Description

Technical Field

[0001] The present invention relates to the field of smart homes, and in particular to a smart bed system and a smart bed. Background Art

[0002] Traditional sleep environment control devices, such as electric blankets and air conditioners, cannot precisely control the micro-environmental temperature of the bed. Waking up in winter can lead to sudden temperature changes, while cooling large spaces in summer can result in excessive energy consumption. Furthermore, the enclosed sleeping environment is prone to carbon dioxide accumulation and lacks an active oxygen concentration regulation mechanism, which affects respiratory and metabolic efficiency.

[0003] Although some intelligent controls already exist, current improvement solutions mostly use the superposition of single functional modules (such as temperature control + sound insulation layer), so there is an urgent need to develop a more intelligent integrated sleep system.

The accompanying drawings are for illustration purposes only and are not to be considered as limiting the present invention. The same reference symbols are used throughout the drawings to represent the same components. In the drawings: Figure 1 A schematic block diagram showing the composition of a smart bed system provided by an embodiment of the present invention is shown.

DETAILED DESCRIPTION

[0021] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0022] In order to solve the problem of lack of a smarter sleeping mattress cover in daily life, the embodiment of the present invention provides a smart bed device, such as Figure 1 As shown, the system includes a host, a mattress, a bed frame and a bed cover: The host includes a network module, an air processing module, a data storage module and a control module. The network module is used to establish a physical connection with the Internet and the Internet of Things; The air treatment module includes a negative ion generator, an oxygen enrichment generation unit and a temperature control unit, which are used to adjust the gas composition and temperature inside the bedspread; The data storage module is used to store data set by users or sensor feedback and system logs; The control module is used to control the operation of the host, the mattress, the bed frame and the bed cover according to user settings or sensor feedback data; The mattress includes a piezoelectric sensor for detecting a user's physiological index; The foot of the bed frame can isolate vibration noise; The bed cover is made of sound insulation material and comprises a mosquito-proof and light-proof layer and a safety valve.

[0023] For example, the components of a smart bed system are divided into a main unit, a mattress, a bed frame, and a bedspread. The main unit contains four modules: a network module, an air processing module, a data storage module, and a control module. The network module is a core component of the main unit, dedicated to establishing a physical connection with the Internet and the Internet of Things. The air processing module includes a negative ion generator, an oxygen enrichment generation unit, and a temperature control unit. The data storage module is used to store user settings and sensor data, and the control module controls the operation of the air processing module based on this data. The bedspread is made of sound-insulating and shock-absorbing material, and has a mosquito-proof and light-proof layer and a safety valve. The safety valve is connected to the main unit through an electromagnetic device and automatically opens when the power is cut off to ensure air circulation.

[0024] The main unit consists of four modules. The network module is an integrated communication interface unit responsible for data transmission and connection management. The negative ion generator in the air treatment module may be used to purify the air, the oxygen enrichment unit may increase the oxygen concentration, and the temperature control unit may regulate the temperature. The data storage module stores user preferences and sensor feedback data, and the control module processes this data to adjust the operation of the air treatment module.

[0025] The Internet mentioned in the network module above refers to a global public network system that supports remote data exchange and information access between devices. The Internet of Things (IoT) refers to a dedicated network connecting physical devices (such as sensors and smart appliances) to enable collaboration and data sharing. Physical connections refer to physical links established via wired or wireless methods (such as Ethernet, Wi-Fi, or cellular networks) to ensure stable and reliable signal transmission. In principle, the network module actively detects and binds to available network signal sources through built-in communication protocols (such as TCP / IP or MQTT) and hardware interfaces (such as radio frequency chips or modems). When the system boots up, the module initiates the connection process, including authenticating network permissions, negotiating data transmission channels, and maintaining a heartbeat mechanism to monitor link status. This enables the smart bed system to access external resources (such as online services or cloud data) in real time through the internet, while also connecting to other smart devices in the IoT ecosystem (such as home automation sensors or health monitors). At the network level, this connection provides a two-way communication foundation for the entire smart bed: on the one hand, input data (such as user commands or environmental information) is transmitted to the host control module through a physical link for processing; on the other hand, output data (such as system logs or alarm signals) is pushed to external network nodes. This mechanism reduces the risk of information silos, ensures the real-time response of the system to external events, and improves the scalability and collaboration capabilities of the smart bed. The physical connection design of the network module enhances the overall intelligence level of the system, for example, by optimizing the user experience by reducing data transmission latency, and provides basic support for subsequent modules (such as data storage or control logic), avoiding system function restrictions caused by connection interruptions.

