[0047] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0048] Embodiment 1

[0049] Core board downclocking refers to lowering the operating frequency of the core board, that is, lowering the operating frequency of the core board's CPU (Central Processing Unit), thereby reducing the CPU's power consumption and CPU's operating temperature. When the core board's operating temperature (that is, the core board's CPU's operating temperature) is too high, lower the core board's CPU's operating frequency to ensure that the core board can run its business safely and normally without being burned.

[0050] The server contains a core board, which is used to support specific business functions. In order to protect the normal operation of the core board on the server from being burned, existing servers usually adopt a unified frequency reduction strategy for all core boards: a frequency reduction temperature is set in the server, and when the operating temperature of the core board, that is, the temperature of the core board's central processor, is detected to be greater than the frequency reduction temperature, the operating main frequency of the core board's central processor is reduced, thereby reducing the operating temperature of the core board and protecting the core board from being burned. However, such a fixed and single frequency reduction strategy cannot take into account the differences between core boards and achieve differentiated frequency reduction of core boards.

[0051] Usually, under the premise of ensuring the normal operation of the core board and not being burned, the actual operating performance of all core boards should be kept consistent as much as possible. This requires taking into account the differences between the core boards and achieving differentiated frequency reduction of the core boards. For example, in order to keep the actual operating performance of all core boards as consistent as possible, under the same operating temperature, the frequency reduction temperature of the core board with high actual operating performance should be lower than the frequency reduction temperature of the core board with low actual operating performance.

[0052] It is understandable that due to differences in the performance of the core boards themselves or other factors, there may be differences in the actual operating performance of the core boards. For example, assuming that the wind direction of the cooling fan in the server is from right to left, the heat generated by the core board near the right will be blown to the core board near the left, and the CPU load of the core board on the right is greater than that on the left, that is, at the same operating temperature, the actual operating performance of the core board on the right is higher than that of the core board on the left.

[0053] Based on this, the present application proposes a method for reducing the frequency of a server in the first embodiment, please refer to Figure 1 , the server includes a plurality of core boards, and the frequency reduction method of the server includes:

[0054] Step S10, obtaining the current operating temperature and the frequency reduction temperature corresponding to each core board, wherein each core board is correspondingly set with a frequency reduction temperature;

[0055] It is known to those skilled in the art that the current operating temperature of the core board can be the current operating temperature of the CPU of the core board, that is, the current operating temperature of the CPU. In order to keep the actual operating performance of all core boards as consistent as possible, at the same operating temperature, the frequency reduction temperature of the core board with high actual operating performance is set to be lower than the frequency reduction temperature of the core board with low actual operating performance. For example, refer to Figure 2, there are 9 core boards in the server, namely core board 1, core board 2, core board 3, core board 4, core board 5, core board 6, core board 7, core board 8, and core board 9. During the operation of the core boards, the air flow direction of the cooling fan in the server blows from the right core boards to the left core boards. During the operation of the core boards, the heat generated by the right core boards will be blown to the left. That is, under the same temperature condition, the load of the right CPU is greater than that of the left (the hot air flow on the right will cause the CPU of the left core board to heat up), resulting in inconsistent actual performance between the left and right core boards. At this time, the dynamic adjustment of the downclocking strategy can be achieved by setting the downclocking temperature of the right core board to be lower than that of the left core board, so as to ensure that the actual operating performance of all core boards on the server is as consistent as possible. Exemplarily, the downclocking temperatures of core board 1, core board 2, and core board 3 can be set to T1, the downclocking temperatures of core board 4, core board 5, and core board 6 can be set to T2, and the downclocking temperatures of core board 7, core board 8, and core board 9 can be set to T3. Preferably, T1 < T2 < T3, and it is assumed that the current working temperatures of the CPUs of the 9 core boards are [R1, R2, R3, R4, R5, R6, R7, R8, R9]. Then, the current working temperature and downclocking temperature corresponding to each core board obtained in this scenario can be referred to as shown in Table 1.

