Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments obtained by a person skilled in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
At present, when a user uses a mobile terminal, the mobile terminal may reduce radiation of radio frequency signals to a human body by reducing radio frequency power, generally, a SAR (Specific Absorption Rate) reduction mechanism is used, but a script for the SAR reduction mechanism is not perfect in detection at present, for example, a gravity accelerator is used only for detection, so that the mobile terminal may be handled by the user, but under the condition of no movement, the SAR reduction mechanism is not started, and in order to implement the mechanism, many SAR sensors need to be added on the mobile terminal, and meanwhile, certain difficulty and cost are added in circuit design.
Based on this, the method for controlling antenna power of the mobile terminal and the mobile terminal provided in the embodiments of the present application can alleviate the above problem.
To facilitate understanding of the present embodiment, a detailed description is first given of a method for controlling antenna power of a mobile terminal disclosed in the embodiments of the present application.
Specifically, the method for controlling the antenna power of the mobile terminal provided in the embodiment of the present application may be applied to a mobile terminal, where the mobile terminal includes a mobile terminal having an antenna structure, such as a smart phone, a tablet computer, and a palmtop computer, so as to execute the method for controlling the antenna power of the mobile terminal provided in the embodiment of the present application. Specifically, the flowchart of the method for controlling the antenna power of the mobile terminal shown in fig. 1 includes the following steps:
step S102, monitoring a receiver starting signal of the mobile terminal and a human body approach signal of a human body approaching the mobile terminal;
specifically, the monitoring process in step S102 is to monitor an earphone starting signal of the mobile terminal and a human body approach signal of a human body approaching the mobile terminal in a call state.
Step S104, determining whether to start the millimeter wave scanning function of the mobile terminal according to the monitoring result;
specifically, the millimeter wave scanning function of the mobile terminal is a directional scanning function of the millimeter wave antenna module, and whether an object is close to the mobile terminal can be distinguished through strength of a signal returned by scanning.
Taking the mobile terminal as an example of a smart phone, when the mobile terminal enters a call state, if a user picks up the smart phone and places the smart phone on the face to answer, the receiver is automatically turned on, at this time, the smart phone can monitor a receiver starting signal, if the user selects a hands-free function to call, the receiver is not turned on, and at this time, the mobile terminal cannot monitor the receiver starting signal.
Further, the human body proximity signal in the embodiment of the present application is generally detected by a proximity sensor on the mobile terminal, for example, an infrared sensor or the like, which monitors the human body proximity signal. In step S104, whether to start the millimeter wave scanning function of the mobile terminal is determined according to the monitoring result of the earphone starting signal and the human body proximity signal.
Specifically, in the embodiment of the application, if an earphone starting signal is monitored and a human body approaching signal is not monitored, the millimeter wave scanning function of the mobile terminal is determined to be started; alternatively, the first and second electrodes may be,
and if the earphone starting signal is not monitored and the human body approaching signal is not monitored, determining to start the millimeter wave scanning function of the mobile terminal.
Step S106, if the millimeter wave scanning function is determined to be started, acquiring echo signals scanned by the millimeter wave scanning function after the millimeter wave scanning function is started;
step S108, determining the approaching direction of the human body approaching the mobile terminal according to the echo signal;
step S110, adjusting the antenna power of the mobile terminal based on the approaching direction.
When in actual use, millimeter wave antenna module sets up the border position at mobile terminal usually, therefore, after opening millimeter wave scanning function, if there is the human body to be close to this mobile terminal then can determine the human body and be close to the direction that is close to mobile terminal through echo signal, and then make the mobile terminal adjust the antenna power of this method, for example, reduce or close the radio frequency power of the antenna that is close to the direction, or promote the radio frequency power etc. of the antenna of comparatively keeping away from the direction, in order to reduce the radiation to the human body under the circumstances of guaranteeing that mobile terminal normally talks, or guarantee that mobile terminal conversation signal can not receive the human body and influence.
Therefore, the method for controlling the antenna power of the mobile terminal provided by the embodiment of the application can monitor a receiver starting signal of the mobile terminal and a human body approach signal of a human body approaching the mobile terminal; determining whether to start a millimeter wave scanning function of the mobile terminal according to the monitoring result; if the millimeter wave scanning function is determined to be started, acquiring an echo signal scanned by the millimeter wave scanning function after the millimeter wave scanning function is started; determining the approaching direction of the human body approaching the mobile terminal according to the echo signal; and then adjust mobile terminal's antenna power based on this direction of approach, and millimeter wave scanning function is the function of mobile terminal's millimeter wave antenna usually, consequently, need not additionally to set up special sensor and go to survey human body and be close the signal, has reduced circuit design's the degree of difficulty, simultaneously, also helps satisfying mobile terminal to the requirement of miniaturized design development, has improved user's experience degree.
