[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0046] In this application, the relationship terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations, the term "comprising", "containing" or any other variant thereof is intended to cover non-exclusive containing, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitations, the element defined by the statement "including a" does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0047] The present application can be used in many general or special-purpose computing device environments or configurations. For example: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor devices, distributed computing environments that include any of the above devices or devices, etc.

[0048] The communication positioning device provided by the embodiments of the present application has a structure diagram as shown inFigure 1 As shown in the figure, it comprises a display 1, a signal transceiver device 2, a positioning device 3, a direction identification device 4 and a processor 5.

[0049] The positioning device 3 communicates with the communication positioning device in real time. The positioning device 3 can use the GPS (Global Positioning System) or Beidou satellite positioning method to position the communication positioning device.

[0050] The direction identification device 4 identifies the orientation of the communication positioning device in real time.

[0051] The signal transceiver device 2 is used for receiving and sending signals. The signals received by the signal transceiver device 2 can be position signals or voice signals sent by other target devices.

[0052] The processor 5 obtains the position signals sent by at least one target device within a preset range received by the signal transceiver device 2; determines the orientation information between the communication positioning device and the target device based on the first positioning coordinates of the communication positioning device, the orientation and the second positioning coordinates in the position signals; controls the display 1 to display the orientation relationship between the communication positioning device and the target device based on the orientation information. The target device can be a device with the same structure as the communication positioning device, i.e., multiple communication positioning devices can send position signals to each other to realize mutual positioning among the multiple communication positioning devices.

[0053] It should be noted that the signal transceiver device 2 can receive position signals sent by multiple devices within a preset range, and the signal transceiver device 2 can also send the position signals of the communication positioning device to multiple devices within a preset range. Referring to Figure 2 , the processor 5 determines the position relationship between the communication positioning device and the target device after receiving the position signals of one or more target devices, and displays each target device within the preset range with the communication positioning device as the origin. The display interface of the display 1 for displaying the orientation relationship between the communication positioning device and each target device further comprises a wheel for displaying the orientation, which marks the north direction, the south direction, the east direction, the west direction and the angles corresponding to different scales between directions. The angle corresponding to the north direction is 0° and 360°, the angle corresponding to the south direction is 180°, the angle corresponding to the east direction is 90°, and the angle corresponding to the west direction is 270°.

[0054] As Figure 2As shown, the display 1 of the communication positioning device can display the orientation between the communication positioning device and the target device, and can also display the orientation between the devices at the same time, and the orientation of the communication positioning device at the current position is displayed by a pointer. Specifically, the position signal sent by the target device contains not only the positioning coordinates of the target device, but also the orientation of the target device, and the orientation of the target device is a direction set with the north direction as the reference, and the orientations of the target device and the communication positioning device are determined by the direction angle with the north direction as the reference. Therefore, the display 1 is also used to display the orientation of the target device and the orientation of the communication positioning device.

[0055] The communication positioning device updates the positioning coordinates and the orientation of the communication positioning device in real time, and also receives the position signal sent by the target device in real time, and updates the orientation between the communication positioning device and the target device on the display 1 according to the preset time period.

[0056] The processor 5 is a CPU (Central Processing Unit).

[0057] For example, the communication positioning device A sends a position signal to the communication positioning device B, the positioning device in the communication positioning device B positions itself, the direction recognition device determines the orientation of the communication positioning device B, the processor determines the orientation information between the communication positioning device A and the communication positioning device B according to the positioning coordinates and the orientation of the communication positioning device B and the positioning coordinates of the communication positioning device A in the position signal, and the display displays the orientation between the two. The user wearing the communication positioning device B can intuitively check the direction and the approximate distance of the user of the communication positioning device A from the display. Similarly, the communication positioning device B can also send a position signal to other communication positioning devices (for example, the communication positioning device C), and the other communication positioning devices receiving the position signal sent by the communication positioning device B also perform the operation process of the communication positioning device B.

[0058] Specifically, the communication positioning device of the present application can be a wearable device with a display. The display 1 on the communication positioning device is a detachable display, which can be fixed on the main body of the communication positioning device (the main body includes a signal transceiver, a positioning device, a direction recognition device and a processor) by a card slot, a buckle or magnetic attraction and the like. For example, the communication positioning device can be a watch, and the display dial of the watch is a detachable dial; the communication positioning device can be smart glasses, and the lens of the glasses can be a clip-on lens, which is used to display the orientation between the glasses and other devices; the communication positioning device can be a smart headset, and the side of the headset is provided with a buckle, and a small display can be embedded in the side of the headset to display the orientation.

