Description

Technical Field

[0001] This invention relates to the field of air conditioner control technology, and in particular to an automatic control method for air conditioners. Background Technology

[0002] With the continuous improvement of technology and people's living standards, smart home appliances are constantly developing, and smart ecosystems are gradually becoming an important indicator for people to choose home appliances. The popularization of smart home appliances is closely related to the interaction with mobile phones, bringing convenience and efficiency improvements to users. At present, air conditioning control systems are characterized by unintelligent control modes, inconvenient control methods, and single control approaches. Some air conditioners on the market with automatic control functions often simply determine the corresponding cooling or heating mode based on the ambient temperature. The logic of the automatic control method is simple and difficult to adapt to the growing intelligent needs of users. At the same time, this kind of automatic control function does not consider the user's comfort needs, resulting in a poor user experience. Summary of the Invention

[0003] To address the aforementioned shortcomings, the present invention aims to propose an automatic control method for air conditioners. This method aims to achieve intelligent control of the air conditioner by comprehensively analyzing the user's physiological state information, personal characteristic information, and indoor environmental information, thereby enabling the selection of the air conditioner's operating mode and personalized adjustment of its parameters, thus providing users with a more comfortable experience.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] An automatic control method for an air conditioner includes the following steps:

[0006] S1: Identify the user's identity and obtain the user's physiological status information and personal characteristic information. The physiological status information includes heart rate, and the personal characteristic information includes age, gender, height, and weight.

[0007] S2: Collect environmental information of the room where the air conditioner is located, including temperature and humidity values;

[0008] S3: Controls the start and stop of the air conditioner's operating mode based on physiological and environmental information, and adjusts the operating parameters of the operating mode based on the user's personal characteristics.

[0009] S4: If the user actively adjusts the operating mode and operating parameters of the air conditioner after step S3, the operating mode and operating parameters under the current physiological state information, personal characteristic information and environmental information are recorded, and the air conditioner is controlled the next time the user uses it.

[0010] S5: After each preset first time interval, obtain the user's perceived comfort level through each user's historical usage records, and adjust the cooling capacity of the air conditioner based on the perceived comfort level of one or more users in the room where the air conditioner is located.

[0011] Preferably, in step S3, controlling the start and stop of the air conditioner's operating mode based on physiological state information and environmental information includes:

[0012] If the temperature value is outside the preset comfortable temperature range, the air conditioner will be controlled to turn on the temperature adjustment mode to adjust the indoor temperature until the temperature value is within the preset comfortable temperature range, at which point the temperature adjustment mode will be stopped.

[0013] If the humidity value is outside the preset comfortable humidity range, the air conditioner will be controlled to turn on the humidity adjustment mode to adjust the indoor humidity until the humidity value is within the preset comfortable humidity range, at which point the humidity adjustment mode will be stopped.

[0014] If the user's heart rate is higher than the preset normal heart rate range, the temperature adjustment mode will be activated first when both the temperature and humidity values ​​are not within the comfortable range. If the user's heart rate is lower than the preset normal heart rate range, the humidity adjustment mode will be activated first when both the temperature and humidity values ​​are not within the comfortable range.

[0015] Furthermore, in step S3, adjusting the operating parameters of the operating mode based on the user's personal characteristic information includes the following steps:

[0016] S310: Obtain reference age and corresponding comfortable temperature range;

[0017] S311: Based on the aforementioned comfortable temperature range, calculate the upper and lower limits of the user's comfortable temperature range according to the difference between the user's age and the reference age, and satisfy the following relationship:

[0018]

[0019] Where T represents the upper or lower limit of the comfort temperature range, T′ represents the upper or lower limit of the adjusted comfort temperature range, and k 温 a represents the temperature regulation coefficient. 用 Indicates the user's age, a 参 Indicates a reference age;

[0020] S312: Control the air conditioner's operating temperature adjustment mode to adjust the indoor temperature to the comfortable temperature range calculated in step S311.

