Detailed ways

The following will clearly describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in this application belong to the protection scope of this application.

The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific sequence or sequence. It should be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application can be practiced in sequences other than those illustrated or described herein, and that references to "first," "second," etc. distinguish Objects are generally of one type, and the number of objects is not limited. For example, there may be one or more first objects. In addition, "and/or" in the description and claims means at least one of the connected objects, and the character "/" generally means that the related objects before and after are an "or" relationship.

The working principle of UWB indoor positioning technology is to arrange multiple UWB positioning base stations with known coordinates indoors. The equipment to be positioned carries UWB tags. UWB tags can transmit pulse signals according to a certain frequency, and use different UWB positioning base stations to receive UWB tags. The time difference of the sent pulse signal determines the position of the device to be positioned.

Based on the working principle of UWB indoor positioning technology, UWB positioning technology can be applied to handheld devices to find objects. The handheld device may be, for example, a mobile phone, a tablet computer, a wearable device, and the like. Specifically, at least two UWB antennas are set in the handheld device. The object to be searched, that is, the target device, carries a UWB tag, and the UWB tag can transmit pulse signals at a certain frequency, and the UWB tag can be received by different UWB antennas in the handheld device. The time difference of the pulse signal sent out realizes the positioning of the target device. However, due to the limited thickness of the handheld device, the number of UWB antennas arranged is limited, which affects the positioning accuracy.

In the related art, as shown in Figure 1, UWB dual antennas are set on the same reference plane of the handheld device, for example, a pair of UWB antennas (UWB antenna 1 and UWB antenna 2) are set on the plane perpendicular to the ground between the handheld device and the UWB antenna. The UWB antenna pair can measure the distance and angle between the target device and the baseline of the UWB antenna pair, so as to determine the position of the target device. However, the same measurement result will correspond to multiple target orientations. The baseline of the antenna pair is two symmetrical mirror positions, that is to say, for this method, the actual position of the target device cannot be distinguished during the measurement process, and the target device cannot be accurately located.

In the related art, as shown in Figure 2, the UWB antenna array is set on the same reference plane of the handheld device, for example, three UWB antennas (UWB antenna 1, UWB antenna 2 and UWB antenna 3 are set on the plane perpendicular to the ground of the handheld device) ), the UWB antenna array can be used to measure the distance and angle between the target device and the baseline of the UWB antenna pair, so as to determine the position of the target device. However, the same measurement result will correspond to two target orientations, that is, the The two target azimuths with the plane where the antenna array is located as a mirror image, that is to say, for this method, the actual position of the target device cannot be distinguished during the measurement process, and the target device cannot be accurately located.

In order to solve the above-mentioned problem of poor positioning accuracy due to the limited thickness of the handheld device (for example, a mobile phone), the number of antennas installed is limited, the embodiment of the present application provides a positioning method, which transmits the target object according to at least two antennas. The first signal of the target object is used to determine the orientation information of the target object relative to the electronic device, that is, to determine whether the target object is located on the front or back of the electronic device, so as to achieve precise positioning of the target device.

The positioning method provided by the embodiment of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

Please refer to FIG. 3 , which is a flow chart of a positioning method provided in an embodiment of the present application. The method can be applied to an electronic device, and the electronic device can be the handheld device in the foregoing embodiments, and the electronic device can be a mobile phone, a tablet computer, a notebook computer, and the like.

As shown in FIG. 3, the method may include steps 3100-3200, which will be described in detail below.

Step 3100: Receive the first signal transmitted by the target object through the at least two antennas respectively.

The electronic device is provided with at least two antennas, and the at least two antennas are arranged on the first side. The electronic device is applied to the scene where a handheld electronic device searches for an item. When the electronic device is used to find an item, the screen of the electronic device faces the user, and the back shell of the electronic device faces the item to be found, that is, the back shell of the electronic device points to the item to be found. The area to look for. Based on this, in order to facilitate the use of the electronic device to find items, the first side may be the side opposite to the screen of the electronic device. Exemplarily, the first side may be the back shell of the electronic device, that is to say, at least two antennas may be disposed on the back shell of the electronic device. Exemplarily, the first side may also be a side close to the back shell of the electronic device.

In this embodiment, the antenna provided on the electronic device is an ultra-wideband antenna (UWB antenna). The number of antennas provided on the electronic device can be set according to actual conditions. For example, as shown in FIG. 1, the electronic device may be provided with two antennas (UWB antenna 1 and UWB antenna 2). Also for example, as shown in FIG. 2, the electronic device may also be provided with three antennas, specifically including UWB antenna 1, UWB antenna 2, and UWB antenna 3, wherein UWB antenna 1 and UWB antenna 2 are arranged along the X direction, and UWB antenna 1 and the UWB antenna 3 are arranged along the Y direction.