[0026] The air treatment module functions as the core environmental conditioning unit, regulating the gas composition and temperature inside the mattress cover through the following components: The negative ion generator releases negative ions (negatively charged oxygen molecules) to neutralize suspended particulate matter such as dust and bacteria in the air, purifying the air and improving breathing quality. The oxygen enrichment unit uses water electrolysis, molecular sieves, or PSA (pressure swing adsorption) technology to increase the oxygen concentration inside the mattress cover, promoting the user's metabolism and deep sleep. The temperature control unit uses a semiconductor cooling chip (bidirectional cooling and heating) or a heating wire + fan combination to precisely control the temperature inside the mattress cover according to the set temperature. For example, it can preheat the air before waking up in winter, and local cooling can reduce energy consumption in summer.

[0027] The data storage module records two types of data: user settings, such as target temperature, oxygen concentration threshold, and scheduled tasks; and sensor feedback, which stores environmental data collected by temperature, humidity, and gas sensors in real time for subsequent analysis and adaptive control.

[0028] The control module functions as the "brain" of the system, dynamically controlling the air handling modules based on stored data: The foot of the bed frame includes a vibration and noise isolation device. This isolation material can be made of high-density silicone or composite damping rubber, filled with a honeycomb structure, providing both flexibility and support. This device absorbs vibration energy from turning over and getting up, reducing the noise generated by bed shaking. It also blocks ground vibrations (such as footsteps and electrical vibrations) to improve sleep stability. The bottom surface is designed with a corrugated texture to enhance friction with the floor and prevent bed displacement.

[0029] The mattress cover's physical structure utilizes a sound-insulating and vibration-reducing composite material (e.g., a sandwich structure of sound-absorbing cotton, damping layer, and micro-perforated panels) to block external noise and absorb vibrations (e.g., reducing the transmission of bed frame sway). The mosquito- and light-repellent layer utilizes a dense mesh fabric to physically block mosquitoes, and is coated with a light-blocking coating on the outside to create a dark environment.

[0030] This technical solution enables precise control of temperature, oxygen, and humidity within a specific area of ​​the bed, compared to the wide-ranging adjustments of traditional air conditioners and electric blankets. By integrating miniaturized industrial oxygen production technology, soundproofing materials, and smart home controls, this system overcomes the limitations of single-function products. This design ensures sleep quality while also balancing safety, energy efficiency, and multifunctional scalability.

[0031] In one embodiment, the bed cover further comprises a breathing assistance module, wherein the breathing assistance module comprises a flexible airway tube and a micro air pump. The flexible air guide tube is distributed along the inner wall of the top of the bedspread and is connected to the micro air pump; The micro air pump is used to adjust the airflow intensity according to the user's breathing frequency. The micro air pump interacts with the oxygen-rich generating unit and the negative ion generator to deliver oxygen-rich negative ion air to the interior of the bedspread.

[0032] For example, the flexible airway tube is made of silicone or medical-grade TPU, offering flexibility (bendability exceeding 90°) and biocompatibility (non-irritating). Its inner wall is smooth to reduce airflow resistance. It is arranged in a U-shaped or mesh pattern along the inner wall of the mattress cover, avoiding the user's direct line of sight and preventing any sense of pressure. Micropores are pre-placed in the tube wall to ensure even airflow. It serves as a delivery channel for oxygen-enriched air, directing oxygen from the air pump to the user's head area. Its flexible structure adapts to different sleeping positions (for example, the airway tube automatically conforms to the curvature of the ceiling when sleeping on the side).

[0033] For example, the micro air pump is driven by a brushless motor, which is quieter than the ambient noise floor and supports variable frequency control. A piezoelectric sensor or infrared thermal imager under the mattress cover monitors the user's chest rise and fall in real time. If the user rolls over, causing a brief breathing disturbance, the air pump enters buffer mode (maintaining the current airflow for three seconds before re-adapting). When the user enters deep sleep (with a stable breathing rate), the air pump automatically reduces speed to reduce energy consumption.

