Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present invention are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the invention and should not be taken as limiting the invention with regard to other embodiments that are not detailed herein.
As will be described in detail below.
Referring to fig. 1, fig. 1 is a schematic flowchart of a radio frequency interference processing method according to an embodiment of the present invention, where the radio frequency interference processing method is applied to a terminal, and the process may include:
in step S101, when the terminal performs communication and charging, the communication frequency of the terminal is acquired.
It is understood that the execution subject of the embodiment of the present invention may be a terminal device such as a smart phone or a tablet computer.
For example, as communication technologies are continuously developed, communication frequency ranges available for terminals are increasingly wider. Currently, communication frequencies commonly used by terminals include various frequencies ranging from 700MHz frequency band to 2600MHz frequency band. However, with the increasing range of communication frequencies that can be used by a terminal, the radio frequency communication frequency of the terminal is susceptible to interference during communication. For example, when communication and charging are performed simultaneously, the operating frequency of the charging adapter is likely to cause interference with the communication frequency of the terminal.
In step S101 of the embodiment of the present invention, under the condition of performing radio frequency communication and charging simultaneously, the terminal may first acquire its current communication frequency.
In step S102, an operating frequency of a charging adapter connected to the terminal is obtained, where the charging adapter includes a frequency conversion device.
For example, after acquiring the communication frequency of the terminal, the terminal may acquire the operating frequency of the charging adapter connected thereto, and the charging adapter may include a frequency conversion device.
In step S103, it is determined whether there is interference between the operating frequency and the communication frequency.
For example, after acquiring the communication frequency of the terminal and the operating frequency of the charging adapter connected to the terminal, the terminal may determine whether interference occurs between the operating frequency and the communication frequency.
If it is determined that interference is not generated between the operating frequency and the communication frequency, the terminal may perform other operations, i.e., step S105.
If it is determined that interference is generated between the operating frequency and the communication frequency, step S104 is performed.
In step S104, if there is interference between the operating frequency and the communication frequency, a frequency conversion command is sent to the charging adapter to reduce the interference of the operating frequency of the charging adapter to the communication frequency, where the frequency conversion command is used to instruct the charging adapter to convert the operating frequency by using a frequency converter.
For example, if the terminal determines that the operating frequency of the charging adapter connected to the terminal may interfere with the communication frequency, the terminal may send a frequency conversion instruction to the charging adapter, where the frequency conversion instruction is used to instruct the charging adapter to convert the operating frequency using its frequency converter device, so as to reduce the interference of the operating frequency of the charging adapter with the communication frequency.
It should be noted that the operating frequency of the charging adapter of most terminals is 108MHz or higher, and the operating frequency (or its harmonic frequency) is liable to cause interference to the communication frequency of the low frequency band (for example, the communication frequency of the 700-900 MHz frequency band). According to the embodiment of the invention, when the working frequency of the charging adapter is judged to generate interference on the communication frequency of the terminal, the terminal sends a frequency conversion instruction to the charging adapter, and the instruction is used for instructing the charging adapter to convert the working frequency of the charging adapter. After the charging adapter converts the working frequency of the charging adapter, the working frequency of the charging adapter and the harmonic frequency of the charging adapter are changed, so that the interference of the working frequency of the charging adapter to the communication frequency can be effectively reduced.
As can be seen from the above, the radio frequency interference processing method provided in this embodiment may send the frequency conversion instruction to the charging adapter when the operating frequency used by the charging adapter may cause interference to the communication frequency, so that the charging adapter may convert the operating frequency thereof, thereby effectively reducing the interference of the charging adapter to the radio frequency communication of the terminal.
Referring to fig. 2, fig. 2 is another schematic flow chart of a radio frequency interference processing method according to an embodiment of the present invention, where the radio frequency interference processing method is applied to a terminal, and the flow chart may include:
in step S201, the terminal acquires a communication frequency for data reception when the terminal performs communication and charging.
For example, in the case of performing radio frequency communication and charging simultaneously, the terminal may first acquire a communication frequency currently used by the terminal for data reception.
It is understood that the communication frequency of the terminal includes an uplink communication frequency for signal transmission and a downlink communication frequency for data reception. When transmitting signals, the terminal uses a large power, so that uplink signals of the terminal are not easily interfered. Since the signal is attenuated during the transmission process, the strength of the signal received by the terminal is weak, that is, if the downlink communication frequency is interfered, the downlink signal is weakened, which affects the normal communication. Thus, in one embodiment, the terminal may only acquire the downlink communication frequency for data reception.
In step S202, the terminal acquires an operating frequency of a connected charging adapter, where the charging adapter includes a frequency conversion device.
For example, after acquiring the current downlink communication frequency of the terminal, the terminal may acquire the operating frequency of the charging adapter connected thereto. In an embodiment of the present invention, the charging adapter includes a frequency conversion device.
