[0002] With the acceleration of the pace of modern life and the improvement of people's health awareness, sleep quality has become an important factor affecting the physical and mental health of individuals, especially the deep sleep stage is of great significance to physical recovery, memory consolidation and emotional regulation. Studies have shown that stable physiological parameters such as heart rate, blood oxygen saturation and respiratory rate, as well as comfortable ambient temperature, humidity, light and noise levels are the key to ensuring high-quality sleep. However, due to life pressure and environmental interference, many people find it difficult to obtain high-quality deep sleep, so deep sleep analysis and improvement based on physiological and environmental monitoring has become a research hotspot.

[0079] The physiological parameter acquisition module includes:

[0080] Heart rate monitoring: Use a photoelectric plethysmography sensor to collect the user's pulse signal and monitor the heart rate in real time. The sensor on the user's wrist or finger detects the change in light absorption of blood volume and calculates the heart rate value. The heart rate calculation formula is as follows:

[0081]

[0082] Where HR is the number of heart beats per minute (BPM), and RR is the time interval between adjacent heart beats in seconds. This step obtains stable heart rate data by continuously monitoring the RR interval to ensure the real-time and accuracy of the heart rate information;

[0083] Blood oxygen saturation monitoring: Use a dual-wavelength light source (such as red light and infrared light) to obtain the user's pulse blood oxygen saturation through a photoelectric sensor. The blood oxygen saturation calculation formula is as follows:

[0084]

[0085] Among them, R AC is the AC component of the arterial blood absorption signal, R DC It is a DC component. By analyzing the absorption changes of light of different wavelengths, it can accurately calculate the blood oxygen level and ensure the real-time blood oxygen data of the user.

[0086] Respiratory rate monitoring: Use the volume change sensor on the chest or abdomen to monitor the user's respiratory rate in real time. The sensor calculates the respiratory rate by detecting the volume change caused by breathing. The respiratory rate calculation formula is:

[0087]

[0088] Wherein, BR is the number of respirations per minute, n is the number of respirations during the monitoring period, and t is the duration of the monitoring period in minutes. This step ensures the real-time update of the respiratory rate data by continuously collecting changes in respiratory rhythm;

[0089] The physiological parameter acquisition module works together through the above steps to obtain the user's physiological parameter data in real time and accurately, providing comprehensive and high-precision data support for deep sleep analysis.

[0090] The environmental parameter acquisition module includes:

[0091] Room temperature monitoring: Use temperature sensors to collect indoor temperature data of the user's sleeping environment. The temperature sensors are installed in the sleeping area. By regularly collecting and recording temperature data, the accuracy and real-time nature of the temperature information are ensured. The temperature data is in degrees Celsius, which can detect temperature changes and identify ambient temperature fluctuations in a timely manner, providing a basis for improving the user's sleeping environment.

[0092] Humidity monitoring: Use humidity sensors to collect humidity data of the user's sleeping environment. The humidity sensors are installed in the sleeping area and collect environmental humidity data regularly to ensure the accuracy of humidity data and help identify humidity anomalies that may affect deep sleep.

[0093] Light intensity monitoring: Use light sensors to collect light intensity data in the user's sleeping environment. The light sensors are placed in appropriate locations to avoid interference from direct light sources. By detecting changes in light intensity in the environment and recording light intensity data, light intensity monitoring helps identify situations where light is too strong or too dark, thereby avoiding interference from poor lighting conditions on sleep stages.

[0094] Noise level monitoring steps: Use noise sensors to collect noise intensity data in the user's sleeping environment. The noise sensors are installed around the sleeping area and collect noise intensity data regularly. By monitoring the noise changes in the environment, the noise sources that disturb sleep are identified to help maintain a low-noise sleeping environment.

[0095] The environmental parameter acquisition module can comprehensively and accurately monitor the user's sleeping environment parameters in real time, providing precise environmental data support for deep sleep analysis.

