Description

连接器的插入方式的识别方法和装置 技术领域
本申请实施例涉及通信技术，尤其涉及一种连接器的插入方式的识别方法和装置。
背景技术
通常可插拔连接器包括公头和母头，公头是指接口凸出来的一方，母头是指接口凹进去的一方，将一个连接器的公头插入另一个连接器的母头可以实现这两个连接器的连接，从而建立二者间的信号传输链路。目前连接器的接口多采用诸如高清晰多媒体接口(high definition multimedia interface，HDMI)、显示端口(display port，DP)、通用串行总线(universal serial bus，USB)和苹果高速接口(apple lightning)等。
随着电子产品的竞争越来越激烈，如何提高接口性能成为提高信号传输效率的关键技术。
发明内容
本申请实施例提供一种连接器的插入方式的识别方法和装置，无需额外设定专用传输通道来传输特征信息，可以提高接口上的信号传输效率。
第一方面，本申请实施例提供一种连接器的插入方式的识别方法，该方法包括：通过第一传输通道接收第一特征信息，该第一传输通道为连接器的接口包括的多个传输通道中的任意一个，且该第一传输通道为第一类传输通道，上述多个传输通道的排布旋转对称，上述连接器的接口为第一连接器的公头或者第二连接器的母头；当第一特征信息对应于第一类传输通道时，确定第一连接器的公头以第一方向插入第二连接器的母头；当第一特征信息不对应于第一类传输通道时，确定第一连接器的公头以第二方向插入第二连接器的母头；其中，上述第一方向和上述第二方向相反。
本申请实施例的方法适用于第一连接器的公头插入第二连接器的母头的场景下，但并不限定第一连接器和第二连接器的传输方向，即在实施本申请实施例提供的连接器的插入方式的识别方法时，可以是第一连接器(发送端连接器)的公头发送信号，第二连接器(接收端连接器)的母头接收信号；也可以是第二连接器(发送端连接器)的母头发送信号，第一连接器(接收端连接器)的公头接收信号。另外，第一连接器的公头包含的多个传输通道和第二连接器的母头包含的多个传输通道的排布方式相同且均为旋转对称，这样才可以确保第一连接器的公头无论是以第一方向还是以第二方向插入第二连接器的母头时，第一连接器和第二连接器的所有传输通道均可以正常工作。
第一传输通道为接收端连接器的接口包括的多个传输通道中的任意一个。例如，如图2所示，连接器的接口包括8个传输通道，为了确定两个连接器的插入方式，接收端连接器可以基于其中任意一个传输通道实施以下步骤，即接收端连接器可以只检测一个传输通道上接收的特征信息，以确定连接器的插入方式。可选的，也可以基于8个(或少于8个)传输通道实施以下步骤，即连接器可以同时检测多个甚至全部传输通道，可能从其中的一个或多个传输通道上接收到特征信息，然后基于这些特征信息确定连接器的插入方式。无论选择多少个传输通道，各个传输通道的实施方式均相同，因此下文以一个传输通道(第 一传输通道)为例进行说明，其它传输通道均可参照该方法，不再一一赘述。
同样的，本申请实施例中接收端的连接器的接口和发送端的连接器的接口采用旋转对称的结构，因此也可以基于传输通道之间的旋转对称关系，将接口包含的多个传输通道分类为第一类传输通道或第二类传输通道。可选的，也可以将接收端连接器的接口包含的多个传输通道分类为多个类别。本申请实施例中旋转对称的两个传输通道不能归为同一类别，例如Q1_L0和Q3_L0处于旋转对称的位置，则Q1_L0和Q3_L0需要标记为不同的类别，Q2_L1和Q4_L1处于旋转对称的位置，则Q2_L1和Q4_L1需要标记为不同的类别，对传输通道的其他类别划分策略不做具体限定。
接收端连接器的接口包含的多个传输通道和发送端连接器的接口包含的多个传输通道可以基于相同的策略分类。即在发送端连接器的接口中任意一个传输通道的类别与在接收端连接器的接口中对应位置的传输通道的类别一致。
发送端连接器发送特征信息时已经根据第二传输通道的类别对特征信息赋值。那么接收端连接器可以根据接收到的特征信息的值分辨出特征信息对应于哪一类别的传输通道，例如，特征信息对应于第一类传输通道，其表示该特征信息的值与预先设定的用于标识第一类传输通道的类别的标识值一致。本申请可以在对连接器的接口包含的多个传输通道进行分类后，预先设定各个类别的传输通道的标识值，然后将多个传输通道的分类信息和标识值存入连接器的存储器(例如连接器的缓存、内存或其他内部存储器)中，以便于连接器在需要用到上述信息时直接从存储其中读取。接收端连接器的接口包含的多个传输通道和发送端连接器的接口包含的多个传输通道可以基于相同的策略分类。当特征信息来自的传输通道(第二传输通道)的类别与接收该特征信息的传输通道(第一传输通道)的类别一致，表示第一连接器的公头以第一方向(例如正向)插入第二连接器的母头；当特征信息来自的传输通道(第二传输通道)的类别与接收该特征信息的传输通道(第一传输通道)的类别不一致，表示第一连接器的公头以第二方向(例如反向)插入第二连接器的母头。
