Description

Technical Field

[0001] The present invention relates to the field of intelligent wearable devices, and in particular to a method for enhancing the communication stability of self-organizing network team communication devices by using a mobile phone. Background Art

[0002] Although existing Bluetooth Mesh-based self-organizing network devices can communicate in teams without mobile devices, in scenarios with good mobile network such as urban areas, the communication effect will be greatly reduced due to the high interference in the 2.4G frequency band.

[0003] The common solutions currently available all have shortcomings: Increasing the transmission power can ensure that the signal propagates farther and is more resistant to interference, but there are many problems. On the one hand, increasing the transmission power means higher energy consumption; on the other hand, the domestic SRRC certification and the foreign FCC and CE certifications all limit the upper limit of the power spectrum density. In addition, the source of interference is the high density of 2.4G devices in the same space. Increasing the power will also affect the effects of other Bluetooth, WiFi and other devices.

[0004] Adding 5G or WiFi modules and optimizing communication effects through TCP / IP protocol is a feasible overall solution, but there is a problem of high logic complexity within the chip. The analog audio signals transmitted by Bluetooth and the digital audio signals transmitted by TCP / IP network need to be decoded and de-duplicated to avoid echo interference. At the same time, the complex firmware logic leads to increased energy consumption, which is not suitable for wearable devices that pursue lightweight.

[0005] A pure Internet solution develops similar conference software with voice group chat function, and connects calls through ordinary Bluetooth headsets. It is not feasible in areas with poor mobile network signals, and outdoor scenes will be greatly limited.

[0006] Therefore, it is necessary to provide a method for using a mobile phone to enhance the communication stability of self-organizing network team communication equipment to solve the above technical problems. Summary of the invention

[0007] The present invention provides a method for enhancing the communication stability of self-organizing network team communication devices by using mobile phones, which solves the problem that the communication effect of self-organizing network devices based on Bluetooth Mesh in urban areas and other scenarios is poor. The existing solutions have serious defects. Increasing the transmission power faces the problems of high energy consumption, authentication restrictions, and interference with other devices. Adding 5G or WiFi modules will make the chip and firmware logic complicated and increase energy consumption. It is not suitable for lightweight wearable devices. Pure Internet solutions are severely limited in poor mobile phone signals and outdoor scenarios.

[0008] In order to solve the above technical problems, the present invention provides a method for enhancing the communication stability of a self-organizing network team communication device by using a mobile phone, comprising the following steps: S1. Build a network topology to form a logical concept network composed of a hard Mesh and a soft Mesh. The hard Mesh is completed by BLE chips with Mesh protocols to achieve point-to-point connection, transmission, or relay transmission of audio between devices. The soft Mesh is implemented through a mobile phone App as a backup connection supplement solution when the hard Mesh signal is poor. S2. Determine the communication logic to ensure that there is exactly one voice path between every two people at a certain time point. Report the team formation situation to the background through the mobile phone. The background analyzes the connection information, plans small groups, and designates a unique soft Mesh routing node (R). The routing table is sent back to the device to block duplicate sounds. The transmission method combines APP + Mesh communication. S3. Design a hardware solution so that the Bluetooth chip and the Mesh chip are connected through two paths: data through UART and audio through I2S. The Bluetooth chip serves as the main control chip, responsible for connecting to the mobile phone and coordinating multiple audio paths to achieve functions such as listening to music, Mesh voice collection, Mesh voice transmission, and making calls. A specific voice transmission path is added when the soft Mesh is implemented.

[0009] Preferably, the team formation method of the hard Mesh in S1 is that several devices enter the team formation state or perform a predefined action, sense each other, and agree on the same channel and team formation number for communication. After the team formation is completed, devices with close distances and the same team formation number can communicate with each other, and the network dynamically forms a network. The node routing table is dynamically updated according to the device connection status.

[0010] Preferably, when the soft Mesh network device forms a team, it records the list of all nodes in the current team and synchronizes it to the mobile phone. The list will no longer change after the team formation is completed. The server records the current status of each user in the group. There is at most one soft Mesh routing node (R) in a hard Mesh group, and the selection logic is determined in the background service.

[0011] Preferably, the mixing logic is as follows: When an ordinary node (c) listens, if there is a routing table and (R) is in the table, it notifies the mesh chip to allow through the hard mesh nodes and dropped nodes according to the whitelist. If there is no routing table, it allows through all sounds. When an ordinary node (c) speaks, it transmits the mic sound to the mesh chip. If it is itself (R), it mixes the filtered sound with the mic and transmits it to the mobile phone Bluetooth APP. At the same time, it mixes the APP sound received by the mobile phone Bluetooth with the mic and transmits it to the mesh chip. If it is itself a hard Mesh routing node (r), it forwards all sounds according to the original logic of the mesh chip without passing through the MCU and without filtering.

