拖地机器人100对房间的地面进行清洁，当拖地机器人100上的电池105的电量少于预设电量阈值时，如图8所示，拖地机器人100自动驶向基站200。拖地机器人100通过基站200上的入槽口205进入基站200，并停靠在基站200上的预设停靠位置。拖地机器人100停靠在基站200上的状态可参阅图9。
此时，拖地机器人100上的充电部件111和基站200上的供电部件接触，基站200从市电获取电力，并通过供电部件和充电部件111向拖地机器人100的电池105进行充电。拖地机器人100充满电后，驶离基站200，继续对房间地面进行清洁。
拖地机器人100可设置为对地面进行拖地清洁。拖地机器人100对房间地面拖地一段时间，拖擦件110变脏污后，拖地机器人100驶向基站200。拖地机器人100通过基站200上的入槽口205进入基站200，并停靠在基站200上的预设停靠位置。拖地机器人100停靠在基站200上的状态可参阅图9。此时，拖地机器人100的拖擦件110容置在清洗槽203上，在水泵209的作用下，基站200内的清水箱的清洁用水流向清洗槽203，通过清洗槽203上的进液结构喷向拖擦件110上，同时拖擦件110与清洁槽内的凸起的清洗肋2031刮擦，从而实现对拖擦件110的清洁。清洗拖擦件110后的脏污水从清洁槽上的排液结构流出清洗槽203，在水泵209的作用下，脏污水收集到污水箱。
应该理解，本申请实施例描述的基站200只是一个具体示例，并不对本申请实施例的基站200构成具体限定，本申请实施例的基站200还可以为其它的具体实现方式，例如，本申请实施例的基站200可以不包括水箱204，基站主体202可以连接自来水管和排水管，从而使用自来水管的自来水清洗拖地机器人100的拖擦件110，清洗拖擦件110后的脏污水由清洗槽203通过排水管流出基站200。或者，在其它的实现方式中，基站可以比图5所示的基站200有更多或更少的部件。
基于上述拖地机器人100以及基站200，本申请实施例提供了一种控制拖地机器人的方法，该方法应设置为拖地机器人，拖地机器人设有拖擦件，拖擦件设置为对地面进行拖地清洁。如图10所示，该方法包括：
步骤1001，若拖地机器人通过处于目标清洁程度的拖擦件拖擦了处于第一状态的第一区域，执行与清洗拖擦件相关的拖擦件清洗操作。
其中，拖擦件设置为拖擦地面，拖擦件的清洁程度表示拖擦件的拖擦地面的表面的干净程度。处于目标清洁程度的拖擦件为拖擦件的拖擦地面的表面处于一定的干净程度。例如，处于目标清洁程度的拖擦件是指已被清洗后或者未清洁过地面的拖擦件，即脏污程度 较低的拖擦件；处于第一状态是指被拖擦件拖擦了N遍，且N为自然数。可以看出，当N的取值为0时，处于第一状态的第一区域是地面上未被拖擦件拖擦过的区域；当N的取值为其他正整数(1、2、3……)时，处于第一状态的第一区域是地面上已被拖擦件拖擦过的区域。其中，拖地机器人的底部设置有拖擦件和驱动轮，当拖地机器人在驱动轮的驱动下进行移动时，拖擦件也相对地面发生滑动，从而实现对地面的拖擦清洁。其中，拖擦件的拖擦方式包括但不限于以下几种方式：
拖擦方式一：拖擦件直接固定于拖地机器人的底部，随拖地机器人的移动而移动，从而实现对地面的拖擦。可以看出，在拖擦方式一中，拖擦件的拖擦轨迹与拖地机器人的移动轨迹相同。
拖擦方式二：拖地机器人设置有转动轴，该转动轴可贯穿整个拖地机器人，或者位于拖地机器人的底部，拖擦件通过该转动轴间接固定于拖地机器人的底部。在拖地机器人的移动过程中，该转动轴可带动拖擦件发生旋转，旋转的拖擦件和地面产生滑动摩擦，从而实现对地面的拖擦，此时拖擦件的拖擦轨迹与拖地机器人的移动轨迹不同。
