[0026] See also Figure 1 and Figure 2 , Figure 1A schematic diagram of a flow chart of a fan gear intelligent matching and adjustment method provided in an embodiment of the present invention, Figure 2 Schematic diagram of the application scenario of the fan gear intelligent matching and adjustment method provided in the embodiment of the present invention; the fan gear intelligent matching and adjustment method is applied to the fan main control circuit 10, the control input end of the fan main control circuit 10 is connected to the controller 20, the power output end of the fan main control circuit 10 is electrically connected to the power supply port of the fan 11, the fan main control circuit 10 is arranged on the air inlet side of the fan 11, and the fan main control circuit 10 is also provided with a temperature sensing device, through which an analog signal can be obtained and converted into a digital signal accordingly, so as to obtain the current air inlet temperature. The fan main control circuit 10 is a control circuit for receiving a command signal from the controller 20 and adjusting the output duty cycle accordingly, such as a PLC (Programmable Logic Controller) circuit board carrying an MCU chip, and the controller 20 is a control device for outputting conditional instructions to the fan main control circuit 10, such as a Soc chip for computer motherboard control. Figure 1 As shown, the method includes steps S110 to S140.

[0027] S110: If a speed adjustment instruction is received from the controller, a speed difference between the speed adjustment instruction and the current fan speed is obtained.

[0028] If a speed adjustment instruction is received from the controller, the speed difference between the speed adjustment instruction and the current fan speed is obtained. The fan main control circuit receives the speed adjustment instruction from the controller, and the speed adjustment instruction includes a target fan speed, which is the final speed that the fan currently needs to adjust. The target fan speed in the speed adjustment instruction can be obtained, and the speed difference between the target fan speed and the current fan speed can be calculated.

[0029] S120. Obtaining an adjustment rate corresponding to the rotational speed difference and the current inlet air temperature according to a preset adjustment rate strategy.

[0030] The adjustment rate corresponding to the speed difference and the current inlet air temperature is obtained according to the preset adjustment rate strategy. Further, the corresponding adjustment rate can be obtained according to the adjustment rate strategy, and the obtained adjustment rate corresponds to the speed socket and the current inlet air temperature.

[0031] In one embodiment, step S120 includes the following steps: calculating the rate coefficient corresponding to the speed difference and the current inlet air temperature according to the rate coefficient calculation formula in the rate adjustment strategy; determining whether the rate coefficient is within the adjustment rate interval in the rate adjustment strategy; if the rate coefficient is within the adjustment rate interval, determining the rate coefficient as the corresponding adjustment rate.

[0032] Specifically, the rate coefficient corresponding to the speed difference and the current inlet air temperature can be calculated according to the rate calculation formula in the rate adjustment strategy. The rate coefficient calculation formula can be expressed by formula (1):

[0033]

[0034] S is the calculated speed coefficient, C is the speed difference, T r is the current inlet air temperature, and T0 is the room temperature (25℃).

[0035] Further, it is determined whether the rate coefficient is within the adjustment rate interval in the adjustment rate strategy, for example, the adjustment rate interval may be set to [200, 800]. If the rate coefficient is within the adjustment rate interval, the rate coefficient is determined to be the corresponding adjustment coefficient.

[0036] In one embodiment, step S120 also includes the following steps: if the rate coefficient is not within the adjustment rate interval, determine whether the rate coefficient is less than the lower limit value of the adjustment rate interval; if the rate coefficient is less than the lower limit value of the adjustment rate interval, determine the lower limit value as the corresponding adjustment rate; if the rate coefficient is not less than the lower limit value of the adjustment rate interval, determine the upper limit value of the adjustment rate interval as the corresponding adjustment rate.

[0037] If the rate coefficient is not within the adjustment rate interval, determine whether the rate coefficient is less than the lower limit of the adjustment rate interval; if it is less than the lower limit of the adjustment rate interval, the lower limit is the corresponding adjustment rate; if it is not less than the lower limit of the adjustment rate interval, it indicates that the rate coefficient is greater than the upper limit of the adjustment rate interval, and the upper limit of the adjustment rate interval can be determined as the corresponding adjustment rate.

[0038] S130. Acquire a target speed gear corresponding to the adjustment speed according to a preset gear matching strategy.

