Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a control method and a control device for a fan, and a computer-readable storage medium. Background Art

[0002] As people's requirements for the comfort of their living environment increase, different users have different requirements for fan air supply in different environments. In a home environment, users may want a gentle, quiet and directional breeze when sleeping, while they may need a wider and more uniform air supply when relaxing in the living room. Traditional fan air supply methods are often relatively simple and cannot meet such diverse and personalized needs well. From a health perspective, inappropriate air supply methods may have adverse effects on users. For example, users who are directly blown by strong winds for a long time may suffer from muscle stiffness, colds and other problems. Summary of the invention

[0003] In view of this, the present invention provides a method for controlling a fan to solve the technical problem in the prior art that the fan cannot be intelligently adjusted according to the user's status information.

[0004] In a first aspect, the present invention provides a method for controlling a fan, the method comprising: receiving a request from a user to start the fan; obtaining status information of the user; and based on the status information of the user, controlling the fan to start and executing a working mode corresponding to the status information.

[0005] Beneficial effect: The fan control method of the present invention realizes the different needs of users for air supply modes in multiple states, and 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 that the fan has three air supply modes, after the fan is started, the fan system first detects whether the user has enabled the comfort wind function, and executes at the default speed or gear before the detection is completed. On the contrary, if the comfort wind function is enabled, the system will monitor and obtain the user's current status information in real time to dynamically adjust the air supply mode to ensure that the user is always in the most suitable air supply environment.

[0007] In an optional embodiment, the status information includes body temperature information, and 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; determining the status information based on the body surface temperature distribution information, wherein the status information includes motion status, static state after motion, and sick state.

[0008] Beneficial effects: The user's body surface temperature map is generated through thermal imaging sensor data, and an image showing the user's body surface temperature distribution is generated. You can intuitively see which parts have higher temperatures. If the user's body surface temperature exceeds a certain threshold (for example, 36°C), it is considered that the user may need to dissipate heat quickly. In addition, it is necessary to distinguish whether the rise in human body temperature is caused by illness or exercise. The speed and duration of the temperature rise, the time point of temperature measurement, temperature distribution, thermal imaging technology and other methods can be used to distinguish, so that the fan can accurately meet the needs of users.

[0009] In an optional embodiment, determining the status information based on the body surface temperature distribution information specifically includes: determining that the status information is a motion state based on the body surface temperature distribution information that the user's facial temperature and limb temperature rise; and determining that the status information is a static state after the end of exercise based on the facial temperature and limb temperature returning to normal within a first preset time.

[0010] Beneficial effects: The rise in body temperature after exercise can be determined by the following embodiments: the rise in body temperature after exercise is usually systemic, but may be more obvious in certain parts (such as the face and limbs); the user's thermal imaging image may show a uniform temperature rise throughout the body or in specific parts; the specific value of the body temperature after exercise can be used to compare with a preset threshold to determine whether the user is in a state of body temperature rise after exercise; the user's movements can also be recognized by the camera, such as high-intensity activities such as running and brisk walking, to determine whether the user is in a state of exercise, thereby inferring that he needs to dissipate heat quickly.

[0011] In an optional embodiment, determining the status information according to the body surface temperature distribution information specifically includes: according to the body surface temperature distribution information, if the head temperature and chest temperature of the user rise, and the head temperature and chest temperature continue for a second preset time after rising, determining the status information as an illness state.

[0012] Beneficial effects: When a user is sick, the temperature rise is usually slow and lasts for a long time, possibly for hours or even days; the temperature may be high when measured at multiple time points throughout the day and may not change much; the temperature rise caused by illness may be systemic, but may also be more obvious in certain specific areas (such as the head and chest); and thermal imaging may show abnormally high temperatures in certain specific areas of the user (such as the head and chest).

[0013] In an optional embodiment, based on the user's status information, the fan is controlled to start, and the working mode corresponding to the status information is executed, specifically including: according to the status information being a motion state or a stationary state after exercise, the fan speed is controlled to increase; or, according to the status information being an illness state, the fan speed is controlled to decrease, or the fan is controlled to stop.

[0014] Beneficial effects: If the user's body temperature exceeds the threshold and the user is in motion, the directional precision air supply mode is activated; when the system detects that the user is currently in a comfortable temperature range, it will automatically switch to the wide air supply mode, allowing the user to feel the wind more widely and evenly, thereby obtaining a more comfortable user experience. On this basis, the system will continue to monitor the user's status in real time to further improve the user's comfort.

