具体实施方式
下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。可以理解的是，此处所描述的具体实施例仅仅用于解释本发明，而非对本发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明相关的部分而非全部结构。
在更加详细地讨论示例性实施例之前应当提到的是，一些示例性实施例被描述成作为流程图描绘的处理或方法。虽然流程图将各步骤描述成顺序的处理，但是其中的许多步骤可以被并行地、并发地或者同时实施。此外，各步骤的顺序可以被重新安排。当其操作完成时所述处理可以被终止，但是还可以具有未包括在附图中的附加步骤。所述处理可以对应于方法、函数、规程、子例程、子程序等等。
实施例一
图1为本发明实施例一提供的一种双***双向控制的方法的流程图。本实施例的方法可以由双***双向控制的装置来执行，该装置可通过硬件和/或软件的方式实现，并一般可独立的配置在交互设备内实现本实施例的方法。
请参考图1，本实施例中的双***双向控制的方法，包括：
S11、分别为主***设备和从***设备生成虚拟网卡并为虚拟网卡生成IP地址。
双***的交互设备，主***设备对从***设备的控制主要通过ADB实现，实现ADB数据传输的物理连接主要是USB(Universal Serial Bus，通用串行总线)，ADB的数据传输本身的传输速度比较慢，并且如果要实现从***设备对主***设备的控制，需要进行较为复杂的数据变化过程，不能直接实现两端的直接传输。
在本方案中，基于两个***设备的网卡，生成虚拟网卡，并为虚拟网卡设定仅互相可知的IP地址，相当于通过虚拟网卡建立专门的数据传输通道，在该数据传输通道内的数据传输相当于通过网络传输，具备理想的带宽，并且点对点的封闭的数据传输通道具备良好的安全性。
S12、根据IP地址建立主***设备和从***设备的数据转发服务的套接字连接。
以网络连接的通道建立主***设备和从***设备的数据转发服务的套接字连接，数据传输的通道专用并且在套接字连接的数据通道中两个***设备间的地位平等，能实现控制指令在两个***设备间的自由传输。
S13、开启对主***设备和从***设备的预设的双向控制服务的端口的监听，对应建立双向控制服务与数据转发服务的套接字连接。
双向控制服务是自定义的服务，用于实现***设备内部不同结构层之间的数据传输。在前序步骤中建立的是两个***设备的底层间的数据连接，在这一步骤中，进一步建立预设的双向控制服务与数据转发服务之间的套接字连接， 最终形成从一个***设备的应用层、架构层到***内核、再到另一个***设备的***内核、架构层即应用层的通道，该通道基于套接字连接实现，能进行携带有控制指令的数据的双向传输，实现双向控制。
步骤S14、当主***设备或从***设备检测到远程控制指令时，通过套接字连接形成的数据通道向对方发送远程控制指令。
当主***设备或从***设备检测到需要发送到另一个***设备的远程控制指令时，通过套接字连接形成的数据通道向对方发送，另一个***设备接收到远程控制指令后根据设定的控制协议对远程控制指令进行响应。
综上所述，本实施例的技术方案，通过分别为主***设备和从***设备生成虚拟网卡并为所述虚拟网卡生成IP地址；根据所述IP地址建立所述主***设备和从***设备的数据转发服务的套接字连接；开启对所述主***设备和从***设备的预设的双向控制服务的端口的监听，对应建立所述双向控制服务与数据转发服务的套接字连接，最终建立双***之间双向控制服务的控制指令传输的数据通道，基于双***的交互设备能够在各种应用场景下选择两个***设备中的一个作为控制主体对另一个进行控制，套接字连接提供更加方便和更大带宽的数据传输方案，同时具备更好的安全性。
实施例二
图2A为本发明实施例二提供的双***双向控制的方法的流程图。在本实施例中，为描述清楚，结合图2B所示的双***的软件***的架构和图2C所示的双***的网络连接的架构进行综合说明。如图2A所示，该方法包括：
步骤S21、为主***设备生成第一虚拟网卡并为第一虚拟网卡生成第一IP 地址，开启主***设备的数据转发服务。
在主***设备的eth0网卡上虚拟一个网卡eth0：1，并且为eth0：1随机生成一个IP地址，为避免IP地址冲突，eth0：1的IP地址可进行特别设定，例如以169.254开头。在本实施例中，两个***设备的操作***基于Android***进行描述，具体架构可以参考图2B。主***设备在设定好IP地址后，即可启动Linux***层的数据转发服务，数据转发服务是两个Android***之间的通信，一旦数据转发服务建立即代表数据转发服务两端之间的通信就可以进行。