In practical use, the mobile terminal is provided with at least one millimeter wave antenna and at least one SAR sensor; the at least one millimeter wave antenna and the at least one SAR sensor are arranged at preset positions of a moving edge, and the echo signals are signals generated after the millimeter wave antenna scans a preset area; the human body approach signal is a signal generated when the SAR sensor senses that a human body approaches, and when the millimeter wave antenna is multiple, a millimeter wave antenna module can be formed.
For ease of understanding, fig. 2 shows a schematic structural diagram of a mobile terminal, as shown in fig. 2, and for ease of description, only an outline view of the mobile terminal, and positions of an antenna and a SAR sensor are shown in fig. 2.
Specifically, in order to ensure the communication function of the mobile terminal, the mobile terminal further includes a 2G/3G/4G antenna in addition to the millimeter wave antenna required in the embodiment of the present application, so as to meet the communication requirements of the mobile terminal in different frequency bands and different network environments. In fig. 2, ANT0 to ANT7 are 2G/3G/4G antennas, the shaded positions are millimeter wave antennas, and Sensor-1 and Sensor-2 in fig. 2 are SAR sensors.
It should be understood that, the mobile terminal in fig. 2 shows a schematic position diagram of one possible antenna and sensor, and in other embodiments, the number and the arrangement positions of the antennas and the sensors may also be set according to the actual use situation, which is not limited by the embodiment of the present application.
Further, the mobile terminal shown in fig. 2 uses the directional scanning function of the millimeter wave antenna module, so that the number of required SAR sensors can be reduced, which is helpful for the miniaturization development of the mobile terminal and also reduces the difficulty of circuit design.
Further, in the embodiment of the present application, when determining the approaching direction of the human body approaching the mobile terminal based on the echo signal, the determination is performed according to the intensity of the echo signal, and specifically, if the signal intensity of the echo signal is higher than a preset intensity threshold, the direction corresponding to the echo signal is determined as the approaching direction of the human body approaching the mobile terminal.
In actual use, the echo signal is usually a signal scanned by a millimeter wave scanning function after being reflected by a human body or an object thereof, and since the mobile terminal is provided with a plurality of millimeter wave antennas, in order to avoid misjudgment, the intensity threshold value is usually set, the echo signal scanned by the millimeter wave antennas is screened, and then the direction corresponding to the echo signal exceeding the intensity threshold value is determined as the approaching direction of the human body approaching the mobile terminal.
Further, for the determined approaching direction, when the antenna power of the mobile terminal is adjusted, the millimeter wave antenna corresponding to the approaching direction may be determined as the target millimeter wave antenna, and the frequency of the target millimeter wave antenna may be adjusted according to a preset frequency mode, for example, the frequency of the target millimeter wave antenna is reduced.
Specifically, the preset frequency mode generally refers to a radiation frequency corresponding to the target millimeter wave antenna, and taking the mobile terminal shown in fig. 2 as an example, if the millimeter wave antenna is set at a middle position between the top of the mobile terminal and the body edge of the mobile terminal, if it is determined that the millimeter wave antenna at the top is the target millimeter wave antenna according to the echo signal, the radiation frequency of the target millimeter wave antenna is set to the radiation frequency corresponding to the preset frequency mode; and if the millimeter wave antenna at the middle position of the edge of the body is the target millimeter wave antenna, setting the radiation frequency of the millimeter wave antenna at the middle position of the edge of the body as the radiation frequency corresponding to the preset frequency mode.
Generally, the radiation frequency corresponding to the preset frequency pattern is lower than a certain value, so as to reduce the SAR radiation effect of the mobile terminal.
Further, for a mobile terminal provided with a plurality of antenna structures, the millimeter wave antenna of the mobile terminal may also be switched in a switching manner, specifically, if the approaching direction is the direction corresponding to the top of the mobile terminal or the body of the mobile terminal, the millimeter wave antenna used by the mobile terminal is switched to the antenna corresponding to the bottom of the mobile terminal. The reason is that when a user usually calls, the top of the mobile terminal or the body of the mobile terminal is close to the face of the user so as to achieve the purpose of calling, and the millimeter wave antenna used by the mobile terminal can be forcibly switched to the antenna corresponding to the bottom of the mobile terminal by the switching mode, so that the radiation of the mobile terminal to the head of the user can be effectively reduced. The antenna corresponding to the bottom may be a millimeter wave antenna, or the above-mentioned 2G/3G/4G antenna, or an antenna combining millimeter waves and 2G/3G/4G frequency bands at the same time, which is based on actual use, and the embodiment of the present application does not limit this.
