DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.
The term "module" as used herein may be considered a software object executing on the computing system. The various components, modules, engines, and services described herein may be viewed as objects implemented on the computing system. The apparatus and method described herein are preferably implemented in software, but may also be implemented in hardware, and are within the scope of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. The electronic device may be a smart phone, a tablet computer, a Personal Digital Assistant (PDA), or the like having a wireless communication function.
The electronic device comprises a plurality of communication modules (such as a first communication module 21 and a second communication module 22), a communication detection module 23 and a processor 10, wherein each communication module and the communication detection module 23 are electrically connected with the processor 10.
The first communication module 21 and the second communication module 22 are configured to receive or transmit different radio frequency signals, so that the electronic device 100 can implement a plurality of different communication functions. For example, when the first communication module is a cellular communication module, the electronic device may receive or transmit a cellular signal through an antenna corresponding to the cellular communication module, so as to implement a cellular communication function of the electronic device. When the second communication module is a Wireless Fidelity communication module, the electronic device may receive or transmit a Wireless Fidelity (Wi-Fi) signal through an antenna corresponding to the Wireless Fidelity communication module, so as to implement a Wireless Fidelity communication function of the electronic device.
The communication detection module 23 is configured to detect a working state of each communication module, where the working state includes a working mode and a non-working mode, and when a certain communication module is in the working mode, it may be determined that a communication function of the communication module in the current electronic device is in an on state. Or when a certain communication module is in the non-operating mode, it may be determined that the communication function of the communication module is not turned on by the current electronic device, that is, the communication function of the communication module belongs to the off state.
For example, when the communication detection module 23 detects that the first communication module 21 is in the working mode, indicating that the communication service corresponding to the first communication module 21 in the current electronic device is in an on state, the electronic device 100 may perform the first communication service through the first communication module 21. Or, when the communication detection module 23 detects that the first communication module 21 is in the non-operating mode, it indicates that the communication service corresponding to the first communication module 21 in the electronic device 100 is in the closed state, and the electronic device 100 cannot perform the first communication service through the first communication module 21.
Further, when the communication detection module 23 detects that the communication module is in the working mode, the communication detection module 23 may further obtain a plurality of communication parameters of each communication module in the working mode, for example, parameters such as an antenna, transmission power, and a working frequency band used for transmitting a signal by the communication module in the working mode may be obtained, and the obtained working state and the obtained communication parameters are sent to the processor, so that the processor may adjust the transmission power of the communication module according to the working state and the communication parameters.
Meanwhile, please refer to fig. 2, fig. 2 is a second structural schematic diagram of the electronic device according to the embodiment of the present application. The electronic device 100 shown in fig. 2 is different from the electronic device 100 shown in fig. 1 in that the plurality of communication modules of the electronic device 100 shown in fig. 2 specifically include a cellular communication module 24, a wifi communication module 25 and a long-distance wireless communication module 26, and each communication module is electrically connected to at least two antennas 27.
Among the plurality of antennas 27 corresponding to each communication module, the plurality of antennas 27 may be all used for receiving and transmitting radio frequency signals in different frequency bands. Alternatively, there may be a portion of the plurality of antennas 27 for transmitting only radio frequency signals, or a portion of the plurality of antennas 27 for receiving only radio frequency signals.
When the cellular communication module 24 is in the working mode, the electronic device 100 can receive or transmit cellular signals through the antenna 27 corresponding to the cellular communication module 24, so as to implement the cellular communication function of the electronic device.
When the wifi communication module 25 is in the working mode, the electronic device 100 may receive or transmit a Wireless Fidelity (Wi-Fi) signal through the antenna 27 corresponding to the wifi communication module 25, so as to implement the wifi communication function of the electronic device 100.
In addition, the long-distance wireless communication module 26 is designed based on a Low Power Wide Area internet of things (LPWAN) technology, and is a communication module for connecting people and objects, and connecting objects and objects with a large number of wireless communication technologies at long distance and Low Power consumption. The long-range wireless communication module 26 may also be referred to as an LPWAN communication module.
