背景技术Background technique

随着人民的生活水平不断提高，智能家电设备也逐渐走入用户的生活。目前，随着用户对其所在环境的热舒适度需求不断提高，空调器成为了每个家庭必不可少的智能家电设备。With the continuous improvement of people's living standards, smart home appliances have gradually entered the lives of users. At present, as users' demands for thermal comfort of their environment continue to increase, air conditioners have become an indispensable smart home appliance for every family.

现阶段，为了满足不同用户的热舒适度需求，通常在空调器中预存PMV(PredictedMean Vote，预测平均投票数)模型，以通过将环境参数及用户清醒状态下的体征参数输入至PMV模型的情况下，获取PMV模型输出的热舒适度值，从而结合PMV模型输出的热舒适度值，控制空调器执行相应的操作模式，以满足用户的热舒适度需求。但现有技术中的PMV模型是基于用户日间清醒状态下的体征参数所建立的模型，该模型并不能够准确反映用户在夜间睡眠状态下的热舒适度情况。At this stage, in order to meet the thermal comfort requirements of different users, a PMV (Predicted Mean Vote) model is usually pre-stored in the air conditioner, so as to input the environmental parameters and the physical parameters of the user's awake state into the PMV model. Then, the thermal comfort value output by the PMV model is obtained, and the air conditioner is controlled to execute the corresponding operation mode in combination with the thermal comfort value output by the PMV model to meet the user's thermal comfort requirements. However, the PMV model in the prior art is a model established based on the physical parameters of the user in the waking state during the day, and the model cannot accurately reflect the thermal comfort of the user in the sleeping state at night.

图1是本公开实施例提供的一个用于构建热舒适度模型的方法示意图；结合图1所示，本公开实施例提供一种用于构建热舒适度模型的方法，包括：1 is a schematic diagram of a method for building a thermal comfort model provided by an embodiment of the present disclosure; with reference to FIG. 1 , an embodiment of the present disclosure provides a method for building a thermal comfort model, including:

S11，空调器确定用户在睡眠状态下的人体代谢率及被服表面系数。S11, the air conditioner determines the human body metabolic rate and the clothing surface coefficient of the user in a sleeping state.

S12，空调器根据睡眠状态下的人体代谢率及被服表面系数，建立PMV模型。S12, the air conditioner establishes a PMV model according to the metabolic rate of the human body in the sleeping state and the surface coefficient of the clothing.

S13，空调器计算用于修正PMV模型的第一修正量。S13, the air conditioner calculates a first correction amount for correcting the PMV model.

S14，空调器根据PMV模型及第一修正量，构建SPMV模型。S14, the air conditioner constructs the SPMV model according to the PMV model and the first correction amount.

在本方案中，可以理解地，用户在睡眠状态下的人体代谢率与用户在清醒状态下的人体代谢率并不相同。因此，空调器可以通过获得用户进入睡眠阶段前清醒期的平均基础代谢率、用户在各睡眠阶段平均心率与进入睡眠阶段前清醒期的下降比例及用于修正代谢率模型的第二修正量进行睡眠状态下的人体代谢率的确定。此外，空调器还可以通过获得被服热阻，确定被服表面系数。这里，不同季节下的被服热阻并不相同，相应地被服散热面积也不相同。进一步地，在空调器确定用户在睡眠状态下的人体代谢率及被服表面系数后，空调器可以结合睡眠状态下的人体代谢率及被服表面系数，建立PMV模型。这里，通过结合睡眠状态下的人体代谢率及被服表面系数建立的PMV模型能够在一定程度上表征用户在夜间睡眠状态下的热舒适度情况。进一步地，为了构建更加精准地能够表征用户在夜间睡眠状态下的热舒适度情况的SPMV模型，还需要计算用于修正PMV模型的第一修正量。这里，第一修正量为温度修正量，空调器能够通过第一修正量对PMV模型因环境温度变化而引起的波动情况进行修正。这样，在空调器计算出用于修正PMV模型的第一修正量后，可以结合PMV模型及第一修正量，构建更加精准地能够表征用户在夜间睡眠状态下的热舒适度情况的SPMV模型。In this solution, it can be understood that the metabolic rate of the human body of the user in the sleeping state is different from the metabolic rate of the human body of the user in the awake state. Therefore, the air conditioner can be performed by obtaining the average basal metabolic rate of the user in the waking period before entering the sleep stage, the average heart rate of the user in each sleep stage and the decline ratio of the waking period before entering the sleep stage, and the second correction amount for correcting the metabolic rate model. Determination of the human metabolic rate during sleep. In addition, the air conditioner can also determine the surface coefficient of the clothing by obtaining the thermal resistance of the clothing. Here, the thermal resistance of the quilt in different seasons is not the same, and the heat dissipation area of the quilt is also different accordingly. Further, after the air conditioner determines the user's human body metabolic rate and the clothing surface coefficient in the sleeping state, the air conditioner can combine the human body metabolic rate and the clothing surface coefficient in the sleeping state to establish a PMV model. Here, the PMV model established by combining the metabolic rate of the human body in the sleeping state and the surface coefficient of the clothing can characterize the thermal comfort of the user in the sleeping state at night to a certain extent. Further, in order to construct a SPMV model that can more accurately represent the thermal comfort of the user in a sleep state at night, it is also necessary to calculate a first correction amount for correcting the PMV model. Here, the first correction amount is a temperature correction amount, and the air conditioner can use the first correction amount to correct the fluctuation of the PMV model caused by the change of the ambient temperature. In this way, after the air conditioner calculates the first correction amount for correcting the PMV model, the PMV model and the first correction amount can be combined to construct an SPMV model that can more accurately represent the thermal comfort of the user in the nighttime sleep state.

采用本公开实施例提供的用于构建热舒适度模型的方法，在确定用户睡眠状态下的人体代谢率及被服表面系数后，结合睡眠状态下的人体代谢率及被服表面系数建立PMV模型，并通过计算出的第一修正量对PMV模型进行修正，以得到能够反映用户在夜间睡眠状态下的热舒适度情况的SPMV模型。以此方案，解决了现有PMV模型并不能够表征用户在夜间睡眠状态下的热舒适度情况的弊端，提升了用户睡眠阶段的热舒适度判断的准确性，为用户在睡眠状态下进行空调器控制提供了准确的数据基础，满足用户热舒适度的需求。Using the method for building a thermal comfort model provided by the embodiment of the present disclosure, after determining the human body metabolic rate and the clothing surface coefficient in the user's sleep state, the PMV model is established in combination with the human body metabolic rate and the clothing surface coefficient in the sleeping state, and The PMV model is corrected by the calculated first correction amount, so as to obtain the SPMV model that can reflect the thermal comfort of the user in the sleep state at night. This solution solves the disadvantage that the existing PMV model cannot represent the thermal comfort of the user in the sleep state at night, improves the accuracy of the thermal comfort judgment of the user in the sleep stage, and provides the user with air conditioning in the sleep state. The controller control provides an accurate data base to meet the user's thermal comfort requirements.

