具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本申请中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
由背景技术可知，用户在需要空调内机朝着用户自身送风时，用户需要通过遥控器手动调整空调内机的摆叶和导板，从而调整空调内机的送风方向，但是前述调整送风方向的方式需要较长的时间才能调整好空调内机的送风方向，用户的使用体验较差。
因此，本发明实施例提供一种空调控制方法、空调内机、遥控器及系统，空调内机利用遥控器相对于空调内机的相对位置坐标，从送风轨迹集合中确定最终送风轨迹，并根据最终送风轨迹调整空调内机的送风方向，以节约用户调整送风方向的时间和提高用户的使用体验。
参见图1，示出了本发明实施例提供的一种空调控制方法的流程图，该空调控制方法包括以下步骤：
步骤S101：遥控器检测遥控器的第一位置坐标。
需要说明的是，本发明实施例中所涉及的遥控器的类型包括但并不限于：与空调内机配套的空调遥控器、万能遥控器和具有遥控器功能的移动终端(比如智能手机)，在此对于遥控器的类型不做具体限定。
在具体实现步骤S101的过程中，遥控器通过自身的传感器(比如超声波传感器)检测遥控器相对于房间(空调内机所在的房间)的坐标，遥控器检测得到的坐标即为第一位置坐标(遥控器相对于房间的坐标)。
遥控器获取第一位置坐标的具体方式如下：
遥控器通过超声波传感器，分别向垂直方向、第一水平方向和第二水平方向发射超声波，并分别记录开始向垂直方向、第一水平方向和第二水平方向发射超声波的第一时间， 其中，第一水平方向与第二水平方向垂直。
需要说明的是，超声波在空气中传播时碰到墙面会反射回来，也就是说，遥控器在向垂直方向、第一水平方向和第二水平方向发射超声波时，当超声波碰到垂直方向的墙面、第一水平方向的墙面和第二水平方向的墙面时会反射回来。
分别记录接收到垂直方向、第一水平方向和第二水平方向的反射波的第二时间，即记录接收到垂直方向的反射波的时间、记录接收到第一水平方向的反射波的时间和记录接收到第二水平方向的反射波的时间。
需要说明的是，由于超声波在空气中的传播速度可知，因此可通过发射超声波的时间和接收反射波的时间，确定发射点距墙面的距离。
也就是说，结合超声波在空气中的传播速度，利用第一时间和第二时间，确定遥控器距离垂直方向、第一水平方向和第二水平方向的墙面的距离，即利用向垂直方向发射超声波的第一时间和接收到垂直方向的反射波的第二时间，确定遥控器距离垂直方向的墙面的距离，利用向第一水平方向发射超声波的第一时间和接收到第一水平方向的反射波的第二时间，确定遥控器距离第一水平方向的墙面的距离，利用向第二水平方向发射超声波的第一时间和接收到第二水平方向的反射波的第二时间，确定遥控器距离第二水平方向的墙面的距离。
利用遥控器距离垂直方向的墙面的距离、第一水平方向的墙面的距离和第二水平方向的墙面的距离，确定遥控器的第一位置坐标(三维坐标)。
为更好解释说明遥控器如何检测第一位置坐标的过程，通过图2示出的遥控器检测第一位置坐标的示意图进行举例说明，需要说明的是，图2仅用于举例说明。
假设该遥控器的超声波传感器设置在遥控器顶部，如图2所示，遥控器通过超声波传感器向竖直向上方向(垂直方向)、水平向前方向(第一水平方向)和水平向右方向(第二水平方向)发射超声波，并记录发射超声波的第一时间。
遥控器分别记录接收到竖直向上方向、水平向前方向和水平向右方向的反射波的第二时间，并利用超声波在空气中的传播速度、第一时间和第二时间，确定遥控器的第一位置坐标。
比如：利用超声波在空气中的传播速度、向竖直向上方向发射超声波的第一时间和接收到竖直向上方向的反射波的第二时间，即可确定得到遥控器距离房间天花板的距离Z y，同理，通过上述方式，可确定得到遥控器距离房间右边(水平向右方向)墙面的距离X y，以及确定遥控器距离房间前边(水平向前方向)墙面的距离Y y，也就是说，遥控器的第一位置坐标为(X y，Y y，Z y)。
步骤S102：遥控器将第一位置坐标发送给空调内机。
在具体实现步骤S102的过程中，遥控器检测得到第一位置坐标后，遥控器将第一位置坐标发送给空调内机。
步骤S103：空调内机根据第一位置坐标和预先获取的空调内机的第二位置坐标，确 定遥控器相对于空调内机的相对位置坐标。