The radio frequency transceiver of the Long-Range wireless communication module 26 may use spread spectrum communication technology or low bandwidth communication technology or a combination of the two, for example, the Long-Range wireless communication module 26 may support at least one of Long Range (Lora), SigFox, Weightless, Random Phase Multiple Access (RPMA), Qowisio, N-Wave, telens, DART, NB-IoT, and may also support medium and Long Range private communication protocols. Based on the working frequency band and the communication physical layer characteristics of LPWAN, the long-distance wireless communication module 26 can transmit data signals within hundreds of meters to several kilometers.
Therefore, when the long-distance wireless communication module 26 is in the operating mode, the electronic device 100 can receive or transmit LPWAN wireless signals through the antenna 27 corresponding to the long-distance wireless communication module 26, so as to implement the long-distance wireless communication function of the electronic device 100.
Further, the communication detection module 23 may specifically acquire a plurality of communication parameters, such as a transmitting antenna used for transmitting a signal, a receiving antenna used for receiving a signal, and a transmitting power operation corresponding to each transmitting antenna in each communication module when each communication module is in the operating mode.
Referring to fig. 3, fig. 3 is a first flowchart of a method for adjusting transmit power according to an embodiment of the present disclosure. The method for adjusting the transmission power may be applied to the electronic device 100 shown in fig. 1 and 2, wherein the electronic device includes a plurality of communication modules. Specifically, the method for adjusting the transmission power may include the following steps:
101, respectively obtaining the working state corresponding to each communication module.
The electronic device may obtain a working state corresponding to each communication module detected by the communication detection module, where the working state includes a working mode and a non-working mode.
And 102, determining target communication modules with working states as working modes, and calculating the total SAR value of the electronic equipment according to the SAR value corresponding to each target communication module.
Wherein, the communication module whose working state is the working mode can be determined as the target communication module. It can be understood that when a certain communication module is in the working mode, it may be determined that the communication function of the communication module in the current electronic device is in the on state, and when a certain communication module is in the non-working mode, it may be determined that the communication function of the communication module is not turned on by the current electronic device, that is, the communication function of the communication module belongs to the off state.
For example, when the communication detection module detects that the cellular communication module is in the operating mode, it indicates that the cellular communication service corresponding to the cellular communication module in the electronic device is in an on state, that is, the cellular communication function in the electronic device is in an on state, and the electronic device may perform cellular communication through the cellular communication module. Or, when the communication detection module detects that the cellular communication module is in the non-operating mode, it indicates that the cellular communication service corresponding to the cellular communication module of the current electronic device is in the closed state, and the electronic device cannot perform the cellular communication service through the cellular communication module.
Therefore, only when the communication module is in the working mode, the antenna corresponding to the communication module can transmit or receive the radio frequency signal, and at the moment, the electromagnetic wave generated by the antenna corresponding to the communication module through radiation can generate radiation influence on a user.
Therefore, when the electronic device exists and the communication module is in the working mode, whether the Specific Absorption Rate (SAR) of the electronic device is within the range of the safety standard needs to be predicted. The SAR parameter refers to electromagnetic radiation energy absorbed by a substance with unit mass in unit time, and is an important parameter for measuring the influence of radiation of an intelligent terminal with an antenna such as a mobile phone on a human body. Wherein the lower the SAR value, the less the amount of radiation absorbed by the body.
If the SAR total value of the current electronic equipment exceeds the safety standard range, namely the SAR parameter of the electronic equipment exceeds the standard, the transmission power of the communication module in the working mode needs to be adjusted so as to reduce the SAR total value of the electronic equipment.
Specifically, after the target communication modules in the working mode of the electronic device are determined to exist, the SAR value corresponding to each target communication module working at the maximum transmission power can be obtained, and the SAR total value of the electronic device is determined according to the SAR value corresponding to the maximum transmission power of each communication module.