拖擦方式三：拖地机器人同时执行上述的拖擦方式一和拖擦方式二。例如，拖擦件安装到拖地机器人的转动轴上，拖地机器人一边在地面上移动，一边转动拖擦件，从而拖擦件即随着拖地机器人的移动而在地面上移动，也随着转动轴的驱动而进行转动。可选地，若拖地机器人通过处于目标清洁程度的拖擦件拖擦了处于第一状态的第一区域，执行与清洗拖擦件相关的拖擦件清洗操作，包括：若拖地机器人通过处于目标清洁程度的拖擦件拖擦处于第一状态的第一区域，调整拖擦件的拖擦数值，拖擦数值设置为表示拖擦件的脏污程度。若拖擦数值满足清洗条件，执行与清洗拖擦件相关的拖擦件清洗操作。当执行与清洗拖擦件相关的拖擦件清洗操作之后，调整拖擦件的拖擦数值，以使得拖擦数值表示的拖擦件的脏污程度减小。
其中，拖地机器人通过拖擦件对第一区域进行拖擦前，拖擦件处于目标清洁程度，即清洗后或者未清洁地面的状态，此时该处于目标清洁程度的拖擦件适设置为对地面进行清洁；当拖擦件开始对第一区域进行拖擦后，污渍由第一区域转移至拖擦件，因而拖擦件的状态发生改变，脏污程度变大；当拖擦件完成对第一区域的拖擦后，拖擦数值满足清洗条件，此时拖擦件的脏污程度已经不适于继续对地面进行清洁，需要对拖擦件进行清洗，因此可以触发拖地机器人执行与清洗拖擦件相关的拖擦件清洗操作。
进一步地，执行与清洗拖擦件相关的拖擦件清洗操作后，调整拖擦件的拖擦数值，以使得拖擦数值表示的拖擦件的脏污程度减小。其原因在于，拖擦件被清洗之后，拖擦件携带的污渍被清洗掉，则拖擦件的脏污程度减小，因此，需要对拖擦件的拖擦数值进行相应调整，使得调整后的拖擦数值不满足清洗条件，则拖擦件可以重新开始对地面进行清洁。
步骤1002，若拖地机器人通过处于目标清洁程度的拖擦件拖擦了处于第二状态的第二区域，执行与清洗拖擦件相关的拖擦件清洗操作。
其中，根据以上内容可以得知，处于目标清洁程度的拖擦件是指清洗后或者未清洁地面的拖擦件；另外，处于第二状态是指被拖擦件拖擦了N+1遍，N为自然数，且第一区域的面积小于第二区域的面积。其中，当第一区域与第二区域为不同目标区域时，满足第一区域与第二区域处于相同脏污程度，可以看出，无论N的取值为多少，处于第二状态的第二区域均为地面上已被拖擦件拖擦过的区域。与处于第一状态的第一区域相比，处于第二状态的第二区域被拖擦件拖擦的遍数更多，因此，处于第二状态的第二区域是比处于第一状态的第一区域脏污程度更小的区域。可选地，若拖地机器人通过处于目标清洁程度的拖擦件拖擦了处于第二状态的第二区域，执行与清洗拖擦件相关的拖擦件清洗操作，包括： 若拖地机器人通过处于目标清洁程度的拖擦件拖擦处于第二状态的第二区域，调整拖擦件的拖擦数值，拖擦数值设置为表示拖擦件的脏污程度。若拖擦数值满足清洗条件，执行与清洗拖擦件相关的拖擦件清洗操作。当执行与清洗拖擦件相关的拖擦件清洗操作之后，调整拖擦件的拖擦数值，以使得拖擦数值表示的拖擦件的脏污程度减小。
其中，将通过拖擦件拖擦处于第一状态的第一目标区域作为第一次拖擦，将通过拖擦件拖擦处于第二状态的第二区域作为第二次拖擦，由于第二次拖擦过程中拖擦件的拖擦方式与第一次拖擦过程中拖擦件的拖擦方式相同，因而此处不再对第二次拖擦过程中拖擦数值的调整加以赘述。接下来，对第一次拖擦和第二次拖擦进行分析说明：
对于同一拖擦件，该拖擦件在分别进行第一次拖擦和进行第二次拖擦之前，该拖擦件均为同一目标清洁程度，即两次拖擦过程中拖擦件的起始状态是相同的；相应地，该拖擦件在分别完成对第一次拖擦和第二次拖擦之后，均满足了同一清洗条件，即两次拖擦过程中拖擦件的最终状态也是相同的。可以看出，在两次拖擦过程中，第一区域与第二区域转移至拖擦件的污渍量是相同的。其中，虽然第二区域是比第一区域脏污程度更小的区域，即第二区域单位面积上的污渍量小于第一区域单位面积上的污渍量；但是，第二区域的面积大于第一区域的面积，因而第二区域的总污渍量可以与第一区域的总污渍量相同，以使得两次拖擦过程中转移至拖擦件的污渍量相同。也就是说，在拖擦件重复拖擦地面的过程中，后一次触发拖地机器人执行拖擦件清洗操作时的拖地面积，大于前一次触发拖地机器人执行拖擦件清洗操作时的拖地面积。