[0034] For example, the oxygen generated by the oxygen enrichment unit is generated through molecular sieve adsorption (PSA) or water electrolysis. The oxygen concentration is increased and then transported to the air pump via a dedicated pipeline. An infrared thermal imager identifies the user's head position and controls the opening of the airway branch closest to the head (reducing the flow rate of other branches). The air pump mixes the oxygen-enriched air with the recirculated air from the mattress cover in a proportional manner, avoiding the risk of explosion caused by a pure oxygen environment while ensuring breathing comfort.

[0035] This technical solution helps patients with snoring and sleep apnea (OSA) regain spontaneous breathing by increasing oxygen flow (for example, triggering a strong airflow stimulus when no breathing is detected for 10 seconds). This oxygen-enriched environment improves blood oxygen saturation, promotes prolonged deep sleep (REM) sleep, and reduces morning fatigue. This module enables the system to transition from passive environmental regulation to active respiratory support, seamlessly integrating medical-grade respiratory assistance technology into the sleep environment while ensuring comfort and safety.

[0036] It is understood that the micro pressure sensor integrated into the airway of this application automatically switches to the backup air path and issues an alarm when a blockage is detected. It is also equipped with a supercapacitor energy storage module to keep the air pump running for at least 10 minutes after a power outage, until the safety valve is fully opened.

[0037] In one embodiment, the bed cover further includes a safety valve for automatically opening to ensure air circulation in the event of air input failure or power outage causing the electromagnetic control device to be demagnetized; the bed frame further includes a lifting device for lifting the mattress to change the posture of the human body.

[0038] The safety valve's mechanical design consists of an electromagnetic control device and a spring mechanism. When power is applied, the electromagnet closes the valve. When power is removed, the electromagnet demagnetizes, releasing the potential energy of the spring to push the valve open, ensuring air circulation in emergencies such as power outages. Furthermore, the "magnetic-mechanical dual redundancy" design ensures that even if the electromagnetic component fails, the mechanical structure can still ensure the valve is open, preventing user suffocation.

[0039] Furthermore, lifting devices are installed at the head and foot of the bed to elevate the mattress. These devices utilize stainless steel screw actuators driven by silent motors. During lifting, the mattress's built-in flexible support units (such as zoned air springs) deform synchronously, maintaining balanced pressure across the body. This design achieves a deep integration of the intelligent lifting system and vibration isolation technology.

[0040] In one embodiment, the host further includes a sleep aid module, which includes aromatherapy sleep aid, acoustic sleep aid, and visual sleep aid.

[0041] For example, the aromatherapy sleep aid system uses efficient atomization technology to transform essential oils into fine molecules, which diffuse quickly and evenly into the air, improving absorption efficiency. Multiple essential oil combination modes, such as "deep relaxation," "anxiety relief," and "memory enhancement," can be preset, with users customizing the blend ratio. By monitoring indoor air concentration in real time, the system automatically adjusts the release amount to avoid allergies or discomfort caused by overuse.

[0042] For example, acoustic sleep aid systems use active noise reduction technology to effectively isolate external noise (such as traffic and electrical appliances) to create a peaceful sleep environment. They dynamically adjust sound frequency based on sleep stages, for example, guiding light sleep into deep sleep or switching to soothing white noise before waking up.

[0043] For example, a visual sleep aid system dynamically adjusts light color temperature and brightness to simulate the natural light transition from sunset to sunrise, suppressing the interference of blue light on melatonin secretion. Light brightness and color gradually change with breathing rhythm, helping users focus on their breathing rate and alleviating pre-sleep anxiety. For those traveling across time zones or working shifts, specific light waves can be used to quickly adjust the body clock. Soft dynamic light effects (such as starlight and candlelight) reduce sympathetic nervous system activity and promote relaxation.