可选地，S14，空调器根据PMV模型及第一修正量，构建SPMV模型，包括：Optionally, S14, the air conditioner constructs the SPMV model according to the PMV model and the first correction amount, including:

SPMV＝PMV+b(t)SPMV=PMV+b(t)

在本方案中，空调器可以结合PMV模型及第一修正量，构建SPMV模型。其中，b(t)为第一修正量，第一修正量为温度修正量，第一修正量用于对PMV模型因环境温度变化而引起的波动情况进行修正。SPMV模型包括：In this solution, the air conditioner can combine the PMV model and the first correction to construct the SPMV model. Among them, b(t) is the first correction amount, the first correction amount is the temperature correction amount, and the first correction amount is used to correct the fluctuation of the PMV model caused by the change of the ambient temperature. The SPMV model includes:

其中，M、I_cl、W分别表示代谢率、被服热阻以及对外机械功，且对外机械功为0。t_a、v、H、tr分别表示环境温度、风速、相对湿度以及平均辐射温度，且平均辐射温度tr与环境温度t_a数值相等。P_a、f_cl、h_c、t_cl分别表示水蒸气分压、被服表面系数、对流换热系数以及服装外表面温度。Among them, M, I_cl , and W represent metabolic rate, thermal resistance of clothing and external mechanical work, respectively, and external mechanical work is 0. t_a , v, H, and tr represent the ambient temperature, wind speed, relative humidity, and average radiation temperature, respectively, and the average radiation temperature tr is equal to the ambient temperature_ta . P_a , f_cl , h_c , and t_cl represent the partial pressure of water vapor, the surface coefficient of the clothing, the convective heat transfer coefficient and the outer surface temperature of the clothing, respectively.

采用上述SPMV模型，能够综合考虑人体参数因素、环境因素以及其他关联因素等，更加准确地构建与用户睡眠相关联的热舒适模型，与相关技术中所采用的PMV相比，可准确地反映出用户睡眠状态下实际的舒适度情况。其中，人体参数因素包括代谢率、被服热阻和对外机械功。环境因素包括环境温度、风速、相对湿度和平均辐射温度。其他关联因素包括水蒸气分压、被服表面系数、对流换热系数和服装外表面温度。The use of the above SPMV model can comprehensively consider human parameters, environmental factors and other related factors, and more accurately build a thermal comfort model related to user sleep. Compared with the PMV used in related technologies, it can accurately reflect The actual comfort level of the user in the sleep state. Among them, the parameters of human body include metabolic rate, thermal resistance of clothing and external mechanical work. Environmental factors include ambient temperature, wind speed, relative humidity, and average radiant temperature. Other relevant factors include water vapor partial pressure, clothing surface coefficient, convective heat transfer coefficient and clothing outer surface temperature.

可选地，S13，空调器计算用于修正PMV模型的第一修正量，包括：Optionally, S13, the air conditioner calculates a first correction amount for correcting the PMV model, including:

b(t)＝at-cb(t)=at-c

其中，b(t)为第一修正量，a为第一比例系数，t为室内温度，c为第一修正常数。Among them, b(t) is the first correction amount, a is the first proportional coefficient, t is the indoor temperature, and c is the first correction constant.

在本方案中，可以对多个实验数据进行拟合，以获得拟合后的第一修正量的计算公式。这里，拟合后的第一修正量的计算公式具有良好的线性相关性。作为一种示例，在拟合优度R²为0.88的情况下，第一比例系数a为0.2294，第一修正常数c为6.4026。即第一修正量的计算公式为b(t)＝0.2294t-6.4026。由此可见，第一修正量与室内温度的变化情况息息相关。以此方案，能够获得更加精准地第一修正量，为SPMV模型的构建过程提供了准确的数据基础。In this solution, a plurality of experimental data can be fitted to obtain a calculation formula of the fitted first correction amount. Here, the calculation formula of the fitted first correction amount has a good linear correlation. As an example, when the goodness of fit R² is 0.88, the first proportional coefficient a is 0.2294, and the first correction constant c is 6.4026. That is, the calculation formula of the first correction amount is b(t)=0.2294t-6.4026. It can be seen that the first correction amount is closely related to the change of the indoor temperature. With this solution, a more accurate first correction amount can be obtained, which provides an accurate data basis for the construction process of the SPMV model.

图2是本公开实施例提供的一个用于确定用户在睡眠状态下的人体代谢率的方法示意图；结合图2所示，可选地，S11，空调器确定用户在睡眠状态下的人体代谢率，包括：Fig. 2 is a schematic diagram of a method for determining a user's human body metabolic rate in a sleeping state provided by an embodiment of the present disclosure; with reference to Fig. 2, optionally, S11, the air conditioner determines the user's human body metabolic rate in a sleeping state ,include:

S21，空调器获得用户进入睡眠阶段前清醒期的平均基础代谢率、用户在各睡眠阶段平均心率与进入睡眠阶段前清醒期的下降比例及用于修正代谢率模型的第二修正量。S21 , the air conditioner obtains the average basal metabolic rate of the user in the waking period before entering the sleep stage, the average heart rate of the user in each sleep stage and the reduction ratio of the waking period before entering the sleep stage, and the second correction amount for correcting the metabolic rate model.

S22，空调器根据用户进入睡眠阶段前清醒期的平均基础代谢率、用户在各睡眠阶段平均心率与进入睡眠阶段前清醒期的下降比例及用于修正代谢率模型的第二修正量，确定睡眠状态下的人体代谢率。S22, the air conditioner determines sleep according to the average basal metabolic rate of the user in the waking period before entering the sleep stage, the average heart rate of the user in each sleep stage and the reduction ratio of the waking period before entering the sleep stage, and the second correction amount used to correct the metabolic rate model state of the body's metabolic rate.

