Description

Technical Field

[0001] This invention relates to the field of sleep-aid regulation data processing technology, and in particular to a photoacoustic closed-loop data processing method and system for regulating sleep disorders. Background Technology

[0002] With the development of sleep health management, wearable monitoring devices, and smart home devices, the auxiliary regulation of sleep disorders is gradually shifting from simple reminders and fixed music playback to methods based on user status recognition and automatic adjustment. For users who have difficulty falling asleep, have long periods of light sleep, are prone to waking up at night, or have unstable sleep rhythms, relying solely on fixed sleep-aid music, ordinary lights, or environmental cues is often insufficient to adapt to the actual changes in the user's state before sleep, during sleep transition, and after brief awakenings at night.

[0003] For example, in home sleep aid scenarios, existing devices typically include sound-emitting components and low-brightness light-emitting components. The sound-emitting components can be used to play white noise, natural sounds, soft music, or rhythmic cue sounds; the light-emitting components are mainly used for pre-sleep relaxation, sleep guidance, or gentle light soothing after brief nighttime awakenings, such as emitting warm-colored gradient light, breathing light, or low-intensity guiding light, rather than continuously stimulating strong light during the user's stable sleep phase.

[0004] Current light and sound-based sleep aids typically acquire data such as the user's brainwaves, heart rate, respiration, body movement, environmental noise, and device usage status through EEG acquisition devices, wearable devices, bedside sensors, or mobile terminals. Based on this data, they determine whether the user is awake, in a transitional sleep state, in light sleep, in deep sleep, or experiencing brief awakenings. Subsequently, the device adjusts the sound type, volume, and duration, as well as the brightness, color temperature, and gradual change rhythm of the sleep-aid light according to preset rules, thereby providing non-invasive assistance to the user.

[0005] However, during the transition to sleep and light sleep stages, a user's sleep state is prone to slight fluctuations, such as turning over, changes in breathing, brief body movements, loosening of earpieces, or environmental noise disturbances. These changes do not necessarily indicate that the user has truly woken up, but they can cause abnormal fluctuations in collected data such as EEG, heart rate, and body movement within a short period. If the data is statistically analyzed according to a fixed time window, and sleep stages are directly judged based on data changes within a certain time period, it is easy to misinterpret normal fluctuations in sleep onset as awakening, or to mistake short-term disturbances for genuine changes in sleep state. This will lead to a mismatch between the actual output results and the user's current state, which may actually affect the user's ability to continue falling asleep or maintain a stable light sleep state.

[0006] Furthermore, users exhibit significant differences in their sensitivity to sound and light. Some users are more sensitive to sound, while others are more sensitive to light; the same user may also experience different sleep responses on different days due to fatigue levels, changes in sleep patterns, or environmental changes. If sound and light parameters are adjusted based on general sleep stages, fixed rules, or historical averages, it is often difficult to determine whether a particular sound and light adjustment is truly effective for the current user, making it difficult to establish a reliable basis for adjustment and thus affecting the accuracy and adaptability of sleep disorder assisted regulation. Summary of the Invention

[0007] Therefore, embodiments of the present invention provide a photoacoustic closed-loop data processing method and system for regulating sleep disorders. The technical solution is as follows: On the one hand, a photoacoustic closed-loop data processing method for regulating sleep disorders is provided, which includes: S1: Acquire the photoacoustic output data and user usage data of the photoacoustic adjustment device during the current sleep adjustment cycle. After the output status is identified, the data is collected in a time sequence to form photoacoustic adjustment status data.

[0008] S2, establish a state matching matrix based on photoacoustic adjustment state data to establish the correspondence between photoacoustic output and user response, and generate the corresponding state when the state matching matrix meets the preset state matching conditions; the corresponding state includes a first corresponding state representing stable output after sleep and weakened user response, a second corresponding state representing sleep guidance and active user use, and a third corresponding state representing readjustment after a short interruption.

[0009] S3, when the first corresponding state is determined, then the asynchronous coupling parameters are generated based on the matching results between the light output, sound output and user response weakening in the state matching matrix, so as to reduce the degree of synchronous linkage between the light output and the sound output.

[0010] S4. When the second or third corresponding state is determined, a synchronization coupling parameter is generated based on the matching result corresponding to the sleep guidance response or readjustment response in the state matching matrix, so that the luminescence change process and the vocalization soothing process are synchronized.

[0011] On the other hand, a photoacoustic closed-loop data processing system for sleep disorder regulation is provided, which includes: The photoacoustic status collection module acquires the photoacoustic output data and user usage data of the photoacoustic adjustment device during the current sleep adjustment cycle. After the output status is identified, the data is collected in a time sequence to form photoacoustic adjustment status data.

[0012] The state matching generation module establishes a state matching matrix based on the photoacoustic adjustment state data to establish the correspondence between photoacoustic output and user response, and generates the corresponding state when the state matching matrix meets the preset state matching conditions.

[0013] When the asynchronous coupling processing module is determined to be in the first corresponding state, it generates asynchronous coupling parameters based on the matching results between the light output, sound output and user response weakening in the state matching matrix, so as to reduce the degree of synchronous linkage between the light output and the sound output.

