All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that the terms "comprising" and "having" and any variations thereof in the embodiments and figures herein are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
The embodiment of the application discloses a method and a device for adjusting specific absorption rate, electronic equipment and a storage medium, which can improve the accuracy of adjusting the specific absorption rate. The following will describe in detail.
Referring to fig. 1, fig. 1 is a flow chart of a specific absorption rate adjustment method according to an embodiment of the present disclosure. The method for adjusting the specific absorption rate described in fig. 1 is applicable to electronic devices such as mobile phones, tablet computers, wearable devices and the like, and the embodiment of the application is not limited.
In this embodiment of the application, the electronic device includes a radio frequency module and a motherboard, where the radio frequency module includes an antenna.
The radio frequency module may be a module for wireless communication and may include an antenna for receiving and transmitting wireless signals, a transceiver, a filter, a power amplifier, and the like.
The motherboard includes a Central Processing Unit (CPU) that is operable to control the operation of the various components of the electronic device.
As shown in fig. 1, the method for adjusting the specific absorption rate may include the steps of:
101. and determining the current equipment state of the electronic equipment according to the connection state of the coaxial line between the antenna and the main board.
The electronic equipment determines the current equipment state of the electronic equipment according to the connection state of the coaxial line between the antenna and the main board; the device states include a complete machine coupling state and a conduction test state.
The coaxial line is used for connecting the antenna and the main board, and after the electronic equipment receives the wireless signal through the antenna, the wireless signal can be transmitted from the antenna to the main board through the coaxial line so as to process the wireless signal.
As an optional implementation manner, the electronic device may determine, according to the state information input by the user, a connection state between the antenna and the coaxial line, so as to determine a device state in which the electronic device is currently located; the state information may include two connection states of the antenna connected to the coaxial line or disconnection of the antenna from the coaxial line.
As another optional implementation manner, the determining, by the electronic device, the device state in which the electronic device is currently located according to the connection state of the coaxial line between the antenna and the motherboard may include the following steps:
the electronic equipment determines the level state of the antenna corresponding to the connecting end of the coaxial line; if the level state is low level, the antenna is connected with the coaxial line, and the current equipment state of the electronic equipment is determined to be a complete machine coupling state; if the level state is high level, the antenna is disconnected from the coaxial line, and the current equipment state of the electronic equipment is determined to be a conduction test state.
In some embodiments, the electronic device determines a level state of the antenna corresponding to the connection end of the coaxial line, and may access a level detection module at the connection end of the antenna and the coaxial line, and detect the level state of the antenna corresponding to the connection end of the coaxial line through the level detection module.
Illustratively, the level detection module may be a General Purpose Input Output (GPIO) detection module, which may be configured to detect a level state corresponding to the port; alternatively, the level detection module may be a voltage comparator, which is not limited in particular.
Optionally, the coaxial line may include an inner conductor and an outer shielding layer, when the coaxial line between the antenna and the main board is disconnected, the inner conductor of the coaxial line is in an open state, the outer shielding layer is shorted to the ground, the inner conductor is disconnected from the outer shielding layer, and the signal path is cut off, so that the voltage difference between the inner conductor and the outer shielding layer is large, and the connection end of the antenna and the coaxial line can output a high level; when the antenna is connected with the coaxial line between the main board, the conductor inside the coaxial line is connected with the shielding layer outside the coaxial line through a capacitor, a low-pass filter is formed between the conductor inside the coaxial line and the shielding layer outside the coaxial line, high-frequency signals are prevented from entering, and the connection end of the antenna and the coaxial line can output low level.
The coupling state of the whole machine can be a system state formed by interaction and mutual influence among all components in the electronic equipment; further, the coupling state of the whole machine may include a coupling test state and a coupling use state, the coupling test state may be a state in which electromagnetic energy radiated when the electronic device is in contact with a human body is tested, and the coupling use state may be a state in which a user actually uses the electronic device.
The conduction test state may be a state in which electromagnetic conduction test is performed on the electronic device with the test device, for example, conduction test such as electromagnetic compatibility or radio wave radiation test may be performed on the electronic device by the test device.
When the antenna is connected with the coaxial line, the antenna transmits a wireless signal to the main board through the coaxial line, and the antenna and the main board form a whole body, so that the electronic equipment is in a complete machine coupling state; when the antenna is disconnected from the coaxial line, the electronic equipment is in a non-complete machine state, and the electronic equipment is not required to be in a complete machine state when conducting test is performed on the electronic equipment, for example, the conduction test can be directly performed on a main board of the electronic equipment to test the electromagnetic radiation performance of the electronic equipment, so that the electronic equipment can be in a conducting test state when the antenna is disconnected from the coaxial line.
102. If the current equipment state of the electronic equipment is the complete machine coupling state, acquiring a specific absorption rate SAR threshold value and a power threshold value corresponding to the SAR threshold value corresponding to the complete machine coupling state, and controlling the radio frequency module to work with a first power not larger than the power threshold value.
