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 application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be implemented in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The following describes the scene environment switching method provided by the embodiment of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart of a radio frequency control method according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
Wherein the receiving a first input may be receiving a first input selecting a target radio frequency control mode; or, receiving a first input for a hardware key of the electronic device; or, receiving a first input of a user on a screen of the electronic device, for example, receiving an input of a user sliding on the screen of the electronic device according to a preset trajectory. The first input is not limited in the embodiments of the present invention.
And 102, determining a target transmission power threshold corresponding to the first input.
Wherein the receiving a first input may include: receiving a first input selecting a target radio frequency control mode; the determining a target transmit power threshold corresponding to the first input may include: and determining a target transmitting power threshold corresponding to the target radio frequency control mode according to the corresponding relation between the preset radio frequency control mode and the transmitting power threshold. Alternatively, the determining a target transmit power threshold corresponding to the first input may include: determining the target transmit power threshold based on a level signal of a General-purpose input/output (GPIO) of a chip in the electronic device, the level signal of the GPIO corresponding to the first input. Alternatively, the first input may be an input sliding on a screen of the electronic device according to a preset trajectory, and the determining the target transmit power threshold corresponding to the first input may include: and determining a target transmitting power threshold corresponding to the preset track. The embodiment of the present invention does not limit this.
And 103, detecting the radio frequency emission power of an antenna in the electronic equipment.
The radio frequency transmission power of the antenna in the electronic device may be detected in real time, or the radio frequency transmission power of the antenna in the electronic device may be detected at certain time intervals, and the like, which is not limited in the embodiment of the present invention. The detecting the radio frequency transmission power of the antenna in the electronic device may be detecting the radio frequency transmission power of the current antenna. Before the next radio frequency transmission, the radio frequency transmission power of the current antenna can be calculated according to the current communication signal strength of the electronic equipment, the last radio frequency transmission power of the antenna or other radio frequency related information. For example, the radio frequency transmit power of the present antenna may be inversely proportional to the communication signal strength of the electronic device.
And 104, if the radio frequency transmission power of the antenna is detected to be larger than the target transmission power threshold value, controlling the radio frequency transmission power of the antenna so as to enable the radio frequency transmission power of the antenna to be smaller than or equal to the target transmission power threshold value.
Wherein the radio frequency transmission power of the antenna may be related to the location of the electronic device. If the communication signal strength of the electronic equipment is weaker, the radio frequency transmitting power of the antenna can be larger; if the communication signal strength of the electronic device is strong, the radio frequency transmission power of the antenna may be small. Before performing radio frequency transmission, current radio frequency transmission power of an antenna can be detected, and if the radio frequency transmission power of the antenna is detected to be larger than the target transmission power threshold, the radio frequency transmission power of the antenna can be controlled so that the radio frequency transmission power of the antenna is smaller than or equal to the target transmission power threshold. If it is detected that the rf transmit power of the antenna is less than or equal to the target transmit power threshold, the rf transmit power of the antenna may be controlled to remain unchanged.
At present, with the rapid development of information technology, the living standard of people is continuously improved, and the people can enjoy various conveniences brought by electronic equipment and can be harmed to the health of human bodies by an electromagnetic field emitted by the electronic equipment. Therefore, in the field of research and development and testing of electronic devices, in addition to the parameters of the antenna such as TRP (omnidirectional radiated power), TIS (total omnidirectional sensitivity), RL (return loss), and Efficiency, the Specific Absorption Rate (SAR) value is also required to be concerned. The SAR value may be used to characterize the degree to which electromagnetic radiation of the electronic device affects human health. The SAR value is the electromagnetic radiation energy absorbed by the organism per unit time(s) and per unit mass (kg). Before the electronic equipment is sold, the SAR value is tested by a certification authority, and the electronic equipment is sold after meeting relevant regulations. The smaller the SAR value, the less radiation is absorbed and the less harmful it is to the human body.
In practical application, the SAR value can be evaluated from the antenna wiring form, the placement area, structural members with large influence around the antenna, radio frequency components and the like. The SAR value is in direct proportion to the radio frequency emission power of the antenna, and a mechanism for reducing the radio frequency emission power can be triggered and started when a human body approaches the electronic equipment, so that the SAR value is reduced. The inductor can be added to the electronic equipment, and when the inductor induces that a human body approaches, the radio frequency emission power of the antenna is reduced. The inductor needs to be connected to the antenna, which increases the cost of the electronic device and the complexity of the hardware circuit when the number of antennas is large. When the scene sensed by the sensor is unclear, the electronic equipment is always in a standby state, so that the power consumption of the electronic equipment is increased, and the cruising ability of the electronic equipment is reduced.
