Detailed Description
In order to enable those of ordinary skill in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the foregoing figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. The embodiments described in the examples below are not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Fig. 1 is a block diagram illustrating a system 100 for implementing group functions according to an exemplary embodiment of the present invention. The system 100 may be installed in a variety of electronic devices to enable the electronic devices to implement group functionality. For ease of explanation, it is assumed that a first device has installed the system 100 and may use the system 100 to implement group functions with other devices that have installed the system 100.
The system 100 according to an exemplary embodiment of the present invention may include a group opening module 110, a group creation module 120, and a connection module 130.
The group opening module 110 may be configured to open a group function and the group creation module 120 may be configured to create a group. In an exemplary embodiment of the present invention, the first device may turn on a group function using the group on module 110 and create a group using the group creation module 120 and then join other devices that also install the system 100 to the group created by itself, or the first device may turn on a group function using only the group on module 110 and then join a group created by another device without creating a group, as will be explained in detail below.
When the group function is turned on and the group is created in the first device, the connection module 130 may search one or more devices that have turned on the group function and do not join the group created by the first device and determine a distance and a pointing relationship between the first device and the one or more devices, and when a distance between the first device and a second device of the one or more devices is within a preset distance range and a pointing relationship exists between the first device and the second device, the connection module 130 may establish a direct connection between the first device and the second device and add the second device to the group. Then, the second device joining the group may also search for other devices within a preset distance range that have turned on the group function and have not joined the group, thereby joining the device in a pointing relationship with the second device to the group.
And when the group function is turned on in the first device but the group is not created, the first device may be added to another group created by another device in a similar manner as the first device adds the second device to the group created by the first device as described above. After the first device has been added to another group created by another device, the connection module 130 of the first device may also search for at least one device that has turned on the group function and has not joined the other group and determine a distance and a pointing relationship between the first device and the at least one device, and when a distance between the first device and a third device of the at least one device is within the preset distance range and a pointing relationship exists between the first device and the third device, establish a direct connection between the first device and the third device and add the third device to the other group.
That is, in an exemplary embodiment of the present invention, devices already in a group may search for and join devices that satisfy the above distance and pointing relationship conditions but do not join the group, thereby establishing a decentralised temporary group. This will be explained in more detail later.
In an exemplary embodiment of the invention, the existence of a pointing relationship between devices means that one device points to another device or that another device points to the device. And the absence of a pointing relationship between devices means that one device does not point to another device and that the other device does not point to the device.
Further, in the exemplary embodiment of the present invention, for convenience of explanation and distinction, a device that created a group (e.g., the above-described first device) and a device that has joined the group (e.g., the above-described second device that has joined the group) may be referred to as a group device, and a device that will join the group (but has not joined the group) (e.g., the above-described other device searched by the second device) may be referred to as a target device.
According to an exemplary embodiment of the present invention, when device a turns on a group function and creates a group, device a may be referred to as a group device. After the group device a determines that the target device B points to the group device a within the preset distance range, the group device a may establish a direct connection with the target device B and join the target device B to the group of the group device a by the group device a. At this time, the target device B becomes the group device B, and the group device B may similarly search for other devices within the preset distance range.
Then, when the group device B determines that the target device C with the group function turned on points to the group device B within the preset distance range, the target device C may establish a direct connection with the group device B, and the group device B joins the target device C into the group where the group device a and the group device B are located. At this time, the target device C becomes the group device C, and the group device C may similarly search for other devices within the preset distance range.
Alternatively, when the group device a determines that the group device a points to the target device D with the group function turned on within the preset distance range, the group device a may also establish a direct connection with the target device D, and join the target device D to the group of the group device a by the group device a.
Further, according to an exemplary embodiment of the present invention, when the group device a determines that a specific device having an on group function has a pointing relationship with the group device a within a preset distance range and the group device B determines that the specific device also has a pointing relationship with the group device B within the preset distance range, one or both of the group device a and the group device B may establish a direct connection with the specific device and join the specific device to the group of the group device a and the group device B.