If the current equipment state of the electronic equipment is the complete machine coupling state, the electronic equipment acquires a specific absorption rate SAR threshold value and a power threshold value corresponding to the SAR threshold value corresponding to the complete machine coupling state, and controls the radio frequency module to work with first power which is not greater than the power threshold value.
When the electronic equipment is in a complete machine coupling state, electromagnetic radiation of the electronic equipment is mainly radiated into the air in a wireless electromagnetic wave mode and is absorbed by a human body, and particularly in states such as conversation, the human body is exposed to more electromagnetic radiation; therefore, to ensure that the human body is not subjected to excessive electromagnetic radiation, it is necessary to reduce the SAR of the electronic device by reducing the power of the electronic device.
The specific absorption rate SAR threshold corresponding to the coupling state of the whole machine may be an international standard SAR, or a SAR formulated according to standards of different countries.
The power threshold corresponding to the SAR threshold may be a threshold of radio frequency power of a radio frequency module in the electronic device; wherein, the radio frequency power is the power level of electromagnetic waves emitted by the electronic device in the wireless communication process.
Optionally, the radio frequency power of the electronic device may be calculated according to SAR, absorption capacity of the human body, and a time period of the electronic device transmitting the electromagnetic wave; for example, the radio frequency power may be the product of SAR, the body weight of the human body, and the duration of the emitted electromagnetic wave, where SAR may be the specific absorption rate in watts/kg, body weight in kg, and time in seconds. Therefore, in the case where the SAR threshold is known, a power threshold corresponding to the SAR threshold can be calculated.
Therefore, when the electronic equipment is in the complete machine coupling state, the radio frequency module is controlled to work with the first power which is not more than the power threshold, so that SAR of the electronic equipment can be effectively reduced.
103. And if the current equipment state of the electronic equipment is a conduction test state, controlling the radio frequency module to work with the second power.
If the current equipment state of the electronic equipment is a conduction test state, the electronic equipment controls the radio frequency module to work with the second power; the second power is greater than or equal to the first power. The first power and the second power may be working powers of radio frequency modules in the electronic device, i.e. radio frequency power.
It should be noted that, when the electronic device is in the conduction test state, the electronic device transmits the electromagnetic radiation signal to the test device for testing in a conduction manner, so that the human body is not excessively exposed to the electromagnetic radiation, for example, the electromagnetic radiation signal can be conducted between the electronic device and the test device in a physical contact manner, specifically, the test device can be connected to an interface (such as an antenna, wi-Fi, bluetooth interface, etc.) of the electronic device through a data line, and therefore, the electromagnetic radiation signal generated by the operation of the electronic device can be transmitted to the test device through the data line through the interface. The electromagnetic radiation level of the electronic device may be obtained by analyzing the electromagnetic radiation by the test device.
Because the electronic equipment is in the conduction test state, the influence on the human body is small, the SAR of the electronic equipment is not required to be reduced, and the conduction test of the electronic equipment under normal working power can be ensured, so that the test result of the conduction test is more accurate.
Therefore, when the electronic equipment is in the conduction test state, the radio frequency power can be controlled to work at the second power which is larger than or equal to the first power, and SAR is not required to be reduced by reducing the working power of the radio frequency module.
According to the embodiment of the application, the complete machine coupling state and the conduction test state of the electronic equipment can be accurately identified, and the power of the radio frequency module of the electronic equipment is respectively adjusted according to different adjustment strategies under different equipment states, so that different adjustment of the contrast absorption rate under different application scenes is realized, and the accuracy of the adjustment of the contrast absorption rate can be improved.
Referring to fig. 2, fig. 2 is a flow chart of another specific absorption rate adjustment method according to an embodiment of the present disclosure. The method for adjusting the specific absorption rate described in fig. 2 is applicable to electronic devices such as mobile phones, tablet computers, wearable devices and the like, and the embodiment of the application is not limited. The electronic equipment comprises a radio frequency module and a main board, and the radio frequency module comprises an antenna.
As shown in fig. 2, the method comprises the steps of:
201. and determining the current equipment state of the electronic equipment according to the connection state of the coaxial line between the antenna and the main board.
The device states include a complete machine coupling state and a conduction test state.
In one embodiment, referring to fig. 3, fig. 3 is a schematic software structure of an electronic device according to an embodiment of the present application; as shown in fig. 3, the software architecture of the electronic device 300 may include an application layer 301, a system framework layer 302, and a driver layer 303;
specifically, the system framework layer 302 is a core portion of the operating system of the electronic device, providing various system-level services and management; the system framework layer 302 may also provide an application program interface for the application layer 301 to call functions of the system, such as a network communication function, a file operation function, a message notification function, and the like;
the application layer 301 may include an application program, which is the most direct interface with the user; the application layer 301 communicates with the system framework layer 302 through an application program interface provided by the system framework layer 302;
the driver layer 303 is an interface layer between software and hardware of the electronic device for providing a driver of the hardware.