[0021] Furthermore, in step S3, adjusting the operating parameters of the operating mode based on the user's personal characteristic information includes the following steps:

[0022] S320: Obtain reference age and corresponding comfortable humidity range;

[0023] S321: Based on the aforementioned comfortable humidity range, calculate the upper and lower limits of the user's comfortable humidity range according to the difference between the user's age and a reference age, and satisfy the following relationship:

[0024]

[0025] Where H represents the upper or lower limit of the comfortable humidity range, H′ represents the upper or lower limit of the adjusted comfortable humidity range, and k 湿 Indicates the humidity regulation coefficient, a 用 Indicates the user's age, a 参 Indicates a reference age;

[0026] S322: Control the air conditioner to operate in humidity adjustment mode, and adjust the indoor humidity value to the comfortable humidity range calculated in step S321.

[0027] Furthermore, in step S3, adjusting the operating parameters of the operating mode based on the user's personal characteristic information includes the following steps:

[0028] S331: Get the current season information;

[0029] S332: If the current season is spring or summer, then the comfortable temperature range is adjusted according to the user's gender, and the following relationship is satisfied:

[0030] T′=T+k 性 +s1;

[0031] Where T represents the upper or lower limit of the comfort temperature range, T′ represents the upper or lower limit of the adjusted comfort temperature range, and k 性 s1 represents the gender adjustment coefficient, and s1 represents the adjustment coefficient for spring or summer.

[0032] S333: If the current season is autumn or winter, the comfortable temperature range is adjusted according to the user's gender, and the following relationship is satisfied:

[0033] T′=T+k 性 -s2;

[0034] Where T represents the upper or lower limit of the comfort temperature range, T′ represents the upper or lower limit of the adjusted comfort temperature range, and k 性 s1 represents the sex adjustment coefficient, and s2 represents the adjustment coefficient for autumn or winter.

[0035] S334: Control the air conditioner's operating temperature adjustment mode to adjust the indoor temperature to the comfortable temperature range calculated in step S333.

[0036] Preferably, in step S3, adjusting the operating parameters of the operating mode based on the user's personal characteristic information includes the following steps:

[0037] Calculate the user's BMI data based on their height and weight;

[0038] If the user's BMI data is within the underweight range, then determine whether the user's heart rate is within the preset normal heart rate range. If so, adjust the air conditioner's fan speed to the second level. If the user's heart rate is higher than the normal heart rate range, adjust the air conditioner's fan speed to the third level. If the user's heart rate is lower than the normal heart rate range, adjust the air conditioner's fan speed to the first level.

[0039] If the user's BMI data is within the normal range, then determine whether the user's heart rate is within the preset normal heart rate range. If so, adjust the air conditioner's fan speed to the third level. If the user's heart rate is higher than the normal heart rate range, adjust the air conditioner's fan speed to the fourth level. If the user's heart rate is lower than the normal heart rate range, adjust the air conditioner's fan speed to the second level.

[0040] If the user's BMI is within the obese range, the system determines whether the user's heart rate is within the preset normal heart rate range. If so, the air conditioner's fan speed is adjusted to the fourth level. If the user's heart rate is higher than the normal heart rate range, the air conditioner's fan speed is adjusted to the fifth level. If the user's heart rate is lower than the normal heart rate range, the air conditioner's fan speed is adjusted to the third level.

[0041] Preferably, step S3 further includes identifying the user's level of perspiration;

[0042] If the user is slightly sweating or not sweating, adjust the angle between the air conditioner's airflow direction and the user to within the first angle range;

[0043] If the user is in a state of moderate sweating, adjust the angle between the air conditioner's air outlet direction and the user to within the second angle range;

[0044] If the user is sweating profusely, adjust the angle between the air conditioner's airflow direction and the user to within the third angle range;

[0045] Among them, the lower limit of the first included angle range is greater than the upper limit of the second included angle range, and the lower limit of the second included angle range is greater than the upper limit of the third included angle range.

[0046] Preferably, in step S4, if the user actively adjusts the operating mode and operating parameters of the air conditioner within a preset second time interval after step S3, the historical operating mode and historical operating parameters under the current physiological state information, personal characteristic information and environmental information are recorded.

[0047] The next time a user uses the air conditioner, they will control it using the same historical operating mode and parameters based on the same physiological state information, personal characteristic information, or environmental information.

[0048] Preferably, the environmental information also includes the space capacity of the room where the air conditioner is located;

[0049] Step S5 includes the following steps:

[0050] S51: Obtain the current user's perceived comfort level in the current environment from historical usage records;

[0051] S52: If the acquisition fails, combine the historical usage records of other users on the air conditioner under the current environmental information to determine the current user's perceived comfort level under the current environmental information.

