Description

Technical Field

[0001] This application relates to the field of Internet of Things (IoT) technology, and in particular to a dynamic networking method, apparatus, electronic device, and storage medium. Background Technology

[0002] With the development of wireless communication technology, communication between devices (such as IoT devices like robots) and the outside world (such as other devices) can often be based on dynamic networking technology for data exchange. In related technologies, dynamic networking typically involves grouping various devices that need to communicate with the outside world into network nodes. A central node is selected from all these network nodes and can communicate with all other network nodes. This central node then communicates with the outside world, thereby achieving the goal of communication between all devices and the outside world.

[0003] However, the dynamic networking technology used in the relevant technologies has limitations. For example, each network node communicates with the outside world through a central node. Once the central node goes offline, other network nodes cannot exchange data, resulting in poor network stability.

[0004] It is evident that dynamic networking technology in related technologies has limitations, making it difficult for devices to efficiently network and exchange data. Summary of the Invention

[0005] This application provides a dynamic networking method, apparatus, electronic device, and storage medium, which solves the problem of inefficient dynamic networking between devices. This solution enables each node to perform dynamic networking more flexibly, avoids the impact of some nodes going offline, effectively ensures network stability, and helps devices to efficiently network and complete data exchange.

[0006] Firstly, this application provides a dynamic networking method applied to electronic devices within a wireless local area network (WLAN). The WLAN includes multiple electronic devices, with each electronic device serving as a node within the WLAN. Each electronic device includes a 433 wireless communication module and a wireless network card. The 433 wireless communication module is used for transmitting and receiving data, and the wireless network card has access point (AP) functionality and a wireless connection request function. The dynamic networking method includes:

[0007] The 433 wireless communication module cyclically broadcasts network formation request information, which includes the node ID and connection information of this node.

[0008] If this node has not established a network connection with other nodes, it filters out the target nodes to be connected to this node from the latest received network request information;

[0009] If this node has already established a network connection with other nodes, determine whether it is necessary to replace the connected node;

[0010] If it is determined that the connected node needs to be replaced, the target node to be connected to this node is selected from the latest received network request information.

[0011] Once the target node to be connected is determined, a network connection is established with the target node through the wireless network card based on the connection information of the target node.

[0012] Secondly, this application also provides a dynamic networking device for use in electronic devices within a wireless local area network (WLAN). The WLAN includes multiple electronic devices, with each electronic device acting as a node within the WLAN. Each electronic device includes a 433 wireless communication module and a wireless network card. The 433 wireless communication module is used for transmitting and receiving data, and the wireless network card has access point (AP) functionality and a wireless connection request function. The dynamic networking device includes:

[0021] Fourthly, this application also provides a storage medium storing computer-executable instructions, which, when executed by a processor, are used to perform the dynamic networking method described above.

[0022] In this application's scheme, each node continuously broadcasts its own network request information and receives network request information broadcast by other nodes.

[0028] The embodiments of this application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of this application and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, the accompanying drawings only show the parts related to the embodiments of this application, not all structures. Those skilled in the art, after reading this specification, should be able to conceive that any combination of technical features can constitute an optional implementation method, provided that the technical features do not contradict each other.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more.

In the description of this application, "multiple" means two or more, and "several" means one or more.

[0030] The dynamic networking method provided in this application can be applied to electronic devices used to build wireless local area networks, such as intelligent terminals like mobile robots. It is conceivable that the built wireless local area network includes multiple electronic devices, and the electronic devices are wirelessly connected to each other to achieve data exchange.

[0031] Each electronic device includes a 433MHz wireless communication module and a wireless network card. The 433MHz wireless communication module includes a radio frequency transmitter and a receiver for data transmission and reception, and it uses a 433MHz wireless signal for data transmission and reception. The wireless network card has both AP (Access Point) and wireless connection request functions. In other words, a wireless network card with AP functionality enables the device to perform relay and bridging functions, providing an AP hotspot for other devices to receive and forward data sent by those devices; while a wireless network card with wireless connection request function allows the device to connect to AP hotspots provided by other wireless network cards.