接下来，对第一次拖擦与第二次拖擦过程中，拖擦数值的调整方式进行说明。在本实施例中，通过拖擦数值来表示拖擦件的脏污程度，在拖擦件对地面的拖擦过程中，通过调整拖擦件的拖擦数值，来反映拖擦件的脏污程度变化，进而基于拖擦数值控制对拖擦件进行清洗。其中，拖擦件的拖擦过程可以看作是污渍由被拖擦件清洁的地面转移至拖擦件的过程，该过程中被拖擦件清洁的地面的脏污程度降低，拖擦件的脏污程度相应的升高。也就是说，拖擦件变脏是由被拖擦件清洁的地面引起的，因此，在一种可选的实施方式中，可以通过被拖擦件清洁的地面的脏污程度调整拖擦件的脏污程度。
在该实施方式中，将地面上被拖擦件清洁的区域作为目标区域，可用清洁数值来表示目标区域的脏污程度，其中，该目标区域为第一区域或者第二区域。则调整拖擦件的拖擦数值的步骤具体包括：确定目标区域的清洁数值，根据目标区域的清洁数值调整拖擦件的拖擦数值。
可选地，确定目标区域的清洁数值的方式包括但不限于如下几种：
1)预先向待清洁区域的区域地图配置目标区域的清洁数值，从而从区域地图中确定表示目标区域的目标地图区域后，可确定出配置给目标地图区域的清洁数值，以目标地图区域的清洁数值作为目标区域的清洁数值。
2)用户通过其他设备设定目标区域的清洁数值，拖地机器人可从这些设备直接获取目标区域的清洁数值。例如，用户通过智能手机输入待清洁区域的地面(包括目标区域)的清洁数值都为100。
3)拖地机器人根据待清洁区域的当前拖擦次数，确定待清洁区域的地面(包括目标区域)的清洁数值都为预设值。
可选地，为了能对具体的区域的脏污程度进行准确的分析，以提高对地面的清洁效率，可将清洁数值和区域地图进行结合，从而根据区域地图确定出具体的区域的清洁数值。此时，确定目标区域的清洁数值的步骤包括：获取待清洁区域的区域地图；在区域地图上定位出表示目标区域的目标地图区域；确定出配置给目标地图区域的清洁数值，以目标地图 区域的清洁数值作为目标区域的清洁数值。其中，区域地图设置为描述待清洁区域的信息，可选地，区域地图可以为栅格地图，栅格地图包括多个栅格，每个栅格均对应待清洁区域的一部分。例如，如图11所示，白色的栅格表示待清洁区域中拖擦件可以拖擦的区域，即，拖地机器人可通行的区域。黑色的栅格表示待清洁区域中拖擦件无法拖擦的区域，即障碍物区域。当然，本申请实施例不对待清洁区域的区域地图类型加以限定，也可以采用其他类型的区域地图(如特征地图、拓扑地图等区域地图)来描述待清洁区域的信息。其中，获取区域地图的方式包括但不限于：拖地机器人通过安装的激光雷达对待清洁区域进行探测，得到区域地图；拖地机器人沿待清洁区域的边缘移动，根据移动轨迹得到区域地图；用户通过终端将区域地图输入给拖地机器人；拖地机器人向服务器发起区域地图的获取指令，从而获取服务器返回的区域地图；拖地机器人通过安装的惯性测量单元(Inertial measurement unit，IMU)和碰撞传感器探测待清洁区域得到区域地图；拖地机器人通过安装的视觉传感器对待清洁区域进行感测，以获取区域地图等等。
进一步地，为了在获取区域地图后，能确定出配置给目标地图区域的清洁数值，可以通过如下的几种方式预先为区域地图配置清洁数值：
配置方式一，为区域地图配置默认的清洁数值。例如，在拖地机器人开始拖擦之前，为区域地图配置一参考清洁数值，如100。当区域地图为栅格地图时，可为每个栅格均配置该参考清洁数值，即默认每个栅格的脏污程度相同。
配置方式二，用户直接为区域地图配置清洁数值。例如，拖地机器人将获取的区域地图推送给终端，用户通过终端配置清洁数值。当区域地图为栅格地图时，用户可分别为每个栅格配置不同的清洁数值，也可以批量配置栅格的清洁数值。
配置方式三，拖地机器人按照参考方式为区域地图配置清洁数值。例如，拖地机器人通过图像传感器拍摄待清洁区域，得到待清洁区域图像，分析该待清洁区域图像得到待清洁区域的脏污程度，为区域地图配置待清洁区域的脏污程度对应的清洁数值。当区域地图为栅格地图时，拖地机器人可分别为每个栅格配置不同的清洁数值，也可以批量配置栅格的清洁数值。
