Description

Technical Field

[0001] The present invention relates to the field of smart home, and particularly to an intelligent bed system and an intelligent bed. Background Art

[0002] For traditional sleep environment regulation, devices such as electric blankets and air conditioners cannot achieve precise temperature control of the microenvironment of the bed body. There is a sudden change in temperature when getting up in winter, and high energy consumption will occur when cooling a large space in summer. Moreover, the closed sleep environment is extremely likely to accumulate carbon dioxide, lacking an active oxygen concentration regulation mechanism, which affects the respiratory metabolism efficiency.

[0003] Although there are already some intelligent controls at present, most of the current improvement schemes adopt the superposition of single-function modules (such as temperature control + sound insulation layer). Therefore, there is an urgent need to develop a more intelligent integrated sleep system. Summary of the Invention

Detailed implementation manners

[0021] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the 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. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be completely conveyed to those skilled in the art.

[0022] To solve the problem of lacking a more intelligent sleep bed cover in daily life, an embodiment of the present invention provides an intelligent bed device, as Figure 1 shown, the system includes a host, a mattress, a bed frame, and a bed cover: The host includes an air treatment module, a data storage module, and a control module. The air treatment module includes a negative ion generator, an oxygen-rich generation unit, and a temperature control unit, and is used to adjust the gas composition and temperature inside the bed cover. The data storage module is used to store data set by the user, feedback from sensors, 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 the data set by the user or feedback from sensors. The mattress includes piezoelectric sensors for detecting the physiological indexes of the user. The bed feet of the bed frame can isolate vibration and noise. The bed cover is made of sound insulation material and includes a mosquito-proof and light-shielding layer and a safety valve.

[0023] Exemplarily, the components of the intelligent bed system are divided into a host, a mattress, a bed frame, and a bed cover. The host includes three modules: an air treatment module, a data storage module, and a control module. The air treatment module further includes a negative ion generator, an oxygen-rich 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 treatment module according to these data. The bed cover part is made of sound insulation and shock absorption material, has a mosquito-proof and light-shielding layer and a safety valve, and the safety valve is connected to the host through an electromagnetic device and automatically opens when powered off to ensure air circulation.

[0024] The three modules of the host. The negative ion generator in the air treatment module may be used to purify the air, the oxygen-rich generation unit may increase the oxygen concentration, and the temperature control unit adjusts the temperature. The data storage module stores the data of user preferences and sensor feedback, and the control module processes these data to adjust the operation of the air treatment module.

[0025] The function of the above air treatment module is the core environmental regulation unit, which regulates the gas composition and temperature inside the bed cover through the following components: Negative ion generator: Releases negative ions (negatively charged oxygen molecules) to neutralize suspended particles such as dust and bacteria in the air, purify the air, and improve the breathing quality. Oxygen-rich generation unit: Enhances the oxygen concentration inside the bed cover through electrolysis of water, molecular sieve, or PSA (pressure swing adsorption) technology to promote the user's metabolism and deep sleep. Temperature control unit: Adopts a semiconductor refrigeration sheet (bidirectional cooling and heating) or a combination of heating wire + fan, and precisely regulates the temperature inside the bed cover according to the set temperature. For example, preheat the air before getting up in winter and locally cool in summer to reduce energy consumption.

[0026] The function of the above data storage module is to record two types of data: User settings: Such as target temperature, oxygen concentration threshold, and scheduled tasks. Sensor feedback: Real-time stores environmental data collected by temperature and humidity sensors, gas sensors, etc., for subsequent analysis and adaptive control.

[0027] The function of the above control module is the "brain" of the system, which dynamically controls the air treatment module according to the stored data: The bed feet part of the bed frame contains a vibration and noise isolation device. The above vibration isolation material can be made of high-density silica gel or composite damping rubber, with a honeycomb structure filled inside, having both flexibility and support. It absorbs the vibration energy when the human body turns over or gets up, reduces the noise generated by the shaking of the bed body, and can also block the vibration transmitted from the ground (such as footsteps and the vibration of electrical appliances running), improving the sleep stability. And the bottom surface is designed with corrugated textures to enhance the friction with the ground and prevent the displacement of the bed body.

