请参阅图3，图3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；如图所示，本电磁干扰控制方法包括：
步骤301，电子设备在检测到针对目标投屏设备的投屏请求时，启动无线高保真Wi-Fi模块；
具体实现中，所述电子设备可以在检测到针对目标投屏设备的投屏请求时启动无线高保真Wi-Fi模块；也可以是在检测到存在投屏请求时启动无线高保真Wi-Fi模块。
步骤302，所述电子设备搜索并接入目标无线网络，所述目标无线网络连接有所述目标投屏设备；
其中，所述电子设备与无线热点进行通信时，路由器会选择不同的通信信道进行数据传输，每个通信信道均对应协议约定的频域资源(如全球移动通信系统(Global System for Mobile Communication，GSM)频段、长期演进(Long Term Evolution，LTE)B8/B20/B28频段等)，且由相关通信协议可知，电子设备在执行不同的业务过程时，可以在同一业务处理时段使用一个或多个不同的通信信道。
步骤303，所述电子设备检测所述Wi-Fi模块与所述电子设备的显示屏的移动行业处理器接口MIPI是否发生电磁干扰；
其中，显示屏的MIPI频率可以根据芯片能力支持不同频率或频段，如频率514.5MHz、频率512.5MHz。Wi-Fi模块有不同信道，不同信道的工作频率不一样，与显示屏移动行业处理器接口MIPI频率之间产生的干扰也不一样。
步骤304，所述电子设备在检测到发生电磁干扰时，输出第一提示信息，并熄灭所述显示屏，以及执行投屏操作，所述第一提示信息用于表示所述电子设备正在执行熄屏投屏操作。
其中，电子设备检测到电磁干扰时，输出第一提示信息提示用户电子设备将熄屏并在后台进行投屏操作，避免熄屏操作过于突兀。同时，在检测到干扰时熄屏进行投屏，能避免显示屏和Wi-Fi模块产生干扰造成投屏不成功。
可以看出，本申请实施例中，电子设备在检测到针对目标投屏设备的投屏请求时，首先启动无线高保真Wi-Fi模块；然后搜索并接入目标无线网络，所述目标无线网络连接有所述目标投屏设备；再检测所述Wi-Fi模块与所述电子设备的显示屏的移动行业处理器接口MIPI是否发生电磁干扰；最后在检测到发生电磁干扰时，输出第一提示信息，并熄灭所述显示屏，以及执行投屏操作，所述第一提示信息用于表示所述电子设备正在执行熄屏投屏操作。可见，电子设备在检测到投屏请求时，且检测Wi-Fi模块与所述显示屏移动行业处理器接口MIPI发生电磁干扰时，熄灭显示屏，在后台执行投屏操作，避免了Wi-Fi模块 与所述显示屏移动行业处理器接口MIPI发生电磁干扰，影响投屏成功率，从而提高投屏场景中通信的稳定性。
在一个可能的示例中，所述检测所述Wi-Fi模块与所述电子设备的显示屏的移动行业处理器接口MIPI是否发生电磁干扰，包括：获取第一频率的至少一个检测值和第二频率的检测值，所述第一频率为所述Wi-Fi模块的通信频率，所述第二频率为所述显示屏移动行业处理器接口MIPI的工作频率；通过预设置的干扰信道列表确定所述电子设备的Wi-Fi模块与显示屏移动行业处理器接口MIPI是否发生电磁干扰，所述预设置的干扰信道列表包括显示屏移动行业处理器接口MIPI的不同工作频率对不同信道产生的干扰信息。
其中，预设置的干扰信道列表包括显示屏MIPI的不同工作频率对不同Wi-Fi信道的干扰大小和干扰等级。通过预设置的干扰信道列表，将第二频率的检测值与干扰信道列表的第一频率的检测值逐个比对，若存在干扰的频率，则确定电磁干扰，若不存在，则确定无电磁干扰。一般来说，无线路由器有1～13信道可选择，表1只示例性列出部分信道；MIPI频率为临时定义的频率，在具体实现中会根据实际情况调整。如表1所示的干扰信道列表。表1：
MIPI频率 信道1 信道2 信道3 信道4 信道5 信道6 信道7
512.5M干扰大小 2db 4db 3～4db 6db 5db 0db 5db
514.5M干扰大小 2db 3～4db 2db 4db 3db 1db 4db
516.5M干扰大小 3db 5db 3db 4db 5db 2db 4db
