可选的,UWB标签设置有USB接口,通过该USB接口为UWB标签充电,以维持UWB标签的续航能力。
其中,在充电场景下,可以使用USB线连接UWB标签和IoT设备,对应的,UWB标签和IoT设备建立充电连接关系,且IoT设备仅为UWB标签供电,UWB标签和IoT设备无数据通信连接关系。

步骤203,终端设备确定UWB标签所表征IoT设备的设备信息。
基于UWB标签和其表征IoT设备之间的关系,终端设备可以根据UWB标签广播的数据帧,确定该UWB标签所表征IoT设备的设备信息。

针对终端确定UWB标签所表征IoT设备的设备信息的方式,以确定设备标识为例,可以包括以下几种情况:
1、数据帧中添加有UWB标签表征的IoT设备的设备标识。
在一种可能的实施方式中,UWB标签将其表征的IoT设备的设备标识添加至数据帧中,向终端设备发送数据帧。对应的,终端设备接收到UWB标签发送的数据帧,从中提取出该UWB标签所表征的IoT设备的设备标识。
2、数据帧中添加有UWB标签的标签标识,终端设备中存储有UWB标签和IoT设备之间的映射关系。
在另一种可能的实施方式中,UWB标签将自身标签标识添加至数据帧中,向终端设备发送数据帧。对应的,终端设备接收到UWB标签发送的数据帧,从中提取出该UWB标签对应的标签标识,并根据该标签标识从映射关系中获取设备标识,该设备标识就是该UWB标签所表征IoT设备的设备标识。
可选的,对于新增UWB标签与其所表征IoT设备之间的映射关系,用户可以直接在终端中输入UWB标签和IoT设备之间的映射关系;可选的,当UWB标签和IoT设备之间建立绑定关系时,UWB标签可以向终端发送绑定请求,该绑定请求中包含UWB标签的自身标签标识和IoT设备的设备标识,对应终端接收到UWB标签和IoT设备之间的绑定请求,建立UWB标签和IoT设备之间的映射关系。可选的,也可以由IoT设备向终端发送绑定请求。
3、数据帧中添加有UWB标签表征的IoT设备的设备标识和位置信息。

在一个示例性的例子中,若设备信息为设备标识,对应的,终端设备可以根据设备标识确定对应的IoT设备,与IoT设备建立数据通信连接,并对该IoT设备进行控制。
综上所述,本申请实施例中,通过设置可以表征IoT设备的UWB标签,且该UWB标签独立于IoT设备,终端设备可以通过与UWB标签建立UWB通信,实现与该UWB标签所表征的IoT设备建立数据通信连接,并对IoT设备进行控制。由于UWB标签和IoT设备之间的独立性,使得在终端设备与IoT设备建立数据通信连接之前,无需终端设备与IoT设备之间进行任意操作,降低了IoT设备的设备功耗,进而提高了终端设备控制IoT设备的自动化和便捷性。
请参考图3,其示出了本申请另一个示例性实施例提供的IoT设备的控制方法的流程图,本申请实施例以该方法应用于图1所示的终端设备为例进行说明,该方法包括:
步骤301,与UWB标签建立UWB通信,UWB标签用于表征待连接的IoT设备,且UWB标签独立于IoT设备。
本步骤的实施方式可以参考上文实施例,本实施例在此不做赘述。
步骤302,根据至少一个UWB标签发送的数据帧,确定终端设备指向的UWB标签为目标UWB标签。
基于用户需要通过终端设备控制某个IoT设备,一般都会将终端设备指向该IoT设备。因此,基于用户的这一行为习惯,设定终端设备与UWB标签的位置关系为正对关系时,确定终端设备需要与该UWB标签所表征的IoT设备建立数据通信连接,也就是说,当确定终端设备指向某个UWB标签时,将该UWB标签确定为目标UWB标签,后续终端设备可以与目标UWB标签所表征的目标IoT设备建立数据通信连接,并对其进行控制。
为了确定终端设备是否指向某个UWB标签,则终端设备需要具备可以感知UWB标签与其之间的空间位置关系的能力,由于UWB标签可以与终端设备建立UWB通信,而UWB通信可以实现定位功能,因此,在一种可能的实施方式中,在确定终端设备与UWB标签的空间位置关系时,可以采用UWB技术中的定位方式,比如,信号到达角度(Angle of Arrival,AOA)测量:根据数据帧的到达角度确定物体的空间位置;信号到达相位差(Phase Difference of Arrival,PDOA)测量,根据数据帧的到达相位差确定物体的空间位置。本申请实施例对确定空间位置关系所采用的具体定位原理不构成限定。
可选的,针对应用场景中包含终端设备和单个UWB标签,该UWB标签表征单个IoT设备的情况,若用户需要控制该IoT设备,可以直接将终端设备对准该IoT设备对应的UWB标签。对应的,终端设备可以接收到该UWB标签发送的数据帧,并根据该数据帧确定UWB标签表征的IoT设备,从而与该IoT设备建立数据通信连接,继而控制该IoT设备。
可选的,针对应用场景中包含终端设备和多个UWB标签,不同UWB标签表征不同IoT设备。当UWB标签处于工作状态时,终端设备可以接收多个UWB标签发送的数据帧,并根据至少一个UWB标签发送的数据帧,确定出各个UWB标签与终端设备之间的空间位置关系,从中筛选出终端设备指向的目标UWB标签,从而确定用户需要控制的目标IoT设备。
