The central device 12 may be networked with one or more slave devices (eg, slave devices 14) into a second secondary network. Among the plurality of central devices, one central device may be determined to be the main central device (for example, the central device 11), and the remaining central devices are sub-central devices (for example, the central device 12). The main central device can establish a communication connection with the secondary central device, forming multiple secondary networks into a high-level network. For example, the central device 11 can establish a communication connection with the central device 12 to form a first secondary network and a second secondary network into a high-level network. In the embodiment of the present application, the first secondary network and the second secondary network can also be combined. advanced network The network is called the first advanced network.

The central device 15 may form a third secondary network with one or more other slave devices. Among them, the central device 11 is the main central device, and the central device 15 and the central device 12 are the sub-central devices. The central device 11 can establish communication connections with the central device 15 and the central device 12 respectively, and connect the first secondary network, the second secondary network and the third secondary network to form a second high-level network.

The application scenarios of the advanced network provided by the embodiments of this application are introduced below.

The system 10 shown in Figure 1 can be applied in a multi-screen collaboration scenario to realize drag-and-drop file transfer between different central devices, between different slave devices, or between a central device and slave devices. In a multi-screen collaboration scenario, the system 10 may include multiple electronic devices with screens, such as tablet computers, monitors, laptop computers, and so on. As an example, the system 10 includes a tablet computer and a display. The tablet computer and the display may be central devices in the system 10 (for example, central device 11, central device 12, or central device 15), or they may be central devices in the system 10. slave device (for example, slave device 13 or slave device 14). The tablet and display can form advanced networks with other central and/or slave devices. For example, the tablet computer and monitor can form a secondary network using the networking method shown in Figure 4A below, and then use the networking method shown in Figure 5A below to form multiple secondary networks with the central devices of other secondary networks. An advanced network. Tablets and monitors can communicate with each other based on this advanced network and establish a multi-screen collaborative relationship.

Figures 2A and 2B show a schematic diagram of a multi-screen collaboration scenario provided by an embodiment of the present application.

As shown in Figure 2A, in a multi-screen collaboration scenario, taking the display 22 on the right side of the tablet computer 21 as an example, the tablet computer 21 can display an interface 1000, where a window 1001 is displayed on the interface 1000, and the window 1001 can be a video broadcast The display window can also be a document display window, a picture display window, etc. This application is not limited here. The tablet computer 21 may receive and respond to the user's right-drag operation on the window 1001 and drag the window 1001 to the right. Display 22 may display interface 2000. For example, the interface 2000 may be a desktop, and one or more icons (eg, movies, television, recycle bin, etc.) may be displayed on the desktop.

When the tablet computer 21 detects that the window 1001 is dragged to an area outside the right edge of the screen of the tablet computer 21 , the tablet computer 21 can send a message to the display 22 through an advanced network based on the multi-screen collaboration relationship between the tablet computer 21 and the display 22 . The first information is sent to notify the display 22 to display the portion of the window 1001 that is not displayed on the tablet computer 21 . The display 22 may receive and respond to the first information by displaying a portion of the window 1001 that is not displayed on the tablet computer 21 .

For example, as shown in FIG. 2B , the tablet computer 21 displays an interface 1100 and the display 22 displays an interface 2100 . Among them, a left window 1101 is displayed on the interface 1100, and the left window 1101 is the left part of the window 1001 in Figure 2A. A right window 2101 is displayed on the interface 2100. The right window 2101 is the right part of the window 1001 in Figure 2A, and the left window 1101 and the right window 2101 can jointly form the window 1001.

It should be noted that when the display 22 is on the right side of the tablet computer 21, when the window 1001 is dragged to an area outside other edges (left edge, top edge or bottom edge) of the tablet computer 21 screen, the display 22 still displays interface 2000.

It can be understood that in a multi-screen collaboration scenario, in addition to the windows displayed in the tablet 21 interface, other files (such as icons, video files, documents, etc.) can also be dragged from the tablet 21 Transmitted to the display 22 , or transmitted from the display 22 to the tablet computer 21 .

As can be seen from the above embodiments, in a multi-screen collaboration scenario, it is necessary to determine the orientation relationship between the tablet computer 21 and the display 22, that is, determine whether the tablet computer 21 is on the left, right, upper, or lower side of the display 22, so as to facilitate subsequent dragging. When dragging a file on the tablet computer 21, it is determined whether the display 22 needs to receive and/or display the dragged file. That is, before and after the tablet computer 21 and the display 22 establish a multi-screen collaboration relationship, the tablet computer 21 or the display 22 needs to determine the orientation relationship between the tablet computer 21 and the display 22 based on the high-level network where the tablet computer 21 and the display 22 are located. The specific method for determining the orientation relationship between the tablet computer 21 or the display 22 based on the advanced network can refer to the embodiment shown in FIG. 8 , which will not be described in detail here.

The system 10 can also be applied in vehicle scenarios to switch the voice mode of mobile phones and tablets by measuring the internal and external relationship between mobile phones, tablets and other electronic devices and the vehicle. In this application scenario, the system 10 may include a car, one or more electronic devices with audio modules, such as mobile phones, tablets, smart speakers, etc. As an example, the system 10 includes a car and a mobile phone. The car and the mobile phone may be central devices in the system 10 (for example, the central device 11, the central device 12, or the central device 15), or they may be slave devices in the system 10. (eg Slave 13 or Slave 14). The car and phone can form an advanced network with other central devices and/or slave devices. For example, the car and mobile phone can use the networking method shown in Figure 4A below to form a secondary network, and then use the networking method shown in Figure 5A below to form multiple secondary networks with the central equipment of other secondary networks. Advanced networking. Cars and mobile phones can communicate with each other based on this advanced network.

Figures 2C to 2D show a schematic diagram of a vehicle-mounted scenario provided by an embodiment of the present application.

As shown in FIG. 2C , the mobile phone 32 is outside the car 31 . In this case, when the mobile phone 32 determines that the mobile phone 32 is outside the car 31 based on the advanced network where the mobile phone 32 and the car 31 are located, the mobile phone 32 can determine that the audio mode is the first audio mode, and the audio module of the mobile phone 32 collects or Play audio files.

As shown in FIG. 2D , the mobile phone 32 is inside the car 31 . In this case, when phone 32 is based on phone 32 and car 31 When the advanced network where it is located determines that the mobile phone 32 is inside the car 31, the mobile phone can determine that the audio mode is the second audio mode, and collect or play audio files through the audio module of the car 31.

It can be seen from the above embodiment that in the vehicle scenario, the mobile phone 32 needs to determine the internal and external relationship between the mobile phone 32 and the car 31 through the advanced network where the mobile phone 31 and the mobile phone 32 are located. In this way, the internal and external relationship between the mobile phone 32 and the car 31 can be determined. audio mode. Among them, the specific method of determining the internal and external relationship between the mobile phone 32 and the car 31 based on the advanced network can refer to the embodiment shown in FIG. 8 , which will not be described in detail here in this application.

The system 10 can also be applied in distributed collaboration scenarios to achieve distributed collaborative work between different central devices, between different slave devices, or between central devices and slave devices through advanced networks. In a distributed collaboration scenario, for example, the system 10 includes a mobile phone and a tablet computer. The mobile phone and tablet computer may be the central device in the system 10 (for example, the central device 11, the central device 12, or the central device 15) , or it can be a slave device in the system 10 (for example, the slave device 13 or the slave device 14). The phones and tablets can form advanced networks with other central and/or slave devices. For example, the mobile phone and tablet computer can use the networking method shown in Figure 4A below to form a secondary network, and then use the networking method shown in Figure 5A below to form multiple secondary networks with the central equipment of other secondary networks. An advanced network. Tablets and mobile phones can communicate with each other based on this advanced network and establish a distributed collaborative relationship.

Figures 2E to 2F illustrate distributed collaboration scenarios provided by embodiments of the present application.

As shown in Figure 2E, a distributed collaboration relationship is established between the mobile phone 41 and the tablet computer 42. The mobile phone 41 displays an interface 3000. The interface 3000 may include a document directory. The document directory may include the names of one or more documents, such as operation guide 3001, meeting procedures, participant information, and so on. The tablet computer 42 displays an interface 4000. For example, the interface 4000 may be a desktop, and one or more icons (for example, movies, television, music, etc.) may be displayed on the desktop.