In addition, if the signal strength of the echo signal of each millimeter wave antenna in the mobile terminal is lower than the preset strength threshold; the millimeter wave antenna may be initialized according to a preset initial antenna power mode, and at this time, the user or user is not particularly close to the mobile terminal, so that the approach direction of the human body close to the mobile terminal does not need to be determined, and the antenna power of the mobile terminal does not need to be adjusted or switched.
Further, if the millimeter wave scanning function is determined not to be started according to the monitoring result, the identification of the SAR sensor is obtained, and the antenna power of the mobile terminal is adjusted according to a preset sensor adjusting mode.
Specifically, if an earphone starting signal is monitored and a human body approaching signal is monitored, determining that the millimeter wave scanning function is not started; or if the earphone starting signal is not monitored and the human body approaching signal is monitored, determining that the millimeter wave scanning function is not started.
When the antenna power of the mobile terminal is adjusted according to a preset sensor adjusting mode, a preset approaching direction corresponding to the identification of the SAR sensor can be obtained; determining a millimeter wave antenna corresponding to a preset approaching direction as a target millimeter wave antenna; and triggering the target millimeter wave antenna to operate according to a preset antenna power mode.
Wherein, in this application embodiment, the preset approaching direction includes: the mobile terminal comprises a front direction, a side direction and a back direction of the mobile terminal, wherein the front direction is a direction in which a receiver of the mobile terminal is located, and the back direction is a direction opposite to the front direction; each preset approaching direction corresponds to a different antenna power mode.
Specifically, the side generally refers to a side of a body of the mobile terminal, and for the sensor adjustment mode, the millimeter wave scanning function is not turned on, and the SAR sensor senses a human body approach signal. For example, if the SAR sensor in the front direction of the mobile terminal monitors a human body approach signal, the antenna power of the target millimeter wave antenna in the front of the mobile terminal may be adjusted to the a power level, if the SAR sensor in the side direction of the mobile terminal monitors a human body approach signal, the antenna power of the target millimeter wave antenna in the side of the mobile terminal may be adjusted to the B power level, if the SAR sensor in the back direction of the mobile terminal monitors a human body approach signal, the antenna power of the target millimeter wave antenna in the back of the mobile terminal may be adjusted to the C power level, and so on. The power levels a to C correspond to different antenna powers, for example, the front of the mobile terminal is close to the head of a human body, so the corresponding power level a is lower on the premise of ensuring normal communication, and the back of the mobile terminal is rarely and directly close to the head, so the corresponding power level C may be higher, and the like, and the specific power value may be set according to the actual use condition, which is not limited in the embodiments of the present application.
Specifically, for ease of understanding, fig. 3 shows a flowchart for controlling antenna power of a mobile terminal, and as shown in fig. 3, the flowchart includes the following steps:
firstly, judging whether a receiver starting signal is monitored; if so, the upper branch is executed, and if not, the lower branch is executed.
For the upper branch, whether a human body approach signal is monitored or not is further judged; if so, a sensor adjustment mode is adopted, for example, as described above, the millimeter wave antenna corresponding to the preset approaching direction is determined as the target millimeter wave antenna, the target millimeter wave antenna is triggered to operate according to the preset antenna power mode, and the like, and the power levels of the antennas in different preset approaching directions may be adjusted, for example, the antenna power of the target millimeter wave antenna on the front side of the mobile terminal is adjusted to the power level a, the antenna power of the target millimeter wave antenna on the side of the mobile terminal is adjusted to the power level B, and the antenna power of the target millimeter wave antenna on the back side of the mobile terminal is adjusted to the power level C, and the like. And if the human body approaching signal is not monitored, starting a millimeter wave scanning function, and at the moment, whether the frequency of the target millimeter wave antenna is adjusted or not or whether the millimeter wave antenna is initialized or the like can be seen according to the strength of the echo signal.
Further, for the following branch, that is, the situation that the earphone starting signal is not monitored, it is also necessary to further determine whether the SAR sensor monitors a human body approach signal, at this time, the following execution process is consistent with the above branch, that is, if the human body approach signal is monitored, the sensor adjustment mode is adopted, and if the human body approach signal is not monitored, the millimeter wave scanning function is started.
Through the control flow of the antenna power of the mobile terminal shown in fig. 3, the number of used SAR sensors can be effectively reduced, and the misjudgment caused by using other sensors, such as an acceleration sensor or a gravity sensor, can be reduced.
Further, on the basis of the foregoing embodiments, an embodiment of the present application further provides a device for controlling antenna power of a mobile terminal, where the device is applied to the mobile terminal, and as shown in fig. 4, the device for controlling antenna power of a mobile terminal includes:
