Detailed implementation manners

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. The components of the embodiments of the present invention described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0041] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0042] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0043] In the description of the present invention, it should be noted that if terms such as "upper", "lower", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the accompanying drawings or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0044] In addition, if terms such as "first", "second", etc. are used only for distinguishing descriptions, they cannot be understood as indicating or implying relative importance.

[0045] It should be noted that the features in the embodiments of the present invention can be combined with each other without conflict.

[0046] With the development of network technology, the star structure, ring structure, bus structure, tree structure, etc. of traditional local area networks all play roles in various fields, providing stable network connections and a large amount of data traffic for billions of people globally. However, the inherent defects in these network structures are gradually emerging. For example, in the star structure, once a single point of failure occurs in the central node, it will cause the entire network to collapse. Another example is that in the bus structure, a large number of buses need to be deployed to connect all communication nodes, resulting in high deployment costs and great implementation difficulties.

[0047] In response to the problems existing in the above network structures, the Mesh network, i.e., the mesh network, has emerged. The Mesh network is currently mainly applied in wireless networks, such as Bluetooth Mesh, Wifi Mesh, Zigbee Mesh, etc.

[0048] However, while the Mesh network overcomes the defects existing in other network structures, it also has some problems of its own. For example, the network construction is complex and the network changes flexibly and dynamically, resulting in greater difficulties in fault troubleshooting and network optimization. How to quickly troubleshoot the faults of the wireless Mesh network, improve stability, and perform reliability optimization has become the most urgent problem for technical personnel to solve.

[0049] In response to the above problems, the existing technology usually uses wireless packet capture tools to analyze the network situation of the wireless Mesh network. Due to the complex construction of the wireless Mesh network and the flexible and dynamic changes in the network structure, the current mainstream troubleshooting method is usually to perform packet capture analysis by combining a hardware packet capture device and a computer. This method can analyze the message content of each node interaction in the network in detail and can also view the communication situation between each node, such as signal strength, routing relationship, consumption duration, and other information.

[0050] The following takes the zigbee Mesh network as an example to illustrate the analysis of the wireless Mesh network by the wireless packet capture tool. Please refer to Figure 1 , Figure 1 which is an example diagram of the wireless zigbee Mesh network provided by the embodiment of the present invention. Figure 1 The zigbee Mesh network in includes 4 nodes, namely node 0x378A, node 0xC691, node 0x9FBD, and node 0x0000. When node 0x378A needs to send a message to node 0x0000, the wireless packet capture tool is used to capture the forwarded messages in the wireless Mesh network.

[0051] Please refer to Figure 2 , Figure 2 which is an example screenshot of the captured forwarded messages provided by the embodiment of the present invention. Figure 2The timestamp in it is usually represented by Timestamp, the stack is usually represented by Stack, the packet information is usually represented by Packet Information, the destination node group is usually represented by PAN Dst., the source MAC is usually represented by MAC Dst., the destination MAC is usually represented by MAC Dst., the MAC sequence is usually represented by MAC Seq., the source NWK is usually represented by NWK Src., and the destination NWK is usually represented by NWK Dst. Among them, NWK is the network layer of ZigBee. Starting from Figure 2 From the message in

[0052] Figure 2 it can be seen that the network layer address of node 0x378A wants to send a command to node 0x0000. First, node 0x378A sends the message to node 0xC691, which then sends it to node 0x9FBD, and then node 0x9FBD sends it to node 0x0000. For each message, the time consumption, routing relationship, signal strength, etc. for transmitting the message can be obtained through a packet capture tool.

[0053]

[0054] From the example of the transmission situation of the second message, it can be seen that the communication duration TimeDelta during the transmission of the second message is 0.00876s, and the link quality Link Quality is -55dBm.

[0055] The above method of analyzing the network situation through a packet capture tool focuses too much on details when analyzing messages, ignores the overall form of the network structure, cannot analyze the overall network structure of the network from multiple dimensions, is difficult to quickly and parallelly analyze the routing relationships and communication qualities of different nodes in the entire network, and cannot directly view the changes in node attributes and the dynamic changes in coupling parameters. Once data reporting is abnormal, it is very difficult to analyze through a single captured message.

