Fig. 3 is a schematic network architecture diagram illustrating a positioning method applicable to the present application, and as shown in fig. 3, the schematic network architecture diagram includes a plurality of electronic devices, which may include: the electronic device includes, but is not limited to, a first device (the electronic device 100a) and a plurality of second devices (the electronic device 200a, the electronic device 200b, and the electronic device 200c), where the electronic devices may be a smart phone, a tablet computer, a desktop computer, a wearable electronic device with a wireless communication function, and the electronic devices may be the electronic device 100 shown in fig. 1.

Of course, each second device can also communicate with each other to achieve positioning.

For example, the electronic device 100a (the first device) may determine, through the bluetooth module, a target distance to a second device (the electronic device 200a, the electronic device 200b, or the electronic device 200c) within a preset range, where the target distance is determined according to a Beacon signal corresponding to the second device, and the Beacon signal is obtained by the bluetooth module sending a BLE signal and scanning at preset time intervals; if the target distance is smaller than or equal to the first threshold value, starting the UWB communication module, and completing positioning the second equipment through the UWB communication module; if the target distance is greater than the first threshold and smaller than a second threshold, starting the UWB communication module and the preset positioning module, and positioning the second device through the UWB communication module and the preset positioning module, wherein the second threshold is greater than the first threshold; if the target distance is greater than or equal to the second threshold, starting a preset positioning module, and positioning the second device through the Bluetooth module preset positioning module; so, can be based on the distance between equipment, the different locate mode of reasonable adoption is different from traditional single locate mode, combines bluetooth module, UWB communication module and predetermines the locate module and uses, is favorable to improving the location distance, is favorable to improving positioning accuracy, simultaneously, also can satisfy user's different location demands, is favorable to improving user experience.

In the third section, the scope of protection of the claims disclosed in the embodiments of the present application is described below.

Referring to fig. 4, fig. 4 is a flowchart illustrating a positioning method according to an embodiment of the present application, applied to a first device, where the first device includes a bluetooth module, a UWB communication module, and a preset positioning module.

S401, determining a target distance between second equipment in a preset range through the Bluetooth module, wherein the target distance is determined according to a Beacon signal corresponding to the second equipment, and the Beacon signal is obtained by scanning a BLE signal sent by the Bluetooth module at preset time intervals.

In the embodiment of the present application, the preset positioning module may include an auxiliary positioning technology, where the auxiliary positioning technology may refer to a non-communication positioning mode, for example, the auxiliary positioning may be performed in an inertial navigation mode, and the principle is that sensors such as a gyroscope and an accelerometer are used to measure angular velocity and acceleration integral of a carrier, and speed and position information of other devices are obtained through integral operation.

The preset time interval may be set by a user or default to a system, and is not limited herein, the preset time interval may be 0.5s, 1s, 3s, 1min, 10min, and the like, and the first device may send a BLE signal through the bluetooth module at intervals of the preset time interval, so as to detect and obtain a Beacon signal sent by another device.

The preset range can be set by a user or defaulted by a system, and is not limited herein; in this embodiment of the present application, the preset range may refer to a signal area corresponding to a Beacon signal sent by the second device.

When the UWB communication module is used to realize the positioning of the second device, since FCC (federal communications commission) regulations limit that the emission power spectral density of the UWB signal sent by the UWB communication module needs to be less than-43.3 dBm/MHz, and the highest emission power of the UWB signal does not exceed-41.3 dBm/MHz for a long-distance communication distance, as a result, when the distance between the devices is long, the positioning using the UWB technology limits the increase of the positioning distance, which may affect the positioning accuracy.

In specific implementation, the second device may include Beacon devices, the Beacon devices may be mounted in a bluetooth module, a Beacon signal transmitting base station may be constructed through the bluetooth module, and Beacon signals may be sent to the surroundings in a broadcast manner, so that a signal area may be created.

Furthermore, the first device may include a bluetooth module, and after the first device starts the positioning function, the first device may send BLE signals through the bluetooth module, and after the first device enters the Beacon signal area established by the second device through the bluetooth module, the first device may scan through the bluetooth module to obtain Beacon signals sent by the second device, so that the target distance between the first device and the second device may be determined through the signal strength of the received Beacon signals.

