In the embodiment of the application, by electrically connecting the radio frequency module 11 with the charging module 10, the radio frequency module 11 acquires a first interference channel when the radio frequency module is in a working time gap where the radio frequency module is not in communication with a base station and the charging module 10 is in a charging state; the first interference channel is a channel with charging interference; the method comprises the steps that when the radio frequency module 11 is in the working time of communicating with the base station and the charging module 10 is in the charging state, the current channel of the radio frequency module 11 is obtained, and when the current channel belongs to the first interference channel, the charging module 10 is controlled to execute interference reduction operation, so that the interference of the charging module 10 on the radio frequency module 11 is reduced, the sensitivity of the radio frequency module 11 under the current channel is improved, the conversation quality and the downloading speed of the electronic equipment can be improved, and the user experience is improved. In addition, the first interference channel is acquired from the plurality of standby channels, so that judgment basis is made for avoiding charging interference, and the problem of charging interference under different scenes is solved.

Referring to fig. 2, a schematic structural diagram of another electronic device according to an embodiment of the present application is shown, and as shown in fig. 2, the electronic device may further include: the blocking module 12 is arranged between the radio frequency module 11 and the charging module 10, and the blocking module 12 is electrically connected with the radio frequency module 11 and the charging module 10 respectively; the blocking module 12 may be configured to block a voltage signal of the charging module 10 to obtain a blocking voltage signal, and access the blocking voltage signal to the radio frequency module 11.
Specifically, the blocking module 12 may be connected between the battery 101 and the charging control sub-module 102 to block the voltage signal of the charging module 10, filter the dc signal therein, obtain a blocking voltage signal with the dc signal filtered, and access the blocking voltage signal to the radio frequency module 11. So as to prevent the direct current signal in the voltage signal of the charging module 10 from damaging the radio frequency module 11, and improve the service life of the radio frequency module 11.

In some optional embodiments of the application, the electronic device may further include a switch module 13, one end of the switch module 13 is electrically connected to the charging module 10, and the other end of the switch module 13 is electrically connected to the radio frequency module 11; the control module is electrically connected with the switch module 13; in the case that the radio frequency module 11 is in an operating time interval when not communicating with the base station, and the charging module 10 is in a charging state, the control module may be configured to control the switch module 12 to close to determine the first interference channel; under the condition that the radio frequency module 11 is in the working time of communicating with the base station and the charging module 10 is in the charging state, the control module may be configured to control the switch module 12 to be turned off to isolate the charging module 10 from the radio frequency module 11.
Specifically, the working time of the radio frequency module 11 in communicating with the base station may be specifically a state that the radio frequency module 11 resides on some channel and needs to use the channel for radio frequency communication. The working time interval when the radio frequency module 11 is not in communication with the base station may specifically be: the rf module 11 is in an operating time interval, and does not need to perform rf communication with the base station.
In practical applications, when the rf module 11 is in a working time gap where no communication with the base station is performed and the charging module 10 is in a charging state, the switch module 12 may be controlled to be turned on, so that the voltage signal of the charging module 10 may sequentially pass through the dc blocking module 12 and the switch module 13 and finally reach the rf module 11. Since the rf module 11 is in the working time gap when the rf module 11 is not in communication with the base station, at this time, under the condition that the voltage signal of the charging module 10 is accessed to the rf module 11, the rf module 11 may determine the first interference signal according to the voltage signal of the charging module 10.
In practical application, when the radio frequency module 11 is in a working time of communicating with the base station and the charging module 10 is in a charging state, the switch module 12 may be controlled to be turned off to disconnect the electrical connection between the charging module 10 and the radio frequency module 11, isolate the charging module 10 and the radio frequency module 11, and prevent a voltage signal of the charging module 10 from accessing the radio frequency module 11 and interfering with signal transceiving of the radio frequency module 11.

