[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other. The invention will be described in detail below with reference to the figures and examples.
Example 1:
the embodiment of the invention provides a temperature control method of rack equipment, wherein a plurality of single disks are usually arranged in a rack, the single disks comprise a power panel, a main control panel and a service panel, and a plurality of fan sets are also arranged, and the temperature of the single disks is controlled by adjusting the rotating speed of fans in the fan sets, as shown in fig. 1, the temperature control method provided by the invention specifically comprises the following steps:
and step 10, obtaining the temperature of each single disk in the rack through temperature detection, and carrying out weighted calculation on the actually measured temperature of each single disk by taking any single disk as a reference to obtain the weighted temperature of each single disk.
In the rack, the requirements of each single disk on the working temperature are different, but each single disk corresponds to a limit temperature which can enable the single disk to keep normal working, namely the highest working temperature, and if the temperature exceeds the highest working temperature, the normal working of the single disk is influenced; before the temperature is detected, the highest working temperature corresponding to each single disc needs to be determined. After the measured temperature of each single disk is obtained, the weighted calculation of the temperature can be carried out through a processor in each single disk, and each single disk reports the weighted temperature to the master control disk; wherein for any single disk i, the weighted temperature T is correspondediThe calculation method comprises the following steps:
wherein, Ti' measured temperature value, T, for a single disk iimaxMaximum operating temperature, T, of a single disc imaxThe maximum operating temperature of the reference single disc.
And step 20, determining the current temperature level of each single disk according to a preset temperature grading method and the weighted temperature of each single disk, and further obtaining a temperature level array.
Wherein, when the temperature classification is performed in advance, T can be includedmaxDividing a plurality of temperature intervals at preset intervals in an upper and lower certain temperature range, and respectively setting temperature levels for each temperature interval according to the sequence of the temperature from low to high or from high to low, wherein the temperature levels can be specifically marked by numbers (0, 1 and 2.) or letters (a, b, c.. or A, B and C.); the preset interval can be set according to one or more of different working scene requirements, different working state requirements and different manufacturer customized requirements, and can also be determined through a preset test or determined by an operator according to experience. According to the temperature grading method, after the main control panel receives the weighted temperature reported by each single panel,the temperature class to which the temperature value belongs can be determined by weighting the temperature interval in which the temperature value belongs, each single disk can be labeled in advance according to the position distribution condition, and after the temperature classes of all the single disks are determined, the corresponding temperature classes are filled in the identification bits of the single disks, so that a temperature class array is obtained, and specifically, refer to fig. 2.
And step 30, determining the currently required fan rotating speed according to the corresponding relation of the fan rotating speed and the temperature level array which are stored in advance, and further adjusting the fan rotating speed.
Before temperature detection and control, multiple tests can be performed in advance to determine the relationship between the fan rotating speed and the temperature level array, a one-to-one corresponding relationship table of the fan rotating speed and the temperature level array is generated and stored in the main control panel in advance, when the temperature level array is obtained according to the step 20, the main control panel can directly determine the fan rotating speed corresponding to the current temperature level array from the relationship table, and then the fan is adjusted according to the rotating speed, so that the temperature of a single panel is controlled. When actually performing temperature control, the main control panel updates the temperature level array according to a preset period, for example, once every 1min, and then re-determines the current required fan rotation speed according to the latest temperature level array, so that the fans of the fan group can output according to the new rotation speed. Therefore, the loss caused by continuous operation of the main control panel can be avoided, the real-time control of the temperature in the rack can be realized, the rotating speed of the fan can meet the requirements of different single panels, and the normal work of each single panel is ensured.
According to the temperature control method of the rack equipment provided by the embodiment of the invention, the rotating speed of the fan is adjusted according to the current temperature of the single disks, so that the environmental temperature of the rack is controlled, and the effects of energy saving and noise reduction are achieved.