It will be appreciated that the actual transmit power of each communication module is no greater than the maximum transmit power. Therefore, the SAR value corresponding to each target communication module acquired by the method is the SAR maximum value corresponding to the communication module, so that the total SAR value of the current electronic equipment predicted according to the SAR maximum value of each target communication module is also the SAR maximum value of the current electronic equipment.
The SAR value (namely the maximum SAR value) corresponding to the communication module is used as the SAR value corresponding to the communication module when the maximum transmitting power works, so that the SAR value corresponding to each target communication module can be quickly obtained, the detection or the calculation of the current SAR value is not needed, the processing time of the communication module for obtaining the SAR value can be saved, and the processing efficiency of the SAR total value of the electronic equipment is improved.
It can be understood that, if the total SAR value (maximum SAR value) of the current electronic device is within the safety standard range of the SAR, the real SAR value of the electronic device will also be within the safety standard range of the SAR. At this time, after the maximum value of the SAR of each target communication module is obtained, whether the total value of the SAR of the current electronic equipment exceeds the standard or not can be rapidly determined.
Or, when the maximum SAR value of the current electronic device is not within the range of the safety standard of the SAR, that is, the current electronic device may have a problem that the total SAR value exceeds the standard, at this time, the transmission power of the communication module in the working mode needs to be adjusted according to the actual situation of the electronic device, so as to reduce the total SAR value of the electronic device.
In some embodiments, the calculating the total SAR value of the electronic device according to the SAR value corresponding to each target communication module may include:
acquiring a target antenna used for transmitting signals in each target communication module;
respectively acquiring an SAR value corresponding to each target antenna in each target communication module according to a preset mapping table;
and adding the SAR values corresponding to each target antenna in each target communication module to obtain a first SAR value of each target communication module.
And calculating to obtain the total SAR value according to the first SAR values corresponding to the target communication modules.
In some embodiments, calculating the SAR total value according to the first SAR values corresponding to the plurality of target communication modules may include:
acquiring a communication coefficient corresponding to each target communication module according to a target antenna corresponding to each target communication module; multiplying the first SAR value of each communication module by the corresponding communication coefficient to obtain a second SAR value corresponding to each communication module; adding a plurality of second SAR values to obtain the SAR total value.
The communication coefficient of each communication module corresponds to the antenna in the communication module one by one, and after the target antenna of the communication module is determined, the communication coefficient corresponding to the target antenna can be used as the communication coefficient of the corresponding communication module. If there are a plurality of target antennas in the target communication module, the communication coefficient having the largest value may be selected from the plurality of communication coefficients corresponding to the plurality of target antennas as the communication coefficient of the target communication module.
It can be understood that, since each communication module can be connected to a plurality of antennas, when the antennas in the target communication module in the operating mode are different, the corresponding SAR values are different. Therefore, the target antenna used for transmitting signals in each target communication module can be further acquired after the target communication module in the working mode is detected. And determining the SAR value corresponding to each target antenna from a preset mapping table according to the target antenna and the target communication module. The preset mapping table stores SAR values which can be generated when each antenna of each communication module works at the maximum transmitting power.
Therefore, the SAR value corresponding to each target antenna determined in the present application is the maximum SAR value that can be generated by the target antenna at the maximum transmission power, and then the SAR values of each target antenna in each target communication module are added to obtain the maximum SAR value (i.e., the first SAR value) of each target communication module in the current working state of the target antenna.
Further, the maximum SAR values of each target communication module are added to obtain the maximum SAR value (i.e., the total SAR value) of the current electronic device when the plurality of target antennas are in operation.
Therefore, the target antenna used for transmitting signals in each target communication module is obtained, and the SAR value of each communication module obtained according to the target antenna is used for enabling the SAR value of each communication module to be closer to the SAR value under the real condition, so that the SAR total value of the electronic equipment obtained through prediction is closer to the SAR total value of the electronic equipment under the real condition, and the result of determining whether the SAR value of the current electronic equipment exceeds the standard according to the SAR total value of the electronic equipment is more accurate.
