The central position and the target position temperature of a plurality of persons are obtained through calculation by obtaining a second coordinate of the plurality of persons, the mixed air outlet direction of the frequency and the air outlet speed of the compressor is adjusted according to the target position temperature corresponding to the central position and the comparison relation between the target position temperature and the set temperature, so that cold air or hot air can be preferentially blown to the area where the central position is located when the air conditioner is used for refrigerating or heating, the temperature of the area where the user is located is changed, the space accuracy of temperature adjustment is improved, the indoor user can preferentially feel temperature change, the set temperature is rapidly approached, the user experience is improved, meanwhile, the cold air or hot air conveying of the air conditioner to the unmanned area is reduced, the utilization rate of the air conditioner to cold or heat is improved, and the energy consumption is reduced.
The air conditioner control method of the invention has the following beneficial effects:
in a preferred embodiment, the calculating the central positions of the plurality of persons and the target position temperatures corresponding to the central positions includes:
and taking a geometric mean of the second coordinates of the plurality of persons as a third coordinate of the central position.
And a third coordinate with the geometric mean value of the second coordinates of the plurality of persons as a central position is adopted, and the position is consistent with the set temperature as much as possible when the air conditioner is controlled to run. The position in the middle of many people can be made unanimous with the settlement temperature, can not make hot-blast or cold wind blow someone directly with great probability, has avoided this people to receive overheated or super-cooled air current, makes simultaneously that indoor a plurality of people are in under comparatively comfortable temperature, has improved user experience.
In a preferred embodiment, the calculating the center positions of the plurality of persons and the target position temperatures corresponding to the center positions includes:
and obtaining a first distance between the mobile temperature detection device and the indoor unit of the air conditioner according to a first coordinate of the mobile temperature detection device, obtaining a second distance between the central position and the indoor air conditioner according to a third coordinate of the central position, obtaining a first temperature gradient according to a difference value between the first temperature and the inlet air temperature and the first distance, correcting the first temperature gradient to obtain a second temperature gradient, and obtaining the target position temperature according to the inlet air temperature, the second temperature gradient and the second distance.
The first temperature gradient is obtained by obtaining the first distance between the mobile temperature detection device and the indoor unit of the air conditioner, the second temperature gradient is obtained by correction, the target position temperature of the central position can be obtained by matching the inlet air temperature and the second distance, the unknown temperature of an unspecified position is obtained, the operation of corresponding devices is controlled according to the comparison relation between the target position temperature of the central position and the set temperature, and therefore user experience is improved.
In a preferred embodiment, the correcting the first temperature gradient to obtain the second temperature gradient includes:
obtaining an air outlet direction, a current wind shield and a maximum wind shield;
obtaining a first included angle between a connecting line of the mobile temperature detection device and the air conditioner and the air outlet direction according to the first coordinate and the air outlet direction, obtaining a first correction coefficient according to the first included angle, wherein the first correction coefficient is in negative correlation with the first included angle, obtaining a second correction coefficient according to the ratio of the current wind gear to the maximum wind gear and the first correction coefficient, and obtaining a third temperature gradient according to the first temperature gradient and the second correction coefficient;
obtaining a second included angle between a connecting line of the central position and the air conditioner and the air outlet direction according to the third coordinate and the air outlet direction, and obtaining a third correction coefficient according to the second included angle, wherein the third correction coefficient is in negative correlation with the second included angle; and obtaining a fourth correction coefficient according to the ratio of the current windshield to the maximum windshield and the third correction coefficient, and obtaining the second temperature gradient according to the fourth correction coefficient and the third temperature gradient.
The connecting line of the mobile temperature detection device and the air conditioner is introduced into the first included angle of the air outlet direction, and the second correction coefficient is adjusted according to the size of the first included angle, so that the second correction coefficient is more accurate. The larger the first included angle is, the less the temperature of the corresponding indoor position is influenced by the cold/hot air discharged from the air conditioner. The smaller the first included angle is, the more the temperature of the corresponding indoor position is influenced by the cold air/hot air discharged by the air conditioner. When the first included angle is 0, that is, the first temperature gradient is actually a temperature gradient of the air outlet flow of the air conditioner, and the temperature gradient is actually larger than temperature gradients in other indoor directions, so that correction needs to be performed by a larger coefficient. When the outlet air level of the air-conditioning indoor unit is higher, the wind power of the air-conditioning indoor unit is relatively stronger, and the representativeness of the first temperature gradient is worse. Therefore, the second correction coefficient is related to the ratio of the current wind gear to the maximum wind gear, and the influence of the wind speed on the measurement result error can be reduced.
