具体实施方式
下面将结合附图对本申请的技术方案进行清楚、完整地描述，显然，所描述的实施方式是本申请一部分实施方式，而不是全部的实施方式。基于本申请中的实施方式，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施方式，都属于本申请保护的范围。此外，下面所描述的本申请不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
在无线充电场景中，在进行无线充电时，待充电设备通常需要先确定与无线充电设备之间的充电协议，然后，通过该充电协议进行无线充电。但是，传统技术下，通常难以准确且快速地识别充电协议。
例如，接收端实时检测接收的电信号的当前工作频率，以F1频率数值为基准频率，当检测到当前工作频率由F1变化到F2时，确定通过目标充电协议进行无线充电。但是，采用这种方式，仅根据频率是否从F1变化到了F2进行协议识别，通常仅能应用于单一充电协议的场景，在存在多种充电协议时，通常难以快速且准确地识别充电协议。
基于上述相关技术存在的缺陷，本申请实施例中提供了一种协议识别的方法、装置、电子设备、存储介质及程序产品，旨在无线充电时，快速且准确地识别充电协议。
本申请实施例中提供了一种协议识别的方法，该方法可应用于电子设备，本申请对于电子设备的类型不作限制，其可以是任何适于实施的设备类型，例如终端设备以及服务器等，本申请对此不再赘述。
参阅图1所示，为一种协议识别的场景示意图。图1中所示的场景中，包含待充电设备以及无线充电设备。无线充电设备中包含逆变器以及发射器。待充电设备中包含整流电路以及接收器。无线充电设备可以通过逆变器为发射器通电。发射器被通电后，会产生变化磁场。接收器由该变化磁场激发出电信号，并可以通过整流电路对该电信号进行后续处理，从而实现待充电设备与无线充电设备之间的能量的无线传输。在这个过程中，待充电设备可以根据电信号的变化，识别当前的目标充电协议，进而可以进行无线充电。
下面结合图1和图2，对本申请实施例中一种协议识别的方法进行说明，参阅图2所示，为本申请实施例中协议识别的方法的流程图，应用于图1中的待充电设备，下面结合图2对该方法进行说明，该方法的具体实施流程如下：
步骤201：确定接收到无线充电设备发送的电信号时，获得电信号的目标信号参数的参数值序列。
一种实施方式中，待充电设备与无线充电设备接触后，无线充电通过发射器产生变化磁场。待充电设备获得接收器被该变化磁场激发的电信号。待充电设备对一段时间内的电信号进行采样，可以获得目标信号参数的多个参数值，并获得各参数值组成的参数值序列。
其中，目标信号参数包括以下至少一个：频率以及电压，实际应用中，目标信号参数可以根据实际应用场景进行设置，如，目标信号参数还可以为电流。在此不作限制。
进一步地，若目标信号参数的各参数值符合波形曲线规则，则根据各参数值中的峰值，生成参数值序列。
其中，波形曲线规则可以根据参数值的周期性变化设置，如，电压曲线为正弦波，则确定符合波形曲线规则。
这样，就可以获得激发的电信号的电压序列或者频率序列。
步骤202：根据参数值序列中符合设定筛选条件的目标参数值的类别数量，确定对应的目标充电协议，或者，根据基于参数值序列生成的参数编码，确定对应的目标充电协议。
一种实施方式中，执行步骤202时，可以采用以下任一方式：
方式一：根据参数值序列中符合设定筛选条件的目标参数值的类别数量，确定对应的目标充电协议。
可选的，设定筛选条件可以为被指定参数集合。不同的目标参数值可以对应不同的类别，或者，预先设置各类别对应的参数值区间，从而可以确定各目标参数值各自所属的参数值区间对应的类别，并统计类别数量。
一种实施方式中，从参数值序列中，筛选出被指定参数集合包含的目标参数值；确定筛选出的目标参数值的类别数量；将类别数量对应的充电协议，确定为目标充电协议。