换个角度来讲，接收端连接器可以基于与发送端连接器相同的类别划分策略，对接口包括的多个传输通道进行分类，而特征信息的取值与传输通道的类别相关联，因此接收端连接器针对第一传输通道传输的特征信息的取值是有预期的，因此若实际接收到的特征信息(来自第二传输通道)的取值与预期的特征信息的取值一致，表示第一连接器的公头以第一方向(例如正向)插入第二连接器的母头；若实际接收到的特征信息(来自第二传输通道)的取值与预期的特征信息的取值不一致，表示第一连接器的公头以第二方向(例如反向)插入第二连接器的母头。
在一种可能的实现方式中，第一特征信息为第一传输通道上接收的信号的同步头；或者，第一特征信息为第一传输通道上接收的握手序列；或者，第一特征信息为第一传输通道上接收的心跳报文。
在一种可能的实现方式中，特征信息可以携带于已有的信号中。
可选的，特征信息可以是第二传输通道上发送的信号的同步头。例如，信号包括同步头(sync head)和数据(data)两部分，以图2为例，预先设定的用于标识第一类传输通道的同步头的取值为0011，用于标识第二类传输通道的同步头的取值为1010，因此发送端连接器可以在Q1_Ly或Q2_Ly上发送的信号的同步头中填入0011，在Q3_Ly和Q4_Ly上发送的信号的同步头中填入1010。
可选的，特征信息也可以是第二传输通道上发送的握手序列。例如，握手序列是发送端连接器和接收端连接器建立连接前发送的序列，以图2为例，预先设定的用于标识第一类传输通道的握手序列的取值为5A5A5A5A，用于标识第二类传输通道的握手序列的取值为3C3C3C3C，因此发送端连接器可以在Q1_Ly或Q2_Ly上发送握手序列5A5A5A5A，在Q3_Ly和Q4_Ly上发送握手序列3C3C3C3C。
可选的，特征信息还可以是第二传输通道上发送的心跳报文。例如，心跳报文是发送端连接器和接收端连接器建立连接后，二者之间定期或不定期发送的心跳检测报文，以图2为例，预先设定的用于标识第一类传输通道的心跳报文的取值为5A5A5A5A，用于标识第二类传输通道的心跳报文的取值为3C3C3C3C，因此发送端连接器可以在Q1_Ly或Q2_Ly上发送心跳报文5A5A5A5A，在Q3_Ly和Q4_Ly上发送心跳报文3C3C3C3C。
需要说明的是，本申请实施例中除了通过上述三种信号传输特征信息外，还可以通过其他已有信号传输特征信息，对此不做具体限定。
在一种可能的实现方式中，特征信息可以携带于本申请实施例新增设的信号中。即在发送端连接器和接收端连接器之间增设新的信号，通过该新的信号传输特征信息。本申请实施例对新增信号的格式和传输机制不做具体限定。
在一种可能的实现方式中，该方法还包括：获取第二特征信息，所述第二特征信息用于标识第二传输通道的类别，该第二传输通道为上述多个传输通道中的任意一个；通过该第二传输通道发送上述第二特征信息。
第二传输通道为发送端连接器的接口包括的多个传输通道中的任意一个。例如，如图2所示，连接器的接口包括8个传输通道，为了确定两个连接器的插入方式，发送端连接器可以基于其中任意一个传输通道实施以下步骤。可选的，也可以基于8个(或少于8个)传输通道实施以下步骤。无论选择多少个传输通道，各个传输通道的实施方式均相同，因此下文以一个传输通道(第二传输通道)为例进行说明，其它传输通道均可参照该方法，不再一一赘述。
特征信息对应于第二传输通道的类别是指特征信息的值与预先设定的用于标识第二传输通道的类别的标识值一致。本申请可以在对连接器的接口包含的多个传输通道进行分类后，预先设定各个类别的传输通道的标识值，然后将多个传输通道的分类信息和标识值存入连接器的存储器(例如连接器的缓存、内存或其他内部存储器)中，以便于连接器在需要用到上述信息时直接从存储其中读取。例如，假设第二传输通道的类别为第一类传输通道，预先设定的用于标识第一类传输通道的取值为0011，当特征信息的值为0011时，该特征信息就被确定是对应于第二传输通道的类别的，当特征信息的值不为0011时，该特征信息就被确定是不对应于第二传输通道的类别的。又例如，假设第二传输通道的类别为第二类传输通道，预先设定的用于标识第二类传输通道的取值为5A5A5A5A，当特征信息的值为5A5A5A5A时，该特征信息就被确定是对应于第二传输通道的类别的，当特征信息的值不为5A5A5A5A时，该特征信息就被确定是不对应于第二传输通道的类别的。
在一种可能的实现方式中，第二特征信息为第二传输通道上发送的信号的同步头；或者，第二特征信息为第二传输通道上发送的握手序列；或者，第二特征信息为第二传输通道上发送的心跳报文。
