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.

First, ultra Wide Band (UWB) technology will be described.

Currently, UWB is used for accurate positioning, and specifically includes the following three roles:

(1) And measuring the Time of flight (TOF) of the signal between the base station and the tag to realize ranging.

(2) Time of Arrival (Time Difference of Arrival, TDOA): the signal is positioned by the time difference of the label reaching each base station, and the positioning precision can reach CM level.

(3) The Arrival Phase Difference (Phase Difference Of Arrival, PDOA): the arrival angle phase is used for measuring the azimuth relation between the base station and the label.

The distance between the human body and the electronic equipment is detected through the UWB technology, and the SAR sensor can be replaced.

The method for adjusting the antenna transmission power provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1, an embodiment of the present application provides a method for adjusting antenna transmission power, which is applied to an electronic device, and the method specifically includes the following steps:

step 101, sending a detection signal through a first ultra-wideband antenna;

optionally, when the first ultra-wideband antenna is in an Idle mode (Idle mode), the sounding signal is a first sounding signal sequence; or when the first ultra-wideband antenna is in a working mode, the detection signal is a second detection signal sequence; the second detection signal sequence is a ranging sequence or an angle measurement sequence.

102, receiving a first reflected signal of the detection signal through a second ultra-wideband antenna, and receiving a second reflected signal of the detection signal through a third ultra-wideband antenna;

as shown in fig. 2, a system block diagram of a common Ultra Wide Band (UWB) is shown. In fig. 2, SR100T is a secure precision ranging chipset, RFC, RF1, RF2, RF3, RF4 are ports, TRX _ com corresponds to ANT1, RX _ H corresponds to ANT2, RX _ V corresponds to ANT3, ANT1 can transmit and receive, ANT2 and ANT3 can receive in a time-sharing manner; TRX _ shared only ranges. Here, ANT1, ANT2, and ANT3 form an antenna array, which enables 3D Angle of arrival (AoA) measurement.

Based on this system example, the first ultra-wideband antenna in this application is ANT1, the second ultra-wideband antenna is ANT2, and the third ultra-wideband antenna is ANT 3.

103, determining position information of the human body relative to the electronic equipment according to the first reflection signal and the second reflection signal;

and 104, adjusting the maximum transmitting power of the target antenna according to the position information.

It should be noted that the electronic device includes a plurality of data antennas for transmitting the traffic data therein, and the data antennas are distributed at different positions in the electronic device. The step can determine a target antenna close to the human body from the plurality of data antennas according to the position information, thereby adjusting the maximum transmitting power of the target antenna.

In the above embodiment, the UWB technology is used to identify whether a human body is close to the electronic device, and the maximum transmission power of the target antenna is adjusted, so that the SAR sensor can be omitted, the occupation of the space of the electronic device by deploying the SAR sensor can be avoided, and the cost for deploying the SAR sensor can be reduced.

In a specific embodiment of the application, the determining, according to the first reflected signal and the second reflected signal, position information of a human body relative to the electronic device includes:

determining the relative distance of the human body relative to the electronic equipment according to the first reflection signal and/or the second reflection signal;

under the condition that the relative distance is smaller than a preset threshold value, determining the position information of the human body relative to the electronic equipment according to the first distance and the second distance; wherein the first distance is measured from the first reflected signal and the second distance is measured from the second reflected signal.

As an implementation manner, based on the UWB system shown in fig. 2, when it is detected that the earpiece is turned on, the electronic device starts to emit a specific short sequence (the sequence coding is different from the ranging and angle measuring sequence) on the ANT1 for detecting the relative distance between the electronic device and the human body, and the ANT2 and the ANT3 receive the reflected short sequence emitted by the ANT1 within a very short time t (t is less than or equal to 20cm/c, and c is the speed of light), and based on the round-trip propagation time of the electromagnetic wave, the relative distance between the electronic device and the human body can be obtained, where t changes from large to small, and distance changes from large to small. Namely, the method directly measures the relative distance between the electronic equipment and the human body by using the ranging principle of UWB.

As another implementation manner, based on the UWB system of fig. 2, the ANT1 is used to transmit a signal, and the ANT2 and ANT3 are used to detect the strength of the reflected signal, so as to determine the relative distance between the electronic device and the human body. Specifically, the corresponding relationship between the attenuation value and the distance of the signal after reflection can be obtained in advance and stored in the electronic device. It can be understood that the large distance attenuation value is large, the small distance attenuation value is small, and the large distance attenuation value and the small distance attenuation value have a certain corresponding relation, so that the relative distance between the electronic equipment and the human body can be judged by detecting the signal intensity of the reflected signal.

