具体实施例
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
在本文中提及的“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
请参考图1，其示出了本申请一个示例性实施例提供的实施环境的环境示意图，该实施环境中包括无线功率发送设备10和无线功率接收设备20。
无线功率发送设备10是指无线充电中用于给用电设备提供功率的设备。在不同的业务场景中，无线功率发送设备10的名称可能有所不同。例如，当无线功率发送设备10是用于给手机、平板电脑、可穿戴设备等便携式电子设备进行无线充电时，无线功率发送设备10可以称为充电器、充电盘、电源适配器、无线充电器等。又例如，当无线功率发送设备10是用于给电动汽车等交通工具进行无线充电时，无线功率发送设备10可以称为充电桩、无线充电桩等。
无线功率接收设备20是指无线充电中用于接收功率的设备，也即用电设备。无线功率接收设备20可以是任何支持无线充电的用电设备，如手机、平板电脑、可穿戴设备、电动汽车等设备，本公开实施例对此不作限定。
在一种可能的实施方式中，无线功率发送设备10和无线功率接收设备20之间的无线充电通信方式包括带内通信或带外通信中的至少一种。其中，带内通信是一种基于无线充电的工作频段进行通信的方式，带外通信是一种采用无线充电的非工作频段进行通信的方式。图1中，带内通信过程中，无线功率发送设备10和无线功率接收设备20基于无线充电的工作频段进行通信；带外通信过程中，无线功率发送设备10和无线功率接收设备20通过带外通信组件，在带外通信组件的工作频段(无线 充电的工作频段以外的频段)进行通信，可选的，该带外通信组件可以是蓝牙芯片、NFC芯片、ZigBee芯片中的至少一种。
在图1的基础上，如图2所示，以无线功率发送设备10和无线功率接收设备20通过蓝牙芯片进行带外通信为例进行说明。
如图2所示，无线功率发送设备10设置有无线功率发送芯片101与第一CPU102相连，第一CPU102与第一蓝牙芯片103相连；无线功率接收设备20设置有无线功率接收芯片201与第二CPU202相连，第二CPU202与第二蓝牙芯片203相连。
带外通信过程中，无线功率接收设备20通过无线功率接收芯片201与第二CPU202进行通信，将需要传输的数据包发送给第二CPU202，由第二CPU202将数据包发送给第二蓝牙芯片203，以便第二蓝牙芯片203通过蓝牙连接(带外通信)将数据包发送给第一蓝牙芯片103。相应的，无线功率发送设备10通过第一蓝牙芯片103接收到无线功率接收设备20带外传输的数据包后，将该数据包发送给第一CPU102，由第一CPU102将数据包发送给无线功率发送芯片101，以便无线功率发送芯片101对该数据包进行解析处理。类似的，无线功率发送设备10可以通过类似的过程对无线功率接收设备20发送的数据包进行反馈，本实施例在此不再赘述。
请参考图3，其示出了本申请一个示例性实施例提供的无线充电通信方法的流程图。本实施例以该方法用于图1所示的实施环境为例进行说明，该方法包括：
步骤301，若无线充电过程中需传输紧急数据，无线功率接收设备则采用带内通信方式向无线功率发送设备发送数据包。
在一种可能的实施方式中，无线功率接收设备判断设备需传输紧急数据还是非紧急数据，若需传输紧急数据，则执行步骤301；若需传输非紧急数据，则执行步骤302。可选的，紧急数据的传输时延要求高于非紧急数据的传输时延要求，即相较于非紧急数据，紧急数据需要更快传输至无线功率发送设备，以便无线功率发送设备尽快处理。
