Specifically, firstly, data collection is performed, training data and tests can be collected in a laboratory through an infrared device, for example, skin temperatures of different people including old people, children, men, women and the like in different seasons, such as forehead temperature, eye temperature, cheek temperature, nose temperature, hand temperature and the like, and it can be understood that different people can embody different human heat sensation, metabolic rate, clothing heat resistance, environmental conditions and the like in different seasons.

And secondly, performing model training, and screening, debugging and optimizing by using a training data model. Specifically, training data is input into the initial model, and then the initial model is debugged and optimized according to the model output result, so that the model output data can be closer to the real situation.

Again, a model is generated. Specifically, the trained optimal model output is selected.

Finally, the model is predicted, and the model predicts the test data to obtain the model accuracy, for example, in the embodiment of the disclosure, the accuracy of the adopted user individual body temperature and cold feeling decision tree model can reach more than 80%.

In an embodiment, the user's individual body temperature and coldness decision tree model reaching the expectation may be stored in advance in the storage unit of the controller 30 of the air conditioner 1. At least eight layers of temperature decision condition sets are configured in the user individual body temperature and cold feeling decision tree model of the embodiment of the disclosure, and the at least eight layers of temperature decision condition sets form a plurality of temperature decision branches. At least eight layers of temperature decision condition sets are configured in the user individual body temperature and cold feeling decision tree model, the at least eight layers of temperature decision condition sets form a plurality of temperature decision branches, and the first layer of temperature decision condition sets comprise: a decision condition based on the indoor ambient temperature, the second layer temperature decision condition set comprising: a third layer of temperature decision conditions based on the hand temperature and the average face temperature, the third layer of temperature decision conditions comprising: a fourth layer of temperature decision conditions based on the average face temperature and the hand temperature, the fourth layer of temperature decision conditions comprising: a fifth level of temperature decision conditions based on the average facial temperature and the hand temperature, the fifth level of temperature decision conditions comprising: and a decision condition based on the hand temperature and the indoor environment temperature, wherein the sixth layer of temperature decision condition comprises: a decision condition based on the hand temperature, the indoor ambient temperature, and the face average temperature, the seventh layer temperature decision condition comprising: a decision condition based on the hand temperature, the indoor ambient temperature, and the average face temperature, an eighth layer of temperature decision conditions comprising: a decision condition based on the hand temperature, the indoor ambient temperature, and the average face temperature. For example, fig. 4-7 are schematic diagrams of a portion of a user's personal temperature and coldness decision tree model according to an embodiment of the present disclosure, the model is similar to a tree, the left branch represents true, the right branch represents false, and a final result is output each time a series of determinations are made until no further branches. In some embodiments, the user individual temperature and coldness decision tree model may include at least eight layers of temperature decision condition sets and fifty-five temperature decision branches consisting of the at least eight layers of temperature decision condition sets, each temperature decision branch may have the same or different temperature decision conditions. Each branch of the model executes independent temperature and cold feeling judgment, each temperature judgment branch can output a corresponding temperature and cold feeling prediction result, and the temperature and cold feeling judgment final value, namely the output value of the user individual temperature and cold feeling decision tree model can be-1 (cold), 0 (neutral) and 1 (hot), so that the current temperature and cold feeling state of the user can be judged according to the output value of the user individual temperature and cold feeling decision tree model.

It is understood that the user's individual body temperature and coldness decision tree model shown in fig. 4-7 is merely an example of one model of an embodiment of the present disclosure, and that other suitable decision tree models may be used as desired based on the results of model training optimization and testing.

Specifically, in practical application, because the human body temperature detection device 10 is set to a position or a human body position of a user, the problem that the temperature of the set test point cannot be accurately collected often occurs, and therefore, in the embodiment of the present disclosure, the controller 30 obtains the average facial temperature of the facial temperature, so that the situation that a single test point cannot collect data can be avoided, which is more practical and more accurate in data collection.

Further, in the embodiment of the present disclosure, not only the face temperature of the individual user can represent the current feeling of warmth of the user, but also the indoor environment temperature can affect the user's experience of warmth, and the face and the hand are exposed but the temperatures of the face and the hand are deviated, so that the average temperature of the face, the temperature of the hand and the indoor environment temperature are comprehensively considered, the air conditioner 1 inputs the average temperature of the face, the temperature of the hand and the indoor environment temperature into the personal temperature and cold feeling decision tree model of the user, determining the temperature and cold feeling state of the target user according to the output value of the user individual temperature and cold feeling decision tree model, adjusting the current set target temperature according to the temperature and cold feeling state, controlling the air conditioner to operate according to the adjusted target temperature, therefore, the individual temperature and cold feeling comfort of the target user is met, the individual personalized and differentiated requirements of the user are improved, and the comfort of the air conditioner is improved.