[0015] In an optional implementation, the status information includes image information, and obtaining the status information of the user specifically includes: obtaining the image information of the user; and determining the status information according to the image information, wherein the status information includes a resting state and a reading state.

[0016] Beneficial effect: If the system detects through image recognition that the user is viewing a document or reading a book, it will adjust the air supply direction and intensity to avoid interfering with the user's ongoing activities and ensure that the user does not feel uncomfortable due to excessive wind. The intelligent air supply mode provided in the embodiment of the present application can not only be dynamically adjusted according to the actual needs of the user, but also provide a more personalized comfort experience without affecting other activities of the user.

[0017] In an optional embodiment, based on the user's status information, the fan is controlled to start, and the working mode corresponding to the status information is executed, specifically including: according to the status information being a resting state, the fan is controlled to lower the operating gear, and after running continuously for a third preset time, it is switched to a shaking air supply mode; or, according to the status information being a reading state, the air supply direction and air supply intensity of the fan are adjusted.

[0018] Beneficial effects: In order to better meet the user's rest needs, the system sets a default rest time 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 gear and switch to shaking the air supply after running continuously for X minutes, which can provide a softer and more uniform airflow, reduce the interference mode to sleep, and ensure that the user enjoys a comfortable environment while sleeping. In addition, users can set the rest time period according to their personal habits to further enhance the personalized experience of the system.

[0019] In an optional implementation, the control method further includes: obtaining the ambient temperature of the user, the distance information between the fan and the user, and the user's body temperature change information; and adjusting the fan's operating mode in real time according to the ambient temperature, distance information, and body temperature change information.

[0020] Beneficial effect: The fan has 5 comfortable wind gears, which are divided into low speed, medium speed and high speed according to the speed. Gears 1 and 2 are defined as low speed; gear 3 is defined as medium speed; gears 4 and 5 are defined as high speed. Under the experimental environment of 25℃ and the air supply distance of 2m from people, the most comfortable wind speed of the current model is set to the default gear, that is, the fan's initial gear is medium speed gear 3. The fan is equipped with an infrared thermal imaging detector, which scans the fan's air supply area at the same time, obtains and detects the ambient temperature, air supply distance and human body temperature, and intelligently determines and adjusts the execution of the comfortable wind supply gear, truly meeting the wind feeling needs of users in different body temperature states, so as to achieve the purpose of further accurately controlling the fan's working mode and improving the user's experience.

[0021] In a second aspect, 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] In a third aspect, the present invention further provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the fan control method of the first aspect of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the 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 creative work are within the scope of protection of the present invention.

[0035] In addition, 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] Combine the following Figures 1 to 5 , describing embodiments of the present invention.

[0037] like Figures 1 to 4 As shown, according to an embodiment of the present invention, on the one hand, the present invention provides a method for controlling a fan, the control method comprising: receiving a user's request to start the fan; obtaining the user's status information; based on the user's status information, controlling the fan to start, and executing a working mode corresponding to the status information.

[0038] In the above embodiments, the fan control method of the embodiment of the present application realizes the user's different needs for air supply modes in multiple states, and through intelligent adjustment and control of the fan, it can accurately match the user's actual needs, thereby improving the user's usage experience and meeting the user's personalized needs.

[0039] Specifically, assuming that the fan has three air supply modes, after the fan is started, the fan system first detects whether the user has enabled the comfort wind function, and executes at the default speed or gear before the detection is completed. Conversely, if the comfort wind function is enabled, the system will monitor and obtain the user's current status in real time to dynamically adjust the air supply mode to ensure that the user is always in the most suitable air supply environment.

[0040] Furthermore, the fan provided in the embodiment of the present invention is also provided with a human body sensing sensor, a human body thermal imaging sensor and a camera. The human body sensing sensor can detect whether there is someone in the room. When someone enters the room, the fan can automatically adjust the air supply direction and wind speed according to a pre-set mode; the human body thermal imaging sensor and the camera can detect the user status, and the fan can automatically enhance the air supply wind intensity and optimize the air supply direction to achieve a better temperature control effect.

[0041] The fan provided by the embodiment of the present invention can intelligently switch the air supply mode by judging the user's status: data collection: when the fan is started for the first time, the thermal imaging sensor and the camera will perform a comprehensive scan to obtain the initial state of the room. Regular detection: the system can be set to perform a detection at regular intervals (for example, every 5 minutes) to update the user's body temperature and activity status. When the user's activity changes: when the system detects that the user changes from a stationary state to a moving state, or from a moving state to a stationary state, a detection will be performed immediately.