[0028] The physical structure material of the bed cover part uses a sound insulation and shock absorption composite material (such as a "sound-absorbing cotton + damping layer + micro-perforated plate" sandwich structure) to block external noise and absorb vibration (such as reducing the transmission of bed frame shaking). The mosquito and light protection layer uses a dense mesh fabric to physically block mosquitoes, and the outer layer is coated with a light-shielding coating to create a dark environment.

[0029] With the above technical solutions, compared with the large-scale regulation of traditional air conditioners / electric blankets, this system realizes the refined control of temperature / oxygen / humidity for the local space of the bed body. It combines the miniaturization of industrial oxygen production technology, sound insulation materials, and smart home control, breaking through the limitations of single-function products. Through this design, while ensuring the user's sleep quality, the system also takes into account safety, energy efficiency, and multi-functional expandability.

[0030] In one embodiment, the bed cover further includes a breathing assistance module, and the breathing assistance module includes a flexible air duct and a micro air pump. The flexible air duct is distributed along the inner wall of the top of the bed cover and is connected to the micro air pump. The micro air pump is used to adjust the air flow intensity according to the user's breathing frequency. The micro air pump interacts with the oxygen-rich generation unit and the negative ion generator to deliver oxygen-rich negative ion air into the bed cover.

[0031] Exemplarily, the flexible air duct is made of silicone or medical-grade TPU material, with flexibility (bendable more than 90°) and biocompatibility (non-irritating), and has a smooth inner wall to reduce air flow resistance. It is distributed in a "U shape" or "mesh shape" along the inner wall of the top of the bed cover, avoiding the direct line of sight area of the user to avoid a sense of oppression. Micropores are preset on the pipe wall to ensure uniform diffusion of air flow. As a delivery channel for oxygen-rich air, it guides oxygen from the air pump to the user's head area, and at the same time adapts to different sleeping postures through a flexible structure (for example, when lying on the side, the air duct automatically fits and bends along the ceiling).

[0032] Exemplarily, the micro air pump is driven by a brushless motor, with a noise lower than the ambient background noise and supports frequency conversion control. Through the piezoelectric sensor or infrared thermal imager at the bottom layer of the bed cover, the chest fluctuation frequency of the user is monitored in real time. When the user turns over and causes a short-term breathing disorder, the air pump enters the buffer mode (maintaining the current air flow for 3 seconds and then re-adapting). When the user enters deep sleep (stable breathing frequency), the rotation speed is automatically reduced to reduce energy consumption.

[0033] Exemplarily, for the above interaction with the oxygen-rich generation unit, the oxygen source is that the oxygen-rich unit uses molecular sieve adsorption technology (PSA) or electrolysis of water to produce oxygen, increases the oxygen concentration, and transports it to the air pump through a dedicated pipeline. The infrared thermal imager is used to identify the position of the user's head, and the air duct branch closest to the head is controlled to open (the flow rate of other branches is reduced). The air pump mixes the oxygen-rich air and the circulated air in the bed cover in proportion to avoid the risk of combustion and explosion caused by a pure oxygen environment, and at the same time ensure breathing comfort.

[0034] With the above technical solutions, for patients with snoring and sleep apnea syndrome (OSA), by increasing the oxygen flow rate (such as triggering strong air flow stimulation when no breathing is detected within 10 seconds), it helps to restore spontaneous breathing. The oxygen-rich environment increases the blood oxygen saturation, promotes the extension of the deep sleep stage (REM), and reduces the morning fatigue. Through this module, the system realizes the leap from passive environmental regulation to active breathing support, seamlessly integrates medical-grade breathing assistance technology into the sleep scenario, and at the same time ensures comfort and safety.

[0035] It can be understood that a micro pressure sensor is integrated in the air duct of the present application. When a blockage is detected, the standby air path is automatically switched and an alarm is issued. And it is equipped with a super capacitor energy storage module, which can maintain the operation of the air pump for at least 10 minutes after power failure until the safety valve is fully opened.

[0036] In one embodiment, the bedspread further includes a safety valve, which is used to automatically open to ensure air circulation in the case of an air input failure or power outage that causes the electromagnetic control device to demagnetize; the bed frame further includes a lifting device, which is used to lift the mattress to change the posture of the human body.

[0037] The mechanical design of the safety valve consists of an electromagnetic control device and a spring mechanical structure. When powered on, the electromagnet attracts and closes the valve; when powered off, the electromagnet demagnetizes, and the spring releases potential energy to push open the valve, ensuring air circulation in case of emergencies (such as power outages). At the same time, a "magnetic-mechanical dual redundancy" design is adopted. Even if the electromagnetic components fail, the valve can still be opened through the mechanical structure to prevent users from suffocating.