[0014] The synchronization coupling processing module generates synchronization coupling parameters based on the matching results corresponding to the sleep guidance response or readjustment response in the state matching matrix when the second or third corresponding state is determined, so as to synchronize the emission change process with the vocalization soothing process.

[0015] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: 1. This invention first acquires photoacoustic output data and user usage data generated by the photoacoustic adjustment device during the current sleep adjustment cycle, and forms photoacoustic adjustment state data through output state identification and time-series aggregation; then, it establishes a state matching matrix between photoacoustic output and user usage response, and generates a first corresponding state, a second corresponding state, or a third corresponding state when preset state matching conditions are met, thereby distinguishing different adjustment scenarios such as post-sleep stabilization, sleep guidance, and short-term readjustment, and improving the targeting of state identification; when determined to be the first corresponding state, asynchronous coupling parameters are generated based on the matching results between light output, sound output, and weakened user response, reducing the degree of synchronous linkage between light and sound, and reducing continuous stimulation interference in the post-sleep stabilization stage; when determined to be the second or third corresponding state, synchronous coupling parameters are generated based on the sleep guidance response or readjustment response, so that the light change process and the sound soothing process are synchronously matched, improving the reliability of the correlation processing of photoacoustic output data and user usage response data in the process of sleep disorder adjustment.

[0016] 2. By dividing the current sleep regulation cycle into multiple continuous collection units according to preset time intervals, photoacoustic output data and user usage data have a unified temporal basis. Then, based on the differences in light emission and sound emission parameters between adjacent collection units, the changes in light emission and sound emission are determined respectively. The usage response interval is determined by combining the time difference between the user's operation time and the most recent photoacoustic output change time, thus establishing a temporal correlation between photoacoustic changes and user responses. When both the changes in light emission and sound emission reach their corresponding change thresholds and the usage response interval meets the conditions for continuous use, a sleep guidance state item is generated, which helps identify the user's ongoing guidance. When both the changes in light emission and sound emission are small, a post-sleep stable state item is generated, which helps identify a stable phase with low interference and weak response. When the user pauses and restarts or closes and reopens within a short response interval, a short-term re-sleep state item is generated, which helps identify readjustment needs after a short interruption. Other situations are marked as pending matching state items, and relevant parameters are retained to provide a basis for continuous state judgment in the next collection unit.

[0017] 3. First, based on the sleep guidance state data, extract the changes in light emission, sound emission, and usage response intervals within each collection unit, and determine the light emission reduction state, sound emission reduction state, and continuous use state accordingly. This allows for a unified representation of the sound and light changes during the sleep guidance process and the user's continuous usage behavior. Then, using the collection units as matrix rows and the corresponding state items as matrix columns, fill in the light emission changes, sound emission changes, and usage response intervals to form a sleep guidance matching matrix, thus clearly reflecting the correspondence between the gradual reduction of sound and light and the user's continuous acceptance of guidance. Finally, following a similar construction method, form a post-sleep stability matching based on post-sleep stability state data. The matrix is ​​used to characterize the relationship between low-perception light emission, low-disturbance sound emission, and weakened user response, which is helpful for identifying the low-disturbance state in the post-sleep stabilization stage. At the same time, a re-sleep matching matrix is ​​formed based on short-term re-sleep state data, thereby reflecting the relationship between user re-operation and sound and light soothing callback. Finally, the light emission state item, sound emission state item, and user use response state item in each matching matrix are read and compared with preset matching conditions item by item to generate the first corresponding state, the second corresponding state, or the third corresponding state, so that the post-sleep stabilization, sleep guidance, and short-term readjustment scenarios can be distinguished and processed, improving the reliability of light and sound closed-loop data matching and state generation.

[0018] 4. In the first corresponding state, the matrix items corresponding to low-perception light emission, low-disturbance sound emission, and response weakening are read from the post-sleep stable matching matrix, and the light emission maintenance deviation, sound emission maintenance deviation, and response weakening duration parameters are calculated so that whether there is still synchronous interference in the sound and light output during the post-sleep stable stage can be quantitatively judged. Then, combined with the change direction, change amplitude, and synchronization duration of the light emission and sound emission deviations in adjacent collection units, the degree of synchronous coupling between light emission output and sound emission output is determined. When the degree of synchronous coupling exceeds the allowable range of low disturbance during sleep, the light emission suppression level, sound emission maintenance level, and sound and light linkage release level are adjusted. The level combination that meets the low disturbance requirement is used as the asynchronous coupling parameter, thereby reducing the sound and light synchronous stimulation during the post-sleep stage. In the second or third corresponding state, the binding parameters of light emission, sound emission, and user response are read from the sleep guidance matching matrix or the re-sleep matching matrix, and the synchronization start deviation, synchronization change deviation, and synchronization duration deviation are calculated respectively. Based on this, the start correction amount, change correction amount, and duration correction amount are generated to ensure that the light emission change and sound soothing are matched in terms of start timing, change trend, and duration, thereby improving the reliability of photoacoustic closed-loop parameter generation in sleep guidance and short-term readjustment scenarios.