[0052] S53: Adjust the cooling capacity of the air conditioner according to the indoor space capacity and the user's physiological state information to make the user feel comfortable under the current environmental information.

[0053] S54: After each preset first time interval, obtain the current environmental information. If the environmental information changes, execute steps S51-S53 to maintain the user's physical comfort.

[0054] Furthermore, in step S5, if there are two people in the room where the air conditioner is located:

[0055] Determine if the comfort levels of the two individuals are similar. If they are similar, adjust the cooling capacity of the air conditioner to meet the comfort level of one of them.

[0056] If they are not similar, adjust the cooling capacity of the air conditioner to adjust the user's perceived comfort to the middle value of the perceived comfort of the two.

[0057] If there are two or more people in the room where the air conditioner is located:

[0058] If multiple people have similar levels of comfort, the cooling capacity of the air conditioner is adjusted in the third time interval to meet the comfort level of the multiple people. In the fourth time interval, the cooling capacity of the air conditioner is adjusted to adjust the user's comfort level to the maximum or minimum value among the multiple people's comfort levels.

[0059] If multiple users do not have similar levels of comfort, the cooling capacity of the air conditioner should be adjusted to a value that is the median of the maximum and minimum levels of comfort among the multiple users.

[0060] One of the above technical solutions has the following advantages or beneficial effects:

[0061] This solution, by recognizing users' physiological state and personal characteristics, can more accurately understand their comfort needs, further refine adjustment strategies, and provide a personalized comfort experience. It can automatically start, stop, and adjust the air conditioner's operating mode based on real-time environmental information, avoiding unnecessary energy waste. Simultaneously, by personalized adjustment of operating parameters, it ensures that user comfort needs are met while minimizing energy consumption, achieving energy conservation and environmental protection goals. Furthermore, the air conditioner has learning capabilities, recording users' proactive adjustments to the air conditioner's operating mode and parameters, and continuously optimizing its control strategy accordingly. With increased usage time, the air conditioner will better understand user preferences and habits, thus providing more considerate and efficient service. By adjusting the cooling capacity based on feedback from historical usage records, it can promptly adjust the cooling capacity to meet the needs of all users. Attached Figure Description

[0068] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0069] In this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0070] With the continuous improvement of technology and people's living standards, smart home appliances are constantly developing, and smart ecosystems are gradually becoming an important indicator for people to choose home appliances. The popularization of smart home appliances is closely related to the interaction with mobile phones, bringing convenience and efficiency improvements to users. At present, air conditioning control systems are characterized by unintelligent control modes, inconvenient control methods, and single control approaches. Some air conditioners on the market with automatic control functions often simply determine the corresponding cooling or heating mode based on the ambient temperature. The logic of the automatic control method is simple and difficult to adapt to the growing intelligent needs of users. At the same time, this kind of automatic control function does not consider the user's comfort needs, resulting in a poor user experience.

[0071] Therefore, an automatic control method for air conditioners is proposed, such as... Figure 1 As shown, a preferred embodiment of this application includes the following steps:

[0072] S1: Identify the user's identity and obtain the user's physiological status information and personal characteristic information. The physiological status information includes heart rate, and the personal characteristic information includes age, gender, height, and weight.

[0073] In this step, personal characteristic information can be pre-input or recorded by the user, while physiological state information is collected in real time. In this embodiment, a fingerprint unlocking module or a facial recognition module can be set on the remote control corresponding to the air conditioner. The remote control obtains the user's personal characteristic information through fingerprint unlocking, such as the user's basic information, including age, gender, height, weight, etc. A physiological state collection module can also be set on the remote control to collect the user's physiological state information, including but not limited to the user's heart rate, body temperature, blood pressure, and other physiological indicators. User identification ensures the accuracy and personalization of the information. For example, a family may have multiple users, each with different needs and preferences, requiring differentiation when adjusting the air conditioner. Obtaining physiological state information allows for real-time understanding of the user's health status, enabling corresponding adjustments. If the user is exercising or feeling hot, the air conditioner may need to lower the indoor temperature more quickly. Based on personal characteristic information such as the user's age and gender, the user's comfort range for temperature can be determined. For example, women and men may have different comfort needs under the same environmental conditions.