本申请实施例的连接器的接口包含的多个传输通道是旋转对称的，那么无论公头是正 向插入母头，还是反向插入母头，母头包含的多个传输通道均有对应的公头上的传输通道与其连接，使得公头和母头连接时(即工作时)所有的传输通道都在工作，传输通道的利用率可以达到100％，提高了传输通道的利用率。基于该接口，本申请实施例通过在传输通道上传输具有特定取值含义的特征信息，而特征信息的取值代表了传输通道的类别，若接收到的特征信息的取值与接收该特征信息的传输通道的类别一致，则可以确定第一连接器的公头以第一方向插入第二连接器的母头；若接收到的特征信息的取值与接收该特征信息的传输通道的类别不一致，则可以确定第一连接器的公头以第二方向插入第二连接器的母头。上述传输通道可以是接口包含的多个传输通道中的任意一个，无需额外设定专用传输通道来传输特征信息，可以提高接口上的信号传输效率。
第二方面，本申请实施例提供一种连接器的插入方式的识别方法，该方法包括：获取第二特征信息，所述第二特征信息用于标识第二传输通道的类别，该第二传输通道为连接器的接口包括的多个传输通道中的任意一个，上述多个传输通道的排布为旋转对称，连接器的接口为第一连接器的公头或者第二连接器的母头；通过第二传输通道发送上述第二特征信息。
在一种可能的实现方式中，第二特征信息为第二传输通道上发送的信号的同步头；或者，第二特征信息为第二传输通道上发送的握手序列；或者，第二特征信息为第二传输通道上发送的心跳报文。
在一种可能的实现方式中，通过第二传输通道发送对应于该第二传输通道的类别的第二特征信息，包括：当该第二传输通道为第一类传输通道时，通过该第二传输通道发送对应于第一类传输通道的第二特征信息；或者，当该第二传输通道为第二类传输通道时，通过该第二传输通道发送对应于第二类传输通道的第二特征信息。
在一种可能的实现方式中，该方法还包括：通过第一传输通道接收第一特征信息，该第一传输通道为上述多个传输通道中的任意一个，且该第一传输通道为第一类传输通道；当上述第一特征信息对应于第一类传输通道时，确定第一连接器的公头以第一方向插入第二连接器的母头；当上述第一特征信息不对应于第一类传输通道时，确定第一连接器的公头以第二方向插入第二连接器的母头；其中，上述第一方向和上述第二方向相反。
在一种可能的实现方式中，该第一特征信息为该第一传输通道上接收的信号的同步头；或者，该第一特征信息为该第一传输通道上接收的握手序列；或者，该第一特征信息为该第一传输通道上接收的心跳报文。
在一种可能的实现方式中，第一特征信息对应于第一类传输通道表示该第一特征信息的值与预先设定的用于标识该第一类传输通道的取值一致。
在一种可能的实现方式中，该方法还包括：获取多个传输通道；对该多个传输通道分别进行分类，其中，第一连接器的公头包含的多个传输通道和第二连接器的母头包含的多个传输通道基于相同的策略分类。
第三方面，本申请实施例提供一种连接器的插入方式的识别方法，该方法包括：发送端连接器获取特征信息，该特征信息用于标识第二传输通道的类别；发送端连接器通过第二传输通道发送上述特征信息；接收端连接器通过第一传输通道接收特征信息；当特征信息对应于第一类传输通道时，接收端连接器确定第一连接器的公头以第一方向插入第二连接器的母头；当特征信息对应于非第一类传输通道时，接收端连接器确定第一连接器的公 头以第二方向插入第二连接器的母头。
本申请实施例的方法适用于第一连接器的公头插入第二连接器的母头的场景下，但并不限定第一连接器和第二连接器的传输方向，即在实施本申请实施例提供的连接器的插入方式的识别方法时，可以是第一连接器(发送端连接器)的公头发送信号，第二连接器(接收端连接器)的母头接收信号；也可以是第二连接器(发送端连接器)的母头发送信号，第一连接器(接收端连接器)的公头接收信号。另外，第一连接器的公头包含的多个传输通道和第二连接器的母头包含的多个传输通道的排布方式相同且均为旋转对称，这样才可以确保第一连接器的公头无论是以第一方向还是以第二方向插入第二连接器的母头时，第一连接器和第二连接器的所有传输通道均可以正常工作。
第二传输通道为发送端连接器的接口包括的多个传输通道中的任意一个。例如，如图2所示，连接器的接口包括8个传输通道，为了确定两个连接器的插入方式，发送端连接器可以基于其中任意一个传输通道传输特征信息。可选的，也可以基于8个(或少于8个)传输通道传输特征信息。无论选择多少个传输通道，各个传输通道的实施方式均相同，因此下文以一个传输通道(第二传输通道)为例进行说明，其它传输通道均可参照该方法，不再一一赘述。