[0032] Figure 1 This is a schematic diagram illustrating the steps of a dynamic networking method provided in an embodiment of this application. It is understood that the dynamic networking method provided in this application can be applied to various electronic devices that need to access a wireless local area network. To more clearly describe the solution of this application, the dynamic networking method is described below from the perspective of an electronic device, and the specific steps are as follows:

[0033] Step S110: Based on the 433 wireless communication module, broadcast the network formation request information in a loop. The network formation request information includes the node ID and connection information of this node.

[0034] Understandably, the device (i.e., this node) cyclically broadcasts its network request information through its own 433 wireless communication module. The time interval between each broadcast can be set according to actual application requirements, allowing the device to continuously broadcast its network request information. Furthermore, since the electronic device is equipped with a 433 wireless communication module, it can also receive network request information broadcast by other devices.

[0035] The network request information includes the node ID (Identity) and connection information for this node. The node ID is an identifier associated with the electronic device itself, such as the device's unique identifier or the unique identifier configured within the local area network when the electronic device connects to the local area network. The connection information is associated with the AP hotspot provided by the wireless network card, such as the AP hotspot name and password, to facilitate other devices connecting to the AP hotspot.

[0036] Step S120: If this node has not established a network connection with other nodes, select the target node to be connected to this node from the latest received network request information.

[0037] For this node, there are two possibilities: it may be in a position where it is establishing a network connection with other nodes, or it may already have established a network connection with other nodes. If this node has not established a network connection with other nodes, it needs to establish a network connection with other nodes to filter out the target node from the latest received network request information. This target node is the node to be connected to this node.

[0038] In one embodiment, the current node filters out the target node by comparing the node IDs of all nodes. Figure 2 This is a schematic diagram illustrating the steps for filtering target nodes according to an embodiment of this application. The specific steps are as follows:

[0039] Step S210: Compare the node ID of this node with the node IDs of other nodes to determine the optional nodes whose node ID values ​​are less than those of this node among the other nodes.

[0040] Step S220: Select the node with the largest node ID value from the available nodes as the target node.

[0041] Understandably, upon receiving a network formation request from another node, this node parses it to determine the node IDs of the other nodes. Then, this node compares its own node ID with the node IDs of the other nodes to identify potential nodes with node IDs lower than its own. The node with the largest node ID among the potential nodes is the target node.

[0042] It's conceivable that the node IDs of each node can be sorted according to their values, allowing nodes with IDs smaller than the current node to be considered as potential candidates. Then, the node with the largest ID among these candidates can be selected as the target node. For example, during the comparison process, the current node can convert each node ID into an integer of equal digits for comparison, using the converted integer as the node ID value to determine the size of each node's ID. Therefore, by comparing node IDs to select the appropriate target node, and with all nodes selecting target nodes according to the same rules, nodes can more flexibly implement dynamic networking to address situations affecting network stability, such as some nodes leaving the network or new nodes joining.

[0043] Step S130: If this node has already established a network connection with other nodes, determine whether it is necessary to replace the connected node.

[0044] If a node has already established a network connection with other nodes, it needs to determine whether it needs to replace the connected node. It is conceivable that in scenarios where a node leaves the network or a new node joins, if the node it is connected to needs to leave the network or a new node needs to connect to it, the node needs to disconnect from the network connection with the currently connected node and then re-establish a network connection with another node.

[0045] Therefore, the situations requiring replacement of the currently connected node include, but are not limited to, situations where a node leaves the network or a new node joins. In some embodiments, the node can listen for network requests broadcast by other nodes. The currently connected node refers to the node currently connected to the node. If the node does not receive a network request from the currently connected node within a preset time period, it can determine that the currently connected node has left the network. Conversely, if the node receives a network request broadcast by a new node, it can determine that a new node needs to join the network. Therefore, the node determines that it needs to replace the connected node.

[0046] Step S140: If it is determined that the connected node needs to be replaced, then select the target node to be connected to this node from the latest received network request information.

[0047] If this node determines that it needs to replace the connected node, it filters the target node from the latest received network request information. For example, it selects the target node to be connected using the filtering method provided in the above embodiment. For example, this node selects the node with the largest node ID value among several nodes whose node ID value is less than its own node ID as the target node by comparing the node IDs of each node.

