Description

Positioning device, intelligent watch and electronic equipment
Technical Field
The invention relates to the technical field of intelligent watches, and particularly provides a positioning device, an intelligent watch and electronic equipment.
Background
With the development of wearable and portable electronic devices such as smart watches, the demands for functions thereof are increasing. The need to be satisfied is to locate a target object by using the smart watch or to guide a user to reach the position of the target object. The function can play a role in searching for a mobile phone or an automobile.
However, the existing smart watch can only measure the distance of the target and cannot obtain the direction of the target. Therefore, the accurate position of the target cannot be obtained, the target can be found to be far away from the target after a certain distance is taken out, and the target is corrected to be found again in the direction. This is inefficient in finding the target and presents many inconveniences to the seeker.
Therefore, there is a need in the art for a positioning device, a smart watch and an electronic device to solve the above-mentioned problems.
Disclosure of Invention
The invention aims to solve the technical problems, namely the problem that an object cannot be accurately positioned.
In a first aspect, the present invention provides a positioning device comprising:
The first UWB antenna unit is used for acquiring distance information of a target;
The second UWB antenna unit is in communication connection with the first UWB antenna unit, and the first UWB antenna unit and the second UWB antenna unit are matched to acquire the direction information of the target.
In a specific embodiment of the positioning device, the first UWB antenna unit and the second UWB antenna unit form an antenna module;
The positioning device comprises a plurality of antenna modules, and the search ranges of the plurality of antenna modules are at least partially misaligned.
In a specific embodiment of the positioning device, the positioning device includes two antenna modules.
In a specific embodiment of the positioning device, the positioning device further includes a housing, and the antenna module is disposed in the housing.
In a specific embodiment of the positioning device, the housing is provided with a first mounting surface and a second mounting surface which are not on the same plane;
one of the antenna modules is arranged on the first mounting surface;
The other antenna module is arranged on the second mounting surface.
In a specific embodiment of the positioning device, the positioning device further includes a first module, configured to obtain a position of the target, where a search radius of the first module is greater than search radii of the first UWB antenna unit and the second UWB antenna unit.
In a specific embodiment of the positioning device, the first module is a GPS module.
In a specific embodiment of the above positioning device, the positioning device further includes:
and the display module is used for displaying the position of the target based on the information acquired by the first UWB antenna unit, the second UWB antenna unit and the first module.
In a second aspect, the present invention provides a smart watch provided with the above-mentioned positioning device, which is capable of searching for a target in front of a wearer of the smart watch when the wearer lifts his wrist to observe the smart watch.
The third convenience is that the invention provides an electronic device, and the positioning device is arranged in the electronic device.
Under the condition that the technical scheme is adopted, the positioning device provided by the invention can obtain the distance information of the target in the searching range through the first UWB antenna unit according to the UWB technology, and obtain the direction information of the target in the searching range through the first UWB antenna unit and the second UWB antenna unit, and can accurately position the target in the searching range by combining the distance information and the direction information. When the positioning device is applied to portable electronic equipment such as a smart watch and a mobile phone, the positioning device can be used for conveniently and accurately positioning a close-range target, such as a vehicle, a UWB tag and other electronic equipment.
Furthermore, the search range of each group of the first UWB antenna unit and the second UWB antenna unit is limited in a certain angle, and the angle of the search range of the positioning device can be enlarged by arranging a plurality of groups of the first UWB antenna unit and the second UWB antenna unit, the search ranges of which are not completely overlapped. Therefore, when the target is positioned, the frequency of adjusting the direction of the searching range of the positioning device can be reduced, so that the positioning is faster and more convenient.
Further, since the positioning distance of the UWB antenna is limited, a first module is added to the positioning device. The first module is positioned farther apart but with insufficient positioning accuracy. The approximate range of the target position can thus be determined by the first module. When the positioning device is close to the target, accurate positioning is performed through the UWB antenna unit and the UWB processing unit. This can expand the search range of the positioning device.
Furthermore, the positioning device can utilize a screen of the display module or the intelligent watch to show the distance and the direction of the target in the searching range of the antenna module, or the approximate position of the target in the searching range of the first module outside the searching range of the antenna module, so that a user can conveniently acquire positioning information.
Further, for the smart watch provided with the above positioning device, when a wearer of the smart watch lifts his wrist to observe the smart watch, the positioning device can search for a target in front of the wearer. The setting mode is convenient for a user to observe the positioning information of the display target on the intelligent watch when the user advances, adjust the advancing direction according to the direction information, judge when to stop advancing according to the distance information, and guide the wearer to reach the target position.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Furthermore, it should be noted that, in the description of the present invention, unless explicitly specified and limited otherwise, the terms "mounted," "configured," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be directly connected, can be indirectly connected through an intermediate medium, and can also be communicated with the inside of two elements. The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to the specific circumstances.
The existing intelligent watch can only measure the distance of the target and cannot obtain the direction of the target. Therefore, the accurate position of the target cannot be obtained, the target can be found to be far away from the target after a certain distance is taken out, and the target is corrected to be found again in the direction. This is inefficient in finding the target and presents many inconveniences to the seeker. In order to solve the technical problem, the embodiment discloses an electronic device, particularly an intelligent watch, which can accurately position a target.
It should be noted that, although the electronic device in this embodiment is a smart watch, this is not a limitation of the present invention, and other electronic devices may be adopted by those skilled in the art in other embodiments without departing from the principles of the present invention, for example: cell phones, smart bracelets, and other portable or wearable electronic devices, which do not depart from the basic principles of the invention and thus fall within the scope of the invention.
