[0032] See also Figure 1 and Figure 2 , Figure 1 A schematic diagram of a flow chart of a fan intelligent temperature control method provided by an embodiment of the present invention. Figure 2Schematic diagram of application scenario of the intelligent temperature control method for a fan provided in an embodiment of the present invention; the intelligent temperature control method for a fan is applied to a controller 10, the control output end of the controller 10 is connected to the control input end of a fan main control circuit 20, and the power output end 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, and the temperature sensor 30 is arranged on the outlet side of the fan, then the temperature sensor can detect the temperature on the outlet side of the fan, obtain a corresponding temperature detection signal and send it to the controller 10, the controller 10 samples the temperature detection signal to obtain a corresponding sampled temperature value. The controller 10 is a controller installed in the terminal device to control the speed of the fan configured in the terminal device. The controller 10 can be an electronic device with information processing and command receiving and sending functions, such as a fan power supply control chip, a Soc chip for computer motherboard control, etc.; the fan main control circuit 20 is a control circuit for receiving command signals from the controller 10 and adjusting the output duty cycle accordingly; the terminal device can be a desktop computer, a laptop computer, a server host, etc. In addition to the controller 10, the fan main control circuit 20 and the fan 11, the terminal device can also be equipped with a CPU chip, a non-volatile memory (such as a storage hard disk), a volatile memory (such as a memory stick), a graphics card (graphics processor), a power supply, etc. The fan 11 can be a fan dedicated to dissipating heat for the controller 10, and the fan 11 is set close to one side of the device to be dissipated; the fan 11 can also be a fan dedicated to dissipating heat for 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 instruction is received, a corresponding drive control instruction is sent to the fan main control circuit according to a preset initial rotation speed, so that the fan main control circuit drives the fan to work according to the drive instruction.

[0034] If a start command is received, a corresponding drive control command is issued 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. The user can input a start command to the controller (such as the user pressing the power on button), and the controller controls the fan to work after receiving the start command. Specifically, the controller can issue a corresponding drive control command to the fan main control circuit according to the pre-configured initial speed, and the fan main control circuit outputs a pulse signal to the fan according to the drive control command. The duty cycle of the pulse signal output by the fan main control circuit corresponds to the command parameter in the drive control command. At this time, the speed of the fan is equal to the initial speed.

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

[0036] According to the preset sampling parameters, periodic sampling is performed to obtain a temperature sequence corresponding to a 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 a sampling period. Further, the controller can perform periodic sampling on the temperature signal monitored by the temperature sensor, and a set of temperature sequences obtained by sampling corresponds to a sampling period, and step S120 is repeated once after each sampling period. The sampling parameter can be configured with a cycle duration. For example, if the cycle duration in the sampling parameter is 3 seconds, sampling is performed every 3 seconds and a set of temperature sequences is obtained. The sampling parameter is also configured with a sampling frequency, which is the frequency information for sampling the temperature value. If the sampling frequency is set to 10Hz, the temperature signal is sampled 10 times every 1 second to obtain 10 sampled temperature values, and 30 sampled temperature values ​​can be obtained in a sampling period with a cycle duration of 3 seconds; the multiple sampled temperature values ​​obtained within a sampling period are combined into a set of temperature sequences corresponding to the sampling period, and the sampled temperature values ​​in the temperature sequence are arranged in order according to the sampling time of the numerical value.

[0037] S130. Obtaining a target speed corresponding to the end temperature value of the temperature sequence according to a preset speed configuration table.

[0038] The target speed corresponding to the termination temperature value of the temperature sequence is obtained according to the preset speed configuration table. Specifically, the termination temperature value of the temperature sequence can be obtained, and the speed corresponding to the termination temperature value can be obtained from the speed configuration table according to the termination temperature value as the target speed. The speed configuration table contains multiple speed configuration gears, each speed configuration gear corresponds to a temperature value interval, and the termination temperature value can be matched with the temperature value interval of each speed configuration gear in the speed configuration table, so as to obtain the speed set by the speed configuration gear corresponding to the matching temperature value interval as the target speed.

[0039] S140: Determine whether the temperature sequence satisfies a preset speed change condition.

[0040] Determine whether the temperature sequence satisfies a preset speed change condition. The sampled temperature value contained in the temperature sequence may be obtained, and it may be determined whether the speed change condition is met. If the speed change condition is met, the fan speed is controlled to be variable speed in the next sampling period; if the speed change condition is not met, the fan speed is controlled to be constant 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; and determining whether the absolute value of the temperature difference is greater than the temperature threshold set in the speed change condition to determine whether the speed change condition is met.

[0042] Specifically, the starting temperature value and the ending temperature value 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 temperature value and the ending temperature value is calculated and the absolute value is taken to obtain the absolute value of the temperature difference; it is determined whether the absolute value of the temperature difference is greater than the temperature threshold set in the speed change condition. If the absolute value of the temperature difference is greater than the temperature threshold, it indicates that the temperature changes greatly during the current sampling period, and the speed of the fan needs to be controlled at a variable speed, and it is determined that the speed change condition is met; if the absolute value of the temperature difference is not greater than the temperature threshold, it indicates that the temperature changes little during the current sampling period, and it is determined that the speed change condition is not met.

[0043] S150: If the temperature sequence does not satisfy the speed change condition, a corresponding drive control instruction is issued 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 instruction is issued to the fan main control circuit according to the target speed. If the speed change condition is not met, a corresponding drive control instruction is directly issued to the fan main control circuit according to the target speed. The drive control instruction issued at this time can drive the fan to operate at the target speed, and the fan will maintain the target speed for operation in the next sampling period.

