具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述。
本公开实施例提供一种信号切换方法，参照图1所示，该方法包括以下步骤：
步骤101、若检测到终端通过转接设备与至少两个外接设备建立连接，则识别至少两个外接设备的传输接口的通信通道。
其中，转接设备通过终端的传输接口与终端连接。
具体的，步骤101若检测到终端通过转接设备与至少两个外接设备建立连接，则识别至少两个外接设备的传输接口的通信通道可以由终端来实现。其中，转接设备是一种连接系统，转接设备一端具有一个接口，可以与终端的传输接口进行匹配连接，另一端具有多个接口，可以连接多个外接设备，转接设备具有能够用于切换终端传输接口的工作模式的切换电路；终端也具有与转接设备的切换电路工作功能不相同的用于切换终端传输接口的工作模式的切换电路，例如终端可以是设置了切换电路的手机、平板电脑等移动设备，终端的传输接口可以是USB Type-C接口；外接设备可以是能够通过转接设备与终端进行连接通信的设备，例如可以是充电器、耳机、音响等设备。
步骤102、根据至少两个外接设备的传输接口的通信通道，判断是否使用第一切换电路或者第二切换电路切换终端的传输接口的工作模式。
其中，第一切换电路设置在终端中，第二切换电路设置在转接设备中。
具体的，步骤102根据至少两个外接设备的传输接口的通信通道，判断是否使用第一切换电路或者第二切换电路切换终端的传输接口的工作模式可以由终端来实现。终端对通过转接设备连接的至少两个外接设备的传输接口的通信通道进行识别分析，根据分析结果确定是否使用第一切换电路或者第二切换电路对终端传输接口的工作模式进行切换，根据具体应用场景保证至少两个外接设备能正常工作。
本公开的实施例所提供的信号切换方法，当检测到终端通过转接设备与至少两个外接设备建立连接时，识别至少两个外接设备的传输接口的通信通道，然后根据至少两个外接设备的传输接口的通信通道，判断是否使用第一切换电路或者第二切换电路切换终端的传输接口的工作模式；这样，终端可以通过转接设备同时连接至少两个外接设备，解决了现有USB Type-C接口的终端中只能同时连接一个外接设备的问题，实现了可以同时连接至少两个外接设备，进而提高了用户的体验效果。
本公开实施例提供一种信号切换方法，参照图2所示，该方法包括以下步骤：
步骤201、若检测到终端通过转接设备与至少两个外接设备建立连接，则终端识别至少两个外接设备的传输接口的通信通道。
其中，转接设备通过终端的传输接口与终端连接。
具体的，以终端与可以连接两个外接设备的一种转接设备建立通信连接进行举例说明，其中两个外接设备可以是耳机和充电器、两个耳机或者耳机和通过数据线与终端进行数据传输的设备等，终端识别通过转接设备接入的两个外接设备的工作模式，以此确定外接设备使用的传输接口的通信通道。
步骤202、终端判断至少两个外接设备的传输接口的通信通道是否相同。
具体的，终端判断通过转接设备与终端连接的至少两个外接设备的传输接口的通信通道是否相同，判断结果包括至少两个外接设备的传输接口的通信通道相同和不相同，其中通信通道不相同包括至少两个外接设备的传输接口的通信通道的信号传输通道至少有一个不相同。例如，当两个外接设备为两个耳机时，两个耳机的传输接口的信号传输通道都为D+、D-，即两个耳机的传输接口的通信通道相同；当两个外接设备分别为耳机和充电器时，耳机的传输接口的信号传输通道为D+、D-，充电器的传输接口的信号传输通道为VBus、D+、D-，即耳机和充电器的传输接口的D+、D-两个信号传输通道相同，但充电器还使用了VBus信号传输通道，因此耳机和充电器的通信通道不相同；当两个外接设备为耳机和通过数据线与终端进行数据传输的设备时，耳机的传输接口的信号传输通道为D+、D-，通过数据线与终端进行数据传输的设备的传输接口的信号传输通道为RX、TX，耳机和通过数据线与终端进行数据传输的设备的传输接口的信号传输通道都不相同，耳机和通过数据线与终端进行数据传输的设备的通信通道不相同。