在本实施例中，用户进入睡眠阶段前清醒期的平均基础代谢率可以为40W/m²。还可以通过多种方式获得用户在各睡眠阶段平均心率与进入睡眠阶段前清醒期的下降比例：In this embodiment, the average basal metabolic rate in the waking period before the user enters the sleep stage may be 40W/m² . The ratio of the average heart rate of the user in each sleep stage to the reduction in the waking period before entering the sleep stage can also be obtained in a number of ways:

在第一种方式中，在当前的室内温度为预设温度的情况下，空调器可以获得用户的性别信息、用户当前所处的睡眠周期信息及用户在其睡眠周期内的睡眠阶段信息；从而空调器可以根据预设的对应关系，将与用户的性别信息、用户当前所处的睡眠周期信息及用户在其所处睡眠周期内的睡眠阶段信息相对应的下降比例作为用户在各睡眠阶段平均心率与进入睡眠阶段前清醒期的下降比例。In the first method, when the current indoor temperature is the preset temperature, the air conditioner can obtain the user's gender information, the user's current sleep cycle information and the user's sleep stage information in the sleep cycle; thus The air conditioner can use the user's gender information, the user's current sleep cycle information, and the user's sleep stage information in the sleep cycle as the average of the user in each sleep stage according to the preset corresponding relationship. The ratio of heart rate to the drop in waking period before entering sleep phase.

在第二种方式中，在环境温度为26℃时，还可以针对男性用户和女性用户在各睡眠阶段与进入睡眠阶段前清醒期的下降比例进行汇总，并结合汇总后的表格数据，获得用户在各睡眠阶段平均心率与进入睡眠阶段前清醒期的下降比例，具体请参考表1与表2。这里，表1表示男性用户在环境温度为26℃时各睡眠阶段与进入睡眠阶段前清醒期的下降比例。表2表示女性用户在环境温度为26℃时各睡眠阶段与进入睡眠阶段前清醒期的下降比例。其中，W/m²为人体新陈代谢单位。In the second method, when the ambient temperature is 26°C, it is also possible to summarize the decline ratio of male users and female users in each sleep stage and the waking period before entering the sleep stage, and combine the summarized table data to obtain user The average heart rate in each sleep stage and the reduction ratio of the waking period before entering the sleep stage, please refer to Table 1 and Table 2 for details. Here, Table 1 shows the reduction ratio of each sleep stage and the awake period before entering the sleep stage when the ambient temperature of the male user is 26°C. Table 2 shows the reduction ratio of female users in each sleep stage and the waking period before entering the sleep stage when the ambient temperature is 26°C. Among them, W/m² is the metabolic unit of human body.

表1与表2中，W表示清醒期，N1表示浅睡期，N2/N3表示深睡期，R表示快速眼动期。第一睡眠周期被定义为用户入睡后的2.5小时。第二睡眠周期被定义为用户进入睡眠后除第一睡眠周期以外的其他睡眠阶段的时长。In Table 1 and Table 2, W represents the awake period, N1 represents the light sleep period, N2/N3 represents the deep sleep period, and R represents the rapid eye movement period. The first sleep cycle is defined as 2.5 hours after the user falls asleep. The second sleep cycle is defined as the duration of other sleep stages except the first sleep cycle after the user enters sleep.

由以上实验数据可知，用户在环境温度为26℃的环境中进入睡眠后，在不同的睡眠阶段，用户在各睡眠阶段平均心率与进入睡眠阶段前清醒期的下降比例f具有较大差异。由此，导致代谢率M数值也存在差异。由于影响SPMV模型输出量的因素包括有代谢率M，根据该SPMV模型所获得地用户在不同的睡眠阶段的舒适度值必然产生浮动，甚至出现超出舒适度上限阈值或者小于舒适度下限阈值的情况。与此同时，影响SPMV模型输出量的因素还包括环境温度、相对湿度、风速等。因此，在代谢率M发生变化且导致SPMV模型输出量超出预设范围时，可通过对环境温度、相对湿度和风速三种参数进行调控，以使经调控后再次获得的SPMV模型输出量位于预设范围内，从而提升用户睡眠阶段的舒适度。其中，预设范围为[舒适度下限阈值，舒适度上限阈值]。需要说明的是，舒适度下限阈值和舒适度上限阈值可根据用户需求设定。例如，舒适度下限阈值为-0.3，舒适度上限阈值为0.3。或者，舒适度下限阈值为-0.5，舒适度上限阈值为0.5。此外，在SPMV模型输出量高于舒适度上限阈值时，表明用户产生热感。且SPMV模型输出量与舒适度上限阈值的差值越大，用户的热感越强烈。在SPMV模型输出量低于舒适度下限阈值时，表明用户产生冷感。且SPMV模型输出量与舒适度下限阈值的差值的绝对值越大，用户的冷感越强烈。It can be seen from the above experimental data that after the user enters sleep in an environment with an ambient temperature of 26°C, in different sleep stages, the average heart rate of the user in each sleep stage and the reduction ratio f of the waking period before entering the sleep stage are quite different. As a result, the metabolic rate M values also differ. Since the factors affecting the output of the SPMV model include the metabolic rate M, the comfort level of the user in different sleep stages obtained according to the SPMV model will inevitably fluctuate, and even exceed the upper threshold of comfort or be smaller than the lower threshold of comfort. . At the same time, the factors that affect the output of the SPMV model also include ambient temperature, relative humidity, and wind speed. Therefore, when the metabolic rate M changes and the output of the SPMV model exceeds the preset range, the three parameters of ambient temperature, relative humidity and wind speed can be adjusted so that the output of the SPMV model obtained again after adjustment is within the preset range. within the set range, thereby improving the comfort of the user's sleep stage. Among them, the preset range is [the lower threshold of comfort, the upper threshold of comfort]. It should be noted that the lower threshold for comfort and the upper threshold for comfort may be set according to user requirements. For example, the lower threshold for comfort is -0.3 and the upper threshold for comfort is 0.3. Alternatively, the lower threshold for comfort is -0.5 and the upper threshold for comfort is 0.5. In addition, when the output of the SPMV model is higher than the upper threshold of comfort, it indicates that the user feels thermal. And the greater the difference between the output of the SPMV model and the upper threshold of comfort, the stronger the user's thermal sensation. When the output of the SPMV model is lower than the lower threshold of comfort, it indicates that the user feels cold. And the greater the absolute value of the difference between the output of the SPMV model and the lower threshold of comfort, the stronger the coldness of the user.

在第三种方式中，还可以通过以下方式确定用户在各睡眠阶段平均心率与进入睡眠阶段前清醒期的下降比例：In the third method, the ratio of the average heart rate of the user in each sleep stage to the awake period before entering the sleep stage can also be determined in the following ways:

f＝C_i·(t-26)+f(26)f=C_i ·(t-26)+f(26)

其中，f为用户在各睡眠阶段平均心率与进入睡眠阶段前清醒期的下降比例，Ci为第三比例系数，且其数值与睡眠周期相关联。在睡眠周期为第一睡眠周期时，C₁＝-0.0086。在睡眠周期为第二睡眠周期时，C₂＝-0.0203。t为室内温度，可以通过空调器关联的温度传感器检测获得，也可以通过空调器关联的终端设备采集天气信息后获得。Among them, f is the ratio of the average heart rate of the user in each sleep stage to the reduction ratio of the waking period before entering the sleep stage, and Ci is the third proportional coefficient, and its value is related to the sleep cycle. When the sleep cycle is the first sleep cycle, C₁ =-0.0086. When the sleep cycle is the second sleep cycle, C₂ =-0.0203. t is the indoor temperature, which can be detected by a temperature sensor associated with the air conditioner, or obtained by collecting weather information through a terminal device associated with the air conditioner.

