[0012] Analysis module: Processes historical data and performs predictive analysis using machine algorithms. The specific steps for predicting air conditioner turn-on time are as follows:

[0013] First, using sensors to collect ambient temperature T(t), ambient humidity H(t), light intensity L(t), user behavior data U(t), and timestamp t, these data are expressed as:

[0014] X(t)=[T(t);H(t);L(t);U(t)]

[0015] This is the multidimensional time series expression for these data;

[0016] Second, each feature in the data is dimensionless, so that all features are in a standard set. The formula for calculating the feature standard is:

[0017]

[0018] Where u is the mean of the feature and σ is the standard deviation of the feature;

[0037]

[0038] The loss function is minimized and the model parameters are updated using the backpropagation algorithm and optimizer.

[0053] The smart switch for home appliances provided in this specific embodiment, such as Figure 1As shown, it includes:

[0054] 1. Smart Meter Module: Employing high-precision current and voltage sensors, it accurately measures current, voltage, and power. Simultaneously, it incorporates a high-performance metering chip capable of rapidly processing sensor data to calculate real-time power and cumulative electricity consumption. The smart meter can monitor a household's total electricity consumption in real time, updating at a frequency of once per second or higher. This ensures the system can accurately monitor and analyze electricity usage. The smart meter not only records electricity consumption but also retrieves current electricity price information. Electricity price information is typically obtained from the power company's server via the internet, ensuring data timeliness and accuracy. The smart meter has built-in memory to store historical electricity consumption data and price information. Data is transmitted to the central control unit via wireless or wired communication, ensuring data integrity and security.

[0055] 2. Smart Socket and Switch Module: Employing high-precision current and voltage sensors, these modules accurately measure the power consumption of appliances. They also integrate a high-performance control chip for rapid data processing and execution of user control commands. Smart sockets and switches support remote control, allowing users to control the on / off status of appliances anytime, anywhere via smartphones, tablets, and other devices. This remote control function is achieved through wireless communication, ensuring timely and reliable control. Smart sockets and switches also feature a built-in timer function, allowing users to set the on / off times of appliances for timed control. This timer function can optimize appliance operating time based on user habits and electricity pricing information, reducing electricity costs. Smart sockets and switches are typically installed at the appliance's power outlet or switch location to ensure real-time monitoring and control of the appliance's operating status. During installation, it is crucial to ensure a secure connection between the device and the power system to prevent electrical faults.

[0056] Third, the central control unit module: Employing a high-performance embedded processor or industrial computer, it receives data from smart meters, smart sockets, switches, and sensor modules, processes and analyzes the data to calculate optimal appliance operating times and power settings based on electricity price information, device status, and user preferences. The central control unit is typically installed in the home's distribution box or central location, ensuring stable and reliable communication with all modules. During installation, good heat dissipation is crucial to prevent overheating from affecting system performance.

[0057] Fourth, the user interface module: This can be a smartphone application, tablet application, or a web-based control panel, supporting multiple operating systems and device platforms to display real-time appliance on / off status, power consumption, and electricity price information. It also provides settings and control functions, allowing users to customize appliance operating times and priorities according to their needs and preferences. The user interface application needs to be easy to install and configure; users can download and install smartphone applications from app stores or access the web control panel through a browser.

[0058] 5. Communication Modules: These include, but are not limited to, Wi-Fi, Zigbee, Bluetooth, and Ethernet, responsible for data transmission between modules. The stability and reliability of data transmission are fundamental to the normal operation of the system. Communication modules need to have anti-interference capabilities and high bandwidth to ensure data transmission quality. Communication modules support multiple communication protocols, such as TCP / IP, MQTT, and CoAP. Different communication protocols have different characteristics and application scenarios. The installation and configuration of communication modules need to be simple and easy to perform, ensuring that devices can quickly and stably connect to the system. Wireless communication modules typically support automatic network configuration and rapid setup, while wired communication modules need to consider cabling and interface compatibility.

[0059] Sixth, the sensor module: Used to monitor environmental parameters in the home to optimize appliance operation; it also monitors user behavior parameters to analyze usage habits and preferences. The sensor module can monitor various parameters in the home environment in real time, such as temperature, humidity, light, and air quality. This data can be used to optimize appliance operation and improve the comfort and convenience of home life. The sensor module can also monitor user behavior, such as movement, sleep, and activity. This data can be used to analyze user habits and preferences to provide personalized services and experiences. The installation location of the sensor module needs to be selected according to monitoring needs to ensure accurate data collection. Temperature sensors are typically installed in the center of the room, humidity sensors in well-ventilated areas, light sensors in areas with significant light changes, and motion sensors in areas of frequent user activity.

[0060] 7. Analysis Module: This module processes historical data and performs predictive analysis using machine algorithms. By analyzing user behavior data, it understands user habits and preferences, enabling the provision of personalized services and experiences. User behavior analysis includes activity patterns, usage frequency, and time preferences, which can be used to optimize the operating status and time settings of appliances.

[0061] For example, the specific steps for predicting when the air conditioner will turn on are as follows:

[0062] Step 1: Collect ambient temperature T(t), ambient humidity H(t), light intensity L(t), user behavior data U(t), and timestamp t using sensors, and express these data as follows:

[0063] X(t)=[T(t);H(t);L(t);U(t)]

[0064] This is the multidimensional time series expression for these data;

[0065] Step two: Dimensionless processing is performed on each feature in the data, so that all features reside in a standard set. The formula for calculating the feature standard is:

[0066]

[0067] Where u is the mean of the feature and σ is the standard deviation of the feature;

[0068] Step 3: Construct the time series data into an LSTM input format. Suppose we use data from the past k time steps to predict the future air conditioning start-up time Y(t):

[0069]

[0070] Among them, X norm (t) is the standardized feature, and the target slip wire predicts the future air conditioning start time Y(t);

[0071] Step four, the internal calculation formula of the LSTM unit is as follows:

[0072] First, regarding the Forgotten Gate:

[0073] f t =σ(W f [h t-1 ,x t ]+b f )

[0074] Secondly, regarding the input gate:

[0075] i t =σ(W i [h t-1 ,x t ]+b i )

[0076]

[0077] Secondly, regarding cell state updates:

[0078]

[0079] Finally, regarding the output gate:

[0080] o t =σ(W o [h t-1 ,x t ]+b o )

[0081] h t =o t ⊙tanh(C t )

[0082] Where σ is the sigmoid function, tanh is the tanh function, ⊙ represents element-wise multiplication, and W and b are the weight matrix and bias vector, respectively.

[0083] Step 5: The LSTM output passes through a fully connected layer to obtain the predicted value.

[0084]

[0085] The loss function is the mean squared error:

[0086]

[0087] The loss function is minimized and the model parameters are updated using the backpropagation algorithm and optimizer.

[0088] Step 6: Use the model to make predictions:

[0089]

[0090] This is the formula for predicting when the air conditioner will start.
