Description

饮用水供给装置的出水控制方法和系统 技术领域
本发明涉及自动化控制技术领域，特别是涉及一种饮用水供给装置的出水控制方法和系统。
背景技术
饮水机、净水机等都是日常生活中经常被用到的饮用水供给装置，一般的饮用水供给装置均设有出水口，在出水口处设置出水开关，该出水开关为机械装置。在取水时，使用者需要用手动控制该出水开关，先打开出水开关，等水灌注到一定高度后再关闭出水开关。这种使用方式由于需要使用者弯腰躬在饮水机、净水机等前等待水装满，很不方便，而且，当取热水时，容易因开水溅出对人身造成伤害，存在安全隐患。
目前，有些饮用水供给装置也有定容积的饮水冲注装置，即规定配合某种容积固定的水杯使用，饮水机靠内部定容积的容器定量自动将其灌满。这种饮水机只能针对固定大小的盛水容器(如水杯、水壶)完成灌注，无法自动完成将各种大小不一、容积不定的盛水容器的灌注任务，使其应用受到限制。
发明内容
本发明的目的在于克服现有技术的缺点和不足，提供一种便于使用且能够适用于各种容积不定的盛水容器的饮用水供给装置的出水控制方法和系统。
本发明的目的通过如下技术方案实现：

若是，则根据所述回波信号以及所述距离确定所述盛水容器的容器沿高度；
根据所述回波信号以及所述距离确定所述盛水容器中的水面高度；
根据所述容器沿高度、所述水面高度控制所述饮用水供给装置的出水。
一种饮用水供给装置的出水控制系统，其包括：

具体实施方式
为使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步的详细说明。应当理解，此处所描述的具体实施方式仅仅用以解释本发明，并不限定本发明的保护范围。
在下述说明中，首先针对饮用水供给装置的出水控制方法的实施例进行说明，再对本发明的饮用水供给装置的出水控制系统的各实施例进行说明。
实施例一
参见图1所示，为本发明的饮用水供给装置的出水控制方法的实施例一的流程示意图。如图1所示，本实施例中的饮用水供给装置的出水控制方法包括如下步骤：
步骤S101：获取超声波传感器检测的回波信号，其中，所述超声波传感器设置在饮用水供给装置出水口处；
超声波传感器的个数可以根据实际需要选取，为了实现对出水的自动控制，一般需要至少两个超声波传感器，为此，在其中一个实施例中，所述超声波传感器的个数至少包括两个，其中，一个超声波传感器用于发射超声波，至少一个超声波传感器用于接收超声波，也就是说，可以是一个超声波传感器用于发射超声波，一个或者多个超声波传感器用于接收超声波，可以通过一个超声波传感器发射强度较强的超声波，回波信号为该超声波信号经搁板、盛水容器或者水面等反射后信号，回波信号通过用于接收超声波的超声波传感器检测，但需要说明的是，并不限于至少两个超声波传感器；
步骤S102：根据所述回波信号以及预先存储的所述超声波传感器与所述饮用水供给装置的搁板之间的距离，判断是否有盛水容器置于所述出水口与所述搁板之间，若是，则进入步骤S103；
其中，盛水容器置于所述出水口与搁板之间一般是指盛水容器置放置于所述搁板上，当然也可以是盛水容器悬于所述盛水容器置之上，例如，使用者用 手拿着杯子；
当超声波的传播距离不同时，传播时间也是不同的，因此，可以根据超声波传感器与搁板之间的距离确定超声波在超声波传感器与搁板之间传播所需的第一传播时间，而若所述出水口与所述搁板之间放置了盛水容器，传播距离减小，传播时间也相应的减小，同时超声波在传播时遇到盛水容器沿时，会有较多的能量被反射，因此，容器沿反射的回波信号的强度也较强，因而，若所述回波信号在小于所述第一传播时间的某一时间点(或某一时间范围内)有强度的突变(一般是指突然增大)，则可以判定为有盛水容器置于所述出水口与所述搁板之间；
如图2所示，为某次检测时，无盛水容器的回波信号的波形图2(a)和有盛水容器的回波信号的波形图2(b)，通过图2(a)可知，回波信号在M点之后强度明显增强，可以确定第一传播时间为1.15ms，而通过图2(b)可知，在M点之前，超声波的回波信号强度出现突变，也证明了本发明的根据所述回波信号以及所述距离判断是否有盛水容器置于所述出水口与所述搁板之间的方式是可行的；
步骤S103：根据所述回波信号以及所述距离确定所述盛水容器的容器沿高度；
