Description

Technical Field

[0001] The embodiments of the present invention relate to the field of intelligent devices, and in particular to a fan control method and a fan. Background Art

[0002] With the development of technology, fans are becoming more and more intelligent. At present, fans are integrated with voice prompts to remind the current working status of the fan, so that users can understand the working status of the fan in time. Alternatively, an indicator light is installed in the fan to remind the current working status of the fan.

[0003] However, the inventors have found that the fan has at least the following problems: the user does not need to know the fan's working status all the time, especially at night, the light of the fan's indicator light and the prompt voice of the fan will affect the user's rest. The light of the fan's indicator light and the voice prompt function of the fan can only be turned on or off manually by the user, and cannot intelligently adapt to the user's needs to automatically turn on or off the indicator light or the voice prompt function of the fan. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide a fan control method and a fan, which can automatically detect and determine whether the operation of the fan affects the user's rest, and when it is determined that the user is resting, automatically adjust the fan to night mode to avoid the automatic prompt function when the fan is working affecting the user's rest, making the fan control more intelligent.

[0005] To solve the above technical problems, an embodiment of the present invention provides a fan control method, including: starting timing when the light intensity of the environment in which the fan is located is lower than a preset threshold; if the timing is interrupted by a preset event, restarting the timing after the preset event is executed; if the timing duration reaches a first preset duration, controlling the fan to adjust to night mode; wherein, the brightness of the indicator light of the fan in the night mode is lower than the brightness of the indicator light of the fan in the normal mode, and / or, the voice prompt function of the fan in the night mode is in a turned off state.

[0006] An embodiment of the present invention also provides a fan, comprising: a shell, the shell comprising a base, an indicator light, a voice module, and a processor; the indicator light is arranged at the light-transmitting hole of the base; the voice module and the processor are both arranged in the inner cavity of the base; the indicator light and the voice module are both connected to the processor, the indicator light prompts the working status of the fan through brightness, and the voice module prompts the working status of the fan through a voice prompt function; the processor is used to control the brightness of the indicator light and the voice prompt function status of the voice module to realize the above-mentioned fan control method.

[0007] An embodiment of the present invention further provides a computer-readable storage medium storing a computer program, wherein the computer program implements the above-mentioned fan control method when executed by a processor.

[0008] Compared with the prior art, the embodiment of the present invention determines whether the night condition is met according to the light intensity of the environment where the fan is located, starts timing when the night condition is met, and determines that the user does not need the fan to provide a prompt function when the timing is not interrupted and the timing time continues to reach the first preset time. It is highly likely that the user is in a resting state. Therefore, the fan is automatically adjusted to night mode to avoid the brightness of the prompt light or the voice prompt function of the fan affecting the user's rest. In addition, if the timing is interrupted by a preset event during the timing process that meets the night condition, the timing is restarted after the preset event is executed. Since if a preset event is detected during the timing of the fan, it means that the environment where the fan is located has changed or there is an interaction with the fan, the occurrence of the preset event is detected to represent that the night condition detected in the previous sequence has changed, or the user is not in a resting state. Regardless of any of the above conditions, the situation that the user needs to rest and the fan does not provide a prompt function is not met. Therefore, the timing duration is an invalid value, and it is necessary to wait for the preset event to be executed before restarting the timing to ensure the accuracy of the fan's adaptive adjustment and avoid the fan automatically turning off the prompt function when the user is active, affecting the user experience.

[0009] In addition, the preset event is: interaction between the user and the fan; if a user's voice interaction command, touch interaction command, and / or mechanical adjustment command is detected during the timing process, it is determined that the timing is interrupted by the preset event.

[0010] In addition, after the fan is controlled to be adjusted to the night mode, the method further includes: if the user's interaction with the fan is detected, the fan is adjusted to the weak working mode; wherein the brightness of the indicator light of the fan in the weak working mode is higher than the brightness of the indicator light of the fan in the night mode, and the brightness of the indicator light of the fan in the weak working mode is lower than the brightness of the indicator light of the fan in the normal mode. In this way, the indicator light can be awakened during the user's interaction with the fan, and the brightness of the indicator light is lower than the brightness of the indicator light in the normal mode to avoid glare.

