Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a temperature control method for a wall-hanging stove according to an embodiment of the invention.
In this embodiment, the temperature control method for the wall-hanging stove includes the steps of:
s10: acquiring current body data of a user from a wearable device;
it is understood that a wearable device refers to a mobile smart device that can be worn directly on a person or can be incorporated into clothing, accessories and record body data.

The body data of the user are changed in real time, and the wearable device can continuously acquire the body data of the user within a period of time, so that the current body data can be understood as the body data of the user acquired by the wearable device at the current moment.
With the development of technology, intelligent wearable devices become important choices of consumers gradually, according to statistics of quarter tracking reports in IDC China wearable device market, the goods output of the intelligent wearable devices in China only in 2019 reaches 1 hundred million, according to investigation of relevant organizations, the annual growth rate of the intelligent wearable devices is about 30-50%, and the increment is considerable.
Compared with electronic equipment such as a mobile phone, the intelligent wearable equipment has the natural advantages of being wearable, and the wearable characteristics of the intelligent wearable equipment determine that the intelligent wearable equipment can collect key biological characteristic information (such as heart rate, blood oxygen, blood pressure, body temperature, motion state, body fatigue, sleep information, body pressure information, skin information, body identity information and the like) of a human body by carrying various sensor equipment. The smart watch in the wearable device can even carry satellite positioning systems such as GPS and Beidou, and Location Based Services (LBS) of the mobile phone is realized. The collected information is used as important decision content for subsequent processing, especially strong interaction with intelligent household appliances, more scenes such as identity authentication and health information can be achieved compared with a mobile phone, and interaction between a person and a machine can be promoted to be higher intensity by matching with the intelligent household appliances.

In a particular implementation, the server may obtain current body data of the user by communicating with the wearable device. In one embodiment, the wearable device can transmit current human body data to mobile terminals such as mobile phones, and the mobile terminals such as the mobile phones transmit the current human body data to the server through the gateway device, or the mobile terminals such as the mobile phones directly communicate through public cloud; in another embodiment, the wearable device may directly transmit the current human body data to the server through a public cloud, or may communicate with the gateway device through a Universal Subscriber Identity Module (USIM) Module, a bluetooth Module, a WiFi Module, or the like inside the wearable device, and transmit the current human body data through the gateway device.
S20: inputting the current human body data into a preset model to obtain a heating temperature;
it can be understood that the preset model can be obtained by performing data model building by using algorithms such as Xgboost, Catboost, LightGBM and the like and training based on the relationship between human body data and the heating temperature of the wall-hanging stove. In specific implementation, when the number of the wall-hanging furnaces is multiple and the wall-hanging furnaces are installed in different rooms, the preset model can be obtained based on training of the relationship among human body data, the on-off state of the wall-hanging furnaces, the positions of the wall-hanging furnaces and the corresponding heating temperatures. Accordingly, after the current human body data are input into the preset model, the on-off state of each indoor wall-mounted furnace and the heating temperature corresponding to each wall-mounted furnace can be obtained, and therefore each room can set comfortable temperature according to the human body data of a user. In another embodiment, the current human body data is input into a preset model, after the heating temperature corresponding to the current human body data is obtained, the current position information is obtained from the current human body data, and the heating temperature is sent to the wall-hanging stove corresponding to the current position information. Thus, the heating of a certain room can be independently adjusted according to the requirement.
The preset model is mainly based on a machine learning scheme, in other extensible schemes, a deep learning model based on a Long Short-Term Memory network (LSTM) model can be adopted, the LSTM model can well process a time sequence-based classification decision scheme, and a training processing framework of the whole model is the same as that of the machine learning model.
S30: and transmitting the heating temperature to the wall-hanging furnace so that the wall-hanging furnace can adjust the temperature according to the heating temperature.
It should be understood that the server may communicate the heating temperature to the wall-hanging stove by communicating with the wall-hanging stove. In an embodiment, the server issues the heating temperature to the inside automatically controlled board of hanging stove through gateway equipment in, and automatically controlled board control hanging stove intelligence adjusts the temperature to provide more comfortable house living environment, can the wall built-up heating automatically when the user leaves the home or when going on business, realized the purpose of fuel saving and environmental protection.
One of the usage scenarios of the present embodiment is: when the user leaves home, the wearable device detects the current human body data (including position information) of the user, and interacts with the server through the mobile phone or directly, the server processes the current human body data to obtain the heating temperature, and sends the heating temperature to the wall-mounted furnace through the gateway device, and the wall-mounted furnace cools down or closes according to the heating temperature to achieve the purpose of energy conservation.
Another usage scenario of this embodiment is: when a user is in a sleep state at home, the wearable device detects current human body data (including a skin drying state, a sleep state, electrocardiogram information and the like) of the user, the wearable device interacts with the server through a mobile phone or directly, the server processes the current human body data to obtain heating temperature, the heating temperature is issued to the wall-mounted furnace through the gateway device, and the wall-mounted furnace dynamically adjusts the temperature according to the heating temperature, so that the sleep quality cannot be influenced by dryness and humidity of the indoor environment and overhigh or overlow indoor temperature.
