Abstract
Description
Technical Field
[0001] This invention relates to the field of home appliance technology, and more specifically to a fan control method, control device, and computer-readable storage medium. Background Technology
[0002] As people's demands for comfort in their living environment increase, different users have different needs for fan airflow in different environments. In a home environment, users may prefer a gentle, quiet, and directional breeze while sleeping, while relaxing in the living room may require a wider and more even airflow. Traditional fan airflow methods are often relatively simple and cannot well meet these diverse and personalized needs. From a health perspective, inappropriate airflow methods may have adverse effects on users. For example, prolonged exposure to strong direct airflow may lead to muscle stiffness, colds, and other problems. Summary of the Invention
[0003] In view of this, the present invention provides a fan control method to solve the technical problem that fans in the prior art cannot intelligently adjust according to user status information.
[0004] In a first aspect, the present invention provides a fan control method, the control method comprising: receiving a user's request to start the fan; obtaining the user's status information; controlling the fan to start based on the user's status information, and executing a working mode corresponding to the status information.
[0005] Beneficial effects: The fan control method of the present invention realizes the different needs of users for air supply mode in multiple states. Through intelligent adjustment and control of the fan, it can accurately match the actual needs of users, thereby improving the user experience and meeting the personalized needs of users.
[0006] Specifically, assuming the fan has three airflow modes, after the fan starts, the system first checks whether the user has enabled the comfort mode. Before the check is complete, it operates at the default speed or setting. Conversely, if the comfort mode is enabled, the system will monitor and obtain the user's current status information in real time to dynamically adjust the airflow mode, ensuring that the user is always in the most suitable airflow environment.
[0007] In one optional implementation, the status information includes body temperature information. Obtaining the user's status information specifically includes: obtaining the user's body temperature information; determining the user's body surface temperature distribution information based on the body temperature information; and determining the status information based on the body surface temperature distribution information. The status information includes exercise status, resting status after exercise, and illness status.
[0008] Beneficial effects: By generating a user's body surface temperature map using thermal imaging sensor data, an image showing the distribution of the user's body surface temperature can be generated. It can be seen intuitively which parts of the body have higher temperatures. If the user's body surface temperature exceeds a certain threshold (e.g., 36°C), it is considered that the user may need rapid heat dissipation. In addition, it is necessary to distinguish whether the rise in body temperature is caused by illness or exercise. This can be distinguished by the rate and duration of the temperature rise, the time point of body temperature measurement, body temperature distribution, thermal imaging technology, etc., so that the fan can accurately meet the user's needs.
[0009] In one optional implementation, determining the state information based on the body surface temperature distribution information specifically includes: determining the state information as an exercise state based on the rise in the user's facial and limb temperatures based on the body surface temperature distribution information; and determining the state information as a resting state after the exercise has ended based on the return of the facial and limb temperatures to normal within a first preset time.
[0010] Beneficial effects: The rise in body temperature after exercise can be determined through the following examples: The rise in body temperature after exercise is usually systemic, but may be more pronounced in certain areas (such as the face and limbs); the user's thermal image may show a uniform rise in temperature throughout the body or in specific areas; the specific value of the body temperature after exercise can be compared with a preset threshold to determine whether the user is experiencing a rise in body temperature after exercise; the user's movements can also be identified by the camera, such as high-intensity activities like running and brisk walking, to determine whether the user is in a state of exercise and thus infer that they need to dissipate heat quickly.
[0011] In one optional implementation, determining the status information based on the body surface temperature distribution information specifically includes: determining the status information as a sick state if the user's head temperature and chest temperature rise according to the body surface temperature distribution information, and the head temperature and chest temperature remain at a higher level for a second preset time.
[0012] Beneficial effects: When a user is sick, their body temperature usually rises slowly and lasts for a long time, possibly for hours or even days; body temperature may be high at multiple times of the day and not change much; the rise in body temperature due to illness may be systemic, but it may also be more pronounced in certain specific areas (such as the head and chest); moreover, thermal imaging may show abnormally high temperatures in certain specific areas of the user (such as the head and chest).
[0013] In one optional implementation, controlling the fan to start based on the user's status information and executing the working mode corresponding to the status information specifically includes: controlling the fan speed to increase based on the status information being in motion or in a stationary state after motion has ended; or, controlling the fan speed to decrease or controlling the fan to stop based on the status information being in a sick state.
[0014] Beneficial effects: If the user's body surface temperature exceeds a threshold and the user is in motion, the directional precision airflow mode is activated. When the system detects that the user is currently within a comfortable temperature range, it will automatically switch to the broad airflow mode, allowing the user to feel the air more widely and evenly, thus obtaining a more comfortable user experience. Furthermore, the system will continue to monitor the user's status in real time to further enhance user comfort.