Specifically, when the relative distance is smaller than a first threshold (such as 10 cm), the position information of the human body relative to the electronic equipment is judged; when the relative distance is smaller than a second threshold (such as 0.5 cm), it is determined that an object is close to the electronic device, the relevant mechanism of the SAR is in effect, and the electronic device starts to reduce the maximum transmission high power of the data antenna.

In a specific embodiment of the application, the determining a relative distance between a human body and the electronic device according to the first reflection signal and the second reflection signal includes:

determining a first distance corresponding to a first signal strength of the first reflection signal and a second distance corresponding to a second signal strength of the second reflection signal according to a corresponding relation between the signal strength and the distance;

and determining the minimum value of the first distance and the second distance as the relative distance between the human body and the electronic equipment.

In particular implementations, when the UWB is in idle mode, ANT1 transmits an arbitrary sequence and ANT2, ANT3 receive the reflected signal. By acquiring the signal intensity of the reflected signal and utilizing the corresponding relation between the distance acquired in advance and the attenuation value, the relative distance between the human body and the electronic equipment can be obtained.

In a specific implementation, when the UWB is in an operating mode, the ANT1 transmits a sequence for ranging or angle measurement, and the ANT2 and the ANT3 receive the ranging or angle measurement sequence and also receive a reflected signal. Because the human body is relatively close, the reflected signal is usually obviously stronger than the signal for distance measurement or angle measurement, and the time of the reflected signal is earlier than that of the signal for distance measurement or angle measurement, software can easily distinguish which signals are reflected from the human body from all the received signals (if the signals are weak late, the signals are far from the human body, and an SAR detection mechanism is not triggered), and the relative distance between the human body and the electronic equipment can be obtained based on the corresponding relation between the signal intensity attenuation value of the reflected signal and the distance.

determining a third distance of the human body relative to the electronic equipment according to the first reflection signal;

determining a fourth distance of the human body relative to the electronic equipment according to the second reflection signal;

when the third distance is smaller than the fourth distance, determining that the first position of the electronic equipment is close to the human body; the first position is a position of the second ultra-wideband antenna in the electronic device;

when the third distance is larger than the fourth distance, determining that the second position of the electronic equipment is close to the human body; the second position is a position of the third ultra-wideband antenna in the electronic device.

Exemplarily, as shown in fig. 3, assuming that the data antennas are arranged at the upper side and the right side of the electronic device, the ultra-wideband antenna ANT2 is located at the upper side of the electronic device, and the ultra-wideband antenna ANT3 is located at the left side of the electronic device, the ANT2 and ANT3 may be operated in time division. By using the UWB ranging principle, when the screen of the electronic equipment faces the head of a human body, different distances can be obtained through the ANT2 and the ANT3, and when the distance detected by the ANT2 is smaller than that detected by the ANT3, the data antenna positioned on the upper side of the electronic equipment can be judged to be closer to the human body; when the ANT3 detects a distance smaller than that of the ANT2, it may be determined that the data antenna located at the right side portion of the electronics is closer to the human body.

It should be noted that, based on the UWB system shown in fig. 2, ANT1 may also be used for ranging when ANT2 and ANT3 are simultaneously used for SAR detection, and in this case, ANT2 and ANT3 may be periodically used for SAR detection to take into account ranging and angle measurement modes. The period T is related to the movement speed v of the electronic equipment, and T is less than 1cm/v. Here, the period T may be adjusted according to the actual effects of ranging and SAR detection. When T is too large, SAR detection is not timely enough, and when T is too small, the time length of the original sequence of ranging/distance measurement can be occupied.

Referring to fig. 4, T2 is a time length of ranging/angle measurement, and T2 is a fixed value in different operation modes of the UWB protocol. Here, T needs to be greater than T2 to minimize the normal ranging/goniometry time of UWB. Meanwhile, T1 is more than T-T2, so that a guard interval is reserved, and the interference of SAR detection on the normal work of UWB is reduced. It should be noted that there may be multiple angle measurement sequences in this period T, and the period T2 may also be a single one, which may be adjusted according to actual effects.