[0096] The deep sleep analysis module includes:

[0097] Data preprocessing: Data cleaning and normalization of collected physiological parameters (including heart rate, blood oxygen saturation and respiratory rate) and environmental parameters (including room temperature, humidity, light intensity and noise level) to ensure data integrity and consistency, and improve the accuracy of data analysis by eliminating abnormal data and filling missing values;

[0098] Heart rate variability acquisition: Use the photoplethysmography sensor to detect the time interval between adjacent heartbeats (RR interval) and calculate the heart rate variability (HRV), including:

[0099] (1) Time domain analysis: Calculate the standard deviation of the RR interval and the root mean square index of the difference between adjacent RR intervals:

[0100]

[0101] Where RMSSD is the root mean square, SDNN is the standard deviation, and N is the total number of RR intervals. is the average value of the RR interval;

[0102] (2) Frequency domain analysis: Fast Fourier transform was performed on the RR interval sequence to extract low-frequency (LF, 0.04-0.15 Hz) and high-frequency (HF, 0.15-0.4 Hz) components. The low-frequency component reflects sympathetic nerve activity, while the high-frequency component is related to parasympathetic nerves and respiration.

[0103] Respiratory rhythm acquisition: Use a chest strap sensor to monitor the expansion and contraction of the chest or abdomen, identify each respiratory cycle, and calculate the respiratory rate;

[0104] Feature extraction: Based on the preprocessed physiological and environmental parameters, feature variables related to deep sleep are extracted, including low-frequency and high-frequency components in heart rate variability, the periodic stability of respiratory rhythm, and the influence of environmental noise and light on physiological rhythm;

[0105] Deep sleep model construction: The deep sleep model is constructed using the extracted feature variables. The model outputs the user's deep sleep evaluation value. The mathematical expression of the model is:

[0106] S deep =f(HRV,BR,Temp,Humidity,Light,Noise);

[0107] Among them, S deep is the deep sleep assessment value, HRV represents heart rate variability, BR represents breathing rate, Temp, Humidity.Light and Noise represent ambient temperature, humidity, light intensity and noise level respectively;

[0109] Assessment of deep sleep duration and quality includes:

[0110] Deep sleep stage recognition: Input the real-time monitored physiological parameters and environmental parameters into the constructed deep sleep model, and judge whether the user has entered the deep sleep stage according to the deep sleep evaluation value output by the model. If the deep sleep evaluation value exceeds the preset threshold, the user is judged to have entered the deep sleep stage and the timing starts;

[0111] Deep sleep time calculation: The time of the identified deep sleep stage is accumulated and calculated. By monitoring the duration of the deep sleep state, the total duration of the user's deep sleep in one sleep cycle is calculated. This duration data is used to measure the time characteristics of deep sleep.

[0112] Deep sleep quality assessment: Based on the total deep sleep duration, heart rate variability and respiratory rhythm stability, the user's deep sleep quality is comprehensively assessed. The sleep quality calculation formula is:

[0113] Q deep =w 1 ×HRV stability +w 2 ×BR stability +w 3 ×T deep ;

[0114] Among them, Q deep Score deep sleep quality, HRV stability and BR stability Respectively represent the stability of heart rate variability and respiratory rhythm, T deep is the deep sleep time, w 1 、w 2 and w 3 is the weight coefficient of each indicator;

[0115] Through deep sleep stage identification, time calculation and quality assessment, a multi-dimensional analysis of the user's deep sleep is achieved, providing users with scientific sleep quality feedback and data support.

The thresholds can be automatically adjusted based on the user's historical data to adapt to individual differences;

[0119] Abnormality discrimination: By comparing the real-time physiological parameters with the set thresholds, physiological abnormalities are identified. For example, when the heart rate exceeds the preset range (heart rate surge) or the blood oxygen saturation is lower than the preset threshold, it is judged as an abnormal state. The specific discrimination logic is expressed as follows:

[0120]

[0121] Among them, HR is the current heart rate, HR上限 is the upper heart rate threshold, SpO 2 is the current blood oxygen saturation, SpO 2下限 is the lower blood oxygen threshold;

[0122] Through data acquisition, threshold setting and abnormality identification steps, real-time monitoring of the user's physiological state is achieved to ensure timely response when abnormalities occur.

