The electronic device may be a smart phone, a tablet computer, a palmtop computer, a notebook computer, or a desktop computer and other devices.

Please refer to FIG. 1 , which is a schematic flowchart of a method for processing radio frequency interference provided by an embodiment of the present application.

It should be noted that the radio frequency interference processing method is specifically applied to an electronic device, the electronic device includes at least two radio frequency antennas and a wireless antenna, and the at least two radio frequency antennas include a main set radio frequency antenna and at least one diversity radio frequency antenna . The main antenna structure can be used to send and receive antenna signals, such as sending and receiving at least one of low-frequency (700-960MHz), mid-frequency (1710-2170MHz) and high-frequency (2300-2690MHz) signals. Decide. The diversity radio frequency antenna can receive signals in different frequency bands.

The specific process of the radio frequency interference processing method provided by the embodiment of the present application may be as follows:

201. Obtain a first working frequency band of the main set of radio frequency antennas.

It can be understood that the at least two radio frequency antennas include a main set radio frequency antenna and at least one diversity radio frequency antenna. Since the main set radio frequency antenna can transmit a signal in a certain frequency band, if the transmitted signal is different from the signal transmitted by other antenna structures. Radio frequency interference occurs when the frequency bands are closely spaced. The diversity RF antenna can only receive signals in a certain frequency band.

Among them, each radio frequency antenna in the electronic equipment can be used as the main set of radio frequency antennas to transmit and receive signals in a certain frequency band, but because the antenna structure of each radio frequency antenna is inconsistent, each radio frequency antenna is used as the main set of radio frequency antennas to send and receive signals. The frequency bands of the signals that can be sent and received are different.

Further, the electronic device may acquire the first working frequency band of the main set of radio frequency antennas to determine whether radio frequency interference will occur with the working frequency bands transmitted by other antenna structures.

202. Acquire a second working frequency band of the wireless antenna.

It should be noted that, the wireless antenna can be used to send and receive global positioning system signals and/or short-range communication signals. Such as sending and receiving GPS (Global Positioning System, global positioning system), WIFI (wireless network) 2.4G/5G signals.

The electronic device can obtain the second working frequency band of the wireless antenna to determine whether radio frequency interference will occur with the working frequency band transmitted by the main set of radio frequency antennas.

203. Determine whether the first working frequency band and the second working frequency band will interfere.

Wherein, when the frequencies between the first working frequency band and the second working frequency band are relatively close, radio frequency interference will occur, that is, when it is determined that the first working frequency band and the second working frequency band will cause interference, step 204 is performed; When the frequencies between the first working frequency band and the second working frequency band are not close enough, radio frequency interference will not occur, and the electronic device does not perform the switching operation of the main set of radio frequency antennas.

Specifically, the step of judging whether the first working frequency band and the second working frequency band will interfere may include:

(1) obtain the first end frequency of this first working frequency band, obtain the second end frequency of this second working frequency band;

(2) calculate the first absolute value of this first endpoint frequency and the second endpoint frequency difference;

(3) judging whether the first absolute value is less than a preset safety threshold;

Wherein, when it is determined that the first absolute value is less than the preset safety threshold, step (4) is performed; when it is determined that the first absolute value is not less than the preset safety threshold, step (5) is performed.

(4) It is determined that the first working frequency band and the second working frequency band will interfere;

(5) It is determined that the first working frequency band and the second working frequency band will not interfere.

Among them, since the first working frequency band and the second working frequency band are both an interval, the frequency of the end point (ie the extreme value, such as the maximum value and the minimum value) of the interval can be obtained correspondingly. For example, the first working frequency band is B41 (2496-2690MHz), the endpoint frequencies of the interval are 2496MHz and 2690MHz. Similarly, the second working frequency band is 2.4G of WiFi (2412-2482MHz), and the endpoint frequencies of the interval are 2412MHz and 2482MHz.

Further, the first absolute value of the difference between the first endpoint frequency and the second endpoint frequency is calculated. Since there are two first endpoint frequencies and two second endpoint frequencies, the first absolute value can include 4 an absolute value, for example, the first absolute value includes 14MHz, 84MHz, 208MHz, and 278MHz.

The preset safety threshold is a critical value for judging whether the first working frequency band and the second working frequency band will interfere. When it is judged that the first absolute value is less than the preset safety threshold value, it indicates that both the first working frequency band and the second working frequency band are both. The frequencies are relatively close, and step (4) is performed, and it is determined that the first working frequency band and the second working frequency band will interfere. When it is determined that the first absolute value is not less than the preset safety threshold, it means that the frequencies of the first working frequency band and the second working frequency band are far apart, and step (5) is performed. It is determined that the first working frequency band and the second working frequency band do not interfere.

204. Switch the main set radio frequency antenna.

Among them, when the frequencies between the first working frequency band and the second working frequency band are relatively close, radio frequency interference will occur, that is, when it is judged that the first working frequency band and the second working frequency band will interfere Antenna, that is to switch the main RF antenna to another RF antenna. Since the antenna structure of each RF antenna is different, the frequency band of the transmitted signal is also different. Switching the main RF antenna to another RF antenna can change the main RF antenna. The transmission frequency band of the antenna solves the problem of radio frequency interference between the main set of radio frequency antennas and wireless antennas.

