本申请实施例提出一种电磁干扰控制方法，下面结合附图对本申请实施例进行详细介绍。
请参阅图2，图2是本申请实施例提供了一种电磁干扰控制方法的流程示意图，应用于如图1所示的电子设备，如图所示，本控制方法包括：
S201、当检测到所述电子设备的摄像头开启时，检测所述摄像头与所述电子设备的射频系统是否发生电磁干扰。
其中，电磁干扰是指在摄像头与射频系统同时工作时，当射频系统处于某个工作频段时，对摄像头产生干扰。可以通过动态比对检测所述摄像头与所述电子设备的射频系统是否发生电磁干扰，例如，直接获取摄像头的当前工作频率与射频系统的当前工作频率，若两者根据预设规则能够匹配的情况下，则认为射频系统与摄像头之间产生了电磁干扰，也可以通过静态查表检测所述摄像头与所述电子设备的射频系统是否发生电磁干扰，例如，在电子设备中预先建立电磁干扰频率列表，获取射频系统的当前工作频率，如果该工作频率在电磁干扰频率列表中，则认为射频系统与摄像头之间产生了电磁干扰。
S202、若是，则确定当前启用的第一天线，并检测所述第一天线是否为距离所述摄像头最远的天线。
其中，当前启用的第一天线即是当前进行射频传输的天线，在检测所述摄像头与所述电 子设备的射频系统发生电磁干扰时，确定当前启用的第一天线，并检测所述第一天线是否为距离摄像头最远的天线。
S203、若否，则通过所述AP向所述Modem发送第一预设指令。
其中，S203即是在检测所述第一天线不为距离所述摄像头最远的天线时，通过所述AP向所述Modem发送第一预设指令，所述第一预设指令包含通知所述Modem执行天线切换操作。
S204、通过所述Modem接收所述第一预设指令，执行天线切换操作以降低或者避免所述摄像头与所述射频系统之间的电磁干扰。
其中，Modem执行天线切换操作是指Modem将当前射频传输从当前工作天线，即第一天线，切换到不会对摄像头产生电磁干扰或者对摄像头的电磁干扰较小的第二天线。Modem可以根据预设策略执行天线切换操作，其中，所述预设策略可以是根据天线与摄像头的距离执行天线切换操作，所述预设策略还可以是根据天线对摄像头的影响执行天线切换操作，本实施例对预设策略不做限定。
可以看出，本申请实施例中，当电子设备当检测到所述电子设备的摄像头开启时，检测所述摄像头与所述电子设备的射频系统是否发生电磁干扰；若是，则确定当前启用的第一天线，并检测所述第一天线是否为距离所述摄像头最远的天线；若否，则通过所述AP向所述Modem发送第一预设指令；通过所述Modem接收所述第一预设指令，执行天线切换操作以降低或者避免所述摄像头与所述射频系统之间的电磁干扰。可见，本申请实施例的电子设备针对射频系统与摄像头之间的电磁干扰，能够通过执行天线切换操作以降低或者避免，提高电子设备对电磁干扰控制的灵活性、智能性。
在一个可能的示例中，所述获取所述目标应用的用户画像信息，包括：所述执行天线切换操作以降低或者避免所述摄像头与所述射频系统之间的电磁干扰，包括：从所述4根天线中筛选除所述第一天线之外的一根第二天线；切换到所述第二天线，固定所述射频系统与所述第二天线的唯一对应关系。
其中，从所述4根天线中筛选除所述第一天线之外的一根第二天线是指从除当前工作天线的天线中选择一根不会对摄像头产生电磁干扰或者减小对摄像头电磁干扰的天线作为目标天线。固定所述射频系统与所述第二天线的唯一对应关系是指暂时将该条筛选出的天线作为当前射频传输的唯一天线。
可见，本示例中，电子设备能够在切换天线以后，暂时固定射频系统与切换后的天线的唯一对应关系，使得电磁干扰控制更加稳定。
在一个可能的示例中，从所述4根天线中筛选除所述第一天线之外的一根第二天线，包括：从剩余3根天线中筛选出与所述摄像头距离最远的天线作为目标天线。