[0074] S2: Collect environmental information of the room where the air conditioner is located, including temperature and humidity values;

[0075] In this step, temperature and humidity sensors can be installed inside the air conditioner to measure the temperature and humidity values ​​of the room where the air conditioner is located. Collecting environmental information allows for real-time understanding of the indoor environment, assisting in the intelligent adjustment of the air conditioner. Temperature and humidity data are used to determine whether the current environment requires a change in operating mode.

[0076] S3: Controls the start and stop of the air conditioner's operating mode based on physiological and environmental information, and adjusts the operating parameters of the operating mode based on the user's personal characteristics.

[0077] Specifically, air conditioners can operate in modes such as temperature control, humidity control, energy saving, and sleep mode. When physiological states and environmental information change, the air conditioner needs to adjust accordingly. The air conditioner needs to activate or deactivate a mode to begin or end its adjustment. For example, if the ambient temperature is higher than the comfortable indoor temperature range, the air conditioner needs to activate the temperature control mode. When determining the air conditioner's operating mode, the operating parameters need to be adjusted based on the user's individual characteristics. For instance, when setting the temperature, users of different ages have different temperature perception abilities, so different comfortable temperature ranges need to be set for different age groups. Additionally, older users may suffer from rheumatic symptoms, so the air conditioner needs to control the indoor humidity to a lower level. It's worth noting that when a user enters the room after exercising outdoors or exercises indoors, if the user's heart rate is high or they are sweating, the air conditioner's airflow speed or direction can be adjusted to improve the user experience.

[0078] S4: If the user actively adjusts the operating mode and operating parameters of the air conditioner after step S3, the operating mode and operating parameters under the current physiological state information, personal characteristic information and environmental information are recorded, and the air conditioner is controlled the next time the user uses it.

[0079] After the air conditioner is set to automatic control, the user may need to control it again due to experience issues or physical discomfort. The user's adjustment of the operating parameters is the most suitable for that user. Therefore, by recording this adjustment, the specific operating mode (such as cooling or heating) and its set values ​​(such as temperature and fan speed) selected by the user can be recorded. When a user of the same age, height, or weight uses the air conditioner at the same temperature, the air conditioner can directly adjust the operating mode and operating parameters based on the record, reducing the need for manual adjustment by the user while providing a personalized comfort experience.

[0080] S5: After each preset first time interval, obtain the user's perceived comfort level through each user's historical usage records, and adjust the cooling capacity of the air conditioner based on the perceived comfort level of one or more users in the room where the air conditioner is located.

[0081] After a user adjusts the air conditioner or the air conditioner automatically adjusts its operating mode and parameters, if the user does not continue to adjust them within a certain period, the air conditioner considers the current operating mode and parameters to meet the user's needs. The air conditioner records the user's air conditioning settings and operating modes under different environmental conditions. The air conditioner dynamically adjusts its cooling capacity based on real-time environmental information (temperature, humidity) and the user's perceived comfort. For example, when the ambient temperature rises and the user reports sweating, the air conditioner will automatically increase the cooling capacity. Since there may be multiple users in the space where the air conditioner is located, it is necessary to dynamically adjust the air conditioner's cooling capacity based on the perceived comfort of multiple users to meet the needs of all users as much as possible.

[0082] Preferably, in step S3, controlling the start and stop of the air conditioner's operating mode based on physiological state information and environmental information includes:

[0083] If the temperature value is outside the preset comfortable temperature range, the air conditioner will be controlled to turn on the temperature adjustment mode to adjust the indoor temperature until the temperature value is within the preset comfortable temperature range, at which point the temperature adjustment mode will be stopped.

[0084] If the humidity value is outside the preset comfortable humidity range, the air conditioner will be controlled to turn on the humidity adjustment mode to adjust the indoor humidity until the humidity value is within the preset comfortable humidity range, at which point the humidity adjustment mode will be stopped.

[0085] If the user's heart rate is higher than the preset normal heart rate range, the temperature adjustment mode will be activated first when both the temperature and humidity values ​​are not within the comfortable range. If the user's heart rate is lower than the preset normal heart rate range, the humidity adjustment mode will be activated first when both the temperature and humidity values ​​are not within the comfortable range.