The target object is an object to be located. The target object is used to transmit a signal to the electronic device, so that the electronic device locates the target object.

In some embodiments, the target object is provided with an ultra-wideband module, that is, the target object is provided with a UWB tag. The target object transmits a first signal at a predetermined frequency through the ultra-wideband module. In a specific implementation, receiving the first signal transmitted by the target object through at least two antennas respectively includes: receiving the first signal transmitted by the ultra-wideband module of the target object at a predetermined frequency through at least two antennas respectively.

Step 3200: Determine the orientation information of the target object relative to the electronic device according to the first signals received by the at least two antennas.

In this embodiment, the orientation information of the target object relative to the electronic device is used to indicate the relative positional relationship between the target object and the electronic device, and the position of the target object can be accurately indicated after the orientation information of the target object relative to the electronic device is determined.

Specifically, when using an electronic device to find a target object, the user holds the electronic device, the front of the electronic device faces the user, and the back of the electronic device faces outward, that is, the plane of the electronic device for installing at least two antennas faces outward. When the target object is located at the back of the electronic device, the target object is away from the screen of the electronic device, that is, when the electronic device is used to locate the target object, the target object is located in front of the user. When the target object is located in front of the electronic device, the target object is facing the screen of the electronic device, that is, when the electronic device is used to locate the target object, the target object is located behind the user.

In the process of using the electronic device to find the target object, when the target object is located at the back of the electronic device, that is, when the target object is located in front of the user, the position of the target object can be indicated to the user according to the measured position information. When the target object is located in front of the electronic device, that is, when the target object is located behind the user, the position of the target object cannot be correctly indicated according to the measured position information. Based on this, before indicating the position of the target object, it is necessary to first determine the orientation information of the target object relative to the electronic device.

Furthermore, since the electronic device has a certain thickness, and the target object is located on the back and the front of the electronic device, the propagation paths of the first signal emitted by the target object to the electronic device are different, and the first signal received by at least two antennas of the electronic device The first received signal strengths of the signals are also different. Based on this, the orientation information of the target object relative to the electronic device can be determined according to the first signals received by at least two antennas, and after the orientation information of the target object relative to the electronic device is determined, the position of the target object can be accurately indicated.

Exemplarily, determining the orientation information of the target object relative to the electronic device according to the first signals received by at least two antennas may be: when at least two antennas receive the first signal transmitted by the target object at the current moment, according to The time difference between at least two antennas receiving the first signal determines the orientation information of the target object relative to the electronic device. When the at least two antennas receive the first signal transmitted by the target object at the next moment, the position information of the target object relative to the electronic device is determined again according to the time difference between the at least two antennas receiving the first signal, so as to realize the target object. Real-time positioning.

In this embodiment, determining the orientation information of the target object relative to the electronic device according to the first signals received by at least two antennas may be determined according to the first received signal strength of the first signals received by at least two antennas. The orientation information of the target object relative to the electronic device. Determine the orientation information of the target object relative to the electronic device according to the first signals received by at least two antennas, or obtain the distance change rate between the target object and the electronic device according to the first signals received by at least two antennas , according to the rate of change of the distance between the target object and the electronic device, determine the orientation information of the target object relative to the electronic device. The two methods will be described respectively below with specific embodiments.

In some embodiments of the present application, the determining the orientation information of the target object relative to the electronic device according to the first signals received by the at least two antennas may further include: step 4100-step 4300.

Step 4100, acquire a first received signal strength of the first signal.

Wherein, the first received signal strength is jointly determined according to the received signal strengths of the first signals received by the at least two antennas.

The magnitude of the first received signal strength may reflect the distance between the target object and the electronic device. For example, please refer to FIG. 4 , which is a relationship curve between the first received signal strength and the distance between the target object and the electronic device. As shown in FIG. 4 , as the distance between the target object and the electronic device increases, the first received signal strength of the first signal becomes smaller.

In this embodiment, taking at least two antennas arranged on the back shell of the electronic device as an example, when the target object is located on the back of the electronic device, that is, the target object is located in front of the user, at this time, as the target object and As the distance between the electronic devices increases, the strength of the first received signal decreases accordingly. When the target object is located in front of the electronic device, that is, the target object is located behind the user, since the electronic device has a certain thickness, the first signal emitted by the target object is blocked by the device body of the electronic device, resulting in the first received signal strength severe attenuation, the first received signal strength of the first signal received by the electronic device is greatly reduced. That is to say, the strength of the first received signal may also reflect whether the first signal transmitted by the target object is blocked. Based on this, the orientation information of the target object relative to the electronic device may be determined according to the first received signal strength.