获取待清洁区域的区域地图之后，在区域地图上定位出表示目标区域的目标地图区域。其中，目标区域是指地面上被拖擦件清洁的区域，而目标地图区域是目标区域在区域地图中对应的区域，也就是说，目标区域是地面上的实际区域，目标地图区域是区域地图中的虚拟区域。其中，在区域地图上定位出表示目标区域的目标地图区域的一种可选方式如步骤21和步骤22所示。
步骤21，获取拖地机器人在区域地图中的位置点。
获取拖地机器人在区域地图中的位置点，换言之，拖地机器人在区域地图中进行定位。获取拖地机器人在待清洁区域中的位置点，将该待清洁区域中的位置点映射到区域地图中，从而获取到拖地机器人在区域地图中的位置点。其中，待清洁区域的区域地图包括地图基准点，且该地图基准点与待清洁区域中的一个实际基准点相对应，即该实际基准点在区域地图中由地图基准点表示。该实际基准点可以为待清洁区域中的任一位置。进行获取时，首先通过定位装置获取拖地机器人在待清洁区域中的当前位置点，并计算该当前位置点与待清洁区域的实际基准点的位置关系信息(位置关系包括但不限于距离信息和方向信息)；
其次，将该位置关系信息映射到区域地图中，得到区域地图中的位置关系信息。例如，当位置关系信息包括距离信息和方向信息时，映射方式可以为将距离信息按照区域地图与待清洁区域之间的参考比例进行缩小或放大，得到区域地图中的距离信息，而将方向信息直接作为区域地图中的方向信息；
最后，以区域地图中的地图基准点为基准，根据区域地图中的位置关系信息获取拖地机器人在区域地图中的位置点，该位置点即为拖地机器人在区域地图中的当前位置点。例如，以区域地图为栅格地图为例，对获取拖地机器人在区域地图中的位置点的过程进行说明：
以栅格地图中的(0,0)位置为地图基准点，该(0,0)地图基准点对应待清洁区域中的实际基准点(x0，y0)。进行获取时，首先通过定位装置获取拖地机器人在待清洁区域中的当前位置点(x1，y1)，并计算(x1，y1)与(x0，y0)的位置关系信息；其次，将该位置关系信息映射到栅格地图中，假设栅格地图与待清洁区域之间的参考比例为A，则经过映射得到的栅格地图中的位置关系信息为[(x1-x0)/A，(y1-y0)/A]；最后，以(0,0)为基准点，获取拖地机器人在栅格地图中的位置点为[0+(x1-x0)/A，0+(y1-y0)/A]，该位置点即为拖地机器人在栅格地图中的当前位置点。
应该理解，步骤21还有其它的具体实现方式，例如，拖地机器人通过探测传感器(例如激光雷达、或者摄像头)探测出所在环境的特征，然后根据该所在环境的特征和区域地图表示的房间特征进行匹配，以实现拖地机器人在区域地图中的定位。或者，拖地机器人通过惯性传感器、或者卫星定位***进行定位等等。
步骤22，基于拖地机器人在区域地图中的位置点确定目标区域的目标地图区域。
获取拖地机器人在区域地图中的位置点后，可基于该位置点确定目标区域的目标地图区域。具体来说，因拖地机器人设置为定位的位置为固定位置，该设置为定位的位置和拖擦件的位置关系固定，从而可以利用设置为定位的位置和拖擦件的位置关系，基于该位置点确定目标区域的目标地图区域。
例如，当区域地图为栅格地图时，如图12所示，将位置点所在的栅格作为基准栅格，沿拖地机器人前进方向取3行栅格，沿垂直于拖地机器人前进方向在基准栅格左右各取3个栅格，即将3行7列共21个栅格作为目标区域的目标地图区域。需要说明的是，目标地图区域可以为一个或多个栅格。
根据上述内容可以得知，在获取待清洁区域的区域地图后，因为已经为区域地图配置了清洁数值，因而此时可直接确定区域地图中的目标地图区域的清洁数值，并将目标地图区域的清洁数值作为目标区域的清洁数值。
通过上述内容描述的方式，拖地机器人可确定出目标区域的清洁数值，然后，根据目标区域的清洁数值调整拖擦件的拖擦数值。其中，拖地机器人在对地面进行清洁的过程中，可以只调整拖擦件的拖擦数值；也可以既调整目标区域的清洁数值，也调整拖擦件的拖擦数值。