In step S203, the terminal identifies the harmonic frequencies of the predetermined order of the operating frequency, and calculates the frequency interval between each harmonic frequency and the communication frequency.
For example, after acquiring the operating frequency of the charging adapter, the terminal may determine a harmonic frequency of a preset order of the operating frequency, and calculate a frequency interval between each harmonic frequency and the communication frequency of the terminal.
In one embodiment, the predetermined order number is less than 50. For example, the number of the preset order includes 2 to 10, i.e., the terminal determines the harmonic frequencies of 2 th harmonic to 10 th harmonic. It is understood that harmonics of an excessively high order are substantially negligible, and thus the number of the preset order may be set to less than 50.
For example, the operating frequency of the terminal, which acquires the charging adapter connected to the terminal, is 108MHz, and the preset order is 2 times to 10 times. Then the 2 nd harmonic frequency to the 10 th harmonic frequency of the operating frequency are: 216MHz, 324MHz, 432MHz, 540MHz, 648MHz, 756MHz, 864MHz, 972MHz, 1080 MHz.
The terminal may then calculate the frequency separation of each higher harmonic frequency from the communication frequency. For example, the downlink communication frequency of the terminal is 869.2 MHz. Then, the frequency intervals between the 2 nd harmonic frequency to 10 th harmonic frequency of the operating frequency of the charging adapter and the downstream communication frequency are: 761.2MHz, 545.2MHz, 437.2MHz, 329.2MHz, 221.2MHz, 113.2MHz, 5.2MHz, 102.8MHz, 210.8 MHz.
In step S204, the terminal determines the frequency interval with the smallest value as the target frequency interval.
In step S205, the terminal determines whether the target frequency interval is smaller than a preset interval threshold.
For example, steps S204 and S205 may include:
after calculating the frequency interval between each harmonic frequency and the communication frequency of the terminal, the terminal may determine the frequency interval with the smallest value as the target frequency interval.
For example, the smallest value in the frequency interval between the 2 nd harmonic frequency to the 10 th harmonic frequency of the operating frequency of the charging adapter and the downstream communication frequency is 5.2MHz (corresponding to the 5 th harmonic frequency).
After determining the target frequency interval, the terminal may determine whether the target frequency interval is smaller than a preset interval threshold.
If the target frequency interval is less than the preset interval threshold, the process proceeds to step S206.
If the target frequency interval is greater than or equal to the preset interval threshold, the process proceeds to step S208.
In step S206, if it is determined that the target frequency interval is smaller than the preset interval threshold, the terminal determines that the harmonic of the operating frequency interferes with the communication frequency.
In step S207, the terminal sends a frequency conversion instruction to the charging adapter, where the frequency conversion instruction carries a preset variation value to reduce interference of the operating frequency of the charging adapter on the communication frequency, and the frequency conversion instruction is used to instruct the charging adapter to use a frequency converter, and convert the operating frequency according to the preset variation value.
For example, steps S206 and S207 may include:
if the terminal determines that the target frequency interval is smaller than the preset interval threshold, it may be considered that the harmonic of the operating frequency of the charging adapter may cause interference to the communication frequency of the terminal. In this case, the terminal may send a frequency conversion instruction to the charging adapter, where the frequency conversion instruction carries a preset variation value, and the frequency conversion instruction is used to instruct the charging adapter to use its frequency conversion device and convert the operating frequency according to the preset variation value, so as to reduce interference of the operating frequency of the charging adapter on the communication frequency.
It can be understood that after the charging adapter converts the operating frequency of the charging adapter, the harmonic frequency of the charging adapter changes greatly due to the change of the operating frequency of the charging adapter, so that the interference of the operating frequency of the charging adapter on the communication frequency can be effectively reduced.
In an embodiment, the frequency conversion instruction sent by the terminal to the charging adapter may carry a preset variation amplitude, and is used to instruct the charging adapter to use the frequency converter, so as to reduce or increase the operating frequency of the charging adapter according to the preset variation amplitude.
In step S208, if it is determined that the target frequency interval is greater than or equal to the preset interval threshold, the terminal determines that the harmonic of the operating frequency does not interfere with the communication frequency.
In step S209, the terminal performs other operations.
For example, steps S208 and S209 may include:
if the terminal determines that the target frequency interval is not less than the preset interval threshold, it may be considered that the harmonic of the operating frequency of the charging adapter does not cause interference to the communication frequency of the terminal. In this case, the terminal may perform other operations.
In one embodiment, if the value of the communication frequency acquired by the terminal is large (e.g., not lower than 800MHz), the terminal may calculate a frequency interval between the communication frequency and an operating frequency of the charging adapter, and determine that there is interference between the communication frequency and the operating frequency if it is detected that the frequency interval is smaller than a preset interval threshold. The terminal may then send a frequency conversion command to the connected charging adapter, the command instructing the charging adapter to convert its operating frequency.