[0012] Preferably, the routing table receiving rule is as follows: the update timing is for the APP or (R) to actively synchronize, and (r)(c) to periodically query and update; (R) synchronizes the routing table of its own subnet from the APP, and then broadcasts the latest routing table from the Mesh; (r)(c) has an initial routing table during team formation and dynamically updates it during the process. If connected to the APP, it is processed according to the APP synchronization method. If not connected to a mobile phone or other devices, it determines whether to accept the routing table of the hard Mesh synchronization according to the connection status of (R) in the routing table. If (R) in its own routing table is not connectable or there is no (R), it accepts the routing tables sent by other nodes in the group and retains the part belonging to itself.

[0013] Preferably, when the hard Mesh team formation situation changes, it depends on the status sensing ability of the Mesh chip. When the Mesh chip senses a change in the hard Mes node or hard routing node (r), it immediately notifies the MCU chip, including synchronizing the hard mesh routing table to the APP mobile phone in real time during the team formation process, determining that the group list relied on by the soft Mesh no longer changes after team formation but the hard Mesh status change information is still synchronized to the APP side, and operations such as node connection or disconnection, turning off the Mesh or re-pairing, and re-opening the Mesh are all notified to the APP and corresponding processing is carried out.

[0014] Preferably, the APP logic includes having a user system and binding it to the device ID, establishing a group during team formation to determine the list of group members, i.e., the routing table, freezing when there is no one online in the group, dissolving or deleting it if not used for a long time, and creating a real-time voice call connection only when all (R) nodes are online.

[0015] Preferably, the background logic includes managing users, group relationships, and group status, calculating the routing table, building a group and obtaining all routing tables through the APP every time there is a change in the hard Mesh routing, calculating the connectivity relationship, hard Mesh grouping and selecting (R) nodes, calculating the soft routing table of each node and sending it down, and the calculation and sending timing is when there is a change in the hard Mesh routing information or when the device routing table information update has not been returned after 10 seconds.

[0016] Preferably, in the hard mesh networking scenario, multiple people use the Mesh networking function of the device to complete team formation, and at least one person confirms the completion of team formation on the mobile phone APP. At this time, the routing table list is confirmed. If there is a mobile phone APP online in the team, there is no need to transmit voice information through the mobile phone APP when the hard Mesh interconnection is normal.

[0017] Preferably, when the hard Mesh experiences situations such as disconnection, splitting, node movement, and merging, the soft Mesh is used to increase the amplitude, adjust the routing table and the voice transmission path to ensure that all nodes can still hear the voices of other nodes and maintain communication stability.

[0018] Compared with the related art, the method provided by the present invention for enhancing the communication stability of self-organizing network team communication equipment by using a mobile phone has the following beneficial effects: The present invention provides a method for enhancing the communication stability of a communication device in a self-organizing network team by using a mobile phone. On the basis of not adding other devices, a low coupling and low power consumption solution is adopted to achieve the purpose of enhancing the communication stability, which is advanced in the industry. Bluetooth Mesh devices usually have functions such as connecting to mobile phones to listen to music. This solution realizes the "second network" through APP and reasonably utilizes the capabilities of existing surrounding devices; By controlling the routing table, the sound of a single node is prevented from appearing in two networks at the same time, thus achieving low coupling between the two networks; The routing table algorithm is executed on the background server, freeing up terminal computing power and reducing the complexity of distributed computing; No additional algorithms are added to the device side, and chips with too much computing power are not required, providing an optional solution for lighter wearable devices.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Please refer to Figure 1 and Figure 2 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of a method for enhancing the communication stability of a self-organizing network team communication device using a mobile phone provided by the present invention; Figure 2 A method for enhancing the communication stability of a self-organizing network team communication device using a mobile phone comprises the following steps: S1. Build network topology to form a logical network consisting of hard Mesh and soft Mesh. The hard Mesh is completed by a BLE chip with Mesh protocol to achieve point-to-point connection, transmission or relay transmission of audio between devices; the soft Mesh is implemented through a mobile phone app as a backup connection supplementary solution when the hard Mesh signal is poor; S2. Determine the communication logic to ensure that there is only one voice channel between two people at a time. Report the team situation to the background through the mobile phone. The background analyzes the Unicom information to plan a small group and designate a unique soft Mesh routing node (R). The routing table is transmitted back to the device to block repeated sounds. The transmission method adopts a combination of APP+Mesh communication. S3. Design the hardware solution so that the Bluetooth chip and the Mesh chip are connected through two paths: data transmission via UART and audio transmission via I2S. The Bluetooth chip serves as the main control chip, responsible for connecting to the mobile phone and coordinating multiple audio channels to achieve functions such as listening to music, Mesh voice reception, Mesh voice transmission, and making phone calls. When implementing the soft Mesh, a specific voice transmission path is added.