Detailed Implementation

[0021] The technical solution of the present invention will now be described with reference to the accompanying drawings.

[0022] In embodiments of the present invention, words such as "exemplarily," "for example," etc., are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" in the present invention should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the word "exemplary" is intended to present the concept in a concrete manner. Furthermore, in embodiments of the present invention, the meaning expressed by "and / or" can be both, or either one.

[0023] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] The embodiments of the present invention provide, as follows Figure 1 The flowchart shown is for a photoacoustic closed-loop data processing method for sleep disorder regulation. The processing flow of this method may include the following steps: S1 includes: acquiring photoacoustic output data and user usage data generated by the photoacoustic adjustment device during the current sleep adjustment cycle, and performing time-series aggregation after output status identification to form photoacoustic adjustment status data. Photoacoustic output data includes light output data and sound output data. Light output data includes one or more of the following: light intensity, color temperature, light emission mode, start and end time of the gradient state, and duration of the gradient state. Sound output data includes one or more of the following: sound volume, sound type, playback rhythm, and start and end time of playback. User usage data includes user actions on the photoacoustic adjustment device, such as turning it on, turning it off, pausing, adjusting brightness, adjusting volume, switching modes, and the corresponding operation times. The current sleep adjustment cycle can be the time period from when the user starts the photoacoustic adjustment device to when the device stops adjusting, or it can be a time period automatically generated by the device according to a preset nighttime working period.

[0025] Specifically, the current sleep regulation cycle is divided into multiple consecutive aggregation units according to a preset time interval. The preset time interval can be determined during the device initialization phase based on the sampling frequency of the photoacoustic adjustment device, the control refresh cycle, and the user's commonly used adjustment duration, or it can be updated based on historical usage records. For example, in a home-based sleep aid scenario, every 30 seconds, 1 minute, or 2 minutes can be considered as an aggregation unit, allowing the light output, sound output, and user operations to fall into different aggregation units in chronological order.

[0026] For the i-th collection unit, read the average luminance, average color temperature, and luminance mode within that unit, and read the corresponding average luminance, average color temperature, and luminance mode within the (i-1)-th collection unit. The luminance change can be obtained by adding the luminance change, color temperature change, and mode change components. Specifically: take the absolute value of the average luminance difference between the i-th and (i-1)-th collection units and divide it by the device's maximum luminance adjustment range to obtain the luminance change component; take the absolute value of the average color temperature difference between the two and divide it by the device's maximum color temperature adjustment range to obtain the color temperature change component; when the luminance mode changes, record the mode change component as 1; when the luminance mode does not change, record the mode change component as 0; add the luminance change component, color temperature change component, and mode change component to obtain the luminance change. If the device does not support color temperature adjustment or mode adjustment, the corresponding component is recorded as 0, which does not affect the calculation of the luminance change.

[0027] If i is 1, the initial light emission parameters of the device before the start of the current sleep adjustment cycle are used as the reference light emission parameters corresponding to the (i-1)th collection unit; when there are no initial light emission parameters of the device, the earliest light emission parameters collected in the first collection unit are used as the reference light emission parameters, so that the first collection unit can still complete the calculation of the light emission change.

[0028] Similarly, the volume, playback rhythm, and sound type of the sound parameters in the i-th and (i-1)-th collection units are read, and the difference between the corresponding sound parameters is processed in the same way as the change in light emission, by taking the absolute value, normalizing the range, and adding them to obtain the change in sound emission. If there are sound parameters that do not support adjustment or switching, the corresponding change quantity is recorded as 0. If i is 1, the initial sound parameter before the start of the current sleep regulation cycle or the earliest sound parameter collected in the first collection unit is used as the reference sound parameter.

[0029] When the change in light emission is not less than the light emission change threshold, the change in sound emission is not less than the sound emission change threshold, and the usage response interval is not less than the preset continuous usage interval, it indicates that the device is undergoing a significant gradual adjustment of light and sound. Furthermore, if the user does not interrupt, turn off, or reverse the adjustment within a short period, the current collection unit is determined to be part of the sleep guidance process. A sleep guidance status item is generated, and the changes in light emission, sound emission, and usage response interval within the current collection unit are written into the sleep guidance status data. The sleep guidance status item characterizes the sleep assistance process that the user is receiving, formed by the combined reduction of light emission and sound emission.

[0030] When the change in light emission is less than the light emission change threshold and the change in sound emission is less than the sound emission change threshold, it indicates that the photoacoustic output within the current collection unit remains in a low-change state. A post-sleep stable state item is generated, and the low-perceived light emission state, low-disturbance sound emission state, and continuous no-intervention response state are written into the post-sleep stable state data. Specifically, the low-perceived light emission state indicates that the light emission brightness, color temperature, or gradual change is within a small range; the low-disturbance sound emission state indicates that the sound volume, playback rhythm, or actual playback state is within a small range; and the continuous no-intervention response state indicates that the user has not performed any operations such as increasing brightness, increasing volume, switching modes, pausing and restarting, or resuming within the current collection unit.