可选的，带内通信在发射端(无线功率发送设备)与接收端(无线功率接收设备)之间有两种通信链路。其中，从接收端到发射端的通信采用幅移键控(Amplitude Shift Keying，ASK)调制方式，从发射端到接收端的通信采用频移键控(Frequency Shift Keying，FSK)调制方式。
在需传输紧急数据时，无线功率接收设备根据当前所处的需传输紧急数据的情况生成相应的数据包，并采用ASK调制方式向无线功率发送设备发送数据包，指示无线功率发送设备对接收到的数据包进行处理。
步骤302，若无线充电过程中需传输非紧急数据，无线功率接收设备则采用带外通信方式向无线功率发送设备发送数据包。
非紧急数据即排除紧急数据的传输数据，非紧急数据的传输时延要求低于紧急数据的传输时延要求，无线功率接收设备可通过带外通信进行数据包的传输，带外通信相较于带内通信的传输时延更长，但是其通信质量高于带内通信，因此在传输非紧急数据时，无线功率接收设备采用带外通信方式发送数据包，以此保障数据包的传输质量，提高无线功率发送设备对数据包的解析成功率。
其中，当无线功率接收设备确定采用带外通信时，还需要开启带外通信功能。在一种可能的应用场景中，当手机(无线功率接收设备)与无线充电板(无线功率发送设备)之间需要进行带外通信时，且带外通信方式为蓝牙方式，则手机界面会出现提示框，提示框用于提示用户手动开启蓝牙功能；或者，手机后台进行蓝牙的自动开启，从而实现手机与无线充电板之间的带外通信。
步骤303，无线功率发送设备接收无线功率接收设备发送的数据包。
在无线充电过程中，无线功率发送设备开启带内通信模式和带外通信模式。不同于相关技术中，无线功率发送设备在无线充电过程中，仅能够通过带内通信方式接收无线功率接收设备发送的数据包，本申请实施例中，无线功率发送设备同时开启带内通信模式和带外通信模式，确保无线功率接收设备通过带内通信或带外通信发送的数据包均能够被正常接收。
可选的，进入无线充电过程前(比如在识别配置阶段)，无线功率发送设备检测无线功率接收设备是否支持带外通信，并在支持时，在无线充电过程中同时开启带内通信模式和带外通信模式；否则，仅开启带内通信模式。
步骤304，无线功率发送设备确定发送数据包时采用的通信方式。
其中，通信方式包括带内通信方式和带外通信方式。可选的，无线功率发送设备接收无线功率接收设备采用带内通信方式发送的数据包，和/或，接收无线功率接收设备采用带外通信方式发送的数据包。
在一种可能的实施方式中，无线功率发送设备在接收到数据包后，确定无线功率接收设备发送数据包时采用的通信方式，无线功率接收设备在需传输紧急数据时发送的数据包确定为采用带内通信方式，无线功率接收设备在需传输非紧急数据时发送的数据包确定为采用带外通信方式。
步骤305，无线功率发送设备优先处理采用带内通信方式发送的数据包。
可选的，为了提高无线功率发送设备对紧急数据的处理速度，以便尽快解除无线功率接收设备的紧急状态，采用不同通信方式发送的数据包具有不同的处理优先级，无线功率发送设备即根据处理优先级对数据包进行处理，而非按照接收顺序依次处理。
在一种可能的实施方式中，无线功率发送设备接收到通过带内通信方式发送的数据包和通过带外通信方式发送的数据包，其中，通过带内通信方式发送的数据包的处理优先级高于通过带外通信方式发送的数据包的处理优先级，即当无线功率发送设备接收到通过带内通信方式发送的数据包时，优先处理通过带内通信方式发送的数据包。
综上所述，本公开实施例中，若无线充电过程中需传输紧急数据，则采用带内通信方式向无线功率发送设备发送数据包；若无线充电过程中需传输非紧急数据，则采用带外通信方式向无线功率发送设备发送数据包；相较于相关技术中采用单一的带内通信方式，采用本申请实施例提供的方法，在需传输非紧急数据时，采用通信质量较好的带外通信方 式发送对传输时延要求较低的数据包，有助于提高数据包的解调成功率，而在需传输紧急数据时，采用带内通信方式发送对传输时延要求较高的数据包，确保无线功率发送设备能够及时对需传输紧急数据情况下的数据包进行处理。