[0038] Furthermore, lifting devices are provided at the head and tail of the bed to lift the mattress. A silent motor can be used to drive a stainless steel screw push rod. When lifting, the flexible support units (such as sectional air springs) inside the mattress deform synchronously to keep the pressure on each part of the human body balanced. Based on the above design, a deep integration of the intelligent lifting system + vibration isolation technology is achieved.

[0039] In one embodiment, the host further includes a sleep aid module, and the sleep aid module includes aromatherapy sleep aid, acoustic sleep aid, and visual sleep aid.

[0040] Exemplarily, the aromatherapy sleep aid system converts essential oils into delicate molecules through high-efficiency atomization technology, quickly and evenly diffuses them into the air, and improves the absorption efficiency. Multiple essential oil combination modes can be preset, such as "deep relaxation", "anxiety relief", "memory enhancement", and users can customize the mixing ratio. By real-time monitoring the indoor air concentration, the release amount is automatically adjusted to avoid allergies or discomfort caused by overuse.

[0041] Exemplarily, the acoustic sleep aid system effectively isolates external noises (such as traffic noise and electrical appliance operation sounds) through active noise reduction technology to create a quiet sleep environment. The sound frequency is dynamically adjusted according to the sleep stage. For example, it guides into deep sleep in the light sleep stage or switches to soothing white noise before waking up.

[0042] Exemplarily, the visual sleep aid system dynamically adjusts the light color temperature and brightness, simulates the natural light change from sunset to sunrise, and inhibits the interference of blue light on melatonin secretion. The light brightness and color gradually change with the breathing rhythm to help users focus on the breathing frequency and relieve pre-sleep anxiety. For travelers crossing time zones or shift workers, the biological clock is quickly adjusted through specific light waves. The use of soft dynamic light effects (such as starlight and candlelight) reduces the activity of the sympathetic nerve and assists in entering a relaxed state.

[0043] The above sleep aid module constructs 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 health management and the flexible adaptation of life scenarios.

[0044] In one embodiment, the host further includes an AI interaction module, and the AI interaction module includes a voice interaction unit, a smart home control unit, and a schedule management unit. The voice interaction unit receives user language through a microphone array for interaction. The smart home control unit makes task arrangements according to user instructions. The schedule management unit triggers the wake-up warm air or wake-up music according to the time set by the user.

[0045] Exemplarily, the above voice recognition unit uses an annular microphone array, which is symmetrically distributed centered on the top of the bedspread, supports 360° sound source localization, and has an effective sound pickup distance of 2 meters. The human voice and background noise (such as air conditioner noise, traffic flow outside the window) are separated by an adaptive filtering algorithm. A low-power wake-up engine can be customized (such as the response time of the wake-up word "bedspread assistant" < 0.3 seconds), and the false wake-up rate < 1 time / 24 hours. Complex instructions are parsed based on the NLP model (such as "raise the temperature by 2 degrees and play forest white noise at 6:00 tomorrow morning"), and context association is supported (if the user says "it's too bright", the light-shielding layer of the bedspread is automatically dimmed).

[0046] The above smart home control unit is compatible with mainstream smart home brands, and the device types that can be controlled include: air conditioner (adjust the room temperature), humidifier (synchronize the humidity), smart curtain (link the opening and closing of the light-shielding layer), smart door lock (automatically lock in sleep mode), and surveillance camera (trigger the bedspread alarm when abnormal movement is detected).

[0047] The above schedule management unit can perform actions according to the user's preset schedule. For example: if the user presets an event (such as getting up at 7:00 on weekdays), the warm air is started 30 minutes in advance (gradually rising from 18°C to 24°C), and the progressive wake-up music is played 10 minutes in advance (gradually increasing from 40dB to 60dB). According to historical data (such as the user often works overtime on Wednesdays), the "deep recovery mode" is recommended. It is linked with the mobile phone calendar to automatically identify the meeting schedule. If there is an early meeting the next day, the wake-up warm air is triggered at 6:30 in advance.

[0048] With the above modules, the system realizes the leap from passive response to active service, integrates scattered smart devices into a collaborative network centered on sleep, and at the same time reduces the technical usage threshold through user-friendly design.

