本发明的实施方式
在本发明实施例中，流程的执行主体为空调。该空调内设有智能处理模块以及采集模块，通过对采集模块获取的环境参数进行处理运算，确定当前空调的运行参数，控制空调运行。图1示出了本发明第一实施例提供的空调的控制方法的实现流程图，详述如下：
在S101中，获取空调的作用空间的环境参数；所述环境参数包括：室外温度、所述作用空间内用户的当前个数、所述作用空间内用户的平均体表温度，以及所述空调出风形成的各个扇形区域内的用户密度；其中，各个所述扇形区域具体为：所述空调的摆叶位于各个预设的摆动角度时形成的出风区域。
在本实施例中，空调作用空间的环境包括室内环境以及室外环境两部分。其中，室内环境参数包括作用空间内用户的个数、作用空间内用户的平均体表温度以及空调出风形式的各个扇形区域内的用户密度。由于空调在通过摆叶进行扫风的过程中会形成一个可覆盖区域，而空调某一时刻的出风区域是小于可覆盖区域的一个扇形区域，即可覆盖区域是由该扇形区域以空调为中心、以摆叶在各个预设的摆动角度进行送风时所形成的区域。因此，可以将可覆盖区域划分为多个边界相邻但互补重叠的扇形区域，即空调的摆叶位于各个预设的摆动角度时形成的出风区域，而基于该扇形区域的面积以及该面积包含的用户人数，则可以确定该扇形区域的用户密度。
在本实施例中，空调的作用空间具体为：环境温度受空调调控的区域所构成的空间，即可被空调影响的空间。
除上述室内环境参数外，空调采集的环境参数还包括室外温度，可选地，还可以包括室 外湿度以及光照强度。由于湿度以及光照强度对于空调的温度调节也存在一定的影响，例如光照强度越大，则表示太阳光线的热辐射影响越大，此时若需要维持室内处于稳定某一温度，相对于光照强度较弱的环境而言，空调的输出功率会较高；同样地，室外湿度也会对用户的温度感知有一定的影响，湿度较大，则表示空气中水的含量越高，而水的比热容较大，因此若需要对室内进行降温，则所需的降温时间较长，可以适当提高空调的输出功率。
在本实施例中，空调可通过内置不同类型的传感器，采集上述多项环境参数。空调可通过温度传感器获取室外温度；特别地，该温度传感器可放置于空调室外机处，然后空调通过蓝牙通信、无线局域网通信或串口通信等方式与温度传感器进行通信连接，获取温度传感器反馈的室外温度。空调可以通过超声波接发模块，向作用空间内的多个预设的角度发射超声波并接收超声波反馈的回波信号，确定该房间内包含的用户个数。空调还可以通过热辐射传感器，获取房间内的热辐射图像，并基于该热辐射图像确定该房间内的用户个数以及各个用户的表面温度，继而求出该室内用户的平均体表温度，并基于该热辐射图像，确定各个扇形区域的用户密度。
优选地，空调会以预设的时间间隔执行S101的相关操作，从而实现随着环境参数的变化自动调整空调的运行参数的目的。特别地，该时间间隔根据空调的运行状态的不同可以适应性地变化。例如，空调处于关机或待机状态，则该时间间隔可以较长，例如10分钟或30分钟；而空调处于运行状态下，则该时间间隔可以较短，例如1分钟或30秒。
在S102中，将所述室外温度、所述平均体表温度以及所述当前个数导入到空调输出功率的转换模型，确定所述空调的输出功率。
在本实施例中，空调在获取了上述环境参数后，则将环境参数分为两类，分别计算空调的输出功率以及空调在各个扇形区域的停留时间。其中，用于计算空调的输出功率的环境参数包括：室外温度、室内用户的平均体表温度以及用户个数。
在本实施例中，空调将室外温度、平均体表温度以及作用空间内用户的个数导入到预设的空调输出功率的转换模型内，计算当前时刻空调所在房间所对应的输出功率是多大。具体地，室外温度越高，则空调的输出功率越大；用户的平均体表温度越高，则空调的输出功率越大；当前个数越多，则散发的热量越多，因此空调的输出功率也越大。因此，基于上述三个环境参数与输出功率之间的关系，可以确定该转换模型可为：