发送端连接器的接口采用旋转对称的结构，因此可以基于传输通道之间的旋转对称关系，将接口包含的多个传输通道分别归类为第一类传输通道或第二类传输通道。例如，如图2所示，将Q1_Ly和Q2_Ly归类为第一类传输通道，将Q3_Ly和Q4_Ly归类为第二类传输通道。可选的，也可以将接口包含的多个传输通道分别归类为多个类别。例如，如图2所示，将Q1_Ly归类为第一类传输通道，将Q2_Ly归类为第二类传输通道，将Q3_Ly归类为第三类传输通道，将Q4_Ly归类为第四类传输通道。本申请实施例中旋转对称的两个传输通道不能归为同一类别，例如Q1_L0和Q3_L0处于旋转对称的位置，则Q1_L0和Q3_L0需要标记为不同的类别，Q2_L1和Q4_L1处于旋转对称的位置，则Q2_L1和Q4_L1需要标记为不同的类别，对传输通道的其他类别划分策略不做具体限定。
特征信息对应于第二传输通道的类别是指特征信息的值与预先设定的用于标识第二传输通道的类别的标识值一致。
在一种可能的实现方式中，特征信息可以携带于已有的信号中。
可选的，特征信息可以是第二传输通道上发送的信号的同步头。例如，信号包括同步头(sync head)和数据(data)两部分，例如，预先设定的用于标识第一类传输通道的同步头的取值为0011，用于标识第二类传输通道的同步头的取值为1010。

在一种可能的实现方式中，特征信息可以携带于本申请实施例新增设的信号中。即在发送端连接器和接收端连接器之间增设新的信号，通过该新的信号传输特征信息。本申请实施例对新增信号的格式和传输机制不做具体限定。

发送端连接器发送特征信息时已经根据第二传输通道的类别对特征信息赋值。那么接收端连接器可以根据接收到的特征信息的值分辨出特征信息来自于哪一类别的传输通道。而接收端连接器可以基于与发送端连接器相同的类别划分策略，可以对接口包括的多个传输通道进行归类。当特征信息来自的传输通道(第二传输通道)的类别与接收该特征信息的传输通道(第一传输通道)的类别一致，表示第一连接器的公头以第一方向(例如正向)插入第二连接器的母头；当特征信息来自的传输通道(第二传输通道)的类别与接收该特征信息的传输通道(第一传输通道)的类别不一致，表示第一连接器的公头以第二方向(例如反向)插入第二连接器的母头。

图1a和图1b为本申请实施例旋转对称结构的一个示例性的结构图，如图1a所示，连接器的接口(例如连接器的公头或者连接器的母头)包括N×M个传输通道(lane)，一个传输通道(Qx_Ly)可以由一条线(line)(K＝1)构成，或者，一个传输通道(Qx_Ly)也可以由一对差分线(K＝2)构成，或者，一个传输通道(Qx_Ly)还可以由三根线(K＝3)构成，或者，一个传输通道(Qx_Ly)还可以由更多根线(K＝n)构成，本申请实施例对K的取值不做具体限定。一个传输通道对应的K根线共同传输一个有效信号。一根线对应接口上的一个引脚。本申请实施例中N×M个传输通道的排布旋转对称，即将连接器的接口翻转180°后得到如图1b所示的结构，与图1a相比可见，Q4_Ly和Q2_Ly互换位置，Q3_Ly和Q1_Ly互换位置。因此Q4_Ly和Q2_Ly是旋转对称的关系，Q3_Ly和Q1_Ly是旋转对称的关系，其中，y＝0,1,2或3。
例如，图2为本申请实施例连接器的接口的一个示例性的结构图，如图2所示，该连接器的接口包括8个传输通道(Q1_L0、Q1_L1、Q2_L0、Q2_L1、Q3_L0、Q3_L1、Q4_L0和Q4_L1)，其中，N＝4，M＝2，K＝1。根据该8个传输通道的排列位置，可以知道Q4_Ly和Q2_Ly是旋转对称的关系，Q3_Ly和Q1_Ly是旋转对称的关系，y＝0或1。
图3a为本身申请正插方式的一个示例性的示意图，如图3a所示，第一连接器的公头正向插入第二连接器的母头，第一连接器的公头和第二连接器的母头均采用图2所示的结构，包括8个传输通道(Q1_L0、Q1_L1、Q2_L0、Q2_L1、Q3_L0、Q3_L1、Q4_L0和Q4_L1)，其中，Q4_Ly和Q2_Ly是旋转对称的关系，Q3_Ly和Q1_Ly是旋转对称的关系，y＝0或1。
第一连接器的公头正向插入第二连接器的母头后，第一连接器的公头的Q1_L0和第二连接器的母头的Q1_L0建立连接，第一连接器的公头的Q1_L1和第二连接器的母头的Q1_L1建立连接；第一连接器的公头的Q2_L0和第二连接器的母头的Q2_L0建立连接，第一连接器的公头的Q2_L1和第二连接器的母头的Q2_L1建立连接；第一连接器的公头的Q3_L0和第二连接器的母头的Q3_L0建立连接，第一连接器的公头的Q3_L1和第二连接器的母头的Q3_L1建立连接；第一连接器的公头的Q4_L0和第二连接器的母头的Q4_L0 建立连接，第一连接器的公头的Q4_L1和第二连接器的母头的Q4_L1建立连接。
图3b为本申请实施例反插方式的一个示例性的示意图，如图3b所示，第一连接器的公头反向插入第二连接器的母头，第一连接器的公头和第二连接器的母头均采用图2所示的结构，包括8个传输通道(Q1_L0、Q1_L1、Q2_L0、Q2_L1、Q3_L0、Q3_L1、Q4_L0和Q4_L1)，其中，Q4_Ly和Q2_Ly是旋转对称的关系，Q3_Ly和Q1_Ly是旋转对称的关系，y＝0或1。
