[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0029] According to an embodiment of the present invention, an embodiment of a fan control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0030] In this embodiment, a fan control method is provided, which can be used in a controller. Figure 1 FIG. 1 is a flow chart of a fan control method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0031] Step S101 , obtaining the current ambient temperature and the current ambient humidity, and determining a first wind speed level corresponding to the current ambient temperature and a second wind speed level corresponding to the current ambient humidity.

[0032] The embodiment of the present invention can obtain the current ambient temperature and the current ambient humidity, and then determine the corresponding first wind speed level according to the current ambient temperature, and determine the corresponding second wind speed level according to the current ambient humidity. The method of determining the wind speed level based on temperature or humidity is not limited. For example, a relationship curve between different ambient temperatures or ambient humidity and wind speed levels is established in advance based on multiple practices of user experience or based on human experience. When the current ambient temperature and the current ambient humidity are obtained, they are compared with the established relationship curve to determine the first wind speed level corresponding to the current ambient temperature and the second wind speed level corresponding to the current ambient humidity. This is just an example.

[0033] Step S102 : collecting the current user's body surface temperature distribution and comparing it with a preset normal temperature distribution to determine a third wind speed level corresponding to the current user's body surface temperature distribution.

[0034] In an embodiment of the present invention, the current user's body surface temperature distribution can be collected through a human body temperature distribution collection device, and compared with a preset normal temperature distribution. The wind speed corresponding to the normal temperature distribution can be set by the user or a professional, and the current user's body surface temperature distribution can be compared with the normal temperature distribution. If the difference between the two is small, the third wind speed corresponding to the current user's body surface temperature distribution can be determined to be the wind speed corresponding to the preset normal temperature distribution. If the temperature of some areas in the current user's body surface temperature distribution is significantly different from the normal temperature, such as a difference of 2-3°C, corresponding adjustments can be made based on the wind speed corresponding to the normal temperature distribution to determine the third wind speed, which is only used as an example.

[0035] Step S103: determining a target wind speed based on the first wind speed, the second wind speed, and the third wind speed, and controlling the fan to operate at the target wind speed.

[0036] The embodiment of the present invention can determine the target wind speed based on the determined first wind speed, second wind speed and third wind speed, wherein there is no limitation on how to determine the target wind speed. For example, it can be determined first whether the same wind speed exists among the three wind speeds. If the same wind speed exists, the wind speed with the largest number of repetitions is used as the target wind speed. If the three wind speeds are different, the user can be prompted to select a wind speed so that the user can set the wind speed of his or her own needs. The wind speed with the lowest gear among the three wind speeds can also be selected as the target wind speed. Subsequently, the target wind speed is re-determined based on the ambient temperature, humidity and user's body surface temperature. This is just an example.

[0037] The fan control method provided in this embodiment obtains the current ambient temperature and the current ambient humidity, determines the first wind speed corresponding to the current ambient temperature, and the second wind speed corresponding to the current ambient humidity; collects the current user's body surface temperature distribution and compares it with the preset normal temperature distribution to determine the third wind speed corresponding to the current user's body surface temperature distribution; based on the first wind speed, the second wind speed and the third wind speed, determines the target wind speed, and controls the fan to operate at the target wind speed. It can detect the ambient temperature, humidity and human body surface temperature in real time, and intelligently adjust the fan's wind speed to ensure the user's comfort in different environments.

[0038] In this embodiment, a fan control method is provided, which can be used in a controller. Figure 2 FIG. 1 is a flow chart of a fan control method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0039] Step S201 , obtaining the current ambient temperature and the current ambient humidity, and determining a first wind speed level corresponding to the current ambient temperature and a second wind speed level corresponding to the current ambient humidity.

[0040] Specifically, the above step S201 includes:

[0041] Step S2011: Based on the preset correspondence between different wind speed gears and different ambient temperature ranges and the ambient temperature range in which the current ambient temperature is located, the corresponding wind speed gear is determined as the first wind speed gear.

