Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, a radiation control method is provided, which is applicable to a scenario for optimizing electromagnetic radiation control of a terminal, and which may be performed by a radiation control apparatus, which may be implemented in a software and/or hardware manner, and may be integrated on an electronic device. The embodiment is illustrated by applying the method to a terminal, and it can be understood that the method can also be applied to a server, and can also be applied to a system comprising the terminal and the server, and is implemented by interaction between the terminal and the server. In this embodiment, the method includes the steps of:
Among them, WIFI (WIreless Fidelity) is called WIreless Fidelity, can convert wired network information into WIreless signals, and is a WIreless network transmission technology which is most widely used today. The terminal in the embodiment of the application can be provided with the WIFI module to support data transmission through WIFI. The radiation influence data may be understood as data that can influence the SAR value of the terminal, i.e. data related to increase the SAR value, and may include various data, for example, the radiation influence data may include a distance between a user and the terminal, headset usage data reflecting a call state of the terminal, and the like.
SAR refers to the electromagnetic radiation energy absorbed by a substance of unit mass per unit time, and is commonly used internationally to measure the thermal effect of terminal radiation, with the electromagnetic radiation energy (watts) absorbed per kilogram of human tissue at any 6 minute chronogram average. For example, the radiation of the mobile phone is measured by the SAR value, which refers to the rate of absorption of the radiation by the human body, and the lower the SAR value, the less the radiation is absorbed by the human body.
Specifically, the terminal can acquire radiation influence data through a preset data acquisition device in a state that WIFI is opened, and the data acquisition device is not limited by the application and corresponds to specific data.
The radiation reduction condition refers to a specific condition that the SAR value of the terminal needs to be reduced. The State Machine (State Machine) is a control center that can perform State transition according to a preset State, and coordinates the operation of related signals to complete a specific operation. The radiation state parameter is a parameter for recording whether the transmission power is reduced, that is, whether the SAR value for the recording terminal is reduced. According to the embodiment of the application, the transmission power at different moments can be recorded through a state machine, whether the transmission power is reduced or not is determined, the result is represented by the radiation state parameter, and the radiation state parameter can be represented by numbers and/or subtitles, for example, the transmission power is represented to be reduced through 0, and the transmission power is represented to be not reduced through 1.
Specifically, after the terminal acquires the radiation influence data, the terminal can judge whether the terminal is in contact with a user or whether the terminal is in a call state according to the radiation influence data, and the like, under the condition that the SAR value is high, if so, the SAR value needs to be reduced, the radiation reduction condition is determined to be met, and the radiation state parameters recorded by the state machine are acquired.
And 103, reducing the current transmitting power based on the radiation state parameters to obtain the target transmitting power.
Wherein the radiation state parameter may include a first parameter indicating that the transmission power has been reduced and a second parameter indicating that the transmission power has not been reduced. The transmission power refers to the transmission power of the terminal in the using process, and specifically may include the transmission power of an antenna of the WIFI module and a cellular antenna of the cellular network.
Specifically, after the terminal acquires the radiation state parameters, different strategies for reducing the transmission power adopted by different radiation state parameters are different. If the radiation state parameter is the second parameter, directly reducing the current transmitting power of the terminal to obtain the target transmitting power; if the radiation state parameter is the first parameter, it indicates that the occurrence power has been reduced historically, that is, the SAR value has been reduced, and the SAR value needs to be reduced again at present, at this time, the transmission power can be restored and then reduced, and the target transmission power is obtained.
And step 104, reducing the current electromagnetic wave absorption ratio according to the target transmitting power.
The terminal has different transmitting powers in different working states, the larger the transmitting power is, the higher the SAR value is, the lower the transmitting power is, and the lower the SAR value is, so the SAR value can be reduced by reducing the transmitting power.
And the target SAR value corresponding to the target transmitting power is smaller than the current SAR value corresponding to the current transmitting power, and the SAR value is reduced after the current transmitting power is reduced.
