目前，电子设备的摄像头与射频系统同时工作时，射频系统的某些频段的工作频率可能会对摄像头产生电磁干扰，导致摄像头预览和拍照时出现花屏或者卡顿现象。现有技术通过对摄像头信号传输走线上增加屏蔽防护，减少射频对其工作产生的影响，但增加了硬件成本。
针对上述问题，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1，图1为电子设备的结构示意图。所述电子设备100包括应用处理器AP 110、调制解调器modem 120、摄像头130和射频天线140，所述射频天线140包括第一天线141和第 二天线142，所述第一天线与所述摄像头的距离小于所述第二天线与所述摄像头的距离，射频天线用于收发信息或通话过程中信号的接收和发送。
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，应用于电子设备，所述电子设备包括应用处理器AP、调制解调器modem、摄像头和射频天线，所述射频天线包括第一天线和第二天线，所述第一天线与所述摄像头的距离小于所述第二天线与所述摄像头的距离，所述AP连接所述调制解调器modem和所述摄像头，所述调制解调器modem连接所述射频天线；如图所示，本电磁干扰控制方法包括：
S201，当电子设备检测到所述电子设备接收到通话业务时，检测所述摄像头的工作状态；
其中，所述摄像头的工作状态包括开启状态和关闭状态；通话业务可以是拨打电话和接听来电，具体的，射频系统通话过程中，通话信号的接收和发送。检测所述电子设备的摄像头是否开启，具体地，可以通过检测用户是否点击对应的按钮或应用，或者通过检测是否点击快速开启拍照功能的按钮，例如检测用户是否点击相机应用，从而判断用户是否开启了摄像头。
S202，所述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；
其中，摄像头工作在最高帧率时，对应的PLL频率会与射频的某些频段的工作频率重合，从而对相机产生干扰。具体的，通过检测PLL频率和射频的工作频率检测是否通话事件的工作天线对相机产生干扰，或者，直接检测当前相机是否出现卡顿或花屏现象判断射频的工作频率检测是否对相机产生干扰。
S203，若是，所述电子设备则在确定出当前启用的天线为所述第一天线时，通过所述应用处理器AP向所述调制解调器modem发送第一预设指令；
其中，当所述当前启用的天线为当前通话进行信号传输的工作天线。当所述进行信号传输的工作天线与摄像头之间发生干扰，且确定当前启用的天线为与摄像头距离较近的第一天线时，通过所述AP向所述调制解调器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，所述电子设备通过所述调制解调器modem接收所述第一预设指令，将启用的天线由所述第一天线切换为所述第二天线。
具体实现中，调制解调器modem根据第一预设指令将当前的工作天线切换到距离摄像头较远的第二天线，以避免第一天线对摄像头造成干扰。
可以看出，本申请实施例中，电子设备检测到所述电子设备接收到通话业务时，首先检测所述摄像头的工作状态；其次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，则在确定出当前启用的主天线为所述第一天线时，通过所述应用处理器AP向所述调制解调器modem发送第一预设指令；最后，通过所述调制解调器modem接收所述第一预设指令，将启用的天线由所述第一天线切换为所述第二天线。可见，电子设备能够通过检测电子设备接收到通话业务时的射频天线的工作频率和摄像头的PLL频率之间的干扰，进而将启用的天线切换到干扰较小的天线，降低了摄像头与通话数据传输时的射频天线之间的电磁干扰，提升了射频通信的效率和有效降低射频系统对手机摄像头产生的干扰，减少相机花屏或者卡顿的情况，提高电子设备成像质量。
在一个可能的示例中，所述方法还包括：若检测到所述摄像头与所述电子设备的射频系统未发生电磁干扰，则在确定出当前启用的天线为所述第一天线时，检测所述第一天线的工作频段；确定仅通过所述工作频段执行信号的传输操作；或，通过所述应用处理器AP向所述调制解调器modem发送第一预设指令；通过所述调制解调器modem接收所述第一预设指令，将启用的天线由所述第一天线切换为所述第二天线。
可选的，所述第一预设指令包括通知所述modem执行天线的切换操作。
其中，手机的射频上天线与后置摄像头的距离较近，在射频工作频段与摄像头工作时对应的PLL频率重合的时候，其发射功率会对相机的成像产生干扰，而在工作频段与摄像头工 作时对应的PLL频率没有重合的则不会对摄像头产生干扰。因此检测没有发生电磁干扰时，确定当前第一天线的工作频率，并将第一天线执行信号的传输的工作频率固定为当前的工作频率。