Wherein, the user passes through the temperature that air conditioner APP that loads on the control terminal of air conditioner for example remote controller, drive-by-wire ware or the mobile intelligent device set for when current set target temperature can start, also can the user start the current temperature of air conditioner when individual comfort mode of user, does not do specific limit here.

In the disclosed embodiment, the facial temperature may include forehead temperature, eye temperature, nose temperature, and cheek temperature, although combinations of one or more of these may also be included. In consideration of the fact that the temperatures of different portions of the face also vary and the temperatures of some portions may not be collected at times, when the user individual comfort mode is operated, the controller 30 records the forehead temperature, the eye temperature, the nose temperature, and the cheek temperature of the target user for a preset time period, calculates the forehead temperature average, the eye temperature average, the nose temperature average, and the cheek temperature average for the preset time period, and performs a weighted calculation on the forehead temperature average, the eye temperature average, the nose temperature average, and the cheek temperature average to obtain the face average temperature. Wherein the weight of the forehead temperature average > the weight of the eye temperature average > the weight of the nose temperature average > the weight of the cheek temperature average.

For example, in an embodiment, the weighting formula for the face average temperature may be obtained by multiple linear regression of the collected data, for example, the formula is as follows:

T _{face part} ＝0.3347×T _{Forehead head} +0.3113×T _Eye(s) +0.1754×T _Nose +0.1696×T _Cheek +0.1881；

Wherein, T _{Face part} Is the average temperature of the face, T _{Forehead head} Is forehead temperature, T _Eye(s) Is the eye temperature, T _Nose Temperature of nose, T _Cheek Cheek temperature.

Of course, the above is one of the weighting formulas for obtaining the average temperature of the face according to the present disclosure, and other modification formulas based on this are also within the scope of the present disclosure.

The air conditioner 1 of the embodiment of the present disclosure adjusts the target temperature by using the user individual body temperature and coldness decision tree model established based on big data and artificial intelligence technology, and can make up the deficiency that the PMV prediction comfort model based on the general population weakens individual differences, so that the air conditioner 1 not only meets the comfort requirements of the general population, but also can realize the personalized comfort requirements of a single family user.

Specifically, when the air conditioner 1 operates in the user individual comfort mode, for example, when only one person is present in a room, the human body temperature detection device 10 collects the face temperature and the hand temperature of a target user in real time, the indoor temperature detection device 20 collects the indoor environment temperature in real time, and the controller 30 receives the temperature data and calls the user individual temperature and cold feeling decision tree model, compares the face average temperature, the hand temperature and the indoor environment temperature with each layer of temperature decision conditions in a plurality of temperature decision branches of the user individual temperature and cold feeling decision tree model to determine a target temperature decision branch, wherein each temperature decision branch in the model is executed independently, obtains an output value of the target temperature decision branch corresponding to the user individual temperature and cold feeling decision tree model, and takes the temperature feeling state corresponding to the output value as the temperature and cold feeling state of the target user, for example, the output value is-1, represents a user being colder; the output value is 0, which represents that the user is in a neutral state without cold or heat; the output value is 1, representing the user is hot. And then, the target temperature is adjusted according to the current temperature and cold feeling state of the user, and the frequency of a compressor, the rotating speed of a fan, the direction of an air guide strip and the like of the air conditioner are adjusted according to the adjusted target temperature, so that the comfort of the user can be improved, and the personalized comfort requirement of the user can be met.

The process of the controller recognizing the state of the user's coldness will be described with reference to the user's individual coldness decision tree model shown in fig. 4 to 7.

After the user activates the user individual comfort model, the controller 30 acquires T for the face average temperature _{Face part} T for indicating hand temperature _{Hand part} T for indication and indoor ambient temperature _Indoor Represents and converts T _{Face part} 、T _{Hand part} And T _Indoor Inputting a user individual temperature and cold feeling decision tree model such as the tree models shown in fig. 4-7, comparing the temperature value with the temperature decision condition in the model, executing each temperature decision branch independently until obtaining the output value of the model, and determining the current temperature and cold feeling state of the user based on the output value.