In the radiation control method, radiation influence data is acquired in a WIFI open state; when the radiation influence data meet the radiation reduction condition, obtaining radiation state parameters recorded by a state machine; wherein, the radiation state parameter is a parameter for recording whether the emission power is reduced; reducing the current transmitting power based on the radiation state parameter to obtain target transmitting power; and reducing the current electromagnetic wave absorption ratio according to the target transmitting power. By adopting the technical scheme, the radiation state parameters are recorded through the state machine, when the radiation reduction condition is determined to be met, the reduction of the transmitting power can be more efficiently and conveniently executed according to the current radiation state parameters, so that the electromagnetic radiation is reduced, the condition of state disorder possibly occurring when more judgment conditions exist in the existing scheme is avoided, the flexibility is higher, the expansibility is better, the method is more easily suitable for various platforms and scenes, and the maintenance is easy.
In one embodiment, the radiation impact data comprises user distance from the terminal and/or headset usage data. The terminal can acquire the distance between the user and the terminal through a built-in distance sensor or determine the distance between the user and the terminal through a sensing capacitor value acquired by a sensing capacitor. The headset usage data refers to data whether or not the headset of the terminal is in use. The radiation effect data is illustrated in the present application by taking the distance between the user and the terminal and the earphone usage data as examples.
In one embodiment, the radiation impact data satisfies a radiation reduction condition comprising: the radiation reduction condition is determined to be satisfied if it is determined that the user is on a call based on the distance being less than or equal to the distance threshold and/or based on the headset usage data.
Specifically, if the terminal determines that the distance between the user and the terminal is less than or equal to the distance threshold, it is determined that the user touches the terminal, that is, the user may hold the terminal by hand or touch the terminal with a finger, and it is determined that the radiation reduction condition is satisfied. The distance threshold value can be set according to actual conditions. Or, if the terminal determines that the user is using the earphone according to the earphone usage data, it indicates that the user may be in the process of calling, and may determine that the radiation reduction condition is satisfied in the process of making a call or answering a call.
In the above scheme, under the condition that the terminal is opened under WIFI, when a user contacts the terminal or is in a conversation process, the radiation reduction condition can be determined to be met, the SAR value reduction is started, and then the SAR value can be reduced through reducing the transmission power, so that the electromagnetic radiation damage of the terminal is reduced, and the damage to the health of the user is reduced.
In one embodiment, reducing the current transmission power based on the radiation state parameter to obtain the target transmission power comprises: if the radiation state parameter is the first parameter, the current transmitting power is restored to the initial transmitting power before reduction; wherein the first parameter indicates that the transmit power has been reduced; and reducing the recovered initial transmitting power to obtain the target transmitting power. In one embodiment, reducing the current transmission power based on the radiation state parameter to obtain the target transmission power comprises: and if the radiation state parameter is a second parameter, reducing the current transmission power to obtain the target transmission power, wherein the second parameter indicates that the transmission power is not reduced.
The first parameter represents that the SAR value is lowered historically, and the second parameter represents that the SAR value is not lowered historically. In the embodiment of the present application, a radiation state parameter of a terminal is recorded by a state machine, for example, fig. 2 is a schematic diagram of the state machine in an embodiment, and the terminal may send a requirement for reducing an SAR value and a requirement for recovering the SAR value to the state machine respectively, so that the state machine performs a specific operation and performs state recording of transmission power.
Specifically, after the terminal acquires the radiation state parameter, if the radiation state parameter is the first parameter, it indicates that the situation of reducing the transmission power already exists in history, that is, the situation of reducing the SAR value exists, the SAR value needs to be reduced again at present, the current transmission power can be restored to the initial transmission power before reduction, and then the restored initial transmission power is reduced to obtain the target transmission power. And if the radiation state parameter is the second parameter, the historical transmission power is not reduced, and the current transmission power can be directly reduced to obtain the target transmission power.
In the above scheme, because the radiation state parameters of the terminal are recorded by the state machine, whether the terminal has reduced the transmission power or not can be known very easily, that is, the SAR value is also reduced, so that the reduction of the subsequent transmission power is realized relatively efficiently, the state conversion is also realized very easily, the operation is easier, the state disorder condition cannot occur, and the operation is more convenient and easier to maintain when the requirement of additionally reducing the SAR value is added.
In one embodiment, the radiation control method of the embodiment of the present application may further include: acquiring a switch state parameter of a data network; determining the reduction power of the current transmitting power based on the switching state of the data network corresponding to the switching state parameter; reducing the current transmitting power based on the radiation state parameter to obtain a target transmitting power, comprising: and reducing the current transmitting power by the reduction power based on the radiation state parameter to obtain the target transmitting power. The determination of the reduced power may be performed before the step 103.
