The following describes embodiments of the present application in detail.
Referring to fig. 2, fig. 2 is a schematic flowchart of an electromagnetic interference adjusting method disclosed in an embodiment of the present application, which is applied to the electronic device described in fig. 1, where the electronic device includes a display screen and a modem, and the electromagnetic interference adjusting method includes the following steps:
and S201, when the electronic equipment detects uplink data transmission, acquiring the working frequency of the Modem and the current first working frequency of a mobile processor interface (MIPI) of the display screen.

And S202, if the electronic equipment detects that the difference value between the working frequency of the Modem and the first working frequency is within a preset range, determining that the electronic equipment is interfered.
The preset range is self-determined by a factory manufacturer, and the difference may be 0, that is, the operating frequency of the Modem is the same as the first operating frequency, which is not limited herein.
S203, the electronic device acquires a first antenna which is currently started by the Modem.
Wherein, the Modem and the antenna have one-to-many correspondence.
And S204, the electronic equipment inquires a preset mapping relation set and acquires a first interference frequency list corresponding to the first antenna, wherein the mapping relation set comprises a corresponding relation between the antenna and the interference frequency list, and the interference frequency list comprises the working frequency point of the MIPI and the interference level of the working frequency point.
The correspondence relationship may be one-to-one, one-to-many, and many-to-many, and is not limited uniquely here.
S205, the electronic device determines a target antenna according to the first interference frequency list and the first working frequency.
S206, the electronic equipment switches the first antenna to the target antenna.
It can be seen that, in the method for adjusting electromagnetic interference and the related product described in this embodiment of the present application, first, when the electronic device detects uplink data transmission, an operating frequency of a Modem and a current first operating frequency of a MIPI of a mobile processor interface of a display screen are obtained, then, if a difference between the operating frequency of the Modem and the first operating frequency is detected within a preset range, it is determined that the electronic device is interfered, then, a first antenna currently enabled by the Modem is obtained, then, a preset mapping relationship set is queried, a first interference frequency list corresponding to the first antenna is obtained, then, a target antenna is determined according to the first interference frequency list and the first operating frequency, and finally, the first antenna is switched to the target antenna. Therefore, when the electronic device detects that the display screen MIPI interferes with the Modem, the transmitting antenna can be dynamically switched to reduce or eliminate interference through the working frequency of the MIPI and the interference list corresponding to the working frequency, so that the electronic device keeps the best signal quality, and the intelligence and the stability of the electronic device in electromagnetic interference adjustment are improved.
In one possible example, the determining, according to the first operating frequency, a target antenna corresponding to a target interference frequency list includes: the electronic equipment detects whether interference frequency lists except the first interference frequency list in the mapping relation set comprise the first working frequency; if so, selecting a second interference frequency list with the lowest interference level of the first working frequency, and acquiring a second antenna corresponding to the second interference frequency list, wherein the second antenna is a target antenna; if not, determining at least one third interference frequency list not including the first working frequency, determining a target third interference frequency list in the at least one third interference frequency list, and acquiring a third antenna corresponding to the target third interference frequency list, wherein the third antenna is a target antenna.
The manner of the interference level may be represented by "A, B, C" or the like, or by "1, 2, 3" or the like, and is not limited herein.
Wherein the at least one third list of interfering frequencies includes a plurality of MIPI interfering frequencies corresponding to the first operating frequency.
Therefore, in this example, the electronic device adopts different antenna adjustment modes under two different conditions, so that the integrity and flexibility of electromagnetic interference adjustment are improved.
In one possible example, the determining the target third list of interfering frequencies in the at least one third list of interfering frequencies comprises: the electronic equipment acquires an interference total value of each interference frequency list in the at least one third interference frequency list, wherein the interference total value is the sum of interference levels of each interference frequency in the interference frequency list; and selecting the third interference frequency list with the minimum interference total value as a target third interference frequency list.
Optionally, an antenna corresponding to each third interference list in the at least one third interference frequency list is obtained; obtaining the distance between at least one antenna and the MIPI of the display screen; and selecting the antenna with the shortest distance as the target antenna.