In case the electronic device includes at least two antennas, the distances between the at least two antennas and the target object are substantially equal. Based on this, for example, acquiring the first received signal strength of the first signal received by the antenna of the electronic device may further include: receiving the first signal received by any one of the at least two antennas The signal strength is used as the first received signal strength. Exemplarily, obtaining the first received signal strength of the first signal received by the antenna of the electronic device may further include: taking the average value of the received signal strength of the first signal received by the at least two antennas as the obtained The first received signal strength.

In this embodiment, the average value of the received signal strengths of the first signals received by at least two antennas is used as the first received signal strength, which can improve detection accuracy, thereby improving positioning accuracy.

After step 4100, step 4200 is executed to determine that the target object is located in front of the electronic device when the first received signal strength is much smaller than the second received signal strength.

Step 4300, except that the first received signal strength is much smaller than the second received signal strength, determine that the target object is located at the back of the electronic device.

It can be understood that the case that the first received signal strength is much smaller than the second received signal strength may be the case that the first received signal strength is relatively close to the second received signal strength. For example, the first received signal strength is equal to the second received signal strength. Also for example, the first received signal strength is slightly smaller than the second received signal strength.

The second received signal strength is related to the distance of the target object from the electronic device. The second received signal strength is a theoretical value of the received signal strength of the first signal received by the antenna of the electronic device when the distance between the target object and the electronic device is constant.

In this embodiment, it may be determined whether the first received signal strength is much smaller than the second received signal strength according to the difference between the second received signal strength and the first received signal strength.

Exemplarily, in the case where the difference between the second received signal strength and the first received signal strength is greater than or equal to a second threshold, it is determined that the first received signal strength is much smaller than the second received signal strength; If the difference of the first received signal strength is smaller than the second threshold, it is determined that the first received signal strength is relatively close to the second received signal strength.

The second threshold may be used to measure whether the first received signal strength is much smaller than the second received signal strength. The second threshold can be set by those skilled in the art according to the simulation test results, which is not specifically limited in this embodiment of the present application.

Continuing to take at least two antennas arranged on the back shell of the electronic device as an example, in the case where the first received signal strength is much smaller than the second received signal strength, that is, the difference between the second received signal strength and the first received signal strength If the difference is greater than the second threshold, it means that the first signal emitted by the target object is blocked by the device body of the electronic device, which causes serious attenuation of the strength of the first received signal, that is, the target object is located in front of the electronic device, and the target object towards the screen of an electronic device.

If the first received signal strength is much lower than the second received signal strength, that is, if the first received signal strength is close to the second received signal strength, it means that there is no occlusion between the target object and the electronic device , the target object is located in front of the electronic device, that is, the target object is located at the back of the electronic device, and the target object faces away from the screen of the electronic device.

In this embodiment, during the process of using the electronic device to find the item, the first received signal strength of the first signal received by the antenna of the electronic device is measured in real time, and the first received signal strength is compared with the theoretically calculated second received signal By comparing the intensity, it is possible to distinguish whether the target object is located on the front or the back of the electronic device, thereby improving the accuracy of locating the target object.

In some embodiments of the present application, before obtaining the first received signal strength of the first signal, the positioning method may further include: Step 5100-Step 5200.

Step 5100: Obtain the distance between the target object and the electronic device according to the first signals received by the at least two antennas.

During specific implementation, the distance between the target object and the electronic device may be determined according to the time difference between at least two antennas receiving the first signal.

Step 5200: Determine a second received signal strength according to the distance between the target object and the electronic device.

Exemplarily, the second received signal strength can be obtained by the following formulas (1) and (2):

RSSI ₂ = txPower+pathloss+rxGain+SystemGain (1)

Among them, RSSI ₂ is the second received signal strength, txPower is the transmitted power of the first signal, pathloss is the path attenuation of the first signal, rxGain is the receiving gain of the antenna of the electronic device receiving the first signal, and SystemGain is the receiving gain of the antenna of the electronic device The system gain of the first signal. Among them, txPower, rxGain, and SystemGain are fixed values. Pathloss is related to the propagation distance of the first signal.

pathloss＝36.6+(20log10(f))+(20log10(D)) (2)

Wherein, D is the distance between the target object and the electronic device.

In this embodiment, the second received signal strength is determined according to the distance between the target object and the electronic device, and the real-time measured first received signal strength of the first signal is compared with the theoretically calculated second received signal strength, which can be It is distinguished whether the target object is located on the front or the back of the electronic device, so that the accuracy of locating the target object can be improved.

In some other embodiments of the present application, the determining the orientation information of the target object relative to the electronic device according to the first signals received by the at least two antennas may further include: Step 6100- Step 6300.

Step 6100: Obtain the rate of change of the distance between the target object and the electronic device according to the first signals received by the at least two antennas.

