Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, in particular to an interconnection method and device based on UWB. BACKGROUND

[0002] Ultra Wide Band (UWB) is a wireless carrier communication technology, which transmits data by using nanosecond non-sine wave narrow pulse, so its frequency spectrum range is very wide. UWB has the advantages of low system complexity, low transmitting signal power spectrum density, insensitivity to channel fading, low interception ability, high positioning accuracy, etc., and is especially suitable for high-speed wireless access in dense multipath places such as indoor places.

[0003] UWB is essentially a non-carrier spread spectrum technology using impulse with very low duty cycle as information carrier, and the impulse has high positioning accuracy, so UWB can realize the combination of positioning and communication.

[0004] However, in the prior art, only the communication ability or the positioning ability of UWB technology is usually utilized, and there is no method for realizing interaction by simultaneously utilizing the combination of positioning and communication. SUMMARY

[0060] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] Figure 1 This is a diagram illustrating the application environment of a UWB-based interconnection method in one embodiment. (Refer to...) Figure 1 This UWB-based interconnection method is applied to a UWB-based interconnection system. The UWB-based interconnection method includes a master UWB 110 and a slave UWB 120. The master UWB 110 and the slave UWB 120 can be connected via a wireless network. In the method of this embodiment, the slave UWB 120 may include multiple slaves.

[0062] In this embodiment of the invention, the master UWB110 and slave UWB120 are distinguished only from the perspective of data transmission; the master UWB110 and slave UWB120 are no different in terms of circuit structure, function, or capabilities. In one embodiment, the master UWB110 can also be the slave UWB120 in another embodiment, and similarly, the slave UWB120 in one embodiment can also be the master UWB in another embodiment.

[0063] In this embodiment of the invention, the master UWB110 and slave UWB120 are typically mobile terminals, which can specifically be at least one of mobile phones, tablets, laptops, etc. The mobile terminal provides access to the user via a speaker, horn, and / or headphone device, including wired and / or wireless headphones.

[0064] The UWB-based interconnection method of the present invention is applied to the master UWB110 and / or the slave UWB120.

[0065] Figure 2 The diagram shown is a flowchart of a UWB-based interconnection method according to an embodiment of the present invention. Figure 2 As shown, the method is applied to a UWB interconnect system, which includes a master UWB and a slave UWB. The method includes:

[0066] Step 210: The main UWB acquires the working mode;

[0067] Step 220: The master UWB obtains whether the slave UWB exists within a preset range centered on the master UWB;

[0068] Step 230: The master UWB establishes a pairing connection with the slave UWB based on the distance to the slave UWB within the preset range, the working mode, and the pairing parameters of the slave UWB.

[0069] In the method of this embodiment of the invention, the master UWB establishes a pairing connection with the slave UWB based on whether there is a slave UWB within a preset range centered on the master UWB, and based on the distance to the slave UWB within the preset range, the operating mode, and the pairing parameters of the slave UWB. In this method, the UWB is not only used to detect the existence of other UWBs within the preset range, but also to detect the distance between other UWBs, and automatically establishes a pairing connection based on distance and other factors. This fully utilizes the communication and positioning capabilities of UWB, realizing UWB-based positioning, ranging, and interconnection.

[0070] In this embodiment of the invention, the working mode includes single-person mode and multi-person mode, and the pairing parameters include: historical pairing and no historical pairing.

[0071] In this embodiment of the invention, the working modes include single-person mode and multi-person mode. The interconnection method of different working modes will be described below.

[0072] In this embodiment of the invention, "historical pairing" means that the master UWB and a certain slave UWB have previously established a pairing.

[0073] In step 230, the master UWB establishes a pairing connection with the slave UWB based on the distance to the slave UWB within the preset range, the operating mode, and the pairing parameters of the slave UWB, including:

[0074] If the working mode is single-person mode, then:

[0075] The master UWB determines whether there are any historically paired slave UWBs among the slave UWBs within the preset range;

[0076] If there exists a slave UWB with the aforementioned historical pairing, then the master UWB will use the slave UWB with the aforementioned historical pairing as the first UWB to be paired.