It can be seen that, in this embodiment of the present application, a target distance between a first device and a second device within a preset range may be determined by combining a bluetooth module with a Beacon technology, and as an ISM2.4G frequency band is generally used for sending a BLE signal by the bluetooth module, the frequency is lower, and a very fast communication connection may be provided by using the BLE technology, when positioning is required, a BLE signal may be sent to a peripheral device, and a communication link may be established, and when positioning is not required, a communication link with the second device may be quickly cut off, so that the bluetooth module is used to send the BLE signal to the periphery, which is beneficial to reducing power consumption of the device.

In a possible example, the determining of the target distance according to the Beacon signal corresponding to the second device may include: determining the signal intensity corresponding to the Beacon signal received by the first device according to the Beacon signal; determining a target free space loss value corresponding to the signal intensity according to a mapping relation between preset signal intensity and the free space loss value; and determining a target distance corresponding to the target free space loss value according to a mapping relation between a preset distance and the free space loss value.

Wherein, because the signal strength of the signal is attenuated during the transmission process, the first device may preset a mapping relation between the signal strength and a loss value of a free space before determining the target distance between the devices:

P_RSSI＝P_TX-L_S；

where PRSSI denotes received signal strength, and PTX denotes power of a transmitting end.

Therefore, the target free space loss value corresponding to the signal intensity can be determined according to the signal intensity corresponding to the Beacon signal, and the free space loss value can be determined according to the free space loss value.

Further, since the signal is attenuated during transmission due to the distance between the devices, the first device may preset a mapping relationship between the distance between the two devices and the free space loss value, where the mapping relationship may be set as:

L_S＝32.45+20log₁₀(f_MHz)+20log₁₀(D_Km)

wherein LS represents a free space loss value (dB), fMHz represents an operating frequency, and DKm represents a distance;

thus, a target distance between the first device and the second device may be determined from the obtained target free space loss value.

S402, if the target distance is smaller than or equal to a first threshold value, starting the UWB communication module, and completing positioning of the second device through the UWB communication module.

The first threshold may be set by the user or default by the system, and is not limited herein; the above-mentioned first threshold value, which can be applied to the UWB communication module, can be understood as the maximum distance that the first device can bear when the UWB communication module is used to perform device positioning, under the condition that the above-mentioned transmission power is satisfied.

When the UWB communication module is used to position the second device, a TOF time of flight mode may be used, as shown in fig. 4B, which is an interaction diagram between the first device and the second device; when obtaining the distance information, the first device sends a request carrying time stamp information to the second device, and the second device receives the request and adds its own time stamp information to send back to the first device, so that the distance between the second device and the first device can be obtained by ((first device receiving time T3-first device sending time T0) - (second device sending time T2-second device receiving time T1))/2, which is called time of flight (TOF). After the flight time is obtained, the distance between the first equipment and the second equipment can be obtained according to the propagation speed c TOF of the electromagnetic wave: distance TOF (T3-T0) - (T2-T1))/2.

It can be seen that, in the embodiment of the present application, when the target distance is less than or equal to the first threshold, it indicates that the UWB communication technology can be used to position the second device, the UWB communication module may be started, and the UWB communication module is used to realize the positioning of the second device, so, after the bluetooth module is used to determine the target distance between the two devices, if the target distance is less than or equal to the first threshold, it indicates that the UWB communication module is used to realize the more accurate positioning of the second device, and the target distance is within the distance threshold corresponding to the optimal accuracy of the UWB positioning technology, and the UWB communication module, that is, the UWB positioning technology can be used to realize the positioning of the second device, so that a more accurate positioning result can be obtained, which is beneficial to saving the power consumption of the device.

And S403, if the target distance is greater than the first threshold and smaller than a second threshold, starting the UWB communication module and the preset positioning module, and positioning the second device through the UWB communication module and the preset positioning module, wherein the second threshold is greater than the first threshold.

The second threshold may be set by the user or default by the system, and is not limited herein; the second threshold value may be understood as the maximum distance over which the UWB communication module can emit UWB signals, and is greater than the first threshold value.

Wherein, because FCC (Federal communications Commission) regulations limit UWB communication module to send UWB signal emission power spectral density need less than-43.3 dBm/MHz, and the highest emission power must not exceed-41.3 dBm/MHz for long-distance communication distance, thus, if positioning by UWB technology limits increase of positioning distance, and no matter positioning the second equipment by the above Bluetooth module or positioning the second equipment by UWB communication module, its positioning accuracy in large angle area will be deteriorated, reflecting that positioning distance will be shortened, therefore, when the distance between the first equipment and the second equipment is greater than the first threshold value and less than the second threshold value, at this time, if positioning the second equipment by UWB communication module only, it may affect its positioning accuracy, causing its positioning accuracy error to be larger, therefore, the preset positioning module and the UWB communication module can be combined for use, the second equipment is positioned through the UWB communication module, and meanwhile, the positioning result of the UWB communication module is corrected through the preset positioning module, so that the positioning precision is improved.

In one possible example, the positioning of the second device by the UWB communication module and the preset positioning module may include: acquiring position information corresponding to the second equipment at a plurality of first preset moments through the UWB communication module to obtain a plurality of first position information; determining, by the preset positioning module, position information corresponding to the second device at the plurality of first preset moments to obtain a plurality of second position information; and correcting the plurality of first position information and the plurality of second position information according to a preset position correction mode to obtain a plurality of first target position information so as to complete the positioning of the second equipment.

The preset position correction mode can be set by a user or defaulted by a system, and is not limited herein; the position information determined by the UWB communication module may be modified by a preset position modification manner to complete the positioning of the second device.

Wherein, the position information may include at least one of the following: device distance, angle information, etc., without limitation.

The first preset time can be set by a user or defaulted by a system, and is not limited herein; the UWB signal may be transmitted through the UWB communication module at the first preset time to determine the location information of the second device, so as to obtain a plurality of first location information.

Furthermore, when the UWB communication module collects the location information of the second device at a plurality of first preset times, the location information corresponding to each of the first preset times at the plurality of first preset times can be determined through the preset location module to obtain a plurality of second location information, and then the plurality of first location information can be corrected or revised according to a preset location revision mode in combination with the plurality of first location information and the plurality of second location information to determine a plurality of first target location information, so as to complete the location of the second device.

It can be seen that, in this embodiment of the present application, when the target distance is greater than the first threshold and less than the second threshold, because if the second device is located only through the UWB communication module, the target distance between the two devices is far away at this time, the location accuracy of the UWB communication module may be affected, and the location accuracy is reduced, so in this embodiment of the present application, the location result of the UWB communication module may be corrected by presetting the location module, which is beneficial to improving the location accuracy, and meanwhile, the problem of limitation of the communication distance is avoided, which leads to the situation of inaccurate location, and is beneficial to reducing the influence of the increase of the communication distance on location.

In a possible embodiment, the correcting the plurality of first location information and the plurality of second location information according to a preset location correction manner to obtain a plurality of first target location information may include: and determining a median value between the first position information and the second position information corresponding to each first preset moment as target position information according to the preset position correction mode, so as to obtain the plurality of first target position information.

For example, the intermediate value between the first position information Sn _ U and the second position information Sn _ I may be the first target position information, or may be determined according to another ratio or a formula (Sn _ I + Sn _ U)/I, where I is a positive number.

In a possible example, the determining the location information corresponding to the second device at a plurality of first preset times to obtain a plurality of second location information may include: obtaining an initial position, the initial position being determined by the UWB communication module; obtaining angle information measured at each first preset moment to obtain a plurality of angle information; obtaining distance information between a position corresponding to each first preset moment and the initial position to obtain a plurality of distance information; and determining the position information corresponding to each first preset moment according to the angle information and the distance information to obtain a plurality of second position information.

Wherein the initial position S₀(E₀，N₀) The relative position information reported by the UWB when the positioning precision is higher.

In a specific implementation, as shown in fig. 4C, the motion trajectory diagram is a motion trajectory diagram corresponding to a preset positioning module, specifically, the motion trajectory diagram is a motion trajectory diagram between a first device and a second device corresponding to a plurality of first preset moments acquired by the preset positioning module, and the motion trajectory diagram is located at a known initial position S₀(E₀，N₀) On the basis, the gyroscope is used for obtaining angle information measured at each first preset moment to obtain a plurality of angle information theta_nObtaining distance information d using an acceleration sensor and a timer_nThen, combining the preset formula shown below and a plurality of angle information and distance information, the second position information at any time can be calculated: sn _ I (E)_k，N_k) Wherein n is a positive integer, and the predetermined formula is:

thereby obtaining the motion trail generated by the preset positioning module at a plurality of first preset moments.

Further, as shown in fig. 4D, which is an interaction diagram between a first device and a second device, different antennas of the first device receive signals transmitted from the same antenna of the second device, and a phase difference is generated due to different phases of the same signal reaching different antennas. The phase difference to the different antennas of the first device may then be based on

The wavelength λ of the signal and the distance d between different antennas of the first device calculate the angle information θ of the second device relative to the first device, specifically by the following formula:

thus, the angle information measured at each first preset time is obtained, and a plurality of angle information theta are obtained_nTherefore, the distance information corresponding to the second device at a plurality of first preset moments can be obtained through the UWB communication module, so that a plurality of first position information Sn _ U can be obtained, and the specific distance obtaining manner is as described above and is not repeated herein, so that the motion trajectory corresponding to the UWB communication module can be obtained.

