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：
步骤201，当电子设备检测到所述电子设备的摄像头处于开启状态时，检测所述摄像头与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的锁相环(Phase-locked loops，PLL)频率(即摄像头的工作频率)与所述电子设备的射频系统的工作频率来确定两者是否发生电磁干扰，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。
步骤202，若是，则上述电子设备检测所述电子设备的屏幕状态，并根据所述屏幕状态确定所述四根天线的动态切换策略，所述屏幕状态包括横屏状态和竖屏状态，所述动态切换策略包括所述四根天线的检测优先级序列以及切换条件。
其中，所述电子设备外围的边框具有人手握持检测装置，当电子设备处于横屏或竖屏状态且电子设备处于亮屏工作状态时，所述人手握持检测装置将检测当前用户的握持区域，检测出握持区域后电子设备首先确定当前的系统时间并结合当前的屏幕状态生成握持记录。当所述人手握持检测装置检测到用户的握持区域发生变化时，首先确定上一握持区域的握持时间并保存至上一握持区域生成的握持记录中，将重新检测用户的握持区域并执行上述循环操作。因此将会生成大量的握持记录，根据同一屏幕状态下每个握持记录中的握持区域和握持时间确定上述四根天线被遮挡的次数并生成检测优先级序列。
步骤203，所述电子设备按照所述动态切换策略检测除当前启用的天线之外的至少一根天线的通信质量，并在所述通信质量满足所述切换条件时执行天线切换操作以避免或者降低所述电磁干扰。
其中，电子设备根据动态切换策略中的检测优先级对四根天线逐一检测，当根据检测优先级序列轮到检测所述当前启用的天线时，则跳过当前启用的天线，检测所述检测优先级序列中当前启用的天线之后的一根天线。
可以看出，本申请实施例中，当电子设备检测到所述电子设备的摄像头处于开启状态时，检测所述摄像头与射频系统是否发生电磁干扰；若是，则检测所述电子设备的屏幕状态，并根据所述屏幕状态确定所述四根天线的动态切换策略，所述屏幕状态包括横屏状态和竖屏状态，所述动态切换策略包括所述四根天线的检测优先级序列以及切换条件；按照所述动态切换策略检测除当前启用的天线之外的至少一根天线的通信质量，并在所述通信质量满足所述切换条件时执行天线切换操作以避免或者降低所述电磁干扰。可见，本申请实施例的电子设备在检测到射频系统与摄像头之间的电磁干扰时，能够根据当前的屏幕状态执行天线切换操作以降低或者避免电磁干扰。
在一个可能的示例中，所述电子设备根据所述屏幕状态确定所述四根天线的动态切换策略，包括：以所述屏幕状态为查询标识，查询映射关系，获取所述屏幕状态对应的动态切换策略，所述映射关系包括屏幕状态与动态切换策略之间的对应关系。
其中，屏幕状态包括横屏状态和竖屏状态,映射关系包括横屏状态与横屏状态对应的动态切换策略之间的映射关系和竖屏状态与竖屏状态对应的动态切换策略之间的映射关系。其中，横屏状态和竖屏状态对应的动态切换策略不同的原因为：当用户在横屏握持电子设备或竖屏握持电子设备时，握持的区域不同，对不同位置的天线的影响大小不同。
举例来说，当电子设备检测出屏幕状态为横屏状态时，电子设备查询映射关系获取横 屏状态对应的横屏状态下的横屏天线切换策略；当电子设备检测出屏幕状态为竖屏状态时，电子设备查询映射关系获取竖屏状态对应的竖屏状态下的竖屏天线切换策略。
可见，本示例中，电子设备可根据当前的屏幕状态查询映射关系确定动态切换策略，提高了天线的切换效率。
在一个可能的示例中，所述电子设备查询映射关系之前，所述方法还包括：获取所述电子设备的多个握持记录，每个握持记录包括屏幕状态和握持区域；筛选出相同屏幕状态的第一数量的第一握持记录；根据所述第一数量的第一握持记录中每个第一握持记录的握持区域确定所述每个握持记录对应的被遮挡的天线；根据所述第一数量的第一握持记录和所述每个第一握持记录对应的被遮挡的天线，确定所述四根天线中每根天线在所述相同屏幕状态下被遮挡的概率；根据所述每根天线被遮挡的概率确定所述四根天线在所述相同屏幕状态下的检测优先级序列；根据所述检测优先级序列和所述切换条件生成动态切换策略；创建所述相同屏幕状态与所述动态切换策略之间的对应关系以形成所述映射关系。
其中，每次握持记录中还包括每次握持区域的握持时间，电子设备可根据相同屏幕状态下每次握持区域和握持时间确定对应区域在相同屏幕状态下握持的总时间，将对应区域握持的总时间除以电子设备在相同屏幕状态下总的握持时间可得到对应区域在相同屏幕状态下被握持的概率，进而得到握持对应区域时遮挡的天线的被遮挡的概率。可选的，也可不根据时间确定，只根据每次握持的区域和握持次数确定对应区域被握持的概率，进而确定握持对应区域遮挡的天线的被遮挡概率。