[0015] In one optional implementation, the status information includes image information, and obtaining the user's status information specifically includes: obtaining the user's image information; determining the status information based on the image information, wherein the status information includes resting state and reading state.
[0016] Beneficial effects: If the system recognizes that a user is viewing a document or reading a book through image recognition, it will adjust the airflow direction and intensity to avoid interfering with the user's ongoing activity and ensure that the user does not feel uncomfortable due to excessive airflow. The intelligent airflow mode provided in this application embodiment can not only dynamically adjust according to the user's actual needs, but also provide a more personalized and comfortable experience without affecting other activities of the user.
[0017] In one optional implementation, controlling the fan to start based on the user's status information and executing the working mode corresponding to the status information specifically includes: if the status information is a resting state, controlling the fan to reduce the operating level and switching to an oscillating airflow mode after running continuously for a third preset time; or, if the status information is a reading state, adjusting the fan's airflow direction and airflow intensity.
[0018] Beneficial Effects: To better adapt to users' rest needs, the system has a default rest period. During this period, the system will detect whether the user has entered a resting state through image recognition and other means. Once it confirms that the user is resting, the system will slowly reduce the operating level and switch to oscillating fan mode after running for X minutes, providing a gentler and more even airflow, reducing sleep disturbances and ensuring a comfortable environment for the user while sleeping. Furthermore, users can set their own rest period according to their personal habits to further enhance the system's personalized experience.
[0019] In one optional implementation, the control method further includes: acquiring information about the ambient temperature of the user, the distance between the fan and the user, and the user's body temperature changes; and adjusting the fan's operating mode in real time based on the ambient temperature, distance information, and body temperature changes.
[0020] Beneficial Effects: The fan offers five comfort speed settings, categorized by rotation speed as low, medium, and high. Settings 1 and 2 are defined as low speed; 3 as medium speed; and 4 and 5 as high speed. In a test environment of 25℃ and a distance of 2 meters from a person, the most comfortable fan speed is set to the default setting (initial, medium, and 3rd speed). The fan is equipped with an infrared thermal imaging sensor that scans the airflow area, acquiring and detecting ambient temperature, airflow distance, and body temperature. This intelligently determines and adjusts the comfort speed accordingly, truly meeting the user's wind comfort needs at different body temperatures. This allows for more precise control of the fan's operating mode, improving the user experience.
[0021] Secondly, the present invention also provides a fan control device, comprising: a receiving module for receiving a user's request to start the fan; an acquisition module for acquiring the user's status information; and a control module for controlling the fan to start based on the user's status information and executing a working mode corresponding to the status information.
[0022] Thirdly, the present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the fan control method of the first aspect of this application. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0036] The following is combined with Figures 1 to 5 The embodiments of the present invention are described below.
[0037] like Figures 1 to 4 As shown, according to an embodiment of the present invention, in one aspect, the present invention provides a fan control method, the control method comprising: receiving a user's request to start the fan; obtaining the user's status information; controlling the fan to start based on the user's status information, and executing a working mode corresponding to the status information.
[0038] In the above embodiments, the fan control method of this application realizes the different needs of users for air supply mode in multiple states. By intelligently adjusting and controlling the fan, it can accurately match the actual needs of users, thereby improving the user experience and meeting the personalized needs of users.
[0039] Specifically, assuming the fan has three airflow modes, after the fan starts, the system first checks whether the user has enabled the comfort mode. Before the check is complete, it operates at the default speed or setting. Conversely, if the comfort mode is enabled, the system will monitor and obtain the user's current status in real time to dynamically adjust the airflow mode, ensuring that the user is always in the most suitable airflow environment.
[0040] Furthermore, the fan provided in this embodiment of the invention is also equipped with a human body sensor, a human body thermal imaging sensor, and a camera. The human body sensor can detect whether there is a person in the room. When someone enters the room, the fan can automatically adjust the airflow direction and speed according to a preset mode. The human body thermal imaging sensor and the camera can detect the user's status, and the fan can automatically increase the airflow intensity and optimize the airflow direction to achieve better temperature control.
[0041] The fan provided in this embodiment of the invention can intelligently switch its airflow mode based on the user's state: Data acquisition; when the fan is first started, the thermal imaging sensor and camera will perform a comprehensive scan to obtain the initial state of the room. Periodic detection: the system can be set to perform a detection at regular intervals (e.g., every 5 minutes) to update the user's perceived temperature and activity status. Changes in user activity: when the system detects that the user changes from a static state to a moving state, or from a moving state to a static state, it will immediately perform a detection.