P＝αT 室外·βT 表·γQ；P∝T 室外，P∝T 表，P∝Q；
其中，P为空调的输出功率；T 室外为室外温度，T 表为平均体表温度，Q为当前个数。α、β以及γ为调整系数。上述三项参数均与空调的输出功率成正相关。
可选地，空调还可以根据室外温度以及用户的体表温度，确定空调的输出温度。用户可以在空调内设置一个目标温度，即空调会维持所覆盖的房间在该目标温度。其中，若室外温度以及用户的体表温度与该目标温度的差值越大，则空调的运行温度则会越低；若室外温度以及用户的体表温度与该目标温度的差值越小，则空调的运行温度会越高但依然会低于目标温度，从而基于上述两个参数，可以确定该空调的运行温度。
可选地，空调还可以获取室内湿度，并将该室内湿度与预设的湿度范围进行比对，确定是否需要开启增湿模式，或是开启除湿模式。
进一步地，作为本发明另一实施例，所述空调输出功率的转换模型具体为：
Figure PCTCN2018083289-appb-000001
其中，所述P 实际为空调的输出功率；所述N为所述当前个数；所述T 1为室外温度；所述T 2为所述平均体表温度；所述δ为预设的调整系数；所述P 基准所述空调的基准输出功率。
在本实施例中，空调会确定室外温度与用户的平均体表温度之差，若上述差值越大，则表示用户的舒适度较低，此时需要通过加大功率来调整室内温度，以尽快调整用户的舒适度；若上述差值越小，则表示用户的舒适度较高，此时可以适当减少功率，实现节能的效果。
在本实施例中，空调还会根据当前个数确定一个加权系数，该加权系数即为
Figure PCTCN2018083289-appb-000002
由于tanh(δN)函数的特性是在个数较低时，其数值会小于1，而人数较少的情况下一般是空调处于刚刚开启的阶段，此时室内温度与外界温度基本保持持平，因此空调的输出功率不能过低，避免调整温度的时间过长，因此通过tanh(δN)函数的特性刚好可以弥补上述情况的问题，在人数较少时，tanh(δN)值小于1，会保证输出功率不至于过低，而当人数较多时，tanh(δN)的数值会近似1，从而保证输出功率会随着人数的增大而呈现正比例增大的关系，满足实际空调的调整需求。
在本发明实施例中，空调可通过室外温度、平均体表温度以及用户的个数确定一个加权系数，并基于该加权系数对基准输出功率进行加权运算，确定当前合适的输出功率，实现空调输出功率动态调整的目的，提高了空调参数调整的效率。
在S103中，计算各个所述用户密度之间比值，并基于所述比值确定所述摆叶在各个所述摆动角度的停留时间。
在本实施例中，空调的摆叶并非匀速摆动的，而是会根据不同扇形区域中包含的用户密度，确定摆叶在各个扇形区域对应的预设角度的停留时间。具体地，空调获取各个扇形区域的用户密度的方式可以为：空调通过例如超声波接发模块或红外感应模块，获取该房间内的 用户分布图，并基于该用户分布图以及每个扇形区域所覆盖的面积，确定该扇形区域内用户的个数，从而确定该用户密度。
在本实施例中，定义空调的摆叶在可摆动范围内摆动往返一次所需的时间为一个摆动周期，因此空调的摆叶在预设摆动角度的停留时间可根据该用户密度与摆动周期计算得到，具体的计算过程如下：
Figure PCTCN2018083289-appb-000003
其中，T(i)为摆叶在第i个扇形区域对应的摆动角度的停留时间；ρ i为第i个扇形区域的用户密度；T为摆动周期；n为扇形区域的个数。