Similarly, a second included angle between a connecting line of the central position and the air conditioner and the air outlet direction is introduced into the third correction coefficient, so that the third correction coefficient is more accurate. The larger the second included angle is, the less the temperature of the corresponding indoor position is influenced by the cold/hot air discharged from the air conditioner. The smaller the second included angle is, the more the temperature of the corresponding indoor position is influenced by the cold air/hot air discharged by the air conditioner. When the second included angle is 0, that is, the second temperature gradient is actually the temperature gradient of the air outlet flow of the air conditioner. Thus, the resulting third temperature gradient requires a larger coefficient of enhancement, so that a more reliable second temperature gradient can be obtained. Moreover, the higher the outlet air level of the indoor unit of the air conditioner is, the stronger the wind power of the indoor unit of the air conditioner is, and the smaller the temperature loss in the outlet air direction is. And the third correction coefficient are related to the ratio of the current wind gear to the maximum wind gear, so that the accuracy of the second temperature gradient can be improved.
By adopting the correction method, the temperature gradient in the direction of a certain known temperature difference can be converted into the approximate temperature gradient in other directions, so that the method can adapt to the condition that the central position is at an unknown position in advance or the condition that the central position changes. The adaptability of the control method is improved.
In a preferred technical solution, the adjusting the compressor frequency, the air outlet speed and the air outlet direction according to the comparison relationship between the target position temperature and the set temperature includes:
in a cooling or heating mode, if the target position temperature does not reach the set temperature, at least one of increasing the compressor frequency, increasing the air outlet speed and enabling the air outlet direction to face the central position is executed;
and if the target position temperature exceeds the set temperature, performing at least one of reducing the frequency of the compressor, reducing the air outlet speed and deviating the air outlet direction from the central position.
When the set temperature is not reached, at least one of increasing the frequency of the compressor, increasing the air outlet speed and enabling the air outlet direction to face the central position is executed, so that the speed of reaching the set temperature in the central position area is increased, in addition, the air outlet direction faces the central position, the utilization rate of the refrigerating or heating power of the air conditioner can be improved, and cold air/hot air is prevented from being blown to the area with little sense of improving users. And when the temperature exceeds the set temperature, at least one of reducing the frequency of the compressor, reducing the air outlet speed and enabling the air outlet direction to deviate from the central position is executed, so that the temperature of the target position of the central position area can be recovered to the set temperature more quickly, and the area where the user is located is more comfortable. And, with air-out direction principle central point, can deviate the user with the cold wind/hot-blast that blows out of air conditioner to avoid the user to receive unexpected cold wind or hot-blast blow directly, reduce user's negative experience.
In a preferred technical scheme, according to the comparative relation between the target position temperature and the set temperature, adjusting the frequency, the air outlet speed and the air outlet direction of the air conditioner compressor comprises:
if the air conditioner is in a cooling mode,
if the temperature of the target position is in a first temperature interval, controlling the frequency of the compressor to decrease at a first frequency reduction speed, reducing the wind speed grade of an indoor fan, and adjusting the air outlet direction to be far away from a target area;
if the target position temperature is in a second temperature interval, controlling the frequency of the compressor to decrease at a second frequency reduction speed, and maintaining the wind speed grade of the indoor fan;
if the target position temperature is in a third temperature interval, controlling the frequency of the compressor to be unchanged, and maintaining the wind speed grade of the indoor fan;
if the target position temperature is in a fourth temperature interval, controlling the frequency of the compressor to decrease at a first frequency increasing speed, and maintaining the wind speed grade of the indoor fan;
if the target position temperature is in a fifth temperature interval, controlling the frequency of the compressor to decrease at a second frequency increasing speed, increasing the wind speed grade of the indoor fan, and adjusting the wind outlet direction to be close to a target area;
the fifth temperature interval is higher than the fourth temperature interval, the third temperature interval is higher than the second temperature interval, and the set temperature is located in the third temperature interval.
Under the refrigeration mode, when the target location temperature is higher than the settlement temperature when more, through making the air-out direction be close to the target area to promote the windscreen, make cold wind can more concentrate blow in central point department of putting, reduce near central point's temperature, the user that is in this region can feel the temperature sooner and be close to the settlement temperature, has improved the centrality of cold volume utilization, has improved the availability factor of air conditioner, improves user experience. When the temperature of the target position is not much higher than the set temperature, cold air does not need to be blown to the target area in a concentrated and high-speed manner, so that the user is prevented from being under concentrated blowing of the cold air for a long time, and the risk of catching a cold is reduced. And when the temperature of the target position is too cold, cold air can be moved out of the target area, the frequency and the air speed of the compressor are reduced, the position of the target area is restored to the set temperature as soon as possible, and therefore the comfort of a user is improved.

