无线充电技术不需要电缆即可完成功率的传输，因此，无线充电技术越来越受到人们的青睐。
传统的无线充电技术一般将适配器与无线充电装置(如无线充电底座)相连，并通过该无线充电装置将适配器的输出功率以无线的方式(如电磁波)传输至待充电设备，对待充电设备进行无线充电。
按照无线充电原理不同，无线充电方式主要分为磁耦合(或电磁感应)、磁共振以及无线电波三种方式。
目前，主流的无线充电标准包括QI标准、电源实物联盟(power matters alliance，PMA)标准、无线电源联盟(alliance for wireless power，A4WP)。QI标准和PMA标准均采用磁耦合方式进行无线充电。A4WP标准采用磁共振方式进行无线充电。
本发明实施例对无线充电装置的功能进行扩展，使得该无线充电装置不但能够进行无线充电，而且能够在无线充电过程中进行无线数据传输。无线数据传输方式无需准备各种类型的数据线，从而可以简化用户的操作。且可以解决相关技术中，采用有线数据传输、WIFI、移动通信网络、蓝牙等数据传输方式时，传输数度慢、受网络限制等问题。
下面结合附图，详细描述本发明实施例提供的无线充电***和无线充电装置。
图1是本发明实施例提供的无线充电***的示意性结构图。图1中的无线充电***包括无线充电装置10、具有数据处理和传输功能的电子设备20以及待充电设备30。
无线充电装置10包括外部接口11，无线充电控制单元12以及无线数据传输单元13。无线充电控制单元12可用于在外部接口11与电子设备20连接的过程中，根据电子设备20的输出功率对待充电设备30进行无线充电。无线数据传输单元13可用于在无线充电控制单元12根据电子设备20的输出功率对待充电设备30进行无线充电的过程中或待充电设备放置在无线充电装置10上时，通过无线链路将电子设备20中存储的数据(例如可以是数据内容，或数据文件)传输至待充电设备30，或者通过无线链路将待充电设备30中存储的数据(例如可以是数据内容，或数据文件)传输至电子设备20。
本发明实施例提供的无线充电装置10不但能够基于电子设备提供的输出功率对待充电设备进行无线充电，而且能够在无线充电过程中实现电子设备与待充电设备之间的无线数据传输，从而无需准备额外的数据线，简化了用户的操作。另一方面，还可实现快速传输，传输时不受网络限制。
本发明实施例中所使用到的待充电设备可以是指终端，该“终端”可包括，但不限于被设置成经由有线线路连接(如经由公共交换电话网络(public switched telephone network，PSTN)、数字用户线路(digital subscriber line，DSL)、数字电缆、直接电缆连接，以及/或另一数据连接/网络)和/或经由(例如，针对蜂窝网络、无线局域网(wireless local area network，WLAN)、诸如手持数字视频广播(digital video broadcasting handheld，DVB-H)网络的数字电视网络、卫星网络、调幅-调频(amplitude modulation-frequency modulation，AM-FM)广播发送器，以及/或另一通信终端的)无线接口接收/发送通信信号的装置。被设置成通过无线接口通信的终端可以被称为“无线通信终端”、“无线终端”以及/或“移动终端”。移动终端的示例包括，但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信***(personal communication system，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位***(global positioning system,GPS)接收器的个人数字助理(personal digital assistant，PDA)；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。另外，本发明实施例中所使用到的待充电设备或终端还可包括移动电源(power bank)，该移动电源能够接受适配器的充电，从而将能量存储起来，以为其他电子装置提供能量。