其中，可以预先建立类别数量与充电协议之间的对应关系，从而可以根据该对应关系，确定电信号的类别数量对应的目标充电协议。
在充电协议仅包含两种时，若类别数量不低于设定数量，则可以确定目标充电协议为第一充电协议，否则，确定目标充电协议为第二充电协议。
例如，第一充电协议可以为电源事物联盟(Power Matters Alliance，PMA)协议，第二充电协议可以为qi协议。
例如，若目标信号参数为频率，设定数量可以不低于3，若目标信号参数为电压，则设定数量可以不低于2，实际应用中，设定数量可以根据实际应用场景对设定数量进行设置，在此不作限制。
为提高基于目标信号参数传递的信息的丰富性，指定参数集合中的参数值的类型数量不低于设定数量，且指定参数集合中任意两个相邻参数值之间的差值可以大于X，X为正数。
下面结合图3进行示例说明，参阅图3所示，为一种频率信号的示例图。图3中，频率依次为F1、F2以及F3。假设设定数量为3，且指定参数集合中包含F1、F2、F3三种频率。当手机(即待充电设备)放在无线底座(即无线充电设备)上之后，无线底座提供初始工作能量，并不断改变自身的工作频率，使其包含F1、F2、F3。手机接收到电信号后，确定该电信号包含F1、F2、F3的频率序列(即参数值序列)。由于参数值序列与指定参数集合均包含F1、F2、F3，因此，类别数量为3＝设定数量。
下面结合图4，对方式一进行示例说明。参阅图4所示，为一种基于频率的协议识别的方法的流程图，该方法的流程包括：
S401：无线充电设备对电信号的频率进行调控，并发送调控后的电信号。
S402：待充电设备解析接收的电信号，获得包含多个频率值的参数值序列。
S403：待充电设备筛选出参数值序列中被指定参数集合包含的目标参数值。
S404：待充电设备判断目标参数值的类别数量是否高于设定数量，若是，则执行S405，否则，执行S406。
S405：待充电设备确定目标充电协议为第一充电协议。
S406：待充电设备确定目标充电协议为第二充电协议。
这样，可以根据电信号的频率的类型数量，准确识别充电协议，检测方式更加可靠，提高了协议识别的准确性，以及不需要考虑各类型频率的排序，实现方式更加简单。
方式二：根据基于参数值序列生成的参数编码，确定对应的目标充电协议。
一种实施方式中，根据参数值与编码值之间的对应关系，以及参数值序列中的各参数值，获得参数值序列对应的参数编码；将参数编码对应的充电协议，确定为目标充电协议。
其中，可以预先建立参数值与编码值之间的对应关系，以进行编码，并可以预先建立参数编码与充电协议之间的对应关系，以识别目标充电协议。
在充电协议仅为两种时，若参数编码为目标编码，则可以确定目标充电协议为第一充电协议，否则，确定目标充电协议为第二充电协议。
可选的，目标编码可以对应至少三种参数值。其中，可以包括以下多种情况：
第一种情况为：参数值序列为电压值序列，则可以预先建立电压值与编码值之间的对应关系，进而可以获得电压值序列中各电压值对应的编码值，以及基于各编码值，确定参数编码。
其中，在目标信号参数为电压的情况下，目标信号参数的参数值由无线充电设备的逆变器的输入电压决定。例如，图1中，无线充电设备可以调整逆变器的输入电压V-AB，从而改变待充电设备的电压值序列。
参阅图5所示，为一种电压信号的曲线示意图。由于图5中，电压信号为波形图，因此，基于图5中的各电压峰值即V1、V2、V3以及V4，生成对应的电压值序列。V1、V2、V3以及V4各自对应的编码值依次可以为：1、2、3以及4，则电压值序列对应的参数编码可以为1234。
同理，参阅图6所示，为另一种电压信号的曲线示意图。可以基于图6中的各电压峰值即V1、V2、V3以及V4，生成对应的电压值序列。电压值序列对应的参数编码可以为1234321。
这样，就可以通过调整逆变器的输入电压，实现无线底座发送能量的强弱控制，形成信息的编码。
进一步地，逆变器还可以通过开关时间对输入电压进行调整，即通过控制逆变器的开关的相位角θ，实现移相控制，使得在V-AB上产生特殊的电压波形，随着相位角θ的变化，可以实现信息编码与控制。在接收端输出电压V-CD会对应不同的相位角θ产生不同的电压值。如，V1、V2、V3、V4。
参阅图7所示，为一种电压输入输出的示意图。包括四个坐标图，横坐标均为时间。第一坐标图和第二坐标图表示图1中逆变器的各开关的开关时间。第三坐标图表示逆变器的输入电压V-AB，第四坐标图为输出电压V-CD，在相位角θ固定时，输出电压V-CD不变，例如，输出电压V-CD为V1，在相位角θ变化时，输入电压V-AB变化，输出电压V-CD也会随之变化。
参阅图8所示，为一种基于电压的协议识别的方法的流程图，该方法的流程包括：
S801：无线充电设备对电信号的电压进行调控，并发送调控后的电信号。
S802：待充电设备对接收的电信号进行解析，获得包含多个电压值的参数值序列。
S803：待充电设备基于参数值序列生成的参数编码。
S804：待充电设备判断参数编码是否为目标编码，若是，则执行S805，否则，执行S806。
S805：待充电设备确定目标充电协议为第一充电协议。
S806：待充电设备确定目标充电协议为第二充电协议。
这样，就可以通过调整逆变器的输入电压，或者调整逆变器的开关时间，控制接收器的电压值序列，由于电压值的调节范围广，可以灵活改变的，且可以为任意值，因此，编码方式多样化，可以实现四进制、八进制等多种编码方式，编码内容丰富，携带更多的内容信息，编码内容量大，利于无线接收端获取更多的信息，可以减少信息交互的时间。
进一步地，目标信号参数还可以为电流，参数值序列为电流值序列，则可以预先建立电流值与编码值之间的对应关系，进而可以获得电流值序列中各电流值对应的编码值，以及基于各编码值，确定参数编码。可以基于与电压值编码相似的原理，对电流值编码，在此不做赘述。
第二种情况为：参数值序列为频率值序列，则可以预先建立频率值与编码值之间的对应关系，进而可以获得频率值序列中各频率值对应的编码值，以及基于各编码值，确定参数编码。
可选的，可以直接提取电信号的多个频率值，还可以基于参考频率值，对电信号进行解析，获得各频率值。进一步地，还可以确定各频率值与参考频率的参考频率值的差值，并可以根据各差值对应的编码值，获得参数编码。参考频率还可以称为基准频率。例如，待充电设备的芯片中也存储有该参考频率值，并以该参考频率值为参考，检测频率变化，以快速实现参数编码。
参阅图9所示，为一种参考频率的示例图。图9中，参考频率值可以表示为Fref。参阅图10所示，为一种电信号频率的示例图。图10中，电信号的频率值依次为：F1、F2、Fref、F3以及F4。
参阅图11所示，为一种基于频率编码的协议识别的方法的流程图，该方法的流程包括：
S1101：无线充电设备对电信号的频率进行调控，并发送调控后的电信号。
S1102：待充电设备对接收的电信号进行解析，获得包含多个频率值的参数值序列。
S1103：待充电设备基于参数值序列生成的参数编码。
S1104：待充电设备判断参数编码是否为目标编码，若是，则执行S1105，否则，执行S1106。
S1105：待充电设备确定目标充电协议为第一充电协议。
S1106：待充电设备确定目标充电协议为第二充电协议。
这样，无线充电设备可以在基准频率Fref的基础上改变工作频率，实现在能量传输的过程中信息传递，由于频率值的调节范围广，可以灵活改变的，且可以为任意值，因此，编码方式多样化，可以实现四进制、八进制等多种编码方式，编码内容丰富，携带更多的内容信息，编码内容量大，利于无线接收端获取更多的信息，可以减少信息交互的时间。
进一步地，还可以通过目标充电协议，向无线充电设备发送应答信息，以通过目标充电协议进行无线充电。
一种实施方式中，在目标充电协议为第一充电协议的情况下，通过第一充电协议，向无线充电设备发送应答信息；在目标充电协议为第二充电协议的情况下，通过第二充电协议，向无线充电设备发送应答信息。
进一步地，还可以确定接收到无线充电设备发送的新的电信号时，根据新的电信号对应的类别数量，确定对应的交互信息，或者，根据新的电信号对应的参数编码，确定对应的交互信息。
一种实施方式中，在确定接收到无线充电设备发送的新的电信号时，基于新的电信号，获得目标信号参数的新的参数值序列；根据参数值与编码值之间的对应关系，以及新的参数值序列对应的参数编码，并根据参数编码与信息之间的对应关系，获得新的参数编码对应的交互信息，同理，还可以获得类别数量对应的交互信息，在此不做赘述。
进一步地，待充电设备也可以采用与传输交互详细相似的原理，向无线充电设备返回传输信息，在此不做赘述。
这样，不仅可以在识别充电协议的初始阶段，基于电信号以及参数编码进行信息的传输以及解析，还可以在进入充电状态后，也通过该方式向接收端传递信息，以实现与无线充电设备之间的信息交互。
本申请实施例中，通过目标信号参数的类别数量或者参数编码，确定对应的目标充电协议，可以携带更丰富的信息，可以应用于存在多种充电协议的场景的协议识别，可以提高协议识别的效率以及准确性。

显示单元1340可用于显示由用户输入的信息或提供给用户的信息以及电子设备1300的各种菜单等，本申请实施例中主要用于显示电子设备1300中各应用的显示界面以及显示界面中显示的文本、图片等对象。显示单元1340可以包括显示面板1341。显示面板1341可以采用液晶显示屏(Liquid Crystal Display，LCD)、有机发光二极管(Organic Light-Emitting Diode，OLED)等形式来配置。
输入单元1350可用于接收用户输入的数字或字符等信息。输入单元1350可包括触控面板1351以及其他输入设备1352。其中，触控面板1351，也称为触摸屏，可收集用户在其上或附近的触摸操作(比如用户使用手指、触摸笔等任何适合的物体或附件在触控面板1351上或在触控面板1351附近的操作)。
具体的，触控面板1351可以检测用户的触摸操作，并检测触摸操作带来的信号，将这些信号转换成触点坐标，发送给处理器1310，并接收处理器1310发来的命令并加以执行。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型实现触控面板1351。其他输入设备1352可以包括但不限于物理键盘、功能键(比如音量控制按键、开关机按键等)、轨迹球、鼠标、操作杆等中的一种或多种。
当然，触控面板1351可覆盖显示面板1341，当触控面板1351检测到在其上或附近的触摸操作后，传送给处理器1310以确定触摸事件的类型，随后处理器1310根据触摸事件的类型在显示面板1341上提供相应的视觉输出。虽然在图13中，触控面板1351与显示面板1341是作为两个独立的部件来实现电子设备1300的输入和输出功能，但是在某些实施例中，可以将触控面板1351与显示面板1341集成而实现电子设备1300的输入和输出功能。
电子设备1300还可包括一个或多个传感器，例如压力传感器、重力加速度传感器、接近光传感器等。当然，根据具体应用中的需要，上述电子设备1300还可以包括摄像头等其它部件，由于这些部件不是本申请实施例中重点使用的部件，因此，在图13中没有示出，且不再详述。
本领域技术人员可以理解，图13仅仅是电子设备的举例，并不构成对电子设备的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件。
为了描述的方便，以上各部分按照功能划分为各模块(或单元)分别描述。当然，在实施本申请时可以把各模块(或单元)的功能在同一个或多个软件或硬件中实现。