[0044] The above-mentioned sleep-aid module builds a complete sleep-aid chain from environmental intervention to physiological regulation through the multi-sensory coordination of smell, hearing, and vision. After the three are linked, it can cover the full cycle needs from "difficulty falling asleep" to "sleep maintenance", while taking into account the flexible adaptation of health management and life scenarios.

[0045] In one embodiment, the host further includes an AI interaction module, which includes a voice interaction unit, a smart home control unit, and a schedule management unit. The voice interaction unit receives user language through the microphone array for interaction; The smart home control unit acts as a smart home control hub device to control other smart devices; The smart home control unit arranges tasks according to user instructions; The schedule management unit triggers the waking up warm air or waking up music according to the time set by the user.

[0046] For example, the sound recognition unit utilizes a circular microphone array, symmetrically distributed around the top of the bedspread, supporting 360-degree sound source localization with an effective pickup range of 2 meters. An adaptive filtering algorithm separates human voices from background noise (such as air conditioning and traffic). A customizable low-power wake-up engine (e.g., a "bedspan assistant" wake-up word response time of <0.3 seconds) is available, with a false wake-up rate of <1 per 24 hours. Complex commands (e.g., "Raise the temperature by 2 degrees and play forest white noise at 6 a.m. tomorrow") are parsed using an NLP model, supporting contextual association (e.g., if the user says "It's too bright," the bedspread shade is automatically dimmed).

[0047] The smart home control unit is compatible with major smart home brands and can control devices including air conditioners (room temperature adjustment), humidifiers (synchronized humidity), smart curtains (linked to light shield opening and closing), smart door locks (automatically locking in sleep mode), and surveillance cameras (triggering bed cover alarms when detecting unusual movement). The central device implements a centralized management architecture that integrates hardware and software through unified protocol conversion, enabling device resource integration and intelligent scheduling. This provides foundational support for subsequent functional modules (such as user interaction and data analysis) while avoiding system fragmentation caused by decentralized control. The schedule management unit can schedule actions based on user-defined schedules. For example, if a user sets a wake-up time (e.g., 7:00 AM on a weekday), the heating system will start 30 minutes in advance (gradually increasing from 18°C ​​to 24°C) and a progressive wake-up music (gradually increasing from 40dB to 60dB) will play 10 minutes in advance. Based on historical data (e.g., if a user frequently works overtime on Wednesdays), a "deep recovery mode" may be recommended. The unit integrates with the phone's calendar to automatically identify meeting schedules. If there is a morning meeting the next day, the heating system will be triggered earlier to 6:30 AM.

[0048] With the help of the above modules, the system has achieved a leap from passive response to active service, integrating scattered smart devices into a collaborative network centered on sleep, while lowering the threshold for technology use through humanized design.

[0049] In one embodiment, the air processing module further comprises a humidity adjustment unit, wherein the humidity adjustment unit comprises a semiconductor cooling plate and an ultrasonic atomizer. The semiconductor refrigeration sheet is used for condensation and dehumidification; The ultrasonic atomizer is used to atomize and spray out purified water molecules. The host controls the operation of the semiconductor refrigeration plate and / or the ultrasonic atomizer according to feedback from the temperature and humidity sensor.

[0050] For example, a semiconductor refrigeration chip uses the Peltier effect. When DC current is applied, the cold end absorbs heat (the cooling surface temperature can drop to 5°C) and the hot end releases heat (requiring a heat sink for removal). When moist air flows over the cooling surface, the surface temperature drops below the dew point, and water vapor in the air condenses into liquid water, which is then discharged through the guide groove (dehumidification efficiency can reach 200ml / h). The cooling intensity is controlled by PWM current regulation. For example, at 70% humidity, the system operates at full power, while at 50% humidity, the system is reduced to 60% power.

[0051] For example, an ultrasonic atomizer has built-in UV-LED sterilization and reverse osmosis filters to ensure the atomized water reaches medical-grade purity. The atomization volume is adjusted by the amplitude of the piezoelectric ceramic plate.

[0052] This technical solution features a semiconductor cooling element equipped with an overcurrent fuse, which disconnects the circuit within 0.1 seconds in the event of abnormal current flow. It also automatically shuts down when the atomizer water level falls below 50ml, sending a notification to the app. When shut down, it automatically initiates a 30-minute hot air drying process to inhibit mold growth. This combines humidity control with extreme energy efficiency, perfectly meeting the unique needs of enclosed sleeping spaces while avoiding the energy waste associated with over-regulation in traditional solutions.

