本申请实施例提供了一种智能平板，用以解决相关技术中智能平板切换后的操作系统无法识别插在切换前的操作系统对应的USB端子处的USB设备的问题，以及由此导致的识别效率较低、操作复杂的问题，该智能平板包括多个系统处理器与多个端子，并且，通过切换单元与集线器，将多个系统处理器与多个端子进行连接，以便于当智能平板处于任意一个操作系统时，对应的系统处理器均能够通过切换单元与集线器与每个端子导通，从而，实现对插入任意端子处的外接设备的识别。
在该思路的引导下，本方案实施例提供了以下可行的实施方案。
实施例一
请参考图1，该智能平板100包括：
至少两个系统处理器110，每个系统处理器对应于一个操作系统；
切换单元120，与每个系统处理器110分别连接；
集线器130，与切换单元连接；
至少两个端子140，每个端子140均与集线器130连接。
在具体实现本方案时，端子140的数目与操作系统的系统处理器110的数目根据需要设定即可。本申请实施例对于端子的数目与系统处理器110的数目是否相等无限定。
在如图1所示的智能平板100中，每个端子140与集线器130之间、集线器130与切换单元120之间可以保持导通状态，那么，当智能平板100所处的操作系统发生切换时，可以通过切换至少两个系统处理器110与切换单元120之间的导通状态实现。
基于前述结构，本申请实施例对于该智能平板中的通道切换方法的工作原理进行简单说明。
如图2所示，该智能平板实现通道切换的方法包括如下步骤：
S202，智能平板当前所处系统的系统处理器向切换单元发送通道切换信号。
S204，切换单元接收到通道切换信号后，导通该系统处理器与切换单元之间的通道。
其中，通道切换信号中可以包括但不限于：智能平板当前所处系统的系统处理器与切换单元之间的通道的标识。基于该通道的标识，切换单元可以确定导通哪一条通道。
本申请实施例所涉及的端子140的类型可以包括但不限于通用串行总线(Universal Serial Bus，USB)，在实际实现本方案时，也可以设定为其他类型的对外通信接口。
为了便于理解，以下以USB端子为例对本方案进行具体说明。
USB端子的类型可以包括但不限于：USB 2.0端子和/或USB 3.0端子。其中，USB 2.0端子可以识别USB 2.0设备，并与USB 2.0设备进行通信。USB 3.0端子可以识别USB 2.0设备和USB 3.0设备，能够与SUB 2.0设备以USB 2.0协议进行通信，并能够与USB 3.0设备以USB 3.0协议进行通信。
目前，一般的操作系统处理器均可以支持USB2.0，而本申请实施例中智能平板100中所能运行的操作系统的系统处理器是否支持USB3.0可以根据需要设定。以及，本申请实施例对于操作系统为内置操作系统还是外置操作 系统也无限定。
在实际的实现场景中，本申请实施例所涉及的操作系统可以包括但不限于：外置个人电脑(Personal Computer，PC)系统、内置安卓(Android)/PC系统或内置安卓/电视(Television，TV)系统。
为了方便进行处理，切换单元120与集线器130是否支持USB 3.0也可以根据需要设置。
基于此，根据操作系统的系统处理器110是否支持USB 3.0，可以存在以下几种情况：
第一种，可以参考图3，该智能平板100中的至少两个系统处理器110中包括：至少一个支持通用串行总线USB 3.0的第一系统处理器111；至少一个支持USB 2.0的第二系统处理器112，并且，集线器130为USB 2.0的集线器，且至少两个端子140中包括至少一个USB 3.0端子141与至少一个USB 2.0端子142。
此时，该集线器130与各端子140之间仅能通过USB 2.0的方式进行通信，为了满足USB 3.0设备插入该USB 3.0端子141时能够有较快的通信速度，那么，在该智能平板100中还可以设置：
第一信号中继器150，连接于USB 3.0端子141与第一系统处理器111之间。
基于上述架构，图3所示的智能平板100中各器件之间的通信方式为：