步骤303,根据目标UWB标签发送的数据帧,确定目标UWB标签所表征目标IoT设备的目标设备信息。
在一种可能的实施方式中,当终端设备根据接收到的数据帧,确定出终端设备指向的目标UWB标签,而目标UWB标签唯一表征目标IoT设备;对应终端设备确定出用户想要通过终端设备控制的目标IoT设备。由于数据帧中添加有用于确定IoT设备的设备信息等相关内容,因此,可以根据目标UWB标签发送的数据帧,确定目标UWB标签所表征目标IoT设备的目标设备信息,进而根据该目标设备信息与目标IoT设备建立数据通信连接,并对目标IoT设备进行控制。
其中,UWB标签发送的数据帧中所包含的信息可以为:IoT设备的设备标识和位置信息、IoT设备的设备标识、UWB标签自身的标签标识,对应的,终端基于UWB标签发送的数据帧,与IoT设备建立数据通信连接的方式也可以包括以下三种情况:
1、UWB标签发送的数据帧中包含IoT设备的设备标识以及位置信息,终端设备用于根据设备标识和位置信息与IoT设备建立数据通信连接并进行控制。
其中,设备标识为UWB标签所表征IoT设备的设备标识。设备标识可以是唯一标识该IoT设备的标识。比如,设备标识可以是IoT设备的机器码、设备编号、设备名称等,本申请实施例对此不构成限定。
其中,位置信息可以是UWB标签的位置信息,也可以是IoT设备的位置信息。
针对位置信息是UWB标签的位置信息,在应用场景中,UWB标签与其表征的IoT设备放置在相同位置处,对应的,可以采用UWB标签的位置信息代替IoT设备的位置信息。
针对位置信息是IoT设备的位置信息,在应用场景中,UWB标签可以与其表征的IoT设备放置在相同位置处,UWB标签也可以与IoT设备放置在不同位置。
在一种可能的实施方式中,目标UWB标签在发送数据帧时,可以在数据帧中携带目标IoT设备的目标设备标识和目标位置信息,或在数据帧中携带目标IoT设备的目标设备标识,以及目标UWB标签的目标位置信息,对应的,终端设备接收到目标UWB标签发送的数据帧,可以从数据帧中获取目标IoT设备的目标设备标识和目标位置信息,从而根据该目标设备标识和目标位置信息与目标IoT设备建立数据通信连接,以实现对目标IoT设备进行控制。
2、UWB标签发送的数据帧中包含IoT设备的设备标识,终端设备用于根据设备标识与IoT设备建立数据通信连接并进行控制。
在另一种可能的实施方式中,UWB标签在发送数据帧时,携带UWB标签所表征的IoT设备的设备标识,则对应的,终端设备接收到各个UWB标签发送的数据帧,可以确定出各个UWB标签所表征的IoT设备的设备标识。
对应的,当终端设备确定出其指向的目标UWB标签后,可以从目标UWB标签发送的数据帧中,获取到目标UWB标签所表征目标IoT设备的目标设备标识,进而基于该目标设备标识与IoT设备建立数据通信连接,以实现对目标IoT设备进行控制。
3、UWB标签发送的数据帧中包含标签标识,且终端设备中存储有UWB标签与IoT设备之间的映射关系,终端设备用于根据标签标识从映射关系中获取设备标识,并根据设备标识与IoT设备建立数据通信连接并进行控制。
其中,标签标识可以是唯一标识UWB标签的信息,比如,UWB标签的标签编号、UWB标签的标签名称等。
在一种可能的实施方式中,终端设备中预先存储有各个UWB标签和其表征的IoT设备之间的映射关系,该映射关系可以是标签标识和设备标识的对应关系。
在一个示例性的例子中,UWB标签和IoT设备之间的映射关系可以如表一所示:
表一
标签标识 设备标识
UWB标签1 IoT设备B
UWB标签2 IoT设备A
UWB标签4 IoT设备D
在一种可能的实施方式中,UWB标签在数据帧中携带标签标识。对应的,终端设备接收到UWB标签发送的数据帧后,从数据帧中获取到UWB标签的标签标识,从而根据映射关系,确定出标签标识对应的设备标识,进而根据该设备标识确定出UWB标签所表征的IoT设备。
可选的,当终端设备确定出所指向的目标UWB标签后,即可以从目标UWB标签所发送的数据帧中,获取到目标UWB标签的标签标识,进而基于该标签标识与映射关系中国获取目标UWB标签所表征目标IoT设备的设备标识,并基于该设备标识与IoT设备建立数据通信连接,从而控制该IoT设备执行预设操作。
可选的,针对UWB标签发送的数据帧中仅携带标签标识的场景,终端中需要预先存储有UWB标签和IoT设备之间的映射关系,在一个示例性的例子中,终端中存储该映射关系的过程可以包括以下步骤:
一、响应于绑定操作,获取待绑定UWB标签的标签标识。
为了使得终端可以根据数据帧中包含的标签标识,确定UWB标签表征的IoT设备,在一种可能的实施方式中,通过在终端设备中进行绑定操作,则对应的终端设备接收到绑定操作,获取待绑定的UWB标签的标签标识。
二、响应于对IoT设备的选择操作,建立标签标识与IoT设备对应设备标识之间的映射关系。
在一种可能的实施方式中,终端设备中可以预先注册不同应用场景对应的IoT设备。比如,房间1对应IoT设备A~C,房间2对应IoT设备D~G,对应的,用户可以在终端设备中查看位于不同应用场景中的IoT设备,当用户需要将UWB标签和IoT设备绑定时,可以在终端设备中选择IoT设备,并输入与该IoT设备绑定的UWB标签的标签标识。对应的,终端设备接收到对IoT设备的选择操作,可以将IoT设备的设备标识和标签标识绑定,从而在终端设备中建立UWB标签和其表征的IoT设备的映射关系。