[0059] When the display 1 is separated from the main body of the communication positioning device, the display 1 is connected to the processor in the main body of the communication positioning device through wireless communication (such as Bluetooth or NFC (Near Field Communication), etc.); when the display 1 is fixed on the main body of the communication positioning device, the display 1 can be connected to the processor 5 in the main body of the communication positioning device through wireless communication or electrical connection, etc.

[0060] Optionally, the communication positioning device can further include a microphone for receiving voice data input by a user, and the processor 5 controls the display to display a call identification (such as Figure 3 The same, the processor 5 can also convert the voice data into a voice signal and send it to other devices. Wherein, the signal receiving device 2 can receive the voice signal sent by the same device when receiving the position signal.

[0061] In an implementation scenario, if multiple people carry out rescue tasks outdoors, each user carries a communication positioning device. Wherein, when a user needs to meet other users, the user applies the communication positioning device A worn by the user to send a positioning request to the communication positioning device B worn by other users within a preset range, at this time, B receives the request, and through the positioning device of B, the current position of user B is positioned, and the signal receiving device sends the position signal carrying the positioning coordinates to the communication positioning device A. A sends a request through the positioning device and the direction recognition device to determine the orientation of the communication positioning device A, and the signal receiving device of A receives the position signal of user B, and the processor in A determines the positional relationship between user A and user B according to the received position signal and the positioning coordinates and orientation obtained by itself, and displays it on the display interface of the display.

[0062] It should be noted that the positioning coordinates obtained by the positioning device for positioning the communication positioning device are latitude and longitude coordinates.

[0063] In the embodiment of the application, as Figure 4 The direction recognition device 4 of the communication positioning device includes a gyroscope 41, a magnetometer 42 and an accelerometer 43.

[0064] The gyroscope 41 is used to measure the angular velocity of the communication positioning device; the magnetometer 42 is used to measure the earth's magnetic field strength at the current position of the communication positioning device; and the accelerometer 43 is used to measure the acceleration of the communication positioning device.

[0065] Specifically, the gyroscope 41 measures angular velocity based on Coriolis force or vibration, measuring the rate of rotation of the device around three axes to track its rotational motion. The three-axis angular velocity (rotation rate around the X, Y, and Z axes) is measured in radians per second (rad / s) or degrees per second. The magnetometer 42 determines the orientation of the communication positioning device relative to the geomagnetic north pole by detecting the strength of the Earth's magnetic field. The accelerometer 43 measures acceleration based on inertial force; when the user-worn communication positioning device is stationary, its output includes a component of gravitational acceleration, from which the tilt angle of the communication positioning device can be inferred.

[0066] In determining the orientation of the communication positioning device, the magnetometer 42 is the primary sensor. Based on the Earth's magnetic field strength measured by the magnetometer, the orientation relative to the magnetic north pole is determined. A spatial rectangular coordinate system is then constructed, with the magnetic north pole as the X-axis, the geocentric direction as the Z-axis, and east as the Y-axis. The initial orientation of the communication positioning device in this spatial rectangular coordinate system is determined based on the magnetic field components of the Earth's magnetic field strength obtained by the magnetometer 42. This initial orientation is then corrected using the angular velocity of the gyroscope 41 and the acceleration of the accelerometer 43. Specifically, the initial orientation is determined in the XOZ plane of the spatial coordinate system (see reference). Figure 5 The coordinate system on the left side of the middle plane) and the YOZ plane (reference) Figure 5 The initial orientation is determined by deflection in the coordinate system on the right. If the initial orientation deflects in the first or fourth quadrant of the XOZ plane, the new orientation is considered positive. Conversely, if the initial orientation deflects in the second or third quadrant of the XOZ plane or the second or third quadrant of the YOZ plane, the equipment may be malfunctioning, and it is necessary to re-acquire the Earth's magnetic field strength, angular velocity, and acceleration to re-determine the orientation.

