噪音是影响人体睡眠的最主要因素之一，如果噪音太大，特别是嘈杂的噪音或者不规则噪音，最容易导致人体失眠或者无法深度入睡，最终导致人体精神匮乏、无力。Noise is one of the most important factors affecting human sleep. If the noise is too loud, especially loud noises or irregular noises, it is most likely to cause insomnia or inability to fall asleep deeply, and ultimately lead to lack of spirit and powerlessness.
现有的空调器带有睡眠模式，以期能够在用户睡眠时降低空调的运行噪音。但是，目前的睡眠模式只是机械地对室内风机的转速和室外压缩机的运行频率进行调节，例如进入睡眠模式后将室内风机的转速降至最低、压缩机的频率控制在较低的范围，这种控制方式并没有考虑到用户的舒适度需求，导致环境舒适度降低，影响了用户体验。The existing air conditioner has a sleep mode, in order to reduce the operating noise of the air conditioner when the user is sleeping. However, the current sleep mode only mechanically adjusts the rotational speed of the indoor fan and the operating frequency of the outdoor compressor. This control method does not take into account the user's comfort needs, resulting in reduced environmental comfort and affecting user experience.
相应地，本领域需要一种新的睡眠模式的控制方法来解决上述问题。Accordingly, there is a need in the art for a new sleep mode control method to solve the above problems.

如图1所示，为了解决现有空调器运行睡眠模式时环境舒适度降低的问题，本申请提供了一种睡眠模式的控制方法，应用于空调器，其中空调器包括室内换热器、室外换热器、压缩机、膨胀阀、室内风机、室外风机等，其具体连接方式和工作原理属于本领域公知常识，在此不再赘述。As shown in FIG. 1 , in order to solve the problem of reduced environmental comfort when the existing air conditioner operates in the sleep mode, the present application provides a sleep mode control method, which is applied to the air conditioner, wherein the air conditioner includes an indoor heat exchanger, an outdoor The specific connection methods and working principles of heat exchangers, compressors, expansion valves, indoor fans, outdoor fans, etc. belong to common knowledge in the art, and will not be repeated here.
其中，睡眠模式的控制方法主要包括如下步骤：The control method of the sleep mode mainly includes the following steps:
S101、当空调器进入睡眠模式时，获取压缩机的实际运行频率和室内风机的实际转速；例如，空调遥控器上设置有睡眠模式的按钮，用户通过按下按钮来启动睡眠模式，或者用户也可以通过与服务器或空调通讯的用户端来实现睡眠模式的打开，其中，用户端可以为移动终端 上安装的APP，移动终端包括但不限于手机、平板电脑等。另外，压缩机的实际运行频率和室内风机的实际转速的获取方式本领域较为常见，本申请对此不作限制，任何能够获取到压缩机的实际运行频率和室内风机的实际转速的方式均可以应用于本申请。S101. When the air conditioner enters the sleep mode, obtain the actual operating frequency of the compressor and the actual rotational speed of the indoor fan; for example, a button for sleep mode is set on the remote control of the air conditioner, and the user presses the button to start the sleep mode, or the user also The sleep mode can be turned on through a client communicating with the server or the air conditioner, wherein the client can be an APP installed on a mobile terminal, and the mobile terminal includes but is not limited to a mobile phone, a tablet computer, and the like. In addition, the method of obtaining the actual operating frequency of the compressor and the actual rotational speed of the indoor fan is relatively common in the field, and this application does not limit this, and any method that can obtain the actual operating frequency of the compressor and the actual rotational speed of the indoor fan can be applied in this application.
S103、获取每个睡眠阶段的目标频率和目标转速；本申请中，睡眠阶段优选地分为三个，分别为第一阶段、第二阶段和第三阶段，其中第一阶段为入睡阶段，第二阶段为深度睡眠阶段，第三阶段为睡醒前阶段。研究表明，人体刚入睡时，对外界的刺激敏感度最低，随着睡眠进程，刺激敏感度逐渐提高，睡眠周期结束前对外界的刺激敏感度最高。当然，睡眠阶段分为三个仅仅为本申请中较为优选的方式，在其他实施方式中，本领域技术人员还可以对睡眠阶段的划分进行调整，将睡眠阶段分为更少或更多的阶段。S103.