[0056] Core board Current operating temperature Throttling Temperature Core board 1 R1 T1 Core board 2 R2 T1 Core board 3 R3 T1 Core board 4 R4 T2 Core board 5 R5 T2 Core board 6 R6 T2 Core board 7 R7 T3 Core board 8 R8 T3 Core board 9 R9 T3

[0057] Table 1

[0058] Furthermore, the downclocking temperature of each core board can be set in advance, and the downclocking temperature of each core board is associated and set in the target downclocking strategy table. For example, the core board identifier of each core board is associated and set with the corresponding downclocking temperature in the target downclocking strategy table, so that the corresponding downclocking temperature can be found from the target downclocking strategy table through the core board identifier of each core board.

[0059] Step S20, sequentially detect whether each of the core boards meets the preset downclocking condition, and use the core board that meets the preset downclocking condition as the target core board, where the preset downclocking condition includes that the current working temperature corresponding to the detected core board is greater than or equal to the downclocking temperature corresponding to the detected core board;

[0060] Check one by one whether the current operating temperature of each core board is greater than or equal to its corresponding frequency reduction temperature. If the current operating temperature of a core board is greater than or equal to its corresponding frequency reduction temperature, then this core board is the target core board that meets the preset frequency reduction conditions. For example, based on the example of 9 core boards in the above-mentioned server, assuming that the current operating temperatures (in degrees Celsius) of the CPUs of the 9 core boards are [58.5, 60.5, 65.5, 59.8, 72.1, 57.8, 60.5, 73.5, 81.1], and their corresponding frequency reduction temperatures (in degrees Celsius) are [60, 60, 60, 70, 70, 70, 80, 80, 80], then the target core boards are [core board 2, core board 3, core board 5, core board 9].

[0061] Step S30, reducing the operating frequency of the target core board, wherein the operating frequency includes the main operating frequency of the central processing unit of the target core board.

[0062] For the target core board whose current operating temperature is greater than or equal to the frequency reduction temperature, the operating frequency of the target core board is reduced, that is, the CPU operating main frequency of the target core board is reduced. In the above example, the CPU operating main frequency of core board 2, core board 3, core board 5 and core board 9 is reduced.

[0063] In this embodiment, the current operating temperature and frequency reduction temperature corresponding to each core board are obtained, and a frequency reduction temperature is set correspondingly by each core board, and each core board is detected in turn whether the preset frequency reduction condition is met, and the core board that meets the preset frequency reduction condition is used as the target core board, wherein the preset frequency reduction condition includes that the current operating temperature corresponding to the detected core board is greater than or equal to the frequency reduction temperature corresponding to the detected core board, then the target core board whose current operating temperature is greater than or equal to the frequency reduction temperature is frequency reduced, that is, the operating frequency of the target core board is reduced, such as reducing the working main frequency of the central processing unit of the target core board. In this way, compared with the prior art setting a frequency reduction temperature in the server, when the operating temperature of any core board is greater than or equal to this frequency reduction temperature, the core board is frequency reduced, in the embodiment of the present application, each core board is correspondingly set to a frequency reduction temperature, when the current operating temperature of the core board is greater than or equal to its corresponding frequency reduction temperature, the core board is frequency reduced, so that the differentiated frequency reduction of the core board can be achieved by setting different frequency reduction temperatures of the core board.

[0064] In a possible implementation, before the step of obtaining the current operating temperature and the frequency reduction temperature corresponding to each core board according to the upgraded firmware data, the method further includes:

[0065] A10, performing grouping processing on each of the core boards to obtain a plurality of core board groups, and setting a first frequency reduction temperature corresponding to each of the core board groups to obtain a frequency reduction strategy table;

[0066] As an example, when the CPU temperature of the core board reaches the same operating temperature, the core boards with consistent actual CPU performance can be grouped as a group. The actual performance is consistent, and the difference between the actual performance is less than the preset difference percentage, wherein the preset difference percentage can be arbitrarily set such as 3%, 5%, and further, the CPU usage of the core board can be used as a criterion for judging the actual performance. For example, assuming that when the CPU operating temperature of 9 core boards (core boards 1 to 9) reaches 80 degrees Celsius, the corresponding CPU usage rates are [90%, 91%, 92%, 80%, 81%, 82%, 70%, 71%, 72%], and the preset difference percentage is 3%, then {core board 1, core board 2, core board 3} can be grouped as a core board, {core board 4, core board 5, core board 6} as a core board group, {core board 7, core board 8, core board 9} as a core board group.