以此方案，能够在空调器获得用户进入睡眠阶段前清醒期的平均基础代谢率、用户在各睡眠阶段平均心率与进入睡眠阶段前清醒期的下降比例及用于修正代谢率模型的第二修正量后，通过用户进入睡眠阶段前清醒期的平均基础代谢率、用户在各睡眠阶段平均心率与进入睡眠阶段前清醒期的下降比例及用于修正代谢率模型的第二修正量，确定更加精准地睡眠状态下的人体代谢率。With this solution, the air conditioner can obtain the average basal metabolic rate of the user in the waking period before entering the sleep stage, the average heart rate of the user in each sleep stage and the reduction ratio of the waking period before entering the sleep stage, and the second correction for correcting the metabolic rate model. After the user enters the sleep stage, the average basal metabolic rate of the waking period before the user enters the sleep stage, the average heart rate of the user in each sleep stage and the decline ratio of the waking period before entering the sleep stage, and the second correction amount used to correct the metabolic rate model, the determination is more accurate. Metabolic rate of the human body during sleep.

可选地，S22，空调器根据用户进入睡眠阶段前清醒期的平均基础代谢率、用户在各睡眠阶段平均心率与进入睡眠阶段前清醒期的下降比例及用于修正代谢率模型的第二修正量，确定睡眠状态下的人体代谢率，包括：Optionally, S22, the air conditioner is based on the average basal metabolic rate of the user in the waking period before entering the sleep stage, the average heart rate of the user in each sleep stage and the decline ratio of the waking period before entering the sleep stage, and the second correction for correcting the metabolic rate model. amount to determine the body's metabolic rate during sleep, including:

M＝M_B·[1-c(t)·f]_M =MB ·[1-c(t)·f]

其中，M为睡眠状态下的人体代谢率，M_B为用户进入睡眠阶段前清醒期的平均基础代谢率，c(t)为第二修正量，f为用户在各睡眠阶段平均心率与进入睡眠阶段前清醒期的下降比例。Among them, M is the metabolic rate of the human body in the sleep state, M_B is the average basal metabolic rate of the user in the waking period before entering the sleep stage, c(t) is the second correction amount, and f is the average heart rate of the user in each sleep stage and entering sleep. Decrease in the proportion of pre-stage wakefulness.

在本实施例中，由上述论述可知，f＝C_i·(t-26)+f(26)。因此，还可以推导出睡眠状态下的人体代谢率为：M＝M_B·{1-c(t)·[(t-26)·C_i+f(26)]}。需要说明的是，前述公式不适用于第二睡眠周期清醒期代谢率的计算以及不适用于处于极端低温或者极端高温环境下代谢率的计算。以此方案，能够通过用户进入睡眠阶段前清醒期的平均基础代谢率、用户在各睡眠阶段平均心率与进入睡眠阶段前清醒期的下降比例及用于修正代谢率模型的第二修正量，确定更加精准地睡眠状态下的人体代谢率。In this embodiment, as can be seen from the above discussion, f=C_i ·(t-26)+f(26). Therefore, the metabolic rate of the human body in the sleep state can also be deduced:_M =MB·{1-c(t)·[(t-26)·C_i +f(26)]}. It should be noted that the foregoing formula is not applicable to the calculation of the metabolic rate in the wake-up period of the second sleep cycle and is not applicable to the calculation of the metabolic rate in an environment of extreme low temperature or extreme high temperature. In this scheme, the average basal metabolic rate in the waking period before the user enters the sleep stage, the average heart rate of the user in each sleep stage and the reduction ratio of the waking period before entering the sleep stage, and the second correction amount used to correct the metabolic rate model can be determined. More accurate human metabolic rate in sleep state.

可选地，可以通过以下方式确定第二修正量：Optionally, the second correction amount can be determined in the following manner:

C(t)＝kt-zC(t)=kt-z

其中，C(t)为第二修正量，k为第二比例系数，t为室内温度，z为第二修正常数。Among them, C(t) is the second correction amount, k is the second proportional coefficient, t is the indoor temperature, and z is the second correction constant.

在本方案中，可以对多个实验数据进行拟合，以获得拟合后的第二修正量的计算公式。这里，拟合后的第二修正量的计算公式具有良好的线性相关性。作为一种示例，在拟合优度R²为0.99的情况下，第二比例系数k为0.425，第二修正常数z为9.9283。即第二修正量的计算公式为C(t)＝0.425t-9.9283。由此可见，第二修正量与室内温度的变化情况息息相关。以此方案，能够获得更加精准地第二修正量，为人体代谢率模型的构建过程提供了准确的数据基础。In this solution, a plurality of experimental data can be fitted to obtain a calculation formula of the fitted second correction amount. Here, the calculation formula of the second correction amount after fitting has a good linear correlation. As an example, when the goodness of fit R² is 0.99, the second proportional coefficient k is 0.425, and the second correction constant z is 9.9283. That is, the calculation formula of the second correction amount is C(t)=0.425t-9.9283. It can be seen that the second correction amount is closely related to the change of the indoor temperature. In this way, a more accurate second correction amount can be obtained, which provides an accurate data basis for the construction process of the human metabolic rate model.

可选地，S32，空调器根据被服热阻，确定被服表面系数，包括：Optionally, in S32, the air conditioner determines the surface coefficient of the clothing according to the thermal resistance of the clothing, including:

f_cl＝0.75(1+0.2I_cl)f_cl =0.75(1+0.2I_cl )

其中，f_cl为被服表面系数，I_cl为被服热阻。Among them, f_cl is the surface coefficient of the quilt, and I_cl is the thermal resistance of the quilt.