首先根据所述回波信号确定容器沿对应的第二传播时间，即超声波从超声波传感器传播到所述容器沿的所需的时间，如图2(b)所示，回波波形是在一个时间范围内发生强度的突变，可以先确定该时间范围的起始时间和终止时间，例如，通过强度比较的方式进行确定，在确定该时间范围的起始时间和终止时间之后，就可以将终止时间与起始时间求差再除以二得到第二传播时间，即T2＝(Tf-Ts)/2，其中，T2表示第二传播时间，Ts表示起始时间，Tf表示终止时间，也可以根据该时间范围内回波信号的最大值对应的时间确定为第二传播时间；
在确定第二传播时间之后，再根据第二传播时间以及所述距离确定所述盛水容器的容器沿高度，可以根据h1＝H-V T2确定所述盛水容器的容器沿时间高度，其中，h1表示容器沿高度，H表示超声波传感器到隔板的高度，V表示超声波的传播速度；
步骤S104：根据所述回波信号确定所述盛水容器中的水的水面高度；
首先，根据所述回波信号确定所述盛水容器中的水对应的第三传播时间，即为超声波从超声波传感器传播到所述盛水容器中的水面的所需的时间，如图2(b)所示，回波信号在第二传播时间之后有一个持续的强度增强，这一部分是由于超声波在水面发生发射，且在水面上超声波被较多的反射而形成的，因此，可以先确定这一部分对应的起始时间和终止时间，则也可以将对应的终止时间与起始时间求差再除以二得到第三传播时间；
再根据第三传播时间以及所述距离确定水面高度，可以根据h2＝H-V T3确定水面高度，其中，h2表示水面高度，T3表示第三传播时间；
步骤S105：根据所述容器沿高度、所述水面高度控制所述饮用水供给装置的出水；
可以在水面高度与容器沿高度的比值小于预设值时给盛水容器加水，在水面高度与容器沿高度的比值达到预设值时，停止加水，也可以设置不同的提示参考值，例如60％、80％、90％，在水面高度与容器沿高度的比值达到某一参考值时，提示用户，如可以通过LED灯的闪烁进行提示，在检测到所述盛水容器已从所述出水口与搁板之间移开时，停止加水，检测所述盛水容器是否已从所述出水口与搁板之间移开方式与判断是否有盛水容器置于所述出水口与搁板之间相类似，即若没有第一传播时间之前的强度突变，则可以判定为所述盛水容器是否已从所述出水口与搁板之间移开，或者在判断是否有盛水容器置于所述出水口与所述搁板之间的判定结果为否时，停止加水，在此不予赘述。
需要说明的时，在加水过程中，上述几个步骤一般是不断重复进行的，这是考虑到，在加水过程中，水面高度是不断变化的，且使用者可能随时会移开盛水容器。
据此，依据上述本实施例中的方案，其是获取超声波传感器检测的回波信号，其中，所述超声波传感器设置在饮用水供给装置出水口处，基于该回波信号以及预先存储的所述超声波传感器与所述饮用水供给装置的搁板之间的距离，判断是否有盛水容器置于所述出水口与搁板之间，若是，则根据所述回波信号以及所述距离确定所述盛水容器的容器沿高度，并根据所述回波信号以及 所述距离确定所述盛水容器中的水面高度，则可以根据所述容器沿高度、所述水面高度控制所述饮用水供给装置的出水，实现了自动控制出水，即有盛水容器置于所述出水口与搁板之间时开始加水，盛水容器移开或者加满时停止加水，使用方便，能够适用于各种容积不定的盛水容器。
实施例二
由于仅需要水面高度与容器沿高度的实现对所述饮用水供给装置的出水的控制，即超声波的传播速度是定值，所以也可以通过传播时间表征上述水面高度与容器沿高度，相应的，超声波传感器与所述饮用水供给装置的搁板之间的距离也通过传播时间表征，而采集到的回波信号又是传播时间和强度的对应关系，可以大大简化计算过程，为此，在其中一个实施例中，可以用超声波从超声波传感器传播到所述搁板的第一传播时间代替所述距离，可以用所述第一传播时间与第二传播时间的第一差值代替容器沿高度，其中，第二传播时间为超声波从超声波传感器传播到所述容器沿的时间，可以用所述第一传播时间与第三传播时间的第二差值代替容器沿高度，其中，第三传播时间为超声波从超声波传感器传播到所述盛水容器中的水面的时间，以下具体阐述该实施例中的实现方式。
参见图3所示，为本发明的饮用水供给装置的出水控制方法的实施例二的流程示意图。如图3所示，本实施例中的饮用水供给装置的出水控制方法包括如下步骤：
步骤201：获取超声波传感器检测的回波信号，其中，所述超声波传感器设置在饮用水供给装置出水口处；
