Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a flow chart illustrating an antenna control method according to an example embodiment. The method can be applied to electronic equipment such as a mobile phone, a smart watch, a tablet computer, a notebook computer and the like, and the type of the electronic equipment is not limited by the embodiment of the disclosure. As shown in fig. 1, the method may include:

step 100, obtaining a measurement result obtained by a sensor of the electronic device performing distance measurement.

And step 101, judging whether an object approaches the electronic equipment or not according to the measurement result.

And 102, controlling a plurality of antennas in the electronic equipment to transmit signals in turn when the object is judged to be close to the electronic equipment.

In the embodiment of the present disclosure, the sensor of the electronic device may be a Distance sensor (Distance sensor), and in general, the Distance sensor, which may also be referred to as a displacement sensor, may be used to detect a Distance between the sensor and the detected object. The distance sensor may be, for example, an optical distance sensor, an ultrasonic distance sensor, or the like. It should be noted that other types of sensors may also be selected as the sensor of the electronic device, as long as the sensor can detect the distance between the electronic device and the detected object around the electronic device, and the type of the sensor is not limited in the embodiments of the present disclosure.

The processor of the electronic Device may be implemented by one or more Application Specific Integrated Circuits (ASICs), Digital Signal Processors (DSPs), Digital Signal Processing Devices (DSPDs), Programmable Logic Devices (PLDs), Field Programmable Gate Arrays (FPGAs), controllers, microcontrollers, microprocessors, or other electronic components, and the type of processor is not limited by the disclosed embodiments.

As an example of the present embodiment, the processor of the electronic device may control the sensor to perform distance measurement, and acquire a measurement result obtained by the sensor performing distance measurement; the sensor may also perform the distance measurement automatically after power-up, and the processor may acquire the measurement results of the distance measurement performed by the sensor, for example, at a preset frequency.

The sensor may emit a detection signal (e.g., the detection signal may be an infrared ray, an ultrasonic wave, a radio signal, or the like) when performing the distance measurement, and may receive a detection signal reflected by an object (e.g., the object may be a living body or a non-living body) around the electronic device.

In one possible implementation, the sensor may determine the strength of the reflected detection signal (an example of a measurement). The processor may acquire the intensity of the reflected detection signal from the sensor, and may determine whether an object approaches the electronic device according to a comparison result between the intensity of the reflected detection signal and a preset signal threshold. For example, when the acquired detection signal intensity is not less than the signal threshold, it is determined that an object is close to the electronic device; and when the acquired detection signal strength is smaller than the signal threshold, judging that no object approaches the electronic equipment.

In one possible implementation, the sensor may determine a reaction time period (another example of a measurement) from the emission of the detection signal to the reception of the reflected detection signal. The processor may acquire the reaction duration from the sensor, and may determine whether an object is close to the electronic device according to a comparison result between the acquired reaction duration and a preset duration threshold. For example, when the obtained reaction duration is greater than or equal to the duration threshold, it is determined that no object is close to the electronic device; and when the obtained reaction time length is less than the time length threshold value, judging that an object approaches the electronic equipment.

In one possible implementation, the sensor may receive the reflected detection signal and determine a distance value (another example of a measurement) between the electronic device and a surrounding object according to the reflected detection signal strength, the processor may acquire the distance value from the sensor, the processor may determine that an object is close to the electronic device if the distance value is less than or equal to a distance threshold, and the processor may determine that no object is close to the electronic device if the distance value is greater than the distance threshold.

It should be noted that, the embodiment of the present disclosure does not limit the specific manner of determining whether an object is close to the electronic device according to the measurement result.

The processor may control all antennas in the electronic device to transmit signals in turn when it is determined that an object is close to the electronic device. For example, if three antennas, namely, a first antenna, a second antenna and a third antenna, are provided in the electronic device, the processor may control the first antenna to transmit signals between a first time and a second time later than the first time, the second antenna and the third antenna do not transmit signals, then, the processor may control the second antenna to transmit signals between the second time and a third time later than the second time, the first antenna and the third antenna do not transmit signals, and finally, the processor may control the third antenna to transmit signals between the third time and a fourth time later than the third time, the first antenna and the second antenna do not transmit signals, and the processor may repeat the above processes until the processor determines that no object is close to the electronic device, wherein the duration from the first time to the second time, the duration from the second time to the third time, and the duration from the third time to the fourth time may be completely the same, Different from each other or partially identical.