[0031] When the response interval is less than the preset short-time response interval, and the user data shows paused and restarted or closed and reopened, it indicates that the user may need light and sound soothing again after a short interruption. A short-time sleep-back state entry is generated, and the restart time, readjustment type, and current light and sound output status are written into the short-time sleep-back state data. Readjustment types can include restarting light emission, restarting sound emission, simultaneously activating light emission and sound emission, increasing volume, decreasing brightness, or switching soothing modes.

[0032] The response interval is determined based on the time difference between the user's operation and the most recent change in photoacoustic output. The change in photoacoustic output refers to any change in brightness, color temperature, light emission mode, sound volume, playback rhythm, or sound type. The user's operation refers to any moment when the user turns the device on, off, pauses, restarts, adjusts brightness, adjusts volume, or switches modes. For example, if the device reduces brightness and volume at 22:10:00, and the user does not turn it off or pause at 22:14:00 but continues to use it, then the response interval is 4 minutes, indicating the user's continued acceptance of this photoacoustic change.

[0033] The light emission change threshold, sound emission change threshold, preset continuous use interval, and preset short-time response interval can be pre-stored in the device control program or background data processing program. The light emission change threshold can be determined based on the device's minimum adjustable brightness step size, minimum adjustable color temperature step size, and the natural fluctuation range of light emission during historical stable use. The sound emission change threshold can be determined based on the device's minimum adjustable volume step size, minimum change step size of playback rhythm, and the natural fluctuation range of sound emission during historical stable use. The preset continuous use interval can be determined based on the time range from when the user turns on the device until it enters a stable use state. The preset short-time response interval can be determined based on the common time range after a brief pause followed by restarting the device. These thresholds can either use factory default values ​​or be updated based on usage data from multiple historical sleep adjustment cycles.

[0034] In addition to the above situations, the corresponding collection unit is marked as a pending match status item, and the corresponding light emission parameters, sound emission parameters, and user response parameters are retained. A pending match status item indicates that the sound and light changes and user response within the current collection unit are insufficient to directly determine sleep induction, post-sleep stability, or short-term fall asleep reversal; further judgment is needed in conjunction with the next collection unit. By retaining pending match status items, the status judgment result can be avoided from being directly affected by occasional operations or short-term changes within a single collection unit.

[0035] S2 includes: establishing a state matching matrix based on photoacoustic adjustment state data to establish the correspondence between photoacoustic output and user response, and generating the corresponding state when the state matching matrix meets preset state matching conditions. The state matching matrix is ​​a data correspondence table arranged by aggregation unit or user re-operation event, used to compare the light output state, sound output state, and user response state in the same data structure. The matrix rows correspond to aggregation units or re-operation events, the matrix columns correspond to the state items to be compared, and the matrix cells are filled with corresponding parameter values ​​and state markers.

[0036] Specifically, the preset state matching conditions are set based on the light emission change threshold, the sound emission change threshold, the preset continuous use interval, the preset short-time response interval, and the device's low output parameter range. The device's low output parameter range can be determined by the device's factory parameters, user configuration parameters, or the average output parameters during historical stable use periods, including low brightness range, soft color temperature range, low volume range, and smooth playback rhythm range. These conditions are used to determine whether the light emission state, sound emission state, and user response state in different collection units meet the matching requirements of the corresponding scenario.

[0037] Read the sleep guidance status data within each collection unit. This data includes changes in luminescence, changes in sound emission, and the interval between responses. Low-stimulation direction refers to changes in luminescence output towards reducing visual stimulation, specifically including one or more of the following: decreased brightness, color temperature change from high to low, decreased flicker frequency, weakened dynamic light effect, decreased sustained luminescence intensity, or gradual dimming of luminescence. Low-interference direction refers to changes in sound output towards reducing auditory interference, specifically including one or more of the following: decreased volume, slowed rhythm, reduced high-frequency components, reduced abrupt changes, reduced cue sounds, reduced sound field variation amplitude, or gradual fading of sound.

[0038] The light output of the current collection unit is compared with the light output of the previous collection unit. If the light output of the current collection unit represents a change in the direction of low stimulation and the amount of light change is not less than a preset light change threshold, the current collection unit is determined to meet the light reduction condition and is marked as a light reduction state. The sound output of the current collection unit is compared with the sound output of the previous collection unit. If the sound output of the current collection unit represents a change in the direction of low interference and the amount of sound change is not less than a preset sound change threshold, the current collection unit is determined to meet the sound reduction condition and is marked as a sound reduction state.

[0039] If, within the preset response observation time after a change in photoacoustic output, the user does not perform any interruptive operations such as turning off, pausing, increasing brightness in reverse, increasing volume in reverse, or switching to high-stimulation output, and the time interval between the moment of change in photoacoustic output and the moment of the next valid operation is not less than the preset continuous use interval, the current collection unit is determined to meet the continuous use conditions and is marked as a continuous use state.

