The sleep environment adjustment system of this embodiment may generally include: at least one environment adjustment device 200 and an environment adjustment controller 100.

The environmental adjustment device 200 may include various devices installed in a sleeping environment (such as a bedroom) for adjusting one or more environmental states, including but not limited to household appliances used for adjusting the environment (such as air conditioners, humidifiers, fans, Fresh air devices, aromatherapy devices, audio-visual players, scene lights, purifiers, heaters, etc.), bedding equipment (smart cushions, smart quilts, smart beds, smart chairs, etc.), and other devices that can be controlled and adjusted (such as smart curtains) , Smart window), etc. In this embodiment, the environmental parameters that can be adjusted include temperature and humidity. In addition, they can optionally include wind speed, wind direction, air quality (particulate matter, carbon dioxide, ozone, formaldehyde, etc.), smell, volume, light, etc. . The solution of this embodiment can be used to optimize the sleep environment in multiple dimensions of temperature, humidity, cleanliness, oxygen, wind, tranquility, and taste.

The environmental adjustment controller 100 is in data connection with the environmental adjustment device 200, and it can arrange network side devices such as servers and clouds, obtain various data of the sleep environment through the network, and realize the adjustment of the sleep environment by remotely sending instructions to the environmental adjustment device 200. The environmental adjustment controller 100 may also be various types of centralized control devices, which are arranged in a sleep environment and control the environmental adjustment device 200. The data connection mode between the environmental adjustment controller 100 and the environmental adjustment device 200 includes, but is not limited to, wireless transmission, infrared transmission, ultrasonic transmission, and the like. In some embodiments, the environmental adjustment controller 100 can also be used as a part of the environmental adjustment device 200, is set in the environmental adjustment device 200, and is data-connected with the own controller of the environmental adjustment device 200. For example, the environmental adjustment device 200 has a dedicated internal setting. The environmental regulation controller 100 works in cooperation with a controller dedicated to performing component control.

Fig. 2 is a schematic block diagram of an environmental adjustment controller 100 according to an embodiment of the present invention. The environmental adjustment controller 100 may generally include a memory 120 and a processor 110, wherein the memory 120 stores a control program 121 for controlling When the program 121 is executed by the processor 110, it is used to implement the intelligent adjustment method of the sleep environment of this embodiment.

Fig. 3 is a schematic diagram of a method for intelligently adjusting a sleep environment according to an embodiment of the present invention. The method for intelligently adjusting a sleep environment may include:

Step S302: Obtain a sleep trend curve of the target user, where the sleep trend curve specifies the time point and duration of each sleep stage. The sleep stages of the sleep trend curve are divided according to the user's sleep biorhythm.

Step S304: Acquire the initial target parameter of the sleep environment. The initial target parameter is preset according to the environmental information of the sleeping environment and/or the habit data of the target user. For example, the initial target parameter can be set according to the surrounding environment of the sleeping environment and other information. For example, the initial target temperature can be set to a temperature suitable for sleeping according to the local climate, season, and user preferences of the sleeping environment. In a specific example, In northern China, the initial target temperature can be set to 22 to 27 degrees Celsius in summer and 17 to 24 degrees Celsius in winter. The initial target humidity can be set to a relative humidity of 40-60%. The initial target particle concentration (taking PM2.5 as an example) can be set below 35μg/m ³ . The initial target carbon dioxide CO ₂ concentration can be set below 600 ppm. The initial target speaker effect can be a hypnotic sound of 30 decibels to 40 decibels.

The above-mentioned initial target parameters can also be modified according to the user's habit data. For example, for users who prefer coolness, the initial target temperature can be appropriately lowered; for users who are sensitive to sound, the initial target speaker effect can be reduced or turned off.

In step S306, the stage target parameters of each sleep stage are set according to the initial target parameters. Since the physiological state of the user and the sensitivity to the surrounding environment are different in each sleep stage of the sleep trend curve, this step sets the stage target parameters of each sleep stage according to the initial target parameters to meet the comfort requirements of different sleep stages.

In step S308, after the sleep mode is turned on, the environmental adjustment device 200 in the sleep environment is controlled to operate according to the stage target parameters of each sleep stage. So that the target user always gets a comfortable sleep experience all the time.

The intelligent adjustment method of the sleep environment of this embodiment uses the initial target parameters to set corresponding stage target parameters for each stage in the target user’s sleep trend curve, and after the sleep mode is turned on, the environmental adjustment device 200 in the sleep environment is controlled according to each stage. The stage target parameters of the sleep stage are operated, so that various environmental parameters change correspondingly with the user's sleep trend, and meet the comfort requirements of the user during the sleep process.