[0053] In one embodiment, the bed cover further comprises a sleep monitoring module, which comprises a piezoelectric sensor array, an infrared thermal imager and a physiological alarm unit. The piezoelectric sensor array is embedded in the bottom layer of the bed cover to detect the user's body movement and heart rate; The infrared thermal imager is installed on the top of the bed cover and is used to analyze sleeping posture through heat radiation distribution; The physiological alarm unit is used to trigger an alarm signal based on information from the piezoelectric sensor array and the infrared thermal imager.

[0054] For example, the piezoelectric sensor array consists of 128 miniature piezoelectric ceramic sensors embedded at preset intervals in the mattress cover's underside, forming a high-density pressure sensing matrix with a coverage area tailored to the bed's dimensions. Changes in pressure distribution identify movements such as turning over and getting up, with a resolution of 0.5cm displacement. Microvibrations caused by heartbeats are captured, and frequency band signals corresponding to heart rate ranges are extracted through Fourier transform. Adaptive filtering is used to eliminate environmental vibration interference (such as bed frame shaking), and a machine learning model is used to distinguish between users and pets (objects weighing less than 15kg trigger an ignore mechanism).

[0055] For example, the infrared thermal imager uses an uncooled microbolometer mounted in the center of the top of the bed cover, with a scanning frequency of 0.5Hz (sleep mode) to 5Hz (anomaly detection mode). It generates a thermal profile based on the difference between the body's 37°C radiation and the background temperature, identifying nine standard sleeping positions (such as fetal position and supine star position). It also tracks the nasal area and calculates respiratory rate. Image data is blurred in real time (retaining only the temperature gradient data), and the original thermal image is not stored or uploaded.

[0056] For example, the physiological alarm unit receives real-time data streams from the pressure sensor and thermal imager, and performs triple validation via an intelligent analysis engine. Examples include: immediate anomaly detection for sudden changes in heart rate (>30% fluctuation) and respiratory arrest (>30 seconds); trend warning analysis for persistent temperature rise and abnormal increases in body movement rate; and multimodal cross-validation, which combines pressure and temperature data to eliminate false alarms. For mild anomalies, such as early intervention for sleep apnea, a gentle vibration of the bed cover is used as a reminder. For moderate risks, such as sudden cardiac arrhythmia, a gradual light change and app notification are used to wake the user. For severe emergencies, such as cardiac arrest or febrile seizures, an automatic call to emergency contacts and 120 is made.

[0057] This application targets unusual events, including: Apnea Detection: When the thermal imager detects nasal temperature fluctuations that have stopped for >10 seconds and the piezoelectric data shows no chest or abdominal movement, the air pump pulse stimulation is triggered. Fall Prevention: If the piezoelectric matrix edge sensor is continuously activated (pressure >200Pa), it is determined that the body is close to the edge of the bed, and the vibration feedback unit is activated to remind the user to turn over.

[0058] With the help of the above technical solutions, the system has achieved a leap from single parameter monitoring to full-dimensional sleep analysis, integrating diagnostic capabilities into daily sleep scenes, and completely eliminating the sense of restraint of wearable devices through seamless design.

[0059] In one embodiment, the host further includes a safety module, which includes a fire warning unit and an earthquake warning unit. The fire warning unit includes a gas sensor and a temperature sensor. The gas sensor is used to detect the concentration of carbon monoxide and smoke particles. The temperature sensor is used to monitor the temperature difference between the inside and outside of the bedspread. When the detected value exceeds the fire safety threshold, an audible and visual alarm is triggered. The earthquake early warning unit is connected to a third-party earthquake early warning platform to obtain vibration frequency and amplitude, and triggers a safety unlocking instruction when the vibration frequency and amplitude are greater than the earthquake safety threshold.