[0067] As another example, the core boards can be grouped according to their actual locations. Figure 2 For example, for Figure 2 For the 9 core boards in the system, if the wind direction is from right to left, the core boards in the same column can be grouped as one core board, that is, {core board 1, core board 2, core board 3} as one core board group, {core board 4, core board 5, core board 6}, {core board 7, core board 8, core board 9} as one core board group. If the wind direction is from top to bottom, the core boards in the same row can also be grouped as one group.

[0068] It should be noted that the grouping of the core board can be stored in a grouping table, and the core board identification of the core board is recorded in the group in which it is located. The form of the grouping table can be shown in Table 2 below. In addition, if a grouping table is set in advance in the server, such as a grouping table set in advance by the user, the core board can be grouped again without regrouping the core board, and the core board group in which the core board is located can be determined directly by matching the core board identification.

[0069] Core board grouping Core board identification Group 1 Core board 1, core board 2, core board 3 Group 2 Core board 4, core board 5, core board 6 Group 3 Core board 7, core board 8, core board 9

[0070] Table 2

[0071] To set the frequency reduction temperature of each core board group, it is understandable that each core board can be numbered to obtain the group number of each core board group, and the group number corresponding to each core board group is associated with the frequency reduction temperature and stored in the frequency reduction strategy table. Assuming that the frequency reduction temperatures set for group 1, group 2, and group 3 in the above example are T1, T2, and T3 respectively, the contents included in the frequency reduction strategy table can refer to Table 3. In addition, it should be noted that the frequency reduction strategy table can also be set in advance by the user. If the frequency reduction strategy table is set in advance in the server, the frequency reduction strategy table can be directly obtained. The frequency reduction strategy table in the embodiment of the present application is an exemplary description, and no specific limitation is made to the frequency reduction strategy table.

[0073] Table 3

[0074] A20, traversing each of the core boards in turn, and taking the traversed core board as the first core board;

[0075] A30, determining a first core board group where the first core board is located according to the multiple core board groups, and determining a first frequency reduction temperature corresponding to the first core board group in the frequency reduction strategy table;

[0076] The grouping table can be matched by the core board identification of the first core board identification, so that the first core board group where the first core board is located is determined by matching the frequency reduction strategy table. For example, assuming that the grouping table is shown in Table 2, the frequency reduction strategy table is shown in Table 3. The core board identification of the first core board is core board 1, then the matching grouping table determines that the first core board group is group 1, and then matches the frequency reduction strategy table to determine that the frequency reduction temperature corresponding to group 1 is T1.

[0077] A40: Use the first frequency reduction temperature corresponding to the first core board group as the frequency reduction temperature corresponding to the first core board.

[0078] The first frequency reduction temperature obtained by matching the frequency reduction strategy table is used as the frequency reduction temperature of the first core board. Thus, after traversing all core boards, the frequency reduction temperature of each core board can be determined. It can be understood that after the frequency reduction temperature corresponding to each core board on the server is determined by the present embodiment, the core board identifier corresponding to each core board can be associated with the frequency reduction temperature and stored to obtain the target frequency reduction strategy table, and the target frequency reduction strategy table is stored. The target frequency reduction strategy table can be shown in Table 4. Thus, the frequency reduction temperature corresponding to each core board can be directly obtained by searching the target frequency reduction strategy table to execute step S10.

