Description

Method, device, terminal equipment and storage medium for networking through network number

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on October 7, 2023, with application number 202311285055.7 and invention name “Method, device, terminal equipment and storage medium for networking through network number”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of wireless battery management systems, and in particular to a method, apparatus, terminal device, and storage medium for networking through a network number. Background Art

[0003] In a wireless battery management system (WBMS), monitoring data transmission for battery cells is typically achieved by establishing a secure and stable local area network within the battery pack. Since wireless communication IC chips produced in the same batch have the same network ID, during initial networking, after the master node begins operation, slave nodes join the master node on a first-come, first-served basis based on the number of accessible slave nodes provided by the master node. Networking is then established based on the master node and the slave nodes that first joined the master node's network. However, with this networking approach, during non-initial networking, since slave nodes join the master node on a first-come, first-served basis, there's no guarantee that the slave nodes joining the master node during non-initial networking are the same as during initial networking. Therefore, after non-initial networking, manual configuration of the slave nodes is required to adjust the slave nodes networking with the master node to ensure that the same slave nodes are connected to the master node during non-initial networking. This networking approach requires manual configuration of slave nodes during non-initial networking, resulting in low networking efficiency and human-induced network accuracy.

[0034] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] As shown in FIG1 , a method for networking using a network number provided in an embodiment of the present application includes:

[0036] Step S1: Control the master node to broadcast the master node's network number to all slave nodes, so that when the slave node determines that its own network number is the same as the master node's network number, it will form a network with the master node;

[0037] Step S2: After the network is established, the MAC address and network ID of the master node are obtained;

[0038] Step S3: Generate a network number to be updated according to the MAC address of the master node and the network number of the master node;

[0039] Step S4: updating the network numbers of the master node and the slave nodes networked with the master node according to the network number to be updated.

[0040] In the wireless battery management system, there are devices that serve as master nodes and devices that serve as slave nodes. For ease of description, the following description uses the term "master node" to refer to devices that serve as master nodes, and the term "slave node" to refer to devices that serve as slave nodes.

[0041] Regarding step S1, in a preferred embodiment, before controlling the master node to broadcast the master node's network number to all slave nodes, the process further includes: obtaining a preset networking topology; determining, based on the networking topology, the number of slave nodes that need to be networked with the master node; selecting a corresponding number of slave nodes from all slave nodes that need to be networked with the master node, and setting the network numbers of the selected slave nodes to be the same as the network number of the master node. Furthermore, the specific number of slave nodes that need to be networked with the master node can be adjusted based on changes to the preset networking topology during actual use.

[0042] Specifically, before the initial networking is performed, a preset networking topology is obtained. Preferably, the preset networking topology is a star topology as shown in FIG2 . In the current FIG2 , the number of slave nodes that need to be connected to the master node can be determined to be 4 through the star topology.

[0043] After determining the number of slave nodes that need to be networked with the master node, a corresponding number of slave nodes that need to be networked with the master node are selected from all the slave nodes of the wireless battery management system, and the network numbers of the selected slave nodes and the master node are set to the same network number. Optionally, the network number setting can be written to the chip of the device where the corresponding node is located by the administrator of the wireless battery management system or the user using the system through custom settings. After the network number is written, the chip of the device corresponding to the master node and the chip of the device corresponding to the slave node are configured through software or other means. Through the above embodiment, the master node and the slave nodes that need to be connected to the master node can be distinguished from the wireless battery management system by pre-writing the same network number before networking.

[0044] After the wireless battery management system is powered on, a communication connection is established between the master node and each slave node in the wireless battery management system. The master node is controlled to broadcast the network number written in the master node to all slave nodes in the wireless battery management system. Upon receiving the network number broadcast by the master node, each slave node matches the network number broadcast by the master node with the network number of its own slave node. If the matching network number is the same, the slave node forms a network with the master node. If the slave node determines that its network number is different from the master node's network number, it will not form a network with the master node.

[0045] Specifically, for each slave node, when receiving the network number broadcast by the master node, the network number broadcast by the master node is matched with the network number of its own slave node. If the matched network number is not the same, the slave node refuses to form a network with the master node.

[0046] After all slave nodes have completed the verification of the network number with the master node, the initial networking is completed. In this networking, network data transmission between the master node and each slave node can be carried out according to the set network topology architecture.

[0047] In step S2, after the initial networking of the master node and the corresponding slave node described in step S1 is completed, the MAC address and network ID of the master node in the networking are obtained. Preferably, the MAC address and network ID of the master node and the MAC address and network ID of the slave node during the initial networking can be stored in the mainboard of the wireless battery management system or other storage device, so that the next time the network is established, the network can be quickly established based on the initial networking information.

[0048] For step S3, in a preferred embodiment, generating the network number to be updated based on the MAC address of the master node and the network number of the master node includes: generating the network number to be updated by summing the MAC address of the master node and the network number of the master node by means of character strings.

[0049] Specifically, the MAC address of the master node obtained in step S2 and the network number are summed up to generate a new network number (ie the network number to be updated).

[0050] In step S4, the network numbers of the master node and slave nodes that have completed networking in step S2 are updated with the newly generated network numbers in step S3 (i.e., the network numbers to be updated). The next time a network is quickly established, the updated network numbers can be used directly for networking without having to rewrite and configure the network numbers of the master node and slave nodes to be networked.

[0051] It should be added that after the networking is completed, a network data communication connection is established between the master node and the slave node. The master node can further obtain more information about the slave node, such as the unique address of the slave node and other related information, providing a network foundation for the subsequent construction of a more secure network.

[0054] The networking module is used to control the master node to broadcast the network number of the master node to all slave nodes, so that when the slave node determines that its own network number is the same as the network number of the master node, it will be networked with the master node;

[0055] The network number update module is used to obtain the MAC address of the master node and the network number of the master node after the networking is completed; generate the network number to be updated based on the MAC address of the master node and the network number of the master node; and update the network number of the master node and each slave node networked with the master node based on the network number to be updated.