第一连接器的公头反向插入第二连接器的母头后，第一连接器的公头的Q1_L0和第二连接器的母头的Q3_L0建立连接，第一连接器的公头的Q1_L1和第二连接器的母头的Q3_L1建立连接；第一连接器的公头的Q2_L0和第二连接器的母头的Q4_L0建立连接，第一连接器的公头的Q2_L1和第二连接器的母头的Q4_L1建立连接；第一连接器的公头的Q3_L0和第二连接器的母头的Q1_L0建立连接，第一连接器的公头的Q3_L1和第二连接器的母头的Q1_L1建立连接；第一连接器的公头的Q4_L0和第二连接器的母头的Q2_L0建立连接，第一连接器的公头的Q4_L1和第二连接器的母头的Q2_L1建立连接。
图3c为本申请实施例Type-C公头的一个示例性的示意图，如图3c所示，在连接器的公头的两侧设置相同的信号线。图3d为本申请实施例Type-C母头的一个示例性的示意图，如图3d所示，在连接器的母头的两侧中仅一侧设置信号线，另一侧没有设置信号线。可见Type-C接口，无论公头是正向还是反向插入母头，公头的两侧中总有一侧的信号线与母头设置有信号线的一侧相连，这样即可正常使用。但是，由于母头只有一侧设置有信号线，即使公头的两侧均设置有相同的信号线，实际上公头和母头连接时(即工作时)只有一组信号线在工作，使得Type-C接口的信号线的利用率只有50％，影响了信号传输效率。
由此可见，相较于Type-C接口，本申请实施例的连接器的接口包含的多个传输通道是旋转对称的，那么无论公头是正向插入母头，还是反向插入母头，母头包含的多个传输通道均有对应的公头上的传输通道与其连接，使得公头和母头连接时(即工作时)所有的传输通道都在工作，传输通道的利用率可以达到100％，提高了信号传输效率。
图4为本申请实施例连接器的一个示例性的结构图，如图4所示，该连接器包括至少一个处理器411、至少一个存储器412和至少一个接口413。处理器411、存储器412和接口413连接，例如通过总线连接。在本申请实施例中，所述连接可包括各类接口、传输线或总线等，本申请实施例对此不做具体限定。
处理器411主要用于对通信协议以及通信数据进行处理，以及对整个连接器进行控制，执行软件程序，处理软件程序的数据。处理器411可以包括一个或多个处理单元，例如：处理器411可以包括应用处理器(application processor，AP)，调制解调处理器，图形处理器(graphics processing unit，GPU)，图像信号处理器(image signal processor，ISP)，控制器，视频编解码器，数字信号处理器(digital signal processor，DSP)，基带处理器，和/或神经网络处理器(neural-network processing unit，NPU)等。其中，不同的处理单元可以是独立的器件，也可以集成在一个或多个处理器中。
存储器412主要用于存储软件程序和数据。存储器412可以是独立存在(独立的存储元件)，与处理器411连接。可选的，存储器412可以和处理器411集成在一起，例如集成在一个芯片之内(片内存储元件)。其中，存储器412可以用于存储计算机可执行程 序代码，所述可执行程序代码包括指令。存储器412可以包括存储程序区和存储数据区。其中，存储程序区可存储操作系统，至少一个功能所需的应用程序等。此外，存储器412可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件，闪存器件，通用闪存存储器(universal flash storage，UFS)等。处理器411通过运行存储在存储器412的指令，和/或存储在设置于处理器中的存储器的指令，执行本申请实施例的技术方案和数据处理。
接口413主要用于接收和/或发送信号。本申请实施例中的接口413可以采用图1a～2任一所示接口的结构。接口413可以包括集成电路(inter-integrated circuit，I2C)接口，集成电路内置音频(inter-integrated circuit sound，I2S)接口，脉冲编码调制(pulse code modulation，PCM)接口，通用异步收发传输器(universal asynchronous receiver/transmitter，UART)接口，移动产业处理器接口(mobile industry processor interface，MIPI)，通用输入输出(general-purpose input/output，GPIO)接口，用户标识模块(subscriber identity module，SIM)接口，通用串行总线(universal serial bus，USB)接口，高清多媒体接口(high definition multimedia interface，HDMI)、移动产业处理器接口(mobile industry processor interface，MIPI)接口和/或图1a～图3b任一实施例所示的接口等。