[0011] In addition, after the fan is adjusted to the weak working mode, the method further includes: starting timing when it is detected that the user's interaction with the fan ends and the light intensity of the environment where the fan is located is lower than a preset threshold; when the timing duration reaches a second preset time, controlling the fan to be adjusted from the weak working mode to the night mode; wherein the second preset time is less than the first preset time. In this way, the fan can be restored to the night mode more quickly after the user has a brief interaction with the fan.

[0012] In addition, the brightness of the indicator light changes with the light intensity of the environment in which the fan is located, so that the brightness of the indicator light felt by the user is adapted to the brightness of the ambient light.

[0013] In addition, the timing being interrupted by a preset event includes: during the timing process, if it is detected that the light intensity of the environment where the fan is located is higher than the preset threshold, it is determined that the timing is interrupted by the preset event.

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it can be understood by those skilled in the art that in the embodiments of the present invention, many technical details are provided to enable readers to better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present invention can be implemented.

[0024] The following embodiments are divided for the convenience of description and shall not constitute any limitation on the specific implementation of the present invention. The embodiments may be combined with each other and referenced to each other without contradiction.

[0025] An embodiment of the present invention relates to a fan control method, comprising: starting timing when the light intensity of the environment in which the fan is located is lower than a preset threshold; if the timing is interrupted by a preset event, restarting the timing after the preset event is executed; if the timing duration reaches a first preset time, controlling the fan to adjust to night mode; wherein, the brightness of the indicator light of the fan in night mode is lower than the brightness of the indicator light of the fan in normal mode, and / or, the voice prompt function of the fan in night mode is in a turned off state.

[0026] Compared with the prior art, the embodiment of the present invention determines whether the night condition is met according to the light intensity of the environment where the fan is located, starts timing when the night condition is met, and determines that the user does not need the fan to provide a prompt function when the timing is not interrupted and the timing time continues to reach the first preset time. It is highly likely that the user is in a resting state. Therefore, the fan is automatically adjusted to night mode to avoid the brightness of the prompt light or the voice prompt function of the fan affecting the user's rest. In addition, if the timing is interrupted by a preset event during the timing process that meets the night condition, the timing is restarted after the preset event is executed. Since if a preset event is detected during the timing of the fan, it means that the environment where the fan is located has changed or there is an interaction with the fan, the occurrence of the preset event is detected to represent that the night condition detected in the previous sequence has changed, or the user is not in a resting state. Regardless of any of the above conditions, the situation that the user needs to rest and the fan does not provide a prompt function is not met. Therefore, the timing duration is an invalid value, and it is necessary to wait for the preset event to be executed before restarting the timing to ensure the accuracy of the fan's adaptive adjustment and avoid the fan automatically turning off the prompt function when the user is active, affecting the user experience.

[0027] The fan control rules of this implementation are described in detail below. The following content is only implementation details provided for easy understanding and is not necessary for implementing this solution.

[0028] like Figure 1 As shown, the fan control method includes the following steps:

[0029] Step 101, determining whether the light intensity of the environment where the fan is located is lower than a preset threshold.

[0030] Specifically, the light intensity of the environment in which the fan is located is used to determine whether the night condition is met. When the light intensity of the environment in which the fan is located is lower than the preset threshold, it means that the ambient light is weak and the probability that the user is in a resting state is high. The intensity of the ambient light can be detected by the photoresistor part set on the fan main control board. The photoresistor part is integrated on the side of the main control board facing the surface of the base, so that the ambient light can be irradiated on the photoresistor part through the surface of the base, so that the photoresistor part can receive light. Since the main control board of the fan is usually arranged inside the fan, it is necessary to open a hole at the surface position of the base corresponding to the photoresistor part to facilitate the ambient light to enter the position of the photoresistor part inside the fan. In addition, in order to improve the light receiving sensitivity, a light guide column can also be added at the surface position of the photoresistor part and the corresponding base, and the light guide column assists in guiding the ambient light into the position of the photoresistor part inside the fan. The light guide column is made of black transparent material, which can well hide the photoresistor part on the main control board while ensuring light transmission. In addition, a light-transmitting film is added at the position of the light guide column to prevent dust in the external environment from entering the fan and polluting the internal parts of the fan.

[0031] If the determination result is no, step 101 is repeated to determine whether the light intensity of the environment where the fan is located is lower than a preset threshold.

[0032] If the judgment result is yes, then the process goes to step 102 and starts timing.

[0033] Step 103: When the timing duration is less than the first preset duration, determine whether a preset event occurs.