可选的,用户也可以直接将标签标识和设备标识的对应关系输入终端设备中,对应的,终端设备中建立标签标识与IoT设备对应设备标识之间的映射关系。
在另一种可能的应用场景中,UWB标签和IoT设备之间的映射关系并非是永久绑定的,用户可以根据需求,修改或删除UWB标签和IoT设备之间映射关系。比如,修改前,UWB标签1用于表征IoT设备A,修改后,UWB标签1用于表征IoT设备D。对应的,用户需要在终端设备中删除UWB标签1与IoT设备之间的映射关系,并重新进行UWB标签1和IoT设备D之间的绑定操作。
对应的,在一种可能的实施方式中,当终端设备接收到解绑操作,可根据解绑操作指示的UWB标签的标签标识,删除该标签标识与设备标识之间的对应关系,从而删除UWB标签所指示的映射关系。
步骤304,根据目标设备信息与目标IoT设备建立数据通信连接,并对目标IoT设备进行控制。
其中,目标设备信息是唯一标识目标IoT设备的信息,比如,目标设备信息可以是目标设备标识或目标IoT设备的目标位置信息。
在一种可能的实施方式中,当终端设备确定出目标设备信息后,可以与该目标设备信息指示的目标IoT设备建立数据通信连接,进而实现对目标IoT设备的控制。
其中,终端设备与目标IoT设备之间连接方式可以为WiFi连接或蓝牙连接,不同连接方式下,终端设备与目标WiFi连接之间建立数据通信连接的方式并不相同。在一个示例性的例子中,终端设备与目标IoT设备建立数据通信连接的过程可以包括以下步骤:
一、若目标IoT设备与终端设备的连接方式为WiFi连接,根据目标IoT设备的设备标识,通过路由设备与目标IoT设备建立WiFi数据通信连接,其中,目标IoT设备与终端设备均接入路由设备。
在一种可能的应用场景中,目标IoT设备和终端设备连接有相同的WiFi,也就是说,目标IoT设备与终端设备均通过同一路由设备接入网络,对应的,当终端设备需要与目标IoT设备建立数据通信连接时,可以根据目标IoT设备的设备标识,通过该路由设备与目标IoT设备建立WiFi数据通信连接。
针对具体建立数据通信连接的方式,在一个示例性的例子中,终端设备可以向路由设备发送连接建立指令。其中,连接建立指令中包含目标IoT设备对应的设备标识,对应的,路由设备在接收到连接建立指令后,根据连接建立指令中携带的目标IoT设备的设备标识,向目标IoT设备发送连接建立指令,目标IoT设备接收到该连接建立指令,与终端设备建立WiFi数据通信连接。
二、若目标IoT设备与终端设备的连接方式为蓝牙连接,根据目标IoT设备的设备标识,通过蓝牙组件与目标IoT设备建立蓝牙数据通信连接。
在另一种可能的实施方式中,终端设备可以与目标IoT设备建立蓝牙数据通信连接。也就是说,若目标IoT设备与终端设备的连接方式为蓝牙连接,终端设备可以根据目标IoT设备对应的设备标识,通过蓝牙组件与目标IoT设备建立蓝牙数据通信连接。
针对具体建立蓝牙数据通信连接的方式,在一种可能的实施方式中,终端设备和IoT设备均开启蓝牙功能。其中,终端设备可以接收到其他IoT设备广播的蓝牙信号,该蓝牙信号中可以携带有各个IoT设备对应的设备标识,终端设备可以根据目标IoT设备对应的设备标识,从接收到的多个蓝牙信号中确定出目标蓝牙信号。其中,目标蓝牙信号是由目标IoT设备广播的,并与目标IoT设备建立蓝牙数据通信连接。
可选的,终端设备也可以直接广播包含蓝牙连接指令,该蓝牙连接指令中包含目标IoT设备对应的设备标识。当目标IoT设备接收到该蓝牙连接指令后,确定出设备标识与自身设备标识一致,与终端设备建立蓝牙数据通信连接。
在一种可能的实施方式中,当终端设备确定出用户想要控制的目标IoT设备后,可以与目标IoT设备建立蓝牙数据通信连接或WiFi数据通信连接,并基于建立好的数据通信连接控制目标IoT设备。
可选的,终端设备与目标IoT设备之间的连接方式还可以包括红外连接、NFC连接等。
为了避免用户误操作,导致终端设备与目标IoT设备建立无效数据通信连接,占用目标IoT设备的设备资源。在一种可能的实施方式中,设置有连接条件,也就是说,终端设备需要在满足该连接条件的情况下,允许与目标IoT设备建立数据通信连接。
其中,由于不同IoT设备的功能不同,针对不同IoT设备设置有不同的连接条件,使得用户针对不同IoT设备可以采用不同操作,进一步提高建立数据通信连接的准确性。比如,若IoT设备A对应的连接条件为触控条件,IoT设备B对应的连接条件为手势条件,当终端设备确定出目标IoT设备为IoT设备A。但是接收到用户的手势操作,显然,手势操作与IoT设备对应的触控条件不满足,可能是目标IoT设备的确定不准确,与用户期望不对应。此时,可以停止继续与IoT设备A建立数据通信连接,避免建立错误的数据通信连接。
在一种可能的实施方式中,当终端设备确定出目标IoT设备后,继续判断终端设备是否满足该目标IoT设备对应的连接条件,若满足目标IoT设备对应的连接条件,与目标IoT设备建立数据通信连接,并对目标IoT设备进行控制;若不满足目标IoT设备对应的连接条件,则停止与目标IoT设备建立数据通信连接。