In a possible implementation manner, the electronic device may also control any part of all antennas of the electronic device to transmit signals in turn when it is determined that an object is close to the electronic device, for example, the electronic device includes four antennas, and the electronic device may control two of the four antennas to transmit signals in turn when it is determined that an object is close to the electronic device.

It should be noted that other suitable manners may be selected according to the need of reducing the SAR value of the electronic device to control the multiple antennas in the electronic device to transmit signals in turn.

The sensor of the electronic equipment is controlled to carry out distance measurement to obtain a measurement result, and when an object is judged to be close to the electronic equipment according to the measurement result, the plurality of antennas in the electronic equipment are controlled to transmit signals in turn.

Fig. 2 is a flow chart illustrating an antenna control method according to an example embodiment. As shown in fig. 2, the difference between fig. 2 and fig. 1 is that the method further comprises: and 200, when judging that no object approaches the electronic equipment, controlling any one of a plurality of antennas in the electronic equipment to transmit signals.

As an example of this embodiment, the processor of the electronic device may exit a state of controlling the plurality of antennas to transmit signals in turn when it is determined that no object is close to the electronic device, and may determine one antenna from the plurality of antennas and control the antenna to transmit signals (for example, the processor may randomly determine one antenna from the plurality of antennas and control the antenna to transmit signals). Therefore, the embodiment of the disclosure can control the plurality of antennas to transmit signals in turn only when an object is close to the electronic device, and control any one of the plurality of antennas to transmit signals when no object is close to the electronic device, which is beneficial to reducing the energy consumption of the electronic device.

In one possible implementation, step 102 may include: and controlling part or all of the antennas to transmit signals in turn for a preset time length by a selector switch of the electronic equipment.

As an example of the embodiment, the predetermined time period may be set according to an empirical value, for example, and when it is determined that an object approaches the electronic device, the processor may send the control signal to each antenna in turn based on the predetermined time period, that is, each antenna transmits a signal for a predetermined time period each time, and then switches to transmit a signal for the next day, thereby controlling each antenna of the plurality of antennas of the electronic device to transmit a signal in turn based on the predetermined time period.

In one possible implementation, the predetermined time period may be an integer multiple of a time slot of a signal transmitted by the electronic device antenna. Therefore, the communication data transmitted by each time slot can be effectively prevented from being intercepted by signal switching among the antennas, and the integrity of the communication data is effectively ensured. For example, if the slot in which the antenna transmits the signal is 2.5ms (milliseconds), and the multiple is 2 times the slot in the signal, the predetermined time length may be 5 ms.

In one possible implementation, the predetermined time period may be less than a period of the electromagnetic wave absorption ratio test. Therefore, the phenomenon that the total amount of the transmitting power of the same antenna exceeds the standard in the period of the electromagnetic wave absorption ratio test can be effectively avoided, and the effect of reducing the SAR value of the electronic equipment is ensured.

In one possible implementation manner, the predetermined time period may be an integral multiple of a time slot of a signal transmitted by the electronic device antenna, and the predetermined time period may be less than a period of an electromagnetic wave absorption ratio test. Therefore, the communication data transmitted by each time slot can be effectively prevented from being cut off by signal switching among the antennas, and the phenomenon that the total amount of the transmitting power of the same antenna exceeds the standard in the period of the electromagnetic wave absorption ratio test can be effectively avoided.

In the disclosed embodiments, the diverter switch may be represented as a component for controlling the switching of the various circuits in the system.

