附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：

图4是根据本发明一个实施例的环境调节系统的控制方法在睡眠场景中应用的示意图。
具体实施方式
图1是根据本发明一个实施例的环境调节系统的示意性架构图。本实施例的睡眠环境调节系统一般性地可包括：至少一台环境调节设备200、环境调节控制器100。
环境调节设备200可以包括各类安装于目标环境用于调节一项或多项环 境状态的设备。上述目标环境包括但不限于家居环境、办公环境、商务环境等各类室内或室外环境。环境调节设备200可以包括但不限于用于调节环境的家用电器(例如空调器、加湿器、风扇、新风装置、香薰装置、影音播放器、净化器、加热器等)，坐卧设备(智能垫、智能被、智能床、智能椅等)，影音设备(智能音箱、智能电视、智能播放器等)以及其他可以受控调节的设备(例如智能窗帘、智能窗、智能灯)等。
在本实施例中，可供调节的环境参数包括：温度以及湿度，此外还可以进一步选择性地包括：风速、风向、空气质量(颗粒物、二氧化碳、臭氧、甲醛等)、气味、音量、光线等。本实施例的方案可以用于在温、湿、净、氧、风、静、味多维度实现环境舒适度的优化。
环境调节控制器100与环境调节设备200数据连接，其可以布置服务器、云端等网络侧设备，通过网络获取检测设备检测的目标环境的各项数据，并通过向环境调节设备200远程发送指令实现环境调节。
环境调节控制器100也可以为集控设备，布置在目标环境或者目标环境周围中，并对环境调节设备200进行控制。环境调节控制器100与环境调节设备200的数据连接方式包括但不限于无线传输、红外传输、超声传输等。
在一些实施例中，环境调节控制器100还可以作为环境调节设备200的一部分，设置于环境调节设备200内，与环境调节设备200的自身控制器数据连接，例如环境调节设备200在内部设置专用的环境调节控制器100，与专用于执行部件控制的控制器配合工作。
图2是根据本发明一个实施例的环境调节控制器100的示意框图，环境调节控制器100可以包括一般性地可以包括：存储器120以及处理器110，其中存储器120内存储有控制程序121，控制程序121被处理器110执行时用于实现本实施例的环境调节系统的控制方法。处理器110可以是一个中央处理单元(central processing unit，简称CPU)，或者为数字处理单元(Digital Signal Processing，DSP)等等。处理器110通过通信接口收发数据。存储器120用于存储处理器110执行的程序。存储器120是能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何介质，也可以是多个存储器的组合。上述控制程序121可以从计算机可读存储介质下载到相应计算/处理设备或者经由网络(例如因特网、局域网、广域网和/或无线网络)下载并安装到环境调节控制器100。
图3是根据本发明一个实施例的环境调节系统的控制方法的示意图，该环境调节系统的控制方法可以包括：
步骤S302，获取目标环境内布置的环境调节设备200的运行状态。环境调节设备200的运行状态可以包括环境调节设备200各部件的启动状态、功率、运行模式等等。例如对于空调器，运行状态可以包括压缩机的频率、四通阀的流向、风机的转速、导风机构的位置等。
步骤S304，在运行状态出现变化后，检测目标环境中设备噪音。检测噪音的设备可以设置在环境调节设备200内部，也可以是设置在目标环境中的噪音检测器。由于环境调节设备200的运行状态维持不变的过程中，噪音变动较小。因此本实施例可以在环境调节设备200的运行状态改变后，对设备噪音进行检测。
检测设备噪音的过程中，可以对声音信号进行处理，排除其他声音的影响。例如将用户说话的声音、音乐的声音进行滤除。具体地，可以预先确定设备噪音的声音信号特征，在获取到周围声音信号后，提取具有设备噪音的声音信号特征的声音信号，并根据提取出的声音信号确定设备噪音的大小。
步骤S306，获取预设的噪音阈值。该噪音阈值可以预先设定的参数，在一些实施例中，噪音阈值可以根据具体的环境场景进行设置。例如控制场景中还预先配置有噪音阈值随时间变化的限制曲线。也就说，控制场景可以规定不同时间阶段的噪音阈值。例如对于睡眠场景，入睡阶段的噪音阈值可以设置为极低。在后续的睡眠阶段，噪音阈值可以设置为较低。噪音阈值可以从上述限制曲线中查询得出。
上述噪音阈值还可以根据用户的生理信息进行设置。例如对于睡眠较轻的老人以及神经衰弱的敏感者，噪音阈值可以设置为更低的数值。
步骤S308，在设备噪音大于噪音阈值的情况下，限制和/或关闭环境调节设备200的部分功能，以将设备噪音限制在噪音阈值以下。
本实施例的环境调节系统的控制方法，在目标环境内布置的环境调节设备200出现运行状态变化时，对环境调节设备200发出的设备噪音进行检测和判断，如果出现设备噪音大于噪音阈值的情况，限制和/或关闭环境调节设备200的部分功能，以将设备噪音限制在噪音阈值以下，从而有效避免噪音给用户带来的不舒适感。
本实施例的环境调节系统的控制方法，尤其适用于环境场景控制。在环 境调节系统按照场景进行控制的情况下，在步骤S302之前还可以获取场景触发指令，并确定与场景触发指令对应的控制场景，控制场景中预先配置有多条控制曲线，每条控制曲线规定有一项目标环境参数随时间变化的对应关系；控制环境调节设备200按照控制场景运行。上述控制曲线即为目标环境参数随时间变化的对应关系，可以用于配置不同的时间阶段的目标参数。
上述控制场景包括以下任意一种或多种：睡眠场景、读书场景、运动场景、会议场景、办公场景、就餐场景。控制场景根据用户的需求，将用户在不同场景下的舒适度要求进行配置。例如对于睡眠场景，可以预先配置各睡眠阶段的目标温度、目标温度、目标风速、目标风向、环境空气质量、环境气味、环境光线等目标参数。在确定进入睡眠场景后，环境调节设备200按照各睡眠阶段的目标参数运行。
控制环境调节设备200按照控制场景运行的流程可以为：获取目标环境的环境检测数据；根据各项目标环境参数与对应的环境检测数据的偏差控制环境调节设备，以减小偏差。也即通过反馈控制使环境维持于设定舒适目标范围内。
控制场景中还可以预先配置有噪音阈值随时间变化的限制曲线，该限制曲线用于规定当前控制场景下各阶段的噪音阈值。
限制和/或关闭环境调节设备200的部分功能，需要对限制和/或关闭的功能进行选择，以满足在限值噪音的同事，尽量保证环境的舒适感。
第一种限制和/或关闭环境调节设备200的部分功能的流程可以包括：评估各项目标环境参数与对应的环境检测数据的偏差对舒适度影响；限制环境调节设备200的对舒适度影响较小的偏差对应的功能；若在限制与对舒适度影响较小的偏差对应的功能之后，设备噪音仍大于噪音阈值，则关闭与对舒适度影响较小的偏差对应的功能。例如对某些场景，温度偏差较大对睡眠舒适度影响比空气颗粒物上升对舒适度影响要大，可以降低净化风机的风速，通过部分放弃净化功能来保证噪音下降，如果降低净化风机的风速不足以保证噪音低于噪音阈值，则可以暂时关闭净化功能，直至因调温功能使温差减少后，重新开启净化功能。
评估各项目标环境参数与对应的环境检测数据的偏差对舒适度影响的步骤可以包括：将各项偏差输入预设的舒适度模型，舒适度模型采用批量的环境数据与用户反馈信息作为样本训练得到；通过对舒适度模型输出的舒适 度影响因子排序，得到各项偏差对舒适度影响。
例如可以通过舒适度实验，采集不同控制场景下各种环境参数给用户的舒适度数据作为训练样本，然后将这些训练样本数据使用机器学习算法进行训练，得到舒适度模型。该舒适度模型可以用于评估各种环境检测数据的偏差下对用户舒适度的而影响。由于人工智能分类模型的训练方法、数据标注方式以及使用分类模型进行数据处理的具体流程和算法均为本领域技术人员所习知，因此在本实施例中不做赘述。
第一种选择限制或关闭的功能的方式，充分考虑了用户的舒适性感受，避免了
第二种限制和/或关闭环境调节设备200的部分功能的流程可以包括：将环境调节设备200恢复至设备噪音大于噪音阈值之前的运行状态，以实现限制和/或关闭环境调节设备200的部分功能的目的；并且在恢复运行状态的设定时间后，重新执行按照每项阶段目标参数与对应的检测数据的偏差调整环境调节设备200的运行状态的步骤。也即改变环境调节设备200的某项目标阶段参数后，发现噪音大于噪音阈值，则将环境调节设备200恢复至调整之前的状态，经过一段时间重新调整，如果经过设定时间后，目标参数与对应的检测数据的偏差仍然对用户的舒适度产生影响，可以重新按照偏差调整环境调节设备200的运行状态。例如目前调温状态需要提高空调器压缩机的频率。压缩机的频率提高后出现设备噪音大于噪音阈值的情况，则可以将压缩机的频率恢复至之前的状态，通过限制调温速度来保证噪音不超标。
第三种限制和/或关闭环境调节设备200的部分功能的流程可以包括：确定环境调节设备200完成各项功能导致的噪音大小；限制导致噪音最大的一项或多项功能；若在限制导致噪音最大的一项或多项功能之后，设备噪音仍大于噪音阈值，则关闭导致噪音最大的一项或多项功能。例如发现压缩机的噪音是导致睡眠环境噪音升高的主要因素，则可以首先选择限制压缩机的频率。
上述三种控制噪音的方式可以根据具体的调节要求进行选择。在不同的场景可以选择不同的控制方式。通过对噪音的限制，可以进一步提高用户的舒适感。