本发明实施例对电子设备20的类型不做具体限定。在一些实施例中，电子设备20可为主机设备。在另一些实施例中，电子设备20可以是电脑或智能电视。
本发明实施例对无线充电装置10的具体类型不做限定，例如，可以是无线充电底座，也可以是其他类型的能够将电信号转换成电磁波，从而实现无线充电的装置。
本发明实施例对无线充电装置10的外部接口11的个数和类型不做具体限定。在一些实施例中，无线充电装置10可以包括一个外部接口11，该外部接口11既可以用于接收外部设备提供的充电功率，又可以用于传输外部设备提供的数据。在另一些实施例中，无线充电装置10可以包括多个外部接口11，例如，无线充电装置包括两个外部接口11，其中一个外部接口用于与电子设备相连，另一个外部接口用于与适配器相连。无线充电装置10的外部接口11例如可以包括串口、通用串行总线(universal serial bus，USB)等接口中的至少一个。该USB接口例如可以是USB 2.0接口、USB 3.0接口或TYPE-C接口。
本发明实施例对无线充电控制单元12的无线充电方式不做具体限定。例如，无线充电控制单元12可以基于磁耦合、磁共振和无线电波中的至少一种进行无线充电。
在一些实施中，无线充电控制单元12可以基于传统的无线充电标准进行无线充电。例如，无线充电控制单元12可以基于以下标准中的一种进行无线充电：QI标准、A4WP标准以及PMA标准。
本发明实施例对无线数据传输单元13上传输的数据类型不做具体限定。例如，无线数据传输单元13可以传输以下数据中的至少一种：USB协议格式的数据、DP协议格式的数据、MHL协议格式的数据。进一步地，在一些实施例中，无线数据传输单元13可用于传输多种协议格式的数据。例如，无线数据传输单元13可以同时支持USB协议格式和MHL协议格式的数据的传输。
本发明实施例对无线充电装置10的具体结构不做限定，能够实现无线充电装置10的功能的任意电路结构均可用于本发明实施例。以图2为例，无线充电装置10可以包括：控制单元121(例如可以是MCU)、无线充电单元122和无线数据传输单元13，其中控制单元121和无线充电单元122可共同实现无线充电控制单元12对应的功能。此外，无线数据传输单元13的无线数据传输功能也可以在控制单元121的控制下实现。进一步地，控制单元121还可以通过外部接口11与外接设备进行通信和/或控制信息的交互。换句话说，无线充电装置10内部的控制相关的功能均可集成在控制单元121中，由控制单元121进行统一控制，但本发明实施例不限于此，也可以在无线充电装置10中布置多个控制单元，分别用于实现不同的控制功能。
具体地，控制单元121可以与待充电设备30进行通信，以识别待充电设备30的类型，并确定与待充电设备30匹配的功率等级。以外部接口11的输入功率是直流电功率为例，无线充电单元122可以包括转换电路和线圈等器件，转换电路可用于将外部接口11输入的直流电转换成交流电，线圈可用于将交流电转换成电磁波发射至接收端。
以电子设备20是主机设备，控制单元121是MCU，无线充电装置10是无线充电底座为例，当主机设备通过无线充电底座的外部接口与无线充电底座相连时，MCU识别主机设备能够提供的功率以及主机设备支持的数据交互的类型(如USB 2.0格式的数据、USB3.0格式的数据、图像数据、音视频数据等)。接着，无线充电装置10可以根据主机设备能够提供的功率，按照传统的无线充电标准(如QI或A4WP等)定义的规则，为待充电设备提供多个功率等级，如低功率等级(如5W)和中功率等级(如10W和/或15W)。当然，如果主机设备能够提供更大的功率，本发明实施例还可以对传统的无线充电标准(如QI或A4WP等)进行扩展，从而向待充电设备提供更高的功率等级。
