Please refer to FIG. 2. FIG. 2 is a schematic flowchart of an electromagnetic interference control method provided by an embodiment of the present application, which is applied to the electronic device shown in FIG. 1. As shown in the figure, the control method includes:

S201, when it is detected that the camera of the electronic device is turned on, detect whether electromagnetic interference occurs between the camera and the radio frequency system of the electronic device.

Among them, electromagnetic interference refers to the interference to the camera when the camera and the radio frequency system work at the same time, when the radio frequency system is in a certain working frequency band. Whether electromagnetic interference occurs between the camera and the radio frequency system of the electronic device can be detected by dynamic comparison. For example, the current operating frequency of the camera and the current operating frequency of the radio frequency system can be directly obtained, if the two can match according to preset rules. , it is considered that electromagnetic interference has occurred between the radio frequency system and the camera, and a static look-up table can be used to detect whether electromagnetic interference occurs between the camera and the radio frequency system of the electronic device. For example, a list of electromagnetic interference frequencies is pre-established in the electronic device. , to obtain the current working frequency of the radio frequency system. If the working frequency is in the electromagnetic interference frequency list, it is considered that electromagnetic interference has occurred between the radio frequency system and the camera.

S202, if yes, determine the currently enabled first antenna, and detect whether the first antenna is the antenna farthest from the camera.

Wherein, the currently enabled first antenna is the antenna currently performing radio frequency transmission. When electromagnetic interference between the camera and the radio frequency system of the electronic device is detected, the currently enabled first antenna is determined, and the first antenna is detected. Whether it is the antenna farthest from the camera.

S203, if not, send a first preset instruction to the Modem through the AP.

Wherein, S203 is to send a first preset command to the Modem through the AP when it is detected that the first antenna is not the antenna farthest from the camera, where the first preset command includes notifying the The Modem performs an antenna switching operation.

S204, receiving the first preset instruction through the Modem, and performing an antenna switching operation to reduce or avoid electromagnetic interference between the camera and the radio frequency system.

The operation of antenna switching performed by the Modem means that the Modem switches the current radio frequency transmission from the current working antenna, that is, the first antenna, to the second antenna that does not cause electromagnetic interference to the camera or has less electromagnetic interference to the camera. The Modem may perform the antenna switching operation according to a preset strategy, wherein the preset strategy may be performing the antenna switching operation according to the distance between the antenna and the camera, and the preset strategy may also be performing the antenna switching operation according to the influence of the antenna on the camera, This embodiment does not limit the preset policy.

It can be seen that, in the embodiment of the present application, when the electronic device detects that the camera of the electronic device is turned on, it detects whether electromagnetic interference occurs between the camera and the radio frequency system of the electronic device; an antenna, and detect whether the first antenna is the antenna farthest from the camera; if not, send a first preset command to the Modem through the AP; receive the first preset command through the Modem An instruction is provided to perform an antenna switching operation to reduce or avoid electromagnetic interference between the camera and the radio frequency system. It can be seen that the electronic device of the embodiment of the present application can reduce or avoid the electromagnetic interference between the radio frequency system and the camera by performing the antenna switching operation, thereby improving the flexibility and intelligence of the electronic device for electromagnetic interference control.

In a possible example, the acquiring the user profile information of the target application includes: performing an antenna switching operation to reduce or avoid electromagnetic interference between the camera and the radio frequency system, including: extracting from the Screen one second antenna except the first antenna among the four antennas; switch to the second antenna, and fix the unique correspondence between the radio frequency system and the second antenna.

Wherein, selecting a second antenna other than the first antenna from the four antennas refers to selecting one antenna from the antennas other than the current working antenna that will not cause electromagnetic interference to the camera or reduce electromagnetic interference to the camera. The interfering antenna acts as the target antenna. Fixing the unique correspondence between the radio frequency system and the second antenna refers to temporarily using the screened antenna as the only antenna for current radio frequency transmission.

It can be seen that in this example, the electronic device can temporarily fix the unique correspondence between the radio frequency system and the switched antenna after switching the antenna, so that the electromagnetic interference control is more stable.

In a possible example, selecting a second antenna other than the first antenna from the four antennas includes: selecting the antenna with the farthest distance from the camera from the remaining three antennas as the target antenna.