[0080] Table 4

[0081] In an practicable manner, the step of grouping the core boards to obtain a plurality of core board groups, and setting a first frequency reduction temperature corresponding to each core board group to obtain a frequency reduction strategy table includes:

[0082] Step B10, determining the first usage rate corresponding to each of the core boards when the operating temperature of each of the core boards is a preset temperature;

[0083] The preset temperature can be set by the user in advance or determined by statistical means of experiments. Figure 2 Take the 9 core boards in the example, count the CPU temperature of the core boards in the rightmost column, i.e., core board 1, core board 2, and core board 3, in the preset business application scenario, and take the average value of the CPU temperature obtained by statistics to obtain the preset temperature. Among them, the preset business application scenario can count the CPU temperature of the core boards in several business application scenarios, and select the business application scenario with the highest CPU temperature as the preset business application scenario. For example, the average value of the CPU temperature of the core boards of core boards 1, core board 2, and core board 3 in business application scenario 1 is 40 degrees Celsius, the average value of the CPU temperature of the core boards in business application scenario 2 is 50 degrees Celsius, and the average value of the CPU temperature in business application scenario 3 is 60 degrees Celsius. Then, the preset business application scenario can be business application scenario 3. The CPU temperature of core boards 1, core board 2, and core board 3 in the preset business application scenario can be measured multiple times, and the preset temperature can be obtained by taking the average value. If the CPU temperatures of core board 1, core board 2, and core board 3 in the preset business application scenario in n measurements are {(T1.1, T2.1, T3.1), (T1.2, T2.2, T3.2)......(T1.i, T2.i, T3.i)......(T1.n, T2.n, T3.n)} respectively, then the preset temperature can be set to TA=((T1.1+T2.1+T3.1)+......+(T1.i+T2.i+T3.i)+......+(T1.n, T2.n, T3.n)) / 3*n.

[0084] The preset temperature is recorded as TA. When the operating temperature of each core board is determined to be TA, the first usage rate corresponding to each core board is determined. The usage rate can be the CPU usage rate of the core board. Similarly, for each core board, the CPU operating temperature of the core board can be measured multiple times to reach TA, and the usage rate of the core board can be counted. Then, the average of the counted usage rates can be taken to obtain the first usage rate corresponding to each core board.

[0085] Step B20, grouping the core boards with the same first usage rate as a core board group, and setting a first frequency reduction temperature corresponding to each of the core board groups;

[0086] Among them, the first usage rate is consistent, and the difference between the first usage rates can be less than the preset difference percentage, and the first usage rate is considered to be consistent. Among them, the preset difference percentage can be arbitrarily set such as 3%, 5%. For example, assuming that the CPU operating temperature of 9 core boards (core boards 1-9) reaches TA degrees Celsius, it is statistically obtained that the CPU usage rates corresponding to each core board are [90%, 91%, 92%, 80%, 81%, 82%, 83%, 70%, 71%, 72%], and the preset difference percentage is 3%. Then {core board 1, core board 2, core board 3} can be regarded as a core board group (which can be recorded as group 1), {core board 4, core board 5, core board 6} can be regarded as a core board group (which can be recorded as group 2), and {core board 7, core board 8, core board 9} can be regarded as a core board group (which can be recorded as group 3).

[0087] Set the first frequency reduction temperature corresponding to each core board group. In order to keep the actual operating performance of the core board as consistent as possible, the lower the first usage rate corresponding to the core board group, the higher the frequency reduction temperature of this core board is set. The first usage rate corresponding to group 1 is recorded as UA, the first usage rate corresponding to group 2 is recorded as UB, and the first usage rate corresponding to group 3 is recorded as UC. UA>UB>UC, the frequency reduction temperatures of group 1, group 2 and group 3 can be set to T1, T2, and T3 respectively. T1 <T2<T3。

[0088] Step B30, numbering each core board group to obtain a group number of each core board group, and associating and storing the group number, the first usage rate and the first frequency reduction temperature corresponding to each core board group to obtain a frequency reduction strategy table.

[0089] The frequency reduction strategy table is obtained by associating and storing the group number, the first usage rate and the first frequency reduction temperature corresponding to each core board group. The content of the frequency reduction strategy table may be as shown in Table 5.