The application layer 301 may acquire an operation of the user for the application program, and the system framework layer 302 converts the operation of the user for the application program in the application layer 301 into an instruction sent to the driving layer 303; the driver layer 303 may convert the instructions provided by the system framework layer 302 into a driver for the hardware, thereby implementing control and management of the hardware in the electronic device.
As an embodiment, before determining the device state in which the electronic device is currently located according to the connection state of the coaxial line between the antenna and the motherboard, the electronic device further performs the following steps:
monitoring a coaxial line state broadcast signal, wherein the coaxial line state broadcast signal is triggered and sent when the connection state of the coaxial line between the antenna and the main board is changed; the coaxial line state broadcast signal carries change event information corresponding to the coaxial line, and the change event information is used for indicating the connection state of the coaxial line between the antenna and the main board after the coaxial line is changed;
therefore, the electronic device determining the current device state of the electronic device according to the connection state of the coaxial line between the antenna and the motherboard may include the following steps:
if the coaxial line state broadcast signal is received, determining the current equipment state of the electronic equipment according to the change event information carried in the coaxial line state broadcast signal.
It should be noted that broadcasting is an event notification mechanism in the system framework layer 302 of the electronic device; the system framework layer 302 may send events occurring in the system to the application layer 301 in the form of broadcast signals, which may include changes in network status of the electronic device, system start-up, etc., to facilitate the application layer 301 in timely knowing about the events occurring in the system and the changes in system status.
Therefore, when the connection state of the coaxial line between the antenna and the motherboard changes, the system framework layer 302 may send the event to the application layer 301 in the coaxial line state broadcast signal, and the application layer 301 may determine the device state of the electronic device according to the change event information carried in the coaxial line state broadcast signal.
Specifically, the level state of the antenna corresponding to the connection end of the coaxial line is low level, the antenna is connected to the coaxial line, and the driving layer 303 converts the event into a key event, such as a down event; the level state of the antenna corresponding to the connection end of the coaxial line is high, the antenna is disconnected from the coaxial line, and the driving layer 303 converts the event into a case event, such as an up event.
The steps are used for converting the change of the connection state of the antenna and the coaxial line into the key event, so that the electronic equipment can accurately and efficiently identify the coupling state and the conduction test state of the whole machine according to the key event.
When the connection state of the coaxial line between the antenna and the main board changes, the driving layer 303 converts the change event into a key event and reports the key event to the system frame layer 302; when receiving a key event corresponding to the coaxial line sent by the driving layer 303, the system frame layer 302 sends a coaxial line state broadcast signal to the application layer 301; the coaxial line state broadcast signal carries change event information corresponding to the coaxial line, and the change event information is used for indicating the connection state of the coaxial line between the antenna and the main board after the coaxial line is changed; the connection state indicated by the change event information may include that the antenna is connected to the coaxial line or that the antenna is disconnected from the coaxial line.
The application layer 301 monitors the coaxial line state broadcast signal, and if the application layer 301 receives the coaxial line state broadcast signal, the device state of the electronic device is determined according to the change event information carried in the coaxial line state broadcast signal; if the change event information indicates that the antenna is connected with the coaxial line, the application layer 301 may determine that the current device state of the electronic device is a complete machine coupling state; if the change event information indicates that the antenna is disconnected from the coaxial line, the application layer 301 may determine that the device state in which the electronic device is currently located is a conduction test state.
If the current equipment state of the electronic equipment is a complete machine coupling state, the application layer 301 may acquire a specific absorption rate SAR threshold and a power threshold corresponding to the SAR threshold corresponding to the complete machine coupling state, and input the power threshold to a transmit power interface provided by the system frame layer 302, so that the system frame layer 302 generates an instruction sent to the driving layer 303 according to the power threshold; the driver layer 303 may generate a driver of the hardware according to the instruction to adjust a transmit power output by a Power Amplifier (PA) of a radio frequency module in the electronic device, so as to implement that the radio frequency module operates with a first power not greater than a power threshold.
If the current device state of the electronic device is a conduction test state, the application layer 301 may acquire the second power, and input the second power to the transmit power interface provided by the system frame layer 302, so that the system frame layer 302 generates an instruction sent to the driving layer 303 according to the second power; the driver layer 303 may generate a driver of the hardware according to the instruction to control a transmit power output by a Power Amplifier (PA) of the radio frequency module in the electronic device, so as to implement the radio frequency module to operate with the second power.
As another embodiment, before determining the device state in which the electronic device is currently located according to the connection state of the coaxial line between the antenna and the motherboard, the electronic device further performs the following steps:
monitoring a database setting event, wherein the database setting event is triggered when the connection state of the coaxial line between the antenna and the main board is changed, and the state identifier stored in the database is set according to the changed connection state;
therefore, the electronic device determining the current device state of the electronic device according to the connection state of the coaxial line between the antenna and the motherboard may include the following steps:
if the database setting event is detected, a latest set state identifier is obtained from the database, and the current equipment state of the electronic equipment is determined according to the latest set state identifier.
