详述
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
综上所述，目前，风扇装置不能在送风过程中根据具体需求灵活调节送风参数，不利于用户使用。
下面通过具体实施方式结合附图对本发明实施例作进一步详细说明。
实施例一：
本实施例提供一种风扇装置送风方法，请参见图1，包括：
S101：当检测到有人声，且风扇装置处于送风状态时，根据接收所述人声的情况计算声源信息；
S102：根据所述声源信息调整所述风扇装置的送风参数。
实时监控风扇装置周围的声音状况，当检测到有声音产生时，会获取该声音信号，并对该声音信号进行一系列的处理例如，噪声抑制、滤波等等得到音频数据流，然后对该音频数据流进行分析，滤除掉非人声的信号。当检测到获取到的声音信号中包括人声，而且风扇装置处于送风状态的时候，根据接收该人声的状况来计算声源信息。
具体地，计算声源信息的过程请参考图2，包括：
S201：计算人声的声源位置；
S202：计算第一夹角大小。
在S201中具体的计算人声的声源位置的方法可以是根据该人声到达风扇装置的麦克风阵列模块的各个麦克风的时间差来确定声源的位置。然后计算第一夹角的大小，在本实施例中，第一夹角是指声源和风扇装置的连线与风扇装置当前送风角度的角平分线形成的夹角。例如，请参考图3，为第一夹角说明图，其中角α为风扇装置当前送风角度，也即是，风扇装置的风扇头可以在角度α内摆动。射线L为角α的角平分线，通常，风扇装置的风扇头摆动到直线L的方向时，处于正前方。线段a为声源与风扇装置的连线，a与L之间形成的夹角β就是本实施例中所说的第一夹角。在声源信息中， 会包括该第一夹角的大小。
在计算出声源信息后，执行步骤S102，根据该声源信息对风扇装置的送风参数进行调整。具体地，送风参数可以包括送风角度，调整风扇装置的送风角度，调整后的送风角度的角平分线与风扇装置当前送风角度的角平分线重合，但是调整后的送风角度的大小为第一夹角的两倍。在如图3所示的示例中，角γ为调整后的送风角度，其角度大小为β的2倍；也即是说，进行调整后，风扇装置的风扇头可以在角度γ内摆动。当然，角γ的大小可能比α大，也可能比α小。在一种具体实施方式中，也可以设置当第一夹角的两倍的大小小于风扇装置当前送风角度时，不对风扇装置的送风角度进行调整，只在第一夹角的两倍的大小大于风扇装置当前送风角度时将送风角度调整为两倍第一夹角的大小。
在一种具体实施方式中，还可以结合语音来对风扇装置进行控制。具体地，在检测到有人声的时候，获取该人声的声音信息，并根据该声音信息来调整风扇装置的工作状态。声音信息主要包括人声的语义内容，例如，用户可能发出“开启风扇”的声音，在采集到声音信号后，识别该声音信号传达的意思，在本实施例中，可以直接以语音对应的文字内容来定义声音信息，也可以根据语音表达的意思来提取出对应的声音信息。当在声音信息中包括开启命令时，开启风扇装置的送风功能。开启命令可以是事先设置好的关键词，例如，“开启”、“打开”等等。具体的，识别声音信息中是否包括开启命令的过程可以直接将语音翻译成文本形式，并查看其中是否包含开启命令；例如，当设置了开启命令为对应的关键词为“开启”，当用户说出“开启风扇”的时候，会开启风扇的送风功能；另外，识别声音信息中是否包括开启命令的过程也可以解析用户的语音内容的含义，例如，当用户说：“想要打开风扇”，对用户的内容进行解析，也可以知道想要开启风扇，于是也会开启风扇的送风功能。
在声音信息包括将当前风速调整至目标风速的风速调整命令时，将风扇装置的送风风速调整至目标风速。有时候，用户可能感觉风扇的风速太大了或者太小了，可以下发风速调整命令在命令中包括目标风速的关键词，例如，可以设置目标风速“声档、2档、3档”等等。具体的，识别声音信息中是否 包括调整命令的过程与识别开启命令的过程类似。可以直接将语音翻译成文本形式，并查看其中是否包含调整命令，也可以解析用户的语音内容的含义，看其是否包含调整命令。在声音信息包括停止命令时，停止风扇装置的送风功能，关闭风扇装置。与上述开启命令和调整命令类似，结束命令也可以采用关键词的形式，例如，可以设置“结束送风、停止风扇”等作为关键词语；具体识别声音信息中是否包括该结束命令的方法与上述识别声音信息中是否包开启命令和调整命令的过程类似。风扇装置停止送风后，进入待唤醒状态，可以对风扇装置持续供电，风扇装置可以持续收集周围环境的声音，当检测到有人声，并且判断出该人声的声音信息中包含有开启命令时，可以再次唤醒该风扇装置，开启其送风功能。
因为应用在风扇上的处理器对数据处理能力要求不需要太高，可能不会选用性能很好的硬件，所以考虑到性能的提升，在一种具体实施方式中，可以将获取到的声音信息进行暂时性的存储，并周期性的来识别声音信息中是否包括开启命令，停止命令，调整命令等等。对于具体周期定为多少，可以根据具体需求灵活设置。
在本实施例的一种具体实施方式中，还会获取风扇装置周围的环境状况的图像，对获取到的图像进行分析，主要包括分析图像中的各人物的分布，根据各人物的分布情况对送风装置的送风参数进行调整。在本实施例中，人物分布状况主要包括人物分布的密集程度和人物分布范围。具体分析人物分布的密集程度和人物分布范围可以采用人脸识别技术来识别图像中的人物。
图像通常是由风扇装置自身拍摄的，也就是说拍摄的图片可以反映风扇装置所在角度对应的人物分布状况，因此，可以将其作为送风参数调整的科学依据。对图像中的人物密集程度进行分析，并将获得的结果与预设分布规则进行比对，匹配出相应条目(可以是档位或者送风频率)，也就是匹配出相应档位或送风频率，并根据匹配的条目调整风扇的送风频率，其中，在预设分布规则中定义了分布的密集程度和对应的针对风扇装置的送风参数的调整策略。例如，密集程度可以以每平米内用户数量来衡量；分布规则中定义，当密集程度达到每平米内用户数量为2时，将风速调整至2档；当密集程度达到每平米内用户数量为3时，将风速调整至3档。也可以定义送风频率， 也即是风扇装置的摆动频率。上述举例，仅对本实施例进行说明而不作为对本实施例的限制。通常，人物密集度越高，需要将风速调整的越高；人物密集度越高，送风频率的越低，风扇头摆动得越慢，在人物密集度高的地方较长时间停留；人物密集度越低，送风频率越高，风扇头摆动得越快，可以同时调整送风风速和送风频率两个参数，也可以只调整其中一个参数。另外，还可以根据人物分布范围来调整风扇装置的送风角度，也即是送风范围，根据检测到人物的最大范围即人脸分布的最大范围重新调整设定摇头送风的范围。
在一种具体实施方式中，可以设置周期性地来获取风扇装置周围的环境状况的图像，并对图像分析，调整送风参数。
本发明实施例提供的风扇装置送风方法，根据声源对用户进行定位，从而自动调整风扇装置的送风角度，送风范围；而且结合语音识别技术，用户可以使用语音发送各种控制命令，例如，开启命令，调整风速命令，停止命令等等；另外，还使用图像识别技术，分析出人物分布范围和密集程度，对风扇装置的送风参数做出相应的调整。全程都可以不需要用户手动进行任何操作，方便用户使用，使得风扇装置更加智能。
实施例二：
本实施例提供一种风扇装置，请参考图4，风扇装置包括麦克风阵列模块41、麦克风声卡42和处理器43。
麦克风阵列模块41设置成：实时获取风扇装置周围的声音信号，并将所述声音信号发送个麦克风声卡。在本实施例中，麦克风阵列模块41可以是但不限于四麦克风阵列。
麦克风声卡42设置成：接收麦克风阵列模块41发送的声音信号，并对声音信号进行处理，将处理后得到的音频数据流发送给处理器43。对声音信号进行的处理可以包括噪声抑制、滤波等等，以滤除掉非人声的信号。在本实施例中，麦克风声卡42可以是但不限于四麦克风声卡。
处理器43设置成：接收麦克风声卡42发送的音频数据流，并从中分析出是否有人声，当分析出有人声，且风扇装置处于送风状态时，根据麦克风阵列模块41接收所述人声的情况计算声源信息；并根据声源信息调整风扇装 置的送风参数。