在需要对目标区域进行至少两次拖地清洁时，拖地机器人既调整目标区域的清洁数值，也根据目标区域的清洁数值调整拖擦件的拖擦数值。可以使得清洁数值能准确反映目标区域当前的脏污程度，从而根据目标区域的清洁数值调整的拖擦件的拖擦数值更为准确。为此，本申请实施例提供了如下的实现方式：
第一种实现方式：清洁数值表示目标区域是否被清洁，目标区域被清洁后的脏污程度小于未被清洁的脏污程度；相应地，拖擦数值表示拖擦件清洁的区域范围，拖擦件清洁的区域范围越大，拖擦件的脏污程度越高。确定目标区域的清洁数值之后，本实现方式的方法还包括：若目标区域被拖擦件清洁，将目标区域的清洁数值从未清洁标识调整为已清洁标识，从而实现调整目标区域的清洁数值。其中，未清洁标识表示目标区域还未被拖擦件清洁，已清洁标识表示目标区域已经被拖擦件清洁，本申请实施例不对未清洁标识和已清洁标识的表达方式进行限定。在一种可选的实施方式中，可以将两个不同的数字分别作为 未清洁标识和已清洁标识。例如，1作为未清洁标识，0作为已清洁标识。当然，也可以采用0作为未清洁标识，将1作为已清洁标识。该种方式下，根据目标区域的清洁数值调整拖擦件的拖擦数值，包括：根据目标区域调整后的清洁数值，更新拖擦件清洁的区域范围，以得到拖擦件的调整后的拖擦数值。
也就是说，当拖擦件完成对目标区域的清洁后，该目标区域的污渍转移至拖擦件，拖擦件清洁的区域范围中增加了该目标区域的区域范围，拖擦件的脏污程度升高。若目标区域被拖擦件清洁，则将目标区域的清洁数值从未清洁标识调整为已清洁标识；相应地，根据目标区域的清洁数值更新拖擦件清洁的区域范围，以得到拖擦件的调整后的拖擦数值。例如，在目标区域被拖擦件清洁之前，目标区域的清洁数值为1，即未清洁标识为1，在目标区域被拖擦件清洁之后，目标区域的清洁数值为0，即已清洁标识为0。若目标区域被拖擦件清洁，则将目标区域的清洁数值由1调整为0；相应地，将拖擦数值增加1，表示拖擦件清洁的区域范围中增加了该目标区域的区域范围。可以看出，拖擦数值越大，拖擦件清洁的区域范围越大，拖擦件的脏污程度越高。或者，在目标区域被拖擦件清洁之前，目标区域的清洁数值为0，即未清洁标识为0，在目标区域被拖擦件清洁之后，目标区域的清洁数值为1，即已清洁标识为1。若目标区域被拖擦件清洁，则将目标区域的清洁数值由0调整为1；相应地，将拖擦数值减小1，表示拖擦件清洁的区域范围中增加了该目标区域的区域范围，可以看出，拖擦数值越小，拖擦件清洁的区域范围越大，拖擦件的脏污程度越高。
第二种实现方式：清洁数值表示目标区域需要的清洁用时，需要的清洁用时越长，目标区域的脏污程度越高；相应地，拖擦数值表示拖擦件的清洁累计时间，清洁累计时间越长，拖擦件的脏污程度越高。本实现方式的方法包括：计算拖擦件对目标区域清洁的清洁时长。根据清洁时长调整目标区域当前需要的清洁用时，得到调整后的清洁用时，以调整后的清洁用时作为目标区域调整后的清洁数值，从而，实现了调整目标区域的清洁数值。该种方式下，根据目标区域的清洁数值调整拖擦件的拖擦数值，包括：若所述目标区域的清洁用时调整量不为零，根据所述清洁用时调整量调整所述拖擦件的拖擦数值，所述清洁用时调整量根据所述当前需要的清洁用时及所述调整后的清洁用时得到。其中，在拖擦件开始对目标区域进行清洁之前，目标区域的清洁数值为目标区域当前需要的清洁用时；以拖擦件开始对目标区域进行清洁的时间点为起点，计算拖擦件对目标区域的清洁时长，根据该清洁时长调整目标区域当前需要的清洁用时，得到调整后目标区域需要的清洁用时，以调整后目标区域需要的清洁用时作为目标区域调整后的清洁数值。