举例性地，图2为本发明一实施例提供的空调出风覆盖区域的示意图。参见图2所示，S 总为空调出风总的覆盖区域；S 1～S 4为摆叶在四个预设摆动角度时所出风形成的扇形区域。其中，S 1～S 4的用户的个数分别为2个、1个、3个以及1个。基于上述各个扇形区域的用户个数以及扇形区域的覆盖面积，可以确定各个扇形区域的用户密度，从而得到各个预设的摆动角度的停留时间。例如各个扇形区域的面积均为1平方米，则上述四个扇形区域的用户密度粉笔为：2人/m 2、1人/m 2、3人/m 2以及1人/m 2。若摆动周期为14s，则
Figure PCTCN2018083289-appb-000004
Figure PCTCN2018083289-appb-000005
在S104中，控制所述空调以所述输出功率以及所述停留时间运行。
在本实施例中，空调在确定了输出功率以及在各个扇形区域的停留时间后，则基于上述两个参数的值控制空调运行，当然若在S103中除了确定空调的输出功率外，还确定了输出温度以及是否开启除湿增湿功能，则本次控制运行参数的个数为四个。
以上可以看出，本发明实施例提供的一种空调的控制方法通过自动获取空调所在房间的环境参数，并基于环境参数确定该空调的输出功率以及摆叶在各个所述扇形区域的停留时间，并基于上述参数控制空调运行，无需用户手动调节，可以根据当前的环境配置合适的运行参数，减少不必要的能源消耗，实现节能的目的。
图3示出了本发明第二实施例提供的一种空调的控制方法S101的具体实现流程图。参见图3所示，相对于图1所述实施例，本实施例提供的一种空调的控制方法中S101包括S1011～S1012，具体详述如下：
在S1011中，若检测到设置于所述作用空间内用于检测用户进出所述作用空间的电极板组中的至少两组电极板的电荷量均发生跳变，则获取每组电极板各自对应的跳变时间；其中，所述每组电极板之间相互独立且隔离，所述每组电极板包括两个相对设置的电极板，且每组电极板与所述空调之间的距离值不同。
在本实施例中，作用空间可以设置有电极板组，该电极板组用于检测用户进出作用空间，即用户可在电极板组中的每一组电极板间进行同行，通过改变各组电极板间的介电常数，检测是否有用户进出作用空间。具体地，该电极板组可设置于所作用空间的出入口的门框上。该电极板组中包含至少两组电极板，在本实施例中用第一组电极板以及第二组电极板进行命名。每组电极板包括两个相对设置的电极板，若该组电极板设置于门框上，则该组电极板的两个电极板可以分别设置于门框的对边上，构成一个类似电容的结构，需要说明的是，每组电极板处于独立的直流电路中，当接通该直流电路的开关时，该组电极板上的每个电极板会聚集一定的电荷量。为了便于描述，现限定第一组电极板上包含的两个电极板分别为第一电极板以及第二电极板，第二组电极板上包含的两个电极板分别为第三电极板以及第四电极板。由于在没有人经过时，第一电极板与第二电极板之间的介质为空气，该电荷量是保持稳定的。然而人体是具有一定的导电性质的，与空气的介电常数不相同，若用户在进出门框时，从第一电极板与第二电极板间穿过，则会改变第一电极板与第二电极板之间绝缘介质的介电常数，从而导致两个电极板会进行充电或放电的过程，改变两个电极板上的电荷量。同样道理，对于第三电极板与第四电极板也可以同样会出现上述特征。基于上述原理，空调可通过检测第一组电极板的电荷量以及第二组电极板上的电荷量是否发生跳变，从而确定是否有人经过门框，判断空调作用空间的人数是否发生了变化。
在本实施例中，由于每组电极板之间与空调之间的距离并不相同，即有一组电极板会距离室外较近，而另一组电极板距离室内较近，从而基于不同组的电极板的跳变时间，则可以确定用户是从室外进入室内，抑或是从室内走出到室外，从而判定是对用户人数进行增加操作或是减少操作。