需要说明的是，上文是以无线充电装置10基于传统无线充电标准进行无线充电为例进行举例说明的，但本发明实施例不限于此，无线充电装置10还可以基于自定义的私有标准或协议进行无线充电，如根据自定义的私有标准或协议识别待充电设备的类型，匹配待充电设备的功率等级等。
在一些实现方式中，无线充电装置10可以通过外部接口11与适配器相连，并根据适配器的输出功率对待充电设备30进行无线充电。在另一些实现方式中，无线充电装置10可以用来充当适配器，即将适配器的功能集成在无线充电装置10内部。上述适配器可以是相关技术中的普通的适配器，也可以是本发明实施例提供的输出功率的可控的适配器。
在无线充电时，第一种可能的实现方式是将适配器与无线充电装置相连，从而基于适配器的输出功率对待充电设备进行无线充电。在这种实现方式中，无线充电装置主要的功能是将适配器的输出功率转换成无线功率信号，然后将该无线功率信号传输至待充电设备。
第二种可能的实现方式是直接将无线充电装置作为适配器(即将适配器的功能集成在无线充电装置内部)，利用无线充电装置的输出功率对待充电设备进行充电。在这种实现方式中，无线充电装置不但需要负责通过变压、整流等操作对交流电进行转换，还要负责将转换后的电压和电流以无线的方式发射至待充电设备，从而对待充电设备进行无线充电。下面结合具体的实施例，对以上两种实现方式分别进行详细介绍。
以第一种实现方式为例，如图3所示，外部接口11可以与适配器40相连。当外部接口11与适配器40连接时，无线充电装置10可主要用于无线充电，无线数据传输单元13可以处于空闲状态，或者传输无线充电相关的一些参数信息。
本发明实施例对适配器40的类型不做具体限定。例如，适配器40可以是相关现有技术提供 的普通的适配器。又如，适配器40可以是本发明实施例提供的能够对自身的输出功率进行控制的适配器，这类适配器通常需要与外界进行双向通信，以协商或控制该适配器的输出功率。
以适配器40为普通适配器为例，当无线充电装置10识别到外部接口11连接到该普通的适配器时，无线充电控制单元12可以基于无线充电标准(如QI，A4WP等)定义的规则，为待充电设备提供一个或多个功率等级，如低功率等级(如5W)和中功率等级(如10W和/或15W)。当无线充电装置10检测到待充电设备时，可以基于无线充电标准提供的无线充电协议进行通信，以识别待充电设备的类型，并匹配待充电设备的功率等级。然后，无线充电底座可以基于匹配出的功率等级对待充电设备进行无线充电。
以适配器40为本发明实施例提供的输出功率可调的适配器为例，无线充电装置10中的无线充电控制单元12可以与适配器进行双向通信，以控制(或协商)该适配器的输出功率，并根据该适配器的输出功率对待充电设备30进行无线充电。由上文可知，与相关技术提供的普通的适配器相比，本发明实施例提供的输出功率可控的适配器能够提供更大的输出功率，从而为无线充电领域的快速充电提供了基础。
当无线充电装置10检测到外部接口11与适配器相连时，无线充电装置10可以与适配器进行双向通信。如果该适配器能够支持双向通信，表明该适配器为上文描述的输出功率可控的适配器。此时，无线充电装置10中的无线充电控制单元12可以基于无线充电标准(如QI，A4WP等)定义的规则，为待充电设备提供一个或多个标准的功率等级，如低功率等级(如5W)和中功率等级(如10W和/或15W)。或者，无线充电控制单元12可以扩展传统的无线充电标准(如QI，A4WP等)，使其能够支持更高的功率等级。这样一来，当无线充电装置10检测到外部接口11与输出功率可控的适配器相连时，可以为待充电设备提供更高的功率等级。
可选地，在一些实施例中，无线充电装置10可以按照本发明实施例提供的双向通信协议(详见上文描述的适配器与待充电设备之间的双向通信过程和指令集合)与待充电设备进行双向通信，以提供中功率等级，甚至提供更高的功率等级。