各第一系统处理器111与切换单元120之间通过USB 2.0通道通信；
各第二系统处理器112与切换单元120之间通过USB 2.0通道通信；
切换单元120与集线器130之间通过USB 2.0通道通信；
各端子140与集线器120之间通过USB 2.0通道通信；
各USB 3.0端子141与各第一信号中继器150之间通过USB 3.0通道通信；
各第一信号中继器150与各第一系统处理器111之间通过USB 3.0通道通信。
第二种，可以参考图4，该智能平板100中的至少两个系统处理器110中包括：至少一个支持通用串行总线USB 3.0的第一系统处理器111；至少一个支持USB 2.0的第二系统处理器112，并且，至少两个端子140均为USB  3.0端子时，集线器130为USB 3.0集线器。
此时，在该智能平板100中还可以设置：
第二信号中继器160，连接于集线器130与各第一系统处理器111之间。
基于上述架构，图4所示的智能平板100中各器件之间的通信方式为：
各第一系统处理器111与切换单元120之间通过USB 2.0通道通信；
各第二系统处理器112与切换单元120之间通过USB 2.0通道通信；
切换单元120与集线器130之间通过USB 2.0通道通信；
各端子140与集线器130之间通过USB 2.0通道或者USB 3.0通道通信；
集线器130与第二信号中继器160之间通过USB 3.0通道通信；
第二信号中继器160与各第一系统处理器111之间通过USB 3.0通道通信。
第三种，可以参考图5，该智能平板100中的至少两个系统处理器110均为第一系统处理器111，并且，至少两个端子140均为USB 3.0端子141时，那么，此时，图5所示的智能平板100中各器件之间的通信方式为：
各第一系统处理器111与切换单元120之间通过USB 2.0通道或者USB 3.0通道通信；
切换单元120与集线器130之间通过USB 2.0通道或者USB 3.0通道通信；
各端子141与集线器130之间通过USB 2.0通道或者USB 3.0通道通信。
第四种，可以参考图6，该智能平板100中的至少两个系统处理器110均为第二系统处理器112，并且，至少两个端子140均为USB 2.0端子142时，那么，此时，图6所示的智能平板100中各器件之间的通信方式为：
各第二系统处理器112与切换单元120之间通过USB 2.0通道通信；
切换单元120与集线器130之间通过USB 2.0通道通信；
各端子142与集线器130之间通过USB 2.0通道通信。
在实际应用过程中，基于切换单元120、集线器130、端子140与系统处理器110所支持的端口类型的区别，其通信方式还可以有其他方式的变形，本申请实施例对此无特别限定。以上四种实现方式为本申请实施例所提供的 智能平板100的几种可行的实现方式，仅用以说明本方案，并不用以限制本申请。
在一个具体的实现场景中，如图7所示，本申请实施例所提供的智能平板中还可以包括：
微处理器170，连接至切换单元120，以及，与至少两个系统处理器110中的主系统处理器113连接。
在一实施例中，主系统处理器113为至少两个系统处理器110中的一个，该主系统处理器113可以仅支持USB 2.0，也可以支持USB 3.0。
其中，当其支持USB 3.0时，考虑到微处理器(Microcontroller Unit，MCU)一般仅支持USB 2.0，因此，微处理器170与切换单元120之间通过USB 2.0通道通信，并且，微处理器170与主系统处理器110-1之间通过USB 2.0通道通信。
那么，基于如图7所示的系统架构，该智能平板100中控制通道切换的方法可以参考图8，包括如下步骤：
S802，智能平板当前所处系统的系统处理器将通道切换信号发送至微处理器。
S804，微处理器将通道切换信号发送至切换单元。
S806，切换单元接收到通道切换信号后，导通该系统处理器与切换单元之间的通道。
在该过程中，微处理器设置为将系统处理器发送的通道切换信号转发至切换单元。