步骤S22、在主***设备生成第二IP地址，并通过ADB命令在从***设备生成第二虚拟网卡，将第二IP地址分配给第二虚拟网卡。
在从***设备建立连接的相关操作通过主***设备执行，在主***设备中生成第二IP地址(与第一IP地址相同，也可进行特别设定，例如以169.254开头)，并通过ADB命令在从***设备生成第二虚拟网卡，并将第二IP地址分配给第二虚拟网络，两个***设备的IP地址建立后即可基于网络实现套接字连接。
步骤S23、通过ADB命令将第一IP地址和主***设备的数据转发服务的端口号作为参数启动从***设备的数据转发服务。
步骤S24、由从***设备根据第一IP地址和主***设备的数据转发服务的端口号，建立主***设备和从***设备的数据转发服务的套接字连接。
主***设备的转发服务和从***设备的转发服务在各自知道对方的端口号以及IP地址的情况下，两个数据转发服务可以通过套接字连接。数据转发服务启动并且连接后，各自同时开启端口监听各自来自Android双向控制服务的连接。Linux***层的数据转发服务只负责将收到的数据转发给Android双向控 制服务，或者将收到的数据转发给Android层，不负责数据处理。
步骤S25、当双向控制服务启动时，通过套接字连接实现与对应的数据转发服务的数据连接，并广播双向控制服务已开启。
Android***的双向控制服务启动后，通过套接字连接实现与对应的数据转发服务的数据连接，一旦与Linux***层的数据转发服务相连接，则发送Android***广播通知应用双向控制服务已经可用，可以发送双向控制命令。
步骤S26、当主***设备或从***设备的双向控制服务检测到远程控制指令时，将远程控制指令通过对应的套接字连接依次经由***设备的双向控制服务、数据转发服务、另一***设备的数据转发服务发送到另一***设备的双向控制服务，以使另一***设备对远程控制指令进行响应。
应用层的应用收到双向控制连接上的广播后通过AIDL(Android Interface Definition Language，Android接口定义语言)连接上***中的双向控制服务，应用通过调用双向控制服务暴露出来的接口向另一个***发送控制命令，Android层通过套接字连接发送数据给Linux***层，Linux***层则将数据通过套接字连接传输给另一个***设备的Linux***层，然后另一个Linux***层将数据通过套接字连接转发数据给Android层的双向控制服务。Android层双向控制服务收到数据之后解析得到消息中的命令，然后根据命令做出对应的响应，即可以完成双向控制。
在一个具体的应用场景中，以会议平板为例。现在会议平板大多数尺寸很大，一次性安装后可能需要很久才升级一次硬件。但是CPU、内存却是每年都会推陈出新。因此可以将常用的Android模块作为一个可插拔模块，当有性能更强的模块时候，直接换上性能更强的模块即可，极大的节省了用户的成本。 在上述设计架构下，将负责音视频输入输出和显示的TV方案Android***作为HOST机(主***设备)，可插拔的模块作为Slave机(从***设备)，用户插上可插拔模块使用的时候，用户操作只在Slave机，所以二者***需要互通，例如发送命令去控制整个***的音量大小，调整整个***的亮度，切换输入的通道信号等整机状态，都需要Salve机发送命令个HOST机去操作，在本方案中，基于套接字连接的双向控制服务能方便的处理两个***设备间任意方向的控制操作。
综上所述，本实施例的技术方案，通过分别为主***设备和从***设备生成虚拟网卡并为所述虚拟网卡生成IP地址；根据所述IP地址建立所述主***设备和从***设备的数据转发服务的套接字连接；开启对所述主***设备和从***设备的预设的双向控制服务的端口的监听，对应建立所述双向控制服务与数据转发服务的套接字连接，最终建立双***之间双向控制服务的控制指令传输的数据通道，基于双***的交互设备能够在各种应用场景下选择两个***设备中的一个作为控制主体对另一个进行控制，套接字连接提供更加方便和更大带宽的数据传输方案，同时具备更好的安全性。同时，基于套接字连接的数据传输以及控制指令的响应提高了控制的自由度，增强了交互过程中的用户体验。