以无线充电装置10为无线充电底座为例，当待充电设备与无线充电底座相连时，无线充电底座可以按照本发明实施例提供的双向通信协议与待充电设备进行双向通信，以识别待充电设备的类型，并对待充电设备进行功率匹配。然后，无线充电底座可以基于匹配出的功率对待充电设备进行无线充电。需要说明的是，功率的匹配过程可以包括电流大小的匹配和电压大小的匹配，以匹配功率等于10W为例，电压和电流可以分别为5V和2A，或者电压和电流可以分别为10V和1A。
需要说明的是，本发明实施例对是无线充电控制单元12与适配器之间的通信内容不做具体限定，只要能够实现控制或协商适配器的输出功率的目的即可。下面结合具体的实施例，对适配器与无线充电控制单元12之间的通信内容进行举例说明。
可选地，在一些实施例中，适配器40是支持第一充电模式和第二充电模式的适配器，且适配器40在第二充电模式下对待充电设备30的充电速度快于适配器40在第一充电模式下对待充电设备30的充电速度，上述与适配器40进行双向通信，以控制适配器40的输出功率可包括：与适配器40进行双向通信，以控制在第二充电模式下的适配器40的输出功率。
需要说明的是，第二充电模式下的适配器40的输出功率可以由无线充电装置10主动确定；或者，可以由无线充电装置10在参考待充电终端的状态或能力的情况下确定；或者，可以由待充电设备30确定，在这种情况下，无线充电装置10主要负责适配器40和待充电设备30之间的信息或指令的传递。
可选地，在一些实施例中，无线充电控制单元12可以直接与适配器40进行双向通信，以协商或控制第二充电模式下的适配器的输出功率。例如，无线充电控制单元12可以本发明实施例提供的双向通信协议(参见上文描述的适配器与待充电设备之间的双向通信过程和指令集合)与适配器40进行双向通信。
可选地，在一些实施例中，上述与适配器40进行双向通信，以控制在第二充电模式下的适配器40的输出功率可包括：与适配器40进行双向通信，以协商适配器40的充电模式。
例如，适配器40可以向无线充电控制单元12发送第一指令，询问无线充电控制单元12是否开启第二充电模式；无线充电控制单元12向适配器发送第一指令的回复指令，第一指令的回复指令用于指示无线充电控制单元12是否同意开启第二充电模式。在第一指令的回复指令指示无线充电控制单元12同意开启第二充电模式的情况下，适配器开启第二充电模式。
本发明实施例对无线充电控制单元12确定是否开启第二充电模式的方式不做具体限定。例如，无线充电控制单元12可以直接同意开启第二充电模式；又如，无线充电控制单元12可以将第一指令发送至待充电设备30，由待充电设备30决定是否开启第二充电模式；又如，无线充电控制单元12可以根据待充电设备30的状态(如待充电设备是否支持第二充电模式，和/或待充电设备的当前电量等)确定是否开启第二充电模式。
可选地，在一些实施例中，上述与适配器40进行双向通信，以控制在第二充电模式下的适配器40的输出功率可包括：与适配器40进行双向通信，以控制在第二充电模式下的适配器的输出电压。
例如，适配器40可以向无线充电控制单元12发送第二指令，询问无线充电控制单元12当前的输出电压是否合适；无线充电控制单元12可以向适配器40发送第二指令的回复指令，第二指令的回复指令用于适配器40当前的输出电压合适、偏高或偏低，以便适配器40根据第二指令的回复指令调整自身的输出电压。
本发明实施例对无线充电控制单元12确定在第二充电模式下的适配器的输出电压的方式不做具体限定。可选地，在一些实施例中，无线充电控制单元12可以主动确定在第二充电模式下的适配器的输出电压。例如，无线充电控制单元12识别出该适配器为输出功率可控的适配器之后，直接将该适配器40的输出电压调整到预设的较高档位。可选地，在另一些实施例中，无线充电控制单元12可以与待充电设备30进行通信，并基于待充电设备30的反馈信息控制在第二充电模式下的适配器的输出电压。
可选地，在一些实施例中，上述与适配器进行双向通信，以控制在第二充电模式下的适配器的输出功率可包括：与适配器进行双向通信，以控制在第二充电模式下的适配器的输出电流。