Specifically, the step of switching the main set of radio frequency antennas may include:

(1) Select one diversity radio frequency antenna from the at least one diversity radio frequency antenna and determine it as the target diversity radio frequency antenna.

(2) Switch the main set radio frequency antenna to the diversity radio frequency antenna, and switch the target diversity radio frequency antenna to the main set radio frequency antenna.

In one embodiment, when the number of the diversity radio frequency antennas is one, the one diversity radio frequency antenna is directly determined as the target diversity radio frequency antenna. When the number of the diversity radio frequency antennas is not one, a diversity radio frequency antenna farthest away from the position of the wireless antenna can be selected and determined as the target diversity radio frequency antenna, or the working frequency band in each diversity radio frequency antenna can be obtained in turn, and the The diversity radio frequency antenna with the largest frequency interval from the working frequency band of the wireless antenna is determined as the target diversity radio frequency antenna.

Further, switching the current main set radio frequency antenna to a diversity radio frequency antenna, and at the same time switching the target diversity radio frequency antenna to the main set radio frequency antenna, and using the newly switched main set radio frequency antenna for signal transmission, can reduce the radio frequency interference with the wireless antenna. .

Specifically, the step of selecting a diversity radio frequency antenna from the at least one diversity radio frequency antenna and determining it as the target diversity radio frequency antenna may include:

(1.1) Obtain the frequency of the third end point in each diversity radio frequency antenna in turn;

(1.2) Calculate the second absolute value of the difference between the frequency of the second end point and the frequency of the third end point, select a diversity radio frequency antenna with the largest second absolute value, and determine the diversity radio frequency antenna with the largest second absolute value as the target Diversity RF Antenna.

Wherein, the frequency of the third end point in each diversity radio frequency antenna can be obtained in turn, and then the second absolute value of the frequency difference between the second end point and the third end point can be used to determine that the frequency interval with the second working frequency band of the wireless antenna is the largest The diversity radio frequency antenna is determined, and the second diversity radio frequency antenna with the largest absolute value is determined as the target diversity radio frequency antenna.

It can be seen from the above that the embodiment of the present application obtains the first working frequency band of the main set of radio frequency antennas; obtains the second working frequency band of the wireless antenna; judges whether the first working frequency band and the second working frequency band will interfere; When there is interference between the frequency band and the second working frequency band, switch the main RF antenna. In this way, when radio frequency interference between the working frequencies of the main set radio frequency antenna and the wireless antenna is detected, switching the main set radio frequency antenna of the electronic device can reduce the radio frequency interference of the electronic device.

The display method of the present application will be further introduced below on the basis of the methods described in the above embodiments. Referring to FIG. 2, the processing method of the radio frequency interference may include:

301. Acquire a first working frequency band of the main set of radio frequency antennas.

It should be noted that, in order to better describe this embodiment, as shown in FIG. 3 , the electronic device 10 integrates three radio frequency antennas and one wireless antenna as an example for illustration. The antenna 12 , the second radio frequency antenna 13 and the third radio frequency antenna 14 . The signal transmitted by the WiFi antenna 11 may be 2.4G (2412-2482MHz). The first radio frequency antenna 12 can transmit a low frequency band (700-960 MHz). The second radio frequency antenna 13 can transmit intermediate frequency signals (1710-2170 MHz). The third radio frequency antenna 14 can transmit high frequency signals (2496-2690 MHz). The third radio frequency antenna 14 serves as the main radio frequency antenna, and can transmit and receive signals. The first radio frequency antenna 12 and the second radio frequency antenna 13 are diversity radio frequency antennas and can receive signals. Specifically, other numbers of radio frequency antennas and wireless antennas may be included, and this example should not be taken as a limitation of the present invention.

The electronic device acquires the first working frequency band (2496-2690 MHz) of the main set of radio frequency antennas (ie, the third radio frequency antenna 14).

302. Obtain a second working frequency band of the wireless antenna.

The electronic device acquires the second working frequency band (2412-2482 MHz) of the wireless antenna (WiFi antenna).

303. Acquire the first end frequency of the first working frequency band, and obtain the second end frequency of the second working frequency band.

Among them, since the first working frequency band and the second working frequency band are both an interval, the end point (ie extreme value, such as the maximum value and the minimum value) frequency of the interval can be obtained correspondingly, and the first end point of the first working frequency band The frequencies are 2496MHz and 2690MHz. The second end frequencies of the second working frequency band are 2412MHz and 2482MHz.

304. Calculate the first absolute value of the difference between the first endpoint frequency and the second endpoint frequency.