There are many ways to grade the temperature, usually TmaxIs a boundary line for a distance higher than TmaxCan be divided into one or more temperature intervals for temperatures below TmaxMay also be divided into one or more temperature intervals. In the embodiment of the invention, the pair is higher than TmaxAnd is lower than TmaxThe temperature ranges of (a) and (b) are divided into two temperature intervals respectively, and a temperature grading method is provided. For ease of description, a first temperature threshold and a second temperature threshold are introduced herein, wherein the first temperature threshold is below TmaxBut is relatively close to TmaxE.g. can be set to Tmax80% -100%; the second temperature threshold is higher than TmaxBut not much higher, e.g. set to Tmax100% -120%. The temperature grading method specifically comprises the following steps: for a temperature interval lower than a first temperature threshold value, the single disk can normally work, and the temperature level is set to be 0; for a first temperature threshold and TmaxIn the temperature interval, the single disk can still maintain normal operation, but is relatively close to the maximum operating temperature TmaxSetting the temperature level to 1; for TmaxAnd a temperature interval between the first temperature threshold and the second temperature threshold, the temperature of the single disk just exceeds TmaxEntering a state of incapable of normal operation, but still running, and setting the temperature level to be 2; for temperature intervals above a second temperature threshold, the single disk temperature exceeds TmaxMore, a temperature level of 3 is set. The greater the temperature level, the higher the temperature, and the greater the fan speed required.
According to the temperature grading method, in the process of executing the step 30, when each numerical value in the temperature grade array is 0, it indicates that the weighted temperature of each single disk is lower than the first temperature threshold value, each single disk keeps working normally, and the fan keeps running at the current rotating speed without adjustment; when any non-0 numerical value exists in the temperature level array, for example, 1, 2 or 3 exists, temperature adjustment is required, according to the corresponding relation between the pre-stored fan rotating speed and the numerical value in the temperature level array, the main control panel determines the fan rotating speed corresponding to the current temperature level array, and adjusts the rotating speed of the fan according to the determined rotating speed; wherein the higher the temperature levels in the array, the greater the number of high temperature levels, and the greater the required fan speed.
In combination with the embodiment of the present invention, there is also a preferred implementation scheme, where each single disk is provided with one or more temperature detection points, and in order to more accurately determine the temperature of the single disk, in the embodiment of the present invention, a plurality of temperature detection points are provided, each temperature detection point may represent the temperature in a certain area in the vicinity of the temperature detection point, and the plurality of temperature detection points may be uniformly distributed on the single disk, or distributed on each chip or device of the single disk, respectively, so as to be more representative. When a plurality of temperature detection points are set, the specific process of detecting the temperature of each single disk in the rack in the step 10 is as follows: for each single disc, respectively acquiring the temperature value of each temperature detection point on the single disc through temperature detection; and analyzing and processing the acquired temperature values of the temperature detection points, and taking the maximum value or the average value of the temperature values as the actually measured temperature of the single disk. After the measured temperatures of the single disks are obtained by the method, the measured temperatures of the single disks are weighted and calculated by taking any one of the single disks as a reference. Specifically, the temperatures of the plurality of temperature detection points can be respectively and correspondingly detected through the plurality of temperature sensors, and then the processor in the single disk compares the detected temperature values to obtain the maximum value, or the average value of the temperature values is obtained through calculation. By selecting a plurality of temperature detection points, the finally obtained single-disc temperature is more comprehensive and accurate and can represent the temperature of the whole single disc.
In combination with the embodiment of the present invention, there is also a preferred implementation scheme, before performing temperature detection and control, the inside of the rack is divided into at least two areas in advance according to the position distribution of each single disk and the position distribution of each fan group in the rack; wherein, each zone contains one or more single disks and a fan group responsible for controlling the temperature of the one or more single disks, that is, the single disk in each zone can be directly controlled by the fan group in the corresponding zone. When the fan rotation speed is adjusted in step 30, the fan rotation speeds of the fan groups in the respective areas may be adjusted according to the pre-divided areas, specifically: and searching a corresponding relation between the pre-stored fan rotating speed and the temperature level array according to an array formed by the temperature levels corresponding to the single disks in each area to obtain the currently required fan rotating speed of each area, and further driving the fans of the fan sets in each area to output the corresponding rotating speed, so as to realize the temperature regulation of the single disks in each area. The fan speed control device has the advantages that the control and the regulation are carried out by the areas, when the temperature of a certain area needs to be regulated, the fan speed regulation is only carried out on the fan group in the area, the unified regulation on all the fan groups in the rack is not needed, the temperature control is more targeted, the energy conservation is facilitated, and the service life of the fan is prolonged.