其中,连接条件包括指向时长条件、手势条件、触控条件、传感器条件和语音控制条件中的至少一种。
针对将指向时长条件确定为连接条件的场景:终端设备确定指向目标UWB标签的时长超过时长阈值,确定用户想要终端设备与目标UWB标签所表征的目标IoT设备建立数据通信连接。其中,时长阈值可以是5s,该时长阈值由开发人员预先设置,为默认值,或由用户自行设置。当终端设备确定在5s内均指向目标UWB标签(或终端设备确定在5s内,终端设备与该目标UWB标签均处于正向关系),则确定终端设备满足目标IoT设备对应的连接条件,与目标IoT设备建立数据通信连接,并对目标IoT设备进行控制;反之,停止后续与目标IoT设备建立数据通信连接的步骤。
可选的,指向时长条件可以由用户自行设置,可以针对不同IoT设备设置不同的指向时长条件。比如,IoT设备A对应的指向时长条件为3s,IoT设备B对应的指向时长条件为5s,本申请实施例对此不构成限定。
针对将手势条件确定为连接条件的场景:但终端设备检测到用户进行目标IoT设备对应的预设手势,表示用户需要终端设备与目标IoT设备建立数据通信连接,预设手势可以是“比划OK的手势”,或“滑动终端屏幕”等;反之,若终端并未检测到预设手势,或者检测到的手势操作与预设手势不同,则终端设备停止后续与目标IoT设备建立数据通信连接。
可选的,用户可以为不同IoT设备设置不同的预设手势。比如,IoT设备A对应的手势条件为:检测到用户比划“OK”的手势;IoT设备B对应的手势条件为:检测到用户在终端设备屏幕上绘制预设图案等。
针对将触控条件确定为连接条件的场景:当终端设备检测到用户触摸终端预设位置,比如,指纹识别区域,且检测到该指纹为控制终端设备与目标IoT设备建立数据通信连接的指纹;或终端检测到用户轻触终端设备的屏幕时,与目标IoT设备建立数据通信连接;反之,若终端并未检测到预设触控操作,或者检测到的触控操作与预设触控操作不同,则终端设备停止后续与目标IoT设备建立数据通信连接。
可选的,用户也可以为不同IoT设备设置不同的触控条件,以区分终端设备与不同IoT设备之间建立数据通信连接,提高终端设备与IoT设备建立数据通信连接的准确性。
针对将传感器条件作为连接条件的场景:可以是终端设备检测到用户握持终端进行预设操作时,与目标IoT设备建立数据通信连接。比如,终端设备检测到用户手握持终端设备进行“摇一摇”操作,与目标IoT设备建立数据通信连接。
可选的,用户也可以为不同IoT设备设置不同传感器条件。
针对将语音控制条件作为连接条件的场景:终端设备在确定出目标IoT设备时,可以开启语音检测功能,当检测到与目标IoT设备相关的语音指令时,与目标IoT设备建立数据通信连接。比如,智能电视对应的语音控制条件中指示预设语音指令为“投屏”,当终端设备确定出目标IoT设备为智能电视,且接收到投屏指令,终端设备与智能电视预先建立数据通信连接。
可选的,用户可以为不通过IoT设备设置不同语音控制条件。
由于UWB标签仅用于表征IoT设备,UWB标签和IoT设备可能位于不同空间中。比如,UWB标签位于房间A,而UWB标签所表征的IoT设备位于房间B中,用户可以通过将终端设备指向目标UWB标签,预先令终端设备与目标IoT设备建立数据通信连接,以提高后续控制目标IoT设备的效率。在该应用场景下,若终端设备过早与目标IoT设备建立数据通信连接,显然会增加终端设备与目标IoT设备之间的 连接功耗。因此,在一种可能的实施方式中,设置有距离条件,也就是说,终端设备与目标IoT设备之间的距离需要满足距离条件,允许终端设备与目标IoT设备建立数据通信连接。
基于用户想要通过终端设备控制目标IoT设备进行目标操作时,终端设备与目标IoT设备之间的距离一般采取就近原则。在一种可能的实施方式中,当终端设备确定出目标IoT设备后,获取终端设备与目标IoT设备之间的距离,当确定出该距离小于距离阈值时,根据目标设备信息与目标IoT设备建立数据通信连接,并对目标IoT设备进行控制。
其中,确定终端设备与目标IoT设备之间的距离的方式,由于UWB标签发送的数据帧中包含IoT设备对应的位置信息,在一种可能的实施方式中,终端设备确定出目标IoT设备后,可以从目标UWB标签发送的数据帧中获取目标IoT设备对应的位置信息,并根据该位置信息和自身位置信息,确定终端设备与目标IoT设备之间的距离。
可选的,距离阈值可以由用户根据需求自行设置,或采用系统默认值。比如,距离阈值可以是3m。
综上,在一种可能的实施方式中,当终端设备确定出目标IoT设备后,需要判断终端设备与目标IoT设备之间的距离是否小于距离阈值。若小于距离阈值,继续判断终端是否满足目标IoT设备对应的连接条件,并在满足连接条件后,与目标IoT设备建立数据通信连接并进行控制。
其中,距离判断过程和连接条件判断过程可以同时进行,或先进行距离判断过程,后进行连接条件判断过程;或先进行连接条件判断过程,后进行距离判断过程,本申请实施例对此不构成限定。