The radio frequency control method in the embodiment of the application can be preferably applied to 5G multi-antenna electronic equipment, can ensure that the performance of an application scene is maximized, can improve the protection awareness of a user on the electronic equipment, and further can reduce the SAR value of the electronic equipment in a visualized and self-selectable manner.
In the embodiment of the application, a first input is received; determining a target transmit power threshold corresponding to the first input; detecting radio frequency transmission power of an antenna in the electronic equipment; and if the radio frequency transmission power of the antenna is detected to be larger than the target transmission power threshold, controlling the radio frequency transmission power of the antenna so as to enable the radio frequency transmission power of the antenna to be smaller than or equal to the target transmission power threshold. Therefore, the radio frequency transmission power of the antenna is controlled based on the target transmission power threshold corresponding to the first input, and radiation of the antenna of the electronic equipment to a human body can be reduced.
Optionally, the receiving a first input includes:
receiving a first input selecting a target radio frequency control mode;
the determining a target transmit power threshold corresponding to the first input comprises:
and determining a target transmitting power threshold corresponding to the target radio frequency control mode according to the corresponding relation between the preset radio frequency control mode and the transmitting power threshold.
The corresponding relationship between the preset radio frequency control mode and the transmission power threshold value can be stored in the electronic device. The receiving a first input selecting a target radio frequency control mode may include: receiving a first input for a hardware key of the electronic device, wherein the first input is used for selecting a target radio frequency control mode; alternatively, at least one radio frequency control mode may be displayed, and the receiving of the first input selecting the target radio frequency control mode may include: a first input is received to select a target radio frequency control mode among the displayed at least one radio frequency control mode.
In practical application, the corresponding relation between the radio frequency transmission power of the antenna and the SAR value can be obtained. The electronic device may perform radio frequency transmission when establishing a call or data connection, and may detect an SAR value of the electronic device when performing radio frequency transmission. For example, when the radio frequency transmission power of the antenna is a, the SAR value of the electronic device is detected to be B. If the SAR value of the electronic device is defined as B in the target radio frequency control mode, the target transmission power threshold may be set as a. Taking as an example that the radio frequency control modes preset on the electronic device include four radio frequency control modes, the four radio frequency control modes may be: lower head sar, lower body sar, lower limb sar, and close sar. The transmit power threshold in the head-down sar mode may be less than the transmit power threshold in the body-down sar mode, and the transmit power threshold in the body-down sar mode may be less than or equal to the transmit power threshold in the body-down sar mode.
Taking an electronic device as an example, each radio frequency control mode may correspond to one control state, the head-lowering sar mode may correspond to the control state DSI3, the limb-lowering sar mode may correspond to the control state DSI2, the body-lowering sar mode may correspond to the control state DSI1, and the closed sar-lowering mode may correspond to the control state DSI 0. The mobile phone can be set to be in a control state DSI0 in a power-on state, the maximum radio frequency transmitting power of the mobile phone can be set to be 24dBm in a DSI0 state, the maximum radio frequency transmitting power of the mobile phone is 21dBm in a DSI1 state, the maximum radio frequency transmitting power of the mobile phone is 22dBm in a DSI2 state, and the maximum radio frequency transmitting power of the mobile phone is 22dBm in a DSI3 state. In the DSI0 state, the processor chip of the mobile phone may determine the target rf control mode, and if the processor chip determines that the mode is the DSI2 state, the processor chip may issue an instruction to the mode control module of the electronic device, and the mode control module may switch the control state from the DSI0 to the DSI 2. The processor chip of the mobile phone can control the maximum radio frequency emission power of the mobile phone to be switched from 24dBm to 22 dBm.
In addition, a preset radio frequency control mode can be displayed on a human-computer interaction interface of the electronic equipment, when a user selects a target radio frequency control mode, the electronic equipment receives input of the user selecting the target radio frequency control mode, and determines a target transmission power threshold corresponding to the target radio frequency control mode according to the corresponding relation between the preset radio frequency control mode and the transmission power threshold. And if the radio frequency transmitting power of the antenna is detected to be larger than the target transmitting power threshold, controlling the radio frequency transmitting power of the antenna so as to enable the radio frequency transmitting power of the antenna to be smaller than or equal to the target transmitting power threshold.
