[0002] With the rapid development of the Internet of Things and smart home technologies, more and more smart devices are being used in home environments. These devices, such as smart lights, speakers, air conditioners, cameras, etc., are usually connected through wireless networks such as Wi-Fi, Zigbee, Bluetooth or 5G. However, there are many technical problems in the current smart home system, including uneven signal coverage, signal attenuation caused by physical obstacles (such as walls, furniture, etc.), wireless signal interference between devices, network congestion, etc. These problems lead to delays in device control, disconnection, and even functional failure. Traditional smart central control screens can only manage smart devices through a simple interface, and cannot optimize the quality of wireless communication when signal problems occur. Based on the above, this application proposes a multifunctional intelligent central control system based on reconfigurable smart surface technology. Summary of the invention

[0007] Its smart central control screen integrates a large-size high-definition touch screen as the interactive interface between the user and the smart home system. The large-size high-definition touch screen is used to display the real-time status of all smart devices in the home, including signal strength, device switches and working modes.

[0008] Preferably, the reconfigurable smart surface RIS module is composed of a plurality of programmable phased array units, which can change the reflection phase and direction of the signal by voltage adjustment. The reconfigurable smart surface RIS module is installed in the housing of the smart central control screen, the wall of the home, and the ceiling as the core component for signal transmission optimization;

[0009] The reconfigurable intelligent surface RIS module controls the propagation path of wireless signals and actively adjusts the reflection angle of signals by changing the phase distribution of the phased array units on the surface.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-2 , a multifunctional intelligent central control system based on reconfigurable intelligent surface technology, including an intelligent central control screen display and interaction module, a multi-device management and control module, an energy consumption management module, a signal optimization and dynamic adjustment module and a reconfigurable intelligent surface RIS module, the multi-device management and control module is connected with the intelligent central control screen display and interaction module, the energy consumption management module, the signal optimization and dynamic adjustment module and the reconfigurable intelligent surface RIS module, the signal optimization and dynamic adjustment module is connected with the reconfigurable intelligent surface RIS module and the intelligent central control screen display and interaction module, and the reconfigurable intelligent surface RIS module is connected with the energy consumption management module;

[0021] The smart central control screen display and interaction module includes a smart central control screen, which has a built-in wireless communication module. The smart central control screen is connected to home appliances via a wireless network and displays a real-time diagram of network signal coverage. The screen interface of the smart central control screen is used to display a list of device status, scene control options, and historical data of device operation. The smart central control screen has a built-in microphone and sensor. The microphone has a built-in voice recognition module. The sensor is used to capture user gestures. The smart central control screen supports multiple interaction methods, including touch, voice recognition, and gesture sensing. Users can control and manage home appliances through touch, voice recognition, and gesture sensing. The multi-mode interaction design can be used alone or in combination to enhance the user experience.

[0022] Its smart central control screen integrates a large-size high-definition touch screen as the interactive interface between the user and the smart home system. The large-size high-definition touch screen is used to display the real-time status of all smart devices in the home, including signal strength, device switches and working modes;

[0023] The reconfigurable smart surface RIS module is composed of multiple programmable phased array units. The array units can change the reflection phase and direction of the signal through voltage adjustment. The reconfigurable smart surface RIS module is installed in the housing of the smart central control screen, the wall and ceiling of the home, as the core component for signal transmission optimization;

[0024] The reconfigurable intelligent surface RIS module controls the propagation path of wireless signals by changing the phase distribution of the phased array units on the surface and actively adjusts the reflection angle of the signals. This can effectively enhance the coverage of wireless signals, avoid signal attenuation caused by obstacles such as walls and furniture, and provide a stable signal source for smart devices.

[0025] The signal optimization and dynamic adjustment module works in conjunction with the reconfigurable intelligent surface RIS module to monitor the signal transmission status between home devices in real time, and adjust the working status of the reconfigurable intelligent surface RIS module based on environmental changes to optimize the signal transmission path. The environmental changes include the impact of device movement and physical obstacles. The signal optimization and dynamic adjustment module detects the impact of changes in the physical environment on signal propagation through distance sensors or laser ranging;

[0026] The signal optimization and dynamic adjustment module uses channel state estimation technology to dynamically calculate the optimal signal propagation path between devices, and adjusts the phase array in the reconfigurable intelligent surface RIS module to ensure that the wireless signal can be efficiently transmitted to the target device to avoid signal interference or conflict. For example, when the device signal is attenuated, the reconfigurable intelligent surface RIS module will adjust the signal reflection direction to guide the signal around obstacles and improve the signal strength.

[0027] The multi-device management and control module supports the centralized management and control of all home devices in the smart home, including but not limited to smart lighting, audio, air conditioning and security cameras. Users can turn on and off home devices and adjust the brightness and temperature through the smart central control screen;

[0028] The multi-device management module connects all smart home devices through the wireless communication capabilities of the smart central control screen, and controls the devices according to user instructions or preset scene modes. It can intelligently identify devices with different protocols and optimize signal transmission between home devices through RIS technology to ensure the stability and timeliness of home device responses. For example, when users turn on the TV and audio equipment, the reconfigurable smart surface RIS module will avoid signal interference between devices and achieve a smooth audio and video playback experience;

[0029] The energy consumption management module optimizes the overall energy consumption performance of the system by monitoring the operating status and energy consumption data of each smart home device and combining the dynamic adjustment function of the reconfigurable intelligent surface RIS module. At the same time, by analyzing the usage frequency and working mode of home appliances, it intelligently adjusts the power output of home appliances and reduces unnecessary signal transmission. By optimizing the signal transmission path and reducing the power consumption of devices when idle, it can significantly save energy. For example, when no one is using them at night, the system will put some devices into low-power mode and reduce the signal transmission load to further reduce energy consumption. In addition, the real-time energy consumption information of each device will be displayed on the smart central control screen, and users can view the current power consumption and historical power consumption records of the device through the interface.