[0090] Core board grouping Utilization Throttling Temperature Group 1 UA T1 Group 2 UB T2 Group 2 UC T3

[0091] Table 5

[0092] In this embodiment, when the operating temperature of each core board reaches the same preset temperature, its respective first usage rate is counted, and the core boards with the same first usage rate are grouped as a core board. The same frequency reduction temperature is set for the core boards belonging to the same core board group, that is, for the same operating temperature, different frequency reduction temperatures are set for core boards with different usage rates, thereby realizing dynamic adjustment of the frequency reduction strategy, and the group number corresponding to each of the core board groups, the first usage rate and the first frequency reduction temperature are associated and stored to obtain a frequency reduction strategy table. By looking up the frequency reduction strategy table, the frequency reduction temperature of the core board can be effectively obtained, thereby improving the convenience of obtaining the frequency reduction temperature of the core board.

[0093] In an practicable manner, the step of setting the first frequency reduction temperature corresponding to each core board group includes:

[0094] Step C10, traversing each of the core board groups in turn, and determining the second core board included in the traversed core board group;

[0095] Step C20, determining the second operating temperature of the second core board when the usage rate of the second core board is a preset usage rate, and adjusting the second operating temperature to obtain an adjusted second operating temperature;

[0096] Wherein, the preset usage rate can be the maximum first usage rate among the first usage rates of each core board grouping when the core board CPU operating temperature reaches the preset temperature. Then it can be understood that the second operating temperature of the second core board included in the core board grouping corresponding to the maximum first usage rate is the preset temperature. As in the above example, the preset usage rate is set to the first usage rate UA of grouping 1, and the second operating temperature of the second core board included in grouping 1 is TA. If a core board grouping includes multiple core board groups, the corresponding operating temperatures of each second core board usage rate when reaching the preset usage rate are counted, and the average value is taken as the corresponding second operating temperature when the usage rate of this core board grouping reaches the preset usage rate. And it is also possible to experimentally measure the corresponding operating temperature when the usage rate of the second core board reaches the preset usage rate for multiple times, and then take the average value to obtain the second operating temperature of the second core board. For example, a core board group includes three core boards, namely core board 4, core board 5, and core 6. When the usage rate of core board 4, core board 5, and core board 6 reaches the preset usage rate UA in n measurements, the corresponding operating temperatures are {(T4.1, T5.1, T6.1), (T4.2, T5.2, T6.2)......(T4.i, T5.i, T6.i)......(T4.n, T5.n, T6.n)}, then the second operating temperature TB of the second core board included in this core board group = ((T4.1+T5.1+T6.1)+......+(T4.i+T5.i+T6.i)+......+(T4.n, T5.n, T6.n)) / 3*n.

[0097] It should be noted that the adjustment of the second operating temperature corresponding to each core board group can be to add a preset redundancy value to the second operating temperature, or to multiply the second operating temperature by a preset redundancy coefficient. Preferably, the adjusted second operating temperature is greater than the second operating temperature before adjustment. If the preset redundancy value is a positive value, the preset redundancy coefficient is greater than one. The specific adjustment method is not limited in this embodiment.

[0098] Step C30: Using the adjusted second operating temperature as the first frequency reduction temperature corresponding to the traversed core board group, so as to obtain the first frequency reduction temperature corresponding to each core board group after the traversal is completed.

[0099] It can be seen that after the traversal, the second operating temperature of the core board included in each group is determined. Taking the three core board groups of the above nine core boards as an example, the second operating temperature corresponding to group 1 is recorded as TA, the second operating temperature corresponding to group 2 is recorded as TB, and the second operating temperature corresponding to group 3 is recorded as TC. And the corresponding adjusted second operating temperatures are recorded as T1, T2, and T3, respectively, where T1>TA, T2>TB, T3>TC, and the first frequency reduction temperature corresponding to group 1 is set to T1, the first frequency reduction temperature corresponding to group 2 is set to T2, and the first frequency reduction temperature corresponding to group 3 is set to T3.