For example, when the group device a determines that a specific device that has turned on the group function has a pointing relationship with the group device a within a preset distance range, and the group device B determines that the specific device also has a pointing relationship with the group device B within the preset distance range, the specific device may compare the distance with the group device a and the distance with the group device B. For example, if the distance to group device a is greater than the distance to group device B, then that particular device may establish a direct connection with group device B and join the group of group device a and group device B; if the distance to group device a is less than the distance to group device B, then the particular device may establish a direct connection with group device a and join the group of group device a and group device B.
Alternatively, when the first group device determines that a specific device that has turned on the temporary group function has a pointing relationship with the first group device within a preset distance range and the second group device determines that the specific device has a pointing relationship with the second group device within a preset distance range (the groups in which the first group device and the second group device are located are different, respectively, the first group and the second group), the specific device may join the first group and the second group at the same time, or the specific device may select the two groups to determine joining one of the first group and the second group before establishing a direct connection with the first group device and the second group device.
Further, according to an exemplary embodiment of the present invention, when the device a turns on the group function but does not create a group, if the device a can be searched by the group device X in another group and the device a has a pointing relationship with the group device X within a predetermined distance range, the group device X may add the device a to the other group, at which time the device a becomes the group device a of the other group. Subsequently, the device a may also search for other devices within the preset distance range, which will not be described here.
However, it should be understood that the above description with reference to the accompanying drawings is merely enumerated for clarity of understanding of the technical concept of the present application, and the present application is not limited thereto, and the above-described manner of establishing a group and joining a group is also applied to other cases, for example, even if a first device turns on a group function and creates a group, the first device may be added to a group created by other devices in the above-described manner of joining a group.
The manner in which the group device determines the distance and pointing relationship with the target device is described in detail below.
In an exemplary embodiment of the present invention, the connection module 130 of the group device may include a location module (not shown), e.g., a UWB location module, an RFID location module, a bluetooth location module, a WiFi location module, or a ZigBee location module, etc., for determining a distance and pointing relationship between the group device and the target device. For example, when the positioning module included in the connection module 130 is a ZigBee positioning module, a certain number of base stations may be deployed in a specific environment by ZigBee technology, and when the base stations receive information sent by the devices in real time, the information is uploaded to a server, and the distance and the pointing relationship between the devices can be determined through calculation processing of the server. For another example, when the positioning module included in the connection module 130 is a UWB positioning module, the positioning module may be configured to determine a distance and an angle between the group device and the target device, wherein when the angle of the group device and the target device is within a preset angle range, the connection module 130 may determine that a pointing relationship exists between the group device and the target device.
By way of example only, an example of determining a distance and pointing relationship between a target device and a group device using UWB as a positioning module (hereinafter referred to as UWB positioning module (not shown)) will be described in detail below in connection with fig. 2 and 3 (the detailed description will be given below taking as an example whether the target device points to the group device).
Fig. 2 is a diagram illustrating a determination of coordinates of a target device according to an exemplary embodiment of the present invention; and fig. 3 is a diagram illustrating a determination of a distance between a target device and a group device according to an exemplary embodiment of the present invention.
As shown in fig. 2, the UWB positioning module of the group device is illustrated as including three antennas (the UWB positioning module may further include more than three antennas). The three antennas of the UWB positioning module may be P 1、P2 and P 3 in a preset coordinate system, respectively, where the outer center O of the triangle obtained by connecting the three antennas P 1、P2 and P 3 may be the origin of coordinates of the preset coordinate system. Here, the coordinates of OP 1＝OP2＝OP3,P1 may be the coordinates of P 1(x1,y1,0),P2 may be P 2(x2,y2, 0) and the coordinates of P 3 may be P 3(x3,y3, 0), the coordinates of all three antennas being known in the exemplary embodiment of the present invention. The target device may be abstracted as a P point in the preset coordinate system, and the coordinates of the P point may be P (x, y, z).
An example of determining the distance of each of the three antennas to the target device is described below.
As shown in fig. 3, antenna P 1 of the group device may transmit a data packet to the target device at time T 1, the target device may receive a data packet from antenna P 1 of the group device at time T 2 and transmit a reply data packet to antenna P 1 at time T 3, and antenna P 1 may receive a reply data packet from the target device at time T 4. Here, in fig. 3, T delay is a time delay between a time T 2 when the target device receives the packet and a time T 3 when the reply packet is transmitted. T delay may be preset. The TF is the period of time during which a data packet or reply data packet is transmitted. The reply packet may include information about the time T 2 at which the target device received the packet, information about T delay, and information about the time T 3 at which the target device sent the reply packet.