[0040] Using the collection unit number as the matrix rows and the light reduction state, sound reduction state, and continuous use state as the matrix columns, the changes in light emission, sound emission, usage response interval, and corresponding state flags are written into the matrix units to obtain the sleep guidance matching matrix. If the light reduction condition, sound reduction condition, and continuous use condition are all met simultaneously within the same collection unit, a sleep guidance correspondence is determined to be formed between light emission guidance, sound soothing, and continuous use by the user, and a second corresponding state is generated.

[0041] Based on the post-sleep stable state data, a post-sleep stable matching matrix is ​​established in the same manner. The matrix uses the collection unit number as the matrix rows and low-perception light emission state, low-disturbance sound emission state, and weakened response state as the matrix columns. Specifically, the low-perception light emission state indicates that the light emission change is less than the light emission change threshold, and the light emission brightness is within the low output parameter range of the device; the low-disturbance sound emission state indicates that the sound emission change is less than the sound emission change threshold, and the sound volume is within the low output parameter range of the device; and the weakened response state indicates that the user has not performed any active intervention operations such as brightness increase, volume increase, mode switching, pause and restart, or re-start within consecutive collection units. The low-perception light emission state, low-disturbance sound emission state, and weakened response state are filled into the corresponding matrix units to obtain the post-sleep stable matching matrix. If all three states within the same collection unit meet the corresponding conditions, a post-sleep stable correspondence is established between the light emission output, sound emission output, and the user's weak response, and the first corresponding state is generated.

[0042] Based on short-term resuscitation data, the restart time, readjustment type, and luminous and audible parameters before and after readjustment are extracted to determine the short-term response state, luminous callback state, and audible callback state. The short-term response state indicates that the user paused and then restarted or closed and then reopened within a preset short-term response interval; the luminous callback state indicates that after the operation, the luminous output changes towards lower brightness, softer color temperature, or a gradual dimming mode; the audible callback state indicates that after the operation, the audible output changes towards lower volume, a gentler rhythm, or a soothing sound. Using the user's re-operation type as the matrix row and the luminous and audible output parameters after the re-operation as the matrix columns, the short-term response state, luminous callback state, and audible callback state are filled into the corresponding matrix cells to obtain the resuscitation matching matrix. If the short-term response state meets the corresponding condition in the same re-operation event, and at least one of the luminous or audible callback states meets the corresponding condition, then a resuscitation correspondence is established between the user's re-operation and the soothing audible and visual callback, and a third corresponding state is generated.

[0043] S3 includes: when the first corresponding state is determined, generating asynchronous coupling parameters based on the matching results between the light output, sound output and user response weakening in the sleep-stable matching matrix, so as to reduce the degree of simultaneous start-up, simultaneous change or simultaneous continuation between the light output and the sound output.

[0044] Specifically, the system reads the emission parameters, sound parameters, and user operation records corresponding to the current collection unit from the post-sleep stable matching matrix. The emission parameters include the current average brightness, current average color temperature, and current emission gradient duration; the sound parameters include the current average volume, current average playback rhythm, and current actual sound duration; and the user operation records include brightness increase, volume increase, restart, mode switch, pause and restart, and the corresponding operation time.

[0045] First, calculate the luminous emission maintenance deviation. Read the target brightness, target color temperature, and target luminous emission gradient percentage. The target brightness, target color temperature, and target luminous emission gradient percentage are used to represent the luminous output state that is expected to be maintained during the post-sleep stabilization phase. These can be determined by the device's factory post-sleep mode parameters, user-preset post-sleep parameters, or the average luminous emission parameters of historical post-sleep stabilization phases. If user-set values ​​exist, they are used first. If historical post-sleep stabilization data exists, the aggregation units that are determined to be the first corresponding state in multiple historical sleep adjustment cycles can be extracted, and the average brightness, average color temperature, and average luminous emission gradient percentage can be calculated as the current target luminous emission parameters. The brightness deviation is calculated by subtracting the target brightness from the current average brightness and taking the absolute value, then dividing by the device's maximum brightness adjustment range. The color temperature deviation is calculated by subtracting the target color temperature from the current average color temperature and taking the absolute value, then dividing by the device's maximum color temperature adjustment range. The current luminous gradient duration is divided by the total duration of the current collection unit to obtain the current luminous gradient percentage; this percentage is then subtracted from the target luminous gradient percentage and the absolute value is taken to obtain the gradient deviation. The brightness deviation, color temperature deviation, and gradient deviation are added together and divided by 3 to obtain the luminous emission maintenance deviation. If the device does not support color temperature adjustment, the color temperature deviation is recorded as 0.