[0056] In view of this, the embodiments of the present invention realize the analysis of the wireless network from another perspective, that is, first visualize the wireless network, and perform fault troubleshooting and network optimization based on the visualized wireless network, thereby greatly reducing the difficulty of fault troubleshooting and network optimization. The following will describe it in detail.

[0057] Please refer to Figure 3 , Figure 3 which shows a schematic diagram of an application scenario applicable to the embodiments of the present invention. Figure 3In this case, the wireless network includes a border router 40 and device nodes 30, which communicate with each other in a wireless communication manner. The wireless communication manner can be, but is not limited to, Bluetooth, Wifi, Zigbee, etc. The border router 40 communicates with the server 10 via a network, and the server 10 communicates with the display terminal 20 via a network. This network communication manner can be wireless communication or wired communication, and can be a direct connection or an indirect connection.

[0058] The server 10 can be a physical computer or a virtual machine capable of realizing the same functions as the server 10. It can be an independent physical server or a server cluster or distributed system composed of multiple physical servers, etc. The server 10 can generate a topology structure and send the topology structure to the display terminal 20 for visual display. The server 10 can also provide a web address to the display terminal 20, and the display terminal 20 displays the visual result by accessing this web address. The user can also directly view the visual result using the web browser of the server 10.

[0059] The display terminal 20 is a device with a display function, specifically, it can be a smart control panel, a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart watch, etc., but is not limited thereto.

[0060] The border router 40, also known as an edge router, is a device that routes data packets between one or more local area networks and the backbone network. In the wireless network of the embodiment of the present invention, the border router 40 mainly acts as a gateway and maintains the address allocation of the entire wireless Mesh network, etc.

[0061] The device node 30 includes a forwarding node capable of communicating with the border router. For example Figure 3 In the device node 30 directly communicating and connecting with the border router 40, the forwarding node is a node with a forwarding function, which is used to realize the data packet forwarding function between nodes in the wireless network. In the wireless network of the embodiment of the present invention, the forwarding node also mainly acts as a relay. The forwarding node stores neighbor table and routing table information, and the neighbor table records the device nodes with physical links to the forwarding node. In the field of smart home, the forwarding node can be a smart socket, a smart wall socket, etc.

[0062] The device node 30 can also include terminal nodes, which refer to some devices with low power consumption and no forwarding function. In the field of smart home, the terminal nodes can be temperature and humidity sensors, human body sensors, motion and stillness sensors, etc.

[0063] The device node 30 may also include one or more of a terminal node and a forwarding node. Of course, a forwarding node may also have a physical link with multiple other forwarding nodes at the same time, or have a physical link with multiple terminal nodes at the same time, etc. The routing table records the node information that the forwarding node needs to forward to. After ensuring that the data packet reaches the forwarding node through the previous hop, according to the forwarding path description in the routing table, a suitable next-hop forwarding path is selected for forwarding.

[0064] Taking the home application scenario as an example, please refer to Figure 4 , Figure 4 which shows a schematic diagram of a home scenario applicable to the embodiments of the present invention. Figure 4 In it, the wireless network includes a home boundary router 401, a smart wall socket 301, a temperature and humidity sensor 303, and a total volatile organic compound (TVOC) sensor 304. Figure 4 The dotted lines in

[0065] represent wireless connections. For example, the TVOC sensor 304 is wirelessly connected to the smart wall socket 301. Figure 4 It can be understood that although the server 10 and the display terminal 20 are not explicitly shown in

[0066] In fact, the home boundary router 401 can communicate with the server 10, so as to send the neighbor table to the server 10 through the home boundary router 401, enabling the server 10 to generate the topology structure of the wireless network according to the neighbor table, perform visualization processing on the wireless network, and the display terminal 20 can communicate with the server 10 to visually display the topology structure and communication status information sent by the server 10. Figure 3 and Figure 4 In the application scenarios of Figure 3 and Figure 4 , the embodiments of the present invention further provide a hardware structure block diagram of a computer device 50. The computer device 50 may be Figure 3 and Figure 4 the server 10 in Figure 5 , Figure 5 which shows the hardware structure block diagram of the computer device 50 provided by the embodiments of the present invention. The computer device 50 includes a processor 51, a memory 52, a bus 53, and a communication interface 54. The processor 51 and the memory 52 are connected through the bus 53, and the processor 51 communicates with external devices through the communication interface 54.