[0042] like Figures 1 to 4 As shown, in one optional implementation, the status information includes body temperature information. Obtaining the user's status information specifically includes: obtaining the user's body temperature information; determining the user's body surface temperature distribution information based on the body temperature information; and determining the status information based on the body surface temperature distribution information. The status information includes an exercise state, a resting state after exercise, and an illness state.
[0043] In this embodiment, a user's body surface temperature map is generated using thermal imaging sensor data, creating an image that displays the distribution of the user's body surface temperature. This allows for a direct view of which areas have higher temperatures. If the user's body surface temperature exceeds a certain threshold (e.g., 36°C), it is assumed that the user may require rapid heat dissipation. Furthermore, it is important to distinguish whether the rise in body temperature is caused by illness or exercise. This distinction can be made using methods such as the rate and duration of the temperature rise, the time point of temperature measurement, body temperature distribution, and thermal imaging technology. This ensures that the fan can accurately meet the user's needs.
[0044] Specifically, a user's body temperature usually rises gradually after exercise begins and returns to normal within minutes to half an hour after exercise ends. As for a rise in body temperature caused by illness, the rise is usually slower and lasts longer, possibly for several hours or even days.
[0045] In addition, a user's body temperature rises after exercise, typically appearing higher immediately after exercise but gradually decreasing over time. Conversely, a user's body temperature rises due to illness, with measurements potentially being higher at multiple times of the day and showing little variation. This helps determine whether the rise in body temperature is caused by exercise or illness.
[0046] like Figures 1 to 4 As shown, in some embodiments, determining the state information based on the body surface temperature distribution information specifically includes: determining the state information as an exercise state based on the rise in the user's facial and limb temperatures based on the body surface temperature distribution information; and determining the state information as a static state after the exercise has ended based on the return of the facial and limb temperatures to normal within a first preset time.
[0047] In the above embodiments, the rise in body temperature after exercise can be determined through the following embodiments: the rise in body temperature after exercise is usually systemic, but may be more pronounced in certain areas (such as the face and limbs); the user's thermal image may show a uniform rise in temperature throughout the body or in specific areas; the specific value of the body temperature after exercise can be compared with a preset threshold to determine whether the user is experiencing a rise in body temperature after exercise; the user's actions can also be identified by the camera, such as high-intensity activities like running or brisk walking, to determine whether the user is in a state of exercise and thus infer that they need to dissipate heat quickly.
[0048] Furthermore, facial expressions can be used to determine whether a user is exercising: by analyzing a user's facial expressions, if the user exhibits symptoms such as sweating or facial flushing, it can help determine whether the user needs to dissipate heat quickly. Normally, body temperature gradually rises after exercise begins and gradually returns to normal within a few minutes to half an hour after exercise ends.
[0049] like Figures 1 to 4 As shown, in some embodiments, determining the status information based on the body surface temperature distribution information specifically includes: determining the status information as a sick state based on the rise in the user's head temperature and chest temperature, and the rise in head temperature and chest temperature lasting for a second preset time.
[0050] In the above embodiments, when a user is sick, the rise in body temperature is usually slow and lasts for a long time, possibly for several hours or even days; the body temperature may be high at multiple times of the day and not change much; the rise in body temperature caused by illness may be systemic, but may also be more pronounced in certain specific areas (such as the head and chest); moreover, thermal imaging may show abnormally high temperatures in certain specific areas of the user (such as the head and chest).
[0051] like Figures 1 to 4 As shown, in some embodiments, controlling the fan to start based on the user's status information and executing the working mode corresponding to the status information specifically includes: controlling the fan speed to increase based on the status information being in a moving state or a stationary state after the movement has ended; or, controlling the fan speed to decrease or controlling the fan to stop based on the status information being in a sick state.
[0052] In the above embodiments, if the body surface temperature exceeds a threshold and the user is in motion, the directional precision airflow mode is activated. When the system detects that the user is currently within a comfortable temperature range, it will automatically switch to a broad airflow mode, allowing the user to feel the air more widely and evenly, thus providing a more comfortable user experience. Furthermore, the system will continue to monitor the user's status in real time to further enhance user comfort.
[0053] like Figures 1 to 4 As shown, in some embodiments, the status information includes image information, and obtaining the user's status information specifically includes: obtaining the user's image information; determining the status information based on the image information, wherein the status information includes resting state and reading state.
[0054] In the above embodiments, if the system recognizes that the user is viewing a document or reading a book through image recognition, it will adjust the airflow direction and intensity to avoid interfering with the user's ongoing activity and ensure that the user does not feel uncomfortable due to excessive wind force.