[0042] The embodiment of the present invention does not limit the specific setting of the fan speed level, which can be set according to the actual product, for example, Figure 3As shown, the wind speed gear includes low speed gear, medium speed gear and high speed gear. As an example only, the correspondence between different wind speed gears and different ambient temperature ranges can be pre-set. For example, when the ambient temperature T≥30℃, the wind speed gear can be determined as high speed gear, when 25℃≤T<30℃, the wind speed gear can be determined as medium speed gear, and when the ambient temperature T<25℃, the wind speed gear can be determined as low speed gear. As an example only, after obtaining the current ambient temperature, the ambient temperature range in which the current ambient temperature is located can be determined first, and then the wind speed gear corresponding to the ambient temperature range can be determined as the first wind speed gear.

[0043] Step S2012: Based on the preset correspondence between different wind speed gears and different ambient humidity ranges and the ambient humidity range in which the current ambient humidity is located, the corresponding wind speed gear is determined as the second wind speed gear.

[0044] The embodiment of the present invention sets the corresponding relationship between different wind speed gears and different ambient humidity ranges, for example, Figure 3 As shown, the ambient humidity When the wind speed gear is set to high gear, the ambient humidity is 55%. When the wind speed gear can be determined to be medium speed gear, the ambient humidity When the wind speed gear can be determined as the low speed gear, it is only for example. Therefore, after obtaining the current ambient humidity, the ambient humidity range in which the current ambient humidity is located can be determined first, and then the wind speed gear corresponding to the ambient humidity range can be determined as the second wind speed gear.

[0045] The present invention pre-sets the correspondence between different wind speed gears and different ambient temperature ranges and ambient humidity ranges. Based on the current ambient temperature and ambient humidity, the ambient temperature range and ambient humidity range are determined respectively, and then the corresponding wind speed gears are determined as the first wind speed gear and the second wind speed gear respectively, so that the wind speed gear can be accurately determined.

[0046] Step S202 : collecting the current user's body surface temperature distribution and comparing it with a preset normal temperature distribution to determine a third wind speed level corresponding to the current user's body surface temperature distribution.

[0047] Specifically, the current user's body surface temperature distribution is compared with the preset normal temperature distribution to determine whether there is an area in the current user's body surface temperature distribution whose temperature is lower than the preset normal temperature and whose temperature difference with the normal temperature is greater than a preset first temperature difference threshold, and / or, determine whether the temperature difference between the current area and other areas except the current area in the current user's body surface temperature distribution is greater than a preset second temperature difference threshold; if there is an area in the current user's body surface temperature distribution whose temperature is lower than the preset normal temperature and whose temperature difference with the normal temperature is greater than the preset first temperature difference threshold, and / or, the temperature difference between the current area and other areas except the current area is greater than the preset second temperature difference threshold, obtain the current wind speed gear; perform a downshift operation on the current wind speed gear to obtain the wind speed gear after downshifting, and use it as the third wind speed gear.

[0048] In an embodiment of the present invention, a human body temperature distribution acquisition device can be used in advance to collect the normal temperature distribution of the human body surface when the user is not sweating, as a reference baseline. When the user uses the fan, the human body temperature distribution acquisition device can continue to be used to monitor the temperature distribution of the human body surface in real time. After obtaining the current user's body surface temperature distribution, it can be compared with the normal temperature distribution to determine whether there is an area in the current user's body surface temperature distribution whose temperature is lower than the preset normal temperature and the temperature difference with the normal temperature is greater than a preset first temperature difference threshold, that is, whether an area with a significantly lower temperature is stored. It can also be determined whether the temperature difference between the current area and other areas except the current area in the current user's body surface temperature distribution is greater than a preset second temperature difference threshold, that is, the temperature of the current human body part is significantly different from that of other parts. There is no limitation on the setting of the first temperature difference threshold and the second temperature difference threshold. For example, the first temperature difference threshold and the second temperature difference threshold can both be set to 2-3°C. This is just an example. For example, Figure 3 As shown, it is determined whether the current temperature distribution is 2 degrees Celsius lower than the body surface temperature of the normal temperature distribution.

