具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请的描述中，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
本申请实施例提供一种电子设备。该电子设备例如具有防水功能，该电子设备可以是智能穿戴设备或手机，智能穿戴设备可以包括：智能手环或智能手表等。该电子设备包括具有多点触发功能的触摸屏，该触摸屏例如可以是电容式触摸屏，电容式触摸屏是利用人体的电流感应进行工作的。例如可以是一块四层复合玻璃屏，玻璃屏的内表面和夹层各涂有一层氧化铟锡(Indium tin oxide，简写为ITO)，最外层是一薄层矽土玻璃保护层，夹层ITO涂层作为工作面，四个角上引出四个电极，内层ITO为屏蔽层以保证良好的工作环境。当用户手指触摸在金属层上时，由于人体电场，用户和触摸屏表面形成以一个耦合电容，对于高频电流来说，电容是直接导体，于是手指从接触点吸走一个很小的电流。这个电流分从别触摸屏的四角上的电极中流出，并且流经这四个电极的电流与手指到四角的距离成正比，通过对这四个电流比例的精确计算，得出触摸点的位置。当电子设备浸水时，水对触摸屏的冲击产生的触发效应类似于人体皮肤对屏幕的触发效应，很容易点亮屏幕。
图1为本申请实施例提供的一种电子设备的结构示意图。如图1所示，电子设备10包括：触摸屏2、处理器101和超声波检测装置102，超声波检测装置102用于对电子设备所处环境进行超声波检测，并将超声波检测结果发送给处理器101。处理器101用于从超声波检测结果中提取超声波信号的描述特征。处理器101还用于：若根据超声波信号的描述特征和预先存储的参数表判断电子设备位于水中，则关闭电子设备的触摸屏的触摸响应功能。
对此，本申请实施例提供一种电子设备的浸水检测方法，图2为本申请实施例提供的一种浸水检测方法的流程示意图，图2所示的浸水检测方法用于图1所示的电子设备。如图2所示，该浸水检测方法包括如下步骤：
S101、超声波检测装置对电子设备所处环境进行超声波检测。
超声波是一种频率高于20000HZ的声波。图3为本申请实施例提供的超声波检测装置的结构示意图。如图3所示，超声波检测装置102包括：超声波发送单元11和超声波接收单元12，其中，超声波发送单元11和超声波接收单元12均与处理器101连 接。超声波发送单元11用于向电子设备所处环境中发射超声波信号，超声波接收单元12用于接收由超声波发射单元发出的经过直达或反射的超声波信号，并将接收到的超声波信号发送给处理器101，从而实现对电子设备所处环境的超声波检测。
举例来说，电子设备例如可以是智能手表，图4为本申请实施例提供的智能手表的结构示意图。如图4所示，智能手表1包括：触摸屏2、超声波发送单元11和超声波接收单元12，其中，超声波发送单元11例如可以是设置在电子设备上的扬声器或者换能器，超声波接收单元12例如可以是设置在电子设备上的麦克风，该麦克风和扬声器上例如还贴有防水膜。由此，可以复用电子设备的扬声器作为超声波发送单元，并将麦克风作为超声波接收单元，无需额外增加新的部件，便于生产。
图5为本申请实施例提供的智能手表的使用场景示意图。如图5所示，该超声波信号例如可以传播预设距离，当距离超声波发射位置超过该预设距离时，则不会接收到该超声波信号。举例来说，该智能手表的超声波发送单元11发送的超声波信号的传播距离大于超声波发送单元11和超声波接收单元12之间的直线距离，以使得超声波接收单元能够接收到该超声波信号，且该超声波信号的传播距离小于穿戴该智能手表的用户和其他穿戴该智能手表的用户之间的距离，因此，当不同用户穿戴该智能手表游泳时，多台该智能手表即使同时发送超声波信号，也不会相互干扰。其中，该预设距离D例如可以是20cm。
S102、处理器从超声波检测结果中提取超声波信号的描述特征，根据超声波信号的描述特征和预先存储的参数表确定电子设备位于水中。
超声波发送单元发送的超声波信号经过该电子设备所处环境之后，超声波信号的波形特征、频率以及幅值发生变化，超声波接收单元12能够接收经过电子设备所处环境的超声波信号，作为超声波检测结果。超声波接收单元12将该超声波检测结果发送给电子设备的处理器后，该电子设备的处理器能够从超声波检测结果中提取超声波信号的描述特征，提取超声波信号的描述特征例如可以包括：从接收到的超声波检测结果中获取其波形特征、频率值，以及幅值。

存储器103中还存储有参数表等，处理器101可以通过运行或执行存储在存储器103内的软件程序，以及调用存储在存储器103中的参数表，以确定电子设备所处环境。其中，参数表包括超声波信号的各描述特征与电子设备所处环境之间的对应关系，电子设备所处的一种环境例如可以对应一个或多个超声波信号的描述特征。当处理器101接收到超声波检测结果后，可以根据超声波检测结果中的一个或多个超声波信号的描述特征确定当前电子设备所处环境。