[0077] The main UWB obtains the first real-time distance between itself and the first UWB to be paired.

[0078] If the first real-time distance is less than or equal to the first preset distance, the main UWB establishes a pairing connection with the first UWB to be paired.

[0079] Wherein, after the master UWB obtains the first UWB to be paired, it no longer obtains the distance to slave UWBs other than the first UWB to be paired.

[0080] Since acquiring distance from the primary UWB requires energy, in single-player mode, after acquiring the distance to the first UWB to be paired, the system stops acquiring the distance to other UWBs besides the first UWB to be paired, which can reduce system energy consumption.

[0081] In this embodiment of the invention, after the master UWB establishes a pairing connection with the slave UWB based on the distance to the slave UWB within the preset range, the operating mode, and the pairing parameters of the slave UWB, the method further includes:

[0082] The master UWB sets the pairing parameters of the slave UWB that establishes the pairing connection to historical pairing.

[0083] In this embodiment of the invention, if there are multiple historically paired slave UWBs, then:

[0084] The master UWB selects one of the multiple historically paired slave UWBs as the first UWB to be paired according to a first preset rule;

[0085] The main UWB acquires the first real-time distance with the first UWB to be paired in real time;

[0086] If the first real-time distance is less than or equal to the first preset distance, then the main UWB establishes a pairing connection with the first UWB to be paired.

[0087] In this embodiment of the invention, after the primary UWB establishes a pairing connection with the first UWB to be paired, the method further includes:

[0088] The second real-time distance between the master UWB and the slave UWB with which a pairing connection has been established is obtained in real time;

[0089] If the second real-time distance is greater than or equal to the second preset distance, then disconnect the pairing connection with the UWB that has already established a pairing connection;

[0090] Wherein, the second preset distance is greater than the first preset distance.

[0091] When the working mode is single-user mode, the master UWB will determine whether there is a historically paired slave UWB among the slave UWBs within the preset range. If there is only one historically paired slave UWB, the master UWB will obtain the first real-time distance with the slave UWB in real time. When the first real-time distance is less than the first preset distance, the master UWB establishes a pairing connection with the slave UWB. At this time, the master UWB still detects the distance with the already paired slave UWB. When the second real-time distance between the master UWB and the slave UWB increases and exceeds the second preset distance, the master UWB disconnects the pairing connection with the slave UWB.

[0092] If the master UWB detects that there are multiple historically paired slave UWBs within a preset range, it selects one of the multiple historically paired slave UWBs as the first to be paired UWB according to the first preset rule, and establishes a pairing connection and disconnects the connection based on the distance between the master UWB and the first to be paired UWB.

[0093] In this embodiment of the invention, the first preset rule is:

[0094] From the multiple historically paired slave UWBs, the slave UWB with the closest distance is selected as the first UWB to be paired; or

[0095] Of the multiple historically paired slave UWBs, the slave UWB with the highest priority is selected as the first UWB to be paired; or

[0096] Of the multiple historically paired slave UWBs, the slave UWB that is closest to the one that allows automatic connection will be selected as the first UWB to be paired.

[0097] In this embodiment of the invention, the first preset rule includes, but is not limited to, the above description, and can be set according to needs and application scenarios.

[0098] In single-player mode, after the master UWB obtains the first UWB to be paired, it will no longer obtain the distance to slave UWBs other than the first UWB to be paired.

[0099] In this embodiment of the invention, pairing and connection are performed based on historical pairings. That is, for previously paired UWBs, a reconnection session can be automatically initiated based on distance conditions, which can eliminate the need for subsequent steps such as allowing automatic connection and requesting pairing. Furthermore, when users move further apart to a second preset distance, the original session will also be automatically disconnected, achieving automatic connection and automatic disconnection.

[0100] In this embodiment of the invention, in order to improve the security performance of the system, a mechanism can be set that requires confirmation from UWB before a pairing connection can be established, or a "allow automatic connection" setting can be pre-configured from UWB before a pairing connection can be established.