[0048] It's conceivable that when a currently connected node leaves the network, the network request information received by this node will not include the network request information of the currently connected node. Therefore, this node will not select the currently connected node again during the target node selection process, but will instead select another node as the target node. Similarly, when a new node joins the network, this node can select a target node using the same selection method. Whether a new node is a potential target node for this node depends on its node ID. For example, if the new node's node ID is less than this node's node ID but greater than the node ID of the currently connected node, then the new node is selected as the potential target node.

[0049] In addition, this node needs to disconnect from the network connection with the currently connected node in order to establish a connection with the selected target node. Therefore, it can be understood that this node can either disconnect from the network connection with the currently connected node first and then filter the target node, or filter the target node first and then disconnect from the network connection with the currently connected node.

[0050] Step S150: If the target node to be connected is determined, a network connection is established with the target node through the wireless network card based on the connection information of the target node.

[0051] After identifying the target node to connect to, this node can receive connection information from other nodes, including the AP hotspot name and password of its own wireless network card. Based on the AP hotspot name and password, the node can establish a connection with another node. Therefore, this node establishes a network connection and exchanges data with the target node by connecting to the AP hotspot provided by the target node.

[0052] Therefore, when each node selects the target node and establishes a network connection according to the above filtering rules, each node forms a wireless local area network through the network connection in turn. When a node needs to interact with another node, if there are several other nodes between the two nodes, the data is transmitted sequentially through the intermediate nodes, thereby realizing the data interaction.

[0053] As can be seen from the above scheme, each node continuously broadcasts its own networking request information and receives networking request information broadcast by other nodes, thereby enabling each node to connect to the corresponding nodes to establish a networking connection. Furthermore, when a node has already established a networking connection with other nodes, it can determine whether to replace the connected node based on the received networking request information. This allows each node to flexibly and dynamically form a network to cope with situations such as some nodes leaving the network or adding new nodes, effectively ensuring network stability and helping devices to efficiently form a network and complete data exchange.

[0054] In some embodiments, if this node determines that it does not need to replace the connected node and the connected node is a disabled node that has stopped requesting wireless connections, it is conceivable that the electronic device, as a disabled node, disables its wireless connection request function, and the device cannot connect to the AP hotspot provided by other wireless network cards. In this case, this node maintains its connection with the currently connected node, and this node also needs to filter out alternative nodes from other nodes, and these alternative nodes serve as another target node to be connected to, so that this node can establish a network connection with them.

[0055] For example, in one embodiment, the node obtains the node ID of each node from the latest received network request information, and then selects the node with a node ID value less than that of the node as a candidate node. The node can select another node from the candidate nodes other than the currently connected node, such as selecting the node with a node ID value only less than that of the currently connected node as a candidate node, that is, the node ID of the candidate node is less than the node ID of the currently connected node and greater than the node ID of other nodes in the candidate nodes.

[0056] Understandably, since the current connection node stops requesting wireless connections, when data transmission is needed, the current connection node cannot transmit data to the next node. Instead, the current node can transmit data to the next node through another node (i.e., a backup node) to achieve data interaction between nodes.

[0057] Figure 3 This is a schematic diagram illustrating the establishment of a network connection between nodes according to an embodiment of this application, wherein... Figure 3 'a' represents a diagram illustrating the network connection established by nodes after a node leaves the network. The node ID values ​​of nodes A, B, C, and D decrease sequentially. If node C leaves the network, the original network connection between node B and node C, as well as the original network connection between node C and node D, are both broken. Node B then uses node D, whose node ID value is less than that of node C, as its target node, thus establishing a network connection between node B and node D.

[0058] and Figure 3 'b' represents a diagram illustrating the network connection established by existing nodes when a new node joins the network. Similarly, the node IDs of nodes A, B, C, and D decrease sequentially. Node E, as a newly joined node, has a node ID less than node C's but greater than node D's. Although both nodes E and D are potential candidates for node C, node E's node ID is greater than C's. Therefore, for node C, its target node for connection changes to node E. Node C disconnects its existing network connection with node D and establishes a network connection with node E, while node E retains its network connection with node D.

[0059] Figure 3 c represents a diagram illustrating the establishment of network connections among nodes when a node is disabled. Similarly, the node ID values ​​corresponding to nodes A, B, C, and D decrease sequentially. Node C is a disabled node, meaning that there is no longer a network connection between node C and node D. Node B selects node D as another target node to establish a network connection with node D. Of course, the original network connection between node B and node C is still maintained.