其中，步骤202终端判断至少两个外接设备的传输接口的通信通道是否相同之后，可以选择执行步骤203或者步骤204，若至少两个外接设备的传输接口的通信通道相同，执行步骤203，若至少两个外接设备的传输接口的通信通道不相同，执行步骤204；
步骤203、若至少两个外接设备的传输接口的通信通道相同，则终端切换终端的工作模式为与转接设备的预设传输接口连接的外接设备的通信模式对应的工作模式。
具体的，转接设备的预设传输接口可以是终端出厂时进行设置的，为转接设备的任意一个传输接口，例如可以是转接设备的第一传输接口。当至少两个通信通道相同的外接设备通过转接设备与终端建立连接时，由于 至少两个通信通道相同，所以终端可以与预设传输接口上接入的外接设备进行通信，保证该外接设备正常工作，无需使用第一切换电路或者第二切换电路进行电路切换。例如，当两个外接设备为两个通信通道相同的耳机时，终端识别两个耳机通信模式的工作模式并进入该工作模式，由于两个耳机的工作模式相同，所以终端可以选择转接设备第一传输接口上接入的耳机，与其进行通信使其正常工作。
步骤204、若至少两个外接设备的传输接口的通信通道不相同，则终端使用第一切换电路或者第二切换电路按照预设规则切换终端的传输接口的工作模式。
具体的，预设规则是为了保证传输接口的通信通道不相同的至少两个外接设备正常工作，规定如何采用第一切换电路或者第二切换电路对终端传输接口的信号传输通道进行切换的规则。
其中，步骤204中按照预设规则切换终端的传输接口的工作模式可以通过以下方式来实现：
a、终端获取至少两个外接设备的预设通信等级。
b、根据预设通信等级，终端使用第一切换电路或者第二切换电路依次切换终端的传输接口的工作模式为与外接设备的通信模式对应的工作模式。
具体的，外接设备的预设通信等级可以是根据外接设备与终端通信的重要程度或者对终端的影响来确定的。例如，由于充电是对手机功能影响最大的因素，所以在预设通信等级中：可以设置充电器的通信等级最高，耳机的通信等级次之，通过数据线与终端进行数据传输的设备的通信等级最低。以终端与可以连接三个外接设备的转接设备连接为例进行说明，当三个外接设备为耳机、标准充电器和通过数据线与终端进行数据传输的设备同时通过转接设备与终端建立连接时，终端识别耳机的工作模式为耳机 模式、标准充电器的工作模式为充电模式、通过数据线与终端进行数据传输的设备的工作模式为安上即可用(OTG，On-The-Go)模式，OTG功能简单地说，手机、平板上的OTG就是方便用户，将手机与U盘、移动硬盘、键鼠、其他数码设备等相连接，并能正常使用其功能。耳机模式对应的信号传输通道为D+、D-，充电模式对应的信号传输通道为VBus、D+、D-，OTG模式对应的信号传输通道为RX、TX；根据预设通信等级，终端首先与标准充电器进行通信，此时终端的工作模式与标准充电器的工作模式(VBus、D+、D-)相同；然后当标准充电器给终端充电稳定后，终端发送控制命令至转接设备，使用第二切换电路切换终端的传输接口的工作模式为耳机的工作模式(如耳机模式)，即保证标准充电器通过VBus信号传输通道给终端进行充电，将D+、D-信号传输切换至耳机的左右声道，与耳机建立通信使耳机正常工作；最后当耳机正常工作后，终端使用第一切换电路切换终端的传输接口的工作模式为通过数据线与终端进行数据传输的设备的工作模式(如OTG模式)，将信号传输通道RX、TX切换给数据线，建立与通过数据线与终端进行数据传输的设备之间的通信，使设备正常工作。
需要说明的是，本实施例中与其它实施例中相同步骤或者概念的解释，可以参照其它实施例中的描述，此处不再赘述。

本公开实施例提供一种信号切换方法，参照图3所示，该方法包括以下步骤：
步骤301、若检测到终端通过转接设备与至少两个外接设备建立连接，则终端识别至少两个外接设备的传输接口的通信通道。
其中，转接设备通过终端的传输接口与终端连接。
步骤302、终端判断至少两个外接设备的传输接口的通信通道是否相同。
其中，步骤302终端判断至少两个外接设备的传输接口的通信通道是否相同之后，可以选择执行步骤303或者步骤304～306，若至少两个外接设备的传输接口的通信通道相同，执行步骤303，若至少两个外接设备的传输接口的通信通道不相同，执行步骤304～306；
