Technical Field

[0001] This invention relates to the field of intelligent control technology, and in particular to a method, device, equipment and medium for intelligent temperature control of a fan. Background Technology

[0002] Cooling fans are widely used in desktop computers, laptops, server hosts, and other devices to dissipate heat from heat-generating components, ensuring their normal operation. Existing fan speed control typically adjusts based on real-time temperature readings or the heat dissipation of the components, thus matching the fan speed to the current temperature or heat dissipation. However, this method cannot adapt the fan speed to changes in temperature or heat dissipation, and there is a delay in both the output of control commands and the adjustment of the fan speed. Therefore, the fan speed adjustment inevitably exhibits a certain lag, failing to effectively control the temperature and heat dissipation of the components, resulting in poor cooling performance. Thus, existing methods for controlling cooling fan speed suffer from the problem of speed adjustment lag. Summary of the Invention

[0032] Please see Figure 1 and Figure 2 , Figure 1 This is a flowchart illustrating the intelligent temperature control method for fans provided in an embodiment of the present invention. Figure 2This is a schematic diagram illustrating an application scenario of the intelligent temperature control method for a fan provided in this embodiment of the invention. The intelligent temperature control method is applied in a controller 10. The control output terminal of the controller 10 is connected to the control input terminal of the main fan control circuit 20, and the power output terminal of the main fan control circuit 20 is electrically connected to the power supply port of the fan 11. The controller 10 is also connected to a temperature sensor 30, which is located on the fan's outlet side. The temperature sensor can detect the temperature on the fan's outlet side, obtain a corresponding temperature detection signal, and send it to the controller 10. The controller 10 samples the temperature detection signal to obtain the corresponding sampled temperature value. Controller 10 is a controller installed within the terminal device to control the speed of the fan configured within the terminal device. Controller 10 can be an electronic device with information processing and command transmission / reception functions, such as a fan power supply control chip or a SoC chip used for computer motherboard control. The fan main control circuit 20 is a control circuit used to receive command signals from controller 10 and adjust the output duty cycle accordingly. The terminal device can be a desktop computer, laptop computer, server host, etc. In addition to controller 10, fan main control circuit 20, and fan 11, the terminal device can also be equipped with a CPU chip, non-volatile memory (such as a hard disk drive), volatile memory (such as RAM), graphics card (graphics processor), power supply, etc. Fan 11 can be a fan specifically for cooling controller 10, and is positioned close to the side of the device to be cooled; fan 11 can also be a fan specifically for cooling other electronic devices (such as CPU chips, non-volatile memory, graphics cards, or power supplies). Figure 1 As shown, the method includes steps S110 to S170.

[0033] S110. If a start command is received, a corresponding drive control command is sent to the fan main control circuit according to the preset initial speed, so that the fan main control circuit drives the fan to work according to the drive command.

[0034] Upon receiving a start command, the controller sends a corresponding drive control command to the fan main control circuit based on a preset initial speed, causing the fan main control circuit to drive the fan to operate according to the drive command. The user can input a start command into the controller (e.g., by pressing the power button), and the controller, upon receiving the start command, will control the fan to operate. Specifically, the controller can send a corresponding drive control command to the fan main control circuit based on a pre-configured initial speed. The fan main control circuit then outputs a pulse signal to the fan according to the drive control command, and the duty cycle of the output pulse signal corresponds to the command parameters in the drive control command. At this time, the fan speed is equal to the initial speed.

[0035] S120. Perform periodic sampling according to preset sampling parameters to obtain the temperature sequence corresponding to one sampling period monitored by the temperature sensor.

[0036] Periodic sampling is performed according to preset sampling parameters to obtain a temperature sequence corresponding to one sampling period monitored by the temperature sensor. The temperature sequence includes multiple sampled temperature values ​​obtained within one sampling period at the sampling frequency specified in the sampling parameters. Further, the controller can periodically sample the temperature signal monitored by the temperature sensor, and a set of sampled temperature sequences corresponds to one sampling period. Step S120 is repeated once after each sampling period. The sampling parameters can be configured with a period duration. For example, if the period duration in the sampling parameters is 3 seconds, then sampling is performed every 3 seconds to obtain a set of temperature sequences. The sampling parameters also configure a sampling frequency, which is the frequency information for sampling temperature values. For example, if the sampling frequency is set to 10Hz, then the temperature signal is sampled 10 times per second to obtain 10 sampled temperature values. Within a sampling period with a period duration of 3 seconds, 30 sampled temperature values ​​can be obtained. The multiple sampled temperature values ​​obtained within one sampling period are combined to form a temperature sequence corresponding to that sampling period. The sampled temperature values ​​in the temperature sequence are arranged sequentially according to the sampling time of the values.

[0037] S130. Obtain the target rotational speed corresponding to the termination temperature value of the temperature sequence according to the preset rotational speed configuration table.