Temperature is one of the main factors affecting comfort. The specific setting method of step S306 is introduced by taking setting the stage target temperature of each sleep stage as an example. The sleep thermal comfort curve can be used as a basis for temperature setting corresponding to the sleep trend curve.

The above-mentioned sleep trend curve can be obtained through experimental research results of human sleep metabolic rate and human thermal comfort. The calculation formula of the average human skin temperature T _SK _{is: T SK} =35.7-(MW), where M is the metabolic rate and W is the external work done by the human body. Since the human body basically stops doing external work during sleep, it can be considered that W tends to zero.

Indoor temperature has the most significant impact on the human body's thermal sensation, directly affecting the heat exchange between the human body and the environment, and is also the most important variable in air conditioning control. Related studies have pointed out that the influence of air temperature on thermal sensation accounts for 50% to 60% of all factors. It follows that _{_{T a = c * T SK -d}} , wherein T _a is a suitable sleep room temperature, c and d are predetermined adjustment factor.

Further analysis can be obtained by the _{above: T a = c * (35.7} -M) -d. In addition, after studying human sleep, the early metabolic rate M showed a downward trend, and the later metabolic rate M showed an upward trend. _{Fig. 4 is a} graph showing the correspondence relationship between sleep duration t, human metabolic rate M, indoor temperature Ta suitable for sleep, and average human skin temperature T _SK. In this figure a length of 8 sleep hours, 5 hours prior decreased metabolic rate M, the average human skin temperature T _SK and appropriate sleep room temperature T _a corresponding increase. 5 M childhood metabolic rate is rising, the average human skin temperature and the indoor temperature T _SK appropriate sleep T _a reduced accordingly.

According to the experimental research results of human thermal comfort, taking into account age, gender, and fatness, representative subjects were selected to participate in the sleep thermal comfort curve test. Figure 5 shows an example test result of a sleep thermal comfort curve test. In the figure, the abscissa is the sleep time in hours; the ordinate is the air temperature in degrees Celsius. The test environment is 30 adult males as experimenters. The indoor temperature is monitored in real time by a platinum resistance-inspector temperature measuring system. The experiment environment is equipped with at least four air temperature measuring points. The air temperature in each steady-state environment is obtained from the average value of each measuring point.

From the change curve of the experimental test results in Figure 5, it can be seen that the indoor temperature rises significantly during the first 2 hours of sleep; the temperature rises slowly between 2 hours and 5 hours during sleep; the indoor temperature starts to drop after 5 hours.

Figure 6 shows the change trend of the set temperature Ts with the sleep time. The abscissa in the figure is the sleep time in hours; the ordinate is the set temperature in degrees Celsius. In order to adapt to the change of indoor air temperature in Fig. 5, the change trend of air conditioner set temperature Ts with sleep time is shown in Fig. 6, the initial target temperature is T, after 1 hour of sleep, air conditioner set temperature Ts is adjusted to T+a After 2 hours of sleep, the air conditioning set temperature Ts is adjusted to T+2a, and after 5 hours of sleep, the air conditioning set temperature Ts is adjusted to T+a. That is to say, it meets the comfort requirement that the set temperature first rises and then falls. Among them, a is the set adjustment value, which can be adjusted according to user preferences and seasons. That is, the sleep stage includes 4 stages, and the stage target temperatures of the 4 stages are respectively set as: T, T+a, T+2a, and T+a. The above-mentioned sleep trend curve, sleep stage, and stage target temperature are only examples, and those skilled in the art can make response adjustments according to specific user needs to meet the comfort requirements of different users.

Taking the above-mentioned sleep thermal comfort curve test as an example, similar experiments can be performed on different user groups (users with different physiological characteristics), so as to obtain the sleep thermal comfort curve of different users and the corresponding set temperature with the sleep stage. Variety. When adjusting the sleep environment, the corresponding sleep thermal comfort curve can be determined according to the physiological information of the target user.

In some embodiments, artificial intelligence can be used to determine the sleep trend curve. The specific implementation process can be as follows: perform sleep detection experiments on different user groups in advance to obtain batches of physiological information and corresponding sleep detection data, and combine these data Trained as a sample to get a sleep trend model. When acquiring the sleep trend curve of the target user, the physiological information of the target user can be collected; the set sleep trend model is used to classify the physiological information, and the sleep trend curve of the target user is determined. Since the training method of the artificial intelligence classification model, the data labeling method, and the specific procedures and algorithms for data processing using the classification model are all known to those skilled in the art, they will not be described in detail in this embodiment.

