具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及示例性实施例进行详细描述。
如图1所示，本公开实施例提供一种外置天线检测方法的流程示意图，本公开实施例提供一种外置天线检测方法，包括以下步骤：
步骤S101、检测内置天线接收的第一目标信号的信号强度值、目标无线制式和目标频点。
步骤S102、检测目标端口接收的第二目标信号的信号强度值，所述第二目标信号的无线制式为所述目标无线制式，所述第二目标信号的频点为所述目标频点，所述目标端口为用于检测所述外置天线的端口。
步骤S103、判断所述第一目标信号的信号强度值与所述第二目标信号的信号强度值的差值是否不大于预设第一阈值。
步骤S104、若所述第一目标信号的信号强度值与所述第二目标信号的信号强度值的差值不大于所述预设第一阈值，则确定所述外置天线存在。
在步骤S101中，如图2所示，为检测外置天线是否存在的装置示意图，该电路包括：天线切换控制中央处理器(CPU，Central Processing Unit)201、射频输入端口202、切换开关电路203、射频连接器204、外置天线205、数字信号处理(DSP，Digital Signal Processing)器206和内置天线207。其中，切换开关电路203包括与射频输入端口202连接的输入端口，与天线切换控制CPU201连接的控制端口，与射频连接器204连接的第二输出端口，以及与内置天线207连接的第一输出端口。外置天线205通过射频连接器204与切换开关电路203的第二输出端口连接。
天线切换控制CPU201包括无线信号测量单元2011、判断外置天线是否存在单元2012和切换开关驱动单元2013，如图3所示，为软件模块示意图。天线切换控制CPU201可以和无线终端的基带CPU共用同一个CPU，也可以不共用。
首先，判断外置天线是否存在单元2012通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第一输出端口，即连接到内置天线207，通过内置天线207来接收无线信号。内置天线207接收到无线信号后，无线信号测量单元2011检测内置天线207接收到的无线信号的信号强度(RSSI，Received signal strength indication)，记为RSSI1，并获取内置天线207接收到的无线信号的目标无线制式和目标频点。
在步骤S102中，获取了内置天线207接收到的无线信号的信号强度RSSI1、内置天 线207接收到的无线信号的目标无线制式和内置天线207接收到的无线信号的目标频点后，判断外置天线是否存在单元2012可以通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第二输出端口，即连接到射频连接器204。
判断外置天线是否存在单元2012通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第二输出端口，即连接到射频连接器204后，无线信号测量单元2011在获取到的目标无线制式和目标频点上检测第二目标信号，若在获取到的目标无线制式和目标频点上没有检测到有效的无线信号，说明外置天线205不存在，此时判断外置天线是否存在单元2012通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第一输出端口，即连接到内置天线207，后续无线终端一直使用内置天线207。
若无线信号测量单元2011在获取到的目标无线制式和目标频点上检测到有效的无线信号，无线信号测量单元2011可以获得接收到的有效的无线信号的信号强度，记为RSSI2。
在步骤S103中，无线信号测量单元2011可以判断RSSI1与RSSI2的差值是否不大于预设第一阈值，即判断RSSI1-RSSI2≤Rthres是否成立，也即判断RSSI2≥RSSI1-Rthres是否成立。Rthres可以通过用户界面(UI，User Interface)或者非易失性存储器(NVM，Non-Volatile Memory)来配置，Rthres的取值没有过多的限制，只要保证RSSI1-Rthres的值不小于协议规定的最小可用信号强度值即可。