[0030] The present invention integrates a reconfigurable intelligent surface RIS module on the smart central control screen, and uses the reconfigurable intelligent surface RIS technology to reflect, refract or scatter signals by adjusting the phase and amplitude, so as to optimize the wireless signal transmission path between smart devices in the home environment in real time, thereby improving the signal coverage, enhancing the communication quality, ensuring the stable connection of various home devices, and solving the signal problems encountered in the current smart home system. In addition, it also integrates smart device management, interactive control, scene mode setting and energy consumption optimization functions to provide users with a convenient and stable smart home control experience.

[0031] When using this embodiment, the user inputs a control command, such as touch control, voice control or gesture control, which is converted into a standardized control signal by the command parsing module of the smart central control screen. The user can use touch, voice or gesture operation to select the home appliance to be controlled or the scene mode to be executed, and adjust the parameters of the home appliance (such as air conditioning temperature, light brightness, etc.). At the same time, the wireless communication module of the smart central control screen monitors the current status of each home appliance in real time, including whether the home appliance is online, the current operating mode of the device (such as the temperature setting of the air conditioner or the brightness of the light), and detects the hardware health status of the home appliance (such as battery power, operating stability). If there is an abnormality, an early warning will be issued on the smart central control screen to remind the user. The central control system will regularly obtain the status information of the home appliance and store this data for subsequent analysis and display;

[0032] At the same time, the signal optimization and dynamic adjustment module monitors the wireless signal strength in the home environment in real time, pays special attention to areas far away from routers or where there are interference sources, detects the impact of changes in the physical environment (such as furniture displacement, people walking, etc.) on signal propagation, and uses channel state estimation technology to detect the current wireless signal propagation quality, including signal coverage area, interference situation and data transmission rate. The collected signal propagation and environmental data are transmitted to the reconfigurable intelligent surface RIS module through the channel state estimation technology. At the same time, the signal optimization and dynamic adjustment module determines whether the current signal needs to be optimized based on whether the current signal strength meets expectations and whether there is new signal interference. After receiving the signal, the reconfigurable intelligent surface RIS module dynamically adjusts the phase and reflection angle of multiple small phased array units according to the real-time data fed back by the channel, changes the signal propagation path, and realizes signal enhancement. At the same time, as the environment changes (such as door switching, people moving), the signal optimization and dynamic adjustment module will continue to monitor the channel status. If it is detected that the signal quality decreases or the interference increases, the reconfigurable intelligent surface RIS module will adjust the signal path again to optimize the communication quality, and feed back the results of the optimization process to the main control end of the central control system in real time;

[0033] After parsing, the input device control command is encapsulated into a standard protocol packet by the central control system main control end, and the control command is sent to the target device through the optimized channel path to ensure the optimal transmission path and reduce latency and packet loss rate. At the same time, the central control system will receive a confirmation receipt from the target device to ensure that the command has been successfully transmitted and is ready to be executed. If no confirmation is received, the central control system will resend the command and try to re-optimize the signal. After receiving the control command, the target device will parse and execute the corresponding operation. For example, when the smart central control screen issues a "turn on the light" command, the lighting system will execute the light-on operation and adjust it to the specified brightness. The lighting system can monitor the execution speed and operation feedback of the device in real time to ensure the operation is completed. Timely response to operations. After the home appliance performs an operation, it will immediately feedback the current operating status to the central control system (such as the light is turned on and the brightness is set to 50%). If the device fails to perform the operation correctly (such as hardware failure, connection loss), the central control system will prompt the user and try again. At the same time, the smart central control screen will synchronously update and display the operating status of multiple devices to ensure that all devices display the same status on the smart central control screen interface. For example, the brightness of the light, the temperature of the air conditioner, the opening and closing status of the curtains, etc. will be updated on the screen in real time. If the central control system detects that the status of a device is abnormal or fails to respond to user instructions correctly, the smart central control screen will issue a prompt to remind the user to take appropriate measures;

[0034] In addition, the energy consumption management module will collect energy consumption data in real time, monitor the power consumption, operating time, idle time, etc. of each device, analyze these data, and store historical records for users to view and manage. At the same time, the energy consumption management module dynamically adjusts the power output according to the usage of the device in combination with the reconfigurable intelligent surface RIS module. For example, when the device is detected to be in an idle state, it automatically reduces the signal power or turns off certain functions to reduce energy consumption. For devices that have not been used for a long time, it can automatically enter sleep mode and suspend non-essential signal transmission and function operations to save energy. At the same time, the energy-saving mode can be set to automatically adjust the working status of multiple devices in low-power scenarios. For example, when the user leaves the room, the lights will be automatically turned off, the air-conditioning temperature will be adjusted, etc., to achieve effective energy-saving effects. At the same time, the real-time energy consumption information of each device will be displayed on the smart central control screen, and users can view the current power consumption and historical power consumption records of the device through the interface.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
