[0027] The exemplary embodiments will be described in detail below with reference to the accompanying drawings. In the following description, the same numbers refer to the same elements throughout the drawings. The implementation described in the following exemplary embodiments does not represent all implementations consistent with the present disclosure. Instead, they only represent examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0028] The implementation described in the following exemplary embodiments does not represent all implementations consistent with the present disclosure. Instead, they only represent examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0029] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the corresponding data protection regulations and policies of the country where the device is located, and with the authorization given by the owner of the corresponding device.

[0030] In the related art, the inductance parameter of the fan is usually determined according to the hardware parameter condition of the fan, and is a fixed value after leaving the factory. However, the inductance is strongly dependent on current and temperature, and setting a fixed inductance value cannot meet the actual use requirements of the fan.

[0031] To solve the above technical problems, the present disclosure provides a fan parameter determination method, a control method, a device, equipment, a medium and a product to improve the rationality of fan parameter determination and further improve the stability of the fan running at different speeds.

[0032] Figure 1 A flowchart of a fan parameter determination method according to an exemplary embodiment is shown in FIG. 1. As shown in FIG. 1, the method can be used in an electronic device, and the method can include the following steps: Figure 1 In step S101, for any to-be-tested speed value, a boundary inductance value corresponding to the to-be-tested speed value is determined, wherein when the fan runs at the to-be-tested speed value and a candidate inductance value as control parameters, the speed fluctuation of the fan meets a preset fluctuation range, the to-be-tested speed value is located in a rated speed range of the fan, and the candidate inductance value is located in an inductance range corresponding to the boundary inductance value.

[0033] In the present embodiment, a plurality of to-be-tested speed values can be determined from the rated speed range of the fan, and for any to-be-tested speed value, a boundary inductance value corresponding to the to-be-tested speed value can be determined.

[0034] In the present embodiment, the boundary inductance value can include a first inductance value and a second inductance value, the first inductance value and the second inductance value form an inductance range, and the inductance values in the inductance range corresponding to the boundary inductance value are referred to as candidate inductance values.​

[0035] In some embodiments, the method of the present disclosure can further comprise the following steps of determining the to-be-tested rotating speed value: In the rated rotating speed range, every preset rotating speed value, a to-be-tested rotating speed value is determined.

[0036] For example, the lowest rotating speed or the highest rotating speed in the rated rotating speed range can be taken as the starting point, and every 100 rotating speed, a to-be-tested rotating speed value is determined.

[0037] In step S102, based on the boundary inductance value corresponding to the fan at each to-be-tested rotating speed value, the correlation between the rotating speed and the inductance of the fan is obtained, and the correlation is used to determine the working inductance when the fan operates at different rotating speeds.

[0038] In the present embodiment, after obtaining the correlation between the rotating speed and the inductance of the fan, for any rotating speed in the rated rotating speed range, the corresponding inductance value can be obtained based on the correlation.

[0039] Further, in some embodiments, after determining the set rotating speed when the fan operates, the working inductance when the fan operates at the set rotating speed can be determined.

[0040] By using the above method, the boundary inductance value corresponding to each to-be-tested rotating speed value is determined, and based on the boundary inductance value corresponding to the fan at each to-be-tested rotating speed value, the correlation between the rotating speed and the inductance of the fan is obtained. Since the rotating speed fluctuation of the fan corresponding to any to-be-tested rotating speed value and the candidate inductance value as the control parameter satisfies the preset fluctuation range, the working inductance of the fan operating at any rotating speed can be obtained through the correlation, so that the rationality of the fan parameter determination is improved, and further the stability of the fan operating at different rotating speeds is improved.