The group device may calculate a distance d 1 between an antenna P 1 of the group device and the target device P in the preset coordinate system by the following equation (1):
Wherein C is the wave velocity.
In the same way, distances d 2 and d 3 between the antennas P 2 and P 3 of the target device and the group device, respectively, can be calculated.
As shown in fig. 2, since d 1、d2 and d 3 have been calculated in the above steps, the coordinates P (x, y, z) of the target device can be calculated by the following equations (2) to (4):
thus, the distance OP between the group device and the target device can be calculated.
In addition, it can be calculated by the following equation (5)And/>Wherein the coordinates P (x, Y, z) have been obtained by the above procedure, the vector/>, of the Y-axis can be determinedThe coordinates are set to (0, 1, 0).
When the angle θ is less than or equal to the preset angle, it may be determined that the target device is pointing to the group device.
The above examples describe a process of calculating the distance and angle between a group device and a target device based on UWB technology. Those skilled in the art will recognize that this description is exemplary only and that the scope of the invention is not so limited.
Furthermore, in exemplary embodiments of the present invention, when a device is added to a group, the device may establish a direct connection only with the device that added the device to the group, or may also establish a direct connection with other devices in the group after joining the group.
The manner in which data is transmitted between devices in a group is described in detail below.
Fig. 4 is a schematic diagram illustrating a data transmission manner between devices in a group according to an exemplary embodiment of the present invention.
As shown in fig. 4, after the a device determines that the B device, the C device, and the D device have a pointing relationship with the a device within a preset distance range, the a device may establish a direct connection with the B device, the C device, and the D device, and join the B device, the C device, and the D device to a group created by or in which the a device is located, and after the C device determines that the E device has a pointing relationship with the C device within a preset distance range, the C device may establish a direct connection with the E device, and join the E device to a group in which the C device is located, where the E device is indirectly connected with the a device, the B device, and the D device in the group.
In this case, when the a device transmits data, the B device, the C device, and the D device may simultaneously receive the data transmitted by the a device, and after the C device completes receiving the data, the C device may forward the data to the E device.
Further, in this case, when the C device transmits data, the a device and the E device may simultaneously receive the data transmitted by the C device, and after the a device finishes receiving the data, the a device may forward the data to the D device and the B device.
That is, when one device in a group transmits data, a device in the group directly connected to the device receives the data and forwards the data stepwise to a device in the group indirectly connected to the device.
Fig. 5 is a schematic diagram illustrating a data transmission manner between devices in the group when there is a device exit in the group of fig. 4 according to an exemplary embodiment of the present invention.
In the group of fig. 4, if the C device is disconnected from the a device (or the C device exits the group), the C device may transmit information about the E device to the a device, and then the a device may establish a direct connection with the E device. Alternatively, if the C device disconnects from the a device (or the C device exits the group), the C device may also send information about the a device to the E device, which may then establish a direct connection with the a device. That is, when the C device is disconnected from the a device, a direct connection is established between the a device and the devices in the group that are directly connected to the C device, such that the disconnection of the C device in the group does not affect the one-to-many data transfer between the other devices in the group.
In this case, as shown in fig. 5, when the a device transmits data, the E device, the B device, and the D device may simultaneously receive data transmitted by the a device.
Further, in this case, when the E device transmits data, the a device may receive the data transmitted by the E device, and after the a device finishes receiving the data, the a device may forward the data to the B device and the D device.
Fig. 6 is a schematic diagram illustrating a data transmission manner between devices in a group according to another exemplary embodiment of the present invention.
As shown in fig. 6, after the a device determines that the B device has a pointing relationship with the a device within a preset distance range, the a device may establish a direct connection with the B device, and join the B device into the group of the a device; after the B device determines that the C device has a pointing relationship with the B device within the preset distance range, the B device may establish a direct connection with the C device and join the C device in the group, and the B device may send connection information with the C device to the a device to which the B device has been connected, so that the a device may establish a direct connection with the C device newly joining the group. Alternatively, after the C device joins the group, the B device may send all its connection information to the C device so that the C device newly joining the group may establish a direct connection with all the devices in the group.