本实施例中,基于用户想要通过终端设备控制IoT设备,会将终端设备指向IoT设备的行为习惯。根据终端设备接收到的至少一个UWB标签发送的数据帧,确定出终端设备指向的UWB标签为目标UWB标签,并将目标UWB标签所表征的IoT设备确定为目标IoT设备,与目标IoT设备建立数据通信连接,并对目标IoT设备进行控制,实现了通过UWB标签和终端设备之间的通信,控制目标IoT设备的目的;此外,通过设置连接条件,可以避免用户对终端设备误操作,导致终端设备与目标IoT设备建立无效数据通信连接,进而提高终端设备控制目标IoT设备的准确率。
在一种可能的应用场景中,对于不同的IoT设备,终端设备控制IoT设备所执行的目标操作并不相同。
针对目标IoT设备为智能电视的场景,当终端确定出目标IoT设备为智能电视,终端设备可以控制目标IoT设备执行投屏操作,也就是说,可以将终端设备的当前显示画面传输至智能电视。
在一个示例性的例子中,如图4所示,其示出了本申请一个示例性实施例示出的终端设备控制目标IoT设备的过程示意图。其中,目标IoT设备为智能电视,终端设备410中显示有视频播放界面411,当终端设备确定出目标IoT设备为智能电视后,可以将终端设备410的当前显示画面传输至智能电视420,对应的,智能电视420上显示视频播放界面421。
可选的,在终端设备将当前显示画面传输至智能电视之前,可以在终端设备的显示界面中显示操作确认控件,若用户需要进行投屏操作,可以点击该操作确认控件。对应的,终端设备接收到对操作确认控件的点击操作,可以将终端设备的当前显示画面传输至智能电视,以便用户可以通过智能电视继续观看显示内容。
可选的,若目标IoT设备为智能电视,在一种可能的实施方式中,终端设备中还可以显示智能电视对应的控制界面,且控制界面中还包括智能电视对应的功能控件。比如,视频进度调节控件,用户可以点击该视频进度调节控件,终端设备响应于对该视频进度调节控件的触发操作,控制智能电视调节当前视频播放进度。
针对目标IoT设备为智能家居设备的场景,在一种可能的实施方式中,当终端确定出目标IoT设备为智能家居设备,可以在终端设备中显示该智能家居设备对应的控制界面。其中,控制界面中包括智能家居设备对应的功能控件;用户可以根据需求点击控制界面的功能控件,终端设备响应于对控制界面中功能控件的触发操作,控制智能家居设备执行对应的设备功能。
其中,智能家居设备可以包括:智能冰箱、智能音箱、智能门锁、智能窗帘、智能灯具、智能空调等,本申请实施例对智能家居设备的种类不构成限定。
若目标IoT设备为智能音箱,终端设备中显示的控制界面可以包括:音量调节控件、音乐进度调节控件、播放模式调节控件等;若目标IoT设备为智能门锁,终端设备中显示的控制界面可以包括:密码设置控件、开关控件等;若目标IoT设备为智能窗帘,终端设备中显示的控制界面可以包括:窗帘遮光度调节控件、窗帘开关控件等;若目标IoT设备为智能空调,终端设备中显示的控制界面可以包括:温度调节控件、模式调节控件、风速调节控件、开关控件等;若目标IoT设备为智能灯具,终端设备中显示的控制界面可以包括:灯具开关控件、亮度调节控件、色温调节控件等。
在一个示例性的例子中,如图5所示,其示出了本申请一个示例性实施例示出的终端设备中显示控制界面的示意图。以目标IoT设备为智能空调为例,终端设备中显示有控制界面501,该控制界面501中显示有开关控件502、模式调节控件503、风速调节控件504、温度调节控件505、灯光控件506、上下扫风控件507以及左右扫风控件508。当用户点击模式调节控件503时,终端设备响应于对模式调节控件503 的触发操作,控制智能空调进行工作模式调节。比如,由制冷模式调节为制热模式。
在上文实施例中,终端设备对目标IoT设备进行控制的实现过程中,终端设备需要首先确定其所指向的目标UWB标签,进而基于目标UWB标签与目标IoT设备之间的表征关系,与目标IoT设备建立数据通信连接,进行对其进行控制,可见,终端设备确定目标UWB标签所处的空间位置关系,是实现终端设备准确控制目标IoT设备的前提条件,而由于终端设备与UWB标签建立有UWB通信。因此,在一种可能的实施方式中,终端设备通过UWB组件与UWB标签建立UWB通信,并通过与UWB标签之间的UWB交互,实现对UWB标签对应空间位置关系的确定。
请参考图6,其示出了本申请另一个示例性实施例提供的IoT设备的控制方法的流程图,本申请实施例以该方法应用于图1所示的终端设备为例进行说明,该方法包括:
步骤601,通过UWB组件与UWB标签建立UWB通信。
其中,UWB组件与终端设备可分离,或者,UWB组件设置在终端设备内部。
针对UWB组件与终端设备可分离的场景,UWB组件可以封装为终端配件,比如,手机保护套、手机挂饰等,当终端设备佩戴该终端配件时,终端设备可以通过UWB组件与UWB标签建立UWB通信。
可选的,当UWB组件与终端设备可分离时,UWB组件需要预先与终端设备建立数据通信连接,当建立数据通信连接后,终端设备可以通过UWB组件与UWB标签建立UWB通信。示意性的,该数据通信连接可以包括WiFi连接、蓝牙连接、红外线连接、近距离无线通信(Near Field Communication,NFC)连接等。