[0060] Exemplarily, the fire warning unit's sensor configuration includes: Gas sensors: monitor carbon monoxide and smoke particles. An electrochemical CO sensor and laser scattering smoke detector are used. Temperature sensors: Four PT1000 platinum resistors are installed inside and outside the bed cover to calculate the temperature gradient in real time. If carbon monoxide levels are ≥50 ppm or smoke particles are ≥500 μg / m³, the LED breathing light inside the bed cover flashes red. If the temperature gradient is ≥15°C for 30 seconds and smoke particles are ≥1000 μg / m³, an audible and visual alarm is triggered, the safety valve fully opens, and location information is sent to the fire protection system. When the safety valve is fully opened, the air exchange rate inside the bed cover increases to 50 m³ / h (normal mode is 10 m³ / h), maximizing escape time.

[0061] The earthquake early warning unit includes an accelerometer array, one at each corner of the bed cover (for the X, Y, and Z axes) and two at the bed frame's fulcrum (focusing on the Z axis). The sampling frequency is normally 100Hz, increasing to 500Hz when the warning is triggered. It compares the characteristics of P-waves (longitudinal waves, high frequency and low amplitude) and S-waves (transverse waves, low frequency and high amplitude) in real time, incorporating a localized seismic wave database. A vibration frequency >2Hz and an amplitude >0.3g are considered a precursor to an earthquake of magnitude 4 or above. Upon detection of the P-wave (10-60 seconds before an earthquake) and a predicted magnitude of 5 or higher, a safety unlock command is executed, de-energizing the electromagnetic latch (assisted by redundant springs), and the bed cover's side walls automatically unfold to a 150-degree open position.

[0062] It's important to note that this application also includes: fire verification logic. When a gas sensor alarm triggers alone (e.g., a false alarm caused by kitchen fumes), it's verified by temperature gradient (if ΔT < 5°C, it's considered a false alarm). Seismic false alarm suppression uses AI to eliminate common interference (e.g., a heavy truck passing by: vibration frequency 0.5-1.5Hz, duration < 8 seconds).

[0063] This technical solution integrates decentralized functions like smoke alarms and earthquake warning apps into the sleep environment, avoiding excessive device interference. While traditional fire alarms only emit sound, this system integrates ventilation and structural deployment, creating a closed "detection-alarm-escape" loop. The earthquake unlocking mechanism prioritizes deployment to the side of the head (the user's easiest escape position), with a biomechanically validated deployment angle. This system achieves a qualitative shift from passive alarm to active protection, concentrating security capabilities within the bed itself. This provides users with crucial survival time in emergencies, while minimizing false alarm interference through a multi-dimensional verification mechanism.

[0064] In one embodiment, the host further includes a leisure module, which includes a game unit, a projection unit, a flexible screen, a vibration feedback unit, and an XR interaction unit. The game unit includes a game control interface, including USB, Type-C, BCI interface, etc. The projection unit is used to project an image onto the inner top wall of the bedspread; The flexible screen is integrated into the inner top wall of the bedspread; The vibration feedback unit is integrated into the mattress and is used to synchronize low-frequency vibrations according to the image and audio content; The XR interaction unit includes a tactile feedback array and an environmental perception unit, and is used to control the projection unit and the vibration feedback unit according to interaction information obtained by the tactile feedback array and the environmental perception unit.

[0065] For example, the design of the above-mentioned game unit interface provides the game unit with diversified, low-latency input and output channels through hardware protocol integration and signal path optimization, while reserving an expansion foundation for subsequent functional modules (such as peripheral management and biofeedback).

[0066] Exemplarily, the projection unit includes: Starry Sky Sleep Aid: Projects a dynamic Milky Way image, with brightness automatically adapting to ambient light; Game Mode: Enables motion compensation; and Meditation Aid: Projects a gradient light spot (e.g., from blue to warm yellow) in sync with your breathing rhythm.

[0067] For example, the vibration feedback unit comprises an actuator array composed of linear resonant actuators, embedded in a matrix layout within the mattress base. It supports intensity adjustment (0.1N steps). It extracts low-frequency audio signals in real time and decomposes them into vibration intensities using FFT (e.g., an explosion triggers a 15Hz / 18N impact). It also analyzes video frames using a CNN model (e.g., a gunfight corresponds to point-like vibrations, an earthquake corresponds to global vibrations), with a response latency of <50ms.