[0046] Next, calculate the vocal sustaining deviation. Read the target volume, target playback rhythm, and target vocal duration percentage. The target volume, target playback rhythm, and target vocal duration percentage represent the vocal output state expected to be maintained during the post-sleep stabilization phase. These can be determined by the device's factory post-sleep mode parameters, user-preset post-sleep parameters, or the average vocal parameters from historical post-sleep stabilization phases. If historical post-sleep stabilization data exists, the aggregation units identified as the first corresponding state from multiple historical sleep regulation cycles can be extracted, and the average vocal volume, average playback rhythm, and average vocal duration percentage can be calculated as the current target vocal parameters. The volume deviation is calculated by subtracting the target volume from the current average volume and taking the absolute value, then dividing by the device's maximum volume adjustment range. The rhythm deviation is calculated by subtracting the target rhythm from the current average playback rhythm and taking the absolute value, then dividing by the device's maximum playback rhythm adjustment range. The current actual playback duration is divided by the total duration of the current collection unit to obtain the current playback duration percentage; this percentage is then subtracted from the target playback duration percentage and the absolute value is taken to obtain the playback duration deviation. The volume deviation, rhythm deviation, and playback duration deviation are summed and divided by 3 to obtain the playback maintenance deviation. When the current collection unit is silent, both the current average volume and the current playback duration percentage are recorded as 0.

[0047] Next, calculate the response weakening duration parameter. Count the number of collection units that have not experienced consecutive brightness increases, volume increases, restarts, mode switches, or pause-and-restart events up to the current collection unit, obtaining the number of consecutive inactive units. Calculate the time difference between the last user operation and the end time of the current collection unit, obtaining the inactive duration. Divide the number of consecutive inactive units by the preset number of consecutive units to obtain the first ratio. Divide the inactive duration by the preset inactive time to obtain the second ratio. Add the first and second ratios and divide by 2 to obtain the response weakening duration parameter. The preset inactive time can be determined by the device's default sleep stabilization confirmation time, or by the average time between the last user operation and the entry into the first corresponding state in historical sleep adjustment cycles. The preset number of consecutive units can be obtained by dividing the preset inactive time by the collection unit duration and rounding up.

[0048] The algorithm reads the light emission maintenance deviations of the current and previous collection units, subtracts the previous light emission maintenance deviation from the current one to obtain the change in light emission deviation. It also reads the sound emission maintenance deviations of the current and previous collection units, subtracting the previous one from the current sound emission maintenance deviation to obtain the change in sound emission deviation. The algorithm compares the positive and negative directions of the changes in light emission deviation and sound emission deviation. If both increase, both decrease, or both are within a preset stable range, a consistent direction value is determined; if their directions are opposite, a inconsistent direction value is determined. The absolute values ​​of the changes in light emission deviation and sound emission deviation are then subtracted, and the absolute value is taken to obtain the amplitude difference. This amplitude difference is divided by the preset maximum allowable amplitude difference, and then subtracted by one to obtain the approximate amplitude change value. The algorithm counts the number of collection units in the current observation window that simultaneously meet the requirements of consistent direction and approximate amplitude change, and divides this number by the total number of collection units in the observation window to obtain the synchronization duration value. Finally, the algorithm adds the consistent direction value, the approximate amplitude change value, and the synchronization duration value, and divides by three to obtain the photoacoustic deviation synchronization parameter. Finally, the photoacoustic deviation synchronization parameter is multiplied by the response weakening duration parameter to obtain the synchronization coupling degree. The greater the synchronization coupling degree, the more the light emission holding deviation and sound emission holding deviation continue to show a synchronous change relationship with consistent direction and similar amplitude even when the user operation response has weakened.

[0049] When the degree of synchronous coupling exceeds the preset low disturbance limit after sleep, asynchronous coupling parameters are generated; when the degree of synchronous coupling does not exceed the preset low disturbance limit after sleep, the current audio-visual output control parameters remain unchanged. The preset low disturbance limit after sleep can be determined by the allowed linkage strength of the device's factory sleep mode, or it can be obtained by extracting the aggregation units that are determined to be in the first corresponding state from multiple historical sleep adjustment cycles, calculating the degree of synchronous coupling corresponding to each aggregation unit, and using the average degree of synchronous coupling plus the preset margin as the preset low disturbance limit after sleep. The preset margin can be determined based on the device's control accuracy or the historical parameter fluctuation range to avoid frequent triggering of adjustments due to slight fluctuations.

[0050] Asynchronous coupling parameters include one or more of the following: light output limiting parameters, sound output holding parameters, and sound-light linkage disengagement parameters. Light output limiting parameters include upper limits on brightness, color temperature change, and light emission gradation duration; sound output holding parameters include upper limits on volume, playback rhythm, and sound duration percentage; sound-light linkage disengagement parameters include synchronous start / stop flags and synchronous change / stop flags, used to prevent light and sound output from starting and changing at the same time, or to prevent them from changing synchronously at the same rhythm. Through these parameters, the light and sound outputs during the stable sleep phase are changed from synchronous changes to low-change, low-interference, or staggered changes, thereby reducing continuous sound and light stimulation.

[0051] S4 includes: when the second or third corresponding state is determined, based on the sleep guidance response or readjustment response recorded in the sleep guidance matching matrix or re-sleep matching matrix, performing a synchronization analysis on the luminescence change process and vocal soothing process in the current sleep disorder regulation process, and generating synchronization coupling parameters when there are deviations in the initiation time, change amplitude, or duration. The synchronization coupling parameters are used to compensate for the corresponding luminescence and vocal parameters in the existing photoacoustic regulation process, so that the luminescence change process and the vocal soothing process are more matched in time and change trend.