在一种可能的实施方式中,UWB标签发送数据帧,终端设备可以通过UWB组件接收UWB标签发送的数据帧,对应的,终端设备可以通过UWB组件与UWB标签建立UWB通信。
由于本申请实施例的应用场景中包含多个UWB标签,且不同UWB标签在工作状态下仅发送数据帧,不进行数据帧接收。为了避免不同UWB标签发送的数据帧的冲突问题,在一可能的实施方式中,UWB标签向终端设备发送数据帧时,需要实时侦听目标信道,并在目标信道空闲时,在目标信道上向终端设备发送数据帧。
其中,UWB标签采用空闲信道评估(Clear Channel Assessment,CCA)技术检测目标信道,并在确定目标信道处于空闲状态时,或目标信道的接收信号强度低于门限值时,通过该目标信道发送数据帧,避免数据帧的发送冲突导致后续无法进行空间位置关系测量,进而可以提高目标信道的容量。
可选的,若UWB标签在第一时刻侦听到目标信道处于占用状态,在第一时刻不广播数据帧,并随机延时至第二时刻。在第二时刻广播数据帧,或在侦听到目标信道处于空闲状态时,继续广播数据帧。其中,在检测到数据帧冲突时,UWB标签可以采用随机接入(ALOHA)协议发送数据帧。
步骤602,根据同一UWB标签发送的数据帧,确定终端设备与UWB标签之间的空间位置关系,空间位置关系包括水平方向角度和竖直方向角度。
为了确定终端设备所指向的UWB标签,也即确定终端设备与至少一个UWB标签之间的空间位置关系,而确定空间位置关系无需确定出UWB标签的具体位置,仅需要确定UWB标签相对于终端设置,是否正对于终端设备,因此,在一种可能的应用场景中,基于UWB技术中的空间定位原理,仅需要确定出UWB标签相对于终端设备的方位角,比如,水平方位角度和竖直方位角度,即可通过判断方位角,来确定出终端设备是否指向该UWB标签。
可选的,基于UWB技术中的空间定位原理,比如,PDOA、AOA等可知,若需要通过终端设备与UWB标签之间的UWB交互,测量终端设备与UWB标签之间的水平方向角度和竖直方向角度,UWB组件需要设置两个不同方向的天线组,每个天线组包含两根天线,用于分别测量水平方向角度和竖直方向角度。比如,第一天线组和第二天线组之间具备预设夹角,预设夹角可以是60度。
在一个示例性的例子中,第一天线组可以是水平天线组,第二天线组可以是竖直天线组。其中,水平天线组包括第一天线和第二天线,第一天线和第二天线为水平方向设置的天线;竖直天线组包括第一天线和第三天线,第一天线和第三天线为竖直方向设置的天线。也即UWB组件包括三根天线,其中,第一天线为公用天线,其既可以用于参与测量水平方向度,也可以参与用于测量竖直方向角度。
由于本申请实施例的应用场景中,最终是为了确定终端是否指向目标UWB标签。因此,UWB组件在设置时,为了减少终端设备的计算量,可以与终端的水平方向和竖直方向对应,即UWB组件的水平天线组与终端设备的水平方向一致,且UWB组件的竖直天线组与终端设备的竖直方向一致。
可选的,以水平天线组和竖直天线组为例,UWB组件也可以包括四根天线,即第一天线、第二天线、第三天线和第四天线。其中,第一天线和第二天线为水平天线组,第三天线和第四天线为竖直方向组,本申请实施例对此不构成限定。
在一个示例性的例子中,如图7所示,其示出了本申请一个示例性实施例的UWB组件中天线的结构示意图。其中,第一天线组包括第一天线701和第二天线702,第二天线组包括第一天线701和第三天线 703,且第一天线701和第二天线702的连线与第一天线701和第三天线703的连线存在预设夹角。
由于在确定终端设备与UWB标签的空间位置关系时,需要通过两组天线来实现,因此,在一种可能的实施方式中,终端设备在接收数据帧时,需要第一天线组和第二天线组交替接收至少一个UWB标签广播的数据帧,也就是说,在第一时刻,通过第一天线组接收UWB标签广播的数据帧,在第二时刻,将第一天线组切换为第二天线组,由第二天线组接收该UWB标签广播的数据帧,进而基于两个天线组分别接收到的同一UWB标签广播的数据帧,确定终端设备与该UWB标签的空间位置关系。
在一种可能的实施方式中,若需要确定UWB标签的空间位置,当UWB组件中的第一天线组处于接收状态时,接收UWB标签发送的数据帧,从而计算得到UWB标签与终端设备的水平方向角度;再将UWB组件由第一天线组切换至第二天线组,再次接收UWB标签发送的数据帧,从而计算得到UWB标签与终端设备的竖直方向角度。
本申请实施例的应用场景中可能包括多个UWB标签,且在测量空间位置关系的过程中,需要切换UWB组件中的天线组。为了避免在切换天线组时,终端设备并未全部接收该应用场景中全部UWB标签广播的数据帧,导致无法在一次天线组切换过程中实现对应用场景中所有UWB标签空间位置关系的测量,从而降低后续在比较和判断终端设备指向或正对的目标UWB标签的准确性。在一种可能的实施方式中,通过在UWB标签广播的数据帧中插入UWB标签的标签标识,使得终端可以通过在切换天线前,记录接收到的数据帧中包含的标签标识。由此,可以基于该标签标识来判断是否接收到该应用场景中可能包括的各个UWB标签广播的数据帧,提高天线组切换时机的准确性。