The mobile phone 41 can receive and respond to the user's click operation on the operation guide 3001 in the document directory. Based on the distributed collaboration relationship between the mobile phone 41 and the tablet computer 42, it sends the first step to the tablet computer 42 through the advanced network where the mobile phone 41 and the tablet computer 42 are located. The second information is used to instruct the tablet computer to display the text content of the operation guide. The tablet computer 42 can receive and respond to the second information sent by the mobile phone 41 and display the interface 4100 in Figure 2F. As shown in Figure 2F, the interface 4100 may include a document window 4101, which may be used to display the text content of the operation guide.

It should be noted that in a distributed collaboration scenario, the mobile phone 41 and the tablet 42 can also perform other collaborative work. For example, the tablet 42 can call the communication module of the mobile phone 41 to implement voice calls, and answer the calls of the mobile phone 41 through the tablet 42 Video calls, etc. are not limited in this application.

After the central device is turned on, it can send detection information to the surrounding areas in the form of broadcast. After the slave device receives the detection information sent by the central device, in response to the detection information, the slave device can send a detection response to the central device. The central device can determine the detected slave device based on the received detection response.

After the central device detects the presence of one or more slave devices around the central device, the central device may send a first networking request to the detected one or more slave devices respectively. The first networking request is used to request communication with the slave device. Establish a communication connection.

If it is determined that the slave device has not established a communication connection with other central devices, the slave device can send a first response to the central device. The first response can be used to inform the central device that the slave device can Establish a communication connection with the slave device. The first response may include connection parameters of the slave device, and the connection parameters of the slave device may be used to establish a communication connection with the slave device.

For example, when it is determined that the number of slave devices to which the central device has been connected is less than the maximum number of connectable devices of the central device, in response to the first response, the central device may establish a communication connection with the slave device. When it is determined that the number of slave devices connected to the central device is equal to the maximum number of central devices When the number of connectable devices is high, in response to the first response, the central device may not establish a communication connection with the slave device.

S405: The central device saves the network information of the secondary network where the central device is located.

Device types can include central devices and slave devices. The connection relationship can be used to indicate whether a communication connection is established between two devices in the secondary network.

Specifically, as shown in Table 1, the secondary network includes two devices, whose device identifiers are U1 and U2 respectively. Among them, the device type corresponding to the device ID U1 is the central device, the device type corresponding to the device ID U2 is the slave device, and a communication connection is established between the device ID U1 and the device ID U2. . According to the network information of the secondary network shown in Table 1, in the secondary network, the device identifier of the central device is U1, the device identifier of the slave device is U2, and a communication connection is established between the central device and the slave device.

It should be noted that the central device can save the network information of the secondary network after the secondary network is established. In another possible implementation, the central device can save the network information of the secondary network multiple times during the establishment process of the secondary network. For example, when the central device forms a secondary network with multiple slave devices, after establishing a communication connection with one of the slave devices, the central device can first save some of the network information of the secondary network related to the slave device, that is, first The device identification, device type, and connection relationship between the central device and the slave device are saved in the network information of the secondary network.

After the central device A is turned on, the central device A can actively detect whether there are other electronic devices around and send a first networking request to the detected electronic devices. For example, when central device A detects slave device M, slave device D, and slave device L, central device A can send a first networking request to slave device D, slave device M, and slave device L respectively. Please The slave device that receives the first networking request is required to establish a communication connection with central device A. After receiving the first networking request sent by the central device A, the slave device D can send a first response to the central device A, informing the central device A that a communication connection can be established with the slave device D. After receiving the first response, the central device A can establish a communication connection with the slave device D. Similarly, central device A can also establish connections with slave device L and slave device M according to the above-mentioned process of establishing a communication connection with slave device D. Therefore, the above-mentioned electronic devices can form a secondary network A0 with the central device A as the central device and the slave devices D, L and M as slave devices.

In some embodiments, the hardware score of the central device 11 is higher than the hardware score of the central device 12 , indicating that the central device 11 has higher hardware capabilities. Therefore, the central device 11 is determined to be the main central device of the advanced network, and the central device 12 is the secondary center. equipment. In other embodiments, the hardware score of the central device 12 is higher than the hardware score of the central device 11 , indicating that the central device 12 has higher hardware capabilities. Therefore, the central device 12 is determined to be the main central device of the advanced network, and the central device 11 is Secondary center equipment.

In a possible implementation, when the device type of the central device 12 is included in the network connection response sent by the central device 12 as the main central device, the central device 11 can also determine the central device based on the network connection response sent by the central device 12 12 is the main central equipment.

S504: The central device 11 establishes a communication connection with the central device 12.

After receiving the device type of the central device 12, the central device 11 may determine whether to establish a communication connection with the central device 12 based on the device type of the central device 12. In this embodiment, since the device type of the central device 12 is a central device, the central device 11 determines to establish a communication connection with the central device 12 .

In some embodiments, when the device receiving the cross-network request is a slave device, taking the slave device 14 as an example, the slave device 14 can send the device type of the slave device 14 (ie, slave device) to the central device 11, and the central device 11 receives Device from device 14 After the type, it may be determined not to establish a communication connection with the slave device 14 based on the device type of the slave device 14 .

S505: The central device 11 sends an information acquisition request to the central device 12, which is used to request the central device 12 to send network information of the second secondary network.

After the central device 11 and the central device 12 establish a communication connection, the first secondary network where the central device 11 is located and the second secondary network where the central device 12 is located can be connected through the central device 11 and the central device 12 to form a first high-level network. Network, the first high-level network includes a central device 11, a central device 12, a slave device 13 and a slave device 14, where the main central device is the central device 11 and the secondary central device is the central device 12.

When it is determined that the main central device of the first advanced network is the central device 11 , the central device 11 may send an information acquisition request to the central device 12 . The information acquisition request may include the identification of the main central device, which may be used to notify the central device 12 that the main central device of the first high-level network is the central device 11, and request the central device 12 to send the network information of the second secondary network to the main central device.

For example, Table 5 shows the network information of the second secondary network.

Table 5 Network information of the second secondary network

As shown in Table 5, the second secondary network includes two devices, whose device identifiers are U12 and U14 respectively. Among them, the device type corresponding to the device identification U12 is the central device, the device type corresponding to the device identification U14 is the slave device, and a communication connection is established between the device identification U12 and the device identification U14. . According to the network information of the secondary network shown in Table 5, in the second secondary network, the device identification of the central device 12 is U12, the device identification of the slave device 14 is U14, and the difference between the central device 12 and the slave device 14 is A communication connection is established between them.

It can be understood that when the main central device is determined to be the central device 12, the central device 12 can also send an information acquisition request to the central device 11, requesting the central device 11 to send the network information of the first secondary network to the central device 12. Applications are not limited here.

S506: The central device 12 sends the network information of the second secondary network where the central device 12 is located to the central device 11.

After receiving and responding to the information acquisition request, the secondary central device sends the network information of the secondary network where the central device is located to the main central device. That is, the central device 12 can send to the central device 11 the network information of the second secondary network where the central device 12 is located. Internet Information. For the network information of the second secondary network, please refer to the relevant description in Table 5 in the above step S505, which will not be described again here.

S507: The central device 11 saves the network information of the second secondary network.

After receiving the network information of the second secondary network, the central device 11 may save the network information of the second secondary network in the network information of the first high-level network.

Illustratively, taking the first high-level network as an example, Table 6 shows network information of a first high-level network.

Table 6 Network information of the first advanced network

As shown in Table 6, the first advanced network includes four devices, whose device identifiers are U11, U12, U13, and U14 respectively. Among them, the devices with device identifiers U11 and U13 belong to the first secondary network, and the devices with device identifiers U12 and U14 belong to the second secondary network. The device type corresponding to the device identification U11 is the main central device, the device type corresponding to the device identification U12 is the secondary central device, and the device type corresponding to the equipment identification U13 and U14 is the slave device. The device with the device ID U11 has communication connections with the devices with the device IDs U12 and U13 respectively, and the device with the device ID U12 has communication connections with the devices with the device IDs U11 and U14 respectively. According to the network information of the first high-level network shown in Table 6, it can be seen that the first high-level network includes a first secondary network and a second secondary network. The first secondary network includes a central device 11 and a slave device 13. The device identifier of the central device 11 is U11, and the device identifier of the slave device 13 is U13. A communication connection is established between the central device 11 and the slave device 13. The second secondary network includes a central device 12 and a slave device 14. The device identifier of the central device 12 is U12, and the device identifier of the slave device 14 is U14. A communication connection is established between the central device 12 and the slave device 14. A communication connection is established between the central device 11 and the central device 12, and the central device 11 is the main central device and the central device 12 is the secondary central device.