步骤303、若至少两个外接设备的传输接口的通信通道相同，则终端切换终端的工作模式为与转接设备的预设传输接口连接的外接设备的通信模式对应的工作模式。
步骤304、若至少两个外接设备的传输接口的通信通道不相同，则终端判断至少两个外接设备的传输接口的通信通道的通信方式是否满足预设条件。
具体的，预设条件为外接设备的传输接口的通信通道的信号传输通道没有短接，例如预设条件可以是D+、D-信号传输通道非短接。
其中，步骤304若至少两个外接设备的传输接口的通信通道不相同，则终端判断至少两个外接设备的传输接口的通信通道的通信方式是否满足预设条件之后，可以选择执行步骤305或者步骤306，若至少两个外接设备的传输接口的通信通道的通信方式满足预设条件，执行步骤305，若至少两个外接设备的传输接口的通信通道的通信方式不满足预设条件，执行步骤306。
步骤305、若至少两个外接设备的传输接口的通信通道的通信方式满足预设条件，则终端使用第一切换电路按照预设规则切换终端的传输接口的工作模式。
步骤306、若至少两个外接设备的传输接口的通信通道的通信方式不满足预设条件，则终端使用第二切换电路按照预设规则切换终端的传输接口的工作模式。
其中，步骤305和步骤306中按照预设规则切换终端的传输接口的工作模式可以通过以下方式来实现：
a、终端获取至少两个外接设备与终端建立连接的接入顺序。
b、根据接入顺序，终端使用第一切换电路或者第二切换电路依次切换终端的传输接口的工作模式为与外接设备的通信模式对应的工作模式。
具体的，当外接设备与终端之间通过转接设备进行连接时有接入的先后顺序，当终端先检测到一个外接设备接入时，识别该外接设备的工作模式，并将终端的传输接口的工作模式切换为该外接设备的工作模式，与该外接设备建立通信连接，实现通信；然后检测转接设备的其他接口上是否有其他设备接入，当有其他设备接入时，识别该设备的工作模式，然后使用第一切换电路切换终端的传输接口的工作模式，实现至少两个设备的正常工作。需注意的是，当终端检测到其他外接设备首先通过转接设备与终端建立通信连接后，检测到充电器通过转接设备与终端建立连接时，终端首先终止其他外接设备与终端之间的通信，与充电器进行通信连接，识别充电器的通信通道，对终端的传输接口的工作模式进行切换，实现对终端的充电，当充电器充电稳定后，根据充电器的信号传输通道D+、D-两个通道之间的关系选择使用终端中的第一切换电路或者转接设备中的第二切换电路对D+、D-信号传输通道进行切换，切换终端的传输接口的工作模式为其他外接设备对应的工作模式，保证终端正常充电的同时保证其他外接设 备也正常工作。以终端通过转接设备外接有三个外接设备(优盘、非标准充电器和耳机)为例进行说明，若这个三个外接设备接入终端的先后顺序依次为：非标准充电器、优盘和耳机；首先终端检测到转接设备上有非标准充电器接入，终端识别非标准充电器的工作模式为充电模式，切换终端的传输接口的工作模式为充电模式，实现对终端的充电；利用非标准充电器进行充电的同时然后继续检测转接设备的其他接口上是否有外接设备接入，当检测到转接设备上有优盘接入且非标准充电器已经稳定给终端充电时，终端识别优盘的工作模式为OTG模式，切换终端的传输接口的工作模式为OTG模式，实现与优盘之间的数据传输通信；利用非标准充电器进行充电以及与优盘充电的同时继续检测转接设备的其他接口上是否有外接设备接入，当终端通过转接设备检测到有耳机接入且与优盘稳定进行数据传输时，识别耳机的工作模式，使用第一切换电路将终端的传输接口的工作模式切换为耳机模式，最终实现非标准充电器、优盘、耳机这三个外接设备通过转接设备与终端正常通信。当终端检测到非标准充电器在上述接入顺序中的优盘后，终端首先终止优盘与终端之间的通信，或者当终端检测到非标准充电器在上述接入顺序中的耳机后，终端首先终止优盘与终端、耳机与终端之间的通信，与非标准充电器建立通信连接，然后使用第一切换电路对终端的工作模式进行切换，实现优盘与终端、耳机与终端之间的通信。
需要说明的是，本实施例中与其它实施例中相同步骤或者概念的解释，可以参照其它实施例中的描述，此处不再赘述。