In some embodiments, the calculating a total SAR value of the electronic device according to the SAR value corresponding to each target communication module may further include:
acquiring a working frequency band corresponding to each target communication module;
and respectively acquiring the SAR value corresponding to the working frequency band of each target communication module according to a preset mapping table, and taking the SAR value as the SAR value of the corresponding target communication module.
And calculating the SAR total value according to the SAR values corresponding to the target communication modules.
It can be understood that, when the antenna corresponding to each communication module operates, radio frequency signals of a plurality of operating frequency bands can be generated, and for the same antenna, the operating frequency bands are different, and the generated SAR values are also different.
Therefore, after the target communication module in the working mode is detected, the corresponding working frequency band in each target communication module can be further obtained, the working frequency bands can be one or more, for example, when the target communication module has a plurality of antennas to work, the corresponding working frequency bands can also be multiple. And respectively acquiring the SAR value corresponding to the working frequency band of each target communication module according to a preset mapping table, and taking the SAR value as the SAR value of the corresponding target communication module. The preset mapping table stores SAR values which can be generated when each communication module works in a working frequency band at the maximum transmission power. That is, the SAR value corresponding to a certain working frequency band in a certain communication module is the maximum SAR value when the communication module works in the certain working frequency band.
Further, the maximum SAR values of each target communication module are added to obtain the maximum SAR value (i.e., the total SAR value) of the current electronic device when the plurality of target antennas are in operation.
Therefore, the working frequency band of each target communication module is obtained, the SAR value of each communication module is obtained according to the working frequency band, the SAR value of each communication module obtained through calculation can be closer to the SAR value under the real condition, the SAR total value of the electronic equipment obtained through prediction is closer to the SAR total value of the electronic equipment under the real condition, and the result that whether the SAR value of the current electronic equipment exceeds the standard or not according to the SAR total value of the electronic equipment is determined more accurately.
And 103, when the SAR total value is larger than the preset SAR value, determining the target transmitting power corresponding to each target communication module.
When the total SAR value of the electronic device is greater than the preset SAR value, it indicates that the maximum SAR value of the current electronic device is not within the safety standard range of the SAR, that is, the current electronic device may have a problem that the total SAR value exceeds the standard, and at this time, the target transmission power corresponding to each target communication module may be determined according to the actual communication condition of the current electronic device, for example, according to the communication parameters corresponding to each target communication module acquired by the communication detection module, where each target transmission power is less than the maximum transmission power of the corresponding target communication module.
In addition, it is also required to ensure that when each target communication module operates at the corresponding target transmission power, the total SAR value of the electronic device is smaller than the preset SAR value, so that when each target communication module operates at the corresponding target transmission power, the total SAR value of the electronic device does not exceed the standard.
104, determining the target communication module to be adjusted according to the current transmitting power of each target communication module and the corresponding target transmitting power, and adjusting the transmitting power of the target communication module to be adjusted.
According to the actual communication condition of the current electronic device, for example, the obtained communication parameters corresponding to each target communication module, such as the current transmission power of each target communication module, whether to adjust the transmission power of the target communication module is determined according to the current transmission power and the corresponding target transmission power, so as to determine the target communication module to be adjusted, and adjust the transmission power of the target communication module to be adjusted, so that the total SAR value of the electronic device after the transmission power adjustment is smaller than the preset SAR value.
As can be seen from the above, the method for adjusting transmission power provided in the embodiment of the present application is applied to an electronic device including a plurality of communication modules, and can respectively obtain a working state corresponding to each communication module, where the working state includes a working mode and a non-working mode; determining target communication modules with working states as working modes, and calculating the total SAR value of the electronic equipment according to the SAR value corresponding to each target communication module; when the SAR total value is larger than a preset SAR value, determining target transmitting power corresponding to each target communication module; and determining a target communication module to be adjusted according to the current transmitting power of each target communication module and the corresponding target transmitting power, and adjusting the transmitting power of the target communication module to be adjusted. The method and the device can intelligently adjust the transmitting power of each communication module according to the working states of different communication modules, so that the SAR total value of the electronic equipment cannot exceed the standard even if a plurality of communication modules are in the working mode at the same time.