可见，本示例中，电子设备可根据存储的握持记录确定每根天线被遮挡的概率，进而生成检测优先级，提高了电子设备的智能性，同时电子设备根据检测优先级进行天线的检测和切换操作时，提高了天线切换的效率。
在一个可能的示例中，所述电子设备查询映射关系之前，所述方法还包括：电子设备根据用户的设置操作确定相同屏幕状态下所述四根天线的检测优先级序列；根据所述检测优先级序列和所述切换条件生成动态切换策略；创建所述相同屏幕状态与所述动态切换策略之间的对应关系以形成所述映射关系。
其中，用户可通过电子设备的交互界面进行设置操作，交互界面在设置时可实时显示用户当前握持姿势会遮挡的天线，进而使用户得知用户在使用常用的握持方式握持电子设备时会遮挡的天线，进而根据得到的情况设置检测优先级。
可见，本示例中，用户可自定义设置检测优先级，提高了电子设备的智能性，同时电子设备根据上述检测优先级进行天线的检测和切换操作时，提高了天线切换的效率，避免了不必要的资源浪费，例如电子设备的电量和天线执行检测操作过程的损耗。
在一个可能的示例中，所述电子设备按照所述动态切换策略检测除当前启用的天线之外的至少一根天线的通信质量，并在所述通信质量满足所述切换条件时执行天线切换操作以避免或者降低所述电磁干扰，包括：电子设备确定当前处理的天线是否为最后一根待检测的天线；若否，则检测所述当前处理的天线的通信质量，并检测所述通信质量是否满足所述切换条件；若满足，则执行天线切换操作；若不满足，则更新所述当前处理的天线为下一根待检测的天线，所述下一根待检测的天线为所述检测优先级序列中所述当前处理的天线的下一个根天线；若是，则检测所述当前处理的天线的通信质量，并检测所述通信质量是否满足所述切换条件；若满足，则执行天线切换操作；若不满足，则执行跳频操作。
其中，当电子设备根据动态切换策略执行检测操作时，根据检测优先级序列依次进行检测，当轮到所述当前启用的天线时则跳过，检测所述检测优先级序列中的下一根天线。
举例来说，当前启用的天线在检测优先级序列中排在第二位，电子设备根据所述检测优先级序列确定排在检测优先级序列第一位的天线为当前处理的天线，判断排在检测优先级序列第一位的天线不是最后一根待检测的天线，则检测排在检测优先级序列第一位的天 线的通信质量，若通信质量满足切换条件则结束检测操作，执行天线切换操作。若不满足，根据检测优先级序列应检测所述当前启用的天线，则跳过；检测排在检测优先级序列第三位的天线，确定不是最后一根待检测的天线，则检测排在检测优先级序列第三位的天线的通信质量，若通信质量满足切换条件则结束检测操作，执行天线切换操作。若不满足，根据检测优先级序列应检测排在第四位的天线，确定是最后一根待检测的天线，检测通信质量，若通信质量满足切换条件则执行天线切换操作。若不满足，则执行跳频操作。
可见，本示例中，电子设备可根据检测优先级依次检测天线的通信质量，若天线的通信质量满足切换条件则执行天线切换操作；若不满足，则检测下一根天线；无需总是检测所有的天线，避免了资源的浪费，提高了天线切换的效率和电子设备的智能性。
在一个可能的示例中，所述电子设备还包括：应用处理器AP和调制解调器modem，所述检测所述摄像头与所述射频系统是否发生电磁干扰，包括：电子设备通过所述调制解调器modem获取第一频率的至少一个检测值，通过所述应用处理器AP获取第二频率的至少一个检测值，所述第一频率为所述射频系统的通信频率，所述第二频率为所述摄像头的锁相环PLL频率；通过所述应用处理器AP向所述调制解调器modem发送所述第二频率的至少一个检测值；通过所述调制解调器modem接收所述第二频率的至少一个检测值；所述调制解调器modem根据所述第一频率的至少一个检测值和所述第二频率的至少一个检测值确定所述电子设备的射频系统与显示屏是否发生电磁干扰。
在一个可能的示例中，所述电子设备还包括：应用处理器AP和调制解调器modem，所述检测所述摄像头与所述射频系统是否发生电磁干扰，包括：通过所述调制解调器modem获取第一频率的至少一个检测值，通过所述应用处理器AP获取第二频率的至少一个检测值，所述第一频率为所述射频系统的通信频率，所述第二频率为所述摄像头的锁相环PLL频率；通过所述调制解调器modem向所述应用处理器AP发送所述第一频率的至少一个检测值；通过所述应用处理器AP接收所述第一频率的至少一个检测值；所述应用处理器AP根据所述第一频率的至少一个检测值和所述第二频率的至少一个检测值确定所述电子设备的射频系统与显示屏是否发生电磁干扰。