[0067] The processor 51 may be an integrated circuit chip with the ability to process signals. In the implementation process, each step of the above method can be completed by the integrated logic circuit in the hardware of the processor 51 or the instructions in the form of software. The above-mentioned processor 51 may be a general-purpose processor, including a central processing unit (CPU for short), a network processor (NP for short), etc.; it may also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components.

[0068] The memory 52 is used to store programs, such as the first network visualization processing device 100 or the second network visualization processing device 200 in the embodiments of the present invention. Both the first network visualization processing device 100 and the second network visualization processing device 200 include at least one software function module that can be stored in the memory 52 in the form of software or firmware. After receiving the execution instruction, the processor 51 executes the program to implement the network visualization processing method in the embodiments of the present invention.

[0069] The memory 52 may include a high-speed random access memory (RAM: Random Access Memory), and may also include a non-volatile memory. Optionally, the memory 52 may be a storage device built into the processor 51, or a storage device independent of the processor 51.

[0070] The bus 53 may be an ISA bus, a PCI bus or an EISA bus, etc. Figure 5 It is represented by only one bidirectional arrow, but it does not mean that there is only one bus or one type of bus.

[0071] Those of ordinary skill in the art can understand that Figure 5 The structure shown is only for illustration, and it does not limit the structure of the above computer device 50. For example, the computer device 50 may also include more or fewer components than those shown Figure 5 in the figure, or have a different configuration from that shown Figure 5 in the figure.

[0072] Based on the above Figure 3 and Figure 4 application scenarios, the embodiments of the present invention also provide a network visualization processing method applied to the server 10 in Figure 3 and Figure 4 Please refer to Figure 6 , Figure 6The figure shows a network visualization processing method applied to a server provided by an embodiment of the present invention. The method includes the following steps:

[0073] Step S100: Receive the neighbor tables sent by each forwarding node through the border router. The neighbor table includes the adjacent communication links between the device nodes and the corresponding forwarding nodes and the signal strength of each communication link.

[0074] In this embodiment, as a specific implementation, the device node may include one or more terminal nodes, may also include one or more forwarding nodes, or may include terminal nodes and other forwarding nodes at the same time.

[0075] In this embodiment, the neighbor table of the forwarding node is used to store the link information between the forwarding node and each adjacent device node. The link information includes the communication links between the forwarding node and each adjacent device node and the signal strength of each communication link. As a specific implementation, the forwarding node may actively send a probe request frame or a frame listening preset frame to each device node in the wireless network to collect information about its neighbors. Once a response frame to the probe request frame from other device nodes is received, or after parsing the preset frame received from other device nodes, if it meets the neighbor matching relationship, a neighbor relationship can be established with the device node, and the link information with this neighbor can be updated to the neighbor table.

[0076] In this embodiment, each forwarding node may send its respective neighbor table to the border router in real time or periodically. The border router 40 aggregates the neighbor tables of each forwarding node and sends them to the server 10.

[0077] In this embodiment, due to the different relative positions of the forwarding node and the device node 30, or the different communication performances of the forwarding node and the device node 30 itself, the signal strength between the forwarding node and the device node 30 is also different. For example, when there is a wall and when there is no wall between the forwarding node and the device node 30, the corresponding signal strengths are different. When the antenna quality of the device node 30 is different, the signal strength between it and the forwarding node is also different. Taking the forwarding node as an intelligent wall switch as an example, Table 1 is an example of the neighbor table of the intelligent wall switch.

[0078] Table 1

[0079]

[0080]

[0081] Step S110, generate the topology of the wireless network according to the neighbor table; the topology includes the communication status information between device nodes in the wireless network, and the communication status information includes the communication links between device nodes and the signal strength of each communication link.