[0101] In this embodiment of the invention, in step 230, the master UWB establishes a pairing connection with the slave UWB based on the distance to the slave UWB within the preset range, the operating mode, and the pairing parameters of the slave UWB, including:

[0102] If the working mode is a multi-user mode, then:

[0103] The master UWB selects a slave UWB as the second pairing UWB according to the second preset rule;

[0104] The primary UWB establishes a pairing connection with the second UWB to be paired;

[0105] The main UWB obtains a third UWB to be paired according to a third preset rule;

[0106] The master UWB disconnects the pairing connection with the slave UWB that has already established a pairing connection, and establishes a pairing connection with the third UWB to be paired.

[0107] In this embodiment of the invention, the second preset rule is:

[0108] From multiple historically paired UWBs, the closest UWB is selected as the second UWB to be paired; or

[0109] From multiple historically paired UWBs, the one with the highest priority is selected as the second UWB to be paired; or

[0110] Among multiple historically paired slave UWBs, the slave UWB that is closest to the one that allows automatic connection will be selected as the second UWB to be paired.

[0111] Among multiple historically paired slave UWBs, the slave UWB that actively sends the pairing request will be designated as the second UWB to be paired.

[0112] In this embodiment of the invention, the third preset rule is:

[0113] If a paired UWB has not actively sent a pairing request, then any UWB that actively sent a pairing request will be designated as the third UWB to be paired; or

[0114] If a paired UWB has not actively sent a pairing request, the highest-priority UWB among those that actively sent a pairing request will be designated as the third UWB to be paired; or

[0115] If a paired UWB actively initiates a pairing request, the UWB with the highest priority among those that actively initiated the pairing request will be designated as the third UWB to be paired; or

[0116] The UWB with priority of "Special Skills" will be designated as the third UWB to be paired.

[0117] In this embodiment of the invention, the slave UWB can proactively send a pairing request, meaning it can disconnect / establish a pairing connection according to user needs. In one embodiment, if the slave UWB needs to establish a pairing connection with the master UWB, it can proactively send a pairing request and establish a pairing connection with the master UWB; if it does not need to establish a pairing connection, the slave UWB can also proactively disconnect the connection.

[0118] In this embodiment of the invention, one of the differences between the multi-player mode and the single-player mode is that in the single-player mode, after the master UWB obtains the first pairing UWB, it no longer obtains the distance between other slave UWBs, while in the multi-player mode, after obtaining the second pairing UWB, it will continue to obtain the distance between other UWBs.

[0119] In this embodiment of the invention, the second difference between the multi-user mode and the single-user mode is that, in the single-user mode, after the master UWB establishes a connection with a slave UWB, it can only establish a pairing connection with other slave UWBs after the distance between the master UWB and the slave UWB exceeds a second preset distance; while in the multi-user mode, after the master UWB obtains the third UWB to be paired according to the third preset rule, it will cut off the connection with the slave UWB that has already established a pairing connection, and establish a pairing connection with the third UWB to be paired.

[0120] In this embodiment of the invention, single-user mode and multi-user mode are suitable for different application scenarios and application needs, and can also coexist in the same application scenario. For example, one or more UWBs may use single-user mode, while one or more other UWBs may use multi-user mode. The mode used by the UWB can also be switched according to needs, thereby meeting the needs of different users and different application scenarios.

[0121] like Figure 3 As shown, the present invention also provides a UWB-based interconnection device, which is applied to a UWB interconnection system. The UWB interconnection system includes a master UWB and a slave UWB, and the device is disposed in the master UWB. The device includes:

[0122] Pattern acquisition unit 310 is used to acquire working modes.

[0123] The ranging unit 320 is used to determine whether the slave UWB exists within a preset range centered on the main UWB;

[0124] The main control unit 330 is used to establish a pairing connection with the slave UWB based on the distance to the slave UWB within the preset range, the working mode, and the pairing parameters of the slave UWB.

[0125] In this embodiment of the invention, the working mode includes a single-person mode, and the pairing parameters include: historical pairings and no historical pairings;

[0126] The main control unit 330 is also used for:

[0127] If the working mode is single-person mode, then:

[0128] Determine whether there are any historically paired slave UWBs within the preset range;

[0129] If there exists a historically paired slave UWB, then that historically paired slave UWB is designated as the first UWB to be paired.