[0052] Specifically, the light emission status item, sound emission status item, and user response status item corresponding to the current collection unit or the current re-operation event are read from the sleep guidance matching matrix or the re-sleep matching matrix. The light emission status item includes the start time of the light emission change, the end time of the light emission change, the amount of light emission change, and the duration of light emission; the sound emission status item includes the start time of the sound emission change, the end time of the sound emission change, the amount of sound emission change, and the duration of sound emission; the user response status item includes the user response time, the readjustment type, and the continuous use flag. The above times are obtained from the light emission command issuance time and the sound emission command issuance time in the device control record and the operation time in the user operation record; the light emission change amount and the sound emission change amount are calculated according to the parameter difference between adjacent collection units.

[0053] First, analyze the startup time deviation. Subtract the start time of the light emission change from the start time of the sound emission change and take the absolute value to obtain the startup time difference. The preset synchronous startup allowable time can be determined based on the device control refresh cycle, light emission response delay, sound emission response delay, and the average startup time difference during continuous user use in the historical sleep guidance phase. When the startup time difference is greater than the preset synchronous startup allowable time, it indicates that the light emission change and the sound emission change are not synchronized, and a startup compensation amount needs to be generated. If the light emission change occurs earlier than the sound emission change, the portion of the time difference exceeding the preset synchronous startup allowable time is used as the light emission delay compensation amount or as the sound emission advance compensation amount; if the sound emission change occurs earlier than the light emission change, the excess portion is used as the sound emission delay compensation amount or as the light emission advance compensation amount. This yields the synchronous startup time parameter.

[0054] Next, analyze the deviation in amplitude. Read the changes in light emission and sound emission, and normalize them according to their respective value ranges, threshold values, or preset level mapping rules to obtain normalized light emission and sound emission change values, ensuring both are within the same comparison scale. Then, subtract the normalized light emission change value from the normalized sound emission change value and take the absolute value to obtain the amplitude difference, which characterizes the closeness between the amplitude changes in light emission and sound emission output. The smaller the amplitude difference, the closer the light emission and sound emission outputs are in terms of adjustment strength; the larger the amplitude difference, the more significant the difference in adjustment strength.

[0055] Simultaneously, determine whether the directions of change in light output and sound output are consistent. Consistent changes mean that the light output changes towards reducing visual stimulation, and the sound output changes towards reducing auditory interference. Examples include a decrease in light brightness, a change in color temperature from high to low, and a change in the light emission mode from flashing or dynamic changes to gradual dimming or stable low brightness. Simultaneously, the sound volume decreases, the playback rhythm slows down, high-frequency components decrease, or the sound type switches to a soothing tone. If the light output changes towards reducing visual stimulation while the sound output changes towards increasing auditory stimulation, or vice versa, then the directions of change are considered inconsistent.

[0056] The preset allowable variation range can be determined based on the device's minimum adjustment step size, the user-set intensity of sound and light changes, or the average variation range difference of historical effective sleep guidance phases. When the variation range difference exceeds the preset allowable variation range difference, or when the directions of change are inconsistent, a compensation amount is generated. If the change in light emission is greater than the change in sound emission, the excess is used as a compensation amount to reduce light emission or increase sound emission; if the change in sound emission is greater than the change in light emission, the excess is used as a compensation amount to reduce sound emission or increase light emission; if the directions of change are inconsistent, the side that does not conform to the soothing direction is adjusted to the soothing direction, thus obtaining the sound and light change correction parameters.

[0057] Next, analyze the duration deviation. Subtract the light emission duration from the sound emission duration and take the absolute value to obtain the duration difference. The preset allowed synchronous duration can be determined based on the collection unit duration, the device's default soothing playback duration, the user-set gradient duration, or the average duration difference of historical effective guidance phases. When the duration difference is greater than the preset allowed synchronous duration, the excess is used as a duration compensation amount. If the light emission duration is shorter than the sound emission duration, the excess is used as a light emission extension compensation amount or a sound emission shortening compensation amount; if the sound emission duration is shorter than the light emission duration, the excess is used as a sound emission extension compensation amount or a light emission shortening compensation amount, increasing the overlap output time between the two and bringing the duration difference back within the preset allowed synchronous duration.

[0058] Finally, the synchronization start-up time parameter, the audio-visual change correction parameter, and the synchronization duration parameter are combined to generate the synchronization coupling parameter. This parameter does not directly adjust the audio-visual response based on the sleep state, but rather on the light output data, sound output data, and user response data already generated by the photoacoustic adjustment device. It determines whether the original sleep guidance or readjustment process has problems such as starting too early, starting too late, excessive changes, insufficient changes, inconsistent direction, or excessive or insufficient duration, and compensates for the corresponding time, change, and duration, thereby improving the matching between the photoacoustic closed-loop data processing results and the actual sleep disorder adjustment process.