[0086] Specifically, the comfortable temperature range needs to be set based on multiple factors. This range can be determined according to the season, environmental factors, and the user's health condition. Initially, when using the air conditioner, the indoor temperature is controlled within a generally acceptable comfortable temperature range. This range can be adjusted later based on the user's individual needs. If the indoor temperature is outside the preset comfortable temperature range, the air conditioner needs to activate the temperature control mode to adjust the indoor temperature. Once the temperature is within the preset comfortable temperature range, temperature control stops. Similarly, if the indoor humidity is outside the preset comfortable humidity range, the air conditioner needs to activate the humidity control mode to adjust the indoor humidity. Once the humidity is within the preset comfortable humidity range, humidity control stops.

[0087] It's worth noting that when a user's heart rate exceeds the preset normal heart rate range, it usually indicates that the body may be under considerable stress or high pressure. In this situation, temperature regulation becomes particularly important because the body generates more heat during exercise or stress. If the ambient temperature is too high or too low, it will further exacerbate the body's thermal load or cold stress, thus affecting heart rate and overall health. In high-temperature environments, the body activates a series of physiological mechanisms to dissipate heat, such as sweating and increasing skin blood flow. These processes increase the burden on the heart, leading to an increased heart rate. Therefore, lowering the ambient temperature is an effective way to alleviate this burden. When the heart rate is already high, prioritizing the activation of the temperature regulation mode can help the body return to a suitable temperature range more quickly, thereby reducing the burden on the heart and lowering the heart rate.

[0088] In high-humidity environments, the body's heat dissipation efficiency decreases, leading to feelings of stuffiness and discomfort. This discomfort can affect a user's mood and overall health, indirectly impacting heart rate. Reducing ambient humidity can improve the body's heat dissipation efficiency, making people feel cooler and more comfortable. When heart rate is high, priority is given to temperature regulation to reduce the burden on the heart; when heart rate is low, priority is given to humidity regulation to enhance comfort and health. This helps to better meet users' individual needs and improve the user experience.

[0089] In another embodiment, in step S3, as Figure 2 As shown, adjusting the operating parameters of the operating mode based on the user's personal characteristics includes the following steps:

[0090] S310: Obtain reference age and corresponding comfortable temperature range;

[0091] S311: Based on the aforementioned comfortable temperature range, calculate the upper and lower limits of the user's comfortable temperature range according to the difference between the user's age and the reference age, and satisfy the following relationship:

[0092]

[0093] Where T represents the upper or lower limit of the comfort temperature range, T′ represents the upper or lower limit of the adjusted comfort temperature range, and k 温 a represents the temperature regulation coefficient. 用 Indicates the user's age, a 参 Indicates a reference age;

[0094] S312: Control the air conditioner's operating temperature adjustment mode to adjust the indoor temperature to the comfortable temperature range calculated in step S311.

[0095] Specifically, different ages have different sensitivities and perceptions of temperature. Therefore, in step S310, a baseline age (reference age) is first determined. This reference age needs to be representative and reflect the general temperature preferences of most people in that age group, such as 30 years old. A standard comfortable temperature range is then set for this age, such as 20-22℃. When the user is 40 years old, the temperature adjustment coefficient k... 温 The value is 1, therefore the user's comfortable temperature range is 20.45-22.45℃. The air conditioner then turns on its temperature control mode to adjust the indoor temperature to between 20.45-22.45℃. The temperature control coefficient k is 1. 温 It can be adjusted according to factors such as season or environment.

[0096] In step S3, as Figure 3 As shown, adjusting the operating parameters of the operating mode based on the user's personal characteristics includes the following steps:

[0097] S320: Obtain reference age and corresponding comfortable humidity range;

[0098] S321: Based on the aforementioned comfortable humidity range, calculate the upper and lower limits of the user's comfortable humidity range according to the difference between the user's age and a reference age, and satisfy the following relationship:

[0099]

[0100] Where H represents the upper or lower limit of the comfortable humidity range, H′ represents the upper or lower limit of the adjusted comfortable humidity range, and k 湿 Indicates the humidity regulation coefficient, a 用 Indicates the user's age, a 参 Indicates a reference age;

[0101] S322: Control the air conditioner to operate in humidity adjustment mode, and adjust the indoor humidity value to the comfortable humidity range calculated in step S321.