The embodiment acquires the current human body data of the user from the wearable device; inputting the current human body data into a preset model to obtain a heating temperature; and transmitting the heating temperature to the wall-hanging furnace so that the wall-hanging furnace can adjust the temperature according to the heating temperature. Wherein, through obtaining current human data from wearable equipment to confirm the heating temperature of hanging stove according to current human data, make the user when unable artifical heating temperature that sets up, the heating temperature of hanging stove still can change according to the human condition, and the heating temperature who has avoided the hanging stove is too high or low and influence user's use and experience.
Further, as shown in fig. 4, fig. 4 is a schematic diagram of a construction process of the predetermined model in fig. 2. In this embodiment, the preset model is obtained by the following steps:
s21: acquiring multiple groups of historical human body data of a user, wherein the human body data comprises multiple types of electrocardio information, position information and body temperature information;
it should be understood that the historical body data of the user may also be obtained from the wearable device, and after obtaining the historical body data, the data is taken as sample data. In an embodiment, the sample data may be divided into 5 parts, wherein 4 parts are used for training the model and 1 part is used for evaluating the model, and of course, other parts of the sample data may be divided, which is not limited in this embodiment.
S22: labeling temperature information corresponding to the wall-mounted furnace on each group of historical human body data to obtain labeled data;
each group of historical human body data needs to be labeled in advance, and if a certain group of historical human body data is: the temperature of the human body is 36 ℃, the heartbeat is 120 times/minute, and the position is a living room, and then the temperature corresponding to the historical human body data can be marked as 30 ℃.
S23: and training the initial model according to the marked data to obtain a preset model.
Specifically, the marked data can be encoded according to the temperature information and the preset temperature; extracting target characteristics from the coded data, wherein the target characteristics comprise a plurality of body temperature characteristics, heart rate characteristics, position characteristics, blood pressure characteristics and blood oxygen characteristics; and inputting the target characteristics into the initial model for training to obtain a preset model.
In a specific implementation, the preset temperature may be set to a common heating temperature of the wall-hanging stove, such as 27 ℃. By encoding the labeled data, the labeled data can be divided into a plurality of different modes, for example, mode 1 is off, mode 2 is cooling, mode 3 is heating, and mode 4 is holding temperature. For example, if the temperature marked by a certain group of historical human body data is 30 ℃, the group of historical human body data can be encoded into a mode 2, i.e., cooling, after the temperature is compared with a preset temperature.
In the process of extracting the target characteristics from the coded data, the coded data can be preprocessed, such as normalization processing, and the data are mapped into the range of 0-1, so that the iterative computation speed can be increased, and the convenience and the rapidness of data processing can be improved. After the coded data are normalized, PCA (principal component analysis) feature selection is carried out on the data, dimension reduction can be carried out on the data, and features (body temperature features, heart rate features, position features, blood pressure features, blood oxygen features and the like) which are relatively large in correlation with heating temperature are extracted, so that subsequent calculation is facilitated.
The initial model in this embodiment may be a variety of models, and taking the case that the initial model is an Xgboost model as an example, after the target feature is obtained, the target feature may be input into the Xgboost model for training; calculating the value of the loss function according to the output result of the Xgboost model; and adjusting the hyper-parameter of the Xgboost model according to the value of the loss function, and then continuing training to obtain a preset model.
Of course, before the target features are input into the Xgboost model, the target features may be scrambled, and by scrambling the data, the robustness of the data may be enhanced, and since the model ignores the order of the sample data during learning, a better learning effect may be generated.
It should be noted that extreme Gradient Boosting (Xgboost) is an open source machine learning project, which is developed from a Gradient Boosting Decision Tree (GBDT), and the GBDT algorithm is efficiently implemented and improved in algorithm and engineering based on the GBDT algorithm. Xgboost is an integrated machine learning algorithm based on a decision tree, and realizes the optimization process of learning by using an addition model and a forward step algorithm by taking gradient lifting as a framework. The method has the advantages of high speed, good effect, capability of processing large-scale data, supporting multiple languages, supporting custom loss functions and the like.
The base learner in the Xgboost may perform the boosting calculation based on a tree model, such as a Classification And Regression Tree (CART), or may perform the boosting calculation based on a linear model, such as a gbinear linear classifier.
After the initial model is constructed, the hyper-parameters of the initial model need to be set first, and the hyper-parameters need to be adjusted continuously in the training process of the model.
It should be understood that the hyper-parameters are parameters that are pre-defined before the learning process is started, and not parameters that are derived through training. In general, the hyper-parameters need to be optimized, and a set of optimal hyper-parameters is selected for the model, so as to improve the learning performance and effect. The commonly used method for adjusting parameters by using hyper-parameters comprises the following steps: grid search, random search, Bayesian optimization and the like.
In this embodiment, the hyper-parameters to be defined include a learning rate, a sampling depth, a sub-node weight, a down-sampling rate, and a joint sampling rate.