在步骤S104中，若无线信号测量单元2011判断出RSSI1-RSSI2≤Rthres成立，也即判断出RSSI2≥RSSI1-Rthres成立时，其中，Rthres为配置参数，说明外置天线205是存在的，那么后续无线终端会一直使用外置天线205。
若无线信号测量单元2011判断出RSSI1-RSSI2≤Rthres不成立，也即判断出RSSI2≥RSSI1-Rthres不成立时，其中，Rthres为配置参数，说明外置天线205是不存在的，此时判断外置天线是否存在单元2012通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第一输出端口，即连接到内置天线207，后续无线终端一直使用内置天线207。当外界无线信号很强时，就算外置天线205不存在，无线信号测量单元2011同样可以检测到有效的无线信号，因此此时还要判断RSSI1-RSSI2≤Rthres是否成立，也即判断RSSI2≥RSSI1-Rthres是否成立，若RSSI1-RSSI2≤Rthres不成立，也即RSSI2≥RSSI1-Rthres不成立时，就可以判定外置天线205是不存在的。
需要说明的是，判断无线信号的强弱时，不仅可以使用信号强度RSSI来衡量，也可以根据信号质量或者信噪比来衡量，上述实施方式仅仅是一种举例说明。而且外置天线可以动态拆卸，作为无线终端的一个配件，可以存在也可以不存在，内置天线作为无线终端本身的一部分，永久存在。
本实施例，提出一种外置天线检测方法，通过软件检测的方法检测外置天线是否存在，不需要增加额外的检测电路，降低了检测的成本。
如图4所示，本公开实施例还提供另一种外置天线检测方法的流程示意图，本公开实施例提供另一种外置天线检测方法，包括以下步骤：
步骤S401、检测内置天线接收的第一目标信号的信号强度值、目标无线制式和目标频点。
在步骤S401中，仍然以图2和图3为例，首先，判断外置天线是否存在单元2012通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第一输出端口，即连接到内置天线207，通过内置天线207来接收无线信号。内置天线207接收到无线信号后，无线信号测量单元2011检测内置天线207接收到的无线信号的信号强度，记为RSSI1，并获取内置天线207接收到的无线信号的目标无线制式和目标频点。
步骤S402、检测目标端口接收的第二目标信号的信号强度值，所述第二目标信号的无线制式为所述目标无线制式，所述第二目标信号的频点为所述目标频点，所述目标端口为用于检测所述外置天线的端口。
在步骤S402中，获取了内置天线207接收到的无线信号的信号强度RSSI1、内置天线207接收到的无线信号的目标无线制式和内置天线207接收到的无线信号的目标频点后，判断外置天线是否存在单元2012可以通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第二输出端口，即连接到射频连接器204，无线信号测量单元2011在获取到的目标无线制式和目标频点上检测第二目标信号。
步骤S403、判断所述第二目标信号的信号强度值是否不小于预设第二阈值；若所述第二目标信号的信号强度值不小于所述预设第二阈值，则执行所述判断所述第一目标信号的信号强度值与所述第二目标信号的信号强度值的差值是否不大于预设第一阈值的步骤；若所述第二目标信号的信号强度值小于所述预设第二阈值，则确定所述外置天线不存在。
在步骤S403中，判断外置天线是否存在单元2012通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第二输出端口，即连接到射频连接器204后，无线信号测量单元2011在获取到的目标无线制式和目标频点上检测第二目标信号，若在获取到的目标无线制式和目标频点上没有检测到有效的无线信号，说明外置天线205不存在，此时判断外置天线是否存在单元2012通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第一输出端口，即连接到内置天线207，后续无线终端一直使用内置天线207。
若无线信号测量单元2011在获取到的目标无线制式和目标频点上检测到有效的无线信号，即通过第二输出端口接收到的无线信号的强度不小于预设第二阈值时，无线信号测量单元2011可以获得接收到的有效的无线信号的信号强度，记为RSSI2。