[0049] In one embodiment, the air treatment module further includes a humidity adjustment unit, and the humidity adjustment unit includes a thermoelectric cooler and an ultrasonic atomizer. The thermoelectric cooler is used for condensation dehumidification; The ultrasonic atomizer is used to atomize and eject purified water molecules, The host controls the operation of the thermoelectric cooler and / or the ultrasonic atomizer according to the feedback of the temperature and humidity sensor.

[0050] Exemplarily, based on the Peltier effect, when direct current is applied to the thermoelectric cooler, the cold end absorbs heat (the temperature of the cooling surface can be reduced to 5°C), and the hot end releases heat (which needs to be discharged in cooperation with a radiator). When humid air flows through the cooling surface, the surface temperature is lower than the dew point temperature, and the water vapor in the air condenses into liquid water and is discharged through the diversion groove (the dehumidification efficiency can reach 200 ml / h). The cooling intensity is controlled by PWM to adjust the current. For example, when the humidity is 70%, it operates at full power, and when the humidity is 50%, the frequency is reduced to 60% of the power.

[0051] Exemplarily, the ultrasonic atomizer. It is equipped with a built-in UV-LED sterilizer and a reverse osmosis filter element to ensure that the atomized water reaches medical-grade purity. The atomization amount is adjusted by the amplitude of the piezoelectric ceramic sheet.

[0052] In the above technical solution, the thermoelectric cooler is equipped with an overcurrent fuse, which cuts off the circuit in 0.1 second in case of abnormal current. When the water level in the atomizer is lower than 50 ml, it automatically shuts down and pushes an APP reminder. When the machine stops, it automatically starts hot air drying for 30 minutes to inhibit the growth of mold. It realizes the combination of humidity control and extreme energy efficiency, perfectly adapts to the special needs of a closed sleep space, and at the same time avoids the energy waste caused by excessive adjustment in the traditional solution.

[0053] In one embodiment, the bedspread further includes a sleep monitoring module, and the sleep monitoring module includes 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 bedspread for detecting the body movement and heart rate of the user; The infrared thermal imager is installed on the top of the bedspread for analyzing the sleep posture through the thermal radiation distribution; The physiological alarm unit is used to trigger an alarm signal based on the information of the piezoelectric sensor array and the infrared thermal imager.

[0054] Exemplarily, the above piezoelectric sensor array consists of 128 micro piezoelectric ceramic sensors embedded in the bottom layer of the bedspread at a preset interval to form a high-density pressure sensing matrix, and the coverage area is adapted to the size of the bed. Actions such as turning over and getting up are identified through the change of pressure distribution, and the displacement resolution is 0.5 cm. The micro-vibration caused by the heartbeat is captured, and the frequency band signal is extracted through Fourier transform, corresponding to the heart rate range. Adaptive filtering is used to eliminate environmental vibration interference (such as the shaking of the bed frame), and a machine learning model is combined to distinguish between the user and the pet (the trigger ignore mechanism for objects with a weight < 15 kg).

[0055] Exemplarily, the above infrared thermal imager uses an uncooled microbolometer and is installed at the center of the top of the bedspread. The scanning frequency ranges from 0.5 Hz (sleep mode) to 5 Hz (abnormality detection mode). Thermal profiles are generated based on the temperature difference between the 37°C radiation of the human body and the background, and nine standard sleeping postures (such as the fetal position and the starfish position) are recognized. The breathing rate is calculated by tracking the nasal area. The image data is processed in real time with blurring (only the temperature gradient data is retained), and the original thermal map is not stored or uploaded.

[0056] Exemplarily, the above physiological alarm unit receives the data streams from the pressure sensor and the thermal imager in real time and performs triple verification through an intelligent analysis engine. The following are examples: Instant abnormality detection: sudden change in heart rate (>30% fluctuation), apnea (>30 seconds); Trend warning analysis: continuous increase in body temperature, abnormal increase in body movement frequency; Multimodal cross-verification: combining pressure and temperature data to eliminate false alarms. For mild abnormalities, such as early intervention for sleep apnea, a slight vibration reminder of the bedspread is given; for moderate risks, such as sudden arrhythmia, a gradual change in lighting for waking up + APP push is carried out; for severe critical conditions, such as cardiac arrest / hyperpyretic convulsion, an automatic call to the emergency contact + 120 is made.