the fifth temperature interval is higher than the fourth temperature interval, the third temperature interval is higher than the second temperature interval, and the set temperature is located in the third temperature interval.
Under the mode of heating, when the target location temperature is less than the settlement temperature when more, through making the air-out direction be close to the target area to promote the wind-break, make hot-blast can more concentrate and blow in central point department of putting, improve near the temperature of central point, the user that is in this region can feel the temperature more fast and be close to the settlement temperature, has improved the centralization of heat utilization, has improved the availability factor of air conditioner, improves user experience. When the temperature of the target position is not much lower than the set temperature, hot air does not need to be blown to the target area intensively and at high speed, so that the user is prevented from being under the intensive blowing of the hot air for a long time, and the feeling that the user is broiled by the hot air is reduced. When the temperature of the target position is overheated, the hot air can be moved out of the target area, the frequency and the wind speed of the compressor are reduced, the position of the target area is restored to the set temperature as soon as possible, and therefore the comfort of a user is improved.
In an optimal technical scheme, if the mobile temperature detection device cannot be detected or the people in the room cannot be detected, the frequency of the compressor and the air outlet speed are controlled according to the air inlet temperature.

S221, calculating the central positions of the multiple persons: a third coordinate (x) having a geometric mean of the second coordinates of the plurality of persons as a center position 0 ，y 0 )。
Specifically, the center position x of a plurality of persons is calculated 0 And y 0 Including, x 0 ＝(x 1 +x 2 +……+x n )/n，y 0 ＝(y 1 +y 2 +……+y n )/n
A third coordinate (x) having a geometric mean of the second coordinates of the plurality of persons as a center position 0 ，y 0 ) When the operation of the air conditioner is controlled, the position is made to coincide with the set temperature as much as possible. The temperature control device has the advantages that the middle position of a plurality of people is consistent with the set temperature, hot air or cold air cannot be directly blown to a certain person with high probability, the people are prevented from being subjected to overheated or supercooled air flow, meanwhile, a plurality of indoor people are in a comfortable temperature, and user experience is improved.
S222, calculating the target position temperature T corresponding to the central position 0 The method comprises the following steps:
detecting a first coordinate (x) of the device based on the mobile temperature T ，y T ) Obtaining a first distance S between the mobile temperature detection device and the indoor unit of the air conditioner T Third coordinate (x) according to the center position 0 ，y 0 ) Obtaining a second distance S between the central position and the indoor air conditioner 0 And in dependence on the first temperature T 1 Temperature T of inlet air 2 And a first distance S T Obtaining a first temperature gradient DeltaT 1 Correcting the first temperature gradient DeltaT 1 Obtaining a second temperature gradient DeltaT 2 According to the temperature T of the inlet air 2 Second temperature gradient DeltaT 2 And a second distance S 0 Obtaining a target position temperature T 0 。
Specifically, the first distance S between the mobile temperature detection device and the indoor unit of the air conditioner T May be determined by the first coordinate (x) of the mobile temperature sensing device T ，y T ) According to the Pythagorean theorem, i.e. S T ＝(x T 2 +y T 2 ) 1/2 . In the application, only the two-dimensional size in a plane is considered, and the influence caused by the height difference of the central position, the mobile temperature detection equipment and the indoor unit of the air conditioner is not calculated. Second distance S between the central position and the indoor air conditioner 0 Or from a third coordinate (x) of the central position 0 ，y 0 ) Result in, i.e. S 0 ＝(x 0 2 +y 0 2 ) 1/2 . First temperature gradient DeltaT 1 For the temperature variation per unit distance from the mobile temperature detection device to the air inlet of the air conditioner, specifically, delta T 1 ＝(T 2 -T 1 )/S T . And a second temperature gradient DeltaT 2 Is the temperature variation per unit distance from the air inlet to the center of the air conditioner, specifically, delta T 2 ＝(T 2 -T 0 )/S 0 Accordingly, T 0 ＝T 2 -△T 2 *S 0 。

More specifically, the first temperature gradient DeltaT is corrected 1 Obtaining a second temperature gradient DeltaT 2 The method comprises the following steps:
obtaining an air outlet direction, a current wind shield N and a maximum wind shield N;
according to a first coordinate (x) T ，y T ) And the air outlet direction obtains a first included angle theta between the connecting line of the mobile temperature detection equipment and the air conditioner and the air outlet direction T ，θ T ＝|θ-arctan(y T /x T ) And | and theta are an included angle between the air outlet direction and the x axis.