Among them, since there are two frequencies of the first end point and two frequencies of the second end point, the corresponding first absolute values of the difference between the frequency of the first end point and the frequency of the second end point are calculated respectively, that is, 2496MHz minus 2412MHz , get 84MHz, subtract 2482MHz from 2496MHz, get 14MHz, subtract 2412MHz from 2690, get 278MHz, subtract 2482MHz from 2690MHz, get 208MHz. The first absolute value includes 4 values, which are 84MHz, 14MHz, 278MHz and 208MHz respectively. The larger the first absolute value is, the larger the frequency interval between the first working frequency band and the second working frequency band is, the smaller the interference is, and the smaller the first absolute value is, indicating that the first working frequency band and the second working frequency band are larger. The smaller the frequency separation of the operating frequency band, the greater the interference that occurs.

305. Determine whether the first absolute value is less than a preset safety threshold.

It should be noted that the preset safety threshold is a critical point for judging whether the first working frequency band and the second working frequency band interfere, such as 30MHz. When the first absolute value is less than the preset safety threshold, step 306 is executed. When the first absolute value is not less than the preset safety threshold, step 311 is executed.

The first absolute value of 84MHz, 14MHz, 278MHz and 208MHz is compared with the preset safety threshold of 30MHz, and it is found that the 14MHz is smaller than the 30MHz, and step 306 is executed.

306. Acquire the third endpoint frequency in each diversity radio frequency antenna in sequence.

Wherein, when it is determined that the first absolute value is less than the preset safety threshold, it means that the first working frequency band will cause radio frequency interference with the second working frequency band, and one needs to be selected from the first radio frequency antenna 12 and the second radio frequency antenna 13 RF antenna.

Specifically, the third end frequency band in each diversity radio frequency antenna is sequentially acquired, for example, the third end frequency of the first radio frequency antenna 12 is 700 MHz and 960 MHz. The third end frequencies of the second radio frequency antenna 13 are 1710MHz and 2170MHz.

307. Calculate the second absolute value of the difference between the frequency of the second end point and the frequency of the third end point, select a diversity radio frequency antenna with the largest second absolute value, and determine the diversity radio frequency antenna with the largest second absolute value as the target diversity radio frequency antenna.

The larger the frequency interval is, the smaller the radio frequency interference between the two antennas is. Therefore, the difference between the second end frequency of the WiFi antenna 2412MHz and 2482MHz and the third frequency of the first radio frequency antenna 12 of 700MHz and 960MHz is calculated. The second absolute values are 1712MHz, 1452MHz, 1782MHz, and 1522MHz, respectively. and the second absolute values of the difference between the second endpoint frequencies 2412MHz and 2482MHz of the WiFi antenna and the third frequencies 1710MHz and 2170MHz of the second RF antenna 13 , which are 702MHz, 242MHz, 772MHz and 312MHz, respectively. By comparing the second absolute value, the first radio frequency antenna 12 with the largest second absolute value is determined as the target diversity antenna.

308. Switch the main set radio frequency antenna to the diversity radio frequency antenna, and switch the target diversity radio frequency antenna to the main set radio frequency antenna.

Wherein, the main set radio frequency antenna that currently interferes with the wireless antenna is switched to the diversity radio frequency antenna, and at the same time, the target diversity radio frequency antenna, that is, the first radio frequency antenna 12, is switched to the main set radio frequency antenna. As well as reducing radio frequency interference between antennas.

309. Determine the relative positions of the wireless antenna and the main set of radio frequency antennas.

The electronic device determines the positions of the WiFi antenna 11 and the first radio frequency antenna 12 (the main radio frequency antenna) respectively.

310. Control the transmission direction of the signal transmitted by the wireless antenna to the main set radio frequency antenna, so as to reduce the interference of the signal sent by the wireless antenna to the main set radio frequency antenna.

Wherein, after determining the positions of the WiFi antenna 11 and the first radio frequency antenna 12 (main set radio frequency antenna), the electronic device controls the transmission direction of the signal transmitted by the WiFi antenna 11 to the first radio frequency antenna 12, that is, controls the WiFi antenna 11 The transmitted signal is not transmitted in the direction of the first radio frequency antenna 12 , so as to reduce the radio frequency interference of the signal sent by the WiFi antenna 11 to the first radio frequency antenna 12 .

311. It is determined that the first working frequency band and the second working frequency band will not interfere.

Wherein, when the first absolute value is not less than the preset safety threshold, it means that the frequency interval between the first working frequency band and the second working frequency band is relatively large, and it is determined that the first working frequency and the second working frequency will not interfere.

It can be seen from the above that the embodiment of the present application obtains the first working frequency band of the main set of radio frequency antennas; obtains the second working frequency band of the wireless antenna; judges whether the first working frequency band and the second working frequency band will interfere; When the frequency band and the second working frequency band interfere, the diversity antenna with the largest frequency interval from the second working frequency band of the wireless antenna is selected from the diversity radio frequency antennas as the main set radio frequency antenna. In this way, when radio frequency interference between the working frequencies of the main set radio frequency antenna and the wireless antenna is detected, switching the main set radio frequency antenna of the electronic device can reduce the radio frequency interference of the electronic device.

Further, by determining the positions of the wireless antenna and the main set of radio frequency antennas, the transmission direction of the signals of the wireless antenna is controlled to avoid the position of the main set of radio frequency antennas, which better reduces the radio frequency interference of electronic equipment.