[0057] This application is directed to abnormal events, including: Apnea detection: When the thermal imager detects that the temperature fluctuation of the nose stops for more than 10 seconds and there is no chest and abdomen movement in the piezoelectric data, a gas pump pulse stimulation is triggered. Fall prevention: If the edge sensor of the piezoelectric matrix is continuously activated (pressure > 200 Pa), it is determined that the body is close to the edge of the bed, and then the vibration feedback unit is activated to remind the user to turn over.

[0058] By means of the above technical solutions, the system realizes the leap from single-parameter monitoring to full-dimensional sleep analysis, integrates the diagnostic ability into the daily sleep scenario, and at the same time completely eliminates the sense of restraint of wearable devices through a non-intrusive design.

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

[0060] Exemplarily, the sensor configuration of the fire warning unit includes: Gas sensor: monitors carbon monoxide and smoke particles. Electrochemical CO sensor + laser scattering smoke detector is used. Temperature sensor: 4 PT1000 platinum resistors are installed inside and outside the bedspread to calculate the temperature gradient in real time. When carbon monoxide ≥50ppm or smoke particles ≥500μg / m³, the LED breathing light in the bedspread is triggered to flash (red). When the temperature gradient is ≥15℃ for 30 seconds and the smoke particles are ≥1000μg / m³, the sound and light alarm + safety valve is fully opened + positioning information is pushed to the fire protection system. When the safety valve is fully opened, the ventilation volume inside the bedspread is increased to 50m³ / h (10m³ / h in normal mode) to strive for golden escape time.

[0061] The above-mentioned earthquake early warning unit includes: an acceleration sensor group, one group deployed at each of the four corners of the bed cover (XYZ three axes), and two groups at the fulcrum of the bed frame (focusing on the Z axis). Sampling frequency: 100Hz in normal state, increased to 500Hz when the early warning is triggered. By real-time comparison of the characteristics of P waves (longitudinal waves, high frequency and low amplitude) and S waves (transverse waves, low frequency and high amplitude), combined with the localized seismic wave database. When the vibration frequency is >2Hz and the amplitude is >0.3g, it is judged as a precursor to an earthquake of magnitude 4 or above. After the P wave is detected (10-60 seconds before the earthquake), if the magnitude is predicted to be ≥5, the safety unlocking command is executed, the electromagnetic lock is powered off and released (assisted by redundant springs), and the side walls of the bed cover are automatically unfolded to a 150° open state.

[0062] It should be noted that this application also includes: fire verification logic, when the gas sensor alarms alone (such as kitchen fume false trigger), it is verified by temperature gradient (if ΔT < 5°C, it is judged as a false alarm). Earthquake false positive suppression, using AI to eliminate common interference (such as heavy truck passing: vibration frequency 0.5-1.5Hz, duration <8 seconds).

[0063] Through the above technical solutions, scattered smoke alarms, earthquake warning apps and other functions are integrated into the sleeping scene to avoid excessive interference from equipment. Traditional fire alarms only make sounds, while this system links ventilation + structural deployment to form a "detection-alarm-escape" closed loop. The earthquake unlocking structure preferentially deploys the head side area (the direction where users are most likely to escape), and the deployment angle has been verified by biomechanics. The system has achieved a qualitative change from passive alarm to active protection, concentrating security capabilities into the bed space, buying critical survival time for users in sudden disasters, and minimizing false alarm interference through a multi-dimensional verification mechanism.

[0064] In one embodiment, the host further includes a leisure module, wherein the leisure module includes a projection unit, a flexible screen, a vibration feedback unit and an XR interaction unit. 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 environment perception unit, and is used to control the projection unit and the vibration feedback unit according to interaction information acquired by the tactile feedback array and the environment perception unit.

[0065] Exemplarily, the projection unit includes: Starry sky sleep aid: projecting dynamic Milky Way images, with brightness automatically adapted to ambient light. Game mode: turning on motion compensation. Meditation aid: projecting gradient light spots (e.g., from blue to warm yellow) in accordance with breathing rhythm.

[0066] Exemplarily, the vibration feedback unit includes an actuator array composed of linear resonant actuators, which is embedded in the bottom layer of the mattress in a matrix layout. It supports intensity adjustment (0.1N step). It extracts audio low-frequency signals in real time and decomposes them into vibration intensity through FFT (such as explosion scenes triggering 15Hz / 18N impact). It analyzes video frames based on the CNN model (such as point vibrations corresponding to gun battles, and global vibrations corresponding to earthquake scenes), and the response delay is <50ms.