As shown in fig. 4 to 7, each temperature determination branch is illustrated, wherein the user personal temperature and coldness decision tree model of the embodiment of the disclosure recognizes a temperature decision condition with an indoor ambient temperature as a first layer, a temperature decision condition with the hand temperature and the face average temperature as a second layer, and a branch that continues to be different downward with a different temperature determination condition. In the embodiment, in the user individual temperature and coldness decision tree model, the average face temperature, the hand temperature and the indoor environment temperature have different temperatures under different decision conditions, for example, the threshold value of each decision condition of the average face temperature is a value between 33.20 ℃ and 37 ℃, the threshold value of each decision condition of the hand temperature is a value between 32.95 ℃ and 36.55 ℃, the threshold value of each decision condition of the indoor environment temperature is a value between 22.25 ℃ and 30.85 ℃, and the temperature change of the same part can be in a range of 0.1 ℃ to 0.5 ℃, so that the temperature and coldness state recognition is more precise.

Namely, if the current sensory temperature of the user is higher, the current set target temperature is reduced, so that the sensory temperature of the user is reduced, and the comfort is improved.

In the above description, the process of determining the state of the user's cold and warm feeling by using the user's individual body temperature and cold feeling decision tree model shown in fig. 4-7 is used, it can be understood that the process of identifying the user's cold and warm feeling of other models is also similar to the above process, but the hierarchy of the model, the temperature determination branches, and the temperature decision conditions of each node of each branch are different from the disclosed model.

Further, in some embodiments, in order to improve the accuracy of identifying the current temperature and coldness of the user based on the user individual temperature and coldness decision tree model, the controller 30 is further configured to periodically input the average facial temperature, the hand temperature, and the indoor environment temperature into the user individual temperature and coldness decision tree model to obtain a preset number of output values output by the user individual temperature and coldness decision tree model, count and classify the preset number of output values, and use a temperature and coldness state corresponding to an output value in a classification containing the largest number of output values as the temperature and coldness state of the target user. Therefore, the accuracy of personal temperature and coldness recognition of the user can be improved, the model can be further optimized by self-machine learning, the accuracy of the recognition result is further improved, and a virtuous circle is formed.

In some embodiments, the controller 30 is further configured to: the air conditioner 1 is in a heating mode, and if the temperature and cold feeling state of the target user is determined to be partial cold by continuous preset times, the rotating speed of an indoor fan of the air conditioner is increased; the air conditioner is in a heating mode, if the temperature and cold feeling state of the target user is determined to be a bias heat continuously for the preset times, the rotating speed of an indoor fan of the air conditioner is reduced; the air conditioner is in a refrigeration mode, if the temperature and cold feeling state of the target user is determined to be partial cold continuously for the preset times, the rotating speed of an indoor fan of the air conditioner is reduced; and the air conditioner is in a refrigeration mode, and if the temperature and cold feeling state of the target user is determined to be the bias heat continuously for the preset times, the rotating speed of an indoor fan of the air conditioner is increased. For example, the controller performs three judgments through the user individual temperature and coldness decision tree model to obtain independent temperature and coldness judgment values (-1, 0, 1), and then performs statistics to calculate the most corresponding temperature and coldness, which is the final output value of the temperature and coldness judgment.

For example, as shown in fig. 8, a flow chart of the overall operation logic of the comfort control of the air conditioner according to an embodiment of the present disclosure is shown. If the controller 30 outputs a heat bias (1) through the user individual body temperature and cold feeling decision tree model, the controller 30 sends a cooling signal, the temperature is reduced by 1 ℃ on the basis of the existing set temperature, if the controller 30 outputs a cold bias (1) through the user individual body temperature and cold feeling decision tree model, the controller 30 sends a heating signal, the temperature is increased by 1 ℃ on the basis of the existing set temperature, if the controller 30 outputs a neutral (0) through the user individual body temperature and cold feeling decision tree model, the controller 30 keeps the existing set constant, and the judgment period of each time is based on the air conditioner feedback time. If the temperature and cold feelings of the three continuous periods are predicted to be colder (or warmer), the individual temperature and cold feelings of the user are considered to be stronger, the first-gear air speed needs to be increased, otherwise, the air speed of the air conditioner is unchanged according to the original setting.