[0038] The target speed is obtained according to a preset speed configuration table, corresponding to the ending temperature value of the temperature sequence. Specifically, the ending temperature value of the temperature sequence can be obtained, and the speed corresponding to the ending temperature value can be obtained from the speed configuration table as the target speed. The speed configuration table contains multiple speed configuration levels, each corresponding to a temperature range. The ending temperature value can be matched with the temperature range of each speed configuration level in the speed configuration table to obtain the speed set by the speed configuration level corresponding to the matching temperature range as the target speed.

[0039] S140. Determine whether the temperature sequence meets the preset speed change conditions.

[0040] Determine whether the temperature sequence meets the preset speed change conditions. The sampled temperature values ​​contained in the temperature sequence can be obtained, and it can be determined whether the speed change conditions are met. If the speed change conditions are met, the fan speed is controlled by speed change in the next sampling period; if the speed change conditions are not met, the fan speed is controlled by constant speed in the next sampling period.

[0041] In one embodiment, step S140 includes the following steps: obtaining the absolute value of the temperature difference between the starting temperature value and the ending temperature value of the temperature sequence; determining whether the absolute value of the temperature difference is greater than the temperature threshold set in the speed change condition, so as to determine whether the speed change condition is met.

[0042] Specifically, the starting and ending temperature values ​​in the temperature sequence can be obtained. The starting temperature value is the first sampled temperature value in the temperature sequence, and the ending temperature value is the last sampled temperature value in the temperature sequence. The difference between the starting and ending temperature values ​​is calculated and its absolute value is taken to obtain the absolute temperature difference. It is then determined whether the absolute temperature difference is greater than the temperature threshold set in the speed change condition. If the absolute temperature difference is greater than the temperature threshold, it indicates that the temperature change is large in the current sampling period, and the fan speed needs to be controlled by speed change, thus the speed change condition is met. If the absolute temperature difference is not greater than the temperature threshold, it indicates that the temperature change is small in the current sampling period, and the speed change condition is not met.

[0043] S150. If the temperature sequence does not meet the speed change condition, a corresponding drive control command is sent to the fan main control circuit according to the target speed.

[0044] If the temperature sequence does not meet the speed change condition, a corresponding drive control command is sent to the fan main control circuit according to the target speed. If the speed change condition is not met, a corresponding drive control command is sent directly to the fan main control circuit according to the target speed. The drive control command sent at this time can drive the fan to operate at the target speed, and the fan will maintain the target speed during the next sampling period.

[0045] After executing step S150, the process can return to step S120 until a shutdown command is received, at which point the fan speed control process terminates. Returning to step S120 allows the temperature sequence corresponding to the next sampling period to be collected while the fan is running at the target speed, and the above steps are executed repeatedly.

[0046] S160. If the temperature sequence satisfies the speed change condition, obtain the speed change coefficient corresponding to the temperature sequence according to the preset speed change strategy.

[0047] If the temperature sequence meets the speed change condition, a speed change coefficient corresponding to the temperature sequence is obtained according to a preset speed change strategy. The obtained speed change coefficient corresponds to the temperature sequence. The fan speed can then be controlled in the next sampling period using the speed change coefficient.

[0048] In one embodiment, step S160 includes the following steps: segmenting the temperature sequence according to the segmentation rules in the speed change strategy; obtaining the slope value of the first segment and the slope value of the second segment in the segmented temperature sequence; and determining the speed change coefficient corresponding to the current fan speed, the temperature sequence, the slope value of the first segment, and the slope value of the second segment according to the coefficient determination rules in the speed change strategy.

[0049] Specifically, the temperature sequence can be segmented according to the segmentation rules in the speed-changing strategy. The segmentation rules can specify the number of segment values. For example, if the number of segment values ​​is set to 8, the first 8 sampled temperature values ​​in the temperature sequence can be obtained as the first segment, and the last 8 sampled temperature values ​​can be obtained as the second segment. Further, the slope value of the first segment is calculated. The slope value is the difference between the starting and ending values ​​of the first segment divided by the horizontal axis span, where the horizontal axis span is the time span covered by the first segment. Based on the above method, the slope value of the second segment can be calculated accordingly.

[0050] The speed change coefficients corresponding to the current fan speed, temperature sequence, initial slope value, and subsequent slope value are determined according to the coefficient determination rules set in the speed change strategy.

[0051] In one embodiment, determining the speed change coefficient corresponding to the current fan speed, the temperature sequence, the initial slope value, and the subsequent slope value according to the coefficient determination rule in the speed change strategy includes: obtaining the temperature difference between the ending temperature value and the starting temperature value of the temperature sequence; calculating the current fan speed, the initial slope value, and the subsequent slope value according to the coefficient calculation formula in the coefficient determination rule to obtain the corresponding coefficient value; and combining the numerical sign of the temperature difference value with the coefficient value to obtain the corresponding speed change coefficient.

[0052] Specifically, the temperature difference between the ending temperature and the starting temperature of the temperature sequence can be obtained. This temperature difference is a value greater than or less than zero. Further, the current fan speed, the initial slope value, and the subsequent slope value are calculated according to the coefficient calculation formula to obtain the corresponding coefficient values. The coefficient calculation formula can be expressed by formula (1):

[0053]

[0054] Where S0 is the initial speed, S is the current fan speed, t0 is the period duration set in the sampling parameters, p2 is the slope value of the later stage, p1 is the slope value of the earlier stage, and r is the calculated coefficient value. The calculated coefficient value is a positive value.

