随着智能家居技术的发展，家用电能的智能化程度日益增高。相应的，智能家居技术提供的用户和对应的家电之间的交互手段，应当符合人类习惯的控制方式。人类习惯的控制方式包括语言控制、手势控制或动作控制等简单的方式。针对上述人类习惯的控制方式，家电的生产厂商对家电进行了升级改造。生产厂商通过为家电添加麦克风或者摄像头，以增加家电采集用户的语音或者手势的功能，从而实现家电快速获取用户的控制指令的效果。然而，当家庭中设置有多个含有麦克风的家电之后，当用户通过语音控制家电时，存在家电产生误响应。也即，有可能多个设备同时听到用户的开机指令，而其中存在误操作的情况。另外，针对家电而言，由于需要时刻采集语音信号或者采集视频，造成的待机电能浪费也较为严重。
相应的，传统的使用遥控器控制家电的方法的功耗较少且不会产生误操作。但是每个家电需要对应的实体遥控器，用户在使用的时候总是需要先找到实体的遥控器，然后再通过该遥控器控制家电，使用方式不符合人类自然的习惯，造成控制家电的效率较低。
基于上述家电控制难题，本申请实施例提供一种家电智能化控制的方案，能够在不改造现有的移动终端以及家电的构造的前提下，实现移动终端对家电的便捷控制，实现低成本下快捷控制家电的效果。

在终端保护壳120套接在终端110之后，用户使用终端110时，终端保护壳120始终 保持与终端110的套接状态。由于物理空间上两者贴附在一起，因此两者可以被视作一个整体使用。
可选地，在本申请实施例中，终端保护壳120能够通过电性连接线与终端110连接在一起，从而使得终端保护壳120中的电性元件与终端110中电子元件组成为一个整体，实现相应的功能。

可选的，终端保护壳120还可以包括设置在外表面的指示灯。一种可能的方式中，该指示灯能够发出m种彩色的光线，m为正整数。该指示灯通过连接组件从终端获取电能发光。一种可能的方式中，指示灯能够发出的彩色光线包括红色、绿色、黄色、蓝色、白色、紫色和橙色。本申请不对指示灯具体能够发出的彩色的数量进行限定。
在终端保护壳120套接在终端上后，指示灯保持长灭状态。当终端保护壳120感知到通讯标签后，终端保护壳120能够发出彩色的光线。一种可能的方式中，终端保护壳120的指示灯发出的光线的颜色与通讯标签的外壳的颜色相同。在另一种可能的方式中，若指示灯仅能发出单色的光线，则指示灯通过点亮，表示终端保护壳120已感知到通讯标签。
除了图2介绍的终端110和终端保护壳120之外，定向系统100中还包括贴附有通讯标签130的被控对象140。
需要说明的是，被控对象140可以是具备指定功能的家电或者物联网(IoT，Internet of Things)设备。

可选地，通讯标签130的工作状态包括睡眠状态和唤醒状态。当通讯标签130处于唤醒状态时，通讯标签用于向外广播通讯标签的标签标识。当通讯标签130处于睡眠状态时，通讯标签以低于第一阈值的功耗运行。示意性的，第一阈值可以是20毫瓦、50毫瓦或100毫瓦等数值的功率值，本申请实施例对此不作限定。示意性的，通讯标签可以通过数据帧的形式向外广播标签标识。

请参见图5，图5是基于图1所示实施例提供的另一种通讯标签和被控对象之间的关系示意图。其中，在未挂靠阶段5A中，通讯标签130和被控对象140是互相独立的物理实体。在挂靠阶段5B中，通讯标签130被通过物理挂钩或者其它方式与被控对象140放置在一起。
通过上述图2至图5的介绍可以知道，终端和被控对象均是可以独立工作的电子设备。终端可以套接终端保护壳，同时被控对象可以贴附通讯标签，从而构成图1所示的定位系统。
请参见图6，图6是本申请实施例提供的一种定位系统实现定位的流程图。该定位系统可以通过图6所示的流程实现定位操作。图6所示步骤详细介绍如下。
步骤610，响应于通讯标签处于唤醒状态，通讯标签用于向外广播通讯标签的标签标识。
在本例中，通讯标签具有唤醒状态和睡眠状态两种状态。通讯标签将在处于唤醒状态时，向外广播自身的标签标识。示意性的，通讯标签的标签标识可以是指定的字符串。例如，通讯标签的标签标识可以是UWB123456abc，该字符串将被通讯标签在UWB指定的信道中进行广播。