图4示出了本发明实施例提供的一种门框上四个电极板的放置示意图。参见图4所示，第一电极板与第二电极板的板面是彼此相对的，可看似一个电容，构成第一组电极板，并且相对第二组电极板，即由第三电极板与第四电极板构成的另一组电极板，是较为靠近室内的；而第三电极板与第四电极板的板面也是彼此相对的，相对于第一电极板与第二电极板而言是较为靠近室外的。当然，在图4中上述4个电极板均放置于门框的左右两侧，但不限于此，第一电极板与第二电极板可放置于门框的上下两条对边上，此时，第三电极板与第四电极板既可以放置于门框的左右两对边上，也可以放置于上下两对边上，只要保证第三电极板与第四电极板相对于第一电极板与第二电极板而言是靠近室外即可，即距离空调的距离较远。
在本实施例中，第一电极板与第二电极板的直流电路上设有一电荷感应模块，该电荷感应模块用于检测第一电极板和/或第二电极板的电荷量的大小，当电荷感应模块检测到第一电极板和/或第二电极板的电荷量发生变化时，即向空调发送一个电荷跳变指令，当空调接 收到该电荷跳变指令后，则识别该第一电极板的电荷量发生变化，并将接收到电荷跳变指令的时刻记录有第一跳变时间。同理，检测第三电极板电荷量是否存在跳变以及获取第二跳变时间的方式与上述论述的情况相同，在此不再赘述。当然，若空调是安置于门框附近，则空调还可以直接与第一电极板所在的直流电路以及第三电极板所在的另一直流电路直接相连，通过分别与两个直流电路连接的管脚的信号输入波形，判定是否有类似于脉冲信号的输入波形，从而确定是否存在电荷量跳变的情况。
在S1012中，基于各组电极板的所述跳变时间统计所述作用空间内用户的当前个数。
在本实施例中，空调检测到第一跳变时间早于第二跳变时间，则表示存在用户从室内移动到室外，即室内的人数减少了，因此需要对室内用户的个数进行调整。
在本实施例中，空调检测到第一跳变时间晚于第二跳变时间，则表示存在用户从室外移动到室内，即室内的人数增加了，需要对作用空间内用户的个数进行调整。
在本发明实施例中，通过在作用空间的门框上设置两组电极板，并基于电极板上的电荷量变化，判定是否存在用户进入或离开空调作用空间，从而实现对室内用户的人数进行增加调整，与现有的室内人数识别的技术相比，制作成本较低，并且改造较为方便，添加4个电极板即可，降低了本发明提供的空调的造价。
图5示出了本发明第三实施例提供的一种空调的控制方法S1012的具体实现流程图。参见图5所示，相对于图3所述实施例，本实施例提供的一种空调的控制方法中S1012包括以下步骤，具体详述如下：
在S501中，检测第一跳变时间是否早于第二跳变时间。
在S502中，若所述电极板组中的第一组电极板的第一跳变时间早于第二组电极板的第二跳变时间，则获取所述第一组电极板在所述第一跳变时刻的第一电荷量。
在本实施例中，空调接收到的可以为第一电极板的电荷量的变化曲线图，在该情况下，空调会获取在第一跳变时刻该第一电极板的电荷量的峰值，将该峰值对应的数值作为第一电荷量。由于经过第一电极板与第二电极板之间的区域时，人数不同所引起的充放电的程度也不同，反映在电荷量上即跳变时刻该第一电荷量的数值会不同。因此，空调可以通过获取第一电荷量的大小，确定该跳变时刻，同时离开室内的人数具体为多少。
当然，除了该变化曲线图外，空调若采用的是将管脚直接接入直流电路上的方式检测第一电极板是否存在跳变，则可以基于第一电极板发生跳变时出现的类脉冲信号的信号幅值转换为电荷量，作为第一电荷量。
在S503中，基于所述第一电荷量确定用户减少的减少个数，并根据所述减少个数调整所述作用空间内用户的当前个数；所述第一组电极板与所述空调的第一距离值小于所述第二 组电极板的第二距离值。