Referring to fig. 3, fig. 3 is a schematic view of a scenario of a radio frequency interference processing method according to an embodiment of the present invention.
For example, in the case of performing radio frequency communication and charging simultaneously, the terminal may first acquire a communication frequency currently used by the terminal for data reception. For example, as shown in fig. 3, the communication frequency currently used by the terminal for data reception (downstream communication frequency) is 869.2 MHz.
Thereafter, the terminal may obtain an operating frequency of a charging adapter connected thereto, which may include a frequency conversion device. For example, the operating frequency of the terminal acquiring the charging adapter is 108 MHz.
The terminal may then determine a predetermined order of the operating frequency for the higher harmonic frequencies and calculate the frequency separation of each higher harmonic frequency from the communication frequency. For example, the preset number of times is 2 to 10 times. Then the 2 nd harmonic frequency to the 10 th harmonic frequency of the operating frequency are: 216MHz, 324MHz, 432MHz, 540MHz, 648MHz, 756MHz, 864MHz, 972MHz, 1080 MHz.
The terminal may then calculate the frequency separation of each higher harmonic frequency from the communication frequency. For example, the downlink communication frequency of the terminal is 869.2 MHz. Then, the frequency intervals between the 2 nd harmonic frequency to 10 th harmonic frequency of the operating frequency of the charging adapter and the downstream communication frequency are: 761.2MHz, 545.2MHz, 437.2MHz, 329.2MHz, 221.2MHz, 113.2MHz, 5.2MHz, 102.8MHz, 210.8 MHz.
After calculating the frequency interval between each of the higher harmonic frequencies and the communication frequency of the terminal, the terminal may determine the frequency interval with the smallest value as the target frequency interval. For example, the smallest value in the frequency interval between the 2 nd harmonic frequency to the 10 th harmonic frequency of the operating frequency of the charging adapter and the downstream communication frequency is 5.2MHz (corresponding to the 5 th harmonic frequency).
After determining the target frequency interval, the terminal may determine whether the target frequency interval is smaller than a preset interval threshold. For example, the preset interval threshold is 30 MHz. Then, the terminal determines that the target frequency interval is smaller than a preset interval threshold. In this case, it is considered that the harmonic of the operating frequency of the charging adapter causes interference with the communication frequency of the terminal. At this time, the terminal may send a frequency conversion instruction to the charging adapter, where the frequency conversion instruction carries a preset change amplitude, and the frequency conversion instruction is used to instruct the charging adapter to use its frequency conversion device, and convert the operating frequency according to the preset change amplitude.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a radio frequency interference processing apparatus according to an embodiment of the present invention. The radio frequency interference processing apparatus 300 may include: a first obtaining module 301, a second obtaining module 302, a judging module 303, and a sending module 304.
The first obtaining module 301 is configured to obtain a communication frequency of a terminal when the terminal performs communication and charging.
For example, when detecting that the terminal performs radio frequency communication and charging simultaneously, the first obtaining module 301 may first obtain a current communication frequency of the terminal.
A second obtaining module 302, configured to obtain an operating frequency of a charging adapter connected to the terminal, where the charging adapter includes a frequency converter.
For example, after the first obtaining module 301 obtains the communication frequency of the terminal, the second obtaining module 302 may obtain an operating frequency of a charging adapter connected thereto, and the charging adapter may include a frequency conversion device.
The determining module 303 is configured to determine whether there is interference between the operating frequency and the communication frequency.
A sending module 304, configured to send a frequency conversion instruction to the charging adapter to reduce interference of the operating frequency of the charging adapter to the communication frequency if there is interference between the operating frequency and the communication frequency, where the frequency conversion instruction is used to instruct the charging adapter to convert the operating frequency by using the frequency converter.
For example, after the first obtaining module 301 obtains the communication frequency of the terminal and the second obtaining module 302 obtains the operating frequency of the charging adapter connected to the terminal, the determining module 303 may determine whether interference is generated between the operating frequency and the communication frequency.
If the determining module 303 determines that no interference is generated between the operating frequency and the communication frequency, the terminal may continue to perform other operations.
If the determining module 303 determines that interference is generated between the operating frequency and the communication frequency, the sending module 304 may send a frequency conversion instruction to the charging adapter, where the frequency conversion instruction is used to instruct the charging adapter to convert the operating frequency by using its frequency converter device, so as to reduce the interference of the operating frequency of the charging adapter to the communication frequency.