Referring to fig. 1, the smart watch includes a positioning device, wherein the positioning device includes a first UWB antenna unit 1, a second UWB antenna unit 2, and a housing 5. Specifically, the first UWB antenna unit 1 and the second UWB antenna unit 2 are disposed within the housing 5 by a Laser Direct Structuring (LDS) technique. The first UWB antenna unit 1 and the second UWB antenna unit 2 constitute an antenna module. The antenna module can receive signals sent by targets in a certain search range. Specifically, the search range is approximately hemispherical.
Referring to fig. 2, the positioning device is provided with a plurality of antenna modules. The search range of each antenna module is at least partially misaligned. The arrangement mode can enlarge the overall search range of the intelligent watch, namely, the positioning range of the positioning device. Preferably, the positioning means comprise two antenna modules, named first antenna module 3 and second antenna module 4, respectively.
Referring to fig. 3, the housing 5 has an approximately rectangular parallelepiped shape, and the housing 5 includes an upper side wall and a lower side wall having a large area, and four side walls having a narrow area, and inner surfaces of the four side walls are a first mounting surface 51, a second mounting surface 52, a third mounting surface 53, and a fourth mounting surface 54, respectively.
Referring to fig. 1, a screen 8 is provided on an upper side wall of the housing 5, and a lower side wall disposed opposite to the upper side wall is for attachment to a wrist of a wearer.
Referring to fig. 2, the first mounting surface 51 is provided with the first antenna module 3, and the first search range 31 of the first antenna module 3 is a hemispherical range having an end surface on which the plane of the first mounting surface 51 is located. The second mounting surface 52 is provided with the second antenna module 4, and the second search range 41 of the second antenna module 4 is a hemispherical range having an end face on the plane of the second mounting surface 52. The first mounting surface 51 is perpendicular to the second mounting surface 52. By the arrangement mode, after the first searching range 31 and the second searching range 41 are overlapped, the positioning range of the intelligent watch can be expanded to be close to 270 degrees, and the sphere center of the positioning range is the intelligent watch.
With continued reference to fig. 1, in the normal use state of the smart watch described above, the first search range 31 is directed to the front of the human body 11, and the second search range 41 is directed to the right or left of the human body 11. Preferably, the second search range 41 is directed to the right side of the human body 11. When a wearer of a smart watch lifts his wrist to view the smart watch, the forearm of the person wearing the smart watch is typically horizontally positioned in front of the wearer. In a common use state of the smart watch, the search range of the antenna module should include the front and the right side of the smart watch. This arrangement facilitates the wearer's progress to the target location as directed by the smart watch.
Referring to fig. 4 and 5, the positioning device further includes a UWB processing unit 9, and the first antenna module 3 and the second antenna module 4 are connected to the UWB processing unit 9. The UWB processing unit 9 can calculate the distance and direction of the target from the information acquired by the antenna module. Specifically, the first UWB antenna unit 1 is capable of transmitting a first signal, and a target within the search range is capable of receiving the first signal and transmitting a second signal, and the first UWB antenna unit 1 and the second UWB antenna unit 2 are each capable of receiving the second signal transmitted by the target within the search range. The UWB processing unit 9 can calculate the distance between the target and the first UWB antenna unit 1 based on the time when the first UWB antenna unit 1 transmits the first signal and the time when the second signal is received. The UWB processing unit 9 is capable of calculating the azimuth Angle of the target (i.e., angle-of-Arrival principle) based on the phase difference of the second signals received by the first UWB antenna unit 1 and the second UWB antenna unit 2.
With continued reference to fig. 4, the positioning device further includes a first module, whose search radius is larger than the search radii of the first UWB antenna unit 1 and the second UWB antenna unit 2, and is mainly used for searching for a target outside the search range of the antenna module. In the present embodiment, the first module adopts the GPS module 6, and the GPS antenna 61 is connected to the GPS module 6. Specifically, the GPS antenna 61 is L-shaped, and two sides of the L-shaped GPS antenna 61 are respectively disposed on the third mounting surface 53 and the fourth mounting surface 54 of the housing 5 of the smart watch, as shown in fig. 3 and 6.
The GPS module 6 can acquire a target position outside the search range of the antenna module through the GPS antenna 61. The target position obtained by the GPS module 6 is not accurate enough and the GPS module 6 can be used as a complement to the antenna module described above. When the antenna module cannot obtain the position of the target (i.e. the target is located outside the search range of the antenna module), the approximate position of the target can be obtained by the GPS module 6.
With continued reference to fig. 4, the positioning device further includes a display module 7, the screen 8 is electrically connected to the display module 7, and the display module 7 is capable of controlling the display content of the screen 8.
The positioning device further comprises a processor 10. The UWB processing unit 9, the GPS module 6 and the display module 7 are all electrically connected to the processor 10. When the target is not within the search range of the antenna module but within the search range of the first module, the UWB processing unit 9 does not receive the target position information, and the GPS module 6 can obtain the approximate position of the target. At this time, the processor 10 controls the display module 7 to cause the screen 8 to display the approximate position of the target obtained by the GPS module 6. When the target is located within the search range of the antenna module, the UWB processing unit 9 calculates the distance and direction of the target based on the information fed back from the antenna module, and the processor 10 controls the display module 7 to cause the screen 8 to display the distance and direction of the target so as to guide the user to reach the target position.
The intelligent watch is internally provided with a power module 12, and the power module 12 supplies power to the UWB processing unit 9, the GPS module 6, the display module 7 and the processor 10.
Thus far, the technical solution of the present invention has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present invention is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present invention, and such modifications and substitutions will fall within the scope of the present invention.