As an example of the embodiment, when determining that an object is close to the electronic device, the processor may control the switch to enter a state in which the transmission signal is alternately transmitted among the plurality of antennas, thereby controlling each of the plurality of antennas of the electronic device to transmit the signal in turn. Therefore, the processor can control the plurality of antennas to transmit signals in turn only by the selector switch without additional line connection between the processor and each antenna, thereby effectively reducing the complexity of the electronic equipment circuit,

it should be noted that, according to the number of the antennas of the electronic device, the switch may be, for example, a Double Pole Double Throw (DPDT) switch, a Double Pole Double Throw (Double Pole Double Throw) switch, a triple Pole triple Throw (triple Pole triple Throw) switch, and the disclosure does not limit the type of the switch.

In one possible implementation, the spacing between the antennas of the electronic device is greater than a preset distance. For example, if the electronic device is provided with two antennas, one of the antennas may be disposed on one side of the electronic device and the other antenna may be disposed on the other side of the electronic device. In this way, the antennas of the electronic device are dispersedly arranged at the preset distance, so that the density of electromagnetic waves in the surrounding space of the electronic device can be reduced, the total amount of the transmitting power of the same antenna in unit time can be further reduced, and the SAR value of the electronic device can be reduced. It should be noted that the preset distance may be set according to an empirical value, for example, and the setting of the preset distance is not limited in the embodiment of the present disclosure.

Taking an example where an electronic device includes two antennas, fig. 3 is a circuit schematic diagram of an electronic device shown according to an exemplary embodiment. As shown in fig. 3, the electronic device may include a first antenna, a second antenna (an example of a plurality of antennas), a detection signal transmitting module, a detection signal receiving module, a sensor chip (wherein the detection signal transmitting module, the detection signal receiving module, and the sensor chip may constitute an example of a sensor), a CPU (Central Processing Unit, an example of a processor), a radio frequency chip, and a DPDT (an example of a switch). The first antenna may be disposed on one side of the electronic device, and the second antenna may be disposed on the other side of the electronic device; the CPU may be electrically connected to the sensor chip, for example, through I2C (two-wire serial bus), and the sensor chip may be electrically connected to the detection signal transmitting module and the detection signal receiving module, respectively; the CPU may be electrically connected to the rf chip, for example, through a MIPI Interface (Mobile Industry Processor Interface) or a UART (Universal Asynchronous Receiver Transmitter), the CPU may also be electrically connected to the DPDT, for example, through a MIPI Interface or a GPIO (General Purpose Input/Output), and the DPDT may be electrically connected to the rf chip, the first antenna, and the second wire, respectively.

The CPU can control the sensor chip to carry out distance detection on objects in a preset range at a preset frequency, in each distance detection, the sensor chip can control the detection signal transmitting module to transmit a detection signal, the detection signal receiving module can receive the detection signal reflected by the objects around the electronic equipment, the sensor chip can acquire the reflected detection signal and can determine the signal intensity of the reflected detection signal, and the CPU can acquire the determined signal intensity from the sensor chip and can compare the signal intensity with a detection threshold value. The CPU may determine that no object is close to the electronic device when the signal strength obtained by the comparison is smaller than the detection threshold, and may control only the first antenna (or only the second antenna) to transmit the signal. The CPU may determine that an object is close to the electronic device when the signal strength obtained by the comparison is greater than the detection threshold, and may control the DPDT to enter a state where the transmission signal is transmitted alternately between the first antenna and the second antenna until the CPU detects that the acquired signal strength is less than the detection threshold, and may control the DPDT to exit the state where the transmission signal is transmitted alternately between the first antenna and the second antenna, and may control only the first antenna (or only the second antenna) to transmit the signal. When the CPU controls the DPDT to enter a state of transmitting signals between the first antenna and the second antenna alternately, the first antenna and the second antenna can transmit the signals alternately for a preset time. The predetermined time period may be an integer multiple of the time slot for transmitting the signal by the antenna and less than the time required for one SAR test, and in one possible implementation, the adjustment range of the predetermined time period may be from 5ms to 5s (seconds), and different predetermined time periods may be set, for example, by adjusting parameters of a CPU register. In an application example, the antenna transmission power of the electronic device when the embodiment of the disclosure is applied may be higher by about 3dB (decibel) compared to the antenna transmission power of the electronic device when the related art is applied.