例如，适配器40可以向无线充电控制单元12发送第三指令，询问无线充电控制单元12适配器的输出电流的电流值，或无线充电装置支持的最大充电电流；无线充电控制单元12可以向适配器40发送第三指令的回复指令，第三指令的回复指令用于指示适配器的输出电流的电流值，或者无线充电装置支持的最大充电电流，以便适配器40根据第三指令的回复指令调整自身的输出电流。
本发明实施例对无线充电控制单元12确定在第二充电模式下的适配器的输出电流的方式不做具体限定。可选地，在一些实施例中，无线充电控制单元12可以主动控制在第二充电模式下的适配器的输出电流。例如，无线充电控制单元12识别出该适配器为输出功率可控的适配器之后，直接将该适配器的输出电流调整到预设的较高档位。可选地，在另一些实施例中，无线充电控制单元12可以与待充电设备30进行通信，并基于待充电设备30的反馈信息控制在第二充电模式下的适配器的输出电流。
需要说明的是，本发明实施例对无线充电控制单元12根据适配器40的输出功率对待充电设备30进行无线充电的过程不做具体限定。在一些实施例中，可以沿用传统的无线充电标准(如QI或A4WP)所提供的无线充电协议对待充电设备30进行无线充电。在另一些实施中，可以采用本发明实施例提供的双向通信协议(参见上文描述的适配器与待充电设备之间的双向通信过程和指令集合)对待充电设备30进行无线充电。

传统的无线充电过程的通信过程仅包括待充电设备的识别和功率等级确认过程，本发明实施例基于自定义的双向通信协议，首先识别待充电设备的类型(即待充电设备是否为支持第二充电模式的适配器)，从而将本发明实施例提供的双向通信协议应用到无线充电领域，为无线充电领域的快速充电提供了基础。
可选地，在一些实施例中，无线充电控制单元12还可用于在无线充电控制单元12根据适配器40的输出功率对待充电设备30进行无线充电的过程中，与待充电设备30进行双向通信，以调整无线充电控制单元12的输出功率。
传统的无线充电过程在完成待充电设备的功率匹配之后，则无法调整无线充电控制的输出功率，本发明实施例修改无线充电控制单元12与待充电设备30之间的通信协议，在无线充电控制中，保持无线充电控制单元12与待充电设备30之间的双向通信，从而可以根据实际需要实时调整无线充电控制单元12的输出功率，提高了无线充电过程的灵活性。
以第二种实现方式(即无线充电装置10直接作为适配器的实现方式)为例，无线充电控制单元12还可用于接收交流电；将交流电的输入功率转换成无线充电装置10的输出功率；根据无线充电装置10的输出功率对待充电设备30进行无线充电。
将适配器的功能集成在无线充电装置中，可以减少无线充电过程中需要连接的设备或装置的数量，简化实现。
应理解，可以在无线充电装置10中集成普通适配器的功能，也可以在无线充电装置10中集成本发明实施例提供的输出功率可调的适配器的功能。以在无线充电装置10中集成本发明实施例提供的输出功率可调的适配器的功能为例，无线充电装置10可与待充电设备进行双向通信，从而控制无线充电装置10的输出功率。无线充电装置10与待充电设备之间的双向通信机制可以采用与有线充电过程中的输出功率可调的适配器与待充电设备之间的双向通信机制(具体参见上文)类似的通信机制，不同之处在于无线充电装置10与待充电设备之间的充电功率是以无线方式传输的。下面结合具体的实施例对无线充电装置10与待充电设备之间的通信机制和充电控制方式进行详细描述。
可选地，在一些实施例中，无线充电装置10可支持第一充电模式和第二充电模式，且无线充电装置10在第二充电模式下对待充电设备30的充电速度快于无线充电装置10在第一充电模式下对待充电设备30的充电速度，与待充电设备30进行双向通信，以控制无线充电装置10的输出功率可包括：与待充电设备30进行双向通信，以控制在第二充电模式下的无线充电装置10的输出功率。

上文结合不同实施例对无线充电装置10的功能进行了详细描述，但本发明各个实施例之间相互独立，例如，无线充电装置10可以仅实现图1实施例描述的功能，或者，无线充电装置10可以仅实现图3实施例描述的功能，或者，无线充电装置10可以同时实现图1实施例和图3实施例描述的功 能。