Example 2:
on the basis of the above embodiment 1, the present invention further provides a specific embodiment of a temperature control method for rack equipment. In this particular embodiment, it is assumed that there are 16 single disks in total for the single disk 1, the single disk 2, the single disk 3, the single disk 4, the. If the maximum working temperature of the single disc 1 is T1maxThe maximum working temperature of the single disc 2 is T100 DEG C2maxThe maximum working temperature of the single disc 3 is T40 deg.c3maxThe temperature is 50 ℃; and the maximum working temperature of the single disc 1 is taken as a reference, Tmax＝T1maxAt 100 ℃. The actual measurement temperatures of the single disk 1, the single disk 2 and the single disk 3 obtained by temperature detection are respectively assumed as follows: t is1’＝80℃、T2’＝30℃、T3' 60 ℃, since the single disc 1 is a reference single disc, the weighted temperature thereof is the measured temperature value: t is1＝T1' -80 deg.C, and continuing according to the formula
The weighted temperatures of the other individual disks can be found: t is2＝T2’×(Tmax/T2max)＝30×(100/40)＝75℃，T3＝T3’×(Tmax/T3max) 60 × (100/50) ═ 120 ℃, the rest monomersThe weighted temperature is also calculated by the same method for the disc and will not be described in detail here. When the working scene is changed, only the highest working temperature corresponding to the single disc needs to be adjusted and confirmed.
When temperature classification is performed in advance, the temperature of the single disk 1 is directly classified by the temperature of the reference, and the maximum operating temperature (100 ℃) is taken as a boundary, and the first temperature threshold is assumed to be 90 ℃ and the second temperature threshold is assumed to be 110 ℃. As shown in fig. 3, the temperature level is set to 0 in the temperature range of 90 ℃ or lower, 1 in the temperature range of 90 ℃ to 100 ℃, 2 in the temperature range of 100 ℃ to 110 ℃, and 3 in the temperature range of 110 ℃ or higher. Although in actual operation, the requirements of the individual disks for the operating temperatures are different, and the corresponding maximum temperatures are also different, the operating temperatures of the individual disks can be unified to a standard through weighting operation, and therefore, the weighted temperatures of all the individual disks can be set according to fig. 3. In this embodiment, as can be seen from the temperature classification method in fig. 3, if the weighted temperature of the single disk 1 is 80 ℃, the temperature level is 0, and the single disk 1 is in normal operation; the weighted temperature of the single disc 2 is 75 ℃, the temperature level is 0, and the single disc 2 works normally; the weighted temperature of the single disc 3 is 120 c and the temperature level is 3, indicating that the actual temperature of the single disc 3 has exceeded its maximum operating temperature by 50 c at this time. In fig. 3, for single disk 2 and single disk 3, the temperature values in parentheses represent the corresponding actual temperature values, and the temperature values outside the parentheses represent the weighted temperatures.
After the temperature levels are set for all the single disks according to the method, the obtained temperature level array is as shown in the right diagram in fig. 2, the array corresponds to the position distribution of the single disks one by one, or corresponds to the labels of the single disks one by one, the currently required fan rotating speed can be determined according to the corresponding relation of the fan rotating speed and the temperature level array which is stored in advance, and then the adjustment is completed according to the specified fan rotating speed, so that the temperature control is realized.
In a preferred scheme, the rack is divided into regions, so that different fan groups are respectively responsible for temperature control of single disks in corresponding regions, referring to fig. 4, in this embodiment, the rack is divided into A, B, C, D total 4 regions, each region has 4 single disks and 1 fan group, and after the temperature levels are set, 4 temperature level arrays as shown in the right diagram are correspondingly formed. At this time, 3 exist in the temperature level array corresponding to the area a, and all the temperature level arrays corresponding to the other three areas are 0, only the fan rotating speed of the fan group 1 needs to be determined through the lookup relation table and the rotating speed is adjusted, so that the temperature of the single disk in the area a is controlled, and the other three fan groups can continuously keep the current rotating speed to operate without adjustment.
The required fan rotating speed can be directly determined according to the temperature level array through weighted calculation and temperature grading, the process is simple, the energy-saving and noise-reducing effects are achieved, the current temperature and temperature requirements of each single disk are comprehensively considered, the analysis processing process of the temperature of each single disk is simplified, and the balanced adjustment of the temperature is realized; moreover, the fan group is used for regional control, so that the temperature regulation has pertinence, the energy consumption is further reduced, and the service life of the fan is prolonged.

And the management units are arranged in the service disks and the main control disk and are used for acquiring temperature values of the temperature detection points from the corresponding temperature detection units, then obtaining the maximum value of the temperature values through comparison, or obtaining the average value of the temperature values through calculation, taking the maximum value or the average value as the actual measurement temperature of the single disk, and further performing weighted calculation on the actual measurement temperature so as to obtain the weighted temperature corresponding to the single disk. Because the power panel is not provided with the management unit, the management unit can be managed by the main control panel in a bus mode, and the management unit in the main control panel can calculate the weighted temperature of the main control panel and can also calculate the weighted temperature of the power panel.