Using the above method, multiple secondary networks can be connected to form a high-level network. For example, in the multi-screen collaboration scenario shown in Figure 2A, the secondary network composed of the tablet computer 21 and the display can form a high-level network with other secondary networks based on the method shown in Figure 5A. For another example, in the vehicle scenario shown in Figure 2C, the secondary network composed of the car 31 and the mobile phone 32 can also form an advanced network with other secondary networks based on the method shown in Figure 5A above, etc., this application again No restrictions.

Since the main central device of the high-level network is selected from the central devices of the secondary network, rather than from all the devices of the high-level network, the selection efficiency of the central device is improved, and the efficiency of the network is also improved. In addition, using the structure of the above-mentioned advanced network, the slave device only needs to pass through at most one relay device to communicate with the central device, that is, the communication in the advanced network has lower latency.

Figure 5B shows a schematic structural diagram of a high-level network that is merged into multiple secondary networks.

As shown in Figure 5B, the high-level network 30 may include a secondary network A0, a secondary network B0 and a secondary network C0. For the specific content of the above three secondary networks, please refer to the relevant descriptions in the embodiment shown in Figure 4B. This application will not go into details here. The above three secondary networks can be combined into a high-level network using the method shown in Figure 5A.

For example, after the secondary network A0 is established, the central device A can send a network connection request to surrounding electronic devices (for example, slave device E, slave device N, slave device F, central device B, etc.). When the slave device receives the network connection request, taking slave device E as an example, slave device E can send the device type of slave device E to central device A, which is used to inform central device A that the device type of slave device E is a slave device. When central device B receives the network connection request, central device B can send the device type of central device B and the hardware configuration of central device B to central device A. After central device A determines that central device B is the central device, it can establish a communication connection with central device B to form an advanced network. In addition, central device A can determine that the main central device of the advanced network is central device B based on the hardware configuration of central device A and the hardware configuration of central device B.

When the secondary network C0 is completed, the secondary network A0 and the secondary network B0 have formed an advanced network. At this time, the central device C can send network connection requests to surrounding electronic devices. In this case, when central device B receives the network connection request sent by central device C, central device B can send the device type of central device B to central device C, using Inform central device C and central device B to be the main central device. After receiving the device type of central device B, central device C determines to establish a communication connection with central device B, and connects secondary network C0 to the high-level network with central device B as the central device. In this way, the above-mentioned high-level network composed of the secondary network A0 and the secondary network B0 can establish a connection with the secondary network C0 to form a larger high-level network 30.

It should be noted that during the merging process of secondary networks, the slave devices connected to the central device in each secondary network will not change. Furthermore, the center device B, as the main center device of the advanced network 30, can save the network information of the advanced network 30.

By way of example, Table 7 shows network information of the advanced network 30 .

As shown in Table 7, the advanced network 30 includes fourteen devices, whose device identifiers are A, B, C, D, E, F, G, H, I, J, K, L, M and N respectively. Among them, the devices with device identifiers A, D, L, and M belong to the secondary network A0, and the devices with device identifiers B, E, F, G, and N belong to the secondary network B0, and the device identifiers are C, H, and The devices of I, J and K belong to the secondary network C0. The equipment type corresponding to the equipment with equipment identification B is the main central equipment, and the equipment type corresponding to the equipment with equipment identifications A and C is secondary central equipment, and the equipment identifications are D, E, F, G, H, I, J respectively. , K, L, M and N devices correspond to device types as slave devices. The device with the device ID A has established communication connections with the devices with the device IDs B, D, L, and M respectively. The device with the device ID B has communication connections with the devices with the device IDs A, C, E, F, G, and N respectively. Communication connections are established between devices, and communication connections are established between the device with the device identifier C and the devices with the device identifiers B, H, I, J, and K respectively. According to the network information of the high-level network 30 shown in Table 7, the high-level network 30 includes a secondary network A0, a secondary network B0 and a secondary network C0. For the specific content of the secondary network A0, the secondary network B0 and the secondary network C0, reference can be made to the relevant content in the embodiment shown in FIG. 4B and will not be described again here. In the advanced network 30, central device B has established communication connections with central device A and central device C respectively, and central device B is the main central device, and central device A and central device C are secondary central devices.

Table 7 Network information of advanced network 30

In this way, the above three secondary networks can be merged into an advanced network 30 with central device B as the main central device, central device A and central device C as sub-central devices, and the remaining slave devices as slave devices.

Figure 6A shows a schematic flow chart of re-networking after the main central device goes offline.

The re-networking process after the main central device goes offline can be applied to any high-level network, and the high-level network can be composed of two or more secondary networks. The following takes the second-level network as an example to illustrate the process of re-networking after the main center device goes offline.

The second high-level network includes a central device 11, a central device 12, a central device 15, a slave device 13 and a slave device 14. The central device 11 and the slave device 13 form a network and the first secondary network is composed of the central device 12 and the slave device 14. In the second secondary network, the central device 15 and one or more other slave devices form a third secondary network. The central device 11 is the main central device, and the central device 11 establishes communication connections with the central device 15 and the central device 12 respectively. As shown in Figure 6A, when the main central device (i.e. central device 11) of the above-mentioned second advanced network is offline, the process of re-networking of the remaining central devices and slave devices may include the following steps:

S601. The central device 11 sends a first offline notification to the central device 15, which is used to notify the central device 15 that the central device 11 is offline.

When the central device 11 is offline, a first offline notification may be sent to the central device 15 that is connected to the central device 11. The first offline notification is used to notify the central device 15 that the central device 11 is offline.

In a possible implementation, the central device 11 can also send the first offline notification to the central device 12, or send the first offline notification to the central device 15 and the central device 12 respectively, which is not limited in this application.

In some embodiments, when the central device 11 goes offline unexpectedly (for example, due to a power outage, malfunction, etc.), other central devices (the central device 12 and the central device 15) that were originally connected to the central device 11 can be configured based on the connection with the central device 11. The communication connection determines that the central device 11 is offline. For example, the central device 12 may determine that the central device 11 is offline based on the disconnected communication connection between the central device 12 and the central device 11 , and the central device 15 may determine that the central device 11 is offline based on the disconnected communication connection between the central device 15 and the central device 11 .

S602: The central device 15 establishes a communication connection with the central device 12.

S603, the central device 15 determines the central device 15 as the new main central device.

After receiving and responding to the first offline notification, the central device 15 and the central device 12 can establish a communication connection, form the first secondary network and the second secondary network into a new high-level network (i.e., a new high-level network), and based on the central The hardware configuration of the device 15 and the hardware configuration of the central device 12 determine that the central device 15 is the main central device of the new advanced network.

It should be noted that both steps S602 and S603 are steps executed by the central device 15 in response to the first offline notification. There is no time limit for these two steps. They can be executed at the same time, or one of them can be executed first, and then Execute another one.

In one possible implementation, in response to the first offline notification, when it is determined that no information indicating that the central device 11 is back online is received within a first time threshold (for example, 5 seconds, 15 seconds, etc.), the central device 15 can establish a communication connection with the central device 12, form a new advanced network and re-determine the new main central device. When it is determined that the central device 15 receives the information that the central device 11 comes back online within the first time threshold, the central device 15 can re-establish a communication connection with the central device 11 . In this way, when the central device 11 as the main central device goes offline for a short period of time and comes online again, the steps of establishing a new advanced network can be temporarily omitted to save power consumption.

For the specific process of establishing a communication connection between the central device 15 and the central device 12 and determining a new main central device, reference can be made to the relevant description in the embodiment shown in FIG. 5A , which will not be described again in this application.

In some embodiments, if the central device 15 receives information that the central device 11 is back online before the central device 15 establishes a communication connection with the central device 12, the central device 15 gives up establishing a communication connection with the central device 12 and communicates with the central device 12. The central device 11 re-establishes the communication connection.