图4仅示出了一个存储器、一个处理器和一个接口。在实际的连接器中，可以存在多个处理器、多个存储器和多个接口，本申请实施例对此不做具体限定。
图5为本申请实施例连接器的插入方式的识别方法的一个示例性的流程图，如图5所示，该过程500可以由连接器(包括发送端连接器和接收端连接器)，例如图4所示连接器执行。过程500描述为一系列的步骤或操作，应当理解的是，过程500可以以各种顺序执行和/或同时发生，不限于图5所示的执行顺序。
本申请实施例的方法适用于第一连接器的公头插入第二连接器的母头的场景下，但并不限定第一连接器和第二连接器的传输方向，即在实施本申请实施例提供的连接器的插入方式的识别方法时，可以是第一连接器(发送端连接器)的公头发送信号，第二连接器(接收端连接器)的母头接收信号；也可以是第二连接器(发送端连接器)的母头发送信号，第一连接器(接收端连接器)的公头接收信号。另外，第一连接器的公头包含的多个传输通道和第二连接器的母头包含的多个传输通道的排布方式相同且均为旋转对称，这样才可以确保第一连接器的公头无论是以第一方向还是以第二方向插入第二连接器的母头时，第一连接器和第二连接器的所有传输通道均可以正常工作。
步骤501、发送端连接器获取第二特征信息，该第二特征信息用于标识第二传输通道的类别。
第二传输通道为发送端连接器的接口包括的多个传输通道中的任意一个。例如，如图2所示，连接器的接口包括8个传输通道，为了确定两个连接器的插入方式，发送端连接器可以基于其中任意一个传输通道实施以下步骤。可选的，也可以基于8个(或少于8个)传输通道实施以下步骤。无论选择多少个传输通道，各个传输通道的实施方式均相同，因此下文以一个传输通道(第二传输通道)为例进行说明，其它传输通道均可参照该方法，不再一一赘述。
如上所述，发送端连接器的接口采用旋转对称的结构，因此可以基于传输通道之间的 旋转对称关系，将接口包含的多个传输通道分别归类为第一类传输通道或第二类传输通道。例如，如图2所示，将Q1_Ly和Q2_Ly归类为第一类传输通道，将Q3_Ly和Q4_Ly归类为第二类传输通道。可选的，也可以将接口包含的多个传输通道分别归类为多个类别。例如，如图2所示，将Q1_Ly归类为第一类传输通道，将Q2_Ly归类为第二类传输通道，将Q3_Ly归类为第三类传输通道，将Q4_Ly归类为第四类传输通道。本申请实施例中旋转对称的两个传输通道不能归为同一类别，例如Q1_L0和Q3_L0处于旋转对称的位置，则Q1_L0和Q3_L0需要标记为不同的类别，Q2_L1和Q4_L1处于旋转对称的位置，则Q2_L1和Q4_L1需要标记为不同的类别，对传输通道的其他类别划分策略不做具体限定。
特征信息对应于第二传输通道的类别是指特征信息的值与预先设定的用于标识第二传输通道的类别的标识值一致。例如，假设第二传输通道的类别为第一类传输通道，预先设定的用于标识第一类传输通道的取值为0011，当特征信息的值为0011时，该特征信息就被确定是对应于第二传输通道的类别的，当特征信息的值不为0011时，该特征信息就被确定是不对应于第二传输通道的类别的。又例如，假设第二传输通道的类别为第二类传输通道，预先设定的用于标识第二类传输通道的取值为5A5A5A5A，当特征信息的值为5A5A5A5A时，该特征信息就被确定是对应于第二传输通道的类别的，当特征信息的值不为5A5A5A5A时，该特征信息就被确定是不对应于第二传输通道的类别的。
在一种可能的实现方式中，特征信息可以携带于已有的信号中。
可选的，特征信息可以是第二传输通道上发送的信号的同步头。例如，信号包括同步头(sync head)和数据(data)两部分，以图2为例，预先设定的用于标识第一类传输通道的同步头的取值为0011，用于标识第二类传输通道的同步头的取值为1010，因此发送端连接器可以在Q1_Ly或Q2_Ly上发送的信号的同步头中填入0011，在Q3_Ly和Q4_Ly上发送的信号的同步头中填入1010。
可选的，特征信息也可以是第二传输通道上发送的握手序列。例如，握手序列是发送端连接器和接收端连接器建立连接前发送的序列，以图2为例，预先设定的用于标识第一类传输通道的握手序列的取值为5A5A5A5A，用于标识第二类传输通道的握手序列的取值为3C3C3C3C，因此发送端连接器可以在Q1_Ly或Q2_Ly上发送握手序列5A5A5A5A，在Q3_Ly和Q4_Ly上发送握手序列3C3C3C3C。
