in step S302, the heat-preservation bedding covering rate and the heat-preservation bedding heat-preservation coefficient of the target interactive user in the indoor environment of the indoor unit 110 of the air conditioner 10 are obtained.
The insulation bedding coverage may refer to the ratio between the exposed area of the target interactive user and the total body area of the target interactive user. The exposed area of the target interactive user refers to the area of the body part of the target interactive user that is not covered by the thermal bedding.
The thermal insulation bedding coefficient can be measured by the thermal conductivity of the thermal insulation bedding covered by the target interaction user, and the thermal insulation bedding coefficient can be determined according to the temperature change rate of the surface temperature of the thermal insulation bedding covered by the target interaction user.
In step S304, a target operation parameter of the air conditioner 10, such as a target operation temperature and/or a target operation humidity and/or a target air volume and/or a target air speed, is determined according to the insulation bedding coverage and the insulation bedding insulation coefficient.
And step S306, controlling the air conditioner 10 to operate according to the target operation parameters.
By using the above method, after the air conditioner 10 of the embodiment obtains the heat preservation bedding coverage rate and the heat preservation bedding heat preservation coefficient of the target interaction user in the indoor environment, the target operation parameters of the air conditioner 10 can be determined according to the heat preservation bedding coverage rate and the heat preservation bedding heat preservation coefficient, which improves the intelligent degree of the air conditioner 10, so that the air conditioner 10 can automatically determine the target operation parameters according to the sleep scene of the user, and improves the user experience.
In the step S302, the step of obtaining the insulation bedding covering rate and the insulation bedding insulation coefficient of the target interactive user in the indoor environment where the indoor unit 110 of the air conditioner 10 is located may include: and acquiring temperature field distribution data and/or image information of the target interactive user, and determining the heat preservation bedding covering rate and the heat preservation bedding heat preservation coefficient according to the temperature field distribution data and/or the image information.
In this embodiment, the cover rate of the thermal bedding and the thermal coefficient of the thermal bedding can be determined only according to the temperature field distribution data.
The temperature field distribution data of the target interactive user is used to record the distribution data of the temperature of the respective body part of the target interactive user over time and/or space. Although the target interaction user is covered with the heat preservation bedding when sleeping, the heat preservation bedding is thin, the temperature field detection device transmits a detection signal to the target interaction user to obtain a reflection signal of the detection signal, and the reflection signal of the detection signal is analyzed to obtain the temperature field distribution data of the target interaction user.
The heat preservation bedding covering rate and the heat preservation bedding heat preservation coefficient can be respectively determined by analyzing the temperature field distribution data of the target interaction user, the logic is simple, other structures do not need to be additionally arranged, the structure of the air conditioner 10 can be simplified, and the manufacturing cost is reduced.
The step of determining the insulating bedding cover ratio from the temperature field distribution data may comprise: and determining the exposed part area of the target interactive user according to the temperature field distribution data, and determining the heat preservation bedding covering rate according to the exposed part area. Wherein, the step of determining the cover rate of the thermal bedding according to the area of the exposed part may include: the method comprises the steps of obtaining the area of all body parts of a preset target interaction user, calculating the difference value between the area of all body parts of the preset target interaction user and the area of exposed parts, and then calculating the ratio of the difference value to the area of all body parts of the preset target interaction user to obtain the heat preservation bedding covering rate.
The step of determining the exposed area of the target interaction user from the temperature field distribution data may comprise: and clustering the temperature field distribution data of the target interaction user according to a preset clustering rule to obtain an exposed part outline of the target interaction user, and calculating the area of the exposed part outline to obtain the exposed part area of the target interaction user. When the area of the exposed part outline is calculated, the exposed part outline can be compared with a preset outline unit, and the area ratio between the exposed part outline and the outline unit is determined, so that the area of the exposed part outline is calculated by utilizing the area ratio and the area of the outline unit, and the area of the preset outline unit is a preset fixed value.
In the step of clustering the temperature field distribution data of the target interaction user according to the preset clustering rule, the temperature of each body part of the target interaction user at a certain moment can be analyzed, the temperature of the head of the target interaction user is taken as a reference temperature, the deviation degree (for example, variance) between the temperature of other body parts of the target interaction user and the reference temperature is calculated, and the body part with the deviation degree smaller than the preset deviation threshold value is marked to obtain the exposed part area of the target interaction user. The preset deviation threshold value can be any value within the range of 0.01-0.5.
The exposed part area of the target interaction user is determined through the temperature field distribution data of the target interaction user, and the exposed part area of the target interaction user can be accurately calculated, so that the adjusting precision of the air conditioner 10 can be improved, and the operation of the air conditioner 10 is more consistent with the current sleep state of the target interaction user.