In some embodiments, after determining that the central device 15 is the new main central device, the central device 15 can save the network information of the newly formed advanced network. For the specific content and acquisition method of the network information of the new advanced network, please refer to the above. The relevant content in the embodiment shown in FIG. 5A will not be described again in this application.

In this way, when the main central device of the advanced network is offline, other electronic devices in the advanced network can quickly determine the new main central device and form a new advanced network to perform the services that the original advanced network needs to perform. . This can greatly reduce the service interruption time caused by the offline main center equipment, and improve the efficiency and stability of advanced network execution services.

In some embodiments, after the new advanced network is established and the main central device of the original advanced network comes online again, the new advanced network can be reorganized into the original advanced network, that is, the advanced network before the main central device went offline.

For example, after the second high-level network is reorganized into a new high-level network after the central device 11 goes offline, as shown in FIG. 6B , the specific process of reorganizing the new high-level network into a second high-level network after the central device 11 comes back online may include Following steps:

S604: The central device 11 sends the first online notification to the central device 15 and the central device 12 respectively.

After the central device 11 comes back online, the central device 11 can determine the devices that had communication connections with the central device 11 before the central device 11 went offline based on the network information of the advanced network stored before the central device 11 went offline, and send notifications to these devices (such as the central device 15 , central device 12, etc.) to send the first online notification. The first online notification may include online information, and the online information may be used to notify the device that receives the first online notification that the central device is back online, and request the device to re-establish a communication connection with the central device 11 .

In some embodiments, the first online notification may also include the connection relationship of the central device 15 or the central device 12 in the second high-level network. For example, the first online notification sent by the central device 11 to the central device 15 may include online information and the connection relationship of the central device 15 in the second high-level network. The connection relationship of the central device 15 in the second high-level network may include: central device 15 has established a communication connection with the central device 11, and the central device 15 has established a communication connection with the slave device 13. The connection relationship between the central device 15 or the central device 12 in the second high-level network can be obtained from the network information of the second high-level network saved by the central device 11 . The connection relationship of the central device 15 in the second high-level network can be used to instruct the central device 15 to disconnect communication connections other than the above-mentioned connection relationship of the central device 15 in the second high-level network.

S605, the central device 15 disconnects the communication connection from the central device 12.

S606: The central device 15 re-establishes a communication connection with the central device 11.

S607: The central device 12 re-establishes a communication connection with the central device 11.

After receiving and responding to the first online notification, the central device 15 and the central device 12 respectively re-establish communication connections with the central device 11 , and the central device 15 disconnects the communication connection with the central device 12 .

In some embodiments, after the central device 15 re-establishes the communication connection with the central device 11, the central device 15 can also send agent service data to the central device 11. The agent service data includes the central device 15 during the period when the central device 11 is offline. The data generated by the measurement service performed by the advanced network of the new main center device. The central device 11 can receive and save these agency business data.

It can be understood that if in the second advanced network, the central device 11 is also connected to a slave device, the slave device originally connected to the central device 11 receives and responds to the first online notification and can re-establish communication with the central device 11 connect. In some embodiments, if the slave device has established communication connections with other central devices (such as central device 12) while the central device 11 is offline, the slave device can disconnect after receiving the first online notification sent by the central device 11. open and middle The communication connection of the central device 12 and the communication connection with the central device 11 are re-established.

In this way, after the main central device of the original advanced network comes back online, the new advanced network can be reorganized into the original advanced network based on the network information of the original advanced network.

In a possible implementation, in addition to the main central device in the advanced network that can save the network information of the advanced network, other central devices and/or slave devices can also save the network information of the advanced network as backup. The other central devices and /or the slave device may also be called a backup device in the embodiment of this application. Taking the second advanced network in the above embodiment as an example, the specific process of data backup may include the following steps:

1. The central device 11 obtains the device detection type and device power consumption type of all central devices and slave devices in the advanced network.

Device detection types may include active detection devices (rich devices) and passive detection devices (poor devices). Among them, rich devices are devices that have the ability to actively detect other devices, and poor devices are devices that do not have the ability to actively detect other devices and can only be detected by rich devices. The central devices are all rich devices, and the slave devices can be rich devices or poor devices.

The power consumption types of equipment can include long-term power equipment and weak power equipment. Among them, long-term power equipment is an electronic device that is plugged in and has a continuous and stable power supply, while weak-current equipment is an electronic device that uses the battery in the electronic device as a power source. Therefore, compared with long-duration equipment, weak-current equipment needs to consider power consumption issues more.

The central device 11 can obtain the device detection type and device power consumption type of each device in the high-level network through the communication connection in the second high-level network. For example, the central device 11 can obtain the device detection type and device power consumption type of the central device 15 through the communication connection between the central device 11 and the central device 15 . The central device 15 can also be used as a relay, and the device detection type and device power consumption type of the slave device 13 can be obtained through the communication connection between the central device 15 and the slave device 13 and the communication connection between the central device 11 and the central device 15 .

In a possible implementation, the central device in the secondary network can actively obtain the device detection type and device power consumption type of each device in the secondary network, and combine the device detection types and device power consumption types of all devices in the secondary network. The equipment power consumption type is sent to the central device 11. This application does not specifically limit the specific acquisition steps of the equipment detection type and equipment power consumption type.

2. The central device 11 determines the backup device based on the device detection type and device power consumption type.

The central device 11 may determine one or more backup devices based on the device detection type and device power consumption type of each device in the second advanced network. Preferably, an electronic device with a detection type of rich device and a power consumption type of long-term power device can be used as a backup device. At the next level, electronic equipment with detection type rich equipment and power consumption type weak current equipment can also be used as backup equipment.

In a possible implementation, the user can also set the backup device by himself and determine the priority of the backup device. Taking the smart home scenario as an example, the selection priority of backup devices from high to low can be set to smart TVs, routers, and speakers (VUI).

3. The central device 11 sends the backup data to the backup device.

After determining the backup device, the central device 11 can send backup data to the backup device.

In the second high-level network, the backup data may include network information of the second high-level network. In some embodiments, the backup data may also include service data of the second high-level network. The service data is data generated by measurement services, distributed collaboration services, communication services and other services performed by devices in the advanced network through the advanced network. For specific content, please refer to the relevant description in the embodiment shown in Figure 8 below. This application No details will be given here.

4. The backup device saves the backup data.

In this way, by saving the backup data in the backup device, the advanced network can read the backup when the business data stored in the main center device or the network information of the advanced network cannot be read, is damaged, or the main center device unexpectedly goes offline. Backup data in the device, and ensure the normal operation of the advanced network based on the backup data (for example, perform measurement services, communication services, etc. that should be performed before unexpected situations occur).

After the main central device (central device B) of the advanced network 30 shown in FIG. 5B goes offline, the central device A and the central device C receive the first offline notification sent by the central device B. In response to the first offline notification, the central device A and central device C can use the method shown in Figure 5A to form a secondary network A0 and a secondary network C0 as shown in Figure 6C, with central device A as the main central device, central device C as the secondary central device, and multiple Each slave device is an advanced network 40 of slave devices.

As shown in FIG. 6C, the advanced network 40 may include a central device A, a central device C, and a plurality of slave devices. In the high-level network 40, the plurality of slave devices include all slave devices in the secondary network A0 and the secondary network C0. In some embodiments, multiple slave devices in the high-level network 40 may also include one or more slave devices in the secondary network B0, that is, the central device A or the central device C may temporarily take over one or more of the secondary networks B0. Multiple slave devices. Among them, the secondary network A0, the secondary network B0 and the secondary network C0. For the specific content of the above two secondary networks, please refer to the relevant content in the embodiment shown in FIG. 4B.

It should be noted that after the central device B comes back online, the advanced network 40 can reorganize the advanced network 40 into the advanced network 30 shown in FIG. 5B according to the method shown in FIG. 6B.

Figure 7A shows a schematic diagram of the reorganization process of the advanced network when one or more sub-center devices of the advanced network are offline.

The re-networking process after the secondary central device goes offline can be applied to any high-level network. The high-level network can be composed of two or more secondary networks. The following takes the first advanced network in the above embodiment as an example to describe the process of re-networking after the secondary central device (central device 12) goes offline.

As shown in Figure 7A, when the central device 12 is offline, the reorganization process of the first high-level network may include the following steps:

S701. The central device 12 sends a second offline notification to the central device 11, which is used to notify the central device 11 that the central device 12 is offline.