可选的，特征信息还可以是第二传输通道上发送的心跳报文。例如，心跳报文是发送端连接器和接收端连接器建立连接后，二者之间定期或不定期发送的心跳检测报文，以图2为例，预先设定的用于标识第一类传输通道的心跳报文的取值为5A5A5A5A，用于标识第二类传输通道的心跳报文的取值为3C3C3C3C，因此发送端连接器可以在Q1_Ly或Q2_Ly上发送心跳报文5A5A5A5A，在Q3_Ly和Q4_Ly上发送心跳报文3C3C3C3C。
需要说明的是，本申请实施例中除了通过上述三种信号传输特征信息外，还可以通过其他已有信号传输特征信息，对此不做具体限定。
在一种可能的实现方式中，特征信息可以携带于本申请实施例新增设的信号中。即在发送端连接器和接收端连接器之间增设新的信号，通过该新的信号传输特征信息。本申请实施例对新增信号的格式和传输机制不做具体限定。
步骤502、发送端连接器通过第二传输通道发送特征信息。
发送端连接器可以在第二传输通道上发送该特征信息，特征信息的实现方式可以参照 上述几种情况，特征信息的取值可以与第二传输通道的类别对应，此处不再赘述。
步骤503、接收端连接器通过第一传输通道接收特征信息。
第一传输通道为接收端连接器的接口包括的多个传输通道中的任意一个。例如，如图2所示，连接器的接口包括8个传输通道，为了确定两个连接器的插入方式，接收端连接器可以基于其中任意一个传输通道实施以下步骤，即接收端连接器可以只检测一个传输通道上接收的特征信息，以确定连接器的插入方式。可选的，也可以基于8个(或少于8个)传输通道实施以下步骤，即连接器可以同时检测多个甚至全部传输通道，可能从其中的一个或多个传输通道上接收到特征信息，然后基于这些特征信息确定连接器的插入方式。无论选择多少个传输通道，各个传输通道的实施方式均相同，因此下文以一个传输通道(第一传输通道)为例进行说明，其它传输通道均可参照该方法，不再一一赘述。需要说明的是，第一传输通道和步骤501中的第二传输通道可以是指同一个传输通道，也可以是指不同的传输通道，本申请实施例对此不做具体限定。
同样的，本申请实施例中接收端的连接器的接口和发送端的连接器的接口采用旋转对称的结构，因此也可以基于传输通道之间的旋转对称关系，将接口包含的多个传输通道分别归类为第一类传输通道或第二类传输通道。可选的，也可以将接收端连接器的接口包含的多个传输通道分别归类为多个类别。本申请实施例中旋转对称的两个传输通道不能归为同一类别，例如Q1_L0和Q3_L0处于旋转对称的位置，则Q1_L0和Q3_L0需要标记为不同的类别，Q2_L1和Q4_L1处于旋转对称的位置，则Q2_L1和Q4_L1需要标记为不同的类别，对传输通道的其他类别划分策略不做具体限定。
接收端连接器的接口包含的多个传输通道和发送端连接器的接口包含的多个传输通道可以基于相同的策略分类。即在发送端连接器的接口中任意一个传输通道的类别与在接收端连接器的接口中该传输通道的类别一致。
步骤504a、当特征信息对应于第一类传输通道时，接收端连接器确定第一连接器的公头以第一方向插入第二连接器的母头。
步骤504b、当特征信息对应于非第一类传输通道时，接收端连接器确定第一连接器的公头以第二方向插入第二连接器的母头。
步骤504a和504b是二选一的可选步骤，即根据特征信息对应的传输通道的类别确定是执行步骤504a还是步骤504b。
发送端连接器发送特征信息时已经根据第二传输通道的类别对特征信息赋值。那么接收端连接器可以根据接收到的特征信息的值分辨出特征信息来自于哪一类别的传输通道。接收端连接器的接口包含的多个传输通道和发送端连接器的接口包含的多个传输通道可以基于相同的策略分类。当特征信息来自的传输通道(第二传输通道)的类别与接收该特征信息的传输通道(第一传输通道)的类别一致，表示第一连接器的公头以第一方向(例如正向)插入第二连接器的母头；当特征信息来自的传输通道(第二传输通道)的类别与接收该特征信息的传输通道(第一传输通道)的类别不一致，表示第一连接器的公头以第二方向(例如反向)插入第二连接器的母头。
例如，以图2为例，接收端连接器从Q1_Ly上接收到特征信息为取值为0011的同步头时，可以确定该特征信息来自第一类传输通道。而Q1_Ly属于第一类传输通道，因此可以确定第一连接器的公头以第一方向(例如正向)插入第二连接器的母头。或者，接收 端连接器从Q3_Ly上接收到特征信息为取值为0011的同步头时，可以确定该特征信息来自第一类传输通道。而Q3_Ly属于第二类传输通道，因此可以确定第一连接器的公头以第二方向(例如反向)插入第二连接器的母头。
换个角度来讲，接收端连接器可以基于与发送端连接器相同的类别划分策略，对接口包括的多个传输通道进行分类，而特征信息的取值与传输通道的类别相关联，因此接收端连接器针对第一传输通道传输的特征信息的取值是有预期的，因此若实际接收到的特征信息(来自第二传输通道)的取值与预期的特征信息的取值一致，表示第一连接器的公头以第一方向(例如正向)插入第二连接器的母头；若实际接收到的特征信息(来自第二传输通道)的取值与预期的特征信息的取值不一致，表示第一连接器的公头以第二方向(例如反向)插入第二连接器的母头。