Among them, the antenna with the farthest distance from the camera is selected from the remaining 3 antennas as the target antenna, and the electronic device can be manually pre-selected and set, and the antenna that is farthest from the camera can be directly preset in the electronic device as the target antenna. , the electronic device directly locates it, or the electronic device directly obtains the distance data between the remaining three antennas and the camera, and after comparison, selects the antenna with the largest value as the target antenna.

It can be seen that in this example, the electronic device can control the electromagnetic interference by screening the target antenna according to the distance between the antenna and the camera, which increases the flexibility of electromagnetic interference control.

In a possible example, screening a second antenna other than the first antenna from the four antennas includes: determining an antenna that is not held among the remaining three antennas; When the number of antennas holding the antenna is 0, the antenna farthest from the camera is used as the target antenna; when the number of antennas not holding the antenna is 1, the antenna is used as the target antenna; When the number of antennas that are not held is 3, the antenna farthest from the camera is used as the target antenna; when the number of antennas that are not held is 2, when the two antennas are connected to the camera When the distances are different, the antenna farthest from the camera is used as the target antenna; or, when the distances between the two antennas and the camera are the same, the antenna with the least interference to the camera is selected as the target antenna.

Among them, the "not being held" means that the transmitting area of the antenna is not blocked by the user's palm, and the sensor detects the antenna that is not held among the remaining three antennas. When the remaining three antennas are all held, the distance is selected. The antenna farthest from the camera is used as the target antenna, because, under the same conditions, the farther the antenna used for radio frequency transmission is from the camera, the smaller the electromagnetic interference to the camera.

It can be seen that, in this example, the electronic device can screen the target antenna according to the user's hand to control the electromagnetic interference, so that the electromagnetic interference control is more flexible.

In a possible example, selecting a second antenna other than the first antenna from the 4 antennas includes: selecting from the remaining 3 antennas that the distance from the camera is the farthest and is not connected to the camera. The held antenna serves as the target antenna.

Among them, the antenna that is farthest away from the camera and not held from the remaining three antennas is selected as the target antenna. It can be determined by first determining the antenna that is farthest from the camera among the remaining antennas, and then judging whether the antenna is held. Until the target antenna is determined, it is also possible to first determine the antennas that are not held by the remaining three antennas, and then select the antenna that is farthest from the camera as the target antenna from the antennas that are not held. When the remaining 3 antennas are all held, select the antenna farthest from the camera as the target antenna.

It can be seen that in this example, the electronic device can control the electromagnetic interference by screening the target antenna according to the distance between the antenna and the camera, which increases the flexibility of electromagnetic interference control.

In a possible example, if it is detected that the first antenna is the antenna farthest from the camera, the operating frequency of the camera is adjusted to reduce or avoid electromagnetic interference between the camera and the radio frequency system .

Wherein, adjusting the working frequency of the camera may be an automatic refresh working frequency.

In a possible example, the detecting whether electromagnetic interference occurs between the camera and the radio frequency system of the electronic device includes: detecting the current working frequency of the camera and the current working frequency of the radio frequency system; comparing the Whether the current working frequency of the camera is compatible with the current working frequency of the radio frequency system; or, obtain the current working frequency of the radio frequency system; query the preset electromagnetic interference frequency list of the camera, and determine whether the list contains The current operating frequency of the radio frequency system.

The adaptation may mean that the current working frequency of the radio frequency system completely coincides with or is close to the current working frequency of the camera, and the adaptation may also mean that the frequency division of the current working frequency of the radio frequency system completely coincides with or is close to the current working frequency of the camera. Matching may also mean that the frequency multiplier of the current working frequency of the radio frequency system completely coincides with or is close to the current working frequency of the camera, and the closeness means that the frequency is within a preset difference range. The electromagnetic interference frequency list of the camera may include each operating frequency of the camera and the frequency multiplication or frequency division of each operating frequency.

In a possible example, the comparing the current working frequency of the camera with the current working frequency of the radio frequency system includes: sending the current working frequency of the radio frequency system to the AP through the Modem; The AP compares the current working frequency of the radio frequency system with the current working frequency of the camera; or, sends the current working frequency of the camera to the Modem through the AP; The current operating frequency of the camera is compared with the current operating frequency of the radio frequency system.

The comparison may be a direct comparison, that is, the current operating frequency of the camera is directly compared with the current operating frequency of the radio frequency system, and the comparison may also be an indirect comparison, which may be the camera The comparison between the current operating frequency, the frequency division or frequency multiplication of the current operating frequency and the current operating frequency of the radio frequency system, the frequency division or frequency multiplication of the current operating frequency, except for direct comparison.