[0082] In this embodiment, the topology is an abstract representation method that does not consider physical attributes such as the size and shape of objects, but only uses points or lines to describe the actual positions and relationships of multiple objects. The topology does not care about the details of things, nor about the proportional relationship between them, but only represents the mutual relationship between multiple objects within a certain range in the form of a graph. As a specific implementation, the points (also called vertices) in the topology can be used to represent the device nodes 30 (including forwarding nodes and terminal nodes), the edge between two vertices in the topology represents the communication link between the device nodes 30 represented by these two vertices, and the weight of the edge between two vertices in the topology represents the signal strength of the communication link between the device nodes 30.

[0083] Step S120, send the topology to the display terminal, so that the display terminal visually displays the topology and the communication status information.

[0084] In this embodiment, the server 10 sends the topology to the display terminal 20, and the display terminal 20 visually displays the topology and the communication status information.

[0085] In this embodiment, please refer to Figure 7 , Figure 7 shows an example diagram of the visualization of a wireless network provided by an embodiment of the present invention. Figure 7 In the topology, the temperature and humidity sensor, TVOC sensor, smart wall socket, and edge router are all represented by vertices in the topology. Taking the TVOC sensor and the smart wall socket as an example, the edge between the two represents the existence of a communication link between the two, and the number shown on the edge is the signal strength during signal transmission, that is, the signal strength from the TVOC sensor to the smart wall socket is 121. As a specific implementation, the quality of the signal can be further defined according to the magnitude of the signal strength. For example, a signal strength greater than 100 is set as excellent, and a signal strength greater than 80 and less than 100 is set as good.

[0086] The above method provided by the embodiment of the present invention realizes the visualization of the wireless network by visually displaying the topology, and improves the efficiency of fault troubleshooting and network optimization based on the visualized wireless network.

[0087] It should be noted that in this embodiment, the forwarding node(s) can be one or more. When there are multiple forwarding nodes, the multiple forwarding nodes are all communicatively connected to the border router. At this time, each forwarding node corresponds to a neighbor sub-table. The neighbor table obtained by the border router after summarizing the multiple neighbor sub-tables sent by the multiple forwarding nodes. As a specific implementation, the forwarding node can periodically send its own neighbor sub-table to the border router, and the border router summarizes it to obtain the neighbor table.

[0088] In this embodiment, due to the flexible change characteristic of the wireless network structure, in order to facilitate users to perform fault troubleshooting and network optimization according to the dynamic changes of the wireless network, the embodiment of the present invention also provides a correspondence between the topology structure and the corresponding time point, so that users can query the topology structure at a specified time point. Please refer to Figure 8 , Figure 8 shows another network visualization processing method applied to a server provided by the embodiment of the present invention. The method includes the following steps:

[0089] Step S130, obtain the reception time of the received neighbor table, and establish a correspondence between the reception time and the topology structure.

[0090] In this embodiment, the topology structure corresponding to the reception time is generated based on the neighbor table received at this reception time. As a specific representation, an identifier can be set for each topology structure, and the correspondence between the identifier and the corresponding reception time is stored. For example, the correspondence is shown in Table 2:

[0091] Table 2

[0092] Topological identifier Receiving time 1 2021-9-9 09:30

[0093] It means that the topology structure with the identifier 1 is generated based on the neighbor table received at 09:30 on September 9, 2021, and the topology structure represents the communication status information at 09:30 on September 9, 2021.

[0094] Step S140, according to the correspondence, determine the communication status information of each device node in the topology structure at the reception time.

[0095] In this embodiment, after establishing the correspondence between the reception time and the topology, the correspondence can also be stored so that the user can query the topology at a specified time point or within a specified time range, and then more accurately and comprehensively trace or track the dynamic changes of the topology of the wireless network. For example, the neighbor tables and routers generated by each forwarding node are collected in real time or at a preset period, and then a topology representing the communication status between device nodes in the wireless network is generated based on the neighbor tables and routing tables collected at this time. By comparing the topologies at different times, it is possible to know the changes in the topology of the wireless network during a certain period, and then know the changes in the communication status between device nodes in the wireless network, so as to troubleshoot faults for device nodes whose communication status changes from connected to disconnected, or optimize the performance of device nodes whose communication status changes from good to poor.