在本实施例中，不同季节下的被服厚度及被服覆盖面积不同，相应地被服热阻也不相同。因此，空调器可以结合已获得的被服热阻确定被服表面系数。在另外一种示例中，空调器还可以获得当前的季节信息及用户处于睡眠状态时的裸露部位；并根据当前的季节信息确定被服散热面积；从而根据用户处于睡眠状态时的裸露部位及被服散热面积，确定被服表面系数。具体地，空调可以根据预设的对应关系，将与用户处于睡眠状态时的裸露部位及被服散热面积相对应的被服表面系数，确定为被服表面系数。在另外一种示例中，被服表面系数还可以通过查表的方式确定。待查询表格中可存储有用户在不同被服下的被服表面系数。在一种优化的方案中，空调器还可以获得当前的季节信息及用户处于睡眠状态时的裸露面积；并根据当前的季节信息确定被服散热面积；从而将被服散热面积与用户处于睡眠状态时的裸露面积的比值作为被服表面系数。这样，能够通过多种方式确定更加精准地被服表面系数。In this embodiment, the thickness of the quilt and the covering area of the quilt in different seasons are different, and the thermal resistance of the quilt is also different accordingly. Therefore, the air conditioner can determine the surface coefficient of the suit in combination with the obtained thermal resistance of the suit. In another example, the air conditioner can also obtain the current season information and the exposed parts of the user when the user is sleeping; and determine the heat dissipation area of the clothing according to the current season information; so as to dissipate heat according to the exposed parts of the user and the clothing when the user is sleeping area, determine the surface coefficient of the suit. Specifically, the air conditioner may determine the clothing surface coefficient corresponding to the exposed part of the user and the heat dissipation area of the clothing as the clothing surface coefficient according to the preset corresponding relationship. In another example, the clothing surface coefficient can also be determined by looking up a table. The table to be queried can store the clothing surface coefficients of the user under different clothing. In an optimized solution, the air conditioner can also obtain the current season information and the exposed area when the user is in a sleeping state; and determine the heat dissipation area of the clothing according to the current seasonal information; so as to compare the heat dissipation area of the clothing with the exposed area when the user is in a sleeping state. The ratio of the exposed area is used as the clothing surface coefficient. In this way, more accurate clothing surface coefficients can be determined in various ways.

可选地，S12，空调器根据睡眠状态下的人体代谢率及被服表面系数，建立PMV模型，包括：Optionally, in S12, the air conditioner establishes a PMV model according to the metabolic rate of the human body in the sleeping state and the surface coefficient of the clothing, including:

Specifically, the water vapor partial pressure_Pa is determined according to the ambient temperature and relative humidity, and is calculated by the following formula:

具体地，对流换热系数根据环境温度、平均辐射温度以及风速确定，具体采用以下公式计算：Specifically, the convective heat transfer coefficient is determined according to the ambient temperature, average radiation temperature and wind speed, and is calculated by the following formula:

具体地，服装外表面温度具体采用以下公式计算：Specifically, the outer surface temperature of the garment is calculated by the following formula:

t_cl＝35.7-0.0275(M-W)-0.155I_cl[(M-W)-3.05(5.73-0.007(M-W)-P_a)-t_cl =35.7-0.0275(MW)-0.155I_cl [(MW)-3.05(5.73-0.007(MW)-P_a )-

0.42{(M-W)-58.15}-0.0173M(5.87-P_a)-0.0014M(34-t_a)]0.42{(MW)-58.15}-0.0173M(5.87-P_a )-0.0014M(34-t_a )]

以此方案，空调器能够结合睡眠状态下的人体代谢率及被服表面系数，建立PMV模型。In this way, the air conditioner can combine the metabolic rate of the human body and the surface coefficient of the clothing in the sleep state to establish a PMV model.

图4是本公开实施例提供的一个用于控制空调器的方法示意图；结合图4所示，本公开实施例提供一种用于控制空调器的方法，包括：4 is a schematic diagram of a method for controlling an air conditioner provided by an embodiment of the present disclosure; with reference to FIG. 4 , an embodiment of the present disclosure provides a method for controlling an air conditioner, including:

S41，空调器获取空调器相关联的用户在睡眠阶段的当前睡眠状态。S41, the air conditioner acquires the current sleep state of the user associated with the air conditioner in the sleep stage.

S42，空调器获得用户相关联的SPMV模型的当前舒适度值。该当前舒适度值由SPMV模型输出量确定。S42, the air conditioner obtains the current comfort level value of the SPMV model associated with the user. This current comfort level is determined by the SPMV model output.

S43，空调器在当前舒适度值与预设舒适度值不匹配的情况下，根据当前睡眠状态，执行与当前睡眠状态对应的环境控制策略，以使经调节后的当前舒适度值与预设舒适度相匹配。S43: In the case that the current comfort level value does not match the preset comfort level value, the air conditioner executes an environmental control strategy corresponding to the current sleep state according to the current sleep state, so that the adjusted current comfort level value matches the preset comfort level value. Comfort to match.

在本方案中，空调器可通过与该空调器通信连接的睡眠监测设备获取用户在睡眠阶段的当前睡眠状态。作为一种示例，睡眠监测设备为睡眠枕，睡眠枕对用户睡眠阶段的运动强度进行检测，并根据运动强度确定用户的当前睡眠状态。作为一种示例，睡眠监测设备为智能手表，且智能手表被佩戴于用户腕部。智能手表配置有陀螺仪传感器以及心率传感器，陀螺仪传感器用于检测手腕的动作幅度和频率，心率传感器用于检测用户的心率值。智能手表获取手腕的动作幅度和频率以及心率值，并进行分析处理，生成用户的当前睡眠状态。对于空调器获取用户在睡眠阶段的当前睡眠状态的方式，本公开实施例对此可不做具体限定。In this solution, the air conditioner can obtain the current sleep state of the user in the sleep stage through a sleep monitoring device that is communicatively connected to the air conditioner. As an example, the sleep monitoring device is a sleep pillow, the sleep pillow detects the exercise intensity of the user in the sleep stage, and determines the current sleep state of the user according to the exercise intensity. As an example, the sleep monitoring device is a smart watch, and the smart watch is worn on the user's wrist. The smart watch is equipped with a gyroscope sensor and a heart rate sensor. The gyroscope sensor is used to detect the movement amplitude and frequency of the wrist, and the heart rate sensor is used to detect the user's heart rate value. The smart watch obtains the movement amplitude and frequency of the wrist, as well as the heart rate value, and analyzes it to generate the current sleep state of the user. The embodiments of the present disclosure may not specifically limit the manner in which the air conditioner obtains the current sleep state of the user in the sleep stage.

进一步地，空调器按照以下方式获得用户相关联的SPMV模型的当前舒适度值：获取用户的体征参数和用户所在环境的环境参数。将体征参数和环境参数输入至SPMV模型获得SPMV模型输出量，并将该SPMV模型输出量作为用户的当前舒适度值。其中，体征参数包括代谢率、被服热阻。环境参数包括环境温度、风速和相对湿度。可以理解地，在空调器对环境温度、风速和/或相对湿度中的一个或者多个进行调节后，可将更新后的环境参数输入至SPMV模型，以实现对用户的舒适度值的更新。Further, the air conditioner obtains the current comfort level value of the SPMV model associated with the user in the following manner: obtaining physical parameters of the user and environmental parameters of the environment where the user is located. The physical parameters and environmental parameters are input into the SPMV model to obtain the output of the SPMV model, and the output of the SPMV model is taken as the current comfort level of the user. Among them, physical parameters include metabolic rate, thermal resistance of clothing. Environmental parameters include ambient temperature, wind speed and relative humidity. It can be understood that after the air conditioner adjusts one or more of the ambient temperature, wind speed and/or relative humidity, the updated ambient parameters can be input into the SPMV model to update the user's comfort level.