[0102] Specifically, people of different ages experience indoor humidity differently. For example, older users may suffer from rheumatism, so high humidity can have adverse effects. When the air humidity is too high, water molecules in the air adhere to the skin, causing stickiness. If the respiratory tract is sensitive, breathing in high humidity air may also cause sneezing, runny nose, and coughing. When the air humidity is too low, the body loses moisture too quickly, which may lead to dehydration symptoms such as tight skin, sore throat, and thirst. Low humidity environments quickly evaporate the fluid from the respiratory mucosa, making it dry and fragile, reducing its ability to clear foreign objects, and increasing the risk of bacterial and viral invasion. Therefore, the user's comfortable humidity range can be calculated based on the difference between their age and a reference age. For example, if the reference age is 30 years old, and the user's age is a... 甲 For a person aged 50, the humidity regulation coefficient k 湿 If the humidity level is 2%, and the comfortable humidity range is 48%-68%, then the adjusted comfortable humidity range is 52%-60%.

[0103] In step S3, as Figure 4 As shown, adjusting the operating parameters of the operating mode based on the user's personal characteristics includes the following steps:

[0104] S331: Get the current season information;

[0105] S332: If the current season is spring or summer, then the comfortable temperature range is adjusted according to the user's gender, and the following relationship is satisfied:

[0106] T′=T+k 性 +s1;

[0107] Where T represents the upper or lower limit of the comfort temperature range, T′ represents the upper or lower limit of the adjusted comfort temperature range, and k 性 s1 represents the gender adjustment coefficient, and s1 represents the adjustment coefficient for spring or summer.

[0108] S333: If the current season is autumn or winter, the comfortable temperature range is adjusted according to the user's gender, and the following relationship is satisfied:

[0109] T′=T+k 性 -s2;

[0110] Where T represents the upper or lower limit of the comfort temperature range, T′ represents the upper or lower limit of the adjusted comfort temperature range, and k 性 s1 represents the sex adjustment coefficient, and s2 represents the adjustment coefficient for autumn or winter.

[0111] S334: Control the air conditioner to operate in temperature adjustment mode, and adjust the indoor temperature to the comfortable temperature range calculated in step S333.

[0112] Specifically, by considering seasonal and gender-specific characteristics, more precise comfort temperature regulation can be achieved. In spring and summer, users tend to wear short sleeves, while in autumn and winter, they tend to wear one long-sleeved shirt or multiple layers. Therefore, the comfort temperature range in autumn and winter is lower than that in spring and summer. Furthermore, there are significant differences in temperature perception between men and women; women are generally more sensitive to cold. By introducing a gender adjustment coefficient, the comfort temperature range can be personalized to meet the different physical needs of men and women, helping to improve user satisfaction and comfort. It also improves energy efficiency and reduces energy waste. This personalized adjustment method makes the air conditioner's operation more intelligent. For example, if the initial comfort temperature range is 20°C-25°C, the gender adjustment coefficient k... 性 The adjustment coefficient s1 is 0.5, meaning that the comfortable temperature range for women is 0.5℃ higher than that for men. If the adjustment coefficient s2 is 2 in spring, then the comfortable temperature range for women in spring is 22.5℃-27.5℃. If the adjustment coefficient s2 is 1 in winter, then the comfortable temperature range for women in winter is 19.5℃-24.5℃.

[0113] Furthermore, in step S3, adjusting the operating parameters of the operating mode based on the user's personal characteristic information includes the following steps:

[0114] Calculate the user's BMI data based on their height and weight;

[0115] If the user's BMI data is within the underweight range, then determine whether the user's heart rate is within the preset normal heart rate range. If so, adjust the air conditioner's fan speed to the second level. If the user's heart rate is higher than the normal heart rate range, adjust the air conditioner's fan speed to the third level. If the user's heart rate is lower than the normal heart rate range, adjust the air conditioner's fan speed to the first level.

[0116] If the user's BMI data is within the normal range, then determine whether the user's heart rate is within the preset normal heart rate range. If so, adjust the air conditioner's fan speed to the third level. If the user's heart rate is higher than the normal heart rate range, adjust the air conditioner's fan speed to the fourth level. If the user's heart rate is lower than the normal heart rate range, adjust the air conditioner's fan speed to the second level.