下面结合图4，对本申请实施例的近距离无线通信***进行介绍。
如图4所示，近距离无线通信***100包括发送端设备110和接收端设备120。发送端设备110与接收端设备120可以现实非接触式的高速数据传输，可选地，在发送端设备110的集成电路(Integrated Circuit，IC)芯片内封装极高频(Extremely high frequency，EHF)天线，从而，发送端设备110可以基于高载波频率(例如，60GHz)实现高速的数据无线传输(例如，最高可达6GB/s的传输速度)。可选地，接收端设备120的IC芯片内也可以封装EHF天线，从而，可以实现发送端设备110与接收端设备120之间的双向通信。可选地，发送端设备110与接收端设备120之间通过电磁信号实现数据的无线传输。
应理解，基于高载波频率的近距离无线通信具有低功耗、体积小、传输速率快、非接触传输等优点，还可以实现即插即用模块的功能，可以大幅提高的信号完整性，支持更灵活的***实现，降低待机功耗，增加带宽幅度与数据传输的安全性，兼容对高速视频信号的支持等特点。

比如，在配备无线充电装置的高铁途中，用户想要下载某部电影A，但是由于该电影A的数据量较大(如5GB或8GB)，并且目标终端的移动通信网络的数据流量有限，若使用目标终端的移动通信网络的数据流量来下载该电影A，那么会导致目标终端的数据流量消耗过多，甚至需要额外付费购买移动通信套餐外的流量。在这种情况下，用户可以使用目标终端将需要下载的数据以下载请求的形式发送至无线充电装置。其中，上述数据可以包括视频、音频、图片、以及文档等多媒体数据，数据标识则可以为多媒体数据的名称，比如电影“XX历险记”。需要说明的是，该数据标识用于唯一标识该多媒体数据，在其他实施例当中，该数据标识还可以为多媒体数据的编号等。
步骤S102，根据数据标识在存储器中确定对应的目标数据。
比如，在从目标终端处接收到关于该电影“XX历险记”的数据下载请求后，无线充电装置可以根据该数据下载请求，从存储器中查找关于该电影的目标数据。可以理解的是，上述电影的目标数据即指电影的可播放多媒体文件。
步骤S103，当检测到无线充电装置与目标终端建立无线数据传输连接时，通过无线数据传输单元将目标数据传输至目标终端，其中，无线数据传输单元为基于高载波频率的近距离无线通信单元。
比如，在存储器中确定对应的目标数据后，无线充电装置可以检测其是否与目标终端建立了无线数据传输连接。
若检测到该无线充电装置尚未与该目标终端建立无线数据传输连接，那么该无线充电装置可以执行其它操作。
若检测到该无线充电装置与该目标终端建立了无线数据传输连接，那么该无线充电装置可以将关于电影的目标数据通过无线链路传输给该目标终端。比如在配备了无线充电装置的高铁上，用户将终端放置在该无线充电装置上，该无线充电装置可以与该目标终端建立无线数据传输连接。当二者建立了无线数据传输连接时，该无线充电装置就可以通过无线链路将关于电影A的目标数据传输至该目标终端。
基于高载波频率的近距离无线通信，在发送端设备向接收端设备发送待传输数据的过程中，由于发送端设备和接收端设备之间的对准要求高，数据传输时可能会发生中断，因此本申请实施例的数据传输方法还可以包括：
在所述发送端设备与所述接收端设备之间被中断的近距离无线通信重新恢复之后，所述发送端设备查询记录的传输信息，所述传输信息用于指示所述待传输数据中未完成传输的数据块；
所述发送端设备向所述接收端设备发送所述待传输数据中未完成传输的数据块。
由此，实现发送端设备与接收端设备之间的断点续传，可以避免用户的数据丢失，并且在数据传输中断并重连后继续下载上次未完成下载的数据块，提升用户体验。
在一个实施例中，在所述发送端设备与所述接收端设备之间的近距离无线通信被中断之前，所述方法还可以包括：
所述发送端设备将所述待传输数据分割成数据块。
在一个实施例中，割成多个数据块，使得每个数据块的传输时间小于或等于预设时间。预设时间可为1s。