[0042] like Figures 1 to 4 As shown, in an optional embodiment, the status information includes body temperature information, and 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; determining the status information based on the body surface temperature distribution information, wherein the status information includes motion status, static state after motion, and sick state.

[0043] In this embodiment, a user's body surface temperature map is generated through thermal imaging sensor data, and an image showing the user's body surface temperature distribution is generated, so that you can intuitively see which parts have higher temperatures. If the user's body surface temperature exceeds a certain threshold (for example, 36°C), it is considered that the user may need to dissipate heat quickly. In addition, it is necessary to distinguish whether the rise in human body temperature is caused by illness or exercise. The distinction can be made through methods such as the speed and duration of temperature rise, the time point of temperature measurement, temperature distribution, and thermal imaging technology, so that the fan can accurately meet user needs.

[0044] Specifically, the user's body temperature will usually rise gradually after the start of exercise, and will gradually return to normal within a few minutes to half an hour after the exercise. As for the temperature rise caused by the user's illness, the temperature rise is usually slow and lasts for a long time, which may last for several hours or even days.

[0045] In addition, the body temperature of the user rises after exercise. The body temperature is usually higher when measured immediately after the user exercises, but it will gradually decrease over time. The body temperature of the user rises due to illness. The user's body temperature may be higher at multiple times of the day and change little, so as to determine whether the user's body temperature rise 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 that the state information is a motion state based on the body surface temperature distribution information that the user's facial temperature and limb temperature rise; and determining that the state information is a static state after the end of exercise based on the facial temperature and limb temperature returning to normal within a first preset time.

[0047] In the above embodiment, the temperature rise after exercise can be determined by the following embodiments: the temperature rise after exercise is usually systemic, but may be more obvious in certain parts (such as the face and limbs); the user's thermal imaging image may show a uniform temperature rise throughout the body or in specific parts; the specific value of the body temperature after exercise can be used to compare with a preset threshold to determine whether the user is in a state of temperature rise after exercise; the user's movements can also be recognized by the camera, such as high-intensity activities such as running and brisk walking, to determine whether the user is in a state of exercise, thereby inferring that he needs to dissipate heat quickly.

[0048] Furthermore, facial expressions can be used to determine whether the user is exercising: by analyzing the user's facial expressions, if the user shows symptoms such as sweating and facial flushing, it can also assist in determining whether the user needs to dissipate heat quickly. Usually, body temperature will gradually rise after exercise begins, and will gradually return 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: according to the body surface temperature distribution information, if the head temperature and chest temperature of the user rise, and the head temperature and chest temperature continue for a second preset time after rising, determining the status information as an illness state.

[0050] In the above embodiments, the temperature rise of the user when he is sick is usually slow and lasts for a long time, which may last for several hours or even several days; the body temperature measured at multiple time points in a day may be high and change little; the temperature rise caused by illness may be systemic, but it may also be more obvious in certain specific areas (such as the head and chest); and the thermal imaging image may show that the temperature of certain specific areas of the user (such as the head and chest) is abnormally increased.

[0051] like Figures 1 to 4 As shown, in some embodiments, based on the user's status information, the fan is controlled to start, and the working mode corresponding to the status information is executed, specifically including: according to the status information being a motion state or a stationary state after motion, the fan speed is controlled to increase; or, according to the status information being an illness state, the fan speed is controlled to decrease, or the fan is controlled to stop.

[0052] In the above embodiment, if the body surface temperature exceeds the threshold and the user is in motion, the directional precision air supply mode is activated. When the system detects that the user is currently in a comfortable temperature range, it will automatically switch to the wide air supply mode, allowing the user to feel the wind more widely and evenly, so that the user can have a more comfortable use experience. On this basis, the system will continue to monitor the user's status in real time to further improve the user's comfort.

[0053] like Figures 1 to 4 As shown, in some embodiments, the status information includes image information, and obtaining the status information of the user specifically includes: obtaining the image information of the user; and determining the status information according to the image information, wherein the status information includes a resting state and a reading state.

[0054] In the above embodiment, if it is detected through image recognition that the user is viewing a document or reading a book, the system will adjust the air supply direction and intensity to avoid interfering with the user's ongoing activities and ensure that the user does not feel uncomfortable due to excessive wind.