In this embodiment, please refer to FIGS. 5 and 6. FIG. 5 is a schematic diagram of a propagation path of a first signal according to an embodiment of the present application, and FIG. 6 is a distance between a target object and an electronic device according to an embodiment of this application. A schematic diagram of the measurement results. Specifically, continuing to take at least two antennas arranged on the back shell of the electronic device as an example, when the target object is located at the back of the electronic device, that is, the target object is located in front of the electronic device, the first signal emitted by the target object may be The antenna of the electronic device is reached through a direct path (path 1). At this time, the variation range of the distance between the measured target object and the electronic device is small, and the multiple measurement results can be shown in FIG. 6 .

When the target object is located in front of the electronic device, that is, the target object is located behind the electronic device, the first signal emitted by the target object is blocked by the device body of the electronic device and cannot be directly transmitted to the electronic device, but reaches the electronic device after reflection. equipment. Since there may be multiple reflection paths, such as path 2 and path 3 shown in the figure, in this way, the measured distance between the target object and the electronic device is different when reaching the electronic device through different reflection paths. At this time, The distance between the measured target object and the electronic device varies greatly, and the measurement result is unstable, as shown in FIG. 6 for multiple measurement results.

Based on this, the distance change rate between the target object and the electronic device is obtained according to the first signals received by at least two antennas, and the orientation information of the target object relative to the electronic device can be determined.

In this embodiment, the target object transmits the first signal with a predetermined frequency, and at least two antennas of the electronic device receive the target object transmits the first signal with the predetermined frequency. When at least two antennas of the electronic device receive the first signal, the distance between the target object and the electronic device can be determined according to the time difference of the first signal received by the at least two antennas, that is, multiple measurements can be obtained result.

The rate of change of the distance between the target object and the electronic device may be determined according to the distances between the target object and the electronic device measured twice adjacently.

Exemplarily, the rate of change of the distance between the target object and the electronic device can be obtained by the following formula (3):

v=(D ₂ −D ₁ )/t (3)

Among them, v is the rate of change of the distance between the target object and the electronic device, D ₁ is the distance between the target object and the electronic device measured at the current moment, and D ₂ is the distance between the target object and the electronic device measured at the next moment , t is the time interval between two measurements of the distance between the target object and the electronic device, that is, the time interval between the electronic device receiving the first signal twice.

It should be noted that the rate of change of the distance between the target object and the electronic device may also be determined according to the slope of the distance change curve between the target object and the electronic device.

Step 6200, if the rate of change of the distance is less than or equal to a first threshold, determine that the target object is located at the back of the electronic device.

Step 6300, if the rate of change of the distance is greater than the first threshold, determine that the target object is located in front of the electronic device.

The first threshold is used to measure whether the rate of change of the distance between the target object and the electronic device is too large.

In some embodiments, when the user uses the electronic device to find the target object, the distance between the target object and the electronic device will change as the user moves, that is, the distance change rate between the target object and the electronic device is related to the user's movement. The speed is the same. Based on this, the first threshold may be set according to the speed at which the user moves indoors. Exemplarily, the first threshold may be an average moving speed of the user, for example, 2m/s, which is not limited in this embodiment of the present application.

In this embodiment, in the case that the rate of change of the distance between the target object and the electronic device is less than or equal to the first threshold value, it means that the fluctuation of the distance between the target object and the electronic device obtained through multiple measurements is small, and the target object can be determined Located on the back of the electronic device, that is, the target object is located in front of the electronic device, and the target object faces away from the screen of the electronic device. If the rate of change of the distance between the target object and the electronic device is greater than the first threshold, it indicates that the distance between the target object and the electronic device fluctuates greatly from multiple measurements, and it can be determined that the target object is located in front of the electronic device, that is, the target The object is located behind the electronic device, and the target object faces the screen of the electronic device.

In this embodiment, in the process of using the electronic device to find items, the rate of change of the distance between the target object and the electronic device is obtained through multiple measurements, and it can be distinguished whether the target object is located on the front or the back of the electronic device, thereby improving the accuracy of the positioning target. object accuracy.

In some embodiments of the present application, after determining the orientation information of the target object relative to the electronic device according to the first signals received by the at least two antennas, the positioning method may further include: step 7100 - Step 7200.

Step 7100, if it is determined that the target object is located on the back of the electronic device, according to the first signal received by the at least two antennas, obtain the azimuth angle of the target object relative to the electronic device and the distance between the target object and the electronic device.

Step 7200, display the azimuth and the distance.

In this embodiment, in the process of using the electronic device to find items, after determining whether the target object is located on the front or the back of the electronic device, based on the measured distance and azimuth of the target object relative to the electronic device, the target object and displaying the azimuth and distance of the target object relative to the electronic device on the electronic device can instruct the user to find the target object.