[0130] The first real-time distance between the device and the first UWB to be paired is obtained in real time.

[0131] If the first real-time distance is less than or equal to the first preset distance, then a pairing connection is established with the first UWB to be paired;

[0132] Specifically, after obtaining the first UWB to be paired, the distance to other UWBs outside the first UWB to be paired is no longer obtained.

[0133] In this embodiment of the invention, if there are multiple historically paired slave UWBs, the master control unit 330 is further configured to:

[0134] According to a first preset rule, one of the multiple historically paired UWBs is selected as the first UWB to be paired;

[0135] The first real-time distance between the device and the first UWB to be paired is obtained in real time.

[0136] If the first real-time distance is less than or equal to the first preset distance, a pairing connection is established with the first UWB to be paired.

[0137] In this embodiment of the invention, the main control unit 330 is further configured to:

[0138] Real-time acquisition of the second real-time distance between the paired UWB and the established pairing connection;

[0139] If the second real-time distance is greater than or equal to the second preset distance, then disconnect the pairing connection with the UWB that has already established a pairing connection;

[0140] Wherein, the second preset distance is greater than the first preset distance.

[0141] In this embodiment of the invention, the first preset rule is:

[0142] From the multiple historically paired slave UWBs, the slave UWB with the closest distance is selected as the first UWB to be paired; or

[0143] Of the multiple historically paired slave UWBs, the slave UWB with the highest priority is selected as the first UWB to be paired; or

[0144] Of the multiple historically paired slave UWBs, the slave UWB that is closest to the one that allows automatic connection will be selected as the first UWB to be paired.

[0145] In this embodiment of the invention, the working mode includes a multi-person mode, and the pairing parameters include: historical pairings and no historical pairings;

[0146] The main control unit 330 is also used for:

[0147] If the working mode is a multi-user mode, then:

[0148] According to the second preset rule, select one UWB as the second UWB to be paired;

[0149] Establish a pairing connection with the second UWB to be paired;

[0150] The third UWB to be paired is obtained according to the third preset rule;

[0151] Disconnect the pairing connection between the UWB and the UWB that has already established a pairing connection, and establish a pairing connection with the third UWB to be paired.

[0152] In this embodiment of the invention, the second preset rule is:

[0153] From multiple historically paired UWBs, the closest UWB is selected as the second UWB to be paired; or

[0154] From multiple historically paired UWBs, the one with the highest priority is selected as the second UWB to be paired; or

[0155] Among multiple historically paired slave UWBs, the slave UWB that is closest to the one that allows automatic connection will be selected as the second UWB to be paired.

[0156] Among multiple historically paired slave UWBs, the slave UWB that actively sends the pairing request will be designated as the second UWB to be paired.

[0157] In this embodiment of the invention, the third preset rule is:

[0158] If a paired UWB has not actively sent a pairing request, then any UWB that actively sent a pairing request will be designated as the third UWB to be paired; or

[0159] If a paired UWB has not actively sent a pairing request, the highest-priority UWB among those that actively sent a pairing request will be designated as the third UWB to be paired; or

[0160] If a paired UWB actively initiates a pairing request, the UWB with the highest priority among those that actively initiated the pairing request will be designated as the third UWB to be paired; or

[0161] The UWB with priority of "Special Skills" will be designated as the third UWB to be paired.

[0162] In this embodiment of the invention, the main control unit 330 is further configured to:

[0163] Set the pairing parameters from UWB to historical pairings when establishing a pairing connection.

[0164] In this embodiment of the invention, UWB is not only used to detect whether other UWBs exist within a preset range, but also to detect the distance between other UWBs, and automatically establishes a pairing connection based on the distance, etc., making full use of the communication and positioning capabilities of UWB, and realizing UWB-based positioning, ranging and interconnection.