[0100] In this embodiment, each of the core board groups is traversed in sequence to determine the second core board included in the traversed core board group; when the utilization rate of the second core board is determined to be the preset utilization rate, the second operating temperature of the second core board is adjusted to obtain the adjusted second operating temperature; the adjusted second operating temperature is used as the first frequency reduction temperature corresponding to the traversed core board group, so as to obtain the first frequency reduction temperature corresponding to each of the core board groups after the traversal is completed. That is, each core board group is adaptively adjusted to the corresponding operating temperature at the same preset utilization rate as its corresponding frequency reduction temperature, so as to ensure that the CPU utilization rate corresponding to the frequency reduction temperature set for each core board is relatively consistent, that is, when the operating temperature of each core board reaches the frequency reduction temperature for frequency reduction, the CPU utilization rate of the core board is kept relatively consistent, which guarantees that the actual operating performance of all core boards on the server remains consistent to the greatest extent possible.

[0101] In an implementable manner, the step of determining the first core board group in which the first core board is located according to the plurality of core board groups includes:

[0102] Step D10, determining a second usage rate of the first core board when the operating temperature of the first core board is a preset temperature;

[0103] Step D20, determining a target usage rate that matches the second usage rate among the first usage rates in the frequency reduction strategy table;

[0104] Step D30, determining a target group number corresponding to the target usage rate in the frequency reduction strategy table, and using the target group number as the first core board group where the first core board is located.

[0105] Among them, the matching of the second usage rate with each first usage rate can be to determine the first sub-usage rate in each first usage rate that is greater than or equal to the second usage rate, and determine the largest first sub-usage rate in each first sub-usage rate as the target usage rate in each first usage rate that matches the second usage rate. For example, with the above-mentioned 9 core boards, the frequency reduction strategy table can be shown in Table 5, wherein UA>UB>UC, assuming that the second usage rate of the first core board is greater than or equal to UA, then the target usage rate is UA, and the corresponding target group number is group 1, the second usage rate of the first core board is greater than or equal to UB and less than UA, then the target usage rate is UB, and the corresponding target group number is group 2, the second usage rate of the first core board is greater than or equal to UC and less than UB, then the target usage rate is UC, and the corresponding target group number is group 3.

[0106] In order to help understand the technical concept or technical principle of the present application, a specific embodiment is listed:

[0107] The frequency reduction process in this specific embodiment is as follows:

[0108] Reference Figure 2 , insert 9 core boards into the server, and then all the core boards run the customer's business at the same time.

[0109] During the operation of the core board, the wind flows from the right to the left, that is, the heat generated by the right core board will be blown to the left. That is, under the same temperature, the load of the CPU on the right is greater than that on the left. The 9 core boards are divided into three core board groups. The core boards in the rightmost column are recorded as core board group 1, the core boards in the middle column are recorded as core board group 2, and the core boards in the leftmost column are recorded as core board group 3.

[0110] (1) Count the CPU temperature of the core board in the rightmost column under the customer business application scenario, record this temperature value as TA, set the frequency reduction temperature to T1, T1 is slightly higher than TA, and record the CPU usage at this temperature, recorded as UA. When the temperature of the core board exceeds T1, the CPU will be frequency reduced, the same below.

[0111] (2) When the CPU usage of the core board in the middle column is UA, the CPU temperature at this time is recorded as TB, the frequency reduction temperature is set to T2, which is slightly higher than TB, and the CPU usage is recorded as UB when the temperature is TA.

[0112] (3) When the CPU usage of the core board in the leftmost column is UA, the CPU temperature at this time is recorded as TC, and the frequency reduction temperature is set to T3, which is slightly higher than TC. At the same time, the CPU usage is recorded as UC when the temperature is TA.