[0096] In this embodiment, in order to more vividly display the selected forwarding paths between node devices and more intuitively display the forwarding paths to facilitate maintenance personnel to quickly locate problems, the embodiment of the present invention also provides another method for visualizing the forwarding paths. Please refer to Figure 9 , Figure 9 FIG. shows another network visualization processing method applied to a server provided by the embodiment of the present invention. The method includes the following steps:

[0097] Step S150: Receive the routing table sent by the border router. The routing table is sent by the forwarding node to the border router. The routing table includes the previous hop node corresponding to the forwarding node and the next hop node corresponding to the previous hop node. The previous hop node is the device node that sends the data to be forwarded to the forwarding node, and the next hop node is used to represent the device node to which the forwarding node needs to send the data to be forwarded.

[0098] In this embodiment, in addition to the neighbor table, the forwarding node also includes a routing table. In addition to sending the neighbor table to the border router 40, the forwarding node can also send the routing table to the border router 40. The routing table includes the previous hop node corresponding to the forwarding node and the next hop node corresponding to the previous hop node. The previous hop node of the forwarding node is one of the device nodes that sends the data to be sent to the forwarding node among the device nodes, and the next hop node of the forwarding node is one of the device nodes to which the forwarding node sends the data to be sent. That is, the data to be forwarded is sent from the previous hop node to the forwarding node, and the forwarding node forwards the data to be forwarded to the next hop node corresponding to the previous hop node. Taking the forwarding node as an intelligent wall switch as an example, Table 3 is an example of the routing table of the intelligent wall switch.

[0099] Table 3

[0100] Previous hop node Next hop node TVOC sensor Border router

[0101] It should be noted that different routing algorithms are adopted by the wireless network, and the selection of the forwarding path is also different. Correspondingly, the information in the previous hop node and the next hop node in the routing table is also different. Taking the wireless Mesh network as an example, there are many factors affecting the routing path of the wireless Mesh network, such as the communication signal strength of the link, the number of routing levels of communication, the power consumption of communication, etc. The routing algorithms that can be adopted in the embodiments of the present invention include, but are not limited to, the AODV (Ad hoc On-Demand Distance Vector, AODV) routing algorithm. For example, it can be used to visualize the topology structure of the wireless network for the flooding routing relationship.

[0102] Step S160: Determine the forwarding path corresponding to forwarding the data to be forwarded from the previous hop node to the next hop node according to the routing table.

[0103] In this embodiment, by visually displaying the forwarding path, it is possible to intuitively understand all reachable paths from a certain node to other nodes, and how many routing intermediate nodes are required for each reachable path.

[0104] Step S170: Generate the topology structure corresponding to the wireless network according to the neighbor table and the forwarding path; the topology structure also includes the forwarding paths between the device nodes in the wireless network.

[0105] For a clearer display of the visualization of the forwarding path, please refer to Figure 10 , Figure 10 which shows an example diagram of the visualization of the forwarding path provided by the embodiments of the present invention. Figure 10 In it, the TVOC reports the data through the node intelligent wall switch with forwarding function to the border router, and the forwarding path of the data is as shown by the solid line with an arrow in Figure 10 : TVOC -> intelligent wall switch -> border router.

[0106] In this embodiment, as a specific implementation manner, in order to more vividly display the forwarding path, the forwarding path can also be presented in the form of an animation or highlighting. It is also possible that when the mouse hovers over any forwarding node or terminal node, the forwarding node or terminal node is highlighted, and the forwarding path of the data in the forwarding node or terminal node is animated or highlighted, so as to facilitate the maintenance personnel to quickly locate the problem.

[0107] It should be noted that in this embodiment, the forwarding node(s) can be one or more. When there are multiple forwarding nodes, the multiple forwarding nodes are all communicatively connected to the border router. At this time, each forwarding node corresponds to a routing sub-table, and the border router uses the routing table obtained by summarizing the multiple routing sub-tables sent by the multiple forwarding nodes. As a specific implementation, the forwarding node can periodically send its own routing sub-table to the border router, and the border router summarizes it to obtain the routing table.

[0108] In this embodiment, as a specific application method, technicians can also intuitively view the multi-path selection relationship of data communication according to the visual display of the topological structure before and after the change of the wireless network. If the data to be forwarded cannot be forwarded as expected, it can be analyzed from the signal strength in the figure. For example, it is caused by poor communication quality of a certain link and needs to optimize this link. At this time, technicians can have sufficient and real basis to adjust the position of the device, or adjust the signal reception sensitivity of the device, or the communication link between each device node for network optimization. The following provides an example of analyzing the wireless network communication situation according to the visual display of the topological structure before and after the change of the wireless network.