The second stage is the deep sleep stage, and the third stage is the pre-sleep stage. Studies have shown that when the human body first falls asleep, the sensitivity to external stimuli is the lowest, with the progress of sleep, the sensitivity to stimuli gradually increases, and the sensitivity to external stimuli is the highest before the end of the sleep cycle. Of course, dividing the sleep stages into three is only a preferred way in this application. In other embodiments, those skilled in the art can also adjust the division of sleep stages, and divide the sleep stages into fewer or more stages. .
本申请中，目标频率和目标转速分别指每个睡眠阶段结束时压缩机和室内风机需要达到的运行参数，也即，压缩机分别在第一阶段、第二阶段和第三阶段结束时需要达到的运行频率，以及室内风机在第一阶段、第二阶段和第三阶段结束时需要达到的转速。本申请中，将上述三个阶段的目标频率分别记为第一目标频率、第二目标频率以及第三目标频率，将上述三个阶段您的目标转速分别记为第一目标转速、第二目标转速和第三目标转速。较为优选地，每个睡眠阶段的目标频率和目标转速根据人体舒适度试验预先确定，也就是说，该目标频率和目标转速在确定时是以人体睡眠时的舒适程度为前提的，下文将对几种可能的试验方式进行介绍。本申请中，压缩机在每个睡眠阶段的目标频率以及室内风机在每个运行阶段的目标转速可以预先存储于空调器内的，如存储于空调器的存储器内，当控制方法执行时，只需从存储器内调取该目标频率和目标转速即可。In this application, the target frequency and the target rotational speed respectively refer to the operating parameters that the compressor and the indoor fan need to reach at the end of each sleep stage, that is, the compressor needs to reach at the end of the first stage, the second stage and the third stage respectively. , and the speed that the indoor fan needs to reach at the end of the first, second and third stages. In this application, the target frequencies of the above three stages are respectively recorded as the first target frequency, the second target frequency and the third target frequency, and your target rotational speed in the above three stages are recorded as the first target rotational speed and the second target frequency respectively. rotational speed and the third target rotational speed.

When the control method is executed, only The target frequency and target rotational speed need to be retrieved from the memory.
S105、基于实际运行频率和每个睡眠阶段的目标频率，确定压缩机在每个睡眠阶段的变频速度；例如，在获取到压缩机的实际运行频率和每个睡眠阶段的目标频率后，基于实际运行频率与第一目标频率计算压缩机在第一阶段的第一变频速度，基于第一目标频率与第二目标频率计算压缩机在第二阶段的第二变频速度，基于第二目标频率与第三目标频率计算压缩机在第三阶段的第三变频速度。S105. Determine the frequency conversion speed of the compressor in each sleep stage based on the actual operating frequency and the target frequency of each sleep stage; for example, after obtaining the actual operating frequency of the compressor and the target frequency of each sleep stage, based on the actual The operating frequency and the first target frequency are used to calculate the first inverter speed of the compressor in the first stage, and the second inverter speed of the compressor in the second stage is calculated based on the first target frequency and the second target frequency. The three target frequencies calculate the third inverter speed of the compressor in the third stage.
其中，在一种可替换的实施方式中，由于第一目标频率、第二目标频率与第三目标频率均为预设的值，因此也可以将基于第一目标频率与第二目标频率计算出来的第二变频速度和基于第二目标频率与第三目标频率计算出来的第三变频速度预先存储于空调器内，方便控制方法运行时直接调用。Wherein, in an alternative embodiment, since the first target frequency, the second target frequency and the third target frequency are all preset values, it is also possible to calculate the value based on the first target frequency and the second target frequency The second frequency conversion speed and the third frequency conversion speed calculated based on the second target frequency and the third target frequency are stored in the air conditioner in advance, which is convenient for direct calling when the control method is running.