The step of determining the insulation coefficient of the insulated bedding from the temperature field distribution data may comprise: and determining the temperature change rate of the heat preservation bedding of the target interactive user according to the temperature field distribution data, and determining the heat preservation coefficient of the heat preservation bedding according to the temperature change rate of the heat preservation bedding.
The rate of change in temperature of the thermal bedding means how fast the surface temperature of the thermal bedding changes with time. The step of determining a rate of temperature change of the insulated bedding of the target interactive user from the temperature field distribution data may comprise: and determining a temperature change curve of the heat preservation bedding of the target interaction user according to the temperature field distribution data, wherein the temperature change curve is a change curve of the temperature of the heat preservation bedding of the target interaction user along with the change of time, and determining the temperature change rate of the heat preservation bedding according to the temperature change curve.
In the step of determining the temperature change curve of the thermal insulation bedding of the target interactive user according to the temperature field distribution data, a part of the thermal insulation bedding can be selected for research, the temperature change curve is drawn by using the corresponding relation between the temperature of the part and the time, in the step of determining the temperature change rate of the thermal insulation bedding according to the temperature change curve, the slope of the temperature change curve within a certain set time can be used as the thermal insulation coefficient of the thermal insulation bedding, and the set time can be any value within the range of 5-15 min, for example, 10 min. When the temperature field distribution data of the target interaction user is subjected to clustering processing according to the preset clustering rule, the exposed part outline of the target interaction user can be obtained, and the non-exposed part outline of the target interaction user can also be obtained. The contour of the non-exposed part is the contour of the body part covered with the thermal bedding. Any position on the outline of the non-exposed part can be directly used as a research object, and any position in the outline of the non-exposed part can be selected as the research object to draw the temperature change curve.
The step of determining the insulation coefficient of the insulation bedding from the temperature change rate of the insulation bedding may include: the method comprises the steps of obtaining a plurality of preset temperature change rate ranges, wherein each temperature change rate range corresponds to one heat preservation bedding heat preservation coefficient, matching the temperature change rate of the heat preservation bedding with the preset temperature change rate ranges to determine the temperature change rate range to which the temperature change rate of the heat preservation bedding belongs, and taking the heat preservation bedding heat preservation coefficient corresponding to the temperature change rate range as the heat preservation bedding heat preservation coefficient.
The heat preservation coefficient of the heat preservation bedding can be any value within the range of 0.1-1, and the larger the heat preservation coefficient of the heat preservation bedding is, the better the heat preservation performance of the heat preservation bedding is. For example, the surface temperature of a chemical fiber quilt with the thickness of 2cm changes by 2 ℃ within 10 min; the surface temperature of the down quilt with the thickness of 5cm changes by 0.5 ℃, which shows that the thermal insulation performance of the down quilt with the large thickness is better than that of the chemical fiber quilt with the small thickness.
For example, the heat preservation coefficient of the heat preservation bedding can include 0.1, 0.5 and 1, and the corresponding temperature change rate ranges can be respectively more than 0.2 ℃/min, 0.05-0.2 ℃/min and less than 0.05 ℃/min. When the temperature change rate of the heat preservation bedding of the target interactive user is detected to be 0.05 ℃/min, the temperature change rate range of the temperature change rate of the heat preservation bedding is 0.05-0.2 ℃/min, and then the heat preservation coefficient of the heat preservation bedding can be determined to be 0.5.
In some alternative embodiments, the methods of obtaining the cover ratio and the heat retention coefficient of the heat retaining bedding may be transformed. The steps of obtaining the cover rate of the thermal bedding and the thermal coefficient of the thermal bedding of the target interactive user in the indoor environment of the indoor unit 110 of the air conditioner 10 may include: and acquiring image information of the target interactive user, and determining the heat preservation bedding covering rate and the heat preservation bedding heat preservation coefficient according to the image information.
The step of determining the cover ratio of the thermal bedding and the thermal coefficient of the thermal bedding from the image information may include: and obtaining a human body image sample and a heat preservation bedding image sample of a target interaction user which are stored in advance, and matching the image information with the human body image sample and the heat preservation bedding image sample to determine the heat preservation bedding covering rate and the heat preservation bedding heat preservation coefficient.