[0041] In some embodiments, the boundary inductance value can include a first inductance value, in which case, determining the boundary inductance value corresponding to the to-be-tested rotating speed value can include the following steps: Obtaining a first to-be-tested inductance value; Taking the to-be-tested rotating speed value and the first to-be-tested inductance value as control parameters, controlling the fan to operate for a preset time length; Obtaining the rotating speed fluctuation of the fan within the preset time length; In the case where the rotating speed fluctuation satisfies the preset fluctuation range, the first to-be-tested inductance value is increased to obtain a new first to-be-tested inductance value, and the step of taking the to-be-tested rotating speed value and the first to-be-tested inductance value as control parameters to control the fan to operate for a preset time length is returned to be executed until the rotating speed fluctuation exceeds the preset fluctuation range, and the most recently determined first to-be-tested inductance value is taken as the first inductance value.

[0042] In some embodiments, the first to-be-tested inductance value can be an inductance value indicated in a specification book of the fan when the fan is shipped. In this way, the fan speed can be tested iteratively, and the testing efficiency is improved.

[0043] In some embodiments, the increasing of the first to-be-tested inductance value can be an increase by a preset percentage based on the first to-be-tested inductance value. For example, the first to-be-tested inductance value is increased by 10% each time. In this way, the inductance value can be tested iteratively, and the testing efficiency is improved.

[0044] In some embodiments, the preset fluctuation range can be a preset speed value. For example, assuming that the to-be-tested speed value is 100 revolutions per minute, and the preset speed value is 10 revolutions per minute, when the actual speed of the fan is 80 revolutions per minute, the speed fluctuation of the fan does not meet the preset fluctuation range, and when the actual speed of the fan is 95 revolutions per minute, the speed fluctuation of the fan meets the preset fluctuation range.

[0045] In some embodiments, the boundary inductance value includes a second inductance value, and determining the boundary inductance value corresponding to the to-be-tested speed value includes: obtaining a second to-be-tested inductance value; controlling the fan to run for a preset time length with the to-be-tested speed value and the second to-be-tested inductance value as control parameters; obtaining a speed fluctuation of the fan within the preset time length; in a case where the speed fluctuation meets the preset fluctuation range, decreasing the second to-be-tested inductance value to obtain a new second to-be-tested inductance value, and returning to the step of controlling the fan to run for a preset time length with the to-be-tested speed value and the second to-be-tested inductance value as control parameters until the speed fluctuation exceeds the preset fluctuation range, and taking the most recently determined second to-be-tested inductance value as the second inductance value.

[0046] Similarly, in some embodiments, the second to-be-tested inductance value can be an inductance value indicated in a specification book of the fan when the fan is shipped. In this way, the fan speed can be tested iteratively, and the testing efficiency is improved.

[0047] Similarly, in some embodiments, the decreasing of the first to-be-tested inductance value can be an increase by a preset percentage based on the second to-be-tested inductance value. For example, the first to-be-tested inductance value is decreased by 10% each time. In this way, the inductance value can be tested iteratively, and the testing efficiency is improved.

[0048] It should be noted that the order of determining the first inductance value and the second inductance value is not limited. The first inductance value can be determined first, and then the second inductance value can be determined, or the second inductance value can be determined first, and then the first inductance value can be determined.

[0049] In some embodiments, the boundary inductance values include a first inductance value and a second inductance value, and the relationship between the speed and the inductance of the fan is obtained based on the boundary inductance values corresponding to each of the to-be-tested speed values. For any to-be-tested speed value, an average value of the first inductance value and the second inductance value corresponding to the to-be-tested speed value is obtained. A first difference value between the average value and the first inductance value and a second difference value between the average value and the second inductance value are obtained. In a case where the absolute values of the first difference value and the second difference value corresponding to each of the to-be-tested speed values exceed the respective preset difference threshold values, the relationship between the speed and the inductance of the fan is obtained based on the boundary inductance values corresponding to each of the to-be-tested speed values.