Therefore, in this example, the electronic device obtains the interference degree corresponding to each antenna by calculating the total interference value, and further performs uplink data transmission by selecting the antenna with the lowest interference degree, so that the electronic device maintains the best signal quality, and the intelligence and stability of the electronic device in the adjustment of electromagnetic interference are improved.
In one possible example, after the determining a target antenna from the first interference frequency list and the first operating frequency, the method further comprises: the electronic equipment acquires the current holding posture and determines whether the position of the target antenna is shielded or not; if not, selecting the target antenna for switching; or if so, adjusting the first working frequency of the MIPI.
The holding gesture is a position where a user's finger contacts the electronic device, a position where the user's finger presses the screen of the electronic device, a horizontal and vertical screen state of the electronic device, and the like, and is not limited herein.
The holding gesture can be acquired through an infrared sensor or acquired through a pressure sensor, if the holding gesture is detected through the infrared sensor, and if the acquired image is in a preset antenna area, the current antenna position is judged to be shielded.
Therefore, in this example, after the electronic device determines the target antenna, in order to avoid the situation that the quality of data transmission is reduced after the antenna is shielded when the antenna is switched, shielding detection for the position of the target antenna is started, the mode of switching the antenna can be adjusted in time, and the flexibility and the intelligence of electromagnetic interference adjustment are improved.
In one possible example, after the determining a target antenna from the first interference frequency list and the first operating frequency, the method further comprises: if the electronic equipment detects that the target antenna does not exist, searching a target MIPI working frequency with the lowest working frequency comparison value with the working frequency of the Modem in at least one preset MIPI working frequency; and switching the first working frequency to a target MIPI working frequency.
The comparison value may be a difference between the MIPI operating frequency and the operating frequency of the Modem, that is, the larger the difference is, the lower the comparison value is.
Optionally, in at least one operating frequency of the MIPI, according to a preset correspondence between the operating frequency of the MIPI and an interference frequency list, a first interference frequency list corresponding to the first operating frequency is determined by the Modem, where the first interference frequency list includes a plurality of MIPI interference frequencies corresponding to the first operating frequency.
Therefore, in this example, when the electronic device cannot find an antenna that meets the requirement, that is, it is determined that the current operating frequency of the MIPI interferes with the current uplink data transmission operation, the MIPI frequency modulation is adopted, and a target frequency that does not interfere with or interferes with the antenna with the current operating frequency of the Modem is selected, which is beneficial to intelligence and flexibility of the electronic device in adjusting the electromagnetic interference.
Consistent with the above, fig. 3 is a schematic flowchart of an electromagnetic interference adjustment method disclosed in an embodiment of the present application. The method for adjusting the electromagnetic interference is applied to the electronic equipment shown in fig. 1, wherein the electronic equipment comprises a display screen and a Modem, and the method for adjusting the electromagnetic interference comprises the following steps:
and S301, when the electronic equipment detects uplink data transmission, acquiring the working frequency of the Modem and the current first working frequency of a mobile processor interface (MIPI) of the display screen.
And S302, if the difference value between the working frequency of the Modem and the first working frequency is detected to be within a preset range, the electronic equipment is determined to be interfered.
And S303, the electronic equipment acquires the first antenna which is currently started by the Modem.
S304, the electronic equipment inquires a preset mapping relation set to obtain a first interference frequency list corresponding to the first antenna.
S305, the electronic device detects whether all interference frequency lists except the first interference frequency list in the mapping relationship set include the first operating frequency.
And S306, if so, the electronic equipment selects a second interference frequency list with the lowest interference level of the first working frequency, and acquires a second antenna corresponding to the second interference frequency list.
S307, the electronic equipment switches the first antenna to the second antenna.
It can be seen that, in the method for adjusting electromagnetic interference and the related product described in this embodiment of the present application, first, when the electronic device detects uplink data transmission, an operating frequency of a Modem and a current first operating frequency of a MIPI of a mobile processor interface of a display screen are obtained, then, if a difference between the operating frequency of the Modem and the first operating frequency is detected within a preset range, it is determined that the electronic device is interfered, then, a first antenna currently enabled by the Modem is obtained, then, a preset mapping relationship set is queried, a first interference frequency list corresponding to the first antenna is obtained, then, a target antenna is determined according to the first interference frequency list and the first operating frequency, and finally, the first antenna is switched to the target antenna.