In the first advanced network, when the central device 12 is offline, it may send a second offline notification to the main central device (the central device 11) to notify the central device 11 that the central device 12 is offline.

In a possible implementation, when the central device 12 goes offline unexpectedly, for example, when the central device 12 suddenly loses power, fails, etc., the central device 11 (main central device) can be based on the connection between the central device 11 and the central device 12 The situation determines whether the central device 12 is offline, that is, when the communication connection between the central device 11 and the central device 12 is disconnected, the central device 11 determines that the central device 12 is offline.

S702: The central device 11 determines the isolated device based on the network information of the first high-level network.

Upon receiving and responding to the second offline notification, the central device 11 may determine one or more isolated devices based on its stored network information of the first high-level network. The one or more isolated devices refer to devices that have a connection relationship with the central device 12 in the first advanced network, such as the slave device 14 .

S703. The central device 11 sends a second networking request to the isolated device, requesting the isolated device to establish a communication connection with the central device 11.

After determining that the slave device 14 is an isolated device, the central device may send a second networking request to the slave device 14 to request the slave device 14 to establish a communication connection with the central device 11 .

S704, the central device 11 establishes a communication connection with the slave device 14.

After receiving the second networking request, the slave device 14 can establish a communication connection with the central device 11 to form the first high-level network into a new high-level network, which may also be called a third high-level network in this application.

It can be understood that, in some embodiments, when there are multiple isolated devices, the central device 11 may send second networking requests to the multiple isolated devices respectively. After receiving the second networking request, the multiple isolated devices can respectively establish communication connections with the central device 11 . Furthermore, in other embodiments, when the central device 11 determines that the number of connected electronic devices is greater than the maximum number of connectable devices of the central device 11 , the central device 11 stops establishing communication connections with other electronic devices.

In some embodiments, after the central device 11 establishes a communication connection with one or more isolated devices, the central device 11 can save the network information of the new high-level network, that is, the network information of the third high-level network.

For example, Table 8 shows the network information of the third high-level network.

Table 8 Network information of the third advanced network

As shown in Table 8, the third-level network includes three devices, whose device identifiers are U11, U13, and U14 respectively. Among them, the devices with device identifiers U11 and U13 belong to the first secondary network, and the devices with device identifiers U14 belong to the second secondary network. The device type corresponding to the device with the device identifier U11 is the master central device, and the device type corresponding to the devices with the device identifiers U13 and U14 is the slave device. Communication connections are established between the device with the device identifier U11 and the devices with the device identifiers U13 and U14 respectively. According to the network information of the third high-level network shown in Table 8, it can be seen that the first high-level network includes a first secondary network and a second secondary network. The first secondary network includes a central device 11 and a slave device 13. The device identifier of the central device 11 is U11, and the device identifier of the slave device 13 is U13. A communication connection is established between the central device 11 and the slave device 13. The second secondary network includes the slave device 14, and the central device of the second secondary network is in an abnormal state such as offline. The device identifier of the slave device 14 is U14. A communication connection is established between the central device 11 and the slave device 14 .

In this way, when the secondary central device is offline, the slave device originally connected to the secondary central device can establish a communication connection with the main central device, and the main central device takes over to maintain its normal operation in the advanced network.

In some embodiments, when the secondary central device comes back online, the new high-level network can be reorganized into the original high-level network.

Taking the new high-level network as the above-mentioned third high-level network and the original high-level network as the first high-level network as an example, as shown in Figure 7B, after the secondary central device (central device 12) comes back online, the specific process of reorganizing the high-level network may include Following steps:

S705: The central device 12 sends the second online notification to the central device 11 and the slave device 14 respectively.

After determining that the central device 12 is online, the central device 12 can determine, based on the network information of the second secondary network stored by the central device 12, the device that has established a communication connection with the central device 12 before the central device 12 goes offline (i.e., the central device 11 and the slave device 14), and sends a second online notification to the central device 11 and the slave device 14 respectively. The second online notification can be used to notify the central device 11 or the slave device 14 and the central device 12 to go online again.

S706: The central device 11 disconnects the communication connection from the slave device 14.

S707: The central device 11 and the central device 12 re-establish a communication connection.

S708, the slave device 14 re-establishes a communication connection with the central device 12.

In response to the second online notification, the central device 11 disconnects the communication connection with the slave device 14 , the central device 11 re-establishes the communication connection with the central device 12 , and the slave device 14 re-establishes the communication connection with the central device 12 .

In some embodiments, the central device 11 may delete the network information of the third high-level network (shown in Table 8) that it saves.

Using the above method, after the secondary center equipment comes back online, the new high-level network can be reorganized into the original high-level network. In this way, it is possible to avoid having too many slave devices connected to the main central device, thus reducing the amount of tasks that the central device needs to process and improving the business execution efficiency of advanced networks.

Taking the advanced network 30 shown in Figure 5B as an example, when the two sub-central devices in the advanced network 30, namely the central device A and the central device C, are both offline, the remaining electronic devices can be established based on the method shown in Figure 7A It is the advanced network 50 shown in Figure 7C.

As shown in FIG. 7C , the high-level network 50 includes a central device B and a plurality of slave devices. The plurality of slave devices may include slave devices in the secondary network B0 (for example, slave device E, slave device F, slave device G, and slave device B0). Device N) may also include one or more slave devices (for example, slave device D, slave device H, slave device L, and slave device M, etc.) in the secondary network A0 or the secondary network C0.

After the central device A of the advanced network 30 goes offline, the central device B may receive a second offline notification sent by the central device A. In response to the second offline notification, the central device B may take over the central device A connection according to the method shown in FIG. 6A One or more slave devices (for example, slave device D, slave device L, slave device M, etc.), that is, communication connections are respectively established with the one or more slave devices. Similarly, after central device C goes offline, central device B can receive a second offline notification sent by central device C. In response to the second offline notification, central device B can take over one or more slave devices connected to central device C ( For example, the slave device H) establishes a communication connection with the one or more slave devices respectively.

It should be noted that when the secondary central devices of the advanced network 30, namely central device A and central device C, come online again, the advanced network 50 can reorganize the advanced network 50 into the advanced network shown in Figure 5B according to the method shown in Figure 7B. 30.

The following describes the method and process of performing measurement services based on advanced networks.

Figure 8 shows a schematic flow chart for performing measurement services based on an advanced network.

The measurement service execution process can be applied to any high-level network, and the high-level network can be composed of two or more secondary networks. The following takes the first advanced network as an example to describe the specific process of the advanced network performing measurement services.

As shown in Figure 8, the process of performing measurement services based on advanced networks may include the following steps:

S801. The slave device 14 determines the first measurement service.

The first measurement service may include measurement content and measurement objects.

The measurement content may include any one or more of the following: ranging, angle measurement, direction finding, orientation measurement, detection of internal and external relationships between multiple electronic devices (for example, whether the slave device 14 is inside the slave device 13, etc. etc.), measure the existence relationship (for example, within the distance range of the first threshold from the slave device 14, whether there is the slave device 13, etc.).

The measurement object may be any one or more electronic devices in the first high-level network. For example, when the measurement content is ranging and the measurement object is the slave device 13 , the slave device 14 determines that the first measurement service is to measure the distance between the slave device 14 and the slave device 13 .

In some embodiments, the slave device 14 may receive and respond to a user's operation on the slave device 14 to determine the first measurement. Volume business. For example, in the multi-screen collaboration scenario shown in FIG. 2A , the display 22 may receive and respond to the user's operation of moving the window on the display 22 and determine that the first measurement service is to measure the orientation of the tablet 21 relative to the display 22 .

In other embodiments, the slave device 14 may also determine the first measurement information spontaneously. For example, an application program on the slave device 14 may spontaneously request to perform a first measurement service based on the needs of the application program running, and so on.

In a possible implementation manner, after determining the first measurement service, or while determining the first measurement service, the slave device 14 may also determine the measurement method of the first measurement service. The measurement method can be any one or more of the following: Bluetooth, ultrasonic, WLAN, IMU, UWB, etc. The measurement method can be determined based on the measurement content. For example, when the measurement content is angle measurement, the measurement method is IMU. In some embodiments, the measurement method can also be determined based on the measurement device on the slave device 14. For example, when the slave device 14 only has a Bluetooth module, the measurement method can be Bluetooth. In other embodiments, the measurement method may also be determined by the central device 12 or the central device 11 .