In this case, when the a device transmits data, the B device and the C device may simultaneously receive data transmitted by the a device. That is, after a device is added to a group, the device establishes a direct connection with all devices in the group, and when any device in the group transmits data, other devices in the group except for the any device receive the data at the same time.
In this case, when any device in the group disconnects or exits the group, one-to-many data transfer between other devices in the group is not affected.
Further, for example, when a specific device in the group, which is joined by a certain device, cannot establish a direct connection with an a device because of a large distance, the specific device may search for a device in the group, which is within a certain distance range and is directly connected with the a device, and establish a direct connection with the device, and when the a device transmits data, the device in the group, which is within a certain distance range and is directly connected with the a device, may receive the data and may forward the data to the specific device. Alternatively, when device a sends data, the certain device that caused the particular device to join the group may forward the data to the particular device.
The devices in the group may connect and transfer data based on the bluetooth protocol, but are not limited thereto, e.g., may also be based on WiFi, RFID, NFC protocols, etc.
The operation of the devices in the group to exit the group is described in detail below. The system 100 according to an exemplary embodiment of the present invention may further include an exit module (not shown) that may be configured to cause a device to exit the joined group when the device performs a predetermined action.
Fig. 7 shows a schematic diagram of a device exiting a group according to an exemplary embodiment of the invention. For example only, in fig. 7, devices in a group may exit the group by flipping.
The motion state of the device can be identified according to the data of a gyroscope, a sensor and the like in the device, and when any device in the group is turned from the front to the back within a preset time range (for example, the time of turning degree is close to 180 degrees is less than 400 ms), the device can directly exit the group.
The preset time range may be an average value obtained by turning the phone test with the right hand. For example, the preset time range may be set to 400ms.
As shown in fig. 7 (1) and (2), the device being flipped from the horizontal front to the horizontal back may refer to the absolute value of the degree of flipping of the device about the Y axis being greater than a preset degree, e.g., 175 degrees. That is, when a device in portrait screen is flipped rapidly left or right from the front more than a preset number of degrees within a preset time frame, the device may exit the group directly.
As shown in fig. 7 (3) and (4), the device being flipped from the horizontal front to the horizontal back may refer to the absolute value of the degree of flipping of the device about the X-axis being greater than a preset degree, e.g., 175 degrees. That is, when the device in the landscape screen is turned inside out or turned outside out from the front more than a preset number of degrees quickly within a preset time range, the device can directly exit the group.
Examples of the device being flipped quickly are not limited to the above examples, and for example, when the device being in the landscape screen is flipped quickly left or right from the front more than a preset number of degrees within a preset time range, the device may also exit the group directly.
The operation of the gyroscope in the device to calculate the flip angle of the device to identify the motion state of the device will be described in detail below in connection with fig. 8.
Fig. 8 shows a flowchart for identifying a motion state of a device according to an exemplary embodiment of the present invention. For example only, a gyroscope is used in fig. 8 to identify the motion state of the device.
When the device joins the group, the device may register the gyroscope and may specify a polling interval of the gyroscope (step S801), for example, the polling interval may be specified as 20ms.
The gyroscope may acquire a speed at which the device is flipped around the X-axis or the Y-axis (step S802), and may calculate absolute values θ x and θ y of angles at which the device is flipped around the X-axis or the Y-axis within a preset time range (e.g., 400 ms) (step S803). When θ x and θ y are greater than or equal to a preset value or close to a preset value (for example, the preset angle may be pi) (yes at step S804), the device may de-register the gyroscope, at which point the device may exit the group (step S805). When θ x and θ y are less than or not close to the preset value (no at step S804), the device may continue to remain in the group.
The above-described operation of exiting the group of devices is merely an example, and the operation of exiting the group of devices may also include other predetermined actions, such as pressing a predetermined key, tapping a screen, shaking the device, etc. The operation of the device exiting the group may also be user-defined. When any device in the group performs a predetermined action, the any device exits the group.
Fig. 9 is a schematic diagram illustrating file transfer between a plurality of devices of a plurality of users according to an exemplary embodiment of the present invention.