Claims

1. A UWB-based interconnection method, characterized in that, The method is applied to a UWB interconnect system, the UWB interconnect system including a master UWB and a slave UWB, and the method includes: The main UWB acquires the working mode; The main UWB determines whether the slave UWB exists within a preset range centered on the main UWB; The master UWB establishes a pairing connection with the slave UWB based on the distance to the slave UWB within the preset range, the working mode, and the pairing parameters of the slave UWB. The working mode includes a single-person mode, and the pairing parameters include: historical pairings and no historical pairings; The master UWB establishes a pairing connection with the slave UWB based on the distance to the slave UWB within the preset range, the operating mode, and the pairing parameters of the slave UWB, including: If the working mode is single-person mode, then: The master UWB determines whether there are any historically paired slave UWBs among the slave UWBs within the preset range. If a historical pairing exists, the master UWB will use that historical pairing as its first UWB to be paired. The primary UWB obtains the first real-time distance between itself and the first UWB to be paired. If the first real-time distance is less than or equal to the first preset distance, then the main UWB establishes a pairing connection with the first UWB to be paired. Wherein, after the master UWB obtains the first UWB to be paired, it no longer obtains the distance to slave UWBs other than the first UWB to be paired; The working mode includes a multi-person mode, and the pairing parameters include: historical pairing and no historical pairing; The master UWB establishes a pairing connection with the slave UWB based on the distance to the slave UWB within the preset range, the operating mode, and the pairing parameters of the slave UWB, including: If the working mode is a multi-user mode, then: The master UWB selects a slave UWB as the second UWB to be paired according to a second preset rule. The primary UWB establishes a pairing connection with the second UWB to be paired. The main UWB obtains the third UWB to be paired according to the third preset rule. The master UWB disconnects the pairing connection with the slave UWB that has already established a pairing connection, and establishes a pairing connection with the third UWB to be paired.

2. The method according to claim 1, characterized in that, If multiple historical pairings exist from UWB, then: The master UWB selects one of the multiple historically paired slave UWBs as the first UWB to be paired according to a first preset rule; The main UWB acquires the first real-time distance with the first UWB to be paired in real time; If the first real-time distance is less than or equal to the first preset distance, then the main UWB establishes a pairing connection with the first UWB to be paired.

3. The method according to claim 1 or 2, characterized in that, After the primary UWB establishes a pairing connection with the first UWB to be paired, the method further includes: The master UWB acquires the second real-time distance between itself and the slave UWB with which a pairing connection has been established; If the second real-time distance is greater than or equal to the second preset distance, the master UWB disconnects the pairing connection with the slave UWB that has established a pairing connection. Wherein, the second preset distance is greater than the first preset distance.

4. The method according to claim 2, characterized in that, The first preset rule is: Among the multiple historically paired slave UWBs, the slave UWB that is closest in distance is selected as the first UWB to be paired. or Among the multiple historically paired slave UWBs, the slave UWB with the highest priority is selected as the first UWB to be paired. or Of the multiple historically paired slave UWBs, the slave UWB that is closest to the one that allows automatic connection will be selected as the first UWB to be paired.

5. The method according to claim 1, characterized in that, The second preset rule is: From multiple historically paired UWBs, the closest UWB is selected as the second UWB to be paired. or Among multiple historically paired UWBs, the one with the highest priority is selected as the second UWB to be paired. or Among multiple historically paired slave UWBs, the slave UWB that is closest to the one that allows automatic connection will be selected as the second UWB to be paired. Among multiple historically paired slave UWBs, the slave UWB that actively sends the pairing request will be designated as the second UWB to be paired.

6. The method according to claim 1, characterized in that, The third preset rule is: If a paired UWB has not actively sent a pairing request, then any UWB that actively sent a pairing request will be designated as the third UWB to be paired; or If a paired UWB has not actively sent a pairing request, the UWB with the highest priority among the UWBs that actively sent a pairing request will be designated as the third UWB to be paired. or If a paired UWB actively sends a pairing request, the UWB with the highest priority among those that actively sent the pairing request will be designated as the third UWB to be paired. or The UWB with priority of "Special Skills" will be designated as the third UWB to be paired.

7. The method according to claim 1, characterized in that, After the master UWB establishes a pairing connection with the slave UWB based on the distance to the slave UWB within the preset range, the operating mode, and the pairing parameters of the slave UWB, the method further includes: The master UWB sets the pairing parameters of the slave UWB that establishes the pairing connection to historical pairing.