[0123] The anomaly detection and warning module also includes:

[0124] Anomaly confirmation: When an abnormal condition is detected, the anomaly is further confirmed through an anomaly detection algorithm to reduce false positives and ensure the accuracy of the warning. The anomaly detection algorithm includes:

[0125] (1) Abnormal persistence analysis: Calculate the duration of the abnormal state T 持续 , and judge whether it exceeds the set time threshold T 阈值 , expressed as:

[0131] (3) Trend analysis: by calculating blood oxygen saturation SpO 2 The rate of change of ΔSpO 2 Determine whether there is a continuous downward trend, expressed as:

[0134] (4) Multivariate abnormal association: Combined with multiple physiological parameters such as heart rate and blood oxygen saturation, a joint judgment is made. When the heart rate exceeds the upper threshold and the blood oxygen saturation is lower than the lower threshold, it is judged as a high-risk abnormal state, expressed as:

[0135]

[0136] Warning trigger: After confirming an abnormal condition, a warning prompt is triggered and the warning information is sent to the user end or associated devices. The warning information includes the abnormality type (such as a sudden increase in heart rate or a decrease in blood oxygen), current physiological data, and related suggestions to ensure that users are aware of their physiological status in a timely manner;

[0137] Notification sending: The warning information is sent to the user or family members through wireless communication (such as SMS, application notification, etc.).

[0139] Through abnormal confirmation, warning triggering, notification sending and record storage steps, it provides users with comprehensive health monitoring and abnormal warning functions, which helps to take effective measures in time when the user's health status becomes abnormal.

[0140] Dynamic feedback and optimization modules include:

[0141] User feedback collection: Provide a user feedback interface to allow users to provide feedback on the accuracy and effectiveness of warning information. Users mark whether the warning information is accurate or provide subjective evaluation of sleep status. Feedback data is recorded and stored in the data storage and analysis module as a basis for model optimization;

[0142] Historical data analysis: Regularly analyze the user's historical physiological parameters (such as heart rate, blood oxygen saturation, and respiratory rate) and historical environmental parameters (such as room temperature, humidity, light intensity, and noise level) to identify the changing trends of the user's sleep patterns and individual physiological characteristics. This step extracts key features through data mining and statistical analysis techniques to provide basic data for model optimization.

[0143] Model parameter adjustment: Based on user feedback, historical physiological parameters, and historical environmental parameter analysis results, the parameters of the deep sleep model are dynamically adjusted to adapt them to the physiological and environmental characteristics of individual users. The parameter adjustment uses a recursive optimization algorithm to minimize the model prediction error. The adjustment formula is as follows:

[0144]

[0145] Among them, θ new is the updated model parameter, θ old is the previous parameter value, α is the learning rate, is the gradient of the model’s loss function, used to indicate the adjustment direction;

[0146] Model Adaptation: After the deep sleep model is adjusted, an adaptive test is performed to verify whether the dynamically adjusted deep sleep model accurately reflects the user's sleep pattern and physiological characteristics. The adaptive test is based on recent real-time data to ensure that the model has good predictive ability for new data;

[0147] Application of optimization results: The dynamically adjusted deep sleep model is applied to subsequent sleep analysis and early warning judgment. The system automatically uses the adjusted model parameters for data analysis and abnormality detection to improve the accuracy of analysis and early warning;

[0148] Through user feedback collection, historical data analysis, model parameter adjustment, model adaptation and optimization result application steps, the deep sleep model is dynamically optimized, so that the system can better adapt to individual differences, improve the accuracy of deep sleep analysis and early warning, and thus more effectively improve the user's sleep quality management.