[0049] In the embodiment of the present invention, if it is determined that there is an area in the current user's body surface temperature distribution where the temperature is lower than the preset normal temperature and the temperature difference from the normal temperature is greater than a preset first temperature difference threshold, and / or the temperature difference between the current area and other areas except the current area is greater than a preset second temperature difference threshold, and any of the above conditions is met, it can be determined that the current area may be sweating, that is, the user may be in a sweating state, and the current constant speed gear can be obtained, and a downshift operation can be performed on the current wind speed gear, for example, Figure 3As shown, if it is determined that the current temperature distribution is 2°C lower than the body surface temperature of the normal temperature distribution, if the current wind speed gear is the high gear, the wind speed gear will be reduced to the medium gear. If the current wind speed gear is the medium gear, the wind speed gear will be reduced to the low gear. If the current wind speed gear is the low gear, the wind speed gear can be kept at the low gear. This is just an example. If it is determined that the current user's body surface temperature distribution is slightly different from the normal temperature distribution, the current wind speed gear can still be used as the third wind speed gear.

[0050] The embodiment of the present invention determines that the current temperature distribution is significantly lower than the normal temperature distribution, indicating that the user may be sweating, and then downshifts the current wind speed level, thereby preventing the user from catching a cold after being blown by the wind due to sweating.

[0051] Step S203: determining a target wind speed based on the first wind speed, the second wind speed, and the third wind speed, and controlling the fan to operate at the target wind speed.

[0052] Specifically, the above step S203 includes:

[0053] Step S2031, determine the target wind speed based on the weighted value of the current ambient temperature corresponding to the first wind speed, the weighted value of the current ambient humidity corresponding to the second wind speed, and the weighted value of the current user's body surface temperature distribution corresponding to the third wind speed.

[0054] The embodiment of the present invention can pre-set corresponding weighted values ​​for different wind speed influencing factors, such as a weighted value corresponding to ambient temperature of 35%, a weighted value corresponding to ambient humidity of 25%, and a weighted value corresponding to user surface temperature distribution of 40%. As an example only, the target wind speed can be determined based on the weighted value of the first wind speed for ambient temperature, the weighted value of the second wind speed for ambient humidity, and the weighted value corresponding to the third wind speed for user surface temperature distribution. There is no limitation on how to determine the target wind speed based on the weighted value. For example, it can be determined whether there is the same wind speed among the three wind speeds. If there is the same wind speed, the corresponding weighted values ​​are added to obtain the weighted value corresponding to the wind speed. If the three wind speeds do not have the same wind speed, no weighting operation is required. Finally, the wind speed corresponding to the largest weighted value can be selected as the target wind speed. As an example only.

[0055] In a specific embodiment, Figure 3As shown, the wind speed gears of the fan include low speed gear, medium speed gear and high speed gear. Based on the preset correspondence between different fan influencing factors and different weighted values, the first wind speed gear, the second wind speed gear and the third wind speed gear, the weighted value corresponding to each wind speed gear of all the wind speed gears of the fan (i.e., low speed gear, medium speed gear and high speed gear) can be calculated, and the wind speed gear with the largest weighted value is selected as the target wind speed gear. For example, if the first wind speed gear is high speed gear, the second wind speed gear is medium speed gear, and the third wind speed gear is medium speed gear, then based on the weighted value corresponding to each wind speed influencing factor, the weighted value of the low speed gear is calculated to be 0.00, the weighted value of the medium speed gear is 0.40+0.25=0.65, and the weighted value of the high speed gear is 0.35. Then the wind speed gear with the largest weighted value, i.e., the medium speed gear, can be selected as the target wind speed gear, for example only.

[0056] The present invention determines the target wind speed based on the weighted values ​​of the corresponding fan influencing factors at different wind speeds, and can determine the most suitable wind speed operation to improve the user experience.

[0057] In this embodiment, a fan control method is provided, which can be used in a controller. Figure 4 FIG. 1 is a flow chart of a fan control method according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:

[0058] Step S401: Get the current ambient temperature and humidity, and determine the first wind speed corresponding to the current ambient temperature and the second wind speed corresponding to the current ambient humidity. Figure 2 Step S201 of the illustrated embodiment will not be described in detail here.

[0059] Step S402: collect the current user's body surface temperature distribution and compare it with the preset normal temperature distribution to determine the third wind speed corresponding to the current user's body surface temperature distribution. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0060] Step S403: Based on the first wind speed, the second wind speed and the third wind speed, determine the target wind speed and control the fan to operate at the target wind speed. Figure 2 Step S203 of the illustrated embodiment will not be described in detail here.

