[0032] Figure 2 FIG. 1 is a flow chart of a method for determining the blowing angle of an air conditioner provided by an embodiment of the present invention. Figure 2 As shown, the method includes the following steps S110-S140.

[0033] S110, obtaining the regional temperatures corresponding to each of the spatial regions.

[0034] In this embodiment, a temperature sensor, a heat flow sensor and a human body sensing sensor are respectively deployed in each spatial area, wherein: the temperature sensor is used to detect the regional temperature of the corresponding spatial area, the heat flow sensor is used to detect the air flow velocity of the corresponding spatial area, and the human body sensing sensor is used to detect the frequency of human activities in the corresponding spatial area.

[0035] After each sensor collects the corresponding environmental data, data transmission is realized through the Bluetooth module to transmit the corresponding environmental data to the corresponding air conditioner.

[0036] Furthermore, in some embodiments, after obtaining the regional temperature data and airflow velocity data uploaded by each sensor, the regional temperature data and airflow velocity data are fitted to make the temperature and heat flow distribution more natural and accurate, in line with the actual situation, and then the air conditioning blowing angle is adjusted based on the regional temperature data and airflow velocity data after fitting. Specifically, this embodiment can use a cubic spline interpolation algorithm for fitting.

[0037] S120: Determine a temperature difference region from the plurality of spatial regions according to the temperature of each region and a preset temperature difference threshold.

[0038] Specifically, see Figure 3 , step S120 specifically includes:

[0039] S1201. Determine the average temperature of the target space according to the temperatures of each area.

[0040] Specifically, the average temperature is determined by the following formula:

[0041]

[0042] Among them, T avg is the average temperature, n is the number of regional temperatures in the target space, T i is the regional temperature of the i-th spatial region.

[0043] S1202: Determine the temperature difference between the temperature of each area and the average temperature.

[0044] Specifically, the temperature difference of each spatial area is determined by the following formula:

[0045] ΔT i =T i -T avg ;

[0046] Where, ΔT i is the temperature difference of the ith spatial region, T i is the regional temperature of the ith spatial region, T avg is the average temperature.

[0047] S1203: Determine a spatial region in which the temperature difference is greater than the temperature difference threshold among the multiple spatial regions as the temperature difference region.

[0048] Specifically, when |ΔT i |>T threshold When , the area is determined as a temperature difference area, where T threshold is a preset temperature difference threshold.

[0049] In some embodiments, if there are no areas of temperature difference, that is, the temperature of each area in the target space is relatively uniform, the air conditioning blowing angle can be set to horizontal or slightly upward to promote air circulation, and the angle can be adjusted according to the air flow speed.

[0050] S130, obtaining the area weights corresponding to the temperature difference areas.

[0051] Specifically, each spatial region in the target space of this embodiment has a corresponding regional weight. The higher the regional weight, the more attention should be paid to the temperature regulation of the spatial region.

[0052] In some embodiments, the regional weights of different spatial regions may be obtained by manual setting; in other embodiments, the regional weights of each spatial region may also be determined automatically. Specifically, the regional weights of each temperature difference region are determined by the following steps (in this case, the regional weights of other spatial regions except the temperature difference region are also determined by this step):

[0053] Obtain the historical human activity frequencies corresponding to each of the temperature difference areas; and determine the regional weights of each of the temperature difference areas according to the corresponding historical human activity frequencies.

[0054] Specifically, the historical human activity frequency corresponding to each temperature difference area is obtained through the human body sensing sensor. For example, the historical human activity frequency of each temperature difference area within a historical month is obtained according to the historical records of each human body sensing sensor, and then the regional weight of each temperature difference area is determined according to the historical human activity frequency. Among them, the higher the historical human activity frequency, the higher the corresponding regional weight.

[0055] S140, determining a target blowing angle of the air conditioner according to each of the area weights and a direction vector of each of the temperature difference areas, wherein the direction vector is a direction vector from the air conditioner to the corresponding temperature difference area.

[0056] In this embodiment, after the target blowing angle is determined, the air conditioner discharges air based on the target blowing angle.

[0057] The above direction vector is a unit direction vector. In some embodiments, please refer to Figure 4 , step S140 includes:

[0058] S1401, determining an initial blowing angle according to each of the area weights and each of the direction vectors.

[0059] Specifically, the initial blowing angle is determined according to a preset initial blowing angle calculation formula, each of the area weights and each of the direction vectors, and the initial blowing angle calculation formula is:

[0060]

[0061] Wherein, θ1 is the initial blowing angle, diff_regions is the set of temperature difference regions, and w i is the regional weight corresponding to the ith temperature difference region, d i is the direction vector corresponding to the i-th temperature difference area, and γ is the adjustment coefficient.

[0062] S1402: Obtain an average airflow velocity in the target space.

[0063] Specifically, the average airflow velocity of the target space is determined by the following formula:

[0064]

[0065] Among them, V avg is the average airflow velocity, n is the number of spatial regions in the target space (or the number of heat flow sensors), V i is the airflow velocity in the ith spatial region (or the airflow velocity of the ith heat flux sensor).

[0066] S1403. Determine an air lifting speed according to the air outlet temperature of the air conditioner and the average temperature of the target space.

[0067] Among them, the air lifting speed includes the cold air descending speed or the hot air rising speed. When the air conditioner is in the cooling state, the air lifting speed is the cold air descending speed. When the air conditioner is in the heating state, the air lifting speed is the hot air rising speed.