In one embodiment, the learning rate range is set to be 0.1-0.05, the sampling depth is any one natural number of 4, 5 and 6, the weight of the child node is 1 or 2, the down sampling rate is 0.9, and the joint sampling rate is 0.9.
During the training process, the value of the loss function can be calculated according to the output result of the Xgboost model; and adjusting the learning rate, the sampling depth and the sub-node weight of the Xgboost model according to the value of the loss function.
Wherein, when adjusting the learning rate, a difference between a previous value and a current value of the loss function may be calculated; determining a rate of decrease of the value of the loss function from the difference; when the falling speed becomes small, the learning rate is reduced.
The learning rate determines whether and when the objective function converges to a local minimum, and an appropriate learning rate enables the objective function to converge to a local minimum in an appropriate time. In an embodiment, when the initial value of the learning rate is 0.1, if the value of the loss function decreases and becomes slow as the number of iterations increases, the learning rate may be adjusted to be small, and if the trend of the change in the value of the loss function is stable, the learning rate may not be changed.
In an embodiment, when the sampling depth is 6, since the more the sampling depth is, the more the model tends to be locally optimized, and at the same time, the more the amount of calculation is, in order to prevent the model from being limited to the local optimization and make the model tend to be truly optimized, the sampling depth may be appropriately reduced according to the value of the loss function, such as setting the sampling depth to 4 or 5. As shown in fig. 5, fig. 5 is a training graph of an embodiment of iteration times (iterations) and loss function value (loss), and after the sampling depth is changed, the model can reach true optimum from local optimum.
In an embodiment, when the weight of the child node is 2, the left sub-tree node and the right sub-tree node with the focus weight greater than or equal to 2 are discarded step by step in the training process, so that the interference of the nodes with smaller weights can be reduced, and the accuracy of the model is improved.
In an embodiment, since the down-sampling rate and the joint sampling rate control the ratio of random sampling per tree, reducing the values of these two parameters makes the algorithm more conservative and avoids over-fitting, however, when the down-sampling rate and the joint sampling rate are set too small, the deviation of fitting of training samples may be increased, so that, after the down-sampling rate and the joint sampling rate are both set to 0.9 in model training, the down-sampling rate and the joint sampling rate are not adjusted or reduced properly in the training process.
In the training process of the model, the tree complexity formula is as follows:
wherein T is the number of leaf nodes of each tree,is the square of the weight of the leaf node on the tree, gamma is a penalty term of L1 regular, and lambda is a penalty term of L2 regular. In the training process, in order to prevent excessive data in the training process, lambda is usually set between 0 and 1.
It should be appreciated that in machine learning, an additional term is typically added to the loss function, commonly referred to as L1 regularization and L2 regularization. The regularization term is generally a monotonically increasing function of the complexity of the model, with the more complex the model, the larger the regularization value. Where L1 regularization is the sum of absolute values of each element in the vector, and L2 regularization is the squaring of each element of the vector, summing, and then square root.
Referring to fig. 6, fig. 6 is a training graph of another embodiment of the number of iterations of the preset model and the value of the loss function in fig. 2, as can be seen from fig. 6, as the number of iterations (iterations) increases, the logarithm (loglos) of the value of the loss function decreases rapidly, and when the number of iterations reaches 30, the logarithm of the value of the loss function approaches 0.1, which means that the model has strong generalization capability, occupies small resources, and is trained rapidly.
Further, when the historical human body data is divided into 5 parts, wherein 4 parts are used for training the model and 1 part is used for evaluating the model, after 30 iterations of the Xgboost model of the present embodiment, the preset model is evaluated by using the evaluation model, and it can be detected that the precision of the preset model reaches more than 99%.
In the embodiment, multiple groups of historical human body data of a user are acquired, wherein the human body data comprise multiple types of electrocardio information, position information and body temperature information; labeling temperature information corresponding to the wall-mounted furnace on each group of historical human body data to obtain labeled data; and training the initial model according to the marked data to obtain a preset model. The method has the advantages that the operation speed can be effectively increased by carrying out preprocessing such as labeling, coding and feature extraction on historical human body data, the Xgboost model is used as an initial model, the preset function is obtained by training, the training speed is high, the model precision is high, and the accuracy of heating temperature prediction is improved.
Further, as shown in fig. 7, fig. 7 is a schematic flow chart of another embodiment of the temperature control method of the present invention, and in this embodiment, the method further includes the following steps:
s40: determining whether the heating temperature is within a preset threshold range before transmitting the heating temperature to the wall-hanging stove;
it should be noted that, in order to ensure the accuracy of the wall-mounted boiler receiving the heating temperature, before the server sends the heating temperature to the wall-mounted boiler, the heating temperature needs to be verified to determine whether the temperature is within a reasonable range.
Typically, the minimum temperature of the wall-hanging stove is 10 ℃ or 20 ℃ and the maximum temperature is 30 ℃, so the prediction threshold range may be 10 ℃ to 30 ℃ or 20 ℃ to 30 ℃.
S50: and returning to the step of acquiring the current human body data of the user from the wearable device under the condition that the heating temperature is not within the preset threshold range.