例如，以图2为例，接收端连接器从Q1_Ly(预期的特征信息的取值为0011)上接收到特征信息为取值为0011的同步头时，可以确定第一连接器的公头以第一方向(例如正向)插入第二连接器的母头。或者，接收端连接器从Q3_Ly(预期的特征信息的取值为1010)上接收到特征信息为取值为0011的同步头时，可以确定第一连接器的公头以第二方向(例如反向)插入第二连接器的母头。
本申请实施例的连接器的接口包含的多个传输通道是旋转对称的，那么无论公头是正向插入母头，还是反向插入母头，母头包含的多个传输通道均有对应的公头上的传输通道与其连接，使得公头和母头连接时(即工作时)所有的传输通道都在工作，传输通道的利用率可以达到100％，提高了传输通道的利用率。基于该接口，本申请实施例通过在传输通道上传输具有特定取值含义的特征信息，而特征信息的取值代表了传输通道的类别，若接收到的特征信息的取值与接收该特征信息的传输通道的类别一致，则可以确定第一连接器的公头以第一方向插入第二连接器的母头；若接收到的特征信息的取值与接收该特征信息的传输通道的类别不一致，则可以确定第一连接器的公头以第二方向插入第二连接器的母头。上述传输通道可以是接口包含的多个传输通道中的任意一个，无需额外设定专用传输通道来传输特征信息，可以提高接口上的信号传输效率。
下面采用几个具体的实施例，对图5所示方法实施例的技术方案进行详细说明。
实施例一、特征信息为信号的同步头
以图2为例，Q1_Ly和Q2_Ly归类为第一类传输通道，Q3_Ly和Q4_Ly归类为第二类传输通道。以Q1_Ly和Q3_Ly为例，图6为本申请实施例信号的一个示例性的示意图，如图6所示，发送端连接器在Q1_Ly上发送sync head1作为同步头，每个同步头后跟一段data数据，在Q3_Lx上发送sync head2作为同步头，每个同步头后跟一段data数据。接收端连接器接收Q1_Ly和Q3_Ly上的特征信息，如果Q1_Ly上接收的信号的同步头为sync head1，Q3_Ly上接收的信号的同步头为sync head2，确定第一连接器的公头正向插入第二连接器的母头；如果Q1_Ly上接收的信号的同步头为sync head2，Q3_Ly上接收的信号的同步头为sync head1，确定第一连接器的公头反向插入第二连接器的母头。
实施例二、特征信息为握手序列
图7为本申请实施例接口的一个示例性的结构图，如图7所示，接口中的传输通道有两个方向，其中，Tx*y(y＝0～N)表示发送信道，Rx*y(y＝0～N)表示接收信道。TxAy和RxAy归类为第一类传输通道，TxBy和RxBy归类为第二类传输通道。在建立连接之 前，发送端连接器在TxAy上发送握手序列handshake_signal_A(0x0000FFFF_5A5A5A5A_FFFF0000)，在TxBy上发送握手序列handshake_signal_B(0x0000FFFF_3C3C3C3C_FFFF0000)。接收端连接器从RxAy和RxBy上接收特征信息，如果RxAy上接收的握手序列为handshake_signal_A，RxBy上接收的握手序列为handshake_signal_B，确定第一连接器的公头正向插入第二连接器的母头；如果RxAy上接收的握手序列为handshake_signal_B，RxBy上接收的握手序列为handshake_signal_A，确定第一连接器的公头反向插入第二连接器的母头。
实施例三、特征信息为心跳报文
以图7为例，建立连接之后，发送端连接器在TxAy上发送心跳报文heartbeat_signal_A(0x0000FFFF_5A5A5A5A_FFFF0000)，在TxBy上发送心跳报文heartbeat_signal_B(0x0000FFFF_3C3C3C3C_FFFF0000)。接收端连接器从RxAy和RxBy上接收特征信息，如果RxAy上接收的心跳报文为heartbeat_signal_A，RxBy上接收的心跳报文为heartbeat_signal_B，确定第一连接器的公头正向插入第二连接器的母头；如果RxAy上接收的心跳报文为heartbeat_signal_B，RxBy上接收的心跳报文为heartbeat_signal_A，确定第一连接器的公头反向插入第二连接器的母头。
图8为本申请实施例连接装置的一个示例性的结构示意图，如图8所示，本实施例的连接装置可以应用于上述实施例中的第一连接器或第二连接器，例如图4所示的连接器。该连接装置包括：接收模块801、确定模块802、获取模块803和发送模块804。其中，