可选的，在所述确定所述外置天线不存在的步骤之后，所述方法还包括：
将当前使用的天线切换为所述内置天线。
确定外置天线205不存在之后，判断外置天线是否存在单元2012通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第一输出端口，即连接到内置天线207，后续无线终端一直使用内置天线207。
步骤S404、判断所述第一目标信号的信号强度值与所述第二目标信号的信号强度值 的差值是否不大于预设第一阈值。
在步骤S404中，无线信号测量单元2011可以在一实施例中判断RSSI1与RSSI2的差值是否不大于预设第一阈值，即判断RSSI1-RSSI2≤Rthres是否成立，也即判断RSSI2≥RSSI1-Rthres是否成立。
步骤S405、若所述第一目标信号的信号强度值与所述第二目标信号的信号强度值的差值不大于所述预设第一阈值，则确定所述外置天线存在。
在步骤S405中，若无线信号测量单元2011判断出RSSI1-RSSI2≤Rthres成立，也即判断出RSSI2≥RSSI1-Rthres成立时，其中，Rthres为配置参数，说明外置天线205是存在的，那么后续无线终端会一直使用外置天线205。
可选的，在所述判断所述第一目标信号的信号强度值与所述第二目标信号的信号强度值的差值是否不大于预设第一阈值的步骤之后，所述方法还包括：
若所述第一目标信号的信号强度值与所述第二目标信号的信号强度值的差值大于所述预设第一阈值，则确定所述外置天线不存在。
若无线信号测量单元2011判断出RSSI1-RSSI2≤Rthres不成立，也即判断出RSSI2≥≥RSSI1-Rthres不成立时，其中，Rthres为配置参数，说明外置天线205是不存在的，此时判断外置天线是否存在单元2012通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第一输出端口，即连接到内置天线207，后续无线终端一直使用内置天线207。当外界无线信号很强时，就算外置天线205不存在，无线信号测量单元2011同样可以检测到有效的无线信号，因此此时还要判断RSSI1-RSSI2≤Rthres是否成立，也即判断RSSI2≥RSSI1-Rthres是否成立，若RSSI1-RSSI2≤Rthres不成立，也即RSSI2≥≥RSSI1-Rthres不成立时，就可以判定外置天线205是不存在的。
可选的，所述信号强度值为信号强度的平均值。
由于无线终端位置的不固定性，以及无线信号强弱的动态变化性，在测量RSSI1和RSSI2时，可以采用周期交替检测的方式。例如，在第一毫秒时，判断外置天线是否存在单元2012通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第一输出端口，即连接到内置天线207，此时无线信号测量单元2011获得信号强度值RSSI11，在第二毫秒时，判断外置天线是否存在单元2012通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第二输出端口，即连接到射频连接器204，此时无线信号测量单元2011获得信号强度值RSSI21，在第三毫秒时，判断外置天线是否存在单元2012通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第一输出端口，即连接到内置天线207，此时无线信号测量单元2011获得信号强度值RSSI12，在第四毫秒时，判断外置天线是否存在单元2012通过切换开关驱动单元2013控制切换开关电路203将切换开关连接到第二输出端口，即连接到射频连接器204，此时无线信号测量单元2011获得信号强度值RSSI22，如此循环下去，到第十毫秒结束时，共获得10个信号强度值，其中有5个信号强度值是切换开关连接到第一输出端口时所获得的信号强度值，分别记 RSSI11、RSSI12、RSSI13、RSSI14和RSSI15，另外5个信号强度值是切换开关连接到第二输出端口时所获得的信号强度值，分别记为RSSI21、RSSI22、RSSI23、RSSI24和RSSI25。