例如，在目标区域被清洁之前，目标区域当前需要的清洁用时(即目标区域的清洁数值)为10秒，则当拖擦件以6秒为清洁时长对目标区域进行清洁后，根据清洁时长(6秒)调整当前需要的清洁用时(10秒)，得到目标区域调整后的清洁用时为10秒-6秒＝4秒，将调整后的清洁用时(4秒)作为目标区域调整后的清洁数值，因此，将目标区域的清洁数值由10秒调整为4秒。
进一步地，若目标区域的清洁用时调整量不为零，根据清洁用时调整量调整拖擦件的拖擦数值，清洁用时调整量根据当前需要的清洁用时及所述调整后的清洁用时得到。其中，若目标区域的清洁用时调整量不为零，则说明目标区域上的污渍已经转移至拖擦件，使得拖擦件的脏污程度升高，若目标区域的清洁用时调整量为零，则目标区域上的污渍未转移至拖擦件，因而不能使拖擦件的脏污程度继续升高。因此，在目标区域的清洁用时调整量不为零的情况下，根据清洁用时调整量调整拖擦件的拖擦数值。例如，仍以目标区域当前需要的清洁用时为10秒，调整后的清洁用时为4秒为例，则清洁用时调整量为10秒-4秒 ＝6秒，由于6秒不为零，因此将拖擦数值增加6秒，表示拖擦件的清洁累计时间中增加了对目标区域的6秒的清洁时长，清洁累计时间增大，拖擦件的脏污程度升高。
第三种实现方式：清洁数值表示目标区域需要的清洁总次数，需要的清洁总次数越多，目标区域的脏污程度越高；相应地，拖擦数值表示拖擦件的清洁累计次数，清洁累计次数越多，拖擦件的脏污程度越高。本实现方式的方法还包括：计算拖擦件对目标区域清洁的已清洁次数。然后，根据已清洁次数调整目标区域当前需要的清洁总次数，得到调整后的清洁次数，以调整后的清洁次数作为目标区域调整后的清洁数值，从而，实现了调整目标区域的清洁数值。该种方式下，根据目标区域的清洁数值调整拖擦件的拖擦数值，包括：若所述目标区域的清洁次数调整量不为零，基于所述清洁次数调整量调整所述拖擦件的拖擦数值，所述清洁次数调整量根据所述当前需要的清洁总次数及所述调整后的清洁次数得到。其中，在拖擦件开始对目标区域进行清洁之前，目标区域的清洁数值为目标区域当前需要的清洁总次数；以拖擦件第一次对目标区域进行清洁开始计次，计算拖擦件对目标区域清洁的已清洁次数，根据已清洁次数调整目标区域当前需要的清洁总次数，得到调整后的清洁次数，以调整后的清洁次数作为目标区域调整后的清洁数值。
例如，在目标区域被清洁之前，目标区域当前需要的清洁总次数(即目标区域的清洁数值)为10次，则当拖擦件以6次为已清洁次数对目标区域进行清洁后，根据已清洁次数(6次)调整当前需要的清洁总次数(10次)，得到调整后的清洁次数为10次-6次＝4次，将调整后的清洁用时(4次)作为目标区域调整后的清洁数值，因此，将目标区域的清洁数值由10次调整为4次。
进一步地，若目标区域的清洁用时调整量不为零，基于所述清洁次数调整量调整所述拖擦件的拖擦数值，所述清洁次数调整量根据所述当前需要的清洁总次数及所述调整后的清洁次数得到。其中，若目标区域的清洁次数调整量不为零，则说明目标区域上的污渍已经转移至拖擦件，使得拖擦件的脏污程度升高，若目标区域的清洁次数调整量为零，则目标区域上的污渍未转移至拖擦件，因而不能使拖擦件的脏污程度继续升高。因此，在目标区域的清洁次数调整量不为零的情况下，根据清洁次数调整量调整拖擦件的拖擦数值。例如，仍以目标区域当前需要的清洁总次数为10次，调整后的清洁次数为4次为例，则清洁次数调整量为10次-4次＝6次，由于6次不为零，因此将拖擦数值增加6次，表示拖擦件的清洁累计时间中增加了对目标区域的6次的清洁次数，清洁累计次数增大，拖擦件的脏污程度升高。
可选地，本申请实施例提供的方法在确定目标区域的清洁数值之后，还包括：确定目标区域的清洁数值的调整量。相应的，根据所述目标区域的清洁数值调整所述拖擦件的拖擦数值，包括：根据所述目标区域的清洁数值的调整量调整所述拖擦件的拖擦数值。