[0039] The target speed gear corresponding to the adjustment speed is obtained according to the preset gear matching strategy. Further, the target speed gear corresponding to the adjustment speed is obtained according to the gear matching strategy, wherein the gear matching strategy includes multiple speed gears, and each speed gear corresponds to a speed range.

[0040] In one embodiment, step S130 includes the following steps: matching the adjustment rate with the rate range of each rate gear in the gear matching strategy; and obtaining a rate gear whose rate range matches the adjustment rate as a target rate gear.

[0041] Specifically, the adjustment rate can be matched with the rate range of each rate gear in the gear matching strategy. If the adjustment rate is within the corresponding rate range, it means that the rate gear corresponding to the rate range matches the adjustment rate. Through this method, the rate gear whose rate range matches the adjustment rate can be obtained as the target rate gear. Then, there is only one rate gear that matches the adjustment rate.

[0042] S140, controlling the duty cycle output to the fan according to the target speed gear and the speed adjustment instruction, so as to adjust the speed of the fan correspondingly according to the target speed gear.

[0043] The duty cycle output to the fan is controlled according to the target speed gear and the speed adjustment instruction, so as to adjust the speed of the fan accordingly according to the target speed gear. Further, the duty cycle output is controlled according to the target speed gear and the target fan speed in the speed adjustment instruction, and the power of the fan can be adjusted accordingly by the size of the output duty cycle. The power of the fan is positively correlated with the speed of the fan, that is, the speed of the fan can be adjusted.

[0044] In one embodiment, step S140 includes the following steps: determining a corresponding target duty cycle according to the target fan speed in the speed adjustment instruction; determining a corresponding adjustment rate according to the target speed gear; and adjusting the duty cycle output to the fan to the target duty cycle according to the adjustment rate to correspondingly adjust the speed of the fan.

[0045] Specifically, the target duty cycle corresponding to the target fan speed can be determined. When the voltage is constant, there is a mapping relationship between the speed and the duty cycle. A certain speed is mapped to a corresponding duty cycle. The target duty cycle corresponding to the target fan speed can be obtained based on the mapping relationship between the speed and the duty cycle.

[0046] The corresponding adjustment rate is determined according to the target speed gear. Different target speed gears correspond to different adjustment rates. The adjustment rate is also the step rate of each duty cycle adjustment. For example, if the adjustment interval is 0.02s, the duty cycle output to the fan is adjusted once every 0.02 seconds, and the difference between the two adjacent duty cycles is the adjustment rate.

[0047] According to the duty cycle of the adjustment output to the fan corresponding to the adjustment rate, the current output duty cycle is gradually adjusted to the target duty cycle based on the adjustment rate, thereby adjusting the fan speed to the target fan speed in the speed adjustment instruction.

[0048] In the fan gear intelligent matching and adjustment method provided in the embodiment of the present invention, the method includes: if a speed adjustment instruction is received from the controller, obtaining the speed difference between the speed adjustment instruction and the current fan speed; obtaining the adjustment rate corresponding to the speed difference and the current inlet air temperature according to a preset adjustment rate strategy; obtaining the target speed gear corresponding to the adjustment rate according to a preset gear matching strategy; controlling the duty cycle output to the fan according to the target speed gear and the speed adjustment instruction, so as to adjust the fan speed according to the target speed gear. Through the above method, the target speed gear can be matched according to the current inlet air temperature and the speed difference, and the duty cycle output to the fan can be controlled according to the target speed gear and the speed adjustment instruction to achieve the adjustment of the fan speed, so as to avoid the fan speed being adjusted too fast and affecting the stability of the fan operation.

[0049] The embodiment of the present invention further provides a fan gear intelligent matching adjustment device, which can be configured in the fan main control circuit 10, the control input end of the fan main control circuit 10 is connected to the controller 20, and the power output end of the fan main control circuit 10 is electrically connected to the power supply port of the fan 11.

[0052] The regulation rate acquisition unit 120 is used to acquire the regulation rate corresponding to the rotation speed difference and the current inlet air temperature according to a preset regulation rate strategy.

[0055] The target speed gear acquisition unit 130 is used to acquire the target speed gear corresponding to the adjustment speed according to a preset gear matching strategy.

[0056] The duty cycle adjustment unit 140 is used to control the duty cycle output to the fan according to the target speed gear and the speed adjustment instruction, so as to adjust the speed of the fan correspondingly according to the target speed gear.