采用本公开实施例提供的用于控制空调器的方法，通过SPMV模型输出量可准确地获知用户的当前舒适度值，当当前舒适度值与预设舒适度值不匹配时，执行与当前睡眠状态对应的环境控制策略，以使经调控后所获得SPMV模型输出量能够与预设舒适度值相匹配，使空调器能够根据用户睡眠阶段的舒适度需求对环境进行动态调控。该方法提升了用户睡眠阶段的舒适度判断的准确性，满足用户的舒适度需求。With the method for controlling an air conditioner provided by the embodiment of the present disclosure, the current comfort level of the user can be accurately obtained through the output of the SPMV model, and when the current comfort level does not match the preset comfort level The environment control strategy corresponding to the state, so that the output of the SPMV model obtained after adjustment can match the preset comfort value, so that the air conditioner can dynamically adjust the environment according to the user's sleep stage comfort requirements. The method improves the accuracy of judging the comfort level of the user's sleep stage and meets the comfort level of the user.

可选地，S43，空调器根据当前睡眠状态，执行与当前睡眠状态对应的环境控制策略，包括：Optionally, S43, the air conditioner executes an environmental control strategy corresponding to the current sleep state according to the current sleep state, including:

空调器在当前睡眠状态表示用户入睡的情况下，获取用户的睡眠迁移状态以及当前睡眠状态相关联的睡眠期；空调器根据睡眠迁移状态以及睡眠期，调节用户相关联的环境的温湿度值和/或风速。When the current sleep state indicates that the user is asleep, the air conditioner obtains the user's sleep transition state and the sleep period associated with the current sleep state; the air conditioner adjusts the temperature and humidity values of the environment associated with the user according to the sleep transition state and the sleep period. / or wind speed.

在本实施例中，睡眠迁移状态表示用户在某睡眠期内且在相邻睡眠阶段间切换。睡眠期表示用户睡眠时所处的睡眠周期。一完整的睡眠周期由时序连续的清醒、浅睡、深睡和快速眼动构成。不同的睡眠周期内，清醒、浅睡、深睡和快速眼动的持续时长具有差异。清醒、浅睡、深睡和快速眼动表示不同的睡眠阶段。这样，该方法实时地获取用户在睡眠阶段的睡眠迁移状态以及所处的睡眠期，并根据前述睡眠迁移状态和睡眠期，对用户所在的环境的温湿度值和/或风速进行相应地调控，以使经调控后所获得的SPMV模型输出量位于预设范围内，从而满足用户睡眠阶段的舒适度需求。In this embodiment, the sleep transition state indicates that the user switches between adjacent sleep stages within a certain sleep period. The sleep period represents the sleep cycle in which the user sleeps. A complete sleep cycle consists of consecutive wakefulness, light sleep, deep sleep and rapid eye movement. The duration of wakefulness, light sleep, deep sleep, and REM varies among different sleep cycles. Awake, light sleep, deep sleep, and rapid eye movement represent different sleep stages. In this way, the method acquires the sleep transition state of the user in the sleep stage and the sleep period in real time, and adjusts the temperature and humidity value and/or wind speed of the environment where the user is located according to the aforementioned sleep transition state and sleep period. So that the output of the SPMV model obtained after regulation is within a preset range, so as to meet the comfort requirements of the user's sleep stage.

可选地，空调器在当前舒适度值大于舒适度上限阈值的情况下，根据睡眠迁移状态以及睡眠期，调节用户相关联的环境的温湿度值和/或风速，包括：Optionally, when the current comfort level is greater than the comfort level upper threshold, the air conditioner adjusts the temperature and humidity values and/or wind speed of the environment associated with the user according to the sleep transition state and the sleep period, including:

空调器在睡眠迁移状态表示睡眠切换且睡眠期表示处于第一睡眠周期的情况下，控制风机增大风速。空调器在睡眠期表示处于第二睡眠周期且睡眠迁移状态表示持续处于当前睡眠阶段的情况下，降低环境的温度值，并控制风机降低风速。The air conditioner controls the fan to increase the wind speed when the sleep transition state indicates sleep switching and the sleep period indicates the first sleep cycle. When the sleep period indicates that the air conditioner is in the second sleep cycle and the sleep transition state indicates that the air conditioner is continuously in the current sleep stage, the air conditioner reduces the temperature value of the environment, and controls the fan to reduce the wind speed.

这样，在确定睡眠切换且用户处于第一睡眠周期时，说明用户已进入睡眠阶段。经过大量实验获知，与调节环境温湿度值相比，调节风速能够使更新的SPMV模型输出量更快速地降低。因此，空调器在用户已进入睡眠阶段的情况下，控制风机增大风速，以实现对SPMV模型输出量地快速调控。在确定用户持续处于当前睡眠阶段且用户处于第二睡眠周期时，说明用户睡眠较为平稳，用户体温小幅度下降。为降低风机运行所产生的噪音对用户的睡眠产生干扰，空调器控制风机降低风速。与此同时，为保持SPMV模型输出量位于预设范围内，空调器对环境温度进行调控。In this way, when the sleep switching is determined and the user is in the first sleep cycle, it means that the user has entered the sleep stage. After a large number of experiments, it is known that adjusting the wind speed can reduce the output of the updated SPMV model more quickly than adjusting the ambient temperature and humidity values. Therefore, when the user has entered the sleep stage, the air conditioner controls the fan to increase the wind speed, so as to realize the rapid regulation of the output of the SPMV model. When it is determined that the user is continuously in the current sleep stage and the user is in the second sleep cycle, it means that the user's sleep is relatively stable, and the user's body temperature drops slightly. In order to reduce the noise generated by the fan operation and interfere with the user's sleep, the air conditioner controls the fan to reduce the wind speed. At the same time, in order to keep the output of the SPMV model within the preset range, the air conditioner controls the ambient temperature.

可选地，控制风机增大风速，包括：控制风机由初始风速以第一预设变化率升高。控制风机降低风速，包括：控制风机以第二预设变化率降低风速，直至降至初始风速；其中，第一预设变化率大于或者等于0.3米/秒且小于或者等于0.5米/秒。第二预设变化率大于或者等于0.3米/秒且小于或者等于0.5米/秒。Optionally, controlling the fan to increase the wind speed includes: controlling the fan to increase from the initial wind speed at a first preset rate of change. Controlling the fan to reduce the wind speed includes: controlling the fan to reduce the wind speed at a second preset rate of change until it falls to the initial wind speed; wherein the first preset rate of change is greater than or equal to 0.3 m/s and less than or equal to 0.5 m/s. The second preset rate of change is greater than or equal to 0.3 m/sec and less than or equal to 0.5 m/sec.