First, as shown in (1) of fig. 9, the user a can open a temporary group function on the handset and create a temporary group; as shown in (2) of fig. 9, the user B may open the temporary group function on the mobile phone and automatically join the temporary group after pointing to the mobile phone of the user a within a predetermined distance range; as shown in (3) of fig. 9, the user C may turn on the temporary group function on the mobile phone and automatically join the temporary group after pointing to the mobile phone of the user B within a predetermined distance range. As shown in fig. 9 (4), user a may send a file on his handset to the temporary group, and as shown in fig. 9 (5), both user B and user C's handsets may receive the file. As shown in (6) of fig. 9, if any of the user a, the user B, and the user C turns over the cellular phone, the user exits the temporary group.
Fig. 10 is a schematic diagram illustrating file transfer between a plurality of devices of one user according to an exemplary embodiment of the present invention.
First, as shown in (1) in fig. 10, a user opens a temporary group function on a mobile phone and creates a temporary group; as shown in (2) of fig. 10, a user opens a temporary group function on a television, directs a mobile phone to the television within a predetermined distance range, and the television can automatically join the temporary group; as shown in (3) of fig. 10, the user opens the temporary group function on the notebook and directs the mobile phone to the notebook within a predetermined distance range, and the notebook can automatically join the temporary group. As shown in (4) of fig. 10, the user may send a file to the temporary group on the notebook; as shown in (5) of fig. 10, the user can receive the file on the mobile phone and the television. As shown in fig. 10 (6), if the user turns the handset over, the handset exits the temporary group. In addition, the notebook or television may exit the temporary group by other means, for example, the user performs a predetermined operation on the notebook or television to cause the notebook or television to exit the temporary group, or the user performs a predetermined operation on the mobile phone to cause the notebook or television to exit the temporary group when the mobile phone is in the temporary group.
Fig. 11 is a flowchart illustrating a method for implementing a group function according to an exemplary embodiment of the present invention.
According to an exemplary embodiment of the present invention, first, it is determined whether a first device has a group function turned on and whether a group is created (steps S1101 and S1102), and when the first device has the group function turned on and the group is created (yes at step S1101 and yes at step S1102), one or more devices that have the group function turned on and have not joined the group created by the first device are searched for by the first device and a distance and a pointing relationship between the first device and the one or more devices are determined (step S1103). When the distance between the first device and the second device of the one or more devices is within the preset distance range and a pointing relationship exists between the first device and the second device, a direct connection is established between the first device and the second device, and the second device is added to the group by the first device (step S1104).
When the first device turns on the group function but does not create a group (yes at step S1101 and no at step S1102), and the first device has been added to another group created by another device (yes at step S1112), at least one device that has turned on the group function and has not joined the other group is searched for by the first device and a distance and pointing relationship between the first device and the at least one device is determined (step S1113). When the distance between the first device and the third device of the at least one device is within the preset distance range and a pointing relationship exists between the first device and the third device, a direct connection is established between the first device and the third device, and the third device is added to the other group by the first device (step S1114).
In the exemplary embodiment of the present invention, the above-described second device and third device may represent not only a single device but also a plurality of devices. For example, when a distance between a first device and a plurality of second devices of the one or more devices is within a preset distance range and a pointing relationship exists between the first device and the plurality of second devices, direct connections are established between the first device and the plurality of second devices, respectively, and the plurality of second devices are added to a group by the first device. Further, after the first device adds the plurality of second devices to the group, the first device may continue searching for other devices to be added to the group or may not perform a search any more under a specific operation of the user.
This has been described in detail above in connection with fig. 1 to 6, and thus will not be described here again.
By identifying the position and angle between the devices based on a specific positioning technique, when any device has a pointing relationship with the central device, the central device can join the any device into the group of the central device, and at the same time, any device can also become the central device, that is, all devices in the group can become the central device, so that more users can conveniently and quickly join the group.
Each device in the group is connected with each other through a transmission protocol, any device sends a file, and other devices can receive the file, so that a data transmission system of one-to-many devices is constructed, data transmission of one-to-many devices can be realized without a network server, and privacy leakage and high requirements on network connection are avoided.
By identifying the actions of the devices in the group, when any device in the group performs a predetermined action (for example, turns from the horizontal front surface to the horizontal back surface), the any device can exit the group, so that complex exiting operation after the user joins the group is avoided, and smooth experience of the user when using the temporary group function is improved.