其中，由于第一天线与摄像头的距离较近，第二天线与摄像头距离较远，执行信号的传输的天线为第一天线时更容易对摄像头产生干扰，因此在检测到当前工作天线为第一天线时切换为第二天线并固定。
可见，本示例中，电子设备能够通过调整第一天线的工作频率或将第一天线切换为第二天线，保证第一天线的工作频率不会对摄像头产生干扰。
在一个可能的示例中，所述方法还包括：若检测到所述摄像头与所述电子设备的射频系统未发生电磁干扰，则确定当前启用的主天线为所述第二天线；通过所述应用处理器AP向所述调制解调器modem发送第二预设指令；通过所述调制解调器modem接收所述第二预设指令，确定仅通过所述第二天线执行信号传输操作。
其中，第二预设指令用于电子设备固定所述第二天线，即将通话业务的工作天线仅设置为第二天线，且其工作天线不能在第一天线和第二天线之间进行切换。
具体实现中，通过检测所述摄像头和所述射频系统之间的干扰情况确定当前启用的天线位置。当前启用的天线位置距离摄像头较远则通过应用处理器发送固定当前天线的指令到调制解调器，使通话事件存在时，仅通过当前位置较远的天线进行数据或信号的传输。
可见，本示例中，电子设备能够基于摄像头和电子设备射频系统的干扰情况确定当前启用的天线的位置，进而根据天线位置发出预设的指令，能够保证将摄像头和射频系统之间的干扰降到最低，保持摄像头拍照的稳定性和清晰度。
在一个可能的示例中，所述方法还包括：若检测到所述摄像头与所述电子设备的射频系统发生电磁干扰，则在确定出当前启用的天线为所述第二天线时，调整所述摄像头的工作帧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；通过所述应用处理器AP向所述调制解调器modem发送第二预设指令；通过所述调制解调器modem接收所述第二预设指令，确定仅通过所述第二天线执行信号传输操作。
其中，电磁干扰产生的主要原因是摄像头工作在最高帧率时，对应的PLL频率会与射频的某些频段的工作频率重合，因此当启用的工作天线为所述第二天线时，通过调整摄像头的工作帧率，以调整对应的PLL频率，减低或避免第二天线与摄像头之间发生电磁干扰。
在一个可能的示例中，在所述执行固定所述第二天线的操作之后，还包括：通过所述应用处理器AP检测所述摄像头是否开启；若否，通过所述应用处理器AP向所述调制解调器modem发送第三预设指令；通过所述调制解调器modem接收所述第三预设指令，恢复针对所述第一天线和所述第二天线的切换功能。
其中，第三预设指令用于恢复所述第一天线和所述第二天线的切换功能。
具体实现中，所述固定所述第二天线后，再检测摄像头的工作状态，若摄像头为开启状态，则持续固定通话事件的工作天线为第二天线；若所述摄像头关闭，则恢复通话事件的工作天线为自由切换状态，提高通话质量。
可见，本示例中，电子设备能够实时或定时检测通话事件持续时间内摄像头的工作状态，进而调整通话事件的工作天线，使通话事件持续时间内电子设备能够自由切换通话事件的工作天线，提高通话信号传输的效率和质量。
在一个可能的示例中，所述检测所述摄像头与所述电子设备的射频系统是否发生干扰，包括：获取所述射频系统的通信频率的至少一个检测值和所述摄像头工作时对应的锁相环PLL频率的至少一个检测值；根据所述通信频率的至少一个检测值和所述锁相环PLL频率的至少一个检测值，检测所述电子设备是否发生电磁干扰。
具体实现中，所述电子设备将锁相环PLL频率和通信频率的检测值进行逐一比对，确定是否会发生电磁干扰。
可见，本示例中，电子设备能够基于频率比对，确定摄像头工作帧率对应的PLL频率和 射频系统启用的工作天线的通信频率是否发生电磁干扰，可以基于实时检测值确定电磁干扰的频率，检测效率高，速度快。
在一个可能的示例中，所述根据所述通信频率的至少一个检测值和所述锁相环PLL频率的至少一个检测值，检测所述电子设备是否发生电磁干扰，包括：根据所述通信频率的至少一个检测值确定通信频率集合，所述通信频率集合包括所述射频系统的至少一个通信频率；根据所述锁相环PLL频率的至少一个检测值确定锁相环PLL频率集合，所述锁相环PLL频率集合包括所述至少一个锁相环PLL频率；根据所述通信频率集合和所述锁相环PLL频率集合的重合率，检测所述电子设备是否发生电磁干扰。
具体实现中，电子设备针对锁相环PLL频率集合中的每个频率，可以逐个与通信频率集合中的频率进行比对，若存在干扰的频率，则确定发生电磁干扰，若不存在，则确定未发生电磁干扰。
可见，本示例中，电子设备能够通过锁相环PLL频率集合和通信频率集合中的频率进行比对，全面、准确的对电磁干扰的发生情况进行检测，提高检测准确度和全面性。