在实际应用过程中，通讯标签周期性进行工作。在通讯标签的一个工作周期内，该工作周期分为唤醒状态和睡眠状态。例如，10秒钟为一个而工作周期，唤醒状态持续1秒钟，睡眠状态持续9秒钟。通讯标签将在唤醒状态时，向周围广播自身的标签标识。若通讯标签的标签标识是UWB123456abc，则通讯标签在UWB指定的信道中向周围广播字符串UWB123456abc。
步骤620，终端保护壳处于唤醒状态时，通过超宽带天线接收超宽带信道中的标签标识。
在本例中，当终端保护壳处于唤醒状态时，该终端保护壳通过内置的超宽带天线接收信道中的标签标识。
步骤630，终端保护壳将标签标识通过连接组件发送至终端中，以令终端与被控对象建立短距离通信连接或获取被控对象的空间方位信息。
在终端保护壳接收到标签标识后，终端保护壳将通过连接组件将该信息传送至终端中，以令终端与被控对象建立起短距离通信连接。或者，若终端尚未确定被控对象的空间方位，则终端将根据标签标识来获取与被控对象之间的空间方位信息。其中，终端和被控对象之间建立起数据连接。
示意性的，本处介绍一下终端通过终端保护壳中的超宽带天线与通讯标签之间通过UWB技术确认空间方位的方法。请参见图7，图7是本申请实施例提供的一种终端保护壳中超宽带天线的设置示意图。在图7中，本申请提供的终端保护壳中的超宽带天线的数量包括第一天线710、第二天线720和第三天线730。
其中，第一天线710和第二天线720组成第一天线组，第一天线组用于检测终端保护壳在第一方向上与通讯标签之间的角度。第二天线720和第三天线730组成第二天线组，第二天线组用于检测终端保护壳在第二方向上与通讯标签之间的角度。第一天线710、第二天线720和第三天线730不在一条直线上。
其中，在一种定位效果较为理想的方式中，第一方向与第二方向互相垂直。在图7中，第一天线组所在平面和第二天线组所在平面互相垂直。在终端具体测量通讯标签和自身之间的角度的流程中，终端可以通过第一天线组和第二天线组共同参与。终端基于PDoA (Phase Difference of Arrival，到达相位差)测角原理，可以测量通讯标签相对于第一天线组在第一方向上的角度，并可以测量通讯标签相对于第二天线组在第二方向上的角度。
在一种可能的方式中，第一方向是水平方向，第二方向是垂直方向。在另一种可能的方式中，第一方向是垂直方向，第二方向是水平方向。也即，本申请提供的套接有终端保护壳的终端，能够测量贴附有通讯标签的被测对象相对于终端的水平角度以及垂直角度。
步骤640，响应于保护壳处于睡眠状态，终端保护壳控制保护壳中除壳体之外的部件的运行功耗低于第二阈值。
在本例中，终端保护壳能够在睡眠状态中以较低功耗运行。其中，由于壳体是非电子元件，则终端保护壳实际控制保护壳中除壳体之外的部件以低于第二阈值的运行功耗运行。其中，第二阈值可以是200毫瓦、300毫瓦或500毫瓦等数值，本申请实施例对此不作限定。
步骤650，响应于通讯标签处于睡眠状态，通讯标签的功耗低于第一阈值运行。
示意性的，通讯标签在处于睡眠状态时，通讯标签的功耗将低于第一阈值。
在本申请实施例中，可选地，第一阈值小于第二阈值。在该控制条件下，通讯标签能够在不补充电能的情况下保持较长的工作时长。
综上所述，本申请实施例提供的定位系统，能够令终端在套接上终端保护壳之后，具备确定贴附了通讯标签的被控设备的方向的能力。由于原本终端控制被控设备可能需要用户手动打开终端中的应用，通过应用与被控设备建立数据连接，之后才能够通过终端控制被控设备。而基于本申请提供的方案，终端能够在指向被设备时自动于被控设备建立相应的通信连接，在此基础上，终端能够快速的控制被控设备。除此之外，终端和被控设备还无需更改现有的结构，从而大幅降低了使用成本，并使得本申请的容易推广使用，为广大的现有终端提供控制现有的被控对象的能力。
请参考图8，图8是本申请实施例提供的一种控制方法，该控制方法应用在终端保护壳中。终端保护壳包括睡眠状态和唤醒状态，该方法包括：
步骤810，响应于保护壳处于唤醒状态，通过超宽带天线接收超宽带信道中的标签标识。
在本例中，保护壳在唤醒状态时，将通过内置的超宽带天线接收超宽带信道中的标签标识。其中，标签标识可以是通讯标签通过数据帧发送的数据。