需要说明的是，该控制指令用于对指定该目标终端进行控制，该控制指令可以包括停止下载指令、开始下载指令、目标数据删除指令、目标数据发送指令等，且该控制指令可以由用户通过指定操作触发。
本申请实施例中，上述目标终端可以是任何具有无线数据传输功能的智能电子设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等。
由上可知，本申请实施例提供的数据传输方法可以接收从目标终端发送的下载请求，下载请求携带数据标识，根据数据标识在存储器中确定对应的目标数据，当检测到无线充电装置与目标终端建立无线数据传输连接时，通过无线数据传输单元将目标数据传输至目标终端，其中，无线数据传输单元为基于高载波频率的近距离无线通信单元。本申请实施例可以在无线充电装置当中预先存储数据，当用户需要下载时，通过无线数据传输单元将目标数据传输至目标终端，因此本实施例可以节省终端的移动通信网络的数据流量。
根据上一实施例的描述，以下将进一步地来说明本申请的数据传输方法。
请参阅图6，图6为本申请实施例提供的另一种数据传输方法的流程示意图，包括以下步骤：
步骤S201，接收从目标终端发送的数据查询请求。
在本实施例中，目标终端和无线充电装置之间可以进行远程通信。终端可以远程发送指令给无线充电装置，该无线充电装置可以对该终端发送的指令进行响应。或者，无线充电装置可以远程发送指令给终端，该终端可以对该无线充电装置发送的指令进行响应。
在一种实施方式中，该无线充电装置和终端可以是均安装有无线数据传输单元的设备。其中，该无线数据传输单元可以是嵌入有极高频(Extremely high frequency，EHF)天线的集成电路(IC)芯片。在安装有该集成电路芯片的设备之间可以利用极高频电磁信号实现非接触式的高速数据传输。例如，无线充电装置为无线充电底座，该无线充电底座上安装有上述集成电路芯片。终端上也安装有上述集成电路芯片。那么，当用户将该终端放置在该无线充电底座上时，该无线充电底座和该终端可以利用极高频电磁信号实现非接触式的高速无线数据传输。
比如，该无线充电底座可以接收从目标终端发送的数据查询请求，该数据查询请求用于查询该无线充电底座当中存储的数据信息，以便用户选择进行下载。
步骤S202，根据数据查询请求以及存储器中存储的数据生成数据标识集合。
其中，上述数据标识集合可以以列表的形式呈现，比如将该无线充电底座当中存储的多媒体数据按照数据类型进行分类，然后生成一个数据列表，该数据列表中包括该无线充电底座当中存储的不同类型的多媒体数据。
在实际使用当中，若目标终端中剩余的存储空间较少，以至于无线充电底座当中存储的一部分数据容量超出了终端的剩余空间，那么这些多媒体数据将无法下载到目标终端当中。比如目标终端剩余容量为2GB，无线充电底座当中存储的电影A为1.8GB，满足终端的剩余容量可以被下载到终端当中，而无线充电底座当中存储的电影B为2.5GB，超过了终端的剩余容量，则电影B将无法被下载到终端当中。因此在一实施例中，数据查询请求可以携带目标终端的剩余容量；
根据数据查询请求以及存储器中存储的数据生成数据标识集合的步骤，可以具体包括：
确定存储器中满足目标终端剩余容量的数据；
获取数据的数据标识以生成数据标识集合。
步骤S203，将数据标识集合发送至目标终端。
在一实施例中，还可以根据数据标识集合当中数据的活跃度先进行排序，再将排序后的数据标识集合发送至目标终端。也即在将数据标识集合发送至目标终端之前，上述方法还可以包括：
获取数据标识集合当中数据的下载频率；
根据下载频率对数据标识集合中的数据标识进行排序。
上述下载频率为在一定预设时间段内数据被下载的频率，可以体现数据的活跃度。在其他实施例当中，还可以根据下载次数来进行排序。可以方便用户查找热度比较高的多媒体文件并下载，提升用户体验。
步骤S204，接收从目标终端发送的下载请求，下载请求携带数据标识。