需要说明的是，空调内机在房间的位置是固定的，因此空调内机预先检测空调内机相对于房间的坐标，空调内机预先检测得到的坐标即为第二位置坐标(三维坐标)，也就是说，第二位置坐标为空调内机相对于房间的坐标。
进一步需要说明的是，空调内机检测得到第二位置坐标的方式，可参见上述本发明实施例步骤S101中遥控器检测第一位置坐标的内容，在此不再进行赘述。
在具体实现步骤S103的过程中，需要说明的是，以空调内机的出风口中心作为三维笛卡尔坐标系原点(0，0，0)，空调内机通过第一位置坐标和第二位置坐标，即可确定遥控器相对于空调内机的相对位置坐标。
比如：假设第一位置坐标为(X y，Y y，Z y)，第二位置坐标为(X k，Y k，Z k)，则遥控器相对于空调内机的相对位置坐标为(X y-X k，Y y-Y k，Z y-Z k)，以(X 1，Y 1，Z 1)表示(X y-Xk，Y y-Yk，Z y-Zk)。
步骤S104：空调内机确定预设的送风轨迹集合中与相对位置坐标对应的送风轨迹为最终送风轨迹。
需要说明的是，空调内机的摆叶左右摆动不同角度(摆叶角度)可以向左右不同位置送风，空调内机的导板上下摆动不同角度(导板角度)可以向上下不同位置送风，也就是说，通过不同的摆叶角度和不同的导板角度进行组合，可得到多个送风轨迹，不同送风轨迹对应不同送风方向，即每个送风轨迹存在自身对应的送风方向、摆叶角度和导板角度。
利用上述得到的多个送风轨迹，构建送风轨迹集合，该送风轨迹集合中包括多个送风轨迹。
可以理解的是，送风轨迹为曲面，也就是不同的送风轨迹为不同的曲面，即可以通过不同的曲面表示不同的送风轨迹。由于曲面是由不同的坐标点组成的，因此可以利用曲面方程表示曲面，即每个送风轨迹对应一曲面方程。
为更好解释说明上述关于通过曲面表示送风轨迹的内容，通过图3示出的送风轨迹对应的曲面方程的曲面示意图进行举例说明，需要说明的是，图3仅用于举例。
针对每一个送风轨迹，确定该送风轨迹对应的区域(比如通过风场模拟软件模拟得到该区域)，并从该区域中提取出n个三维数据点，将n个三维数据点拟合成曲面方程，该曲面方程对应的曲面即为该送风轨迹，该曲面方程对应的曲面示意图如图3所示。
在具体实现步骤S104的过程中，由上述内容可知，每一曲面由多个坐标点组成，因此，空调内机利用相对位置坐标，确定送风轨迹集合中与该相对位置坐标对应的送风轨迹为最终送风轨迹。
可以理解的是，与相对位置坐标对应的送风轨迹是指：该相对位置坐标位于该送风轨迹对应的曲面上，或者，该相对位置坐标在该送风轨迹对应的曲面的一定范围内。
步骤S105：空调内机根据最终送风轨迹，调整空调内机的送风方向。
由前述内容可知，每一送风轨迹都存在对应的导板角度和摆叶角度，因此在具体实现 步骤S105的过程中，空调内机确定与最终送风轨迹对应的导板角度和摆叶角度，空调内机根据与最终送风轨迹对应的导板角度调整空调内机的导板，使导板的角度为该导板角度，空调内机根据与最终送风轨迹对应的摆叶角度调整空调内机的摆叶，使摆叶的角度为该摆叶角度。
通过上述调整，使空调内机的送风轨迹与最终送风轨迹一致，从而使空调内机的送风方向对准遥控器。
为更好解释说明上述步骤S101至步骤S105中的内容，结合图4示出的内容，通过以下示例进行举例说明。
需要说明的是，预先在遥控器中设置一按键功能(可通过单独设置的按键触发或者通过组合按键触发)，该按键功能用于启动空调内机的“定向送风”功能。
用户通过遥控器触发用于启动空调内机的“定向送风”的按键功能(遥控器和空调内机获取到相应的触发指令)，遥控器检测第一位置坐标并将第一位置坐标发送给空调内机。空调内机根据第一位置坐标和第二位置坐标确定遥控器相对于空调内机的相对位置坐标(X 1，Y 1，Z 1)，空调内机确定与该相对位置坐标对应的最终送风轨迹的曲面方程为F(X，Y，Z)＝A 1+B 1X 3+C 1Y 3+D 1Z 3，其中，F表示曲面，A、B、C和D为曲面方程的系数，需要说明的是，不同的送风轨迹对应不同的A、B、C和D。
假设最终送风轨迹对应的摆叶角度为左30度，最终送风轨迹对应的导板角度为上40度，空调内机将摆叶角度调整至左30度，以及将导板角度调整为上40度，使空调内机的送风方向对准遥控器，空调内机利用最终送风轨迹调整送风方向的示意图如图4所示。
需要说明的是，最终送风轨迹在空间中为曲面，图4中所示意的最终送风轨迹为其对应的曲面在空间的投影曲线。