It should be noted that the operating frequency of the charging adapter of most terminals is 108MHz or higher, and the operating frequency (or its harmonic frequency) is liable to cause interference to the communication frequency of the low frequency band (for example, the communication frequency of the 700-900 MHz frequency band). According to the embodiment of the invention, when the working frequency of the charging adapter is judged to generate interference on the communication frequency of the terminal, the terminal sends the frequency conversion instruction to the charging adapter, and the instruction is used for instructing the charging adapter to convert the working frequency of the charging adapter, so that the interference of the working frequency of the charging adapter on the communication frequency is reduced. After the charging adapter converts the working frequency of the charging adapter, the working frequency of the charging adapter and the harmonic frequency of the charging adapter are changed, so that the interference of the working frequency of the charging adapter to the communication frequency can be effectively reduced.
In one embodiment, the determining module 303 may be configured to:
and judging whether the higher harmonic waves of the working frequency and the communication frequency have interference or not.
For example, after the second obtaining module 302 obtains the operating frequency of the charging adapter connected to the terminal, the determining module 303 may determine whether a harmonic of the operating frequency may interfere with the communication frequency of the terminal.
In one embodiment, the determining module 303 may be configured to:
determining each higher harmonic frequency of the working frequency, and calculating the frequency interval between each higher harmonic frequency and the communication frequency;
determining the frequency interval with the minimum value as a target frequency interval, and judging whether the target frequency interval is smaller than a preset interval threshold value;
if the target frequency interval is smaller than a preset interval threshold value, determining that the harmonic wave of the working frequency has interference with the communication frequency;
and if the target frequency interval is judged to be larger than or equal to a preset interval threshold value, determining that the harmonic wave of the working frequency does not interfere with the communication frequency.
For example, after the second obtaining module 302 obtains the operating frequency of the charging adapter, the determining module 303 may determine harmonic frequencies of a preset number of times of the operating frequency, and calculate a frequency interval between each harmonic frequency and the communication frequency of the terminal.
After calculating the frequency interval between each harmonic frequency and the communication frequency of the terminal, the determining module 303 may determine the frequency interval with the smallest value as the target frequency interval.
For example, the minimum value of the frequency intervals between the harmonic frequencies of the operating frequency of the charging adapter and the downstream communication frequency is 5.2 MHz. Then the decision module 303 may determine the frequency interval with the smallest value as the target frequency interval, which is 5.2 MHz.
Then, the determining module 303 may determine whether the target frequency interval is smaller than a preset interval threshold.
If the target frequency interval is smaller than the preset interval threshold, the determining module 303 may determine that the harmonic of the operating frequency interferes with the communication frequency of the terminal.
If the target frequency interval is greater than or equal to the preset interval threshold, the determining module 303 may determine that the harmonic of the working frequency does not interfere with the communication frequency.
In one embodiment, the sending module 304 may be configured to:
and sending a frequency conversion instruction to the charging adapter, wherein the frequency conversion instruction carries a preset change value, and the frequency conversion instruction is used for indicating the charging adapter to use the frequency conversion device and converting the working frequency according to the preset change value.
For example, the frequency conversion instruction sent by the sending module 304 to the charging adapter may carry a preset variation amplitude, and is used to instruct the charging adapter to use the frequency converter, and reduce or increase the operating frequency of the charging adapter according to the preset variation amplitude.
In one embodiment, the determining module 303 may be configured to:
and determining the higher harmonic frequency of the preset order of the working frequency, wherein the numerical value of the preset order is less than 50, and calculating the frequency interval between each higher harmonic frequency and the communication frequency.
For example, after the second acquiring module 302 acquires the operating frequency of the charging adapter, the judging module 303 may determine a harmonic frequency of a preset order of the operating frequency, and calculate a frequency interval between each harmonic frequency and the communication frequency of the terminal.
In one embodiment, the predetermined order number is less than 50. For example, the number of the preset order includes 2 to 10, i.e., the terminal determines the harmonic frequencies of 2 th harmonic to 10 th harmonic.
For example, the second obtaining module 302 obtains that the operating frequency of the charging adapter connected to the terminal is 108MHz, and the preset order is 2 to 10. Then the decision module 303 may determine that the 2 nd harmonic frequency to the 10 th harmonic frequency of the operating frequency are: 216MHz, 324MHz, 432MHz, 540MHz, 648MHz, 756MHz, 864MHz, 972MHz, 1080 MHz.
The determination module 303 may then calculate a frequency separation of each harmonic frequency from the communication frequency. For example, the downlink communication frequency of the terminal is 869.2 MHz. Then, the determining module 303 calculates frequency intervals between the frequency of the harmonic of 2 th order to the frequency of the harmonic of 10 th order of the operating frequency of the charging adapter and the downlink communication frequency as follows: 761.2MHz, 545.2MHz, 437.2MHz, 329.2MHz, 221.2MHz, 113.2MHz, 5.2MHz, 102.8MHz, 210.8 MHz.