[0067] In the communication positioning device provided in this embodiment of the invention, the spatial state of the communication positioning device is measured by the magnetometer 42, gyroscope 41 and accelerometer 43 in the direction recognition device 4, thereby determining the spatial orientation of the communication positioning device. The angular velocity measured by the magnetometer 42 is used as the main spatial component, and the spatial orientation is corrected by combining the acceleration component and the magnetic field component, thereby further improving the accuracy of the device orientation recognition.

[0068] In the embodiment of the present application, the communication positioning device can not only position other devices, but also request other devices to position it. Specifically, the communication positioning device sends a position signal carrying the first positioning coordinate of the communication positioning device through the signal transceiver. The signal transceiver 2 can be a signal antenna. The signal transceiver 2 can adjust the signal transceiving range by adjusting the length of the signal antenna. Since the signal transceiving range of the signal transceiver 2 is limited, the processor 5 determines the broadcast range according to the preset broadcast frequency when sending the signal through the signal transceiver. The broadcast range is the preset range in which the communication positioning device can receive and send signals.

[0069] Optionally, the processor 5 determines the signal transceiving range according to the current setting state of the signal transceiver 2. The setting state is the broadcast frequency, and the signal transceiving range is the broadcast range. For example, the signal antenna adjusts the length to set the broadcast frequency.

[0070] In one embodiment, when the user of the communication positioning device needs to position other communication positioning devices, the signal transceiver 2 sends a positioning request signal. After receiving the positioning request signal, the other devices feed back a position signal carrying the positioning coordinate through the signal transceiver 2 of the device.

[0071] In another embodiment, when the user of the communication positioning device needs other devices to position the communication positioning device, the signal transceiver 2 directly sends the position signal of the communication positioning device to all devices in the broadcast range.

[0072] Optionally, the communication positioning device of the present application can further be provided with an operation assembly. The processor 5 sends a position signal carrying the first positioning coordinate to the target device through the signal transceiver. Specifically, when receiving the positioning operation performed by the user through the operation assembly, the processor 5 determines the target device for communication positioning based on the operation information of the positioning operation. The operation information includes the device code of the target device, the signal broadcast range, and the signal transceiving mode input by the user through the operation assembly when operating the operation assembly, and the like. The processor 5 sends a position signal carrying the first positioning coordinate to the target device through the signal transceiver.

[0073] The operation assembly can be a component composed of multiple operation buttons or operation switches. The user can send the position signal of the communication positioning device to the specified device by operating the operation assembly.

[0074] The plurality of operation buttons on the communication positioning device can be used to specify the device to be communicated with, for example, the numbers 0-9 are arranged on the operation buttons, and the user inputs the device number of the device to be communicated with by operating the buttons, and the processor 5 sends a positioning request signal or a position signal to the device corresponding to the device number according to the input device number through the signal transceiver 2.

[0075] The plurality of operation buttons on the communication positioning device can be used to specify the signal broadcast range of the received position signal, so as to send the position signal to each device in the broadcast range.

[0076] The plurality of operation buttons or operation switches on the communication positioning device can be used to set the signal transceiving mode. For example, when the operation assembly is an operation switch, whether the signal needs to be received can be determined by the switch state of the operation switch.

[0077] In an embodiment of the present application, after obtaining the positioning coordinates and the orientation of the communication positioning device, the orientation of the communication positioning device is taken as the positive direction, and the azimuth information between the communication positioning device and the target device is determined in combination with the second positioning coordinates in the position information of the target device, the azimuth information including the distance and the relative angle between the communication positioning device and the target device. The structure of the target device can also include the display 1, the signal transceiver 2, the positioning device 3, the direction recognition device 4 and the processor 5, and the second positioning coordinates are the latitude and longitude coordinates obtained by positioning the target device by the positioning device in the target device.

[0078] The processor 5 determines the azimuth information between the communication positioning device and the target device, specifically, the distance and the relative angle between the communication positioning device and the target device. The distance between the communication positioning device and the target device is determined based on the first positioning coordinates and the second positioning coordinates, and the relative angle between the communication positioning device and the target device is determined based on the first positioning coordinates, the second positioning coordinates and the orientation.