可选地，在本实施例中，对于目标区域的清洁数值的调整量的确定方式，可以根据清洁累计信息将目标区域的清洁数值由第一清洁数值调整为第二清洁数值，并将第一清洁数值与第二清洁数值的差值确定为目标区域的调整量，从而实现目标区域的清洁数值的调整量的确定。可以看出，第一清洁数值是目标区域被清洁之前的清洁数值，第二清洁数值是目标区域被清洁之后的清洁数值。在清洁数值越大表示脏污程度越高的情况下，第一清洁数值大于第二清洁数值，调整量为清洁数值的减小量，根据目标区域的清洁数值的调整量调整拖擦件的拖擦数值的实现方式为：将拖擦件的拖擦数值增加一增加量，增加量等于目标区域的清洁数值的调整量。
进一步地，清洁累计信息为总清洁时间或者当前清洁次数中的一种。接下来，以第一清洁数值大于第二清洁数值为例，对上述两种情况分别进行详细说明：
清洁累计信息为总清洁时间：其中，总清洁时间是指拖擦件对目标区域的累计清洁时间，累计清洁时间越长，目标区域的脏污程度越低，拖擦件的脏污程度越高；相应地，第一清洁数值是目标区域被清洁之前的清洁数值，第二清洁数值是目标区域到达累计清洁时间之后的清洁数值，目标区域的清洁数值随累计清洁时间的增大而减小。进一步地，目标区域的清洁数值和累计清洁时间可以为以下三种关系中的任意一种：清洁数值和累计清洁时间呈线性递减关系：例如，清洁数值和累计清洁时间的关系式为：V＝V0-KT；其中，V为第二清洁数值，V0为第一清洁数值，T为累计清洁时间，K为常数。
可以看出，清洁数值随清洁累计时间的增加而均匀减小，清洁数值的减小量(即调整量)不随累计清洁时间的增加而变化。清洁数值和累计清洁时间呈指数递减关系：例如，清洁数值和累计清洁时间的关系式为：V＝V0/[e^(KT)]；其中，V为第二清洁数值，V0为第一清洁数值，e为自然常数(e值约为2.718)，T为累计清洁时间，K为常数。
如图13所示，可以看出，随着累计清洁时间的增加，清洁数值的减小量(即调整量)逐渐变小；相应地，如图14所示，累计清洁时间越长，由目标区域转移到拖擦数值上的脏污量越小，拖擦数值的增加速度逐渐变缓。在实际应用中，地面的污渍主要是在拖擦的前期转移到拖擦件上，随着累计清洁时间的增加，转移到拖擦件上的脏污量也越来越小，因此清洁数值和累计清洁时间呈指数递减关系的情况与实际情况较为相符。
清洁数值的调整量和累计清洁时间呈反比关系：在第一清洁数值大于第二清洁数值的情况下，清洁数值的调整量即为清洁数值的减小量。由于清洁数值的调整量和累计清洁时间呈反比关系，因而随着累计清洁时间的增长，在相同的清洁时间内，清洁数值的减小量逐渐变小。可以看出，该情况是与清洁数值和累计清洁时间呈指数递减关系相似的一种情况，均与实际情况较为相符。
清洁累计信息为当前清洁次数：其中，当前清洁次数是指拖擦件对目标区域的累计清洁次数，累计清洁次数越多，目标区域的脏污程度越低，拖擦件的脏污程度越高；相应地，第一清洁数值是目标区域被清洁之前的清洁数值，第二清洁数值是目标区域到达累计清洁次数之后的清洁数值，目标区域的清洁数值随累计清洁次数的增大而减小。
需要说明的是，目标区域的清洁数值和累计清洁次数同样可以为以下三种关系中的任意一种：清洁数值与累计清洁次数呈线性递减关系、清洁数值与累计清洁次数呈指数递减关系、清洁数值的调整量与累计清洁次数呈反比关系，且后两种关系与实际情况较为相符。由于原理与清洁累计信息为累计清洁时间中的原理相同，因而此处不再加以赘述。
可选地，当清洁数值越小标识脏污程度越高的情况下，第一清洁数值小于第二清洁数值，调整量为清洁数值的增大量，根据目标区域的清洁数值的调整量调整拖擦件的拖擦数值的实现方式为，将拖擦件的拖擦数值减小一减小量，减小量等于目标区域的清洁数值的调整量。基于以上任一可选实施例完成对拖擦件的拖擦数值的调整之后，若拖擦数值满足清洗条件，则表示拖擦件的脏污程度已经不适于继续对地面进行清洁，需要对拖擦件进行清洗，因此可以触发拖地机器人执行与清洗拖擦件相关的拖擦件清洗操作。