为了进一步提高紧急数据的处理效率，针对无线功率接收设备生成数据包的过程，在一种可能的实施方式中，在无线充电过程中需传输紧急数据时，无线功率接收设备优先生成紧急数据对应的数据包，而对于需传输的非紧急数据，无线功率接收设备则在生成紧急数据对应的数据包后，生成非紧急数据对应的数据包。
在一种可能的实施方式中，无线充电过程中，无线功率接收设备在如下至少一种紧急状态下确定需要传输紧急数据：CEP中包含的控制误差值大于误差阈值、无线功率接收设备的输出电流大于第一阈值、无线功率接收设备的设备温度大于第二阈值、无线功率接收设备中计时器的计时器状态为到时状态。下面采用示意性的实施例对上述各种需传输紧急数据的情况进行说明。
请参考图4，其示出了本申请另一个示例性实施例提供的无线充电通信方法的流程图，此实施例以与CEP相关的紧急状态为例进行说明。该方法包括：
步骤401，无线功率接收设备获取CEP中包含的控制误差值。
其中，CEP用于指示无线功率发送设备调节电压、电流和工作频率中的至少一种，CEP包含有控制误差值，该控制误差值的范围在-128至+127之间，即控制误差值具有正负性。
相关技术中，无线充电过程中，无线功率接收设备按照预定时间间隔(比如250ms)通过带内通信方式向无线功率发送设备发送CEP，由无线功率发送设备接收CEP并解调出其中包含的控制误差值。当控制误差值为正数时，无线功率发送设备提高初级线圈的电流(初级线圈位于无线功率发送设备内)，或，提高自身的电压，或，当无线功率发送设 备的电压达到最大值时，降低自身的工作频率。当控制误差值为负数时，无线功率发送设备降低初级线圈的电流，或，提高自身的工作频率，或，当无线功率发送设备的工作频率达到最大值时，降低自身的电压。
而在本发明的实施例中，无线功率接收设备在传输CEP之前需要对CEP的控制误差值进行检测，判断控制误差值是否大于误差阈值，若控制误差值大于误差阈值，则执行步骤402，若控制误差值小于误差阈值，则执行步骤404。
可选的，该误差阈值为正值，且无线功率接收设备比较控制误差值与误差阈值时，将控制误差值的绝对值与误差阈值进行比较。
步骤402，若控制误差值大于误差阈值，则无线功率接收设备确定无线充电过程中需传输紧急数据，并采用带内通信方式向无线功率发送设备发送CEP。
若控制误差值大于误差阈值，表明无线功率发送设备处的调整量较大(需要进行较大电流、电压或工作频率调整)，若无线功率发送设备调整过慢，可能会导致无线功率接收设备受损，因此在控制误差值大于误差阈值的情况下，无线功率接收设备采用带内通信方式发送CEP，使得无线功率接收设备尽快地将CEP发送给无线功率发送设备，从而确保无线功率发送设备能够及时对需传输紧急数据情况下的CEP进行处理。
在一个示意性的例子中，控制误差值为-90，当检测到控制误差值的绝对值大于误差阈值80时，无线功率接收设备确定无线充电过程中需传输紧急数据，并采用带内通信方式向无线功率发送设备发送CEP。
步骤403，无线功率发送设备接收无线功率接收设备采用带内通信方式发送的CEP。
由于无线功率发送设备同时开启带内通信与带外通信，因此当无线功率接收设备通过带内通信方式发送CEP时，无线功率发送设备能够及时地在带内通信方式下接收CEP。
步骤404，若控制误差值小于误差阈值，则无线功率接收设备确定无线充电过程中需传输非紧急数据，并采用带外通信方式向无线功率发 送设备发送CEP。