[0117] If the user's BMI is within the obese range, the system determines whether the user's heart rate is within the preset normal heart rate range. If so, the air conditioner's fan speed is adjusted to the fourth level. If the user's heart rate is higher than the normal heart rate range, the air conditioner's fan speed is adjusted to the fifth level. If the user's heart rate is lower than the normal heart rate range, the air conditioner's fan speed is adjusted to the third level.

[0118] Specifically, since everyone's physical condition and sensitivity to the environment differ, by considering physiological indicators such as the user's BMI (Body Mass Index) and heart rate, the air conditioner's fan speed can be adjusted more precisely, thus providing a personalized comfort experience. For example, a thinner user may feel cold more easily, so the air conditioner's fan speed will be lowered accordingly; while an obese user needs a stronger fan to achieve the same level of comfort. Heart rate is one of the important indicators reflecting a person's health status. By monitoring a user's heart rate and combining it with BMI data, a preliminary assessment of the user's physical condition can be made. For example, if a user's heart rate is abnormally high, it means that the user is engaged in strenuous exercise, has just finished strenuous exercise, or is in a state of tension. In this case, increasing the air conditioner's fan speed can help the user cool down quickly. If the heart rate is low, it means that the user is in a resting or relaxed state, and in this case, lowering the fan speed can prevent the user from feeling uncomfortable due to excessive airflow.

[0119] Furthermore, step S3 also includes identifying the user's level of perspiration;

[0120] If the user is slightly sweating or not sweating, adjust the angle between the air conditioner's airflow direction and the user to within the first angle range;

[0121] If the user is in a state of moderate sweating, adjust the angle between the air conditioner's air outlet direction and the user to within the second angle range;

[0122] If the user is sweating profusely, adjust the angle between the air conditioner's airflow direction and the user to within the third angle range;

[0123] Among them, the lower limit of the first included angle range is greater than the upper limit of the second included angle range, and the lower limit of the second included angle range is greater than the upper limit of the third included angle range.

[0124] Specifically, when the user is slightly sweating or not sweating, adjusting the angle between the airflow direction and the user to the first angle range (a larger angle) can reduce direct airflow and prevent the user from catching a cold. If the user is moderately sweating, adjusting the angle to the second angle range (a moderate angle) can help the user dissipate heat more quickly while maintaining a certain level of comfort and reducing discomfort. When the user is sweating heavily, adjusting the angle to the third angle range (a smaller angle) can more effectively deliver cool air to the user, helping the user cool down quickly and reducing discomfort caused by high temperature and excessive sweating. In this embodiment, the first angle range is 60°-90°, the second angle range is 30°-60°, and the third angle range is 0°-30°. This intelligent adjustment method not only improves the efficiency of the air conditioner, but also allows the air conditioner to automatically adjust according to the user's actual situation without the need for manual adjustment, providing a more considerate and personalized service.

[0125] Furthermore, in step S4, if the user actively adjusts the operating mode and operating parameters of the air conditioner within a preset second time interval after step S3, the historical operating mode and historical operating parameters under the current physiological state information, personal characteristic information and environmental information are recorded.

[0126] The next time a user uses the air conditioner, they will control it using the same historical operating mode and parameters based on the same physiological state information, personal characteristic information, or environmental information.

[0127] Specifically, after step S3, if the user actively adjusts the air conditioner's operating mode and parameters (such as adjusting temperature, fan speed, or airflow direction) within a preset time interval, the air conditioner interprets this behavior as an expression of dissatisfaction with the current settings or a specific need from the user. The air conditioner records the user's current physiological state information (such as heart rate), personal characteristics (such as age, gender, and preferences), and environmental information (such as indoor temperature, humidity, and light intensity). It also records the operating mode and parameters before the user's adjustment as historical operating modes and parameters, which are then used as the user's preference for the air conditioner's operating mode and parameters. When the user uses the air conditioner again, if one or more of the same physiological state information, personal characteristics, or environmental information match the previously recorded information, it will automatically recommend or directly apply the previously recorded historical operating modes and parameters to control the air conditioner. Through intelligent recommendation and automatic setting, the tediousness of manual adjustment by the user is reduced, improving convenience and satisfaction. The air conditioner can customize its operating mode and parameters according to the user's personal characteristics and preferences, providing a more personalized service.