风扇装置还包括摇头电机44，在本实施例中，摇头电机44可以选用步进电机。
处理器43具体的计算人声的声源位置的方法可以是采用声音相位关系来确定声源的位置。然后计算第一夹角的大小，在本实施例中，第一夹角是指声源和风扇装置的连线与风扇装置当前送风角度的角平分线形成的夹角。在声源信息中，会包括该第一夹角的大小。然后，处理器43根据该声源信息对风扇装置的送风参数进行调整。具体地，送风参数可以包括送风角度，调整风扇装置的送风角度，调整后的送风角度的角平分线与风扇装置当前送风角度的角平分线重合，但是调整后的送风角度的大小为第一夹角的两倍。调整后的送风角度可以比风扇装置当前送风角度大也可以比风扇装置当前送风角度小。具体调整送风角度的方式可以是控制摇头电机44的摆动范围，也即是，控制和调整摇头电机的旋转角度。
在一种具体实施方式中，也可以设置当第一夹角的两倍的大小小于风扇装置当前送风角度时，不对风扇装置的送风角度进行调整，只在第一夹角的两倍的大小大于风扇装置当前送风角度时将送风角度调整为第一夹角的两倍的大小。
在一种具体实施方式中，处理器43还可以结合语音来对风扇装置进行控制。当处理器43分析出有人声时，获取人声的声音信息，声音信息为人声的语义内容；处理器43根据声音信息调整风扇装置的工作状态。声音信息主要包括人声的语义内容，以直接以语音对应的文字内容来定义声音信息，也可以根据语音表达的意思来提取出对应的声音信息。当在声音信息中包括开启命令时，处理器43控制开启风扇装置的送风功能。开启命令可以是事先设置好的关键词，具体的，识别声音信息中是否包括开启命令的过程可以直接将语音翻译成文本形式，并查看其中是否包含开启命令；也可以解析用户的语音内容的含义，对用户的内容进行解析判断是否包含开启命令。在声音信息包括将将当前风速调整至目标风速的风速调整命令时，处理器43控制风扇装置的送风风速调整至目标风速。具体的，识别声音信息中是否包括调整命令的过程与识别开启命令的过程类似。可以直接将语音翻译成文本形式，并查 看其中是否包含调整命令，也可以解析用户的语音内容的含义，看其是否包含调整命令。在声音信息包括停止命令时，停止风扇装置的送风功能，处理器43控制关闭风扇装置。风扇装置停止东风后，进入待唤醒状态，电源可以对风扇装置持续供电，麦克风阵列模块41可以持续收集周围环境的声音，当处理器43识别出有人声，并且判断出该人声的声音信息中包含有开启命令时，可以再次唤醒该风扇装置，开启其送风功能。
在一种具体实施方式中，处理器43可以将获取到的声音信息进行暂时性的存储，并周期性的来识别声音信息中是否包括开启命令，停止命令，调整命令等等。对于具体周期定为多少，可以根据具体需求灵活设置。
风扇装置还设置有摄像头模组45，设置成：拍摄风扇装置周围环境状况的图像，并将图像发送给处理器43。处理器43对获取到的图像进行分析，主要包括分析图像中的各人物的分布，根据各人物的分布情况对送风装置的送风参数进行调整。在本实施例中，人物分布状况主要包括人物分布的密集程度和人物分布范围。具体分析人物分布的密集程度和人物分布范围可以采用人脸识别技术来识别图像中的人物。
处理器43对图像中的人物密集程度进行分析，并将获得的结果与预设分布规则进行比对，匹配出相应条目，也就是匹配出相应的档位或者送风频率，并根据匹配的条目调整风扇的送风风速。在预设分布规则中定义了分布的密集程度和对应的针对风扇装置的送风参数的调整策略。调整策略可以包括，调整风扇装置的送风风速和送风频率。通常，人物密集度越高，需要将风速调整的越高；人物密集度越高，送风频率越低，风扇头摆动得越慢；人物密集度越低，送风频率越高，风扇头摆动得越快。可以同时调整送风风速和送风频率两个参数，也可以只调整其中一个参数。在一种具体实施方式中，可以设置处理器43周期性地来获取风扇装置周围的环境状况的图像，并对图像分析，调整送风参数。