[0055] The intelligent air supply mode provided in this application embodiment can not only be dynamically adjusted according to the user's actual needs, but also provide a more personalized and comfortable experience without affecting the user's other activities.
[0056] like Figures 1 to 4 As shown, in some embodiments, controlling the fan to start based on the user's status information and executing the working mode corresponding to the status information specifically includes: controlling the fan to reduce its operating speed according to the status information being in a resting state, and switching to an oscillating airflow mode after running continuously for a third preset time; or, adjusting the fan's airflow direction and airflow intensity according to the status information being in a reading state.
[0057] In this embodiment, to better accommodate users' rest needs, the system sets a default rest period. During this period, the system will detect whether the user has entered a resting state through image recognition and other means. Once it is confirmed that the user is resting, the system will slowly reduce the operating level and switch to oscillating fan after running for X minutes. This provides a gentler and more even airflow, reducing interference with sleep and ensuring a comfortable environment for the user while sleeping. Furthermore, users can set their own rest period according to their personal habits to further enhance the system's personalized experience.
[0058] Specifically, the fan has a default rest period: the default rest period is from X o'clock in the evening to X o'clock in the morning; users can customize the rest period in the device's settings menu; when the system detects that the user has entered a rest state, it will gradually reduce the operating level; after running continuously for X minutes, the system will automatically switch to oscillating airflow, which can provide a gentler and more even airflow and reduce interference with sleep; this intelligent rest mode can not only dynamically adjust according to the user's actual needs, but also provide a more comfortable and quiet sleep environment without affecting the user's rest.
[0059] like Figures 1 to 4 As shown, in some embodiments, the control method further includes: acquiring the ambient temperature of the user, the distance between the fan and the user, and the user's body temperature change information; and adjusting the fan's operating mode in real time based on the ambient temperature, distance information, and body temperature change information.
[0060] In this embodiment, the fan has five comfort wind speed settings, categorized as low, medium, and high speed based on rotation speed. Settings 1 and 2 are defined as low speed; setting 3 as medium speed; and settings 4 and 5 as high speed. Under experimental conditions of 25°C and a 2m distance from the user, the most comfortable wind speed is set to the default setting, i.e., the initial fan speed (medium speed setting 3). The fan is equipped with an infrared thermal imaging detector that scans the airflow area, acquiring and detecting ambient temperature, airflow distance, and human body temperature. This intelligently determines and adjusts the comfort wind speed to truly meet the user's wind comfort needs at different body temperatures, thereby achieving more precise control of the fan's operating mode and improving the user experience.
[0061] Specifically, the ambient temperature range for fan use is 3℃ to 40℃. Under the experimental environment of 25℃ and a distance of 2m from people, the most comfortable wind speed for the current model is set to the default setting, which is the initial fan speed, medium speed, and speed 3. For every 5℃ increase / decrease, the current speed will be increased / decrease by 1 level.
[0062] The fan operates within an air delivery distance range (0m, 3m). Under experimental conditions of 25℃ and a 2m air delivery distance from a person, the most comfortable wind speed for this model is set to the default setting, which is the initial fan speed, medium speed, or speed 3. For every 1m increase / decrease in air delivery distance, the speed is increased / decreased by 1 level.
[0063] Furthermore, the order of the steps in the above embodiments is only a preferred embodiment of this application. Without conflicting with the inventive concept of this application, the order of the steps can be freely changed, and such adjustments fall within the protection scope of the embodiments of this application.
[0064] like Figure 5As shown, in a second aspect, the present invention also provides a fan control device 10, comprising: a receiving module 11 for receiving a user's request to start the fan; an acquisition module 12 for acquiring the user's status information; and a control module 13 for controlling the fan to start based on the user's status information and executing a working mode corresponding to the status information.
[0065] In the above embodiments, the fan control method of this application realizes the different needs of users for air supply mode in multiple states. By intelligently adjusting and controlling the fan, it can accurately match the actual needs of users, thereby improving the user experience and meeting the personalized needs of users.
[0066] Specifically, assuming the fan has three airflow modes, after the fan starts, the system first checks whether the user has enabled the comfort mode. Before the check is complete, it operates at the default speed or setting. Conversely, if the comfort mode is enabled, the system will monitor and obtain the user's current status in real time to dynamically adjust the airflow mode, ensuring that the user is always in the most suitable airflow environment.
[0067] Thirdly, the present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the fan control method of the first aspect of this application.
[0068] Those skilled in the art will understand that all or part of the processes in the methods of the above embodiments can be implemented by a computer program instructing related hardware.