[0061] Step S404, collecting the distance between the user's face and the fan, and obtaining the user's height when the distance is less than a preset distance threshold; controlling the maximum height of the fan sweep to be no greater than the difference between the user's height and a preset height offset value.

[0062] The embodiment of the present invention can collect the distance D_face between the user's face and the fan, and determine whether D_face is less than a preset distance threshold. The setting of the distance threshold is not limited and can be set according to actual needs. For example, the distance threshold is 1 meter. Figure 3 As shown, if D_face is less than 1 meter, the user's height can be obtained, and the maximum height of the fan sweeping air can be controlled to be no greater than the difference between the user's height and the preset height offset value, wherein the setting of the preset height offset value is based on actual needs, such as 0.2 meters, which is only used as an example. There is no limitation on the method of controlling the maximum height of the fan sweeping air to be no greater than the difference between the user's height and the preset height offset value. For example, the user's absolute height can be measured, that is, the height from the ground to the top of the user's head is directly measured, the user's body height is measured, and then the difference with the preset height offset value is calculated. The relative height can also be measured, that is, the height of the user's head is detected, and 20 cm is subtracted from it to avoid the face. This is only used as an example.

[0063] The present invention avoids the discomfort caused by the wind blowing directly on the face by controlling the maximum height of the fan to be no greater than the difference between the user's height and a preset height offset value.

[0064] In an optional embodiment, in response to the user modifying the fan control parameters, the currently stored fan control parameters are updated based on the user-modified fan control parameters, and the fan control parameters include at least the correspondence between different wind speed influencing factors and different weighted values, the first temperature difference threshold, the second temperature difference threshold, the height offset value, and the correspondence between different wind speed gears and different ambient temperature ranges and different ambient humidity ranges.

[0065] Among them, factors affecting wind speed include at least ambient temperature, ambient humidity and user's body surface temperature distribution.

[0066] The fan of the embodiment of the present invention can establish a communication connection with a corresponding smartphone application, and the user can customize the fan control parameters through the application. For example, the user can adjust the weighted values ​​of "preventing users from catching colds", "ambient temperature adjustment" and "ambient humidity adjustment" in the APP to better suit personal preferences and actual conditions. The user can also set the height offset value based on the user's own height ratio. For example, the user can set the wind direction offset value to 0 cm, which means blowing directly on the face. It can also be set to other values, such as 10 cm or 30 cm, to meet different usage requirements. The temperature difference threshold, the correspondence between different wind speed gears and different ambient temperature ranges, and different ambient humidity ranges can also be set. As an example only, the controller can update the currently integrated and stored fan control parameters based on the fan control parameters modified by the user.

[0067] In the present invention, users can customize and modify fan control parameters, making fan control more flexible and able to meet the needs of different users.

[0068] In a specific embodiment, the initialization parameters are: setting the weighted value of user temperature distribution: 40%, the weighted value of ambient temperature adjustment: 35%, and the weighted value of ambient humidity adjustment: 25%; detecting the environment and human body conditions: obtaining the ambient temperature T = 31 ° C, the ambient humidity The user's face is D_face = 0.8 meters away from the fan, the user's skin temperature distribution T_body = 32°C (33.2°C 5 minutes ago), and the user's height H = 1.75 meters; Generate fan control strategy: Avoid direct blowing on the face: Adjust the wind direction so that the highest air outlet position is H-0.2m, that is, 1.55 meters, to prevent the user from catching a cold: If the current wind speed is medium, reduce it by one gear; otherwise, set it to medium, adjust the ambient temperature: Turn on the fan and set it to high speed, adjust the ambient humidity: Increase the air volume and set it to high speed; Calculate weighted values: To prevent the user from catching a cold: Weight 40%, it is recommended to Speed: medium speed (assuming it is not medium speed at present); ambient temperature adjustment: weight 35%, recommended wind speed: high speed; ambient humidity adjustment: weight 25%, recommended wind speed: medium speed; determine the final wind speed: calculate weighted values: low speed: 0.00, medium speed: 0.40+0.25=0.65, high speed: 0.35, judgment basis: select the wind speed gear with the largest weighted value, that is, medium speed; final fan control instruction: wind speed: medium speed, wind direction: make the highest air outlet position 1.55 meters to avoid direct blowing on the face. This is only an example. Please refer to the above embodiment for detailed description and will not be repeated here.