在本发明实施例中，遥控器检测第一位置坐标并将其发送给空调内机。空调内机根据第一位置坐标和预先获取的第二位置坐标，确定遥控器相对于空调内机的相对位置坐标。空调内机根据相对位置坐标，从送风轨迹集合中确定最终送风轨迹，并根据最终送风轨迹调整空调内机的送风方向，使空调内机的送风方向对准遥控器，不需要用户通过遥控器调整空调内机的摆叶和导板，节约用户调整送风方向的时间和提高用户的使用体验。
上述本发明实施例图1步骤S104涉及的确定最终送风轨迹的过程，每个送风轨迹对应一曲面方程，参见图5，示出了本发明实施例提供的确定最终送风轨迹的流程图，包括以下步骤：
步骤S501：针对预设的送风轨迹集合中的每一送风轨迹，空调内机根据相对位置坐标，确定送风轨迹的曲面方程对应的方程计算值。
由前述内容可知，每个送风轨迹对应一曲线方程，在具体实现步骤S501的过程中，针对送风轨迹集合中的每一送风轨迹，空调内机利用相对位置坐标，确定该送风轨迹的曲面方程对应的方程计算值，通过前述方式，得到每个送风轨迹的曲面方程对应的方程计算 值。
步骤S502：空调内机确定方程计算值小于阈值的送风轨迹的个数。
需要说明的是，预先设置阈值，当一送风轨迹的方程计算值小于阈值时，表示相对位置坐标在该送风轨迹的曲面的一定范围内。
可以理解的是，相对位置坐标可能在一个送风轨迹的曲面上或在一个送风轨迹的曲面的一定范围内，也可能在多个送风轨迹的曲面的一定范围内。
当出现相对位置坐标在多个送风轨迹的曲面的一定范围内时，需要从前述多个送风轨迹中选择一送风轨迹作为最终送风轨迹。
需要说明的是，相对位置坐标在送风轨迹的曲面上是指：利用相对位置坐标，计算该送风轨迹的曲面方程对应的方程计算值为0，即对于一送风轨迹，若利用相对位置坐标计算得到的方程计算值F(X，Y，Z)为0，则相对位置坐标在该送风轨迹的曲面上。
在具体实现步骤S502的过程中，空调内机确定得到每个送风轨迹的方程计算值后，确定方程计算值小于阈值的送风轨迹的个数。
步骤S503：若方程计算值小于阈值的送风轨迹的个数为1个，空调内机确定方程计算值小于阈值的送风轨迹为最终送风轨迹。
在具体实现步骤S503的过程中，若方程计算值小于阈值(此时方程计算值也可能等于0)的送风轨迹的个数为1个，则空调内机确定该送风轨迹为最终送风轨迹。
步骤S504：若方程计算值小于阈值的送风轨迹的个数大于1个，空调内机确定最小的方程计算值对应的送风轨迹为最终送风轨迹。
在具体实现步骤S504的过程中，若方程计算值小于阈值的送风轨迹的个数大于1个，空调内机从方程计算值小于阈值的所有送风轨迹中，确定最小的方程计算值对应的送风轨迹为最终送风轨迹。
比如：假设阈值为a，当F(X，Y，Z)小于a时，指示相对位置坐标在曲面的一定范围内，方程计算值小于阈值的送风轨迹有两个，分别为曲面F1(X，Y，Z)＝b和曲面F2(X，Y，Z)＝c，其中b和c均小于a，b和c为方程计算值。
也就是说，相对位置坐标在曲面F1(X，Y，Z)和曲面F2(X，Y，Z)的一定范围内，此时比较b和c的大小，若b小于c，则确定曲面F1(X，Y，Z)对应的送风轨迹为最终送风轨迹，若c小于b，则确定曲面F2(X，Y，Z)对应的送风轨迹为最终送风轨迹。
需要说明的是，若b＝c，空调内机根据预设送风方式送风(比如左右摆风)。
在本发明实施例中，空调内机根据相对位置坐标，确定每个送风轨迹的曲面方程对应的方程计算值。空调内机利用阈值和所有的方程计算值，从所有送风轨迹中确定最终送风轨迹，并根据最终送风轨迹调整空调内机的送风方向，以节约用户调整送风方向的时间和提高用户的使用体验。

在具体实现中，处理单元604具体用于：确定与最终送风轨迹对应的导板角度和摆叶角度，根据导板角度调整空调内机的导板，以及根据摆叶角度调整空调内机的摆叶。
在本发明实施例中，空调内机根据遥控器发送的第一位置坐标和预先获取的第二位置坐标，确定遥控器相对于空调内机的相对位置坐标。空调内机根据相对位置坐标，从送风轨迹集合中确定最终送风轨迹，并根据最终送风轨迹调整空调内机的送风方向，使空调内机的送风方向对准遥控器，不需要用户通过遥控器调整空调内机的摆叶和导板，节约用户调整送风方向的时间和提高用户的使用体验。
优选的，结合图6示出的内容，每个送风轨迹对应一曲面方程，第二确定单元603包括计算模块和确定模块，各个模块的执行原理如下。

优选的，结合图7示出的内容，检测单元701包括：处理模块、记录模块、第一确定模块和第二确定模块，各个模块的执行原理如下。