[0059] The S3 and S4 processes described above are parallel processing steps tailored to different usage scenarios, not sequential execution. For example, when a user has entered a stable sleep phase and the light and sound adjustment device detects that the user has not performed any actions such as increasing brightness, volume, pausing and restarting, or switching modes for an extended period, it indicates that the user's need for device intervention has decreased. In this case, step S3 is executed. By analyzing whether the light and sound outputs still start simultaneously, change simultaneously, or continue simultaneously, asynchronous coupling parameters are generated to change the light and sound outputs from synchronous changes to low changes or staggered changes, reducing continuous light and sound stimulation during the sleep phase. Similarly, when a user is in the sleep guidance phase, or when the device is restarted shortly after being paused or turned off, it indicates that there is still a need for sleep assistance or readjustment. In this case, step S4 is executed. By analyzing the deviations in start time, change amplitude, and duration between the light change process and the sound soothing process, synchronous coupling parameters are generated to compensate for the time, change, and duration of the existing light and sound adjustment process.

[0060] like Figure 3 The schematic diagram of the external structure of the photoacoustic modulation device shown illustrates the overall shape of the device, the arrangement of the front light-emitting area, and the side sound-emitting areas. Figure 4The schematic diagram of the photoacoustic modulation device shown illustrates the location of the sound-emitting area and the structure along the thickness of the casing from a side view. Figure 5 The schematic diagram of the bottom structure of the photoacoustic adjustment device shows the arrangement of the bottom interfaces, heat dissipation, and support structure. In this diagram, number 1 represents the light-emitting area on the front of the device, number 2 represents the sound-emitting area on the side of the device, number 3 represents the power interface, charging interface, or control interface area on the bottom or back of the device, and number 4 represents the heat dissipation and ventilation area on the bottom of the device, which may include heat dissipation holes, fan vents, or ventilation grilles.

[0061] The light-emitting area can be used to output lighting content with adjustable brightness, color temperature, flashing frequency, or gradation rhythm, and generate corresponding light output data during device operation. The sound-emitting area can be used to output sound content with adjustable volume, sound type, playback rhythm, or sound field variation amplitude, and generate corresponding sound output data. The interface area can be used to connect external power supplies, charging devices, or control circuits, providing connection conditions for device operation, data transmission, or maintenance and testing. The heat dissipation and ventilation area can be used to dissipate the heat generated by the internal light-emitting units, sound-emitting units, or control circuits during operation, to ensure the stability of the device during continuous operation.

[0062] The photoacoustic adjustment device can also collect or record user operation response data during use, such as data on turning on, pausing, turning off, restarting, brightness adjustment, volume adjustment, and mode switching, and associate the operation response data with the light output data and sound output data in chronological order. It should be noted that even though the photoacoustic adjustment device is also equipped with sensors for collecting heart rate, body movement, respiration, or other physiologically related signals, this embodiment of the invention does not directly judge the user's physical condition based on these physiologically related signals. Instead, it uses the light output data, sound output data, and user operation response data as data processing objects. Through state aggregation, matrix matching, and coupling parameter compensation, it determines whether there are problems such as output asynchrony, inconsistent changes, or mismatched durations in the existing photoacoustic adjustment process, thereby improving the matching reliability between the photoacoustic closed-loop adjustment data processing results and the actual device adjustment process.

[0063] This invention provides a photoacoustic closed-loop data processing system for regulating sleep disorders, such as... Figure 2 The diagram shown illustrates the structure of a photoacoustic closed-loop data processing system for sleep disorder regulation. This system may include: The photoacoustic status collection module is used to acquire the light output data, sound output data, and user usage data generated by the photoacoustic adjustment device during the current sleep adjustment cycle. It identifies the output status of light brightness, color temperature, volume, playback rhythm, and user operations such as starting, pausing, and restarting, and collects them in time sequence according to the collection unit to form photoacoustic adjustment status data.

[0064] The state matching generation module is used to establish a state matching matrix based on the photoacoustic adjustment state data to establish the correspondence between photoacoustic output and user response. It fills the light emission state item, sound emission state item and user response state item into the corresponding matrix unit, and judges the relationship of sleep stability, sleep guidance or short-term readjustment according to the preset state matching conditions to generate the corresponding state.

[0065] The asynchronous coupling processing module is used to read the light emission parameters, sound emission parameters and user response weakening data in the sleep-stable matching matrix when the first corresponding state is determined, calculate the light emission maintenance deviation, sound emission maintenance deviation and synchronous coupling degree, and generate asynchronous coupling parameters when the synchronous linkage is too high, so as to reduce the degree of simultaneous change of light emission output and sound emission output.

[0066] The synchronous coupling processing module is used to read the light emission change time, sound emission change time, change amount and duration in the sleep guidance matching matrix or re-sleep matching matrix when the second or third corresponding state is determined, analyze the start-up, change and duration deviations, and generate synchronous coupling parameters to compensate for the time amount, change amount and duration in the existing photoacoustic adjustment process.