[0055] Furthermore, the numerical sign of the temperature difference can be obtained and combined with the coefficient value. The coefficient value can be rounded and combined with the numerical sign of the temperature difference to obtain the speed change coefficient. Then the numerical sign of the temperature difference ("+" or "-") is the same as the numerical sign of the speed change coefficient.

[0056] S170. Based on the target speed and the speed change coefficient, a corresponding drive control command is sent to the fan main control circuit.

[0057] Based on the target speed and the speed change coefficient, the controller sends a corresponding drive control command to the fan main control circuit. Then, the controller adjusts the fan according to the target speed and further performs speed control on the fan based on the speed change coefficient.

[0058] In one embodiment, step S170 includes the following steps: determining the fan control speed at each time point in the next sampling period based on the target speed and the speed change coefficient; and sending drive control commands corresponding to each time point to the fan main control circuit according to the fan control speed at each time point.

[0059] Specifically, the fan speed control can be determined at each time point within the next sampling period based on the target speed and the speed change coefficient. The fan speed control can be set to v. i =v0+t i ×g; where v i To adjust the fan speed at the i-th time point, t i Let v0 be the time parameter corresponding to the i-th time point in the next sampling period, g be the speed change coefficient, and v0 be the target speed. For example, if the time parameter corresponding to the starting time point (the first time point) in the next sampling period is 0, then the fan speed at that time point is also the target speed. If the interval between a certain time point in the next sampling period and the starting time point is 2 seconds, then the corresponding time parameter is 2, and the fan speed at that time point is calculated as v0 + 2 × g.

[0060] Determine whether the fan speed control at each time point is less than the minimum speed value or greater than the maximum speed value. If the calculated fan speed control at a certain time point is less than the minimum speed value, then the minimum speed value is redefined as the fan speed control at that time point; if the calculated fan speed control at a certain time point is greater than the maximum speed value, then the maximum speed value is redefined as the fan speed control at that time point.

[0061] After determining the fan speed control at each time point, upon reaching the corresponding time point, a corresponding drive control command is sent to the fan main control circuit based on the fan speed control at that time point, thereby realizing the variable speed adjustment of the fan. After executing step S170, the process can return to step S120 until the input shutdown command is received, at which point the process of controlling the fan speed terminates. Returning to step S120 allows the temperature sequence corresponding to the next sampling period to be collected while the fan is running at the target speed, and the above steps are executed cyclically.

[0062] By determining the fan speed for the next sampling period in advance based on the temperature sequence of the previous sampling period, the lag in fan speed control in existing technologies is avoided, thereby achieving heat dissipation and temperature control of the device and significantly improving the fan's heat dissipation effect.

[0063] In the intelligent temperature control method for fans provided in this embodiment of the invention, the method includes: upon receiving a start command, issuing a drive control command to the fan main control circuit based on the initial speed; periodically sampling to obtain the temperature sequence at the fan outlet and obtaining the corresponding target speed according to the speed configuration table; determining whether the temperature sequence meets the speed change conditions; if not, issuing a corresponding drive control command based on the target speed; if so, obtaining the speed change coefficient corresponding to the temperature sequence according to the speed change strategy; and issuing a corresponding drive control command to the fan main control circuit based on the target speed and the speed change coefficient. Through this method, the temperature change trend can be obtained based on the temperature sequence corresponding to the sampling period, and the fan speed can be adjusted based on the temperature change trend, thereby avoiding the lag in the fan speed adjustment process, achieving heat dissipation and temperature control of the device, and significantly improving the fan's heat dissipation effect.

[0064] This invention also provides a smart fan temperature control device, which can be configured in a controller 10. The control output terminal of the controller 10 is connected to the control input terminal of the fan main control circuit 20, and the power output terminal of the fan main control circuit 20 is electrically connected to the power supply port of the fan 11. The controller 10 is also communicatively connected to a temperature sensor 30, which is located on the fan outlet side, allowing the temperature sensor to detect the temperature at the fan outlet side. This smart fan temperature control device is used to execute any embodiment of the aforementioned smart fan temperature control method. For details, please refer to...

[0067] The temperature sequence acquisition unit 120 is used to perform periodic sampling according to preset sampling parameters to obtain a temperature sequence corresponding to one sampling period monitored by the temperature sensor; the temperature sequence includes multiple sampled temperature values ​​obtained by sampling at the sampling frequency in the sampling parameters within one sampling period.

[0070] The second instruction sending unit 150 is used to send a corresponding drive control instruction to the fan main control circuit according to the target speed if the temperature sequence does not meet the speed change condition.

[0071] The speed change coefficient acquisition unit 160 is used to acquire the speed change coefficient corresponding to the temperature sequence according to a preset speed change strategy if the temperature sequence meets the speed change condition.
