Description

Technical Field

[0001] The present invention relates to the field of fan control, and in particular to a fan speed regulation method, a fan, a computer device and a storage medium. Background Art

[0002] In the existing technology, the main architecture of the server fan speed control method is composed of the key component PID speed control mechanism. The PID speed control mechanism is a single target mechanism, that is, setting a temperature target point. The single target point leads to the following problems:

[0003] 1. Setting the target point too high: This may cause the temperature of key components to fail to reach the PID speed control mechanism. However, if the speed control mechanism is set too low due to the noise demand environment, key components will operate at relatively high temperatures. High temperatures can easily cause component failure.

[0004] 2. The target point is set too low: This may cause the temperature of key components to easily reach the PID speed control mechanism, leading to increased investment in cooling resources: the speed increases, and the noise and power increase.

[0005] 3. Setting the target point midway: This balances cooling performance and cooling resource efficiency. However, for specific users, this is only a compromise and does not take into account individual user habits.

[0039] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with preferred embodiments and accompanying drawings. Similar components in the accompanying drawings are represented by the same reference numerals. It should be understood by those skilled in the art that the following detailed description is illustrative rather than restrictive and should not be used to limit the scope of protection of the present invention.

[0040] According to the problems existing in the prior art, such as Figure 1 As shown, an embodiment of the present invention provides a fan speed regulation method, comprising:

[0041] Acquire the ambient temperature and key component temperature in real time based on the temperature sensor set on the target device;

[0042] Obtaining a first fan speed corresponding to the ambient temperature according to a preset temperature and speed configuration table, wherein the temperature and speed configuration table includes different temperatures and fan speeds corresponding to each temperature;

[0043] Obtaining a second fan speed corresponding to the temperature of the key component according to a preset PID speed regulation algorithm, wherein the PID speed regulation algorithm includes at least two temperature target points;

[0044] The fan speed is adjusted according to the higher value of the first fan speed and the second fan speed.

[0045] In this embodiment, the fan speed corresponding to the temperature of the key component is obtained by a PID speed control algorithm including at least two temperature target points, and the fan speed is adjusted according to a first fan speed corresponding to the ambient temperature and a second fan speed obtained by the PID speed control algorithm corresponding to the temperature of the key component. This can meet different heat dissipation requirements and has broad application prospects.

[0046] In a specific example, the fan speed corresponding to the acquired ambient temperature is first obtained from a predefined temperature and speed configuration table. The table includes temperatures and fan speeds that correspond to each temperature, i.e., one fan speed corresponds to one ambient temperature. Based on the real-time acquired ambient temperature of the target device, the corresponding first fan speed is obtained. Then, based on the acquired key device temperature, the corresponding second fan speed is obtained using a PID speed control algorithm.

[0047] In order to solve the problem that setting a single temperature target point in the existing technology cannot meet different needs, such as Figure 2 As shown, the PID speed control algorithm of this embodiment includes a nonlinear step curve L of temperature and speed formed by three temperature target points T1, T2 and T3, and the nonlinear step curve includes multiple segments of curves. The corresponding fan speed is obtained according to the nonlinear step curve based on the real-time acquired key component temperature.

[0048] In this embodiment, the nonlinear step curve L includes a horizontal line L1 corresponding to the temperature target point T1, a horizontal line L2 corresponding to the temperature target point T2, and a horizontal line L3 corresponding to the temperature target point T3, as well as a broken line L4 located between the horizontal lines L1 and L2, and a broken line L5 located between the horizontal lines L2 and L3.