According to the first included angle theta T Obtaining a first correction coefficient k 1 First correction coefficient k 1 At a first angle theta T And (4) carrying out negative correlation. Specifically, when theta T When the angle is less than or equal to 15 degrees, k 1 =0.15; when 15 DEG < theta T When the angle is less than or equal to 30 degrees, k 1 =0.1; when 30 DEG < theta T When the angle is less than or equal to 45 degrees, k 1 ＝0.05；θ T When greater than 45 deg., k 1 ＝0。
According to the ratio of the current wind gear N and the maximum wind gear N and a first correction coefficient k 1 Obtaining a second correction coefficient k T1 . Specifically, k T1 ＝k 1 *n/N。
According to a first temperature gradient DeltaT 1 And a second correction coefficient k T1 Obtaining a third temperature gradient DeltaT 3 (ii) a In particular, Δ T 3 ＝△T 1 /(1+k T1 )。
According to the third coordinate (x) 0 ，y 0 ) And the air outlet direction obtains a second included angle theta between the connecting line of the central position and the air conditioner and the air outlet direction 0 ，θ 0 ＝|θ-arctan(y 0 /x 0 )|；
According to a second included angle theta 0 Obtaining a third correction coefficient k 2 Third correction factor k 2 At a second angle theta 0 A negative correlation. Specifically, when theta 0 When the angle is less than or equal to 15 degrees, k 2 =0.15; when 15 DEG < theta 0 When the angle is less than or equal to 30 degrees, k 2 =0.1; when 30 DEG < theta 0 When the angle is less than or equal to 45 degrees, k 2 ＝0.05；θ 0 When the angle is more than 45 DEG, k 2 ＝0。
According to the ratio of the current wind shield N to the maximum wind shield N and a third correction coefficient k 2 Obtaining a fourth correction coefficient k T2 In particular, k T2 ＝k 2 *n/N。
According to a fourth correction coefficient k T2 And a third temperature gradient DeltaT 3 Obtaining a second temperature gradient DeltaT 2 . Specifically, Δ T2=Δt 3 *(1+k T2 )
A first included angle theta between a connecting line of the mobile temperature detection equipment and the air conditioner and the air outlet direction T Is introduced and according to a first angle theta T Is adjusted by the second correction coefficient k T1 The second correction coefficient k can be made to be T1 And is more accurate. First included angle theta T The larger the temperature, the less the temperature at the corresponding position in the room is affected by the cool/hot wind discharged from the air conditioner. First included angle theta T The smaller the temperature, the more the temperature of the corresponding indoor location is affected by the cool/hot wind discharged from the air conditioner. When the first included angle theta T At 0, i.e., the first temperature gradient DeltaT is illustrated 1 In fact, the temperature gradient of the air conditioner outlet air flow is actually greater than the temperature gradient in other indoor directions, and therefore, the correction needs to be performed by a larger coefficient. When the outlet air gear of the air-conditioning indoor unit is higher, the higher the wind power of the air-conditioning indoor unit is, the stronger the wind power of the air-conditioning indoor unit is, and the first temperature gradient delta T is 1 The worse the representativeness of (a). Therefore, the second correction coefficient k is made T1 The influence of the wind speed on the error of the measurement result can be reduced in relation to the ratio of the current wind shield N to the maximum wind shield N.
Similarly, a second included angle theta between a connecting line of the central position and the air conditioner and the air outlet direction 0 Introduced into the third correction coefficient k 2 In (3), the third correction coefficient k may be made 2 And is more accurate. Second clipAngle theta 0 The larger the temperature, the less the temperature at the corresponding position in the room is affected by the cool/hot wind discharged from the air conditioner. Second included angle theta 0 The smaller the temperature, the more the temperature of the corresponding indoor location is affected by the cool/hot wind discharged from the air conditioner. When the second included angle theta 0 When 0, i.e., the second temperature gradient DeltaT 2 In effect, is the temperature gradient of the air conditioner outlet air flow. Thus, a third temperature gradient DeltaT is obtained 3 A larger coefficient of enhancement is required so that a more reliable second temperature gradient Δ T can be obtained 2 . Moreover, the higher the outlet air level of the indoor unit of the air conditioner is, the stronger the wind power of the indoor unit of the air conditioner is, and the smaller the temperature loss in the outlet air direction is. So that the third correction coefficient k 2 And a third correction coefficient k 2 Depending on the ratio of the current wind position N to the maximum wind position N, the second temperature gradient Δ T may be increased 2 The accuracy of (2).