[0022] The teaming method of the hard Mesh in S1 is as follows: several devices enter the teaming state or perform agreed actions, sense each other and agree on the same channel and teaming number for communication. After the teaming is completed, devices with close proximity and the same teaming number can communicate with each other, and the network dynamically forms a network, and the node routing table is dynamically updated according to the device connection status.

[0023] When the soft Mesh network device in S1 establishes a team, it records the list of all nodes in the current team and synchronizes it to the mobile phone. After the teaming is completed, the list no longer changes. The server records the current status of each user in the group. There is at most one soft Mesh routing node (R) in a hard Mesh group, and the selection logic is determined in the background service.

[0024] The mixing logic is as follows: When the ordinary node (c) is listening, if there is a routing table and (R) is in the table, it notifies the mesh chip to allow the hard mesh node and the dropped node to pass through according to the white list. If there is no routing table, all sounds are allowed to pass through; When the ordinary node (c) is speaking, it transmits the mic sound to the mesh chip; If it is itself (R), it mixes the filtered sound with the mic and transmits it to the mobile phone Bluetooth APP, and at the same time mixes the APP sound received by the mobile phone Bluetooth with the mic and transmits it to the mesh chip; If it is itself a hard Mesh routing node (r), it forwards all sounds according to the original logic of the mesh chip, without passing through the MCU and without filtering.

[0025] The routing table receiving rule is: The update timing is when the APP or (R) takes the initiative to synchronize, and (r)(c) query and update regularly; (R) synchronizes the routing table of its own subnet from the APP, and then broadcasts the latest routing table from the Mesh; (r)(c) has an initial routing table during teaming and updates it dynamically during the process. If it is connected to the APP, it is processed according to the APP synchronization method. If it is not connected to the mobile phone or other situations, it decides whether to accept the routing table synchronized by the hard Mesh according to the connection status of (R) in the routing table. If the (R) in its own routing table is not connectable or there is no (R), it accepts the routing table sent by other nodes in the group and retains the part belonging to itself.

[0026] When the hard Mesh teaming situation changes, relying on the status awareness ability of the Mesh chip, the Mesh chip senses the changes of hard Mes nodes or hard routing nodes (r), and immediately notifies the MCU chip, including synchronizing the hard mesh routing table to the APP mobile phone in real time during the teaming process, determining that the group list relied on by the soft Mesh no longer changes after teaming, but the hard Mesh status change information is still synchronized to the APP side. Operations such as node connection or disconnection, turning off Mesh or re-pairing, and reopening Mesh are all notified to the APP and corresponding processing is performed.

[0027] The APP logic includes having a user system and binding to the device ID. When teaming up, a group is established to determine the list of members in the group, that is, the routing table. When there is no one online in the group, it is frozen. If it is not used for a long time, it is dissolved or deleted. Creating a real-time voice call connection only requires all (R) nodes to be online.

[0028] The background logic includes managing users, group relationships, and group status, calculating the routing table, creating a group, and obtaining all routing tables through the APP every time the hard Mesh routing changes, calculating the connectivity relationship, hard Mesh grouping, and selecting (R) nodes, calculating the soft routing table of each node and sending it down. The calculation and sending time is when the hard Mesh routing information changes or when the device routing table information update has not been returned after 10 seconds.

[0029] In the hard mesh networking scenario, multiple people use the Mesh networking function of the device to complete teaming up, and at least one person confirms the completion of teaming up on the mobile phone APP. At this time, the routing table list is confirmed. If there is a mobile phone APP online in the team, when the hard Mesh interconnection is normal, there is no need to transmit voice information through the mobile phone APP.

[0030] When the hard Mesh experiences situations such as disconnection, splitting, node movement, and merging, the soft Mesh is used to increase the amplitude, adjust the routing table, and the voice transmission path to ensure that all nodes can still hear the voices of other nodes and maintain communication stability.