[0068] Exemplarily, the tactile feedback array can sense the following: the direction and speed of palm sliding, the level of finger pressure, and the trajectory of body movement, etc. by laying an intelligent fabric layer composed of hundreds of micro-touch sensing points on the surface of the bedspread. The environmental perception unit mainly includes: spatial scanning: identifying the layout of bed items (such as pillow position and body posture) through a 3D camera, motion capture: tracking user gesture commands (such as waving to switch scenes and clenching a fist to pause playback), and environmental adaptation: detecting indoor temperature and humidity and synchronously adjusting virtual scene parameters (such as starting the cooling layer in snowy scenes).

[0069] Specifically, this application includes viewing modes: Environment Construction: The projection unit generates a cinema dome image on the top, and blackout curtains rise on both sides of the bed to form an enclosed space. Perception Adaptation: Automatically adjusts image distortion by detecting the user's lying position through thermal imaging. It also splits the screen perspective when multiple viewers are identified (supporting two-person 3D viewing). Immersion Enhancement: Multiple areas of the bed vibrate in concert when an earthquake occurs in the film. The tactile array generates press feedback at corresponding locations on the screen when touch interaction points appear. It also includes gaming interaction modes: Virtual-Real Fusion: Projecting a virtual button / joystick generates a tactile boundary at the corresponding location of the tactile array. When the user taps the bed, vibration feedback simulates the rebound of a physical button. Dynamic Response: When a game character is injured, a tingling vibration is generated in the corresponding body area. Successfully solving a puzzle triggers a celebratory vibration combination from the bed. Safety Protection: Sensing violent movement automatically lowers the projection height to prevent collision. Detecting excessive excitement (e.g., a heart rate >120) forces the user to enter a cooling-down mode.

[0070] With the help of the above technical solutions, the system has achieved a leap from single entertainment to multi-sensory health management, combining cinema-level audio-visual experience with bedspreads.

[0071] The embodiment of the present invention also provides a smart bed control method for the above-mentioned smart bed system, such as Figure 2 As shown, the method includes: S101, obtaining user voice, heart rate variability, and body movement frequency; For example, user voice capture uses a six-microphone ring array with beamforming technology, focusing on the user's head area to effectively suppress background noise. The fundamental frequency reflects emotional agitation, speech rate reflects stress, and the formant slope is correlated with anxiety. Key words (such as "stressed" and "can't sleep") are identified through an NLP model and weighted sentiment scores are assigned.

[0072] Exemplary, heart rate variability monitoring uses a piezoelectric film sensor fused with an optical sensor.

[0073] Exemplarily, body movement frequency detection uses a three-dimensional accelerometer array to monitor the number of turns and tremor intensity.

[0074] S102, obtaining the user's emotional state based on the user's voice, heart rate variability, and body movement frequency; For example, multi-dimensional emotional state modeling aligns speech, HRV, and body motion data to a unified timestamp. Using DS evidence theory, the confidence of each modality is weighted. A three-stage hybrid model is used: CNN extracts speech spectral features. LSTM processes HRV time series data. Random forest integrates body motion frequency domain features. Emotional dimensions are mapped, ultimately outputting a two-dimensional emotional space, where: Valence: [-1, 1], 0.1 is depression, 0.9 is happiness.

[0075] Arousal: [0,1], where 0.2 is calm and 0.8 is excited.

[0076] S103: Control the host and the bed cover based on the emotional state of the user.

[0077] For example, the air conditioning module can dynamically adjust oxygen enrichment and negative ion density based on mood. It can also activate a 3D wave massage when experiencing depression. It can also project a dynamic underwater scene when experiencing high pressure. After adjustment, it can reassess mood indicators every 30 seconds. If there is no improvement, it can increase intervention intensity (e.g., increasing white noise by 5dB). It can also establish a user-specific emotional response library (e.g., if user A is allergic to sandalwood, rosemary is preferred).

[0078] With the help of the above technical solutions, the system has achieved a leap from passive response to predictive regulation, deeply integrating the biofeedback mechanism with smart home, and providing a solution for emotion-driven environmental control.

[0079] The present invention also includes: a smart bed for realizing the above-mentioned smart bed system.