[0079] Since the first positioning coordinates and the second positioning coordinates are latitude and longitude coordinates, not plane coordinates, only the latitude and longitude coordinates need to be converted into radian system, and the distance between the two points is calculated to obtain the distance between the communication positioning device and the target device. That is, the first positioning coordinates and the second positioning coordinates are converted into first radian coordinates and second radian coordinates respectively, and the distance between the communication positioning device and the target device is calculated according to the longitude radian and the latitude radian in the first radian coordinates and the second radian coordinates.

[0080] For the relative angle between the communication positioning device and the target device, the azimuth angle between them needs to be calculated. Since the azimuth angle is calculated based on the north direction of the communication positioning, there is a deviation between the communication positioning device and the north direction, so the angle between the communication positioning device and the north direction is taken as the offset, and the azimuth angle is reduced by the offset to obtain the relative angle between the communication positioning device and the target device. Based on the longitude radian in the first and second radian coordinates, the longitude radian difference of the two radian coordinates is calculated. Based on the longitude radian difference, the latitude radian in the first radian coordinate and the latitude radian in the second radian coordinate, the azimuth angle is calculated. Based on the orientation of the communication positioning device, the angle between the device and the north direction (offset angle) is determined, and the relative angle between the two devices is obtained by reducing the offset angle from the azimuth angle.

[0081] Specifically, the first positioning coordinate and the second positioning coordinate are converted into the first radian coordinate and the second radian coordinate The conversion formula is as follows:

[0082]

[0083]

[0084] After converting the longitude and latitude into radian system, the longitude radian difference of the longitude radian in the two coordinates is calculated , wherein is the longitude radian in the second radian coordinate of the target device, is the longitude radian in the first radian coordinate of the communication positioning device.

[0085] The calculation formula of the azimuth angle is:

[0086]

[0087]

[0088] , wherein is the latitude radian in the second radian coordinate of the target device, is the latitude radian in the first radian coordinate of the communication positioning device. Since each parameter used in the calculation process of the azimuth angle is in radian system, it needs to be converted into angle, and the specific conversion formula is:

[0089]

[0090] If , then .

[0091] It should be noted that after the distance and the relative angle between the communication positioning device and the target device are obtained, the local map corresponding to the preset range can be obtained by reducing the preset range according to a preset scaling ratio. The local map corresponding to the preset range is generated on the display interface of the display with the current position of the communication positioning device as the origin. The relative position relationship between the communication positioning device and the target device is displayed in the local map according to the relative angle and the distance between the target device and the communication positioning device.

[0092] Optionally, in order to further reflect the relative position relationship between the target device and the communication positioning device, the display 1 displays a position-related dial in the local map of the display interface when the local map is generated. When the orientation of the communication positioning device changes, the dial in the display interface is updated.

[0093] In an embodiment, the orientation of the communication positioning device can always point to the same direction in the display interface. When the actual orientation of the communication positioning device changes, the pointer for indicating the direction in the display interface does not change, but the dial in the display interface rotates to indicate that the orientation of the communication positioning device has changed. As shown in FIG. 2A, the pointer for indicating the orientation of the communication positioning device in the display interface points to the north direction. When the communication positioning device turns 30° to the left, the dial in the display interface rotates, the pointer does not rotate, and the pointer of the communication positioning device points to the 330° direction. At the same time, due to the rotation of the dial in the display interface, the orientation of the target device changes, and the pointer of the target device rotates. Figure 6 In another embodiment, the dial in the display interface is fixed and does not change when the orientation of the communication positioning device changes. The pointer for indicating the direction rotates. As shown in FIG. 2B, the pointer for indicating the orientation of the communication positioning device in the display interface points to the north direction. When the communication positioning device turns 30° to the left, the dial in the display interface does not rotate, the pointer rotates, and the pointer points to the 330° direction.

[0094] Figure 7 In another embodiment, the dial in the display interface is fixed and does not change when the orientation of the communication positioning device changes. The pointer for indicating the direction rotates. As shown in FIG. 2B, the pointer for indicating the orientation of the communication positioning device in the display interface points to the north direction. When the communication positioning device turns 30° to the left, the dial in the display interface does not rotate, the pointer rotates, and the pointer points to the 330° direction.

[0095] In another embodiment, when the orientation and position of the communication positioning device do not change, and the orientation and / or position of the target device change, the dial and the pointer for indicating the orientation of the communication positioning device in the display interface also do not change. The display interface only updates the orientation and / or position of the target device in the local map.