超声波信号的描述特征具体可以是：超声波波形、超声波频率以及超声波的幅值等，电子设备所处环境例如可以是：水中、空气中，以及其他环境，该电子设备所处环境例如可以表示为00，01，10，也可以为1，2，3，还可以为A，B，C等。该参数表的超声波信号描述特征与电子设备所处环境之间的对应关系可采用卷积神经网络的方式训练获得。首先，可以大量采集水中，空气以及其他场景中经过电子设备所处环境的超声波信号，并从超声波信号中提取描述特征，确定提取出的每个描述特征与设备所处环境之间的对应关系，接着通过卷积神经网络对描述特征和电子设备所处环境的对应关系进行卷积运算以建立模型，并提取模型中的相关参数建立该参数表。
S103、处理器关闭电子设备的触摸屏的触摸响应功能。
电子设备的触摸屏是利用人体的电流感应进行工作的，能够对用户的触发产生响应，水对触摸屏的冲击效果类似于用户的触碰。当电子设备的触摸屏的触摸响应功能处于开启状态时，电子设备的触摸屏会对用户的触摸或水流的冲击产生响应。当电子设备的触摸屏的触摸响应功能处于关闭状态时，电子设备的触摸屏不会对用户的触发或水流的冲击产生响应。正常情况下，电子设备，特别是手表或手环的触摸屏的触摸响应功能处于开启状态，当电子设备位于水中时，为了避免水流的冲击引起误操作，需要用户手动关闭。
本实施例中处理器101能够在确定该电子设备位于水中时，关闭电子设备的触摸屏的触摸响应功能。其中，关闭电子设备的触摸屏的触摸响应功能包括：处理器101控制电子设备的触摸屏中的传感器不进行数据采集，或者控制触摸屏在接收用户的触发或水流的冲击后将触发信息发送给处理器101，处理器101对用户的触发或水流的冲击不作响应，从而可以防止水对电子设备的触摸屏的误触发。
当然，为了避免该电子设备的主板进水，也可以关闭该电子设备。
本申请实施例提供的浸水检测方法，能够通过超声波检测确定电子设备所处环境，当电子设备在水中时，可以及时关闭电子设备的触摸屏的触摸响应功能，避免了水对电子设备的触摸屏的误触发，该过程无需人工操作，提高了用户体验。

用户穿戴该电子设备洗手、洗澡、游泳或者潜水时，该电子设备可能一段时间在水中，一段时间不在水中，当用户结束洗手、洗澡、游泳或者潜水时，可以选择停止对该电子设备所处环境进行超声波检测，为确保用户已经结束洗澡或者游泳，则检测用户不在水中的时间至少达到第一阈值，第一阈值例如可以是用户一个游泳动作或洗澡动作的周期。当检测用户不在水中的时间大于或等于该动作周期时，可以认为用户已经结束洗澡或者游泳，此时可以停止对该电子设备所处环境进行超声波检测。
上述根据超声波信号的描述特征和预先存储的参数表确定电子设备不在水中，则关闭超声波检测装置，还可以包括：根据超声波信号的描述特征和预先存储的参数表确定电子设备不在水中的时间达到第一阈值时，停止对所述电子设备所处环境进行超声波检测。
本申请实施例提供的浸水检测方法，通过超声波检测确定电子设备不在水中时，可以停止对电子设备所处环境进行超声波检测，能够解决超声波检测功耗过大的问题。
当用户结束洗手、洗澡、游泳或者潜水时，可重新开启电子设备的触摸屏的触摸响应功能。图6为本申请实施例提供的另一种浸水检测方法的流程示意图。如图6所述，关闭电子设备的触摸屏的触摸响应功能后，该浸水检测方法还包括：
S201、处理器控制超声波检测装置以预设时间间隔对电子设备所处的环境进行超声波检测。
预设时间间隔例如可以是1s，1min或其他值，本申请实施例对预设时间间隔的具体值不作限制，用户洗手、洗澡、游泳或者潜水所需时间不同，为及时检测到电子设备所处环境的改变情况，本领域技术人员可根据实际情况设置合适的时间间隔，这些均属于本申请的保护范围。
以预设时间间隔对电子设备所处的环境进行超声波检测，与一直进行超声波检测相比，能够降低超声波功耗。
S202、处理器从超声波检测结果中提取超声波信号的描述特征，根据超声波信号的描述特征和参数表，确定电子设备不在水中。
当超声波检测结果中提取的超声波信号的描述特征对应该参数表中空气中或其他环境时，可以确定电子设备不在水中，认为用户洗手、洗澡、游泳或者潜水结束。
S203、处理器开启电子设备的触摸屏的触摸响应功能。
确定电子设备不在水中时，可自动开启电子设备的触摸屏的触摸响应功能，不需要用户手动操作，提高了用户体验。
本申请实施例提供的浸水检测方法，能够在电子设备离开水之后自动开启电子设备的触摸屏的触摸响应功能，无需人工操作，提高了用户体验。
该浸水检测方法还包括：若根据超声波信号的描述特征和参数表，确定电子设备位于水中，则保持关闭电子设备的触摸屏的触摸响应功能的状态。