When the covering rate of the heat preservation bedding and the heat preservation coefficient of the heat preservation bedding need to be obtained, an inquiry request can be sent to the image acquisition device so as to obtain the image information of the target interaction user, and an AI intelligent recognition system in the image acquisition device can be driven to analyze and recognize the image information so as to obtain the covering rate of the heat preservation bedding and the heat preservation coefficient of the heat preservation bedding. The cloud platform of the air conditioner 10 may pre-store a human body image sample of a target interaction user who does not cover the thermal insulation bedding and a plurality of types of thermal insulation bedding image samples, and in the step of analyzing and recognizing image information by using the AI intelligent recognition system, may match the image information of the target interaction user with the pre-stored human body image sample of the target interaction user who does not cover the thermal insulation bedding, thereby determining a coverage rate of the thermal insulation bedding, and may also match the image information of the target interaction user with the pre-stored plurality of types of thermal insulation bedding image samples, thereby obtaining a type of the thermal insulation bedding, and determining a thermal insulation coefficient of the thermal insulation bedding according to the type of the thermal insulation bedding. The cloud platform of the air conditioner 10 also stores the type of each thermal bedding and the corresponding thermal coefficient of the thermal bedding.
In other alternative embodiments, the methods for obtaining the cover ratio and the heat retention coefficient of the heat-retaining bedding may be further transformed. The steps of obtaining the heat-preservation bedding covering rate and the heat-preservation bedding heat-preservation coefficient of the target interactive user in the indoor environment of the indoor unit 110 of the air conditioner 10 include: and acquiring the temperature field distribution data and the image information of the target interactive user, and determining the covering rate and the heat preservation coefficient of the heat preservation bedding according to the temperature field distribution data and the image information. That is, the temperature field distribution data and the image information can be comprehensively utilized to determine the cover rate and the heat-insulating coefficient of the heat-insulating bedding. For example, the exposed position of the target interactive user and the position of the covered thermal bedding may be determined according to the image information of the target interactive user, then the temperature field detection device is driven to detect the profile of the exposed position and the temperature variation curve of the thermal bedding, the covering rate of the thermal bedding is calculated according to the profile of the exposed position, and the thermal coefficient of the thermal bedding is calculated according to the temperature variation curve of the thermal bedding.
In step S304, the target operating parameter may at least include a target operating temperature. The target operation temperature refers to a temperature to which the indoor environment can be adjusted when the air conditioner 10 is operated. For example, the target operating temperature may be set to 26 ℃. Air conditioner 10 buttonOperating at the target operating temperature allows the temperature of the indoor environment to reach or be maintained at 26 ℃. Step S304 may include: according to the formula T ═ T0-aX-bY + c calculating a target operating temperature, wherein T is the target operating temperature and T is0The temperature value is a preset reference temperature value, X is the heat preservation coefficient of the heat preservation bedding, Y is the covering rate of the heat preservation bedding, and a, b and c are preset constants. T is0The temperature may be any value within the range of 20 to 30 ℃, for example, 24 ℃, 25 ℃ or 26 ℃. a. b and c may be any values in the range of 0.8 to 1.1, for example, a and b may be 0.9, and c may be 1.
When a and b are 0.9, c is 1, and T is0At 25 ℃, if the heat-insulating bedding heat-insulating coefficient is 0.1 and the heat-insulating bedding covering factor is 0, the target operating temperature calculated according to the formula is 25 to 0.9 × 0.1 to 0+1, which is 25.91 ℃, and at this time, the target operating temperature of the air conditioner 10 can be determined to be 26 ℃ according to the principle of rounding and taking integers.
When a and b are 0.9, c is 1, and T is0At 25 ℃, if the heat preservation coefficient of the heat preservation bedding is 1 and the cover rate of the heat preservation bedding is 1, the target operation temperature calculated according to the formula is 25-0.9 × 1-0.9+1 ═ 24.2 ℃, and at this time, according to the principle of rounding and taking an integer, the target operation temperature of the air conditioner 10 can be determined to be 24 ℃. The adjustment accuracy of the operating temperature of the air conditioner 10 may be set to 0.5 deg.c, and if the target operating temperature calculated according to the formula is 24.3 deg.c, the target operating temperature of the air conditioner 10 may be determined to be 24.5 deg.c, and if the target operating temperature calculated according to the formula is 24.1 deg.c, the target operating temperature of the air conditioner 10 may be determined to be 24 deg.c.
In some alternative embodiments, the target operation parameters of the air conditioner 10 may further include a target air speed and a target air volume, and if it is determined that the target operation temperature of the air conditioner 10 is lower than the initial operation temperature according to the insulation bedding coverage rate and the insulation bedding insulation coefficient, the target air speed and the target air volume of the air conditioner 10 may be appropriately increased. If it is determined that the target operating temperature of the air conditioner 10 is higher than the initial operating temperature according to the insulation bedding coverage and the insulation coefficient of the insulation bedding, the target air speed and the target air volume of the air conditioner 10 can be appropriately reduced.
In the step S306, if it is determined that the target operation parameter is the same as the initial operation parameter of the air conditioner 10 according to the step S304, the target operation parameter of the air conditioner 10 is not adjusted.