[0109] Take Figure 7 as the visual example diagram before the change of the wireless network. From Figure 7 it can be seen the connection relationship of all devices and the communication reachable paths and connection signal quality between devices. For example, the signal from the TVOC sensor 304 to the smart wall socket 301 is 121, which belongs to an excellent signal, and the signal strengths from the smart wall socket 301 to the smart wall socket 301 are 127 and 123, which also belong to excellent signals.

[0110] In Figure 7 add two smart wall switches 302 and one TVOC sensor 304. Please refer to Figure 11 Figure 11 which shows the visual example diagram after the change of the wireless network provided by the embodiment of the present invention. From Figure 11 it can be seen that for the changed wireless network, the signal strength from the TVOC sensor 304 to the smart wall socket 301 changes from the original 121 (excellent) to 102 (excellent). At the same time, a new connection relationship is added from the smart wall socket 301 to the smart wall switch 302, and the packets reported by the newly added TVOC sensor 304 reach the home border router 401 through the smart wall switch 302.

[0111] There are Figure 7 and Figure 11From the comparison, it can be analyzed that when the message reported by the newly added TVOC sensor reaches the smart wall switch 302, the smart wall switch 302 compares multiple paths that can be forwarded to the home border router 401. After evaluation, it is found that the signal from the smart wall switch 302 to the smart wall socket 301 is only 85 (good), and the signal strength reaching another smart wall switch 302 is 77 (medium). Therefore, finally, the link with a signal strength of 142 (excellent) directly reported to the home border router 401 is selected.

[0112] Through such analysis, technicians can intuitively view the selection relationship of multiple paths for data communication, as well as the fundamental reasons why a certain path is not selected. In addition, once the message reported by the TVOC sensor cannot directly reach the home border router 401 and the message is lost midway, it can also be analyzed from the signal strength in the figure that it is due to poor communication quality of a certain link and needs to be optimized.

[0113] In this embodiment, in addition to visualizing the information in the neighbor table and / or routing table, the embodiment of the present invention also provides another method for visualizing the connection information between the forwarding node and the device node. Please refer to Figure 12 , Figure 12 shows another network visualization processing method provided by the embodiment of the present invention for a server. The method includes the following steps:

[0114] Step S180, receiving the connection information sent by the border router. The connection information is sent by the forwarding node to the border router and is used to characterize the connection situation between the forwarding node and the device node.

[0115] In this embodiment, the connection information includes, but is not limited to, signal strength, communication link latency, number of retransmissions, communication quality, etc. As a specific implementation, the forwarding node can periodically obtain the above connection information according to the forwarding situation of the forwarded data.

[0116] Step S190, taking the connection situation as the weight of the corresponding edge in the topological structure. Among them, the forwarding node and the device node are represented by vertices in the topological structure, the physical link between the forwarding node and the device node is represented by the edge between the vertices in the topological structure, and the connection information between the forwarding node and the device node is represented by the weight of the edge between the vertices in the topological structure.

[0117] In this embodiment, as a specific implementation, different colors can be used to visually display different connection information.

[0118] In this embodiment, the dynamic changes of the wireless network can be selectively displayed as needed. For example, by visualizing the wireless network at a specified time point or within a specified time period through a neighbor table, the dynamic changes of the neighbor relationships among the nodes in the wireless network can be intuitively understood. By visualizing the wireless network at a specified time point or within a specified time period through a routing table, the dynamic changes of the communication path selection among the nodes in the wireless network can be intuitively understood. By visualizing the wireless network at a specified time point or within a specified time period through connection information, the dynamic changes of the connection status among the nodes can be intuitively understood. Thus, the coupling parameters and selection parameters related to various change factors can be analyzed more comprehensively, and the network optimization efficiency is improved from another dimension.

[0119] Based on the same inventive concept, an embodiment of the present invention further provides a network visualization processing method applied to Figure 3 and Figure 4 the display terminal 20 shown therein, which will be described in detail below.