After determining the sleep trend curve, the initial setting temperature of the initial target parameter, and the stage setting temperature in the stage target parameter, various other parameters can be further integrated, including humidity, wind speed, wind direction, air quality, smell, volume, light, etc. . In some embodiments, it may be preferable to comprehensively optimize the seven aspects of temperature, humidity, cleanness, oxygen, wind, calmness, and taste.

Fig. 7 shows a trend curve of stage target parameters including multi-dimensional sleep environment parameters. In this schematic trend curve, at time t-1, the environmental regulation device 200 starts operation, enters the sleep mode at time t, and ends at time t+8. The whole sleep process includes the first stage (t, t+1), the second stage (t+1, t+2), the third stage (t+2, t+5), the fourth stage (t+5, t +7), the fifth stage (t+7, t+8), a total of 5 stages.

The stage before time t is the operation stage of the environmental regulation device 200 in the non-sleep mode. The environmental adjustment device 200 may operate according to a user's setting or according to other automatic operation modes.

The sleep mode is turned on at time t, and the sleep mode ends at time t+8. The following are the target temperature (unit: °C), humidity (unit: %), wind speed (that is, wind speed gear), wind direction (that is, wind deflector position), air quality (including air particles (unit: μg/m ³⁾ ), CO ₂ concentration (unit is ppm), smell (that is, aroma module status), volume (unit is dB), light (that is, scene light status) stage target parameters are introduced separately.

For the target temperature, the initial target temperature of the target temperature is T. After the sleep mode starts (at time t), the first stage target temperature is set to T; after 1 hour after sleep (at time t+1), the second stage target temperature Adjust to T+a; after 2 hours of sleep (at t+2 time), the target temperature in the third stage is adjusted to T+2a; after 5 hours after sleep (at t+5), the target temperature in the fourth stage and the fifth stage The target temperature is adjusted to T+a respectively. So as to meet the comfort requirement that the set temperature first rises and then falls.

For the target humidity, the target humidity at each stage can always be maintained within a set comfortable range during sleep, for example, between 40% and 60%. In the dry areas of northern winter, the target humidity can also be appropriately increased in the fifth stage.

For the wind speed gear, after the sleep mode is activated (at time t), the target wind speed gear in the first stage can be appropriately lowered in order to reach the set temperature requirements as soon as possible. In the subsequent stages, the wind speed can be set to breeze to avoid wind sensation. .

Regarding the wind direction, during sleep, the target wind direction at each stage can be kept to avoid blowing people, or the natural breeze can be simulated in the first stage.

For noise, during sleep, the target noise at each stage can always be maintained below the set noise threshold, for example, below 30dB. Users who are particularly sensitive to sounds can further lower the noise threshold in the first stage.

For air particulate matter, the target air particulate matter concentration at each stage can always be maintained below the set concentration threshold during sleep, for example, 35 μg/m ³ or less.

For the CO ₂ content, during sleep may be the first four stages of the CO ₂ content in the content has remained below the set threshold value, for example 600ppm or less, in order to ensure that the last paragraph of sleep to get up to improve the freshness of the user, may be the fifth stage CO _{2 The} content threshold is lowered, for example, 500 ppm.

For aromatherapy, in the first stage and the fifth stage, you can start to release concentration and refreshing scents, such as lavender and lemon scents.

For lighting, you can try to maintain a non-light environment during sleep, and gradually increase the light intensity at t+8.

It should be noted that the above content is only exemplified for the sleep trend curve and stage target parameters of a specific user, and those skilled in the art can flexibly adjust and set specific setting values on the basis of this embodiment.

The above target parameters may require a certain environmental adjustment device 200 or multiple environmental adjustment devices 200 to cooperate to achieve, for example, temperature adjustment may involve air conditioners, heaters and other equipment; humidity adjustment may involve air conditioners, humidifiers, dehumidifiers, etc.; wind power And wind direction adjustment may involve air conditioners, fans, etc.; air particulate matter and CO ₂ content may involve new fans, purifiers, etc.; light may involve automatic curtains, lights, etc.

In some embodiments, the aforementioned environmental adjustment device 200 may be integrated into an air conditioner, which may have functions such as humidification and fresh air. Thus, an air conditioner can be used to meet the overall comfort adjustment of the sleeping environment.

In the process of controlling the environmental adjustment device 200 in the sleep environment to operate according to the stage target parameters of each sleep stage, the detection data corresponding to the target parameters of each stage in the sleep environment can be obtained; according to the deviation of the target parameter of each stage from the corresponding detection data The operating state of the environmental adjustment device 200 is adjusted to reduce the deviation. That is, through feedback control, the deviation between actual data and the set target is reduced, so that the entire environment meets the comfort requirements of the target.