[0045] After executing step S150, the process can return to step S120 until the input shutdown command is received to terminate the process of controlling the fan speed. Returning to step S120, the temperature sequence corresponding to the next sampling period can be collected during the fan running at the target speed and the above steps can be executed cyclically.

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

[0047] If the temperature sequence meets the speed change condition, the speed change coefficient corresponding to the temperature sequence is obtained according to the preset speed change strategy. If the temperature sequence meets the speed change condition, the corresponding speed change coefficient can be obtained according to the speed change strategy, and the obtained speed change coefficient corresponds to the temperature sequence. The speed change coefficient can be used to control the speed of the fan in the next sampling period.

[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 front segment slope value corresponding to the front segment in the segmented temperature sequence and the rear segment slope value corresponding to the rear segment in the temperature sequence; determining the speed change coefficient corresponding to the current fan speed, the temperature sequence, the front segment slope value and the rear segment slope value 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 change strategy. The number of segmentation values ​​can be set in the segmentation rules. For example, if the number of segmentation values ​​set in the segmentation rules is 8, the first 8 sampled temperature values ​​in the temperature sequence can be obtained as the first segment of the temperature sequence; the last 8 sampled temperature values ​​in the temperature sequence can be obtained as the second segment of the temperature sequence. Further, the first segment slope value of the sampled temperature values ​​contained in the first segment of the temperature sequence is calculated. The first segment slope value is the difference between the starting value and the ending value of the first segment of the temperature sequence divided by the horizontal axis span, where the horizontal axis span is also the time span covered by the first segment of the temperature sequence. According to the above method, the second segment slope value of the second segment of the temperature sequence can be calculated accordingly.

[0050] The speed change coefficient corresponding to the current fan speed, temperature sequence, front-end slope value and rear-end slope value is determined according to the coefficient determination rule set in the speed change strategy.

[0051] In one embodiment, the speed change coefficient corresponding to the current fan speed, the temperature sequence, the front slope value and the rear slope value is determined according to the coefficient determination rule in the speed change strategy, including: obtaining the temperature difference between the end temperature value and the start temperature value of the temperature sequence; calculating the current fan speed, the front slope value and the rear slope value according to the coefficient calculation formula in the coefficient determination rule to obtain the corresponding coefficient value; obtaining the numerical sign of the temperature difference and combining it with the coefficient value to obtain the corresponding speed change coefficient.

[0052] Specifically, the temperature difference between the end temperature value and the start temperature value of the temperature sequence can be obtained. The temperature difference is a value greater than zero or less than zero. The current fan speed, the front slope value and the back slope value are further calculated according to the coefficient calculation formula to obtain the corresponding coefficient value. The coefficient calculation formula can be expressed by formula (1):

[0053]

[0054] Among them, S0 is the initial speed, S is the current fan speed, t0 is the cycle length set in the sampling parameters, p2 is the slope value of the latter section, p1 is the slope value of the former section, 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, and 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, issuing a corresponding drive control instruction to the fan main control circuit according to the target speed and the speed change coefficient.

[0057] The corresponding drive control instruction is sent to the fan main control circuit according to the target speed and the speed coefficient. The controller adjusts the fan according to the target speed and further controls the fan according to the speed 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 according to the target speed and the speed change coefficient; and sending drive control instructions 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 control speed at each time point in the next sampling period can be determined according to the target speed and the speed change coefficient. The fan control speed can be set to v i =v0+t i ×g; where v i is the fan speed control at the i-th time point, t i is the time parameter corresponding to the i-th time point of the next sampling cycle, g is the speed coefficient, and v0 is the target speed. For example, if the time parameter corresponding to the starting time point (the first time point) in the next sampling cycle is 0, then the fan control speed at this time point is also the target speed. If the interval between a certain time point and the starting time point in the next sampling cycle is 2 seconds, then the corresponding time parameter is 2, and the fan control speed at this time point is calculated to be v0+2×g.

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

[0061] After determining the fan speed control at each time point, when the corresponding time point is reached, the corresponding drive control instruction is sent to the fan main control circuit according to the fan speed control at that time point, so as to achieve variable speed adjustment of the fan. After executing step S170, the process can return to step S120 until the input shutdown instruction is received to terminate the process of fan speed control. Returning to step S120, the temperature sequence corresponding to the next sampling period can be collected during the operation of the fan at the target speed and the above steps can be executed cyclically.

[0062] Since the speed of the fan to be regulated in the next sampling period is determined in advance according to the temperature sequence of the previous sampling period, the hysteresis existing in the regulation of the fan speed in the prior art is avoided, the heat dissipation temperature control of the device is achieved and the heat dissipation effect of the fan is greatly improved.

[0063] In the fan intelligent temperature control method provided in the embodiment of the present invention, the method includes: upon receiving the start-up instruction, a drive control instruction is issued to the fan main control circuit according to the initial speed, periodic sampling is performed to obtain the temperature sequence on the fan outlet side and the corresponding target speed is obtained according to the speed configuration table, and it is determined whether the temperature sequence meets the speed change condition. If not, a corresponding drive control instruction is issued according to the target speed; if it meets the condition, a speed change coefficient corresponding to the temperature sequence is obtained according to the speed change strategy, and a corresponding drive control instruction is issued to the fan main control circuit according to the target speed and the speed change coefficient. Through the above 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 of the fan speed adjustment process, realizing heat dissipation and temperature control of the device, and greatly improving the heat dissipation effect of the fan.

[0064] The embodiment of the present invention also provides a fan intelligent temperature control device, which can be configured in a controller 10, wherein the control output end of the controller 10 is connected to the control input end of the fan main control circuit 20, and the power output end of the fan main 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 for communication, and the temperature sensor 30 is arranged on the outlet side of the fan, so that the temperature sensor can detect the temperature on the outlet side of the fan.

[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 a 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 a sampling period.