在一个示例性的例子中,确定同一UWB标签发送的数据帧可以包括以下步骤:
一、通过第一天线组接收至少一个UWB标签广播的数据帧,并根据数据帧中包含的标签标识构建标签集合。
其中,数据帧中包含UWB标签对应的标签标识。标签标识可以是该应用场景中不同UWB标签的编号,比如,UWB标签的编号为3,则该UWB标签广播的数据帧中即包含标签标识“3”,也可以采用不同UWB标签的机器码作为标签标识,本申请实施例对标签标识的类型不构成限定。
为了提高天线组切换时机的准确性,在一种可能的实施方式中,当终端设备通过第一天线组开始接收各个UWB标签广播的数据帧后,从该数据帧中获取到标签标识,并创建标签集合,将该标签标识添加至标签集合中。终端可以通过标签集合中标签标识的变化情况,来预判是否在UWB组件中的第一天线组处于接收状态时,已接收到当前应用场景中包含的各个UWB标签广播的数据帧。
在一个示例性的例子中,若标签标识为UWB标签的编号,则对应的标签集合可以为A={2,3,5},表示当UWB组件中的第一天线组处于接收状态时,已接收到UWB标签2、UWB标签3和UWB标签5广播的数据帧。
二、响应于标签集合停止变化,切换第二天线组接收至少一个UWB标签广播的数据帧。
基于UWB标签实时广播数据帧的特点,终端设备实时将接收到的数据帧中包含的标签标识添加至标签集合中,若标签集合中包含该标签标识,则不重复添加。若标签集合中不存在该标签标识,则继续在标签集合中添加标签标识,直至标签集合停止变化。即一段时间内标签集合中均未添加新的标签标识,表明该应用场景中可能不存在除标签集合中已有标签标识对应的UWB标签之外的UWB标签。则对应的,终端设备可以控制UWB组件切换接收数据帧的天线组,比如由第一天线组切换至第二天线组,以便在第二天线组处于工作状态时,继续接收UWB标签广播的数据帧。
可选的,当终端设备由第二天线组重新切换为第一天线组时,也可以根据上次切换过程中第一天线组处于接收状态时得到的标签集合,来确定由第二天线组件重新切换为第一天线组的时机。由此,可以避免遗漏接收某个UWB标签广播的数据帧,从而导致无法在一次天线组切换过程中对全部UWB标签的空间位置进行测量。
在一个示例性的例子中,若标签集合B={1,2,3,4},表示在UWB组件中的第一天线组处于工作状态时,接收到UWB标签1至4广播的数据帧。那么,为了实现对这四个UWB标签空间位置的测量,当UWB组件中的第二天线组处于工作状态时,需要保证接收到UWB标签1至4广播的数据帧,才可以重新切换至第一天线组。
如图8所示,其示出了本申请一个示例性实施例示出的UWB组件和多个UWB标签的工作时序图。其中,UWB标签包括UWB标签1~UWB标签4。当各个UWB标签处于工作状态时,通过侦听目标信道的信道状态广播数据帧。比如,UWB标签1在T1处侦听到目标信道空闲,在T1时刻广播数据帧后,继续监听目标信道,当目标信道被占用时,继续监听目标信道直至目标信道处于空闲状态,即在T2时刻广播数据帧。对应的,当UWB组件处于工作状态时,首先由水平天线组在第一时间段内接收各个UWB标签广播的数据帧。当确定接收到各个标签广播的数据帧后,由水平天线组切换至竖直天线组,并在第二时间段内通过竖直天线组接收各个UWB标签广播的数据帧。
在一种可能的实施方式中,终端通过UWB组件接收至少一个UWB标签广播的数据帧,并通过数据 帧中包含的标签标识,将接收到的数据帧按照标签标识划分为不同的数据帧组。同一数据帧组中包含的数据帧均由同一UWB标签广播,则对应的,终端设备可以根据同一数据帧组来确定该终端设备与UWB标签之间的空间位置关系。
由于本申请实施例中,UWB组件包括第一天线组和第二天线组,对应的,根据同一UWB标签广播的数据帧中,存在由第一天线组接收到的数据帧和由第二天线组接收到的数据帧。因此,可以根据第一天线组接收到的数据帧确定终端设备和UWB标签之间的水平方向角度,并根据第二天线组接收到的数据帧确定终端设备和UWB标签之间的竖直方向角度。综合得到的水平方向角度和竖直方向角度,确定终端设备与UWB标签之间的空间位置关系。
其中,确定空间位置关系的方法可以包括以下步骤:
一、根据第一天线组接收到的数据帧,确定终端设备与UWB标签之间的水平方向角度。
基于UWB技术中测量角度的原理,可以通过第一天线组接收到的数据帧,来确定终端设备与UWB标签之间的水平方向角度。
可选的,第一天线组可以是水平天线组。
其中,以PDOA为例描述测量水平方向角度的原理为:由于水平天线组包括第一天线和第二天线,当水平天线组处于工作状态时,由于两根天线之间存在一定的距离,可以根据同一数据帧到达两根天线之间的到达相位差,从而计算UWB组件与UWB标签之间在水平方向上的水平方向角度。
在一个示例性的例子中,如图9所述,其示出了本申请一个示例性实施例示出的水平天线组测量水平方向角度的过程示意图。UWB标签901相对于水平天线组的水平方向角度为α,根据几何关系可以得知该水平方向角度与角度θ相等。水平天线组902包括第一天线和第二天天线,第一天线和第二天线之间相距d,UWB标签901广播的数据帧,该数据帧到达水平天线组902中第一天线和第二天线时存在到达相位差,可以根据该到达相位差计算水平方向角度θ。