步骤820，将标签标识通过连接组件发送至终端中，以令终端与被控对象建立短距离通信连接或获取被控对象的空间方位信息。
在本例中，保护壳中的电子元件能将标签标识通过连接组件发送至终端中。相应的，终端在获取该标签标识后，能够再确定该标签标识绑定的被控对象的标识，从而与该被控对象建立数据连接。或者，终端还能够通过保护壳中的UWB天线接收标签标识时获取的角度信息，确定自身是否正对被控对象，从而在自身正对被控对象时，与被控对象建立数据连接。
可选的，响应于保护壳处于第一唤醒周期，终端保护壳通过处于水平方向上的超宽带天线检测与标签标识之间的第一相对位置参数；响应于保护壳处于第二唤醒周期，通过处于垂直方向上的超宽带天线检测与标签标识之间的第二相对位置参数；通过终端连接组件将第一相对位置参数和第二相对位置参数发送至终端中；其中，第一唤醒周期和第二唤醒周期交替出现在保护壳的工作周期中。
可选的，在一种可能的方式中，保护壳响应于通过超宽带天线接收到标签标识，确定标签标识对应的目标颜色，目标颜色是标签标识对应的通讯标签的外壳颜色；保护壳指示终端保护壳中的指示灯发出目标颜色的光线。
请参考图9，图9是本申请实施例基于图8提供的一种终端控制被控对象的场景示意 图。在图9中，套接有终端保护壳的终端910是用户的手机，通讯标签包括UWB标签921、UWB标签922、UWB标签923和UWB标签924。其中，UWB标签921贴附在冰箱931上。UWB标签922贴附在电视932上。UWB标签923贴附在门锁933上。UWB标签924贴附在蓝牙音箱934上。
需要说明的是，终端910将在上述UWB标签921、UWB标签922、UWB标签923和UWB标签924贴附到相应的设备上后，在终端中输入每一个标签对应的设备ID。示意性的，冰箱931的设备ID是冰箱的WiFi名称。电视932的设备ID是电视的WiFi名称。门锁933的设备ID是门锁的蓝牙标识。蓝牙音箱934的设备ID是音箱的蓝牙标识。其中，由于UWB标签922贴附在电视932的背面，因此，UWB标签922通过虚线示出。
在实际应用中，终端910可以在正对其中一个设备3秒或者摇一摇后，自动处于控制该设备的状态。一种可能的方式中，终端910将在显示屏中显示控制的被控对象的遥控界面。另一种可能的方式中，终端910黑屏并启动麦克风，采集用户的语音指令，直接根据用户的语音指令控制对应的被控对象。在另一种可能的方式中，终端910黑屏并通过触摸屏采集用户在触摸屏上的手势，根据不同的手势控制对应的被控对象。例如，双指相向合拢的手势表示开启指令。双指相离扩张的手势表示关闭指令。双指向屏幕外侧滑动表示增大指令。双指向屏幕内侧滑动表示减小指令。
示意性的，结合本申请中终端保护壳提供的红外线发射装置，在终端确定正对的被控对象之后，终端能够根据被控对象的设备类型，选择不同的控制方式。在一种可能的方式中，当被控对象是传统的家电时，终端通过终端保护壳中的红外线发射装置控制该被控对象。在另一种可能的方式中，当被控对象是智能家电时，终端可以通过WiFi或蓝牙与被控对象建立数据连接，从而控制被控对象。
示意性的，结合本申请提供的新型终端保护壳和通讯标签，用户能够以最智能的方式快速控制对应的设备。请参见图10，图10是基于图9所示实施例提供的一种控制设备的示意图。在图10中，当用户摇一摇终端910时，终端910激活UWB功能。当终端910正对门锁933时，终端910启动语音助手，并播放提示音“请对门锁下达指令”，或者是简单的提示音“嘀”、“嘟”或“咚”等。此时，用户可以下达语音指令“反锁”，此时，门锁将自动反锁，执行该指令，省去了用户起身手动反锁或者在手机中手动寻找到相应的控制应用，启动应用后再行控制门锁的繁琐步骤，提升了用户控制门锁的便捷性。
示意性的，套接有终端保护壳的终端通过UWB天线和贴附在被控对象上的通讯标签形成交互，使得终端具有空间感知能力。当用户将各个通讯标签贴附在被控对象上后，需要初始化该通讯标签，以在终端中记录被控对象与通讯标签相互之间的绑定关系。当终端启动置于终端保护壳中的UWB接收机时，会一次接收到空间中各个通讯标签发来的信号，终端筛选出正前方的通讯标签，追踪到其对应的被控设备，再通过WiFi、蓝牙或红外与其互动。若被控对象是带有显示屏的设备，终端能够在对准该设备经过指定时长后，自动投屏到该显示屏或者显示该设备的遥控器界面。示意性的，指定时长可以是2秒、3秒或者5秒等固定数值的时间长度。
