified services disk
It is arranged between the 70%-90% of dangerous temperature.
In conjunction with the embodiment of the present invention, there is also a kind of preferred implementation, multiple fan groups are equipped in the fan disk,
The then position distribution situation according to each service board and each fan group in rack carries out region division, Mei Gequ to rack in advance
In domain include a fan group and at least one service board, at least one described service board by the fan group in corresponding region into
Trip temperature control.Assuming that there is 16 service boards in rack, corresponding slot number is respectively Slot1-Slot16, includes 4 in fan disk
A fan group, and situation of arranging has 4 industry in each region as shown in fig. 6, rack can be then divided into totally 4 regions A, B, C, D
Business disk, 1 fan group.According to Fig. 6, when adjusting rotation speed of the fan, each region can be adjusted separately according to preparatory ready-portioned region
The rotation speed of the fan of internal fan group: according to the temperature of each service board in each region, rotation speed of the fan needed for determining each region, in turn
It drives the fan group in each region to export corresponding revolving speed, realizes that the temperature of each area traffic disk is adjusted.Wherein, in the finger
In the case where the administration authority for determining service board adapter tube main control unit, the specified services disk is adjusted respectively according to preparatory ready-portioned region
When the rotation speed of the fan of whole each region internal fan group, it is contemplated that the specified services disk workload is big, and heat dissipation capacity is big, therefore preferential
Rotational speed regulation is carried out to the fan group in specified services disk region, and then adjusts the temperature in the region, then to other
The fan group in region carries out rotational speed regulation, and then adjusts the temperature in other regions.By taking Fig. 6 as an example, since slot number Slot1 is corresponding
Service board be specified services disk, then first adjust the revolving speed of fan group 1, and then temperature control is realized to a-quadrant, then adjust other
The revolving speed of three fan groups, to realize the temperature control in the region B, C, D.
Embodiment 2:
In above-described embodiment 1, what each service board was reported between main control unit and each service board interaction is all actual measurement
Temperature, in another specific embodiment, related temperature can also be weighted temperature, now with each service board in rack
With the arrangement situation of fan group it is as shown in Figure 6 for, the application start of weighted temperature is discussed in detail.
In the step 10, when main control unit works normally, main control unit, which carries out temperature controlled process, can refer to Fig. 7,
Specifically includes the following steps:
Step 101, on the basis of any service board, the observed temperature of itself is weighted in each service board, is obtained
Corresponding weighted temperature, and the weighted temperature is reported to the main control unit.Wherein, for any slot position Slot i's
Service board, corresponding weighted temperature TiCalculation method are as follows:Wherein, Ti' be service board Slot i observed temperature
Value, TimaxFor the default dangerous temperature of service board Slot i, TmaxFor the default dangerous temperature of benchmark service board.Although each industry
The default dangerous temperature of business disk is different, but by weighted calculation, can will come in the unification a to standard of the temperature of each service board, more
Facilitate and compares or calculate.
Step 102, the main control unit obtains the weighted temperature of each service board every preset time poll, according to setting in advance
The weighted temperature of the temperature classification and each service board set determines the current temperature level of each service board, and then obtains temperature level
Array.
When wherein, to temperature classification, mainly to including TmaxCertain temperature range up and down inside carries out multiple temperature ranges
Division, and according to the sequence of temperature from low to high to each temperature range be arranged temperature level.To higher than TmaxBe lower than
TmaxTemperature range carry out the divisions of two temperature ranges respectively for, introduce the first temperature threshold and second temperature threshold value,
In, first temperature threshold is lower than Tmax, but relatively Tmax, for example may be configured as Tmax80%-100%；Described second
Temperature threshold is higher than Tmax, but be higher by seldom, for example may be configured as Tmax100%-120%.For being lower than the first temperature threshold
Temperature range, setting temperature level be 0；For the first temperature threshold and TmaxBetween temperature range, setting temperature level be
1；For TmaxWith the temperature range between second temperature threshold value, it is 2 that temperature level, which is arranged,；For being higher than second temperature threshold value
Temperature range, setting temperature level are 3.Temperature level is bigger, shows that temperature is higher, and the rotation speed of the fan needed is also bigger.
Assuming that the default dangerous temperature of Slot1, Slot2, Slot3 are respectively 100 DEG C, 40 on the basis of Slot1 service board
DEG C, 50 DEG C, the first temperature threshold and second temperature threshold value are respectively 90 DEG C, 110 DEG C, then temperature classification such as Fig. 8；For Slot2
With Slot3 service board, the temperature value in bracket indicates corresponding actual temperature value, and the temperature value outside bracket indicates weighted temperature.
According to above-mentioned temperature classification method, main control unit, can be by where weighted temperature value after the weighted temperature for obtaining each service board
After temperature range determines that affiliated temperature level, the temperature level of each service board determine, inserted in corresponding slot position
Corresponding temperature level specifically refers to Fig. 9 to obtain temperature level array, and slot number and temperature level correspond.
Step 103, according to the corresponding relationship of the rotation speed of the fan and temperature level array that pre-save, the main control unit is determined
Current desired rotation speed of the fan, and then adjust rotation speed of the fan.
Before carrying out temperature control, test of many times can be carried out in advance, determines the relationship of rotation speed of the fan Yu temperature level array,
The one-to-one relation table of the two is generated, and is stored in advance in main control unit and each service board.When according to above-mentioned steps 102
When obtaining temperature level array, main control unit can determine that fan corresponding with Current Temperatures level array turns directly from relation table
Speed, and then according to the revolving speed de-regulation fan, control temperature.Wherein, when each numerical value in temperature level array is 0
When, show that the weighted temperature of each service board is below the first temperature threshold, each single-deck keeps working normally, then continues fan
Current rotating speed operation is kept, without adjusting；When there are when any non-zero numerical value, then need according in advance in temperature level array
The mapping table of preservation determines the corresponding rotation speed of the fan of Current Temperatures level array, and according to the determining revolving speed to fan into
Row rotational speed regulation；Temperature level is higher in array, and the quantity of high-temperature rank is more, and the rotation speed of the fan needed is also bigger.
Temperature classification is weighted and be arranged by the observed temperature to each service board, has both been comprehensively considered each
The Current Temperatures and temperature requirement of service board in turn simplify the analysis treatment process to each service board temperature, by each service board
Come in temperature unification a to standard, the rotation speed of the fan of needs can be directly determined by temperature level array, realizes the equal of temperature
Weighing apparatus adjustment.
Correspondingly, in the step 20, when the main control unit operation irregularity, the specified services disk is also according to weighting
Temperature carries out temperature control, with specific reference to Figure 10, comprising the following steps:
Step 201, after the administration authority of the specified services disk adapter tube main control unit, each service board is obtained by information exchange
Weighted temperature.Since each service board can calculate the weighted temperature of itself according to the observed temperature of itself in real time, then the finger
The weighted temperature of each service board can be obtained by initiating information exchange by determining service board.
Step 202, according to the weighted temperature of pre-set temperature classification and each service board, the specified services disk is determined
The current temperature level of each service board, and then obtain temperature level array.The specified services disk is obtaining adding for each service board