In particular, there may be conflicts in parameter adjustment among the above-mentioned target parameters. For example, during the operation of the environmental adjustment device 200, noise may increase accordingly. For example, when adjusting the set temperature, the air conditioner may increase the noise due to the compressor startup, or the fan may increase the noise when the purification or fresh air is turned on. The noise is also an important factor affecting the sleeping environment. Therefore, the method for intelligently adjusting the sleep environment of this embodiment also sets a limit condition for the environment adjusting device 200 with respect to noise.

The preset noise threshold can be obtained after the sleep mode is turned on. In the process of adjusting the operating state of the environmental adjustment device 200 according to the deviation between the target parameter of each stage and the corresponding detection data, the device noise generated by the operation of the environmental adjustment device 200 can also be obtained. If the device noise is greater than the noise threshold, some functions of the environmental adjustment device 200 are restricted and/or turned off to reduce the device noise. The aforementioned noise threshold may be set according to the physiological information of the user, or may be a preset value. For example, for the elderly who sleep lightly and those who are sensitive to neurasthenia, the noise threshold can be set to a lower value.

To restrict and/or close some functions of the environmental regulation device 200, it is necessary to select the restricted and/or closed functions. A process of restricting and/or shutting down part of the functions of the environmental adjustment device 200 may include: evaluating the impact of deviations between the target parameters of each stage and the corresponding detection data on sleep comfort; according to the results of the evaluation, restricting has less impact on sleep comfort If the device noise is still greater than the noise threshold after limiting the function corresponding to the deviation that has a small impact on sleep comfort, the function corresponding to the deviation that has a small impact on sleep comfort is turned off. For example, in the middle of sleep, a large temperature deviation has a greater impact on sleep comfort than a rise in air particles. The wind speed of the purification fan can be reduced, and the noise can be reduced by partially abandoning the purification function. If the wind speed is not enough to ensure that the noise is below the noise threshold, the purification function can be temporarily turned off until the temperature difference is reduced due to the temperature adjustment function, and then the purification function can be turned on again.

The evaluation of the impact on comfort can include: inputting various deviations into the preset comfort model, which is obtained by using batch environmental data and user feedback information as sample training; by sorting the comfort influencing factors output by the comfort model, Obtain the influence of various deviations on comfort. For example, through a comfort degree experiment, the comfort data of various environmental parameters in the sleep scene for the user can be collected as training samples, and then these training sample data can be trained using a machine learning algorithm to obtain a comfort model. The comfort model can be used to evaluate the impact of various environmental detection data deviations on user comfort.

Another process for restricting and/or shutting down part of the functions of the environmental adjustment device 200 may include: restoring the environmental adjustment device 200 to the operating state before the device noise is greater than the noise threshold, so as to restrict and/or shut down parts of the environmental adjustment device 200 The purpose of the function; and after the set time of restoring the operating state, re-execute the step of adjusting the operating state of the environmental regulation device 200 according to the deviation between the target parameter of each stage and the corresponding detection data. That is, after changing the parameters of a certain target stage of the environmental adjustment device 200, if the noise is found to be greater than the noise threshold, the environmental adjustment device 200 is restored to the state before the adjustment, and readjusted after a period of time. For example, the current state of temperature regulation needs to increase the frequency of the compressor of the air conditioner. After the frequency of the compressor is increased, if the equipment noise is greater than the noise threshold, the frequency of the compressor can be restored to the previous state, and the temperature adjustment speed can be limited to ensure that the noise does not exceed the standard.

The third process of restricting and/or shutting down part of the functions of the environmental adjustment device 200 may include: determining the amount of noise caused by the various functions of the environmental adjustment device 200; restricting one or more functions that cause the greatest noise; After the most noisy function or functions, if the device noise is still greater than the noise threshold, turn off the most noisy function or functions. For example, if it is found that the noise of the compressor is the main factor leading to the increase in the noise of the sleeping environment, you can first choose to limit the frequency of the compressor.

The above three ways of controlling noise can be selected according to specific adjustment requirements. Different control methods can be selected in different sleep stages. By restricting noise, the user's comfort can be further improved.

The intelligent adjustment method of the sleep environment of this embodiment uses the initial target parameters to set corresponding stage target parameters for each stage in the target user’s sleep trend curve, and after the sleep mode is turned on, the environmental adjustment device 200 in the sleep environment is controlled according to each stage. The stage target parameters of the sleep stage are operated, so that various environmental parameters change correspondingly with the user's sleep trend, and meet the comfort requirements of the user during the sleep process. In addition, this method is not limited to traditional temperature and humidity adjustments, and can also comprehensively consider various environmental considerations to achieve multi-dimensional environmental adjustments.