[0120] Please refer to Figure 13 , Figure 13 which shows a network visualization processing method applied to a display terminal provided by an embodiment of the present invention. The method includes the following steps:

[0121] Step S200, display a network visualization interface; the network visualization interface is used to visually display the wireless network, and the wireless network includes multiple device nodes, and the device nodes include forwarding nodes capable of communicating with the border router.

[0122] Step S210, in the network visualization interface, display the topological structure among the device nodes generated based on the neighbor tables forwarded by each forwarding node through the border router; the neighbor table includes the adjacent communication links existing between the device nodes and the corresponding forwarding nodes and the signal strength corresponding to each communication link; the topological structure includes the communication status information among the device nodes in the wireless network.

[0123] To more intuitively represent the physical links between the device nodes and the signal strength of the physical links, as a specific implementation manner, the topological structure includes vertices, the edges between the vertices, and the weights of the edges between the vertices. The vertices in the topological structure represent the device nodes; the edge between two vertices in the topological structure represents the physical link between the device nodes represented by the two vertices; the weight of the edge between two vertices in the topological structure represents the signal strength of the physical link between the device nodes represented by the two vertices.

[0124] The above method provided by the embodiments of the present invention can efficiently troubleshoot faults and optimize the network by visually displaying the communication links and signal strengths of the communication links between the device nodes and forwarding nodes in the wireless network and the adjacent device nodes.

[0125] In this embodiment, in order to more vividly display the selected forwarding path between node devices and more intuitively display the forwarding path to facilitate maintenance personnel to quickly locate problems, the embodiments of the present invention also provide another method for visually displaying the forwarding path applied to the display terminal 20. Please refer to Figure 14 , Figure 14 shows another network visualization processing method provided by the embodiments of the present invention, and this method further includes the following steps:

[0126] Step S220, obtain the routing table in the wireless network; the routing table is forwarded by the forwarding node to the border router, and the routing table includes the previous hop node corresponding to the forwarding node and the next hop node corresponding to the previous hop node. The previous hop node represents the device node that sends the data to be forwarded to the forwarding node, and the next hop node represents the device node that the forwarding node needs to deliver the data to be forwarded to.

[0127] Step S230, determine the forwarding path corresponding to the data to be forwarded from the previous hop node to the next hop node according to the routing table.

[0128] Step S240, in the network visualization interface, display the topological structure corresponding to the wireless network generated based on the neighbor table and forwarding path forwarded by each forwarding node through the border router.

[0129] It should be noted that, in order to more intuitively display the communication status of the device nodes, as a specific implementation manner, the user can trigger the click operation of each device node displayed in the communication interface of the display terminal, and the communication status of the clicked device node can be displayed. As another specific implementation manner, if the clicked device node is a forwarding node, the neighbor table and routing table of the device node can be displayed.

[0130] Based on the same inventive concept, in order to more clearly display the topological structure of the network in the actual application environment deployment, the embodiments of the present invention also provide a visualization method for a home network based on a space layout diagram. Please refer to Figure 15 , Figure 15 shows another network visualization processing method provided by the embodiments of the present invention, and this method includes the following steps:

[0131] Step S250: Obtain a spatial layout diagram. The spatial layout diagram includes the location information of each home device node, and the location information is used to determine the link relationship between each home device node. Each home device node and the link relationship form a home network.

[0132] In this embodiment, the spatial layout diagram can be a floor plan. The link relationship between each home device node can be the communication connection relationship or the physical link relationship between each home device node. The home network is composed of each home device node with a link relationship.

[0133] Step S260: In the network visualization interface, display the topological structure between each home device node generated based on the neighbor table forwarded by each first home device through the second home device.

[0134] In this embodiment, the first home device Figure 4 the server 10 in, and the second home device can be Figure 4 the border router in.

[0135] In this embodiment, generating the topological structure of the home network and overlaying the topological structure on the spatial layout diagram deployed in the actual environment for display can more intuitively view the communication process of each home device based on the real environment, and more accurate sources of interference signals, such as the impact of walls on the wireless Mesh network, can be understood according to the real environment. Therefore, maintenance personnel can adjust the network situation reasonably and achieve the purpose of efficiently optimizing the network.