以图9所示,基于PDOA原理测量角度公式可以表示为:
Figure PCTCN2021121747-appb-000001
其中,θ表示角度(本实施例里可以表示终端设备与UWB标签的水平方位角度),λ表示波长,Δφ表示到达相位差,d表示第一天线和第二天线之间的水平距离。
二、根据第二天线组接收到的数据帧,确定终端设备与UWB标签之间的竖直方向角度。
与上文测量水平方向角度类似,基于UWB技术中测量角度的原理和UWB组件中天线的位置分布情况,可以通过第二天线组接收到的数据帧,来确定UWB组件与UWB标签之间的竖直方向角度。
可选的,第二天线组可以是竖直天线组。
其中,以PDOA为例描述测量竖直方向角度的原理为:竖直天线组包括第一天线和第三天线。当竖直天线组处于工作状态(信号接收状态)时,由于两根天线之间存在预设距离,则可以根据同一数据帧到达第一天线和第三天线的到达相位差,来计算终端设备与UWB标签在竖直方向上的竖直方向角度。其根据到达相位差测量竖直方向角度的原理与测量水平方向角度的原理相同。
在一个示例性的例子中,如图10所示,其示出了本申请一个示例性实施例示出的确定终端设备和UWB标签空间位置关系的过程示意图。其中,该应用场景中包含终端设备1001和UWB标签1002,终端设备1001中设置有UWB组件。UWB标签1002通过目标信道广播数据帧,终端设备1001通过UWB组件接收UWB标签1002广播的数据帧。终端设备1001根据该数据帧,确定终端设备1001与UWB标签1002之间的水平方向角度θ,以及竖直方向角度φ。则对应的UWB标签1002位于终端设备1001水平方向角度+θ,竖直方向角度+φ的位置。
步骤603,根据终端设备与各个UWB标签之间的空间位置关系,确定终端设备指向的UWB标签为目标UWB标签。
在本申请实施例的应用场景中包含多个UWB标签。终端根据不同UWB标签广播的数据帧,分别计算出不同UWB标签与UWB组件之间的空间位置关系,根据该空间位置关系,进而可以确定出终端设备正对着(指向)的目标UWB标签。
其中,确定终端设备是否指向UWB标签,可以通过判断终端设备与UWB标签之间的空间位置关系是否偏离来确定,即确定终端设备与UWB标签之间的水平方向角度是否偏离预设水平角度范围,且终端设备与UWB标签之间的竖直方向角度是否偏离预设竖直角度范围来确定。
在一种可能的实施方式中,预设有终端设备正对(指向)UWB标签时,终端设备与UWB标签之间空间位置关系需要满足的角度范围。由于空间位置关系包含水平和竖直两个方向角度,则对应的终端设备与UWB标签之间的水平方向角度需要满足水平角度范围,且竖直方向角度需要满足竖直角度范围。
其中,当终端设备指向或正对着UWB标签时,终端设备与UWB标签应该位于同一水平平面,在允 许存在误差的情况下,水平角度范围可以是-10度~10度,竖直角度范围可以是0度~90度,本申请实施例在此不做限制。
在一个示例性的例子中,当终端确定出终端设备与各个UWB标签之间的空间位置关系后,各个空间位置关系可以在终端后台显示。举例而言:UWB标签A:水平方向角度-30度、竖直方向角度10度;UWB标签B:水平方向角度-2度、竖直方向角度10度;UWB标签C:水平方向角度35度、竖直方向角度5度;UWB标签D:水平方向角度60度、竖直方向角度20度。基于上文中终端确定指向的筛选条件:水平角度范围可以是-10度~10度,竖直角度范围可以是0度~90度,由于UWB标签B与终端设备的空间位置关系位于该角度范围内,则对应的确定出终端设备指向UWB标签B,即UWB标签B为目标UWB标签。
步骤604,根据目标UWB标签发送的数据帧,确定目标UWB标签所表征目标IoT设备的目标设备信息。
步骤605,根据目标设备信息与目标IoT设备建立数据通信连接,并对目标IoT设备进行控制。
步骤604和步骤605的实施方式可以参考上文实施例,本实施例在此不做赘述。
本实施例中,终端设备通过在UWB组件接收数据帧,实现对终端设备与UWB标签之间空间位置关系(水平方向角度和竖直方向角度)的测量。此外,通过在UWB标签广播的数据帧中携带标签标识,使得在具备多个UWB标签的应用场景中,可以实现对不同UWB标签广播的数据帧的区分。在实现同时对多个UWB标签空间位置关系测量的基础上,避免不同UWB标签广播的数据帧的混淆,有利于提高测量UWB标签空间位置关系的准确性。另外,通过预设水平角度范围和竖直角度范围,基于确定出的多个UWB标签的空间位置关系,从中筛选出终端设备正对(指向)的目标UWB标签,从而使得终端设备可以准确与该目标UWB标签表征的目标IoT设备建立数据通信连接。
由上文实施例可知,在终端设备与目标IoT设备建立数据通信连接的过程中,UWB组件在工作状态下仅接收数据帧,且不进行数据帧广播,即UWB组件仅接收UWB标签广播的数据帧。对应的,UWB标签在工作状态下广播数据帧,且不进行数据帧接收。也就是说,UWB标签在工作状态时,仅广播数据帧,并不会进行数据帧的接收,可以降低UWB标签的功耗;同时在UWB标签广播数据帧时,可以基于CCA和ALOHA协议广播数据帧,可以避免数据帧冲突,从而提高目标信道的容量。