[0031] Scenarios and steps Scenario 1: Hard mesh networking As shown in the network topology diagram, 9 people A-I use 9 devices to complete a networking activity. First, 9 people need to use the Mesh networking function on this device to complete teaming up; At least one person (such as B) confirms the completion of teaming up on the mobile phone APP. At this time, the entire routing table list is confirmed; Let's assume that two people (B and H) in the team both open the mobile phone APP, and both can see the list status of 9 people at this time, and all are hard Mesh interconnected; Because at this time everyone can communicate with each other through Mesh networking, even if two mobile phone APPs are online, there is no need to transmit voice information through the mobile phone APP.

[0032] Scenario 2: Hard mesh lost connection and soft mesh increased If the I node is left alone due to the expansion of the activity range, the I node will disappear from the hard mesh routing table of the 8 devices including AH, and the hard mesh routing table of I will become empty; Before I opens the mobile app, the background reports based on the routing tables of B and H that I is offline; I opened the mobile phone APP and tried soft Mesh amplification. Since I was in the group when B confirmed the team formation was completed, after logging into the APP, the background would set B (or H) to R1 and I to R2; The backend will create a multi-person real-time voice chat room, invite B and I into the room, and connect them through the APP; B will transmit everyone's voice to the mobile APP, including B's own voice, as B's voice input, so I can hear everyone else's voice; B will also transmit the sound from the mobile phone, including B's own voice, to the Mesh chip and broadcast it, so the other 7 nodes (A, CH) can hear I's voice.

[0033] Scenario 3: Hard Mesh Split into Two Groups At this time, the scope of activities continued to expand. The original 8 personal pages were divided into two groups connected to each other (AE in one group and FGH in another group), and I was still in one group; At this time, AE's hard mesh team information loses FGH, and FGH's hard mesh routing table loses AE; Since BH are online, the backend can calculate that the eight people are divided into two groups, rather than some people being offline, so the backend will use H as the R of the new group, that is, R3; The calculated routing table at this time will be the same as shown in the figure above; The backend notifies the calculated routing table to the three BHI R nodes through the APP, and the three nodes then synchronize the information to other partners in the same group through Mesh; The backend will pull H's mobile APP node into the real-time voice group. In the group, three nodes BHI communicate with each other. B will transmit the voices of AE and 5 people, and transmit the voices of H and I in the meeting back to the group. Similarly, H will transmit the voices of FGH and 3 people, and receive all the voices of BI in the meeting. At this point, all nodes can still hear the voices of all other nodes and continue to communicate through soft mesh amplification without perception.

[0034] Scenario 4: A node leaves a hard mesh group and joins another At this time, node F moves towards node E, and the hard Mesh distance is out of the range of G. If F opens the mobile app, it will become a separate group like I to join the soft Mesh real-time voice group. However, since F does not open the mobile app, there is no F in the hard Mesh routing table reported by BHI, and F will be disconnected and offline; Node F continues to move towards node E. The distance reaches the hard mesh connection range. Node F can communicate through the hard mesh. However, since the connection has just been made, the connection is still weak. Since F has no other nodes connected, the F routing table will be modified to the AE group, that is, the 6 people in AF become a hard Mesh group, and the three groups still communicate through soft Mesh amplification.

[0035] Scenario 5: Merging two groups of hard meshes At this time, GH also moved towards nodes E and F, and G first contacted F; Due to the hard mesh self-organizing mechanism, GF will become an r-node, and the 8 people from A to H will become an interconnected group; Since GF has just been connected, it is in a weak connection state within 3 seconds. There is no node offline in AH, so the routing table is still AF in one group, GH in another group, and I in a separate group. To avoid poor signal when GF is just connected, AF node blocks GH voice according to whitelist rules. GH voice will continue to be transmitted from soft Mesh. Similarly, GH will also block AF voice and access from soft Mesh. After 3 seconds, the GF connection is considered stable and AH becomes a group. At this time, B (or H)'s APP exits from the voice room, and the soft Mesh becomes two groups of communication again, with R nodes being H and I respectively.

[0036] Compared with the related art, the method provided by the present invention for enhancing the communication stability of self-organizing network team communication equipment by using a mobile phone has the following beneficial effects: The present invention provides a method for enhancing the communication stability of a communication device in a self-organizing network team by using a mobile phone. On the basis of not adding other devices, a low coupling and low power consumption solution is adopted to achieve the purpose of enhancing the communication stability, which is advanced in the industry.