In the above embodiment, the ranging principle supported by UWB is used to replace the SAR sensor, so as to detect the relative distance and the relative position between the electronic device and the human body, avoid the occupation of the space of the electronic device by deploying the SAR sensor, and reduce the cost for deploying the SAR sensor.

acquiring a first signal strength of the first reflected signal and a second signal strength of the second reflected signal;

determining that a first location of the electronic device is close to a human body when P1-Pr2< a × (P1-Pr 3); the first position is a position of the second ultra-wideband antenna in the electronic device;

when P1-Pr2 > a x (P1-Pr 3), determining that the second position of the electronic equipment is close to the human body; the second position is a position of the third ultra-wideband antenna in the electronic device;

wherein P1 is the transmission power of the probe signal, pr2 is the first signal strength, pr3 is the second signal strength, and a is the polarization difference between the second ultra-wideband antenna and the third ultra-wideband antenna.

Note that a is a constant that can be adjusted. In the UWB system shown in fig. 2, ANT2 and ANT3 are polarized differently by 90 °, so that a cannot be easily compared, and therefore a is introduced to consider the difference in polarization of ANT2 and ANT 3.

Exemplarily, as shown in fig. 3, it is assumed that the data antennas are disposed at the upper and right sides of the electronic device, the ultra-wideband antenna ANT2 is located at the upper side of the electronic device, and the ultra-wideband antenna ANT3 is located at the left side of the electronic device. Then, when the screen of the electronic device faces the head of the human body, the intensity of the reflected signal received by the ANT2 is Pr2, and the intensity of the reflected signal received by the ANT3 is Pr3; when P1-Pr2< a × (P1-Pr 3), the ANT2 is considered to be closer to the human body, and it is determined that the data antenna located on the upper side of the electronic device is closer to the human body, and when P1-Pr2 > a × (P1-Pr 3), the ANT3 is considered to be closer to the human body, and it is determined that the antenna located on the right side portion of the electronic device is closer to the human body.

In the above embodiment, the UWB can acquire the intensity of the reflected signal in the normal working process, and therefore, the SAR detection can be performed without occupying more resources by adding software logic, so as to obtain the relative distance and the relative position between the electronic device and the human body, avoid the occupation of the space of the electronic device by the arrangement of the SAR sensor, reduce the cost of the arrangement of the SAR sensor, and do not affect the normal working of the UWB system.

Further, the adjusting the maximum transmitting power of the target antenna according to the position information includes:

when the first position of the electronic equipment is determined to be close to the human body, reducing the maximum transmitting power of a target antenna close to the first position; alternatively, the first and second electrodes may be,

when the second position of the electronic equipment is determined to be close to the human body, reducing the maximum transmitting power of the target antenna close to the second position.

During specific implementation, the maximum transmitting power of the data antenna close to the human body can be adjusted to be a first value, and the transmitting power of the data antenna far away from the human body is adjusted to be a second value; wherein the first value is less than the second value. Thus, the radiation performance of the data antenna far away from the human body can be ensured to the maximum extent.

In specific implementation, when the target antenna is detected to be closer to the human body, the maximum transmitting power of the target antenna can be reduced, and the maximum transmitting power of the data antenna far away from the human body can be increased. Therefore, the communication performance of the electronic equipment can be better ensured.

A specific example of the method for adjusting the antenna transmission power according to the present application is described below with reference to fig. 5.

As shown in fig. 5, the method for adjusting the antenna transmission power specifically includes the following steps:

and step 51, acquiring the corresponding relation between the attenuation value and the reflection distance of the signal after reflection through training.

Step 52, detecting whether the receiver works; if yes, performing step 3; if not, continuing the detection.

In step 53, the ANT1 sends a probe sequence with specific signal strength P1 for SAR detection, and simultaneously receives the reflected signals of the probe sequence through the ANT2 and the ANT3, respectively, and detects the signal strengths Pr2 and Pr3 of the reflected signals.

Step 54, judging whether the attenuation value of the reflected signal is smaller than a threshold value; if so, step 55 is performed, otherwise step 52 is performed.

That is, it is determined whether: P1-Pr2 is less than or equal to delta P12, and P1-Pr3 is less than or equal to delta P13.Δ P12 and Δ P13 are thresholds.

Step 55, judging whether: P1-Pr2< a × (P1-Pr 3), or, P1-Pr2 > a × (P1-Pr 3); if yes, go to step 56; if not, go to step 55.

Step 56, the maximum transmit power of the target antenna is reduced.

The SAR detection is carried out in the above example by testing the intensity of the reflected signal, the SAR sensor can be replaced, the space occupation of the SAR sensor is reduced, the cost is saved, and the normal work of the UWB is not influenced.