It can be understood that other slave devices or central devices in the first high-level network can also determine the first measurement service. Here, only the determination of the first measurement service by the slave device 14 is used as an example. This application will not do this here. limited.

S802: The slave device 14 sends a first measurement request to the central device 11 through the central device 12, to request the central device 11 to allow the slave device 14 to perform the first measurement service.

After determining the first measurement service, the slave device 14 may send a first measurement request to the central device 11 (main central device) based on the first advanced network using the central device 12 as a relay, requesting the central device 11 to allow the slave device 14 to perform the first measurement service. 1. Measurement business.

The first measurement request may include the first measurement service and the device identification of the slave device 14 . The device identification of the slave device 14 may be used to identify the slave device 14, and the device identification may include any of the following: a device name, a media access control MAC address, and an Internet Protocol IP address.

In some embodiments, the first measurement request may also include a measurement device from the device 14, and the measurement device may include any one or more of the following: a Bluetooth module, an ultrasonic module, an IMU device, a UWB device, a WLAN module, and so on. The measurement device of the slave device 14 may be used to determine which measurement method the slave device 14 uses to perform the first measurement service.

In other embodiments, after the high-level network is established, the measurement devices of the slave devices 14 may be stored in the central device 12 (sub-master central device) and/or the central device 11 (primary central device). Therefore, after the slave device 14 determines the first measurement service, there is no need to send the measurement device of the slave device 14 to the central device 12 .

S803: The central device 11 determines whether to allow the first measurement request based on the service data of the first high-level network.

After receiving the first measurement request, the central device 11 may determine whether to allow the first measurement request based on the service data of the first advanced network.

The service data of the first high-level network may include measurement data of the first high-level network and/or to-be-executed services of the first high-level network. The measurement data of the first high-level network includes data generated by all measurement services that have been performed in the first high-level network, and the services to be performed in the first high-level network include all measurement services to be performed in the first high-level network.

For example, Table 9 shows the measurement data of a first high-level network, and Table 10 shows the services to be performed on a first high-level network.

Table 9 Measurement data of the first advanced network

As shown in Table 9, the measurement data of the first advanced network may include measurement services and measurement results. The measurement service is a measurement service that has been performed in the first advanced network, and the measurement result is a measurement result corresponding to the above-mentioned measurement service. The measurement services may include: the distance between the slave device 14 and the central device 11 , the azimuth relationship between the slave device 13 and the central device 12 , the internal and external relationship between the central device 12 and the central device 11 , the distance between the slave device 13 and the central device 12 , the distance between the slave device 13 and the central device 12 , the distance between the slave device 13 and the central device 12 The directional distance from the central device 11. The corresponding measurement results of these measurement services are: 3 meters, the slave device 13 is on the right side of the central device 12, the central device 12 is outside the central device 11, 5 meters, the slave device 13 is on 2 meters to the left of central equipment 11. According to Table 9, in the first advanced network, the distance between the slave device 14 and the central device 11 is 3 meters, the slave device 13 is on the right side of the central device 12, the central device 12 is outside the central device 11, and the slave device 13 is The distance between the central device 12 and the slave device 13 is 2 meters to the left of the central device 11 .

It can be understood that the measurement data of the first high-level network shown in Table 9 is just an example, and may also include more, less, or different measurement services and measurement results, which is not limited in this application.

Table 10: To-be-executed services of the first advanced network

As shown in Table 10, the measurement data of the first advanced network may include measurement services and measurement results. The measurement service is a measurement service for which the corresponding measurement request has been permitted in the first advanced network but the measurement result has not yet been received. The execution status may include: executing and not executing. The measurement services may include: the directional distance between the slave device 13 and the central device 11, and the azimuth relationship between the central device 12 and the slave device 14. The processing results corresponding to these two measurement services are: executing and not executing respectively. According to Table 10, it can be seen that in the first advanced network, the central device 11 has approved the measurement request for the measurement service "Measure the directional distance between the slave device 13 and the central device 11", and the central device 11 has performed the measurement request through the first advanced network. The device of the measurement service has sent a measurement license, but has not yet received the measurement results of the measurement service. The central device 11 has approved the measurement request for the measurement service "measuring the orientation relationship between the central device 12 and the slave device 14", but has not yet sent the measurement permission to the device performing the measurement service through the first advanced network.

It can be understood that the to-be-executed services of the first high-level network shown in Table 10 are just an example, and may also include more, less, or different measurement services and execution states, which are not limited in this application.

In a possible implementation, when the central device 11 can determine the measurement result of the first measurement service based on the service data of the first high-level network, the central device 11 determines to allow the slave device 14 to perform the first measurement service. When the central device 11 cannot determine the measurement result of the first measurement service based on the service data of the first advanced network, the central device 11 determines that the slave device 14 is not allowed to perform the first measurement service.

When the service data of the first advanced network meets the following conditions, the central device 11 can determine the measurement result of the first measurement service based on the service data of the first advanced network.

Scenario 1: The measurement service in the service data of the first advanced network includes the first measurement service.

Take the service data of the first advanced network including the measurement data of the first advanced network shown in Table 9 as an example:

When the measurement service in Table 9 includes the first measurement service, the central device 11 can based on the measurement service corresponding to the measurement service. The measurement result determines the measurement result of the first measurement service. For example, when the first measurement service is to measure the distance between the slave device 14 and the central device 11, the central device 11 can determine based on the service data of the first advanced network that the measurement result of the first measurement service is: the slave device 14 and the central device 11 The distance is 3 meters.

Take the service data of the first high-level network including the to-be-executed services of the first high-level network shown in Table 10 as an example:

When the measurement services in Table 10 include the first measurement service, the central device 11 may determine the measurement results of the first measurement service based on the measurement results corresponding to the measurement services. For example, when the first measurement service is to measure the directional distance between the slave device 13 and the central device 11, the central device 11 may complete the execution of the currently executing measurement service "Measure the directional distance between the slave device 13 and the central device 11", and After receiving the measurement result of the measurement service, the central device 11 determines the measurement result of the first measurement service. That is, the central device 11 can determine the measurement result of the first measurement service based on the measurement result reported to the central device 11 after the service to be executed is completed.

Scenario 2: The measurement results of the first measurement service can be deduced based on the measurement results corresponding to one or more measurement services in the service data of the first advanced network.

For example, when the first measurement service is "Measuring the directional distance between the slave device 13 and the central device 12", according to the measurement data of the first advanced network shown in Table 9, it can be seen that the slave device 13 is on the right side of the central device 12, And the distance between the slave device 13 and the central device 12 is 5 meters. In this case, it can be determined from the above two measurement results that the measurement result of the first measurement service is "the slave device 13 is 5 meters to the right of the central device 12".

For another example, when the first measurement service is "Measuring the distance between the central device 11 and the central device 12", according to the measurement data of the first advanced network shown in Table 9, it can be seen that the slave device 13 is on the right side of the central device 12, and The distance between the slave device 13 and the central device 12 is 5 meters, and the slave device 13 is 2 meters to the left of the central device 11 . In this case, it can be determined from the above three measurement results that "the central device 11 is 7 meters to the right of the central device 12", that is, the measurement result of the first measurement service is "the distance between the slave device 13 and the central device 12 is 7 meters".

Similarly, take the service data of the first advanced network including the to-be-executed services of the first advanced network shown in Table 10 as an example:

For example, when the first measurement service is "Measuring the directional distance between the slave device 13 and the central device 11", according to the to-be-executed services of the first advanced network shown in Table 10, the measurement service being executed includes "Measuring the slave device 13" 13 and the directional distance from the central device 11". The distance between the slave device 13 and the central device 11 can be determined based on the directional distance between the slave device 13 and the central device 11 . That is, after the measurement service being executed is completed and the measurement results are reported to the central device 11 , the central device 11 can determine the measurement results of the first measurement service.

For another example, when the first measurement service is "Measuring the azimuth relationship between the slave device 14 and the central device 12", according to the to-be-executed services of the first advanced network shown in Table 10, the central device 11 has permitted the measurement service "Measurement Center" Measurement request corresponding to the "azimuth relationship between device 12 and slave device 14". Furthermore, based on the orientation relationship between the central device 12 and the slave device 14, the orientation relationship between the measurement slave device 14 and the central device 12 can be determined. That is, after the measurement service is completed and the measurement results are reported to the central device 11, the central device 11 can determine the measurement results of the first measurement service.