[0034] Specifically, since the purpose of detecting the preset event is to determine whether the reminder function of the fan may affect the user, the basis for determining the occurrence of the preset event in this embodiment may be to determine whether the occurrence of the event represents that the user is not in a resting state. For example, the preset event may be an interaction between the user and the fan, or a change in the environment in which the fan is located.

[0035] If the preset event is an interaction between the user and the fan, then when the timing duration is less than the first preset time, if the user's voice interaction command, touch interaction command, and / or mechanical adjustment command are detected, it is determined that the timing is interrupted by the preset event. Voice interaction command refers to the user triggering the voice interaction function of the fan through a specific wake-up word, touch interaction command refers to the user inputting a touch command through the control panel on the fan, and mechanical adjustment command refers to the user issuing a control command through a mechanical button or knob on the fan.

[0036] If the preset event is a change in the environment where the fan is located, then when the timing duration is less than the first preset time, if it is detected that the light intensity of the environment where the fan is located is higher than the preset threshold, it is determined that the timing is interrupted by the preset event.

[0037] If the result of determining whether a preset event occurs is yes, the process proceeds to step 104. After the preset event is detected, the process returns to step 101 to determine again whether the light intensity of the fan environment is lower than a preset threshold. If the light intensity is lower than a preset threshold, the timing is restarted.

[0038] Specifically, in the case where the timing is interrupted by a preset event, after the preset event is executed, it is possible to re-detect whether the light intensity of the environment in which the fan is located meets the condition of being lower than the preset threshold, and restart the timing after the light intensity is lower than the preset threshold. In addition, the duration of the re-timing can also be based on the first preset duration, or it can be adjusted to a suitable first preset duration according to the preset event that occurs. For example, if the preset event that occurs is detected to be the fan being adjusted to the swinging head working mode, etc., it means that the user is not currently affected by noise. At this time, the first preset duration can be appropriately increased, and the duration of the re-timing can be increased before switching to the night mode. For another example, if the preset event that occurs is detected to be the user adjusting the fan to the silent mode, etc., it means that the user needs a quiet environment. At this time, the first preset duration can be appropriately reduced, and the duration of the re-timing can be reduced. It can switch to the night mode more quickly, and the conditions for switching to the night mode can be adaptively adjusted based on user behavior, making the control of the fan more flexible.

[0039] If the result of the determination as to whether the preset event occurs is no, the process proceeds to step 105 , and when the timing duration reaches a first preset duration, the fan is controlled to be adjusted to a night mode.

[0040] Specifically, the noise emitted by the fan will be reduced in night mode, and the noise here includes light noise and sound noise. That is, the brightness of the indicator light of the fan in night mode is lower than that of the indicator light of the fan in normal mode, and / or the voice prompt function of the fan in night mode is turned off to avoid automatic voice prompts. In addition, other strategies for reducing the noise emitted by the fan can be set in night mode, for example, reducing the speed of the fan, adjusting the fan to a silent working state, etc., which are not listed here one by one.

[0041] In addition to the night mode and normal mode, you can also set the middle gear according to actual needs. For example, the middle gear set to the weak working mode, the brightness of the fan indicator light in the weak working mode is higher than the brightness of the fan indicator light in the night mode, and the brightness of the fan indicator light in the weak working mode is lower than the brightness of the fan indicator light in the normal mode. Figure 2 As shown, the following steps are included:

[0042] Step 201, when the fan is in night mode, if interaction between the user and the fan is detected, the fan is adjusted to a low-speed working mode.

[0043] Specifically, the interaction between the user and the fan includes at least: voice interaction instructions, touch interaction instructions, and / or mechanical adjustment instructions issued by the user to the fan. In order to restore to night mode more quickly, the fan switches to a weak working mode after detecting a brief interaction with the user. The brightness of the indicator light of the fan in the weak working mode is higher than that of the fan in the night mode, and the brightness of the indicator light of the fan in the weak working mode is lower than that of the fan in the normal mode. This can wake up the indicator light during the interaction between the user and the fan, and the brightness of the indicator light is weaker than that of the indicator light in the normal mode to avoid glare from strong light. In addition, the voice prompt function of the fan can be adjusted to the on state in the weak working mode, so that the fan can give voice feedback during the interaction between the user and the fan.