As shown in fig. 4E, a motion trajectory diagram may include a motion trajectory Sn _ U corresponding to a motion trajectory Sn _ I, UWB corresponding to a preset positioning module, and a target motion trajectory Sn composed of a plurality of first target location information, and further, the first device may determine the plurality of first target location information by determining an intermediate value between the first location information and the second location information corresponding to each first preset time as the target location information through a preset location correction manner, that is, the target location information Sn is (Sn _ I + Sn _ U)/2, and a trajectory composed of the plurality of first target location information is the target motion trajectory Sn, thereby positioning the second device.

S404, if the target distance is larger than or equal to the second threshold value, starting the preset positioning module, and positioning the second device through the Bluetooth module and the preset positioning module.

Wherein, because when the target distance between the equipment is extremely far away, the signal receives the influence of multipath and signal attenuation in the transmission process, it is great to lead to UWB positioning accuracy error through UWB communication module, it is possible not to receive the UWB signal that the second equipment sent even, therefore, this moment, can not adopt UWB communication module to realize the location to the second equipment, in order not to break off the location to the second equipment, can continue to pass through bluetooth module under the condition to the second equipment location, accomplish the accurate positioning to the second equipment through predetermineeing the orientation module, thus, be favorable to guaranteeing not to break off the location to the second equipment, and be favorable to improving the positioning distance between the equipment by a wide margin, thereby improve user experience.

In a possible example, the positioning of the second device by the bluetooth module and the preset positioning module may include the following steps: acquiring position information corresponding to the second equipment at a plurality of second preset moments through the Bluetooth module to obtain a plurality of third position information; determining, by the preset positioning module, position information corresponding to the second device at the second preset times to obtain fourth position information; and determining a middle value between the third position information and the fourth position information corresponding to each second preset moment as target position information to obtain a plurality of second target position information so as to complete the positioning of the second equipment.

The second preset time can be set by the user or defaulted by the system, and is not limited herein; the second preset moments can be different, and the distance information and the angle information between the second equipment and the first equipment at each second preset moment can be determined through the Bluetooth module, so that the position information corresponding to the second equipment at the second preset moments is obtained, and a plurality of third position information is obtained; the method for determining the angle information between the second device and the first device is the same as the angle measurement method shown in fig. 4D, and is not described herein again, and the distance information between the first device and the second device may be determined according to the mapping relationship between the preset signal strength and the free space loss value and the mapping relationship between the preset distance and the free space loss value, and is not described herein again.

Further, the position information of the second device corresponding to a plurality of second preset moments is determined through a preset positioning module, so as to obtain a plurality of fourth position information, wherein the fourth position information includes distance information and angle information, and the specific determination mode is the same as the mode for determining the first position information, and is not repeated here.

Finally, a plurality of second target position information can be obtained by determining a median value between the third position information Sn _ B and the fourth position information Sn _ U corresponding to the same second preset time as the target position information, and of course, the second target position information can also be determined by a formula (Sn _ I + Sn _ U)/j, where j is a positive number.

Optionally, the method may further include the steps of: acquiring a current use environment; and if the current use environment meets a preset condition, positioning the second equipment through the preset positioning module.

The preset condition can be set by the user or defaulted by the system, and is not limited herein; for example, the preset condition may refer to a case where communication is interrupted.

The current usage environment may be a current communication environment, and if the current usage environment is in an elevator or a closed dense crowd environment, a communication interruption may occur, and at this time, the bluetooth module or the UWB communication module are both usedIf the second device cannot be used, the preset positioning module is a non-communication positioning mode without establishing a communication link with the second device, and the preset positioning module can be independently adopted to complete the positioning of the second device; the specific implementation manner is the same as the above-mentioned manner of positioning the second device by the preset positioning module, except that the initial position E is the current position₀And final position information for positioning the UWB communication module or the Bluetooth module before the communication interruption.

Therefore, in the embodiment of the application, in a special environment, if communication is interrupted, the positioning can be achieved independently by means of the preset positioning module, namely, the positioning is achieved through inertial navigation assistance, the positioning distance between devices is further increased, and the improvement of user experience is facilitated.