It should be noted that these are just some examples. When the first measurement service is angle measurement, measurement of internal and external relations, measurement of orientation, etc., it can also be determined in the same or similar manner as in the above embodiment whether it can be based on the first high-level measurement. The service data of the network determines the measurement result of the first measurement service.

In this way, when the measurement result of the first measurement service can be determined based on the service data of the first advanced network, the central device 11 can determine that the slave device 14 is not allowed to perform the first measurement service, thereby reducing the execution of unnecessary services, thereby reducing the cost of the first measurement service. power consumption.

In some embodiments, the measurement data in the network information of the first high-level network may also include a storage time.

For example, Table 11 shows the measurement data of another first high-level network.

Table 11 Measurement data of the first advanced network

As shown in Table 11, the measurement data of the first advanced network may include measurement services, measurement results and storage time. The measurement service may be a measurement service that has been performed in the first advanced network. The measurement result is the measurement result corresponding to the above-mentioned measurement service, and the storage time can be used to indicate the time for the central device 11 to save the measurement result corresponding to the measurement service. According to the measurement data of the first advanced network shown in Table 11, in the first advanced network, the storage time of the data "the distance between the slave device 14 and the central device 11 is 3 meters" is 10:00, and "the distance between the slave device 14 and the central device 11 is 3 meters". 13 is on the right side of the central device 12" The saving time of this data is 08:45, the saving time of this data "the central device 12 is outside the central device 11" is 09:54, "the slave device 13 and the central device 12 The distance is 5 meters" The data is saved at 10:02, and the data "Slave device 13 is 2 meters to the left of the central device 11" is saved at 07:59.

When the central device 11 determines that the measurement result of the first measurement service can be determined based on one or more service data in the first advanced network's service data, the central device 11 also needs to determine the measurement result of the first measurement service based on the one or more service data. The storage time determines whether the one or more business data is valid. When the interval between the storage time of one or more items of service data used to determine the measurement results of the first measurement service and the current time in the first advanced network is less than the second time threshold, the central device 11 determines that the item or items of service data are If the service data is valid, the central device 11 determines that the measurement result of the first measurement service can be determined based on the service data of the first advanced network. When, in the first advanced network, the interval between the storage time of one or more service data used to determine the measurement results of the first measurement service and the current time is greater than or equal to the second time threshold, the central device 11 determines that the one or more If the service data is invalid, the central device 11 cannot determine the measurement result of the first measurement service based on the service data of the first advanced network.

In this way, when the device in the advanced network is in a mobile state, it can be determined based on the storage time of the service data of the advanced network whether the service data is valid, so as to avoid invalid service data affecting the execution of the measurement service.

In some embodiments, the main central device (central device 11) and the secondary main central device (central device 12) in the first advanced network can periodically detect whether the locations of the central devices and slave devices connected to them have changed. When it is discovered that the location of a device has changed, the central device 11 promptly deletes the service data related to the device in the first advanced network from the network information of the first advanced network.

In this way, when the electronic equipment in the advanced network is in a mobile state, invalid service data can be deleted in time to avoid invalid service data affecting the execution of the measurement service.

When the central device 11 cannot determine the measurement result of the first measurement service based on the service data of the first advanced network, the central device 11 determines to allow the first measurement request. At this time, the central device 11 may perform the following steps S804 to S807.

When the central device 11 can determine the measurement result of the first measurement service based on the service data of the first advanced network, the central device 11 determines to reject the first measurement request. At this time, the central device 11 executes the following step S808.

In some embodiments, when the measurement method of the first measurement service is ultrasonic wave, if and only if the central device 11 determines that the measurement service being executed in the first advanced network does not include a measurement method using ultrasonic wave, the central device 11 may determine The first measurement request is allowed. Otherwise, the central device 11 can reject the first measurement request and send a rejection notification to the slave device 14 through the first advanced network, notifying the slave device 14 that the execution of the first measurement service is not allowed.

In a possible implementation, when the central device 11 determines that there is an ongoing measurement service using the ultrasonic measurement method in the first advanced network, the central device 11 may, after determining that the ongoing measurement service has ended, permit the first A measurement request. In this way, interference to the measurement results caused by multiple devices emitting ultrasonic waves at the same time can be avoided.

S804: The central device 11 sends the first measurement permission to the slave device 14 through the central device 12, which is used to notify the slave device 14 to allow the slave device 14 to perform the first measurement service.

When the central device 11 determines that the slave device 14 is allowed to perform the first measurement service, the central device 11 may send the first measurement permission to the slave device 14 through the central device 12 . That is, the central device 11 may first send the first measurement permission to the central device 12, and the central device 12 receives and sends the first measurement permission to the slave device 14.

In some embodiments, the first measurement permission may include permission information and a device identification of the measurement object. Taking the measurement object as the slave device 13 as an example (in the embodiments of this application, the measurement object is the slave device 13 as an example), the first measurement permission includes license information and the device identification of the slave device 13 . The permission information is used to notify the slave device 14 that the first measurement service can be performed. The device identification of the slave device 13 is used to identify the slave device 13 during subsequent execution of the first measurement service.

In other embodiments, the first measurement permission may also include a measurement mode. When the first measurement request sent by the slave device 14 does not include the measurement method, the central device 11 may be based on the measurement device of the slave device 14 (the initiator of the first measurement request) and the slave device 13 (the measurement object of the first measurement request). The measurement device determines the measurement method of the first measurement service. For example, when the measurement device of the slave device 14 and the measurement device of the slave device 13 both include Bluetooth modules, the central device 11 may determine that the measurement mode of the first measurement service is Bluetooth. In some embodiments, the central device 11 may also determine the measurement method based on the first measurement service. For example, when the first measurement service is angle measurement, the central device 11 determines that the measurement method of the first measurement service is measurement using an IMU device. It should be noted that, as the main central device of the first high-level network, the central device 11 can obtain the measurement devices of the slave device 14 and the measurement devices of the slave device 13 through the first high-level network.

In some embodiments, when the central device 11 determines that the slave device 14 is allowed to perform the first measurement service, optionally, the central device 11 may send a first measurement notification to the measurement object (for example, the slave device 13), notifying the slave device 13 to be The measurement object of the first measurement business. The first measurement notification may also include the measurement method of the first measurement service. The slave device 13 receives and responds to the first measurement notification and may perform auxiliary operations based on the measurement method to cooperate with the slave device 14 in performing the first measurement service.

For example, when the measurement method of the first measurement service is Bluetooth, the slave device 13 receives and responds to the first measurement notification, can turn on Bluetooth of the slave device 13, and transmit a Bluetooth signal.

For another example, when the measurement mode of the first measurement service is ultrasonic wave, the slave device 13 receives and responds to the first measurement notification and determines a specific waveform as the device identifier of the slave device 13 for use after receiving the ultrasonic wave emitted by the slave device 14 , transmitting this specific waveform so that the echo reflected from the device 13 is recognized by the slave device 14, and so on.

S805: The slave device 14 performs the first measurement service.

The slave device 14 receives and responds to the first measurement permission and performs the first measurement service.

Taking the first measurement service as an example of measuring the distance between the slave device 14 and the slave device 13, the slave device 14 receives the first measurement After the quantity is allowed, the first measurement service can be executed based on the measurement mode and the device identification of the slave device 13 . The measurement method may be determined by the device 14 (refer to step S801), or may be obtained from the first measurement permission (refer to step S807).

For example, when the measurement mode is Bluetooth, the slave device 14 may receive and respond to the first measurement permission, determine the strength of the Bluetooth signal transmitted by the slave device 13 received by the slave device 14 based on the device identification of the slave device 13, and determine the strength of the Bluetooth signal transmitted by the slave device 13 based on the slave device 14. The strength of the Bluetooth signal transmitted from device 13 received by device 14 determines the distance between slave device 14 and slave device 13 . The specific determination method can refer to the following formula (2):

In the above formula (2), d represents the distance to be measured (in meters), RSSI represents the received Bluetooth signal strength, A represents the Bluetooth signal strength when the transmitter and receiver are one meter apart, and n represents the environmental attenuation factor. When the application scenario is determined, the values of A and n are determined and can be regarded as constants. Then according to the above formula (2), the distance between the slave device 14 and the slave device 13 can be determined based on the strength of the Bluetooth signal transmitted from the slave device 13 received by the slave device 14 .