[0128] Preferably, the environmental information also includes the space capacity of the room where the air conditioner is located;

[0129] Step S5 includes the following steps:

[0130] S51: Obtain the current user's perceived comfort level in the current environment from historical usage records;

[0131] Air conditioners extract user usage data from historical usage records to match current environmental information (such as temperature and humidity), with the aim of understanding users' comfort levels in similar environments through historical data.

[0132] S52: If the acquisition fails, combine the historical usage records of other users on the air conditioner under the current environmental information to determine the current user's perceived comfort level under the current environmental information.

[0133] If S51 acquisition fails, the air conditioner will analyze the historical usage records of other users under similar environmental conditions to identify users with similar characteristics to the current user, and infer the required level of comfort for the current user in the current environment based on the body sensation data of these similar users.

[0134] S53: Adjust the cooling capacity of the air conditioner according to the indoor space capacity and the user's physiological state information to make the user feel comfortable under the current environmental information.

[0135] The air conditioner takes into account the space (volume) of the room where it is located, as well as the user's physiological state, such as the degree of sweating and heart rate. For example, in a living room, the air conditioner's temperature detection device detects that the current temperature is 30°C, and the user's desired comfortable temperature is 24°C. Based on the room volume and the user's activity level, the air conditioner calculates that the required cooling capacity is 3000 watts. At this time, it detects that the user is sweating slightly, so the air conditioner sets the cooling capacity to 3300 watts and starts cooling at this power.

[0136] S54: After each preset first time interval, obtain the current environmental information. If the environmental information changes, execute steps S51-S53 to maintain the user's physical comfort.

[0137] The first preset time interval is used to periodically acquire environmental information, including temperature, humidity, or airflow. Once an environmental change is detected, the process returns to S51-S53, adjusting the cooling output to maintain the target temperature of 24°C and ensure user comfort.

[0138] Furthermore, in step S5, if there are two people in the room where the air conditioner is located:

[0139] Determine if the comfort levels of the two individuals are similar. If they are similar, adjust the cooling capacity of the air conditioner to meet the comfort level of one of them.

[0140] If they are not similar, adjust the cooling capacity of the air conditioner to adjust the user's perceived comfort to the middle value of the perceived comfort of the two.

[0141] If there are two or more people in the room where the air conditioner is located:

[0142] If multiple people have similar levels of comfort, the cooling capacity of the air conditioner is adjusted in the third time interval to meet the comfort level of the multiple people. In the fourth time interval, the cooling capacity of the air conditioner is adjusted to adjust the user's comfort level to the maximum or minimum value among the multiple people's comfort levels.

[0143] If multiple users do not have similar levels of comfort, the cooling capacity of the air conditioner should be adjusted to a value that is the median of the maximum and minimum levels of comfort among the multiple users.

[0144] Specifically, the air conditioner is equipped with sensors to identify the presence and identity of users, and obtain their perceived comfort levels from historical usage records. For example, if there are two users in the room where the air conditioner is located, and their perceived comfort levels are less than or equal to 1, then their perceived comfort levels are considered similar, and the air conditioner's cooling capacity can be adjusted to meet the needs of one of them. When their perceived comfort levels are not similar, for example, if user A's perceived comfort level is 25 and user B's perceived comfort level is 19, then the air conditioner needs to adjust its cooling capacity to make their perceived comfort level 22, balancing the needs of both users and preventing either user from feeling too uncomfortable. This midpoint adjustment helps reduce energy waste caused by over-adjustment by guiding the air conditioner to operate at a compromise point. Additionally, if there are multiple people in the room where the air conditioner is located, such as three users: A, B, and C, with their perceived comfort levels of 26, 26, and 21 respectively, since the perceived comfort levels of users A and B are similar, the air conditioner's cooling capacity will be adjusted first to bring their perceived comfort level to 26. The air conditioner will then be adjusted periodically to bring their perceived comfort level to 21, and after several more time intervals, it will be adjusted back to 26. If the perceived comfort levels of users A, B, and C are 26, 23, and 18 respectively, then the median value between the maximum and minimum values, 22, will be set as the target value for adjusting the air conditioner's cooling capacity to achieve the desired perceived comfort level. The air conditioner will be adjusted first to meet their shared needs, prioritizing the needs of the majority. Simultaneously, to ensure a comfortable experience for everyone, the air conditioner will adjust the comfort level of the remaining users at another time interval.