步骤202：根据所述回波信号以及预先存储的第一传播时间，判断是否有盛水容器置于所述出水口与所述饮用水供给装置的搁板之间，其中，第一传播时间指超声波从超声波传感器传播到所述搁板所需的时间，若是，则进入步骤S203；
步骤203：根据所述回波信号以及所述第一传播时间确定第一传播时间与第二传播时间的第一差值，其中，第二传播时间为超声波从超声波传感器传播到所述容器沿的时间；
在本步骤中，首先根据所述回波信号确定第二传播时间，再用第一传播时间减去第二传播时间得到第一差值；
步骤204：根据所述回波信号以及所述第一传播时间确定所述第一传播时间与第三传播时间的第二差值，其中，第三传播时间为超声波从超声波传感器传播到所述盛水容器中的水面的时间；
在本步骤中，首先根据所述回波信号确定第三传播时间，再用第一传播时间减去第三传播时间得到第二差值；
步骤205：根据所述第一时间差值、所述第二时间差值控制所述饮用水供给装置的出水。
可以在第二时间差值与第一时间差值的比值达到预设值时，停止加水，也可以设置不同的提示参考值，例如60％、80％、90％，在第二时间差值与第一时间差值的比值达到某一参考值时，提示用户，在检测到所述盛水容器已从所述出水口与搁板之间移开时，停止加水；
本实施例中其他技术特征与上述实施例中相同，在此不予赘述。
实施例三
考虑到容器沿的厚度往往比较小，超声波在容器沿反射的信号很弱，为了确定测量的准确性，可以在根据所述回波信号以及所述距离确定所述盛水容器的容器沿高度时，先将回波信号以较大的放大系数进行放大，再根据放大后的回波信号确定盛水容器的容器沿高度；为此，在本实施中，在不同的处理阶段，对回波信号进行不同的放大倍数的放大。
参见图4所示，为本发明的饮用水供给装置的出水控制方法的实施例三的流程示意图。如图4所示，本实施例中的饮用水供给装置的出水控制方法包括如下步骤：
步骤S301：获取超声波传感器检测的回波信号，其中，所述超声波传感器设置在饮用水供给装置出水口处；
步骤S302：按照第一放大系数对所述回波信号进行放大得到第一放大信号，根据所述第一放大信号以及预先存储的所述超声波传感器与所述饮用水供给装置的搁板之间的距离，判断是否有盛水容器置于所述出水口与搁板之间，若是， 进入步骤S303；
步骤S303：根据所述第一放大信号以及所述距离确定所述盛水容器的容器沿高度；
步骤S304：按照第二放大系数对所述回波信号进行放大得到第二放大信号，根据所述第二放大信号以及所述距离确定所述盛水容器中的水面高度；
步骤S305：根据所述容器沿高度、所述水面高度控制所述饮用水供给装置的出水；
其中，所述第一放大系数大于所述第二放大系数。
本实施例中其他技术特征与上述实施例一中相同，在此不予赘述。
实施例四
此外，上述的超声波传感器与搁板之间的距离可以根据实际设计需要进行设定，例如，若饮水机的设计尺寸是已经确定的，则超声波传感器与搁板之间的距离可以直接根据设计尺寸得到，或者通过测量得到；
但为了满足不同的产品需要，还可以增加检测超声波传感器与搁板之间的距离步骤。
参见图5所示，为本发明的饮用水供给装置的出水控制方法的实施例四的流程示意图。如图5所示，本实施例中的饮用水供给装置的出水控制方法包括如下步骤：
步骤S401：通过所述超声波传感器检测所述超声波传感器与所述搁板之间的距离，并对检测到的距离进行存储；
可以通过超声波传感器检测回波信号，根据回波信号确定第一传播时间，第一传播时间乘以超声波的传播速度就可以得到超声波传感器与搁板之间的距离；
步骤S402：获取超声波传感器检测的回波信号，其中，所述超声波传感器设置在饮用水供给装置出水口处；
步骤S403：根据所述回波信号以及预先存储的所述超声波传感器与所述饮用水供给装置的搁板之间的距离，判断是否有盛水容器置于所述出水口与所述搁板之间，若是，进入步骤S404；
步骤S404：根据所述回波信号以及所述距离确定所述盛水容器的容器沿高度；
步骤S405：根据所述回波信号确定所述盛水容器中的水的水面高度；
步骤S406：根据所述容器沿高度、所述水面高度控制所述饮用水供给装置的出水。
本实施例中其他技术特征与上述实施例中相同，在此不予赘述。
需要说明的是，上述实施例三、实施例四中的距离可以用第一传播时间代替，容器沿高度也可以用第一差值代替，水面高度也可以用第二差值代，在此不予赘述。