其中，上述数据可以包括视频、音频、图片、以及文档等多媒体数据，数据标识则可以为多媒体数据的名称，比如电影“XX历险记”。需要说明的是，该数据标识用于唯一标识该多媒体数据，在其他实施例当中，该数据标识还可以为多媒体数据的编号等。
步骤S205，若根据数据标识在存储器中搜索到至少两份对应的备选数据，则获取目标终端的剩余容量。
步骤S206，根据目标终端的剩余容量以及备选数据的数据量，确定对应的目标数据。
比如，数据下载请求为用于指示无线充电装置下载电影A的请求。在接收到该数据下载请求后，无线充电装置可以搜索电影A的可播放多媒体文件。例如，该无线充电装置搜索到电影A的标清版本的可播放多媒体文件、高清版本的可播放多媒体文件以及超清版本的可播放多媒体文件。即，该无线充电装置搜索到电影A的3份对应的备选数据。
在这种情况下，该无线充电装置可以获取每一备选数据的数据量。例如，该无线充电装置获取到电影A的标清版本的可播放多媒体文件的数据量为1GB，电影A的高清版本的可播放多媒体文件的数据量为3GB，电影A的超清版本的可播放多媒体文件的数据量为5GB。
然后，无线充电装置可以获取其存储器当前的剩余容量。例如，该无线充电装置的存储器当前的剩余容量为3.5GB。
之后，无线充电装置可以根据每一备选数据的数据量，以及存储器的剩余容量，从备选数据中选取目标数据，并从网络侧下载该目标数据。
例如，无线充电装置可以将数据量小于存储器的剩余容量的备选数据选取为目标数据。例如，由于电影A的标清版本和高清版本的可播放多媒体文件的数据量均小于存储器的剩余容量，因此无线充电装置可以将电影A的标清版本或高清版本的可播放多媒体文件选取为目标数据。例如，无线充电装置可以将电影A的高清版本的可播放多媒体文件选取为目标数据。
步骤S207,当检测到无线充电装置与目标终端建立无线数据传输连接时，通过无线数据传输单元将目标数据传输至目标终端。
若检测到该无线充电装置与该目标终端建立了无线数据传输连接，那么该无线充电装置可以将关于电影的目标数据通过无线链路传输给该目标终端。比如在配备了无线充电装置的高铁上，用户将终端放置在该无线充电装置上，该无线充电装置可以与该目标终端建立无线数据传输连接。当 二者建立了无线数据传输连接时，该无线充电装置就可以通过无线链路将关于电影A的目标数据传输至该目标终端。
由上可知，本申请实施例可以接收从目标终端发送的数据查询请求，根据数据查询请求以及存储器中存储的数据生成数据标识集合，将数据标识集合发送至目标终端，接收从目标终端发送的下载请求，下载请求携带数据标识，若根据数据标识在存储器中搜索到至少两份对应的备选数据，则获取目标终端的剩余容量，根据目标终端的剩余容量以及备选数据的数据量，确定对应的目标数据，当检测到无线充电装置与目标终端建立无线数据传输连接时，通过无线数据传输单元将目标数据传输至目标终端，本申请实施例可以在无线充电装置当中预先存储数据，当用户需要下载时，通过无线数据传输单元将目标数据传输至目标终端，因此本实施例可以节省终端的移动通信网络的数据流量。
请参阅图7，图7为本申请实施例提供的数据传输方法的场景示意图。
本实施例中，无线充电装置和终端均安装有嵌入极高频天线的集成电路芯片。在安装有该集成电路芯片的设备之间可以利用极高频电磁信号实现非接触式的高速无线数据传输。同时，终端与无线充电装置之间可以进行远程通信。即，终端可以远程发送指令给无线充电装置，该无线充电装置可以对该终端发送的指令进行响应。或者，无线充电装置可以远程发送指令给终端，该终端可以对该无线充电装置发送的指令进行响应。
比如在高铁上，用户想要下载电影“XX历险记”并观看，就可以先通过终端与高铁上的无线充电装置建立连接，用户在文本框中输入关键词“电影XX历险记”，并点击“下载”按钮。在接收到用户输入的信息后，终端可以将该信息转换成下载指令，并将该下载指令发送到无线充电装置。
无线充电装置在接收到终端发送过来的下载指令后，可以根据该下载指令，在存储器搜索电影“XX历险记”的资源，之后，该无线充电装置可以通过无线链路，将存储器中保存的上述影片资源传输至该终端。