It can be understood that when the measurement method is WLAN or other other methods, the distance between the slave device 14 and the slave device 13 can also be determined based on the strength of the signal transmitted from the slave device 13 received by the slave device 14 . When the measurement mode is ultrasonic waves, the slave device 14 can emit ultrasonic waves, receive echoes reflected from the slave device 13 , and determine the distance between the slave device 14 and the slave device 13 based on the time of transmitting and receiving the echoes. In addition, when the first measurement service is a service such as measuring the angle, orientation, or internal and external relationship between the slave device 14 and the slave device 13, the slave device 14 can also perform the first measurement service based on an IMU device, a UWB device, or an ultrasonic module, and The measurement result of the first measurement service is determined through algorithms such as angle measurement, direction finding, and ranging. This application will not go into details here.

S806: The slave device 14 sends the measurement result of the first measurement service to the central device 11 through the central device 12.

After performing the first measurement service, the slave device 14 may send the measurement result of the first measurement service to the central device 11 through the first advanced network, that is, the slave device 14 sends the measurement result of the first measurement service to the central device 12, and the central device 12 Receive and send the measurement result of the first measurement service to the central device 11 .

Taking the first measurement service as measuring the distance between the slave device 14 and the slave device 13 as an example, the measurement result of the first measurement service may be "the distance between the slave device 14 and the central device 13 is 5 meters." For another example, in the multi-screen collaboration scenario shown in FIG. 2A to FIG. 2B , the measurement result of the first measurement service may be "tablet 21 is on the left side of display 22", or "tablet 21 is above display 22" ,etc. For another example, in the vehicle scenarios shown in FIG. 2C and FIG. 2D , the measurement result of the first measurement service may be "the mobile phone 32 is inside the car 31" or "the mobile phone 32 is outside the car 31", and so on.

In some embodiments, during the process of sending the measurement result of the first measurement service from the device 14 to the central device 11 through the central device 12, the central device 12 may, after receiving the measurement result of the first measurement service, transfer the first measurement result to the central device 11. The measurement results of the service are stored in the service data of the secondary network. The service data of the second secondary network may include measurement data of the second secondary network and/or to-be-executed services of the second secondary network, where the measurement data of the second secondary network includes all completed services in the second secondary network. The data generated by the executed measurement service, the to-be-executed services of the second secondary network include all the to-be-executed measurement services in the second secondary network. The specific content of the service data of the second secondary network can be compared with the content of the service data of the first high-level network, and will not be described again here.

S807: The central device 11 saves the measurement result of the first measurement service.

The central device 11 receives the measurement result of the first measurement service and saves the measurement result of the first measurement service to the first highest level. level network business data.

In some embodiments, when the service data of the first high-level network stored by the central device 11 includes the same measurement data as the first measurement service, that is, when the central device 11 stores the previous measurement results of the first measurement service, the center The device 11 updates the service data of the first advanced network and replaces the previous measurement result of the first measurement service with the latest measurement result of the first measurement service.

In this way, the business data of the advanced network stored in the main center device can be updated in time to avoid affecting the execution of the measurement service due to the failure of the service data stored in the main center device.

S808: The central device 11 sends the measurement result of the first measurement service to the slave device 14 through the central device 12.

When the central device 11 can determine the measurement result of the first measurement service based on the service data of the first advanced network, the central device 11 determines to send the measurement result of the first measurement service to the slave device 14 using the central device 12 as a relay. The measurement result of the first measurement service may also be used to indicate that the slave device 14 does not perform the first measurement service.

Using the above method, measurement services can be performed based on advanced networks. In addition, the main center device determines whether to execute the first measurement service, which not only avoids unnecessary measurement services and reduces power consumption, but also avoids conflicts that may occur during the execution of different measurement services, thereby avoiding affecting the measurement results.

In a possible implementation, when the secondary central device receives the first measurement request sent from the slave device and determines based on the first measurement request that the measurement object of the first measurement service belongs to the secondary network where the secondary central device is located , the secondary center device may determine whether to allow the slave device to perform the first measurement service based on the service data of the secondary network. For the specific determination method, reference may be made to the relevant content in the embodiment shown in FIG. 8 , which will not be described again in this application. After the first measurement service is executed, the slave device may send the measurement result of the first measurement service to the secondary central device, and the secondary central device receives and saves the measurement result of the first measurement service. In addition, the secondary center device can also send the measurement results of the first measurement service to the main center device of the advanced network, and the main center device can also receive and save the measurement results of the first measurement service.

Using the above method, the secondary central device determines whether the measurement service in the secondary network where it is located needs to be executed, which can greatly reduce the task load of the central device, and the measurement request can receive faster feedback, thereby improving the execution efficiency of the measurement service.

It should be noted that when the measurement mode of the first measurement service is ultrasonic, even if the secondary central device determines that the measurement object of the first measurement request it receives is an electronic device in the same secondary network, the secondary central device still needs to A first measurement request is sent to the central device to determine that there is no interference from other measurement services using ultrasonic waves during the execution of the first measurement service.

In a possible implementation, when the device that initiates the first measurement service cannot perform the first measurement service (for example, lacks a corresponding measurement device, etc.), the device that initiates the first measurement service can report to the main center of the advanced network The device sends a first measurement result request, which is used to request the main center device to determine and send the measurement result of the first measurement service to the device. It should be noted that the main center device may determine the measurement result of the first measurement service based on the service data of the advanced network and send the measurement result of the first measurement service to the device. When the main center device cannot determine the measurement result of the first measurement service based on the service data of the advanced network, the main center device can determine to add one or more measurement services to the to-be-executed service, based on the one or more measurement services. The measurement results can be deduced from the measurement results of the first measurement service. After the execution of the one or more measurement services is completed, the main center device may determine the measurement results of the first measurement service based on the measurement results of the one or more measurement services, and send a third measurement result to the device that initiated the first measurement service. 1. Measurement results of measurement services.

In a possible implementation, the backup device in the above embodiment can not only back up the network information of the advanced network, but also information, and can also back up business data of advanced networks. For example, the central device of the advanced network may periodically send the service data of the advanced network and/or the network information of the advanced network to one or more backup devices. For the way in which the central device of the advanced network determines the backup device, reference can be made to the relevant content in the foregoing embodiments, which will not be described again in this application.

In this way, by saving backup data in the backup device, the advanced network can read the backup device when the business data stored in the central device or the network information of the advanced network cannot be read, is damaged, or the central device goes offline unexpectedly. backup data, and based on the backup data to ensure the normal operation of the advanced network (for example, performing measurement services, communication services, etc. that should be performed before unexpected situations occur).

It should be noted that in some embodiments, after the slave device 14 determines that the cooperative device is the central device 11, the slave device 14 also needs to determine the orientation relationship between the central device 11 and the slave device 14 (for example, as shown in Figures 2A and 2B Multi-screen collaboration scenario, etc.), or determine the distance between the central device 11 and the slave device 14 (such as the distributed collaboration scenario shown in Figure 2E and Figure 2F, etc.). That is, when the slave device 14 determines that the cooperative device is the central device 11 , it can determine that the first measurement service of the slave device 14 is to measure the orientation relationship or distance between the slave device 14 and the central device 11 . in. For the specific process of executing the first measurement service, reference can be made to the embodiment shown in FIG. 8 , which will not be described again in this application.

S902: The slave device 14 sends a distributed collaboration relationship establishment request to the central device 11.

After determining that the cooperative device is the central device 11, the slave device 11 can send a distributed collaboration relationship establishment request to the central device 11 through the first advanced network, using the central device 12 as a relay, for requesting the central device 11 and the slave device 14 Establish distributed collaborative relationships.

S903: The central device 11 establishes a distributed collaboration relationship with the slave device 14.

S904: The slave device 14 receives and responds to the user's first operation on the slave device 14, and sends a first collaboration request to the central device 11 to request the central device 11 to perform a second operation.

After the distributed collaboration relationship is established, the slave device 14 may receive and respond to the user's first operation on the slave device 14 and send a first collaboration request to the central device 11 through the first advanced network. The first collaboration request is used to instruct the center. The device 11 performs the second operation.

Computer 42 display operation The text of the guide, etc.

S905, the central device 11 performs the second operation.