[0050] In the embodiment, the absolute values of the first difference value and the second difference value corresponding to each of the to-be-tested speed values are obtained, and each of the to-be-tested speed values further corresponds to a preset difference threshold value. When the absolute values of the first difference value and the second difference value corresponding to each of the to-be-tested speed values are greater than the respective preset difference threshold values, the relationship between the speed and the inductance of the fan is further obtained based on the boundary inductance values corresponding to each of the to-be-tested speed values.

[0051] When the absolute value of the first difference value or the absolute value of the second difference value corresponding to any to-be-tested speed value is less than the preset difference threshold value corresponding to the to-be-tested speed value, it indicates that the inductance of the fan is relatively sensitive, and it can be determined that the fan does not meet the use requirement, and the fan can be prompted to be improved.

[0052] In some embodiments, the method of the embodiment of the present disclosure can further include the following steps. A target speed region to which the to-be-tested speed value belongs is determined. Based on a corresponding relationship between the speed region and the difference threshold value, a preset difference threshold value corresponding to the target speed region is determined.

[0053] In the embodiment, different speed values can correspond to different preset difference threshold values.

[0054] In the embodiment, the to-be-tested speed values are divided into speed regions, and the difference threshold values corresponding to different speed regions are different. Therefore, in the embodiment of the present disclosure, the target speed region of the to-be-tested speed value is first determined, and then the preset difference threshold value corresponding to the target speed region is further determined according to the corresponding relationship between the speed region and the difference threshold value which is set in advance.

[0055] For example, the speed values can be divided into a high-speed region, a medium-speed region, and a low-speed region, and the high-speed region, the medium-speed region, and the low-speed region correspond to different difference threshold values, respectively.

[0056] By adopting the above method, by determining the target speed zone to which the to-be-tested speed value belongs, and based on the corresponding relationship between the speed zone and the preset difference threshold value, the preset difference threshold value corresponding to the target speed zone is determined, which can reduce the influence caused by different motor speeds.

[0057] In some embodiments, the preset difference threshold values corresponding to different speed values can also be the same.

[0058] In some embodiments, based on the boundary inductance values of the fan corresponding to each to-be-tested speed value, the correlation between the speed of the fan and the inductance can comprise the following steps: For any to-be-tested speed value, the average value of the boundary inductance value corresponding to the to-be-tested speed value is obtained; Based on the average values of the fan corresponding to each to-be-tested speed value, the correlation between the speed of the fan and the inductance is obtained.

[0059] Considering that the correlation between the speed of the fan and the inductance is used to determine the working inductance when the fan operates at different speeds, in order to guarantee the reliability of the fan operation in subsequent application of the correlation to control the operation of the fan, in the embodiment, the correlation between the speed of the fan and the inductance can be obtained based on the average values of the fan corresponding to each to-be-tested speed value. By such a setting, even if there is a jump in the working inductance when the fan operates at a certain speed, within a certain jump range, it can be guaranteed that the speed fluctuation of the fan corresponding to the inductance after the jump satisfies the preset fluctuation range when the fan operates at the speed and the inductance after the jump.

[0060] In some embodiments, after obtaining the average values of the fan corresponding to each to-be-tested speed value, the correlation between the speed of the fan and the inductance can be obtained by applying the curve drawing method or the interpolation method.

[0061] In some embodiments, after obtaining the boundary inductance values (i.e., the first inductance value and the second inductance value) of the fan corresponding to each to-be-tested speed value, based on the first inductance value corresponding to each to-be-tested speed value, the correlation between the speed of the fan and the first inductance value can be obtained by applying the curve drawing method or the interpolation method, and based on the second inductance value corresponding to each to-be-tested speed value, the correlation between the speed of the fan and the second inductance value can be obtained by applying the curve drawing method or the interpolation method. In this way, when determining the working inductance when the fan operates at different speeds, one boundary working inductance value can be determined based on the correlation between the speed of the fan and the first inductance value, another boundary working inductance value can be determined based on the correlation between the speed of the fan and the second inductance value, and then any inductance value within the inductance interval corresponding to the two boundary working inductance values can be selected as the working inductance value of the fan.