[0044] Step 202, when it is detected that the user's interaction with the fan ends and the light intensity of the environment where the fan is located is lower than a preset threshold, the timing starts, and when the timing duration reaches a second preset time, the fan is controlled to adjust from a low-speed working mode to a night mode.

[0045] Specifically, the ambient light intensity needs to be re-detected before the timing is interrupted and restarted to avoid changes in the ambient light intensity during the timing interruption time. The second preset time set for switching from the low-speed working mode to the night mode is shorter than the first preset time set for switching from the normal mode to the night mode. This allows the user to return to the night mode more quickly after a brief interaction with the fan in the night mode.

[0046] Compared with the prior art, the embodiments of the present invention, in addition to the normal mode and night mode of the fan, additionally add a weak gear working mode, thereby improving the flexibility of fan control, making the control of the fan more in line with the actual needs of users, and helping to improve the user experience.

[0047] In actual applications, the normal working mode of the fan can also be set to three working modes: high, medium, and weak. Among them, the brightness of the indicator light of the fan in the high working mode is higher than the brightness of the indicator light of the fan in the medium working mode, the brightness of the indicator light of the fan in the medium working mode is higher than the brightness of the indicator light of the fan in the low working mode, and the brightness of the indicator light of the fan in the low working mode is higher than the brightness of the indicator light of the fan in the night mode. In order to achieve the brightness of the indicator light changing with the light intensity of the environment in which the fan is located, the working mode of the fan can be adjusted based on the light intensity of the ambient light, as follows:

[0048] Based on the brightness of the indicator lights in different working modes, the thresholds of the light intensity of the corresponding ambient light in different working modes are set respectively. It is assumed that the light intensity threshold set for switching from the high-end working mode to the mid-range working mode is N1, the light intensity threshold set for switching from the mid-range working mode to the low-end working mode is N2, and the light intensity threshold set for switching from the low-end working mode to the night mode is N3. Detect the light intensity N of the current environment where the fan is located. If it is detected that the light intensity N of the environment is less than N1, and the duration of N being greater than N2 reaches the preset corresponding time threshold for the switching working mode, the working mode of the fan is switched from the high-end working mode to the mid-range working mode; detect the light intensity N of the current environment where the fan is located. If it is detected that the light intensity N of the environment is less than N2, and the duration of N being greater than N3 reaches the preset corresponding time threshold for the switching working mode, the working mode of the fan is switched from the mid-range working mode to the low-range working mode; detect the light intensity N of the current environment where the fan is located. If it is detected that the light intensity N of the environment is less than N3, and the duration reaches the preset corresponding time threshold for the switching working mode, the working mode of the fan is switched from the low-end working mode to the night mode. The above-mentioned method for determining the duration is: the light intensity of the environment where the fan is located does not exceed the duration within the light intensity threshold range of each working mode switching, and if it exceeds the light intensity threshold range of each working mode switching, the timing time is reset. The time thresholds corresponding to the above-mentioned working mode switching can be set to the same value. When switching the working mode, the brightness change of the indicator light can change linearly, that is, gradually weaken or gradually increase the brightness to the brightness of the indicator light in the changed working mode.

[0049] In addition, in each working mode, in addition to the different indicator light brightness, there are also differences in the voice prompt function. The prompt sound intensity of the fan's voice prompt function in the high-end working mode is higher than the prompt sound intensity in the medium-end working mode, the prompt sound intensity of the fan's voice prompt function in the medium-end working mode is higher than the prompt sound intensity in the low-end working mode, and the prompt sound intensity of the fan's voice prompt function in the low-end working mode is higher than the prompt sound intensity in the night mode.

[0050] The step division of the various methods above is only for clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the protection scope of the present invention. Adding insignificant modifications or introducing insignificant designs to the algorithm or process without changing the core design of the algorithm and process are all within the protection scope of the invention.

[0051] An embodiment of the present invention also relates to a fan, comprising: a shell, the shell comprising a base, an indicator light, a voice module, and a processor; the indicator light is arranged at a light-transmitting hole of the base; the voice module and the processor are both arranged in an inner cavity of the base; the indicator light and the voice module are both connected to the processor, the indicator light prompts the working status of the fan through brightness, and the voice module prompts the working status of the fan through a voice prompt function; the processor is used to control the brightness of the indicator light and the voice prompt function status of the voice module to implement the above-mentioned fan control method.