[0055] The intelligent air supply mode provided in the embodiment of the present application can not only be dynamically adjusted according to the actual needs of the user, but also provide a more personalized comfort experience without affecting other activities of the user.

[0056] like Figures 1 to 4 As shown, in some embodiments, based on the user's status information, the fan is controlled to start, and the working mode corresponding to the status information is executed, specifically including: according to the status information being a rest state, the fan is controlled to lower the operating gear, and after running continuously for a third preset time, it is switched to the shaking air supply mode; or, according to the status information being a reading state, the air supply direction and air supply intensity of the fan are adjusted.

[0057] In this embodiment, in order to better meet the user's rest needs, the system sets a default rest time 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 gear and switch to shaking the wind after running continuously for X minutes, which can provide a softer and more uniform airflow, reduce the interference mode to sleep, and ensure that the user enjoys a comfortable environment while sleeping. In addition, users can set the rest time period according to their personal habits to further enhance the personalized experience of the system.

[0058] Specifically, the fan sets a default rest time period: the default rest time period is from X o'clock in the evening to X o'clock in the morning; users can customize the rest time 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 gear; after running continuously for X minutes, the system will automatically switch to shaking head air supply, which can provide a softer and more even airflow, reducing interference with sleep; this intelligent rest mode can not only be dynamically adjusted according to the actual needs of the user, but also provide a more comfortable and quiet sleeping environment without affecting the user's rest.

[0059] like Figures 1 to 4 As shown, in some embodiments, the control method also includes: obtaining the ambient temperature of the user, the distance information between the fan and the user, and the user's body temperature change information; and adjusting the fan's working mode in real time according to the ambient temperature, distance information, and body temperature change information.

[0060] In this embodiment, the fan has 5 comfortable wind gears, which are divided into low speed gear, medium speed gear and high speed gear according to the rotation speed. Gears 1 and 2 are defined as low speed gear; gear 3 is defined as medium speed gear; gears 4 and 5 are defined as high speed gear. Under the experimental environment of 25℃ and the air supply distance of 2m from the person, the most comfortable wind speed of the current model is set to the default gear, that is, the fan initial gear medium speed gear 3. The fan is equipped with an infrared thermal imaging detector, which scans the air supply area of ​​the fan at the same time, obtains and detects the ambient temperature, air supply distance and human body temperature, and intelligently determines and adjusts the execution of the comfortable wind supply gear, which truly meets the wind feeling requirements of the user's body in different temperature states, so as to achieve the purpose of further accurately controlling the working mode of the fan and improve the user's experience.

[0061] Specifically, the ambient temperature range of the fan is (3℃, 40℃). For the current model, under the experimental environment of 25℃ and the air supply distance of 2m from people, the most comfortable wind speed is set to the default gear, that is, the fan's initial gear is medium speed gear 3. For every increase / decrease of 5℃, the current gear is increased / decreased by 1 gear.

[0062] The fan uses an air supply distance range of (0m, 3m). For the current model, under the experimental environment of 25°C and an air supply distance of 2m from a person, the most comfortable wind speed is set to the default gear, that is, the fan's initial gear is medium speed gear 3. For every increase / decrease of 1m in the air supply distance, the current gear is increased / decreased by 1 gear.

[0063] In addition, the order of the steps in the above embodiments is only a preferred embodiment of the present application. Without conflicting with the inventive concept of the present application, the order of the steps can be freely changed, and such adjustment falls within the protection scope of the embodiments of the present application.

[0064] like Figure 5As shown, in the second aspect, the present invention also provides a fan control device 10, including: a receiving module 11, used to receive a user's request to start the fan; an acquisition module 12, used to obtain the user's status information; a control module 13, used to control the fan to start based on the user's status information, and execute a working mode corresponding to the status information.

[0065] In the above embodiments, the fan control method of the embodiment of the present application realizes the user's different needs for air supply modes in multiple states, and through intelligent adjustment and control of the fan, it can accurately match the user's actual needs, thereby improving the user's usage experience and meeting the user's personalized needs.

[0066] Specifically, assuming that the fan has three air supply modes, after the fan is started, the fan system first detects whether the user has enabled the comfort wind function, and executes at the default speed or gear before the detection is completed. Conversely, if the comfort wind function is enabled, the system will monitor and obtain the user's current status in real time to dynamically adjust the air supply mode to ensure that the user is always in the most suitable air supply environment.

[0067] In a third aspect, the present invention further provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the fan control method of the first aspect of the present application.