然后对切换开关连接到第一输出端口时所获得的5个信号强度值取平均值，即对RSSI11、RSSI12、RSSI13、RSSI14和RSSI15这5个信号强度值取平均值，并对切换开关连接到第二输出端口时所获得的5个信号强度值取平均值，即对RSSI21、RSSI22、RSSI23、RSSI24和RSSI25这5个信号强度值取平均值，最后再将两个平均值进行比较，当切换开关连接到第一输出端口所获得的5个信号强度值所对应的平均值与切换开关连接到第二输出端口所获得的5个信号强度值所对应的平均值的差值不大于预设第一阈值时，说明外置天线205是存在的，那么后续无线终端会一直使用外置天线205。当切换开关连接到第一输出端口所获得的5个信号强度值所对应的平均值与切换开关连接到第二输出端口所获得的5个信号强度值所对应的平均值的差值大于预设第一阈值时，就可以判定外置天线205是不存在的，那么后续无线终端会一直使用内置天线207。
需要说明的是，判断无线信号的强弱时，不仅可以使用信号强度RSSI来衡量，也可以根据信号质量或者信噪比来衡量，上述实施方式仅仅是一种举例说明。而且外置天线可以动态拆卸，作为无线终端的一个配件，可以存在也可以不存在，内置天线作为无线终端本身的一部分，永久存在。

若检测单元501检测到有效的无线信号，即通过目标端口5021接收到的无线信号的强度不小于预设第二阈值时，检测单元501可以获得接收到的有效的无线信号的信号强度，记为RSSI2。
可选的，所述检测单元501设置为控制所述切换开关电路502的切换开关5022连接到所述内置天线503。
确定外置天线不存在之后，检测单元501控制切换开关电路502将切换开关5022连接到第一输出端口，即连接到内置天线503，后续无线终端一直使用内置天线503。
所述检测单元501设置为判断所述第一目标信号的信号强度值与所述第二目标信号的信号强度值的差值是否不大于预设第一阈值；
检测单元501可以在一实施例中判断RSSI1与RSSI2的差值是否不大于预设第一阈值，即判断RSSI1-RSSI2≤Rthres是否成立，也即判断RSSI2≥RSSI1-Rthres是否成立。
所述检测单元501设置为若所述第一目标信号的信号强度值与所述第二目标信号的信号强度值的差值不大于所述预设第一阈值，则确定所述外置天线存在。
若检测单元501判断出RSSI1-RSSI2≤Rthres成立，也即判断出RSSI2≥RSSI1-Rthres成立时，其中，Rthres为配置参数，说明外置天线是存在的，那么后续无线终端会一直使用外置天线。
可选的，所述检测单元501设置为若所述第一目标信号的信号强度值与所述第二目标信号的信号强度值的差值大于所述预设第一阈值，则确定所述外置天线不存在。
若检测单元501判断出RSSI1-RSSI2≤Rthres不成立，也即判断出RSSI2≥RSSI1- Rthres不成立时，其中，Rthres为配置参数，说明外置天线是不存在的，此时检测单元501控制切换开关电路502将切换开关5022连接到内置天线503，后续无线终端一直使用内置天线503。当外界无线信号很强时，就算外置天线不存在，检测单元501同样可以检测到有效的无线信号，因此此时还要判断RSSI1-RSSI2≤Rthres是否成立，也即判断RSSI2≥RSSI1-Rthres是否成立，若RSSI1-RSSI2≤Rthres不成立，也即RSSI2≥RSSI1-Rthres不成立时，就可以判定外置天线是不存在的。

然后对切换开关连接到第一输出端口时所获得的5个信号强度值取平均值，即对RSSI11、RSSI12、RSSI13、RSSI14和RSSI15这5个信号强度值取平均值，并对切换开关连接到目标端口5021时所获得的5个信号强度值取平均值，即对RSSI21、RSSI22、RSSI23、RSSI24和RSSI25这5个信号强度值取平均值，最后再将两个平均值进行比较，当切换开关连接到第一输出端口所获得的5个信号强度值所对应的平均值与切换开关连接到目标端口5021所获得的5个信号强度值所对应的平均值的差值不大于预设第一阈值时，说明外置天线是存在的，那么后续无线终端会一直使用外置天线。当切换开关连接到第一输出端口所获得的5个信号强度值所对应的平均值与切换开关连接到目标端口5021所获得的5个信号强度值所对应的平均值的差值大于预设第一阈值时，就可以判定外置天线是不存在的，那么后续无线终端会一直使用内置天线503。