[0113] (4) Combined with the statistical values ​​of the first three steps, three sets of frequency reduction strategies are preset in the core board

[0114] Strategy 1, the corresponding temperature is TA, the CPU usage is UA, and the frequency reduction temperature is T1

[0115] Strategy 2, the corresponding temperature is TA, the CPU usage is UB, and the frequency reduction temperature is T2

[0116] Strategy 3, the corresponding temperature is TA, the CPU usage is UC, and the frequency reduction temperature is T3

[0117] The core board can work normally at three temperatures: TA, TB, and TC. It can also work normally before the temperature drops below T3, and will not cause the core board to burn out due to high temperature. <TB<TC

[0118] (5) When the core board is inserted into the server to run customer business, the CPU usage rate is determined when the core board reaches the TA temperature.

[0119] If the CPU usage is UA, the throttling temperature is adjusted to T1.

[0120] If the CPU usage is UB, adjust the throttling temperature to T2.

[0121] If the CPU usage is UC, adjust the throttling temperature to T3.

[0122] If the CPU usage is greater than UB and less than UA, the frequency reduction temperature is adjusted to T2.

[0123] If the CPU usage is greater than UC and less than UB, the frequency reduction temperature is adjusted to T3.

[0124] It should be noted that the above specific embodiments are only used to understand the present application and do not constitute a limitation on the frequency reduction method of the server of the present application. More simple transformations based on this technical concept are all within the protection scope of the present application.

[0125] Embodiment 2

[0126] Based on the first embodiment of the present application, in another embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , the step of reducing the operating frequency of the target core board comprises:

[0127] Step E10, determining the target current operating temperature of the target core board, and determining a temperature level in a preset temperature level table that matches the target current operating temperature;

[0128] Step E20, determining the frequency reduction step corresponding to the temperature level in the preset temperature level table, and reducing the operating frequency of the target core board based on the frequency reduction step.

[0129] In the present embodiment, the temperature level table may include the frequency reduction pace corresponding to the temperature level of different operating temperatures. Generally, the higher the operating temperature, the larger the corresponding frequency reduction pace, and the faster the operating frequency of the target core board decreases. For example, the temperature level of the operating temperature can be divided into three levels: the first level (operating temperature 70-80 degrees Celsius), the second level (spacing 80-90 degrees Celsius), and the third level (90-100 degrees Celsius). If the target current operating temperature of the target core board is in the first temperature level, the frequency reduction pace can be 5% of the current operating frequency, if the target current operating temperature of the target core board is in the second temperature level, the frequency reduction pace can be 8% of the current operating frequency, and if the target current operating temperature of the target core board is in the third temperature level, the frequency reduction pace can be 10% of the current operating frequency. In other words, the higher the current operating temperature, the larger the corresponding frequency reduction pace.

[0130] In this embodiment, the target current operating temperature of the target core board is determined, and the temperature level in the preset temperature level table that matches the target current operating temperature is determined; the frequency reduction step corresponding to the temperature level in the preset temperature level table is determined, and the operating frequency of the target core board is reduced based on the frequency reduction step. Different temperature levels of the target current temperature correspond to different frequency reduction steps. The higher the current operating temperature, the larger the corresponding frequency reduction step, and the more the operating frequency of the core board is reduced, thereby improving the flexibility of frequency reduction and ensuring the safe operation of the core board without being burned.

[0131] In a possible implementation manner, after the step of determining the target current operating temperature of the target core board, the method further includes:

[0132] Step E30: if the target current temperature is lower than the preset maximum temperature, a step of determining a temperature level in a preset temperature level table that matches the target current operating temperature is performed.

[0133] Step E40: If the target current temperature is greater than or equal to the preset maximum temperature, interrupt the operation of the target core board, or control the target core board to enter a shutdown state.

[0134] In this embodiment, if the target current temperature is greater than or equal to the preset maximum temperature, such as 95 degrees Celsius, the operation of the target core board is interrupted, or the target core board is controlled to enter a shutdown state, that is, the core board operating temperature is greater than or equal to the preset maximum temperature. When an abnormal operating temperature occurs, the core board is controlled to stop running, further avoiding the phenomenon of continuing to run the business when the core board operating temperature is abnormal, which may cause the core board to be burned, thereby ensuring the safe operation of the core board.