其中，从剩余3根天线中筛选出与所述摄像头距离最远的天线作为目标天线可以人工对电子设备进行预选设置，直接将与所述摄像头最远的天线作为目标天线预先设置在电子设备中，电子设备直接对其进行定位，也可以是，电子设备直接获取剩余3根天线与摄像头的距离数据，进行比对后，选择数值最大的天线作为目标天线。
可见，本示例中，电子设备能够根据天线与摄像头的距离筛选目标天线来控制电磁干扰，增加了电磁干扰控制的灵活性。
在一个可能的示例中，从所述4根天线中筛选除所述第一天线之外的一根第二天线，包括：确定剩余3根天线中未被握住的天线；当所述未被握住天线的天线为0根时，将所述距离所述摄像头最远的天线作为目标天线；当所述未被握住天线的天线为1根时，将所述天线作为目标天线；当所述未被握住天线的天线为3根时，将距离所述摄像头最远的天线作为目标天线；当所述未被握住天线的天线为2根时，当两根天线与所述摄像头的距离不同时，将距离所述摄像头最远的天线作为目标天线；或者，当两根天线与所述摄像头的距离相同时，选取对所述摄像头干扰最小的天线作为目标天线。
其中，所述未被握住是指天线的发射区域未被用户手掌所遮挡，通过传感器检测剩余3 根天线中未被握住的天线，当剩余3根天线都被握住时，则选择距离摄像头最远的天线作为目标天线，因为，在同等条件下，用于射频传输的天线距离摄像头越远，对摄像头的电磁干扰越小。
可见，本示例中，电子设备能够根据用户的手握来筛选目标天线来控制电磁干扰，使电磁干扰控制更加灵活。
在一个可能的示例中，从所述4根天线中筛选除所述第一天线之外的一根第二天线，包括：从剩余3根天线中筛选出与所述摄像头距离最远且未被握住的天线作为目标天线。
其中，从剩余3根天线中筛选出与所述摄像头距离最远且未被握住的天线作为目标天线可以是先确定剩余天线中距离摄像头最远的天线，再判断该天线是否被握住，直到确定目标天线，也可以先确定剩余3根天线未握住得天线，再从未被握住的天线中选择距离摄像头最远得天线作为目标天线。当剩余3根天线都被握住的情况下，选择距离摄像头最远的天线作为目标天线。
可见，本示例中，电子设备能够根据天线与摄像头的距离筛选目标天线来控制电磁干扰，增加了电磁干扰控制的灵活性。
在一个可能的示例中，若检测到所述第一天线为距离所述摄像头最远的天线，则调整所述摄像头的工作频率以降低或者避免所述摄像头与所述射频系统之间的电磁干扰。

其中，适配可以是指射频系统的当前工作频率与摄像头的当前工作频率完全重合或者接近，适配也可以指射频系统的当前工作频率的分频与摄像头的当前工作频率完全重合或者接近，适配也可以指射频系统的当前工作频率的倍频与摄像头的当前工作频率完全重合或者接近，所述接近是指和在一个预设的差值范围内。所述摄像头的电磁干扰频率列表中可以有所述摄像头的各个工作频率以及各个工作频率的倍频或者分频。
在一个可能的示例中，所述比对所述摄像头的当前工作频率与所述射频系统的当前工作频率，包括:通过所述Modem将所述射频系统的当前工作频率发送到所述AP；通过所述AP将所述射频系统的当前工作频率与所述摄像头的当前工作频率进行比对；或者，通过所述AP将所述摄像头的当前工作频率发送到所述Modem；通过所述Modem将所述摄像头的当前工作频率与所述射频系统的当前工作频率进行比对。
其中，所述比对可以是直接比对，即直接所述摄像头的当前工作频率与所述射频系统的当前工作频率进行比对，所述比对也可以是间接比对，可以是所述摄像头的当前工作频率、当前工作频率的分频或者倍频与所述射频系统的当前工作频率、当前工作频率的分频或者倍频除直接比对之外的任意两者之间的比对。
在一个可能的示例中，所述方法还包括:当检测到所述摄像头关闭时，取消固定所述射频传输与所述第一天线的唯一对应关系，恢复所述电子设备至自由切换天线状态。