例如，当电子设备使用信道6，第二频率(MIPI频率)的检测值为514.5M时，根据表1，其干扰大小为1db，只需将MIPI频率跳频为512.5M就能实现干扰最小。当电子设备使用信道5，第二频率(MIPI频率)的检测值为512.5M时，只需将信道5切换为信道6就能实现干扰最小。当电子设备使用信道5，第二频率(MIPI频率)的检测值为514.5M时，根据表1，其干扰大小为3db，需将MIPI频率跳频为512.5M，将信道5切换为信道6实现干扰最小。
具体实现中，电子设备获取第一频率的至少一个检测值和第二频率的检测值可以是电子设备控制Wi-Fi模块检测频率信息，并上报所有信道信息给AP。电子设备控制所述AP接收所有信道信息，以及获取第二频率的检测值。AP结合本端检测到的显示屏MIPI频率判断电磁干扰，由于AP处理能力强，故而可以快捷高效的得到检测结果。还可以通过电子设备控制所述BP执行以下操作：获取所述第一频率的至少一个检测值；以及通过预设通道接收来自所述AP的所述第二频率的检测值；控制所述AP执行以下操作：获取所述第二频率的检测值，并向所述BP发送所述第二频率的检测值；BP根据所述至少一个检测值和所述第二频率的检测值，检测所述电子设备是否发生电子干扰。电子设备的AP和BP能够交互完成电磁干扰的检测，具体由BP采集第一频率的至少一个检测值，AP检测显示屏MIPI频率并发给BP，BP结合本端检测到的显示屏MIPI频率判断电磁干扰，由于AP与BP之间传输数据量小，延时低，实时性高，可以高效检测电磁干扰。
可见，本示例中，由于电子设备能够基于频率比对，快速确定显示屏MIPI当前使用的频率是否会与第一频率中的任意一个检测值发生电磁干扰，从而可以基于实时检测值快速定位电磁干扰场景，全面、准确的对电磁干扰情况进行检测，提高检测准确度和全面性。
在一个可能的示例中，所述在检测到发生电磁干扰时，输出第一提示信息，并熄灭所述显示屏后，还包括：获取所述目标路由器的至少一个信道的工作频率集合和所述第二频 率的可用频率范围或者可用频率值；根据所述干扰信道列表、第一频率的至少一个检测值和第二频率的检测值确定电磁干扰控制策略；当检测到亮屏时，根据所述电磁干扰控制策略执行干扰控制操作以降低或避免所述显示屏移动行业处理器接口MIPI对所述射频系统的电磁干扰。
其中，根据干扰信道列表中产生干扰最小的工作频率和显示屏移动行业处理器接口MIPI频率值，所述工作频率集合和可用频率范围或者可用频率值确定电磁干扰控制策略。
具体实现中干扰控制策略还可以通过预设置确定。
可见，本示例中，电子设备熄屏后除了执行投屏操作，还根据获取的目标路由器的至少一个信道的工作频率集合和所述第二频率的可用频率范围或者可用频率值确定干扰控制策略，在检测到亮屏时执行干扰控制操作，避免了亮屏后再产生电磁干扰，提高电子设备信息交互的稳定性。
在一个可能的示例中，所述电磁干扰控制策略包括：根据所述干扰信道列表确定所述第二频率的目标频率值，所述目标频率值为对所述目标路由器使用的信道的工作频率干扰最小的显示屏移动行业处理器接口MIPI频率；将所述显示屏移动行业处理器接口MIPI频率调整为所述目标频率值。
其中，根据干扰信道列表确定对目标路由器当前使用的信道的工作频率产生干扰最小的显示屏移动行业处理器接口MIPI频率，对显示屏移动行业处理器接口MIPI频率执行跳频操作。
可以理解的是，显示屏MIPI频率的目标频率值的确定策略可以是多种多样的，具体约束条件可以包括显示屏芯片能力支持，此处不做唯一限定。
可见，本示例中，电子设备确定发生电磁干扰后，根据对当前路由器信道的干扰信息和第二频率的可用频率范围或者可用频率值确定跳频的目标频率值，并在亮屏时调整显示屏MIPI频率为所述目标频率值，处理过程便捷高效，延时低，稳定性高。
在一个可能的示例中，所述电磁干扰控制策略包括：根据所述干扰信道列表确定目标信道，所述目标信道为所述显示屏熄屏前的工作频率对所述目标路由器的至少一个无线信道干扰最小的无线信道；根据所述目标信道执行信道切换。
其中，根据干扰信道列表确定显示屏熄屏之前的工作频率所对应的干扰最小的目标信道，在亮屏时与路由器协商信道切换来规避干扰。
具体实现中，电子设备确定的目标信道频率应该很少或不会与显示屏MIPI频率发生电磁干扰。
