Abstract

The embodiment of the invention discloses an electromagnetic interference control method and a related device, and the method comprises the steps: detecting whether electromagnetic interference occursbetween a camera and a radio frequency system when detecting that the camera of electronic equipment is in an on state; If yes, detecting a screen state of the electronic equipment, and determining adynamic switching strategy of the four antennas according to the screen state; And detecting the communication quality of at least one antenna except the currently enabled antenna according to the dynamic switching strategy, and executing an antenna switching operation to avoid or reduce the electromagnetic interference when the communication quality meets the switching condition. The embodimentof the invention is beneficial to reducing or avoiding electromagnetic interference.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, and in particular to an electromagnetic interference control method and a related device. Background technique [0002] In daily life, when the camera of the electronic device and the radio frequency system work at the same time, the operating frequency of certain frequency bands of the radio frequency system may cause electromagnetic interference to the camera, resulting in blurred screen or freeze phenomenon when the camera previews and takes pictures. In the prior art, the shielding protection is added to the camera signal transmission line to reduce the electromagnetic interference of the radio frequency system to the camera. However, this method of improving the hardware will increase the cost of the electronic equipment and increase the volume of the electronic equipment, which is not enough Flexible and smart. Contents of the invention [0003] Embodiments of the ...