其中，拖擦数值满足清洗条件包括拖擦数值到达拖擦阀值，则在拖擦件的拖擦数值到达参考的拖擦阀值之后，可执行相关的拖擦件清洗操作。需要说明的是，当拖擦数值的表示方式不同时，拖擦阀值的数值及单位也有所不同。例如，当拖擦数值表示拖擦件的清洁累计时间的时候，拖擦阀值为清洁时间阀值，如1000秒，则当拖擦件的清洁累计时间到达1000秒时，执行相关的拖擦件清洗操作；当拖擦数值表示拖擦件的清洁累计次数的时候，拖擦阀值为清洁次数阀值，如500次，则当拖擦件的清洁累计次数到达500次时，执行相关的拖擦件清洗操作。
在一种可选的实施方式中，执行与清洗拖擦件相关的拖擦件清洗操作，包括：控制拖地机器人移动至基站，以通过该基站对拖地机器人的拖擦件进行清洗。如图8所示，基站对拖擦件的清洗方式可以为，拖地机器人移动到基站内，以使拖地机器人底部的拖擦件位于基站的清洗槽上，清洗槽向拖擦件喷射清洗液，同时，控制拖擦件和清洗槽的凸肋滑动摩擦，从而实现对拖擦件的清洗。
应该理解，与清洗拖擦件相关的拖擦件清洗操作除了上述的控制拖地机器人移动至基站，以通过该基站对拖地机器人的拖擦件进行清洗之外，拖擦件清洗操作还可以是其它的实现方式，例如，拖地机器人提示用户更换拖擦件，如通过拖地机器人上的扬声器发出提示音频，或者通过拖地机器人上的指示灯发出提示灯信号、或者向终端发送提示信息，以使得该终端提示用户更换拖擦件。这样，用户可对更换的拖擦件进行清洗。再如，拖擦件清洗操作还可以为拖地机器人移动到基站，在基站上自动将脏污的拖擦件更换为清洁的拖擦件，其中，脏污的拖擦件在基站上自动进行清洗，或者由用户进行清洗。
可选地，本实施例提供的控制拖地机器人的方法还包括：在拖地机器人从地面的第一位置移动至第二位置以对地面进行拖地清洁之前，预估拖地机器人从第一位置移动至第二位置的移动轨迹；基于该移动轨迹预测拖地机器人从第一位置移动至第二位置的过程中，拖擦件的拖擦数值是否满足清洗条件。
其中，第一位置、第二位置均为待清洁区域中的实际位置，可选地，预估拖地机器人从第一位置移动至第二位置的移动轨迹的方式可以为：在第一位置与第二位置之间不存在障碍物的情况下，拖地机器人从第一位置移动至第二位置的移动轨迹为由第一位置指向第二位置的直线轨迹；在第一位置与第二位置之间存在障碍物的情况下，拖地机器人需要绕开障碍物，并选择非直线的参考轨迹作为从第一位置移动至第二位置的移动轨迹。
在预估移动轨迹之后，进一步预测拖擦件沿该移动轨迹移动的过程中拖擦数值的变化量，拖擦数值的变化量是该移动过程中经过的所有目标区域的清洁数值的变化量之和；若拖擦件当前的拖擦数值与预测的移动过程中拖擦数值的变化量之和满足清洗条件，则说明拖地机器人由第一位置移动到第二位置的过程中，拖擦件的拖擦数值会在移动中途的一点满足清洗条件，则拖擦件仅在到达该点之前适设置为对地面进行清洁，在到达该点之后，由于拖擦件的拖擦数值已满足清洗条件，因而拖擦件不适合继续清洁由该点至第二位置之间的目标区域。
对此，本实施例在预测结果为拖地机器人从第一位置移动到第二位置的过程中，拖擦件的拖擦数值满足清洗条件的情况下，控制拖地机器人从第一位置向基站移动，以使基站清洗拖擦件，从而避免了拖擦件在移动中途满足清洗条件，保证了拖擦件的拖擦效果。进一步地，在拖擦件被基站清洗之后，控制拖地机器人由基站所在的位置移动至第二位置，以保证对拖地机器人的清洗不会影响到后续的清洁过程。
综上所述，本申请实施例在拖擦件重复拖擦地面的过程中，后一次控制拖地机器人执行拖擦件清洗操作时的拖地面积，大于前一次控制拖地机器人执行拖擦件清洗操作时的拖地面积。
进一步地，通过调整拖擦件的拖擦数值，而拖擦数值表示的是拖擦件的脏污程度，则在拖擦数值满足清洗条件的情况下控制拖地机器人执行拖擦件的清洗操作，实现了基于拖擦件的脏污程度来控制拖擦件的清洗，因此，该种控制方式更为智能和灵活，从而能够对拖擦件进行及时清洗，进而保证了地面的清洁效果。另外，根据清洁数值调整拖擦件的拖擦数值，符合污渍由地面转移至拖擦件的实际清洁过程；并且，清洁数值的确定方式有多种，灵活性较高，适用范围广。