The data network refers to a mobile communication network, and is not limited to this, for example, the data network may be a Long Term Evolution (LTE) network. Specifically, the terminal may obtain the on-off state parameter of the data network before reducing the current transmission power based on the radiation state parameter to obtain the target transmission power, judge the on-off state of the current data network based on the on-off state parameter, that is, whether the current data network is in use, and determine the reduction power of the current transmission power based on the on-off state of the data network. The reduced power refers to a specific power value required to be reduced when the current transmission power is reduced to the target transmission power, that is, a difference value between the current transmission power and the target transmission power. And then, reducing the current transmitting power by the reduced power based on the radiation state parameter to obtain the target transmitting power.
In one embodiment, determining the reduction power of the current transmission power based on the switching state of the data network corresponding to the switching state parameter includes: if the switch state corresponding to the switch state parameter is the opening state, the reduced power is the first power; and if the switch state corresponding to the switch state parameter is the closing state, the reduced power is the second power, wherein the first power is larger than the second power. The first power and the second power are used for representing different power values, the first power is far greater than the second power, specific values of the first power and the second power can be set according to actual conditions, and for example, the first power can be twice as large as the second power.
Specifically, when the terminal determines that the data network is in an open state, the data network and the WIFI are simultaneously opened, the SAR value is high, and the reduced power is determined to be first power; and when the data network is determined to be in the closed state, the WIFI is used while the data network is not used, the SAR value is not particularly high, and the reduced power is determined to be the second power. After determining the reduced power, the terminal may reduce the reduced power when reducing the current transmit power, to obtain the target transmit power.
In the scheme, the terminal can reduce the SAR value by reducing the transmission power by different values under different network states, so that the transmission power can be reduced according to actual conditions, the influence on the network state of the terminal caused by too much reduction is avoided, and the terminal is more flexible and more suitable for actual use scenes.
Exemplarily, fig. 3 is a schematic flowchart of a radiation control method in another embodiment, where a terminal is described by taking a mobile phone as an example, the radiation control method may include: 1. and when the mobile phone is started, the SAR reduction program is started simultaneously to monitor the states of the earphone (headset), the induction capacitor and the WIFI. And executing the subsequent steps in the WIFI open state. 2. When a user holds a mobile phone by hand to trigger the induction capacitor or makes a call to use the earphone, the sensing capacitor is monitored, and the starting, lifting and falling SAR steps are started. 3. Firstly, judging whether an LTE network exists at present, namely whether a data network is used, if so, backing power to be a first power value; otherwise, the back-off power is the second power value, the first power value is much larger than the second power value, for example, the first power value may be twice as large as the second power value. The back-off power refers to a specific power at which the transmission power is reduced. Because more SAR values need to be reduced if the data network and the WIFI are used simultaneously, and less SAR values need to be reduced if the WIFI is used but the data network is not used, the SAR values are reduced in the two cases with different requirements, i.e. with different back-off powers, i.e. with different values of the reduction of the transmission power. And step 304, if SAR reduction occurs, but the user triggers SAR reduction operation, the transmitting power needs to be restored to the front of SAR reduction, and then SAR reduction operation is executed by using the newly triggered SAR reduction behavior and new conditions, so that each SAR reduction operation is feedback of the latest operation of the user.
In the scheme, under the condition that the WIFI is turned on, when a user holds the mobile phone by hand or answers a call, the WIFI power is automatically reduced, and when the user does not hold the mobile phone by hand or does not use a receiver after the call is finished, the WIFI power is restored to the original power, so that the use of the WIFI is not influenced.
The radiation control method in the embodiment of the application uses the state machine to replace the traditional judgment condition, has more flexibility and better expansibility, and can be more easily adapted to more platforms; and the state machine is used for recording the terminal radiation state parameters, the current state is recorded through the state machine, whether the SAR state is currently reduced or not can be known very easily, the SAR state reduction can be converted very easily, compared with the existing scheme, the operation is easier, the state disorder condition can not occur, and the method is more convenient and easier to maintain when additional functions are added.

The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