Determine the acceleration of the indoor fan in each sleep stage based on the actual speed and the target speed of each sleep stage; for example, after obtaining the actual speed of the indoor fan and the target speed of each sleep stage, based on the actual speed and the first speed A target speed calculates the first acceleration of the indoor fan in the first stage, calculates the second acceleration of the indoor fan in the second stage based on the first target speed and the second target speed, and calculates the indoor fan based on the second target speed and the third target speed. The third acceleration in the third stage.
其中，在一种可替换的实施方式中，由于第一目标转速、第二目标转速与第三目标转速均为预设的值，因此也可以将基于第一目标转速与第二目标转速计算出来的第二加速度和基于第二目标转速与第三目标转速计算出来的第三加速度预先存储于空调器内，方便控制方法运行时直接调用。Wherein, in an alternative embodiment, since the first target rotational speed, the second target rotational speed and the third target rotational speed are all preset values, the calculation based on the first target rotational speed and the second target rotational speed may also be The second acceleration and the third acceleration calculated based on the second target rotational speed and the third target rotational speed are stored in the air conditioner in advance, which is convenient for direct calling when the control method is running.
S109、根据每个睡眠阶段的变频速度和加速度，控制压缩机和室内风机运行；例如，在确定出每个睡眠阶段的变频速度和加速度后，控制压缩机按照每个睡眠阶段的变频速度和加速度分阶段运行。S109, control the operation of the compressor and the indoor fan according to the frequency conversion speed and acceleration of each sleep stage; for example, after determining the frequency conversion speed and acceleration of each sleep stage, control the compressor according to the frequency conversion speed and acceleration of each sleep stage Run in stages.
通常，空调器产生的噪音分为压缩机噪音、室外风机噪音，室内风机噪音等，由于空调器运行时，门窗一般为关闭状态，室外风扇噪音几乎传递不到室内侧，因此对睡眠影响的噪音主要为室内风机的噪音和压缩机的噪音。本申请通过基于每个睡眠阶段的目标频率和目标转速确定每个睡眠阶段中压缩机的变频速度和室内风机的加速度，能够有针对性地控制压缩机和室内风机的运行噪音，并且兼顾用户舒适度的需求，在睡眠模式运行时，既保证运行噪音处于适宜的区间，又保证空调的冷热效果。Usually, the noise generated by the air conditioner is divided into compressor noise, outdoor fan noise, indoor fan noise, etc. When the air conditioner is running, the doors and windows are generally closed, and the outdoor fan noise is hardly transmitted to the indoor side, so the noise that affects sleep Mainly for indoor fan noise and compressor noise. By determining the frequency conversion speed of the compressor and the acceleration of the indoor fan in each sleep stage based on the target frequency and target rotation speed of each sleep stage, the present application can control the operating noise of the compressor and the indoor fan in a targeted manner, and take into account the comfort of the user. When running in sleep mode, it not only ensures that the operating noise is in a suitable range, but also ensures the cooling and heating effect of the air conditioner.

During the test, the bionic dummy was placed on the bed by wearing pajamas and quilts, so as to restore the clothing state of the human body during sleep to the greatest extent.
试验开始后，按照上述设定的三个睡眠阶段，控制仿生假人在每个睡眠阶段的热状态；其中，控制仿生假人在每个睡眠阶段的热状态可以通过PID调节的方式进行，如上述公开号为CN107024497A的发明专利申请中采用公式t sk＝36.4-0.054Q对仿生假人进行热状态控制，而本申请可以对上述公式进行调整，通过人体在睡眠阶段的特性(如体温降低、身体散热减少等)分别确定出每个睡眠阶段的仿生假人热状态控制公式，来模拟人体在不同睡眠阶段的热状态。当然，本领域技术人员也可以基于现有的睡眠环境的舒适性方程解算得到新的适用于睡眠阶段的热状态控制公式，然后基于热状态控制公式对仿生假人进行热状态进行控制。 After the start of the test, according to the three sleep stages set above, the thermal state of the bionic dummy in each sleep stage is controlled; wherein, the thermal state of the bionic dummy in each sleep stage can be controlled by means of PID adjustment, such as In the invention patent application with the publication number CN107024497A, the formula t sk =36.4-0.054Q is used to control the thermal state of the bionic dummy, and the present application can adjust the above formula, through the characteristics of the human body in the sleep stage (such as body temperature reduction, The thermal state control formula of the bionic dummy in each sleep stage is determined separately to simulate the thermal state of the human body in different sleep stages. Of course, those skilled in the art can also obtain a new thermal state control formula suitable for the sleep stage based on the existing comfort equation of the sleeping environment, and then control the thermal state of the bionic dummy based on the thermal state control formula.
接下来，在针对同一睡眠阶段的每次试验中，调节室内环境参数，如调节室内空调器的设定温度、室内风机的风速、室外风机的风 速、压缩机的频率等，使得室内环境的噪音满足一定的预设条件，如噪音小于40dB等。空调器按照调节好的参数运行稳定后，采集当前室内环境参数下仿生假人在当前睡眠阶段的测试数据，包括仿生假人的每个分区本体的表面温度值和表面热流值等，然后基于测试数据计算当前室内环境的舒适度评分，具体数据采集过程和评分过程本申请不在赘述，可参照上述公开号为CN107024497A的发明专利申请。Next, in each experiment for the same sleep stage, adjust the indoor environment parameters, such as adjusting the set temperature of the room air conditioner, the wind speed of the indoor fan, the wind speed of the outdoor fan, the frequency of the compressor, etc., so that the noise of the indoor environment is adjusted. Meet certain preset conditions, such as noise less than 40dB and so on. After the air conditioner runs stably according to the adjusted parameters, the test data of the bionic dummy in the current sleep stage under the current indoor environmental parameters are collected, including the surface temperature value and surface heat flow value of each partition body of the bionic dummy, and then based on the test data The data is used to calculate the comfort score of the current indoor environment. The specific data collection process and scoring process will not be repeated in this application, and reference may be made to the above-mentioned invention patent application with publication number CN107024497A.
以下表1为例，下表1示出了一组试验数据，在调节好运行参数后，开始测量仿生假人的表面温度值和表面热流值等数据，然后依据换算关系计算出当前室内环境下的全身等效空间温度，进一步基于全身等效空间温度计算得出当前室内环境下的评分。由表1可知，试验刚开始时，仿生假人的全身等效空间温度较低，随着试验的进行，其全身等效空间温度开始升高，相应的评分值也逐渐升高。当室内环境稳定时，仿生假人的全身等效空间温度和相应的评分稳定在一定的区间内。由此，可以基于稳定阶段的试验数据计算出本次试验的评分。Table 1 below is an example. Table 1 shows a set of test data. After adjusting the operating parameters, start to measure the surface temperature value and surface heat flow value of the bionic dummy, and then calculate the current indoor environment according to the conversion relationship. The whole body equivalent space temperature is further calculated based on the whole body equivalent space temperature to obtain the score under the current indoor environment. It can be seen from Table 1 that at the beginning of the test, the whole body equivalent space temperature of the bionic dummy was low, and as the test progressed, the whole body equivalent space temperature began to increase, and the corresponding score value gradually increased. When the indoor environment is stable, the whole body equivalent space temperature and the corresponding score of the bionic dummy are stable within a certain interval. Thereby, the score of this test can be calculated based on the test data in the stable phase.
本领域技术人员能够理解的是，尽管表1中给出了一定的试验数据，但是这些数据仅仅是示例性的，本申请在应用于不同型号的空调时，其试验数据和基于试验确定的目标频率和目标转速有可能不同。Those skilled in the art can understand that although certain test data are given in Table 1, these data are only exemplary. When the application is applied to different types of air conditioners, the test data and the target determined based on the test The frequency and target speed may be different.

最后，基于评分，确定每个睡眠阶段中压缩机的目标频率和风机的目标转速。在针对每个睡眠阶段进行多次试验后，可以基于试验评分结果，选择每个睡眠阶段中评分最高的一组或几组测试数据，选择该一组或几组测试数据中噪音控制效果较佳的数据对应的空调参数中压缩机的频率和室内风机的转速作为每个睡眠阶段的目标频率和目标转速。当然，也可以基于测试数据首先确定出每个睡眠阶段需要的换热量，然后依据换热量来计算或试验出满足该换热量的压缩机的运行频率和室内风机的转速作为每个睡眠阶段的目标频率和目标转速。Finally, based on the scores, the target frequency of the compressor and the target speed of the fan in each sleep stage are determined. After performing multiple tests for each sleep stage, one or several sets of test data with the highest scores in each sleep stage can be selected based on the test score results, and the noise control effect is better in this one or several sets of test data. The frequency of the compressor and the rotational speed of the indoor fan in the air-conditioning parameters corresponding to the data are taken as the target frequency and target rotational speed of each sleep stage. Of course, it is also possible to first determine the heat exchange required for each sleep stage based on the test data, and then calculate or test the operating frequency of the compressor and the rotational speed of the indoor fan that satisfy the heat exchange based on the heat exchange as each sleep stage. The target frequency and target rotational speed of the stage.
由于仿生假人的测试数据更加符合真实人体热状态，能够真实反映实际人体的冷热感，因此基于仿生假人的环境舒适度评分试验来确定压缩机的目标频率和室内风机的目标转速也更加贴合用户的实际使用情况，使得睡眠模式的控制方法准确、合理可靠。Since the test data of the bionic dummy is more in line with the thermal state of the real human body and can truly reflect the heat and cold sensation of the actual human body, it is also easier to determine the target frequency of the compressor and the target speed of the indoor fan based on the environmental comfort score test of the bionic dummy. According to the actual usage of the user, the control method of the sleep mode is accurate, reasonable and reliable.
下面对其他可能的实施方式中通过人体舒适度试验确定目标频率和目标转的过程进行简要介绍。The following briefly introduces the process of determining the target frequency and target rotation through the human comfort test in other possible implementation manners.
在其他可能的实施方式中，试验人员还可以采用平均热感觉指数(Predicted Mean Vote PMV)和预计不满意者百分数(Predicted Percentage of Dissatisfied PPD)来评价睡眠阶段的舒适度。影响热舒适性的主要因素有空气温度、空气相对湿度、平均辐射温度、相对空气流速、人体活动的代谢率与服装基础热阻等。试验人员可以按照国家标准GB/T 18049-2017的方法，通过采集试验对象(如仿生假人或试验用户)和实验环境的参数来计算PMV指数以反映当前环境的舒适度，然后基于计算结果，选取PMV指数为零或接近零的试验数据为基础确定压缩机在每个睡眠阶段的目标频率以及室内风机在每个睡眠阶段的目标转速。In other possible embodiments, the test personnel can also use the average thermal sensation index (Predicted Mean Vote PMV) and the predicted percentage of dissatisfied persons (Predicted Percentage of Dissatisfied PPD) to evaluate the comfort of the sleep stage. The main factors affecting thermal comfort are air temperature, air relative humidity, average radiant temperature, relative air velocity, metabolic rate of human activity and basic thermal resistance of clothing. The test personnel can calculate the PMV index to reflect the comfort of the current environment by collecting the parameters of the test object (such as bionic dummy or test user) and the experimental environment according to the method of the national standard GB/T 18049-2017, and then based on the calculation results, The target frequency of the compressor in each sleep stage and the target speed of the indoor fan in each sleep stage were determined based on the experimental data with a PMV index of zero or close to zero.
下面参照图2和图3，分别结合空调器的制冷模式和制热模式对本申请的睡眠模式的控制方法进行介绍。其中，图2为本申请的睡眠模式的控制方法在制冷模式下的控制过程曲线图；图3为本申请的睡眠模式的控制方法在制热模式下的控制过程曲线图。2 and 3 , the control method of the sleep mode of the present application will be introduced in combination with the cooling mode and the heating mode of the air conditioner, respectively. 2 is a control process curve diagram of the sleep mode control method of the present application in a cooling mode; FIG. 3 is a control process curve diagram of the sleep mode control method of the present application in a heating mode.

When the air conditioner operates in the cooling mode, it is determined based on experiments that the target frequency and the target rotational speed have the following relationship: the first target frequency (ie, the frequency corresponding to time t c1 in FIG. 2 ) is equal to the second target frequency (ie, time t c2 in FIG. 2 ) Corresponding frequency), the third target frequency (that is, the frequency corresponding to time t c3 in Figure 2) is smaller than the second target frequency; The rotational speed corresponding to time t c1 in FIG. 2 ), the third target rotational speed (ie, the rotational speed corresponding to time t c3 in FIG. 2 ) is greater than the second target rotational speed.
在上述关系下，假设当前空调器进入睡眠模式时的压缩机频率为f 0(即图2中t 0时刻对应的频率)，室内风机转速为r 0(即图2中t 0时刻对应的转速)，此时依据如下公式确定每个睡眠阶段的变频速度和加速度： Under the above relationship, it is assumed that the compressor frequency when the current air conditioner enters the sleep mode is f 0 (that is, the frequency corresponding to time t 0 in FIG. 2 ), and the rotational speed of the indoor fan is r 0 (that is, the rotational speed corresponding to time t 0 in FIG. 2 ) ), at this time, the frequency conversion speed and acceleration of each sleep stage are determined according to the following formula:
v c1＝(f c1-f c0)/[(t c1-t c0)×3600]    (1) v c1 =(f c1 -f c0 )/[(t c1 -t c0 )×3600] (1)
v c2＝(f c2-f c1)/[(t c2-t c1)×3600]＝0    (2) v c2 =(f c2 -f c1 )/[(t c2 -t c1 )×3600]=0 (2)
v c3＝n×(f c3-f c2)/[(t c3-t c2)×3600]      (3) v c3 =n×(f c3 -f c2 )/[(t c3 -t c2 )×3600] (3)
a c1＝(r c1-r c0)/[(t c1-t c0)×3600]＝0     (4) a c1 =(r c1 -r c0 )/[(t c1 -t c0 )×3600]=0 (4)
a c2＝(r c2-r c1)/[(t c2-t c1)×3600]     (5) a c2 =(r c2 -r c1 )/[(t c2 -t c1 )×3600] (5)
a c3＝(r c3-r c2)/[(t c3-t c2)×3600]      (6) a c3 =(r c3 -r c2 )/[(t c3 -t c2 )×3600] (6)
上述公式(1)-(6)中，v c1为第一变频速度，v c2为第二变频速度，v c3为第三变频速度；f c1为第一目标频率，f c2为第二目标频率，f c3为第三目标频率；a c1为第一加速度，a c2为第二加速度，a c3为第三加速度；n为系数，且n＞1，本申请中，n的取值范围可以为6-12。 In the above formulas (1)-(6), v c1 is the first frequency conversion speed, v c2 is the second frequency conversion speed, and v c3 is the third frequency conversion speed; f c1 is the first target frequency, and f c2 is the second target frequency , f c3 is the third target frequency; a c1 is the first acceleration, a c2 is the second acceleration, and a c3 is the third acceleration; n is a coefficient, and n>1, in this application, the value range of n can be 6-12.

v h2＝(f h2-f h1)/[(t h2-t h1)×3600]     (8) v h2 =(f h2 -f h1 )/[(t h2 -t h1 )×3600] (8)
v h3＝(f h3-f h2)/[(t h3-t h2)×3600]     (9) v h3 =(f h3 -f h2 )/[(t h3 -t h2 )×3600] (9)
a h1＝(r h1-r h0)/[(t h1-t h0)×3600]＝0     (10) a h1 =(r h1 -r h0 )/[(t h1 -t h0 )×3600]=0 (10)
a h2＝(r h2-r h1)/[(t h2-t h1)×3600]     (11) a h2 =(r h2 -r h1 )/[(t h2 -t h1 )×3600] (11)
a h3＝(r h3-r h2)/[(t h3-t h2)×3600]      (12) a h3 =(r h3 -r h2 )/[(t h3 -t h2 )×3600] (12)
