In this embodiment, in the step S306, the target operation parameter may include a target set temperature and a target outlet air temperature, and the parameter adjustment factor includes a set temperature adjustment factor and an outlet air temperature adjustment factor.
The step of determining the target set temperature of the air conditioner 10 includes: obtaining the initial set temperature of the air conditioner 10 according to the formula Ts＝Ts0+k1×TskCalculating a target set temperature of the air conditioner 10, wherein TsSetting the temperature, T, for the targets0To initially set the temperature, TskTo set the temperature adjustment factor, k1Is a preset constant. The initial set temperature may refer to a set temperature of the air conditioner 10 before the sign parameters of the target interactive user in the indoor environment of the indoor unit 110 of the air conditioner 10 are obtained. k is a radical of1The value may be any value within the range of 0.5 to 2, and may be 1, for example. The target set temperature refers to a temperature to which the indoor environment can be adjusted when the air conditioner 10 is operated. For example, the target set temperature may be set to 26 ℃. The air conditioner 10 is operated at the target set temperature to maintain or maintain the temperature of the indoor environment at 26 ℃.
The step of determining the target outlet air temperature of the air conditioner 10 may include: obtaining the initial outlet air temperature of the air conditioner 10 according to the formula Tps＝Tps0+k2×TpskCalculating the target outlet air temperature of the air conditioner 10, wherein TpsIs the target outlet air temperature, Tps0Is the initial outlet air temperature, TpskIs an air outlet temperature adjustment factor, k2Is a preset constant. The initial outlet air temperature may refer to the outlet air temperature of the air conditioner 10 before the sign parameters of the target interactive user in the indoor environment where the indoor unit 110 of the air conditioner 10 is located are obtained. k is a radical of2The value may be any value within the range of 0.5 to 2, and may be 1, for example. The outlet air temperature of the air conditioner 10 may refer to the coil temperature of the heat exchanger of the indoor unit 110.
That is, in step S306, the target set temperature of the air conditioner 10 is determined according to the set temperature adjustment factor, and the target outlet air temperature of the air conditioner 10 is determined according to the outlet air temperature adjustment factor.
For example, if the activity state of the target interactive user is detected to be a light motion state, the preset state factor correspondence relationship is queried, so that it can be determined that the set temperature adjustment factor is-2 and the outlet air temperature adjustment factor is-1, and if the initial set temperature of the air conditioner 10 is 27 ℃, the initial outlet air temperature is 25 ℃, at which time, the target set temperature is 27 ℃ +1 × (-2) ═ 25 ℃, and the target outlet air temperature is 25 ℃ +1 × (-1) ═ 24 ℃.
In some alternative embodiments, the target operation parameter of the air conditioner 10 may only include the target set temperature, and in this case, the step S306 is to determine the target set temperature of the air conditioner 10 according to the set temperature adjustment factor.
In other optional embodiments, the target operation parameter of the air conditioner 10 may only include the target outlet air temperature, and at this time, in step S306, the target outlet air temperature of the air conditioner 10 is determined according to the outlet air temperature adjustment factor.
In still other alternative embodiments, the wearable device may further have an infrared human detection sensor for detecting human body position information of the target interaction user. After the target set temperature and the target air outlet temperature of the air conditioner 10 are determined, the target air supply angle of the air conditioner 10 can be determined according to the human body position information of the target interaction user, so that the air conditioner 10 can supply air towards or avoid the target interaction user. For example, when it is determined that the target interactive user is in a light sleep state or a deep sleep state, the target air supply angle may be determined to avoid the air supply of the target interactive user, and when it is determined that the target interactive user is in a heavy exercise state, the target air supply angle may be determined to supply air toward the target interactive user according to the preset of the target interactive user.
The step S308 may include: the operation frequency of the compressor of the air conditioner 10 is determined according to the target operation parameter, and the compressor of the air conditioner 10 is controlled to operate according to the operation frequency.
In this embodiment, in the step of determining the operating frequency of the compressor of the air conditioner 10 according to the target operating parameter, the operating frequency of the compressor may be determined according to the target set temperature and the target outlet air temperature, so that when the air conditioner 10 operates according to the determined operating frequency of the compressor, the air conditioner 10 may adjust the air temperature of the indoor environment according to the target set temperature and the target outlet air temperature.
Since the principle of adjusting the operating frequency of the compressor is well known to those skilled in the art, it is not described herein.
After the step S308, the method further includes: the variation trend of the physical sign parameters of the target interactive user is obtained, and the target operation parameters of the air conditioner 10 are further adjusted according to the variation trend of the physical sign parameters. The change trend of the physical sign parameters refers to a trend that the value of each physical sign parameter changes along with time within a set time length. The set time period may be any time period within a range of 10 to 30min after the air conditioner 10 starts to operate according to the target operation parameter determined in step S306.
For example, the body temperature parameter, the heart rate parameter and the sweat parameter of the target interaction user may be detected simultaneously, a variation curve of the value of each physical sign parameter changing with time is obtained, and then the variation curve of each physical sign parameter is analyzed to determine the physical sign state of the target interaction user responding to the current operating state of the air conditioner 10, so as to further adjust the target operating parameter of the air conditioner 10 according to the physical sign state of the target interaction user. For example, if it is detected that the drop value of the body temperature parameter of the target interactive user within the set time period exceeds 0.8 ℃, the target set temperature and the target outlet air temperature of the air conditioner 10 may be increased, for example, may be increased by 1 ℃ respectively, regardless of the variation of the heart rate parameter and the sweat parameter.
After the air conditioner 10 is controlled to operate according to the target operation parameters, the target operation parameters of the air conditioner 10 are further adjusted according to the change trend of the sign parameters by detecting the change trend of the sign parameters of the target interaction user, so that the air conditioner 10 can timely adjust the target operation parameters according to the actual sign state of the target interaction user, the target interaction user is prevented from infecting air conditioning diseases, the automation degree of the air conditioner 10 is improved, and the air conditioner 10 is endowed with humanized characteristics.
By using the above method, the air conditioner 10 of this embodiment determines the parameter adjustment factor of the air conditioner 10 by comprehensively determining multiple sign parameters of the target interaction user, and determines the target operation parameter of the air conditioner 10 according to the parameter adjustment factor, so that the parameter adjustment factor can reflect the activity state of the target interaction user, and the adjusted target operation parameter can better conform to the current sign state of the user, which is beneficial to improving the adjustment accuracy of the air conditioner 10 and improving the user experience.