在本实施例中，空调预设有跳变电荷量与通行人数的对应关系表，在获取了第一电荷量后，可以通过该对应关系表查询本次通行人数的个数，将该通行人数的个数作为用户减少的减少个数，并相应地减少作用空间内用户的个数，实现实时调整用户的个数的目的。
在S504中，若所述第一跳变时间晚于所述第二跳变时间，则获取所述第二组电极板在所述第二跳变时刻的第二电荷量。
在本实施例中，由于S504的实现方式与S502的实现方式完全相同，具体参数可参见S502的相关描述，在此不再赘述。
在S505中，基于所述第二电荷量确定用户增加的增加个数，并根据所述增加个数调整所述作用空间内用户的当前个数。
在本实施例中，需要说明的是，S505查询第二电荷量对应的增加个数时，依然可以采用跳变电荷量与通行人数的对应关系表，特别地，若第一电极板与第二电极板构成的电容结构的电容值，以及第三电极板与第四电极板构成的电容结构的电容值相同，则确定增加个数的对应关系表与确定减少个数的对应关系表是完全相同的，因此该情况下，空调可以只是保存一个对应关系表即可。当然，若上述两对电极板构成的电容结构的电容值不相同，则空调需要获取两个与两对电极板的电容值相匹配的对应关系表，从而确定增加个数以及减少个数。
在本实施例中，空调在确定了第二电荷量后，可以通过查询对应关系表，确定第二电荷量所对应的增加人数，并相应地增加作用空间内用户的个数，实现实时调整用户的个数的目的。
在本发明实施例中，通过获取跳变时刻的电荷量，确定通行的人数，实现准确调整作用空间内用户的个数的目的，提高控制的准确率。
图6示出了本发明第四实施例提供的一种空调的控制方法的具体实现流程图。参见图6所示，相对于图1至图5所述实施例，本实施例提供的一种空调的控制方法在所述获取空调作用空间的环境参数之前，还包括：S601～S603，具体详述如下：
在S601中，以预设的时间间隔获取当前所述作用空间的室内温度。
在本实施例中，若空调处于待机或关机状态，则空调会以预设的时间间隔获取当前作用空间的室内温度，并将该室内温度与预设的启动温度进行比较，判定是否当前温度是否满足空调的启动条件。若当前的室内温度小于或等于预设的启动温度，则保持关机状态或待机状态，当然，在空调处于启动时，也可以通过获取当前的室内温度，与预设的启动温度进行比较，判定是否需要关闭空调运作，减少能量的消耗；反之，若室内温度大于预设的启动温度，则需要进一步判断当前空调的作用空间内是否存在用户，因此执行S602的相关操作。
在S602中，若所述室内温度在预设的温度范围外，则获取所述作用空间内用户的当前个数。
在本实施例中，空调若检测到室内的温度大于预设的启动温度，则表示当前室内的温度较高，可能需要通过空调进行降温。在该情况下，空调会确定该作用空间内用户的个数，并将该用户的个数与预设的启动个数进行比对，确定是否满足人数启动条件。若用户的个数小于或等于预设的启动个数，则保持空调处于待机或关机状态；反之，若用户的个数大于预设的启动个数，则执行S603的相关操作。
优选地，该预设的启动个数为0，当作用空间内的有至少一个用户且室内温度较高时，则启动空调；若作用空间内不存在用户，即便室内温度较高也保持空调处于关机或待机状态，避免不必要的资源浪费。
在S603中，若所述当前个数大于预设的启动个数，则启动所述空调，并执行获取空调作用空间的环境参数的操作。
在本实施例中，当检测到室内空间的用户个数大于预设的启动个数后，并且当前的室内温度也高于启动温度，则启动该空调，并获取其他环境参数，实现自动调整空调运行参数的目的。
在本发明实施例中，通过设置温度启动条件以及人数启动条件，实现空调自动启动，并且不会造成资源浪费，提高了空调的节能效率。
应理解，上述实施例中各步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