In the embodiment, the user can select the target radio frequency control mode, so that the electronic equipment can control the radio frequency transmitting power of the antenna according to the target transmitting power threshold value corresponding to the target radio frequency control mode, an SAR sensor does not need to be added on the electronic equipment, the cost of the electronic equipment can be reduced, and the user experience is better.
Optionally, before receiving the first input for selecting the target radio frequency control mode, the method further includes:
displaying at least one radio frequency control mode;
wherein the at least one radio frequency control mode includes the target radio frequency control mode.
In addition, at least one radio frequency control mode may be displayed on a screen of the electronic device. Each of the at least one rf control mode may be configured with a corresponding transmit power threshold. The user can select the corresponding radio frequency control mode according to the requirement. For example, the at least one radio frequency control mode may include lowering head sar, lowering body sar, lowering limb sar, and closing off lowering sar. When a user puts the electronic equipment in the pocket of the upper garment, the body sar reducing mode can be selected; when a user places the electronic equipment in the trouser pocket, the body sar lowering mode can be selected; when the user places the electronic device in proximity to the head, the heads-down sar mode may be selected; the off sar down mode may be selected when the user places the electronic device away from the user.
In this embodiment, at least one radio frequency control mode is displayed, so that a user can select a target radio frequency control mode from the displayed at least one radio frequency control mode, and the cost of the electronic device can be further reduced without adding hardware to the electronic device for radio frequency control.
Optionally, the receiving a first input selecting a target radio frequency control mode includes:
receiving a first input for a hardware key of the electronic device, the first input being used to select a target radio frequency control mode.
The number of the hardware keys can be one or more. The hardware keys can be connected with a universal input/output port of a chip in the electronic equipment. The state change of the hardware key can trigger the level signal of the general input/output port to change. For example, the number of the hardware keys may be one, the hardware keys may be connected to two general purpose input/output ports, the logic of the two general purpose input/output ports may form four control commands, and the logic of the two general purpose input/output ports may include: 00, 01, 10, 11. Each control command may correspond to a different radio frequency control mode.
For example, if a hardware key is pressed once within a preset duration, logic 00 may be triggered; pressing the hardware key twice within a preset duration can trigger logic 01; pressing the hardware key three times within a preset duration may trigger logic 10; pressing the hardware key four times within a preset duration triggers logic 11. The preset time period may be 3s, or may be 5s, or may be 10s, and the like, which is not limited in the embodiment of the present invention. Logic 00 may characterize a head-down sar mode, logic 01 may characterize a body-down sar mode, logic 10 may characterize a limb-down sar mode, and logic 11 may characterize a turn-off sar mode.
In the embodiment, a user can select the target radio frequency control mode through a hardware key without adding an SAR sensor on the electronic equipment, so that the hardware circuit design can be simplified, and the PCB layout space is saved.
Optionally, the determining a target transmit power threshold corresponding to the first input includes:
and determining the target transmitting power threshold value based on a level signal of a universal input/output port of a chip in the electronic equipment, wherein the level signal of the universal input/output port corresponds to the first input.
The first input may be configured to select a target radio frequency control mode, select different radio frequency control modes as the target radio frequency control mode, and the level signals of the general input/output port are different. Taking two general input/output ports as an example, the level signals of the two general input/output ports can form four control commands. For example, the level signals of the two general input/output ports are both high level, which may form logic 11.
In practical application, the GPIO port may be used for logic determination, and may form logic 1 and 0 by providing high level and low level, and different logic may set different control commands. The level signal of one GPIO port can represent two control commands, and the level signals of N GPIO ports can be used for representing 2NA control command. Taking an electronic device as an example of a mobile phone, a part of GPIO ports of a main chip of the current mobile phone is in an idle state, which causes waste. In this embodiment, the target transmission power threshold may be determined by using a level signal of a general input/output port of a chip in the electronic device. For example, the level signals of the two GPIO ports may be used to form 4 control commands, which are respectively a head-down sar, a body sar, a limb sar, and a closing sar, and the level signals of the two GPIO ports may be transformed by a control button displayed on a human-computer interface on the electronic device, so as to implement issuing an sar reduction command, thereby achieving the function of reducing the sar value of the electronic device.
In this embodiment, the target transmit power threshold is determined based on a level signal of a general input/output port of a chip in the electronic device, where the level signal of the general input/output port corresponds to the first input, and radio frequency control can be implemented by using the general input/output port of the chip in the electronic device, so that complexity of hardware circuit design can be reduced, and cost of the electronic device can be further reduced.