[0049] Specifically, the nonlinear step curve L includes horizontal lines L1, L2 and L3 corresponding to the temperature target points, and the fan speed corresponding to each horizontal line is the fan speed corresponding to the temperature target point. For example, the fan speed corresponding to the horizontal line L1 is the fan speed of 4000 corresponding to the temperature target point T1, the fan speed corresponding to the horizontal line L2 is the fan speed of 8000 corresponding to the temperature target point T2, and the fan speed corresponding to the horizontal line L3 is the fan speed of 16000 corresponding to the temperature target point T3. The temperature starting point and temperature end point corresponding to the horizontal lines are the lower temperature limit and the upper temperature limit with the temperature target point as the midpoint and the preset temperature amplitude as the step. For example, the temperature starting point corresponding to the horizontal line L1 is the temperature of the temperature target point T1, which is 45 degrees, minus the preset temperature amplitude of 5 degrees, which is 40 degrees. Similarly, the temperature end point corresponding to the horizontal line L1 is the temperature of the temperature target point T1, which is 45 degrees, plus the preset temperature amplitude of 5 degrees, which is 50 degrees. That is, each horizontal line represents the temperature range corresponding to each temperature target. Horizontal line L1 is the temperature range of 40 to 50 degrees corresponding to the temperature target point T1 of 45 degrees. The fan speed corresponding to the temperature of each key component within this temperature range is the same 4000; horizontal line L2 is the temperature range of 60 to 70 degrees corresponding to the temperature target point T2 of 65 degrees. The fan speed corresponding to the temperature of each key component within this temperature range is the same 8000; horizontal line L3 is the temperature range of 80 to 90 degrees corresponding to the temperature target point T3 of 85 degrees. The fan speed corresponding to the temperature of each key component within this temperature range is the same 16000.

[0050] Broken line L4 is the broken line between horizontal line L1 at temperature target point T1 and horizontal line L2 at temperature target point T2 in the nonlinear step curve L. Broken line L4 is a linear curve. The fan speed at the starting point of broken line L4 is 4000 for temperature target point T1, and the fan speed at the end point of broken line L4 is 8000 for temperature target point T2. The temperature at the starting point of broken line L4 is the upper temperature limit of 50°C for horizontal line L1, and the temperature at the end point of broken line L4 is the lower temperature limit of 60°C for horizontal line L2. The fan speeds corresponding to the key component temperatures along broken line L4 are arranged according to a linear rule, that is, the corresponding fan speeds are obtained on broken line L4 based on the key component temperatures. Similarly, as shown in the figure, the starting point of broken line L5 is the fan speed of 8000 corresponding to the upper temperature limit of 70°C for horizontal line L2, and the end point of broken line L5 is the fan speed of 16000 corresponding to the lower temperature limit of 80°C for horizontal line L3. The fan speeds corresponding to the key component temperatures along broken line L5 are arranged according to a linear rule.

[0051] Based on the real-time temperature of key components, the corresponding second fan speed is obtained according to the PID speed control algorithm, especially the fan speed corresponding to each stage line segment formed according to the set different temperature target points. By comparing the obtained first fan speed and second fan speed, the fan speed value is adjusted according to the fan speed with the higher speed, thereby achieving the setting of different temperature target points through the PID speed control algorithm, and further obtaining the second fan speed corresponding to the key component temperature according to the different temperature target points, thereby avoiding the problems in the prior art when the target point is set too high, too low or in the middle due to setting a single temperature target point, and can meet different heat dissipation requirements.

[0052] In another specific embodiment, Figure 3 As shown, the PID speed control algorithm of this embodiment includes a nonlinear step curve N of temperature and speed formed by three temperature target points T1, T2 and T3, and the nonlinear step curve includes multiple segments of curves. The corresponding fan speed is obtained according to the nonlinear step curve based on the key component temperature obtained in real time.

[0053] In this embodiment, the nonlinear step curve N includes a curve N1 corresponding to the temperature target point T1, a curve N2 corresponding to the temperature target point T2, and a curve N3 corresponding to the temperature target point T3, as well as a curve N4 located between the curves N1 and N2, and a curve N5 located between the curves N2 and N3.

[0054] Specifically, the nonlinear step curve N includes curves N1, N2 and N3 corresponding to the temperature target points, and the fan speed corresponding to each curve is a preset fan speed. For example, the temperature range corresponding to curve N1 is 40 degrees to 50 degrees centered on the temperature target point T1 of 45 degrees. Curve N1 is a linear curve from a fan speed of 2500 corresponding to the starting point of 40 degrees to a fan speed of 4000 corresponding to the end point of 50 degrees. The fan speeds corresponding to the key component temperatures on curve N1 are arranged according to a nonlinear rule; similarly, curve N2 is a linear curve from a fan speed of 6000 corresponding to the starting point of 60 degrees to a fan speed of 8000 corresponding to the end point of 70 degrees. The fan speeds corresponding to the key component temperatures on curve N2 are arranged according to a nonlinear rule; curve N3 is a linear curve from a fan speed of 13000 corresponding to the starting point of 80 degrees to a fan speed of 16000 corresponding to the end point of 90 degrees. The fan speeds corresponding to the key component temperatures on curve N3 are arranged according to a nonlinear rule.

[0055] Curve N4 is the curve between curve N1, which includes temperature target point T1, and curve N2, which includes temperature target point T2, in the nonlinear step curve L. Curve N4 is a linear curve. The fan speed at the starting point of curve N4 is 4000, corresponding to the upper temperature limit of 50 degrees Celsius on curve N1, and the fan speed at the end point of curve N4 is 6000, corresponding to the lower temperature limit of 60 degrees Celsius on curve N2. The fan speeds corresponding to the key component temperatures on curve N4 are arranged according to a linear rule, that is, the corresponding fan speeds are obtained on curve N4 based on the key component temperatures. Similarly, as shown in the figure, the starting point of curve N5 is 8000, corresponding to the upper temperature limit of 70 degrees Celsius on curve N2, and the end point of curve N5 is 13000, corresponding to the lower temperature limit of 80 degrees Celsius on curve N3. The fan speeds corresponding to the key component temperatures on the broken line curve N5 are arranged according to a linear rule.

[0056] Based on the real-time temperature of key components, the corresponding second fan speed is obtained according to the PID speed control algorithm, especially the fan speed corresponding to each curve formed according to the set different temperature target points. By comparing the obtained first fan speed and second fan speed, the fan speed value is adjusted according to the fan speed with the higher speed, thereby achieving the setting of different temperature target points through the PID speed control algorithm, and further obtaining the second fan speed corresponding to the temperature of the key component according to the different temperature target points, thereby avoiding the problems in the prior art when the target point is set too high, too low or in the middle due to setting a single temperature target point, and can meet different heat dissipation requirements.

[0057] Further taking into account the requirements of the real-time load of the target device for the fan speed, in an optional embodiment, the fan speed regulation method also includes: obtaining the load of the target device in real time, and before adjusting the fan speed with the higher value of the first fan speed and the second fan speed, the fan speed regulation method also includes: obtaining a third fan speed corresponding to the load according to a preset load and speed configuration table, and the load and speed configuration table includes different loads and fan speeds corresponding to each load one by one; adjusting the fan speed with the higher value of the first fan speed and the second fan speed further includes: adjusting the fan speed with the higher value of the first fan speed, the second fan speed and the third fan speed.

[0058] In this embodiment, by adding a third fan speed corresponding to the real-time load of the target device, the fan speed is further adjusted according to the higher value of the first fan speed, the second fan speed and the third fan speed, thereby achieving the selection of an appropriate fan speed according to the real-time ambient temperature, key device temperature and real-time load of the target device, further improving the accuracy of the fan speed setting.

[0059] Corresponding to the fan speed regulation method provided in the above embodiment, an embodiment of the present application also provides a fan for implementing the above fan speed regulation method, including a controller, wherein the controller is configured to: obtain the ambient temperature and the temperature of the key component in real time according to the temperature sensor set on the target device; obtain the first fan speed corresponding to the ambient temperature according to a preset temperature and speed configuration table, and the temperature and speed configuration table includes different temperatures and fan speeds corresponding to each temperature; obtain the second fan speed corresponding to the key component temperature according to a preset PID speed regulation algorithm, and the PID speed regulation algorithm includes at least two temperature target points; adjust the fan speed with the higher value of the first fan speed and the second fan speed.

[0060] The fan of this embodiment obtains the fan speed corresponding to the temperature of the key component through a PID speed control algorithm including at least two temperature target points, and adjusts the fan speed according to a first fan speed corresponding to the ambient temperature and a second fan speed obtained by the PID speed control algorithm corresponding to the temperature of the key component.