[0067] Exemplarily, the above-mentioned tactile feedback array, by laying an intelligent fabric layer composed of hundreds of micro-touch sensing points on the surface of the bedspread, can sense: the direction and speed of palm sliding, the level of finger pressure and the trajectory of body movement, etc. The above-mentioned environmental perception unit mainly includes: spatial scanning: identifying the layout of bed items (such as pillow position, body posture) through a 3D camera, motion capture: tracking user gesture commands (such as waving to switch scenes, clenching a fist to pause playback), environmental adaptation: detecting indoor temperature and humidity and synchronously adjusting virtual scene parameters (such as starting the cooling layer in snowy scenes).

[0068] Specifically, the present application includes viewing modes: Environment construction: the projection unit generates a cinema dome image at the top, and blackout curtains are raised on both sides of the bed to form a closed space. Perception adaptation: the user's lying position is detected by thermal imaging to automatically adjust the image distortion, and the screen perspective is split when multiple people are identified to watch the movie (supporting two-person 3D viewing). Immersion enhancement: when an earthquake occurs in the film, the bed vibrates in multiple areas in a linked manner, and when a touch interaction point appears on the screen, the corresponding position of the tactile array generates a press feedback. It also includes a game interaction mode: Virtual and real fusion: when the projection displays a virtual button / joystick, the corresponding position of the tactile array generates a tactile boundary, and when the user slaps the bed surface, the vibration feedback simulates the rebound of the physical button. Dynamic response: when the game character is injured, the corresponding body area generates a tingling vibration, and when the puzzle is solved successfully, the bed releases a celebratory vibration combination. Safety protection: when violent movements are sensed, the projection height is automatically lowered to prevent collisions, and when excessive excitement is detected (for example, heart rate>120), it is forced to enter the calm mode.

[0069] With the above technical solution, the system realizes the leap from single entertainment to multi-sensory health management, combining the theater-level audio-visual experience with the bedspread.

[0070] The embodiment of the present invention also provides an intelligent bed control method for the above intelligent bed system, as Figure 2 shown, the method includes: S101. Obtain the user's voice, heart rate variability, and body movement frequency; Exemplarily, the user voice is collected using a 6-microphone circular array, which supports beamforming technology, focuses on the user's head area, effectively suppresses background noise, the fundamental frequency reflects the degree of emotional excitement, the speech rate reflects the stress index), and the formant slope is related to anxiety. Identify keywords (such as "stressed", "can't sleep") through the NLP model and weight the emotional score.

[0071] Exemplarily, for heart rate variability monitoring, a piezoelectric film sensor is fused with an optical sensor.

[0072] Exemplarily, the body movement frequency is detected using a three-dimensional accelerometer array to monitor the number of turns and tremor intensity.

[0073] S102. Obtain the user's emotional state based on the user's voice, heart rate variability, and body movement frequency; Exemplarily, for multi-dimensional emotional state modeling, align the voice, HRV, and body movement data to a unified timestamp. Adopt the D-S evidence theory to weight the confidence of each modality. Through a three-stage hybrid model: CNN extracts the voice spectrum features. LSTM processes the HRV time series data. Random forest integrates the body movement frequency domain features. Map the emotional dimension: finally output a two-dimensional emotional space, where: Valence (pleasure degree): [-1, 1], 0.1 is depression, and 0.9 is pleasure.

[0074] Arousal (arousal degree): [0, 1], 0.2 is calm, and 0.8 is excited.

[0075] S103. Control the host and the bedspread based on the user's emotional state.

[0076] Exemplarily, for the above air treatment module: dynamically adjust the oxygen-rich concentration and negative ion density according to the emotion. Start the 3D wave massage in the depressive state. Project a dynamic underwater scene under high pressure. Re-evaluate the emotional index every 30 seconds after regulation. If it is not improved, increase the intervention intensity (such as increasing the white noise by 5 dB). Establish a user-specific emotion coping library (such as user A is sensitive to sandalwood, and rosemary is preferentially used).

[0077] With the above technical solution, the system has achieved a leap from passive response to predictive adjustment, deeply integrating the biofeedback mechanism with smart home and providing a solution for emotion-driven environmental control.