[0068] Specifically, the cold air descent speed is calculated by the following formula:

[0069] V fall =α(T avg -T cold );

[0070] Among them, V fall is the cold air descending speed, T avg is the average temperature, T cold is the current cold air temperature blown out by the air conditioner, and α is the preset empirical coefficient.

[0071] Specifically, the rising speed of hot air is calculated by the following formula:

[0072] V rise =α(T hot -T avg );

[0073] Among them, V rise is the rising speed of hot air, T avg is the average temperature, T hot is the hot air temperature currently blown out by the air conditioner, and α is the preset empirical coefficient.

[0074] S1404: Based on a preset blowing angle adjustment model, the initial blowing angle is adjusted according to the average air flow velocity and the air lifting speed to obtain the target blowing angle.

[0075] Specifically, the air conditioner provided in this embodiment is deployed with a pre-trained blowing angle adjustment model, which is used to adjust the initial blowing angle based on the average air flow velocity and air lifting speed of the current space, so that the wind outlet trajectory of the wind blown out by the target blowing angle can accurately fall into the corresponding area.

[0076] In summary, the embodiment of the present invention is applied to an air conditioner, the air conditioner is used to adjust the temperature of a target space, the target space includes multiple spatial regions, and the method includes: obtaining the regional temperatures corresponding to each of the spatial regions; determining the temperature difference region from the multiple spatial regions according to the regional temperatures and a preset temperature difference threshold; obtaining the regional weights corresponding to each of the temperature difference regions; determining the target blowing angle of the air conditioner according to each of the regional weights and the direction vector of each of the temperature difference regions, the direction vector being the direction vector from the air conditioner to the corresponding temperature difference region. The embodiment of the present invention can automatically determine the blowing angle of the air conditioner according to the temperature of each region in the space, thereby realizing dynamic adjustment of the blowing angle of the air conditioner and improving the uniformity of the indoor temperature.

[0077] Figure 5 FIG. 1 is a flow chart of a method for determining an air blowing angle of an air conditioner provided by another embodiment of the present invention. Figure 5 As shown, the method for determining the blowing angle of the air conditioner in this embodiment includes steps S210-S270. Steps S210-S240 are similar to steps S110-S140 in the above embodiment and are not described in detail. Steps S250-S270 added in this embodiment are described in detail below.

[0078] S250. Based on a preset time interval, obtain the current average airflow velocity of the target space and the current temperature difference values ​​corresponding to each of the temperature difference areas.

[0079] The preset time interval may be 5 minutes, or may be adjusted to other values ​​according to actual needs, and the specific value is not limited in this embodiment.

[0080] In order to make the indoor temperature uniform more quickly, considering that there may be many factors in real scenes (such as furniture, walls, etc.) that affect the adjustment speed of regional temperature, the air conditioner in this embodiment will also dynamically compensate for the target blowing angle during operation.

[0081] First, it is necessary to obtain the current average airflow velocity of the target space and the current temperature difference values ​​corresponding to each of the temperature difference areas.

[0082] Specifically, first obtain the current regional temperature of each spatial area, then calculate the average temperature of the current regional temperature of each spatial area as the current average temperature, and then determine the absolute value of the difference between the current regional temperature of each spatial area and the current average temperature as the current temperature difference of each spatial area; at the same time, obtain the current airflow velocity of each spatial area, and then determine the current average airflow velocity based on the current airflow velocity of each spatial area.

[0083] S260: Determine a target adjustment angle according to the current average airflow velocity, each current temperature difference, each area weight, and each direction vector.

[0084] Specifically, in some embodiments, the target adjustment angle is determined by the following steps:

[0085] The target adjustment angle is determined based on a preset adjustment angle calculation formula, the current average airflow velocity, each current temperature difference, each area weight, and each direction vector. The adjustment angle calculation formula is:

[0086]

[0087] Wherein, Δθ is the currently calculated target adjustment angle, diff_regions is the set of temperature difference regions, ΔT i is the current temperature difference corresponding to the i-th temperature difference area, w i is the regional weight corresponding to the ith temperature difference region, d i is the direction vector corresponding to the ith temperature difference area, V avg is the current average airflow velocity, sgn is the sign function, and λ is the adjustment coefficient.

[0088] S270: Adjust the target blowing angle according to the target adjustment angle.

[0089] Specifically, the target blowing angle is adjusted by the following formula:

[0090] θ3=θ2+Δθ;

[0091] Among them, θ3 is the target blowing angle after the current adjustment, θ2 is the target blowing angle before the current adjustment, and Δθ is the currently calculated target adjustment angle.

[0092] In summary, during the operation of the air conditioner of this embodiment, the target blowing angle can be dynamically compensated, that is, the air outlet angle can be adjusted in real time during the operation of the air conditioner to improve the temperature adjustment effect.

[0110] Where, ΔT i is the temperature difference of the ith spatial region, T i is the regional temperature of the ith spatial region, T avg is the average temperature.

[0111] Specifically, when |ΔT i |>T threshold When , the area is determined as a temperature difference area, where T threshold is a preset temperature difference threshold.

[0113] Obtain the historical human activity frequencies corresponding to each of the temperature difference areas; and determine the regional weights of each of the temperature difference areas according to the corresponding historical human activity frequencies.

[0114] Specifically, the historical human activity frequency corresponding to each temperature difference area is obtained through the human body sensing sensor. For example, the historical human activity frequency of each temperature difference area within a historical month is obtained according to the historical records of each human body sensing sensor, and then the regional weight of each temperature difference area is determined according to the historical human activity frequency. Among them, the higher the historical human activity frequency, the higher the corresponding regional weight.