图4是根据本发明一个实施例的环境调节系统的控制方法在睡眠场景中应用的示意图。在该睡眠场景中，在t-1时刻，环境调节设备200开启运行， 在t时刻进入睡眠模式，在t+8时刻睡眠模式结束。整个睡眠过程包括第一阶段(t，t+1)、第二阶段(t+1，t+2)、第三阶段(t+2，t+5)、第四阶段(t+5，t+7)、第五阶段(t+7，t+8)共5个阶段。
在t时刻之前的阶段，是环境调节设备200在非睡眠模式下的运行阶段。环境调节设备200可以根据用户的设置或者根据其他自动运行的模式运行。
在t时刻开启睡眠模式，直至t+8时刻睡眠模式结束。以下分别对噪音(单位为dB)目标温度(单位为℃)、湿度(单位为％)、风速(也即风速档位)、风向(也即导风板位置)、空气质量(包括空气颗粒物(单位为μg/m 3)，CO2浓度(单位为ppm)、气味(也即香薰模块状态)、音量(单位为dB)、光线(也即情景灯状态)的阶段目标参数分别进行介绍。
对于目标温度，目标温度的初始目标温度为T，在睡眠模式启动后(t时刻)，第一阶段目标温度设置为T；在睡眠后1小时后(t+1时刻)，第二阶段目标温度调整为T+a；睡眠后2小时后(t+2时刻)，第三阶段目标温度调整为T+2a；睡眠后5小时后(t+5时刻)，第四阶段目标温度和第五阶段目标温度分别调整为T+a。从而符合了设定温度先升后降的舒适性要求。
对于目标湿度，在睡眠过程中可以将各阶段目标湿度始终维持在设定的舒适范围内，例如40％至60％之间。在北方冬季的干燥地区也可以在第五阶段适当提高目标湿度。
对于风速档位，在睡眠模式启动后(t时刻)，第一阶段目标风速档位可以适当降低，以期尽快达到设定温度的要求，在后续的阶段风速可以均设置为微风，避免出现风感。
对于风向，在睡眠过程中可以将各阶段目标风向始终保持为避免吹人的状态，也可以在第一阶段模拟自然微风。
对于空气颗粒物，在睡眠过程中可以将各阶段目标空气颗粒物浓度始终维持在设定的浓度阈值以下，例如35μg/m 3以下。
对于CO2含量，在睡眠过程中可以将前四阶段CO2含量始终维持在设定的含量阈值以下，例如600ppm以下，为了保证睡眠末段提高用户的起床的清新感，可以将第五阶段CO2含量阈值调低，例如500ppm。
对于香薰，可以在第一阶段和第五阶段，分别开启释放凝神以及提神的气味，例如薰衣草香和柠檬香。
对于灯光，在睡眠过程中可以尽量保持无光环境，在t+8时刻逐步提高 光线强度。
对于噪音，在睡眠过程中可以将各阶段目标噪音始终维持在设定的噪音阈值以下，例如30dB以下。对于声音特别敏感的用户还可以在第一阶段进一步下调噪音阈值。又例如，可以在第五阶段适当提高噪音阈值，将噪音阈值设置为40dB以下，从而满足环境调节设备200在起床前将睡眠环境调整至清晨的环境的运行状态变动要求。
需要说明的是，上述内容仅针对特定用户的睡眠趋势曲线以及阶段目标参数进行举例说明，本领域技术人员可以本实施例的基础上对具体的设置数值进行灵活调整和设定。
以第五阶段(t+7，t+8)为例，如果在需要降低CO2含量后开启新风出现噪音超标的情况后，可以评估温差、湿度偏差、以及CO2含量偏差对目标用户的舒适度影响，如果评估后发现当前温差对用户的舒适度影响较小，则可以选择下调压缩机频率以及风机转速。在另一种限制方式中，可以判断空调器、新风机、加湿器设备发出的噪音，如果空调器的噪音最高，则可以选择限制空调器的功能，来降低噪音。
上述睡眠场景仅为举例说明，本领域技术人员可以在上述介绍的内容，相应的得出本实施例的环境调节系统的控制方法在其他场景的应用方案，例如工作场景、会议场景等。
本实施例的环境调节系统的控制方法可能需要某一环境调节设备200或者多台环境调节设备200共同配合实现，例如温度调整可能涉及空调器、加热器等设备；湿度调整可能涉及空调器、加湿器、除湿机等；风力及风向调整可能涉及空调器、风扇等；空气颗粒物以及CO 2含量可能涉及新风机、净化器等；光线可能涉及自动窗帘、灯光等。
在另一些实施例中，可以将上述环境调节设备200集成于一台空调器中，该空调器可以具备加湿、新风等功能。从而利用一台空调器满足目标环境的整体舒适性调整。
应用本实施例的环境调节系统的控制方法，选择性地限制和/或关闭环境调节设备200的部分功能，尽量减少了因限制噪音对环境调节的影响。在保证环境舒适感的同时，还保证了限制噪音的效果。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根 据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
