Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1, a flowchart illustrating steps of a method for reducing an SAR value according to a first embodiment of the present invention is shown.
The method for reducing the SAR value provided by the embodiment of the invention comprises the following steps:
step 101: the mobile terminal obtains the number of transmitters in the current working state and the transmitting power of the transmitters in the working state.
The SAR value, i.e. the specific absorption rate, is averaged over any 6 minute epoch, per kilogram of electromagnetic radiation energy (watts) absorbed by the human tissue. Taking the mobile phone radiation as an example, SAR refers to the rate at which radiation is absorbed by the soft tissues of the head, the lower the SAR value, the less the amount of radiation absorbed by the brain.
Under different working modes of the mobile terminal, the number of the transmitters in working states is different. Such as a mobile terminal integrated with bluetooth, Wi-Fi, high-speed data network, NFC (Near Field Communication). The number of transmitters in operation is 1 or 2 in the data transmission mode, and the number of transmitters in operation is 3 or 4 in the mode of using the high-speed data network while answering a call.
Step 102: the mobile terminal adjusts the position of each transmitter in the working state according to the number of the transmitters in the working state at present, or adjusts the transmitting power of each transmitter in the working state, so as to reduce the SAR value of the mobile terminal.
When a plurality of transmitters are in working condition, the heat effect generated by human tissue may be superposed due to the radio frequency exposure generated by each transmitter, and the tolerance of human cell tissue to radio frequency energy has a certain limit value.
When the number of the transmitters in the working state is multiple, the SAR value of the transmitter is reduced by adjusting the position of each transmitter in the working state or adjusting the transmitting power of each transmitter in the working state.
For example: when the number of the transmitters in the working state is 2, the positions of the first transmitter and the second transmitter are adjusted to reduce the radio frequency superposition of the first transmitter and the second transmitter, so that the SAR value of the transmitters is reduced.
When more than two transmitters are in operation, the transmission power of each transmitter is adjusted to reduce the SAR value of the transmitter.
In the embodiment of the invention, the number of transmitters in the working state of the current mobile terminal and the transmission power of each transmitter in the working state are detected; the position of each transmitter in the working state is adjusted according to the number of the transmitters, or the transmitting power of each transmitter in the working state is adjusted to reduce the SAR value of the mobile terminal, so that the maximum SAR value can be furthest away from the two transmitters under the condition that a plurality of transmitters exist, the superposition effect generated when the two transmitters transmit simultaneously is weakened, in addition, under the condition that the plurality of transmitters transmit simultaneously, the transmitting power of each transmitter is reduced, the superposition effect generated by the simultaneous transmission is weakened, the potential risk to the safety of a human body is reduced, and the communication quality is ensured.
Example two
Referring to fig. 2, a flowchart illustrating steps of a method for reducing an SAR value according to a second embodiment of the present invention is shown.
The method for reducing the SAR value provided by the embodiment of the invention comprises the following steps:
step 201: the mobile terminal obtains the number of transmitters in the current working state and the transmitting power of the transmitters in the working state.
Under different working modes of the mobile terminal, the number of the transmitters in working states is different. Such as a mobile terminal integrated with bluetooth, Wi-Fi, high-speed data network, NFC (Near Field Communication). The number of transmitters in operation is 1 or two in the data transmission mode, and the number of transmitters in operation is 3 or 4 in the mode of using the high-speed data network while answering a call.
Step 202: when the number of the transmitters in the working state is 2, the mobile terminal diagonally arranges the first transmitter and the second transmitter.
For example: the first transmitter is arranged at the upper left corner of the mobile terminal, the second transmitter is arranged at the lower right corner of the mobile terminal, or the first transmitter is arranged at the upper right corner of the mobile terminal, and the second transmitter is arranged at the lower left corner of the mobile terminal.
Step 203: the mobile terminal adjusts the transmission power of the first transmitter and the second transmitter to the highest transmission power.
As shown in fig. 3, when there are multiple transmitters, the SAR values of the first transmitter and the second transmitter are the highest, the first transmitter and the second transmitter are placed diagonally, assuming that the SAR value generated by the transmitter 1 is SAR1, the SAR value generated by the second transmitter is SAR2, and the distance between the two transmitters is Ri, which is the farthest, the calculated value is small according to the formula (SAR1+ SAR2) of FCC (Federal Communications Commission) so as to reduce the superposition effect of SAR of the two transmitters to the maximum extent and reduce the potential risk to human body safety.
In the embodiment of the invention, the number of transmitters in the working state of the current mobile terminal and the transmission power of each transmitter in the working state are detected; when the transmitters in the working state are the first transmitter and the second transmitter, the first transmitter and the second transmitter are arranged diagonally, the transmitting power of the first transmitter and the transmitting power of the second transmitter are adjusted to be the highest transmitting power, the transmitters in the working state are arranged diagonally, the two transmitters with the largest SAR value can be furthest away, the superposition effect generated when the two transmitters transmit simultaneously is weakened, the potential risk of human body safety is reduced, and the communication quality is ensured.
EXAMPLE III
Referring to fig. 4, a flowchart illustrating steps of a method for reducing an SAR value according to a third embodiment of the present invention is shown.
The method for reducing the SAR value provided by the embodiment of the invention comprises the following steps:
step 301: the mobile terminal obtains the number of transmitters in the current working state and the transmitting power of the transmitters in the working state.
Under different working modes of the mobile terminal, the number of the transmitters in working states is different. Such as a mobile terminal integrated with bluetooth, Wi-Fi, high-speed data network, NFC (Near Field Communication). The number of transmitters in operation is 1 or two in the data transmission mode, and the number of transmitters in operation is 3 or 4 in the mode of using the high-speed data network while answering a call.
Step 302: when the number of the transmitters in the working state is 2, and the first transmitter and the second transmitter are diagonally arranged, the mobile terminal adjusts the transmission power of the first transmitter and the second transmitter to a first preset transmission power.
And when the first transmitter and the second transmitter are detected to be arranged diagonally, adjusting the transmission power of the first transmitter and the second transmitter to be a first preset transmission power.
It should be noted that, when there is one transmitter in the operating state, the transmission power of the transmitter is adjusted to the maximum transmission power, and the first preset transmission power is lower than the maximum transmission power.
When the number of the transmitters in the working state is 2, and each first transmitter and each second transmitter are arranged in parallel, the transmitting power of the first transmitter and the transmitting power of the second transmitter are adjusted to be second preset transmitting power, wherein the second preset transmitting power is smaller than the first preset transmitting power.
When the number of the transmitters in the working state is 3, adjusting the transmission power of the first transmitter, the second transmitter and the third transmitter to a third preset transmission power, wherein the third preset transmission power is smaller than the second preset transmission power.
Besides the method for reducing the SAR value, the method can also be used for detecting the condition of simultaneous transmission through software under the condition that a plurality of transmitting antennas transmit simultaneously, and calling different radio frequency parameters through different combinations, so that the superposition effect generated by the simultaneous transmission is weakened, the potential risk to the safety of a human body is reduced, in addition, under the condition that a plurality of transmitters work simultaneously, the transmitting power is reduced, meanwhile, the mutual interference among the transmitters is also reduced, and the performance of electromagnetic compatibility is improved.