若控制误差值小于误差阈值，表明无线功率发送设备处的调整量较小，即便无线功率发送设备调整较慢，也不会对无线功率接收设备造成较大影响。因此在无线充电过程中需传输非紧急数据时，无线功率接收设备采用通信质量较好但是传输延迟较高的带外通信方式发送CEP，以此保障CEP的传输质量，提高无线功率发送设备对CEP的解析成功率。
在一个示意性的例子中，控制误差值为+10，当检测到控制误差值的绝对值小于误差阈值80时，无线功率接收设备确定无线充电过程中需传输非紧急数据，并采用带外通信方式向无线功率发送设备发送CEP。
步骤405，无线功率发送设备接收无线功率接收设备采用带外通信方式发送的CEP。
同样的，由于无线功率发送设备同时开启带内通信与带外通信，因此当无线功率接收设备通过带外通信方式发送CEP时，无线功率发送设备能够及时地在带外通信方式下接收CEP。
步骤406，无线功率发送设备优先处理通过带内通信方式发送的CEP。
相应的，无线功率发送设备获取CEP，并根据CEP中的控制误差数调节电压、电流和工作频率中的至少一种。
在一种可能的实施方式中，无线功率发送设备接收到通过带内通信方式发送的CEP和通过带外通信方式发送的CEP，其中，通过带内通信方式发送的CEP的处理优先级高于通过带外通信方式发送的CEP的处理优先级，即当无线功率发送设备接收到通过带内通信方式发送的CEP时，优先处理通过带内通信方式发送的CEP。
本实施例中，无线充电过程中，无线功率接收设备获取CEP中包含的控制误差值，当控制误差值大于误差阈值时确定无线充电过程中需传输紧急数据，并采用带内通信方式向无线功率发送设备发送CEP；当控制误差值小于误差阈值时确定无线充电过程中需传输非紧急数据，并采用带外通信方式向无线功率发送设备发送CEP；相较于相关技术中采用单一的带内通信方式发送CEP，采用本申请实施例提供的方法，在线充 电过程中需传输紧急数据时，采用通信质量较好的带外通信方式发送对传输时延要求较低的CEP，有助于提高CEP的解调成功率，而线充电过程中需传输非时紧急数据，采用带内通信方式发送对传输时延要求较高的CEP，确保无线功率发送设备能够及时对需传输紧急数据情况下的CEP进行处理。
请参考图5，其示出了本申请另一个示例性实施例提供的无线充电通信方法的流程图，此实施例以与输出电流相关的紧急状态为例进行说明。该方法包括：
步骤501，无线功率接收设备获取无线功率接收设备的输出电流。
在一种可能的实施方式中，无线功率接收设备的输出电流异常可能与电路短路与接收功率过大有关，若在输出电流异常的情况下继续进行无线充电，可能会造成无线功率接收设备受损，因此在无线充电过程中，无线功率接收设备持续获取输出电流，并检测输出电流是否大于第一阈值，若大于，则确定输出电流异常，并执行步骤502。
步骤502，若输出电流大于第一阈值，则无线功率接收设备确定无线充电过程中需传输紧急数据，并采用带内通信方式向无线功率发送设备发送第一数据包。
为了保障无线功率发送设备安全，若输出电流大于第一阈值，无线功率接收设备确定当前无线充电过程中需传输紧急数据，并选择采用传输时延较低的带内通信方式向无线功率发送设备发送第一数据包，而非采用传输时延较高的带外通信方式。
其中，在需传输紧急数据时，第一数据包用于指示停止功率传输，该第一数据包可以是基于QI协议下的终止传输(End Power Transfer，EPT)包，本实施例对此不做限定。
在一个示意性的例子中，无线功率接收设备获取到当前的输出电流为2A，由于当前的输出电流大于第一阈值1A时，因此无线功率接收设备确定无线充电过程中需传输紧急数据，并采用带内通信方式向无线功率发送设备发送EPT包。