这样，风机在运行过程中会产生噪声，特别在风机以较高风速运行的场景中。为减低风机运行噪声对用户睡眠的影响，空调器可设置风机风速的预设风速范围。同时，在控制风机升高风速和降低风速过程中，若升速或降速过快，则影响用户的睡眠。因此，可设置第一预设变化率，使风速缓慢升速或者降速。前述预设风速范围为[0.1,1.2]米/秒。In this way, the fan will generate noise during operation, especially in the scenario where the fan runs at a high wind speed. In order to reduce the influence of the noise of the fan operation on the user's sleep, the air conditioner can set the preset wind speed range of the fan speed. Meanwhile, in the process of controlling the fan to increase the wind speed and decrease the wind speed, if the speed is increased or decreased too fast, the sleep of the user will be affected. Therefore, the first preset rate of change can be set to slowly increase or decrease the wind speed. The aforementioned preset wind speed range is [0.1, 1.2] m/s.

可选地，空调器在当前舒适度值小于舒适度下限阈值的情况下，根据睡眠迁移状态以及睡眠期，调节用户相关联的环境的温湿度值和/或风速，包括：Optionally, when the current comfort level is less than the lower threshold of comfort level, the air conditioner adjusts the temperature and humidity value and/or wind speed of the environment associated with the user according to the sleep transition state and the sleep period, including:

空调器在睡眠迁移状态表示睡眠切换且睡眠期表示处于第一睡眠周期的情况下，控制风机降低风速，并保持环境的温湿度值。空调器在睡眠期表示处于第二睡眠周期且睡眠迁移状态表示持续处于当前睡眠阶段的情况下，控制风机升高风速。When the sleep transition state indicates sleep switching and the sleep period indicates that the air conditioner is in the first sleep cycle, the air conditioner controls the fan to reduce the wind speed and maintain the temperature and humidity value of the environment. The air conditioner controls the fan to increase the wind speed when the sleep period indicates that the air conditioner is in the second sleep cycle and the sleep transition state indicates that the air conditioner is continuously in the current sleep stage.

这样，在当前舒适度值小于舒适度下限阈值时，说明SPMV模型输出量偏低。空调器在确定用户睡眠切换且处于第二睡眠周期时，可通过降低风速来进行输出量的调控。与此同时，空调器保持环境的温湿度值不变。在确定用户处于第二睡眠周期且用户持续处于当前睡眠阶段时，为使SPMV模型输出量由舒适度下限阈值降至预设范围内，空调器控制风机升高风速。In this way, when the current comfort value is less than the lower threshold of comfort, it means that the output of the SPMV model is low. When the air conditioner determines that the user is in a sleep switch and is in the second sleep cycle, the air conditioner can adjust the output by reducing the wind speed. At the same time, the air conditioner keeps the temperature and humidity of the environment unchanged. When it is determined that the user is in the second sleep cycle and the user continues to be in the current sleep stage, in order to reduce the output of the SPMV model from the lower comfort level threshold to a preset range, the air conditioner controls the fan to increase the wind speed.

可选地，在当前舒适度值小于舒适度下限阈值的情况下，空调器根据睡眠迁移状态以及睡眠期，调节用户相关联的环境的温湿度值和/或风速，包括：Optionally, when the current comfort level is less than the lower threshold of comfort level, the air conditioner adjusts the temperature and humidity value and/or wind speed of the environment associated with the user according to the sleep transition state and the sleep period, including:

空调器在睡眠迁移状态表示睡眠切换且睡眠期表示处于第一睡眠周期的情况下，控制风机降低风速，并保持环境的温湿度值。空调器在睡眠期表示处于第二睡眠周期且睡眠迁移状态表示持续处于当前睡眠阶段的情况下，控制风机升高风速。空调器重新获取新的当前舒适度值。空调器在新的当前舒适度值大于舒适度上限阈值的情况下，控制环境的温度以第一预设温度变化量降低。空调器在新的当前舒适度值小于舒适度下限阈值的情况下，控制环境的温度以第二预设温度变化量升高，并控制环境的相对湿度至预设相对湿度范围内。其中，预设相对湿度范围为[50％RH,65％RH]。When the sleep transition state indicates sleep switching and the sleep period indicates that the air conditioner is in the first sleep cycle, the air conditioner controls the fan to reduce the wind speed and maintain the temperature and humidity value of the environment. The air conditioner controls the fan to increase the wind speed when the sleep period indicates that the air conditioner is in the second sleep cycle and the sleep transition state indicates that the air conditioner is continuously in the current sleep stage. The air conditioner regains the new current comfort level. When the new current comfort level value of the air conditioner is greater than the comfort level upper threshold value, the temperature of the control environment is decreased by the first preset temperature change amount. The air conditioner controls the temperature of the environment to increase by the second preset temperature change amount when the new current comfort level value is less than the lower limit threshold value of the comfort level, and controls the relative humidity of the environment to be within a preset relative humidity range. The preset relative humidity range is [50%RH, 65%RH].

这样，经实验获知，在风速和相对湿度保持不变的情况下，SPMV模型输出量的变化量与温度的变化量呈正相关。具体地，温度升高1℃，SPMV模型输出量升高幅度约为0.5～0.6。温度下降1℃，SPMV模型输出量下降幅度约为0.5～0.6。基于以上实验数据，空调器在当前舒适度值大于舒适度上限阈值时，控制环境的温度以第一预设温度变化量降低，以使SPMV模型输出量小幅度下降。在当前舒适度值小于舒适度下限阈值时，控制环境的温度以第二预设温度变化量升高，并控制环境的相对湿度至预设相对湿度范围内，既调控SPMV模型输出量，又使调控后的相对湿度满足用户的舒适度需求。In this way, it is known through experiments that the variation of the output of the SPMV model is positively correlated with the variation of the temperature when the wind speed and relative humidity remain unchanged. Specifically, when the temperature increases by 1°C, the output of the SPMV model increases by about 0.5 to 0.6. When the temperature drops by 1°C, the output of the SPMV model decreases by about 0.5 to 0.6. Based on the above experimental data, when the current comfort level of the air conditioner is greater than the comfort level upper threshold, the temperature of the control environment is decreased by the first preset temperature change, so that the output of the SPMV model decreases slightly. When the current comfort value is less than the lower threshold of comfort, the temperature of the control environment is increased by the second preset temperature change, and the relative humidity of the environment is controlled to be within the preset relative humidity range, which not only regulates the output of the SPMV model, but also makes The regulated relative humidity meets the user's comfort requirements.