In some embodiments, please refer to fig. 4, where fig. 4 is a second flowchart of a method for adjusting transmit power according to an embodiment of the present disclosure. The method for adjusting the transmission power may be applied to the electronic device 100 shown in fig. 1 and fig. 2, wherein the electronic device 100 includes a plurality of communication modules, and each communication module is electrically connected to a plurality of antennas. Specifically, the method for adjusting the transmission power may include the following steps:
201, respectively obtaining the working state corresponding to each communication module.
The electronic device may obtain a working state corresponding to each communication module detected by the communication detection module, where the working state includes a working mode and a non-working mode.
And 202, determining the target communication modules with the working states as working modes, and acquiring a target antenna used for transmitting signals in each target communication module.
Because each communication module can be connected with a plurality of antennas, when the antennas in the working mode in the target communication module are different, the corresponding SAR values are different. Therefore, after the target communication modules in the working mode are detected, the target antenna used for transmitting signals in each target communication module is further acquired, so that the SAR value of the corresponding target communication module can be determined according to the SAR value of the target antenna.
And 203, determining the working frequency band corresponding to each target antenna.
It can be understood that, when the antenna corresponding to each communication module operates, radio frequency signals of a plurality of operating frequency bands can be generated, and for the same antenna, the operating frequency bands are different, and the generated SAR values are also different.
Therefore, after the target communication module in the working mode is detected, the corresponding working frequency band in each target communication module can be further obtained, the working frequency bands can be one or more, for example, when the target communication module has a plurality of antennas to work, the corresponding working frequency bands can also be multiple.
And 204, determining the SAR value matched with the working frequency band corresponding to each target antenna from a preset mapping table to serve as the SAR value corresponding to each target antenna.
The preset mapping table stores SAR values corresponding to each antenna when the antenna works in different working frequency bands, and the SAR values are SAR values which can be generated when the corresponding antenna works in a certain working frequency band at the maximum transmitting power. That is, the SAR value is the maximum SAR value that the corresponding antenna can generate in the operating band.
205, adding the SAR values corresponding to each target antenna in each target communication module to obtain a first SAR value of each target communication module.
And adding the SAR values corresponding to the target antennas under each target communication module to obtain a first SAR value corresponding to each target communication module.
Since the SAR value corresponding to each target antenna determined in step 204 is the maximum SAR value that can be generated when the target antenna operates at the maximum transmission power, the first SAR value corresponding to the target communication module calculated from the SAR values corresponding to the plurality of target antennas is also the maximum SAR value of the target communication module in the current scenario.
And 206, acquiring the communication coefficient of the corresponding target communication module according to each target antenna.
The communication coefficient of each communication module corresponds to the antenna in the communication module one by one, and after the target antenna of the communication module is determined, the communication coefficient corresponding to the target antenna can be used as the communication coefficient of the corresponding communication module. If there are a plurality of target antennas in the target communication module, the communication coefficient having the largest value may be selected from the plurality of communication coefficients corresponding to the plurality of target antennas as the communication coefficient of the target communication module.
In some embodiments, the communication coefficient corresponding to each antenna may be determined according to the SAR value of the antenna in the preset mapping table. When the SAR value corresponding to the antenna is maximum, the communication coefficient corresponding to the antenna is larger.
And 207, multiplying the first SAR value of each target communication module by the corresponding communication coefficient to obtain a second SAR value corresponding to each target communication module.
And 208, adding the plurality of second SAR values to obtain the SAR total value of the electronic equipment.
And 209, when the SAR total value is larger than the preset SAR value, acquiring corresponding target rollback power according to the SAR value corresponding to each target communication module.