步骤503，无线功率发送设备接收无线功率接收设备采用带内通信方式发送的第一数据包。
由于无线功率发送设备同时开启带内通信与带外通信，因此当无线功率接收设备通过带内通信方式发送第一数据包时，无线功率发送设备能够及时地在带内通信方式下接收第一数据包。
步骤504，无线功率发送设备对第一数据包进行解调处理。
在一种可能的实施方式中，在需传输紧急数据时，无线功率发送设备获取第一数据包，并根据第一数据包停止功率传输。当无线功率接收设备的输出电流处于正常范围内时，无线功率接收设备与无线功率发送设备重新建立无线充电通信，并进行功率传输。
本实施例中，无线充电过程中，无线功率接收设备获取自身的输出电流，并在输出电流大于第一阈值时确定无线充电过程中需传输紧急数据，从而采用传输时延较低的带内通信方式向无线功率发送设备发送第一数据包，确保无线功率发送设备能够及时根据第一数据包停止功率传输，避免继续功率传输对无线功率接收设备造成损害。
请参考图6，其示出了本申请另一个示例性实施例提供的无线充电通信方法的流程图，此实施例以与设备温度相关的紧急状态为例进行说明。该方法包括：
步骤601，无线功率接收设备获取无线功率接收设备的设备温度。
由于设备在充电过程中会产生热量，且当设备温度过高时，继续充电可能会造成设备损坏，因此，无线功率接收设备在无线充电过程中持续获取设备温度，并检测设备温度是否大于第二阈值，若大于，则确定设备温度过高，并执行步骤602。
如图2所示结构中，在一种可能的实施方式中，当无线功率接收设备需要获取设备温度时，无线功率接收芯片201向第二CPU202发送获取设备温度的请求，第二CPU202接收到该请求后将当前设备温度反馈给无线功率接收芯片201，无线功率接收芯片201将所获取的设备温度与第二阈值进行比较，判断无线充电过程中是否需传输紧急数据，若设 备温度高于第二阈值，则确定无线充电过程中需传输紧急数据。
步骤602，若设备温度大于第二阈值，则无线功率接收设备确定无线充电过程中需传输紧急数据，并采用带内通信方式向无线功率发送设备发送第二数据包。
为了保障无线功率发送设备安全，若设备温度大于第二阈值，无线功率接收设备确定当前无线充电过程中需传输紧急数据，并选择传输时延较低的带内通信方式向无线功率发送设备发送第二数据包，而非采用传输时延较高的带外通信方式。
其中，在需传输紧急数据时，第二数据包用于指示停止功率传输，该第二数据包可以是EPT包，本实施例对此不做限定。
在一个示意性的例子中，无线功率接收设备获取到当前的设备温度为60摄氏度，由于当前的设备温度大于第二阈值50摄氏度，因此无线功率接收设备确定无线充电过程中需传输紧急数据，并采用带内通信方式向无线功率发送设备发送EPT包。
步骤603，无线功率发送设备接收无线功率接收设备采用带内通信方式发送的第二数据包。
由于无线功率发送设备同时开启带内通信与带外通信，因此当无线功率接收设备通过带内通信方式发送第二数据包时，无线功率发送设备能够及时地在带内通信方式下接收第二数据包。
步骤604，无线功率发送设备对第二数据包进行解调处理。
在一种可能的实施方式中，在需传输紧急数据时，无线功率发送设备获取第二数据包，并根据第二数据包停止功率传输。当无线功率接收设备的设备温度处于正常范围内时，无线功率接收设备与无线功率发送设备重新建立无线充电通信，并进行功率传输。
本实施例中，无线充电过程中，无线功率接收设备获取自身的设备温度，并在设备温度大于第二阈值时确定无线充电过程中需传输紧急数据，从而采用传输时延较低的带内通信方式向无线功率发送设备发送第二数据包，确保无线功率发送设备能够及时根据第二数据包停止功率传输，避免继续功率传输对无线功率接收设备造成损害。
请参考图7，其示出了本申请另一个示例性实施例提供的无线充电通信方法的流程图，此实施例以与计时器状态相关的紧急状态为例进行说明。该方法包括：
步骤701，无线功率接收设备获取无线功率接收设备中计时器的计时器状态。
其中，该计时器用于在达到计时器时长时，触发无线功率接收设备向无线功率发送设备发送第三数据包，该第三数据包用于指示无线功率发送设备调整传输功率、调整传输电流、调整传输电压或停止功率传输等等，本申请实施例并不对第三数据包的具体用途进行限定。
在一种可能的实施方式中，第一计时器的计时器时长为第一时长，第一计时器用于在达到第一时长时，触发无线功率接收设备向无线功率发送设备发送EPT包，从而停止功率传输；或者，第二计数器的计时器时长为第二时长，第二计时器用于在达到第二时长时，触发无线功率接收设备向无线功率发送设备发送CEP，从而指示无线功率发送设备降低传输功率。
可选的，计时器状态包括到时状态(到达计时器时长)和未到时状态(未达到计时器时长)，当检测到计时器状态为到时状态时，无线功率接收设备执行步骤702；当检测到计时器状态为未到时状态时，无线功率接收设备则继续检测计时器状态。
步骤702，若计时器状态为到时状态，则无线功率接收设备确定无线充电过程中需传输紧急数据，并采用带内通信方式向无线功率发送设备发送第三数据包。
为了使无线功率发送设备能够尽快处理第三数据包，当计时器处于到时状态时，无线功率接收设备通过传输时延较低的带内通信方式发送第三数据包，而非采用传输时延较高的带外通信方式。
可选的，采用带内通信方式向无线功率发送设备发送第三数据包后，无线功率接收设备关闭计时器。
步骤703，无线功率发送设备接收无线功率接收设备采用带内通信 方式发送的第三数据包。
由于无线功率发送设备同时开启带内通信与带外通信，因此当无线功率接收设备通过带内通信方式发送第三数据包时，无线功率发送设备能够及时地在带内通信方式下接收第三数据包。
步骤704，无线功率发送设备对第三数据包进行解调处理。
在一种可能的实施方式中，若第三数据包(EPT包)是无线功率发送设备在第一计时器处于到时状态时发送，无线功率发送设备则根据第三数据包停止功率传输；若第三数据包(CEP)是无线功率发送设备在第二计时器处于到时状态时发送，无线功率发送设备则根据第三数据包调整电压、电流或工作频率中的至少一种，以降低传输功率。
本实施例中，无线充电过程中，无线功率接收设备获取计时器的计时器状态，并在计时器状态为到时状态时确定无线充电过程中需传输紧急数据，从而采用传世时延较低的带内通信方式向无线功率发送设备发送第三数据包，确保无线功率发送设备能够及时对需传输紧急数据情况下的第三数据包进行处理。
相关技术中，采用带内通信时，无线功率发送设备若在预定时长内(比如1.25s)未接收到无线功率接收设备发送的数据包，无线功率发送设备将停止功率输出，以此降低功耗。
而在本申请各个实施例中，由于设备之间存在带内和带外两种通信方式，因此带内通信与带外通信具有各自的延时机制。在一种可能的实施方式中，若在第一预定时长内(比如1.25s)未接收到采用带内通信方式发送的数据包，无线功率发送设备则确定带内通信失败；若在第二预定时长内(比如3s)未接收到采用带外通信方式发送的数据包，无线功率发送设备则确定带外通信失败。可选的，第一预定时长小于第二预定时长。此外，当带内通信失败且带外通信失败时，无线功率发送设备停止功率输出，以此降低功耗。
需要说明的是，上述各个实施例中，以无线功率发送设备为执行主 体的步骤可以实现成为无线功率发送设备侧的无线充电通信方法，以无线功率接收设备为执行主体的步骤可以实现成为无线功率接收设备侧的无线充电通信方法，本实施例在此不再赘述。