可选地，本公开实施例还提供一种用于控制空调器的方法，包括：Optionally, an embodiment of the present disclosure further provides a method for controlling an air conditioner, including:

空调器获取空调器相关联的用户在睡眠阶段的当前睡眠状态；空调器获得用户相关联的SPMV模型的当前舒适度值；空调器在当前舒适度值与预设舒适度值不匹配的情况下，获得用户相关联的环境参数的优先级，环境参数包括风速、相对湿度以及温度，以根据环境参数的优先级，对用户相关联的环境进行调控。The air conditioner obtains the current sleep state of the user associated with the air conditioner in the sleep stage; the air conditioner obtains the current comfort level value of the SPMV model associated with the user; the air conditioner obtains the current comfort level value that does not match the preset comfort level value , to obtain the priority of the environmental parameters associated with the user. The environmental parameters include wind speed, relative humidity, and temperature, so as to control the environment associated with the user according to the priority of the environmental parameters.

在本实施例中，因影响SPMV模型的输出量的因素较多，为兼顾空调器的调控效率以及能耗，空调器可预设环境参数的优先级。作为一种示例，优先级由高到低为风速、相对湿度、温度。作为另一种示例，优先级由高到低为风速、温度、相对湿度。可以理解地，由于调整风速对SPMV模型的输出量的变化量要高于调整温湿度对SPMV模型的输出量的变化量，并且环境温温度和相对湿度的升降需要时间，因此，将风速确定为最高优先级；空调器根据当前睡眠状态，执行与当前睡眠状态对应的环境控制策略，以使经调节后的当前舒适度值与预设舒适度相匹配。In this embodiment, since there are many factors affecting the output of the SPMV model, in order to take into account the regulation efficiency and energy consumption of the air conditioner, the air conditioner can preset the priority of the environmental parameters. As an example, the priorities from high to low are wind speed, relative humidity, and temperature. As another example, the priorities from high to low are wind speed, temperature, and relative humidity. Understandably, since the change of the output of the SPMV model by adjusting the wind speed is higher than the change of the output of the SPMV model by adjusting the temperature and humidity, and the rise and fall of the ambient temperature and relative humidity takes time, therefore, the wind speed is determined as The highest priority; the air conditioner executes an environmental control strategy corresponding to the current sleep state according to the current sleep state, so that the adjusted current comfort level matches the preset comfort level.

采用本公开实施例提供的用于控制空调器的方法，既有效地提升用户睡眠阶段的舒适度判断的准确性，又提高空调器的环境调控效率。并且降低能耗。可以理解地，风速、温度、相对湿度三种类型的环境参数。空调器在实际调控过程中，若仅调控其中一项环境参数，无法使SPMV模型的输出量落入预设舒适度范围内，可调控其他两项环境参数或者调控其他两项中任一项环境参数，以调控SPMV模型的输出量。具体地，风速偏大将影响用户睡眠，因此，设置预设风速范围为0.1m/s～1.2m/s。相对湿度过高或者过低会造成用户不适，设置预设相对湿度范围为40％～70％。Using the method for controlling an air conditioner provided by the embodiments of the present disclosure not only effectively improves the accuracy of judging the comfort level of the user in the sleep stage, but also improves the environmental regulation efficiency of the air conditioner. and reduce energy consumption. Understandably, there are three types of environmental parameters: wind speed, temperature, and relative humidity. In the actual control process of the air conditioner, if only one of the environmental parameters is regulated, the output of the SPMV model cannot fall within the preset comfort level range, and the other two environmental parameters can be regulated or any one of the other two environmental parameters can be regulated. parameters to regulate the output of the SPMV model. Specifically, if the wind speed is too high, the user's sleep will be affected. Therefore, the preset wind speed range is set to be 0.1m/s to 1.2m/s. If the relative humidity is too high or too low, it will cause discomfort to the user. The preset relative humidity range is 40% to 70%.

在实际应用中，空调器与睡眠枕通信连接，睡眠枕实时向空调器传输用户的当前睡眠状态。风机的初始风速为0.1m/s。第一预设变化率为0.3m/s。舒适度下限阈值以及舒适度上限阈值分别为-0.3，0.3。用于控制空调器的方法具体如下：In practical applications, the air conditioner is connected to the sleep pillow in communication, and the sleep pillow transmits the user's current sleep state to the air conditioner in real time. The initial wind speed of the fan is 0.1m/s. The first preset rate of change is 0.3m/s. The lower threshold of comfort and the upper threshold of comfort are -0.3 and 0.3, respectively. The method used to control the air conditioner is as follows:

空调器获取当前的环境参数并输入至SPMV模型，SPMV模型输出量为0.4。由此，确定当前舒适度值大于舒适度上限阈值。空调器接收睡眠枕发送的睡眠信号，该睡眠信号携带有睡眠迁移状态和用户当前的睡眠期。睡眠迁移状态为执行睡眠切换且当前的睡眠期为第一睡眠周期。空调器在初始风速基础上，以第一预设变化率提高风速值0.4m/s并以该风速持续运行5分钟。并且，空调器保持环境温湿度不变。空调器再次接收睡眠枕发送的新的睡眠信号，新的睡眠迁移状态为未迁移，新的睡眠期为第二睡眠周期。由于SPMV模型输出量的变化量与环境温度的变化量呈正相关，因此，空调器降低环境的温度值ΔT，并控制风机降低风速至初始风速。空调器重新获取SPMV模型输出量为0.18。由此，确定当前环境参数满足用户的舒适度需求。The air conditioner obtains the current environmental parameters and inputs them into the SPMV model, and the output of the SPMV model is 0.4. Thus, it is determined that the current comfort level value is greater than the comfort level upper threshold. The air conditioner receives the sleep signal sent by the sleep pillow, where the sleep signal carries the sleep transition state and the current sleep period of the user. The sleep transition state is to perform sleep switching and the current sleep period is the first sleep cycle. On the basis of the initial wind speed, the air conditioner increases the wind speed value by 0.4 m/s at the first preset rate of change and continues to run at this wind speed for 5 minutes. Moreover, the air conditioner keeps the ambient temperature and humidity unchanged. The air conditioner receives the new sleep signal sent by the sleep pillow again, the new sleep transition state is not transitioned, and the new sleep period is the second sleep cycle. Since the change in the output of the SPMV model is positively correlated with the change in the ambient temperature, the air conditioner reduces the ambient temperature value ΔT and controls the fan to reduce the wind speed to the initial wind speed. The air conditioner regains the SPMV model output as 0.18. Thereby, it is determined that the current environmental parameters meet the comfort requirements of the user.