在本申请中，终端可以通过角度标准确定其正对的被控对象。例如角度标准可以是水平角度大于-10°且小于10°，竖直角度大于0°的通讯标签所贴附的被控对象是终端所需控制的被控对象。需要说明的是，上述角度条件仅为示意性说明，不对本申请实施例形成限定。
步骤830，响应于保护壳处于睡眠状态，控制保护壳中除壳体之外的部件的运行功耗低于第二阈值。
示意性的，本申请实施例中，套接了保护壳的终端与通讯标签的交互示意图可以参考图11，图11是本申请实施例提供的一种信息收发情况的示意图。在图11中，通讯标签1101、通讯标签1102、通讯标签1103和通讯标签1104发送各自的标签标识的时段不同，使得同 一时刻，UWB信道中最多存在一个通讯标签发送的标签标识。其中，套有终端保护壳的终端1105能够接收到标签标识。
其中，第一时段t11和第一时段t12是通讯标签1101发送标签标识的时段。第二时段t21和第二时段t22是通讯标签1102发送标签标识的时段。第三时段t31和第一时段t32是通讯标签1103发送标签标识的时段。第四时段t41和第四时段t42是通讯标签1104发送标签标识的时段。
针对接收端，第五时段t51是终端通过水平方向的UWB天线接收信号的时段，也即第一唤醒周期。第五时段t52是终端通过垂直方向的UWB天线接收信号的时段，也即第二唤醒周期。在图11中，已标注出的时段均为唤醒时段，未标注出的时段均为睡眠时段。相应的，唤醒时段是唤醒状态所处于的时段，睡眠时段是睡眠状态所处于的时段。
示意性的，在本申请实施例中，套有手机保护壳的终端用于接收UWB信号，通讯标签用于发送UWB信号。为了避免通讯标签发射信号时冲突，通讯标签端的工作过程符合CCA(Clear Channel Access，信道评估)协议。通讯标签进入唤醒状态后，先侦听UWB信道，当UWB信道空闲时发送标签标识；当UWB信道被占用时进行侦听直到信道空闲。
请参考图12，图12是基于图11所示实施例提供的一种UWB信号发射时序示意图。在图12中，图中的有向线段的起点表示该UWB信号的发射端。由于UWB信号是广播形式发出，因此其余UWB设备是接收端，在图12中，通过有向线段的与横线的交汇处以及终点表示该UWB信号的接收端。例如，以UWB信号12A为例，该信号12A的发射端是通讯标签1102，接收端包括套有终端保护壳的终端1105、通讯标签1101、通讯标签1103和通讯标签1104。
综上所述，本申请实施例提供的方案，套接与终端保护壳的终端与贴附有通讯标签的被控设备之间的UWB通信协议简单，无需其中的主控设备发起控制帧长度和时序的操作，降低了通信难度。
可选地，终端与通讯标签之间的接入方式是异步接入，标签只发送信号而不接收信号，有效降低了贴附在被控设备上的通讯标签的功耗，提高了通讯标签的续航能力。
请参考图13，图13是本申请实施例提供的一种标识的发送方法的流程图，应用在通讯标签中，所述方法包括：
步骤1310，响应于通讯标签处于睡眠状态，在睡眠状态中指定的监听周期监听超宽带信道占用状态，超宽带信道占用状态包括占用状态和空闲状态，占用状态用于指示超宽带信道被占用。
步骤1320，响应于超宽带信道占用状态处于占用状态，在预定睡眠时段后再次监听超宽带信道占用状态。
步骤1330，响应于超宽带信道占用状态处于空闲状态，进入唤醒状态。
步骤1340，响应于通讯标签处于唤醒状态，向外广播通讯标签的标签标识。
综上所述，本申请实施例提供的应用在通讯标签中的标识的发送方法，能够令通讯标签只发送而不接收信号，有效降低了通讯标签的功耗，提高了通讯标签的续航能力。
可选地，各个通讯标签之间可以采用CCA检测冲突，当检测到冲突后采用随机延时，比如采用ALOHA协议，以提高UWB的信道容量。
可选地，各个通讯标签采用动态异步接入的方式，无需感知其它通讯标签的存在情况，拓展了通讯标签的应用场景，提高了终端控制多个被控设备的能力。