[0062] In the following, a complete embodiment is used to introduce the fan parameter determination method of the embodiments of the present disclosure in detail: After obtaining the new fan, the fan resistance, fan counter electromotive force, moment of inertia and other related electrical parameters are written into the electronic equipment program according to the specification.

[0063] The minimum speed and the maximum speed of the fan are determined as the to-be-measured speed values, and in addition, starting from the minimum speed, every 100 revolutions between the minimum speed and the maximum speed is determined as a to-be-measured speed value.

[0064] For any to-be-measured speed value, when the fan speed runs at the speed value, the inductance first runs at the value in the specification for a time t, and during the test process, it is detected whether the fan speed fluctuation is within the preset fluctuation range; then the inductance is increased by a fixed percentage in the program, and runs stably for a time t, and during this period, it is detected whether the fan speed fluctuation is within the preset fluctuation range; the increase is continued until the fan speed fluctuation exceeds the preset fluctuation range, and the first inductance value is obtained. Similarly, the inductance is decreased in the same step as the increase, and the smallest inductance value at which the speed fluctuation exceeds the preset fluctuation range is found, and the second inductance value is obtained. Thus, the boundary inductance value corresponding to the to-be-measured speed value is obtained.

[0065] Further, the average of the boundary inductance values corresponding to each to-be-measured speed value can be determined.

[0066] The above method is sequentially performed for each to-be-measured speed value, and the average of the boundary inductance values corresponding to each to-be-measured speed value can be obtained. In an embodiment, the above process of determining the boundary inductance value can be sequentially performed in the order of the to-be-measured speed values from small to large.

[0067] The to-be-measured speed values are divided into a high-speed zone, a medium-speed zone and a low-speed zone, each speed zone corresponding to a preset difference threshold value, for example, the preset difference threshold value corresponding to the high-speed zone is A1; the preset difference threshold value corresponding to the medium-speed zone is A2; and the preset difference threshold value corresponding to the low-speed zone is A3. It is respectively judged whether the absolute values of the first difference and the second difference corresponding to each to-be-measured speed value exceed the respective preset difference threshold values.

[0068] If both exceed, the correlation between the speed of the fan and the inductance is obtained based on the average of the boundary inductance values of the fan corresponding to each to-be-measured speed value.

[0069] Subsequently, the fan is run in the actual running process based on the correlation, so that the reliability of the fan is guaranteed when the inductance of the fan fluctuates within a certain range.

[0070] Figure 2 is a flow chart of a fan parameter determination method according to an example embodiment, as shown in Figure 2 The method can be used in a fan device, and the method can include the following steps: In step S201, a set rotating speed of the fan is acquired.

[0071] In step S202, according to the correlation between the rotating speed and the inductance, a target inductance value corresponding to the set rotating speed is determined.

[0072] The correlation between the rotating speed and the inductance is determined according to the fan parameter determination method in the foregoing embodiment.

[0073] In step S203, the fan is controlled according to the target inductance value and the set rotating speed.

[0074] The set rotating speed of the fan can be understood as a set rotating speed at which the fan operates. For example, the fan can be controlled to operate at 500 revolutions per minute by a remote control device.

[0075] In this embodiment, the set rotating speed of the fan is acquired first, then, according to the pre-stored correlation between the rotating speed and the inductance, the target inductance value corresponding to the set rotating speed is determined, and then the target inductance value and the set rotating speed are taken as the control parameters of the fan to control the fan.

[0076] By setting the correlation between the rotating speed and the inductance, the fan can determine the corresponding working inductance value at any set rotating speed. Since the fan operates at the set rotating speed and the corresponding working inductance as the control parameters, the corresponding rotating speed fluctuation of the fan meets the preset fluctuation range, thereby improving the stability of the fan operating at different rotating speeds.