In the embodiment of the present application, the detection of the first interference degree value can be realized by sharing the existing radio frequency transceiver 111 and the power detector 113 in the radio frequency module 11, and then, the first interference channel can be determined, so that the structure is simple, and the hardware cost is low.
In a specific application, the process of determining the first interference channel is as follows: when the rf module 11 is in a working time gap where no communication with the base station is performed and the charging module 10 is in a charging state, the switch module 12 is closed, the voltage signal of the charging module 10 is dc-blocked by the dc-blocking module 12, and then enters the power detector 113 and the rf receiving path B through the switch module 12, and finally enters the rf transceiver 111, and the rf transceiver 111 can detect the power intensity falling into the current channel and determine the first interference range value of the rf module 11 on the current channel. Then, the radio frequency transceiver 111 may switch the detection circuit to other candidate channels, and sequentially detect the first interference degree value (i.e., the charging interference strength) on each candidate channel according to the above method, as a summary table of the interference situation in the current charging scenario. The summary table is referenced below:
in practical applications, the first interference channel may be determined from each of the candidate channels according to the first interference degree value (i.e. the summary table) of each of the candidate channels. Specifically. The first interference channel is a channel of which the first interference level value (i.e., the charging interference strength) is greater than a preset value (e.g., -40 dBm). In this charging scenario, when the current channel is the first interference channel, it indicates that the strength of the charging interference is large, and the normal communication of the radio frequency module 11 is already affected, and at this time, the charging module 10 needs to be controlled to perform the interference reduction operation.
In the embodiment of the application, through the electrical connection between the charging module 10 and the radio frequency module 11, the radio frequency module 11 can conveniently obtain the first interference channel from the plurality of standby channels in different charging scenes, so as to make a judgment basis for avoiding charging interference and improve the problem of charging interference in different scenes.
In practical application, after charging is started, the electronic device can respectively perform at least one detection of the charging interference condition in a low-power scene and a high-power scene according to the magnitude of the charging current, so as to ensure that all charging scenes are covered, and improve the charging interference problem in different scenes.
Specifically, controlling the charging module 10 to perform the interference reduction operation may specifically include: reducing the charging current of the charging module 10; alternatively, the switching frequency of the charging module 10 is adjusted. In practical application, the charging current of the charging module 10 is reduced, so that the interference intensity of the charging module 10 can be reduced, and further, the purpose of reducing charging disturbance can be achieved. By adjusting the switching frequency of the charging module 10, the frequency band of the radio frequency module 11 with serious charging interference can be changed, the interference condition of the current channel is improved, and the purpose of reducing charging interference is achieved.
In practical applications, the charging signal generated by the charging module 10 during the charging process usually falls in the radio frequency receiving frequency band in a frequency doubling manner to form an interference signal. For example, the clock signal of the switching circuit of the charging module 10 (related to the switching frequency of the charging module 10) is typically about 1MHz, and by multiplying the frequency to higher harmonics, these multiplied channels form the first interference signal. By modifying the switching frequency of the charging module 10, the situation of charging interference on the channel and the distribution of the first interference channel can be changed, so that the current channel is not a signal with serious charging interference, the interfered situation of the current channel is improved, and the purpose of reducing charging interference is achieved.

In addition, the first interference channel is acquired from the plurality of standby channels, so that judgment basis is made for avoiding charging interference, and the problem of charging interference under different scenes is solved.

In this embodiment, since the radio frequency module 11 is electrically connected between the battery 101 and the charging control submodule 102, when the radio frequency module 11 is in a working time gap where communication with the base station is not performed and the charging module 10 is in a charging state, a voltage signal of the charging module 10 may be transmitted to the radio frequency module 11, and the radio frequency module 11 may determine, according to the voltage signal of the charging module 10, a first interference channel where charging interference exists.

In this embodiment of the application, when the current channel belongs to the first interference channel, it may be considered that the radio frequency module 11 is greatly interfered by the charging module 10 when performing radio frequency communication in the current channel. At this time, the charging module 10 may be controlled to perform an interference reduction operation to reduce interference of the charging module 10 to the radio frequency module 11 during radio frequency communication in the current channel, and improve sensitivity of the radio frequency module 11 in the current channel, so that call quality and download rate of the electronic device may be improved, and user experience may be improved.

Specifically, the working time of the radio frequency module 11 for communicating with the base station may be a state in which the radio frequency module 11 resides on some channel and needs to use the channel for radio frequency communication. The working time interval of the radio frequency module 11 not communicating with the base station may specifically be: the rf module 11 is in an operating time interval, and does not need to perform rf communication with the base station.
In practical applications, when the rf module 11 is in a working time gap where no communication with the base station is performed and the charging module 10 is in a charging state, the switch module 12 may be controlled to be turned on, so that the voltage signal of the charging module 10 may sequentially pass through the dc blocking module 12 and the switch module 13 and finally reach the rf module 11.

Then, the rf transceiver 111 may switch the detection circuit to other candidate channels, and sequentially detect the first interference range value on each candidate channel according to the above-mentioned method.
Substep S12: and determining a first interference channel from each alternative channel according to the first interference degree value of each alternative channel.
In practical applications, the first interference channel may be determined from each of the candidate channels according to the first interference degree value (i.e. the summary table) of each of the candidate channels. Specifically. The first interference channel is a channel of which the first interference level value (i.e., the charging interference strength) is greater than a preset value (e.g., -40 dBm). In this charging scenario, when the current channel is the first interference channel, it indicates that the strength of the charging interference is large, and the normal communication of the radio frequency module 11 is already affected, and at this time, the charging module 10 needs to be controlled to perform the interference reduction operation.
