Description

Technical Field

[0001] This application relates to the field of information technology, and particularly to a networking method and system based on Mesh ad-hoc networking technology. Background Art

[0002] In today's information age, large and medium-sized enterprises' dependence on information technology is increasing day by day, and their requirements for security, reliability, and usability have reached a new height. To ensure the stable and efficient flow of internal data information in enterprises, these enterprises have carefully considered their technology selections and spared no expense in resource investment. They have gathered a large amount of manpower to form top-notch technical teams, spent huge material costs, and made every effort to build a dedicated communication system that meets their own business needs. In this way, it not only highlights the enterprises' high attention to information security, but also shows their firm belief and long-term strategy in the digital transformation journey. With dedicated communication methods, enterprises can effectively resist external attacks, ensure the stability and efficiency of data transmission, and lay a solid foundation for their sustainable development and market competition.

[0003] At present, ad-hoc networking technologies are showing a diversified development trend, and various technologies have their own advantages:

[0004] AP (Access Point) ad-hoc networking: An autonomous networking form with a wireless access point as the core. As the center of the wireless network, the wireless access point can connect multiple wireless client devices to build a local area network;

[0005] ZigBee ad-hoc networking technology: Complying with the IEEE802.15.4 standard, it is a low-power, low-rate, short-distance wireless communication means. Named after the bee colony communication mode, it can operate in frequency bands such as 2.4GHz, 868MHz, and 915MHz;

[0006] Wi-Fi Direct ad-hoc networking technology: Launched by the Wi-Fi Alliance, it allows Wi-Fi devices to get rid of the shackles of traditional access points and achieve direct communication, enabling two or more Wi-Fi devices to establish connections and transmit data just like in a conventional AP network. Its working frequency bands are 2.4GHz and 5GHz;

[0007] LoRa ad-hoc networking technology: A low-power long-range wireless communication solution based on spread spectrum technology. By using long code modulation and demodulation to extend the signal transmission distance and reduce power consumption, it has various networking methods, including star-shaped and mesh network structures, etc.;

[0008] Currently, there are a wide variety of ad-hoc networking technologies on the market. Different enterprises select the most suitable technology solutions according to their own characteristics and development needs to meet the requirements in dimensions such as network communication, data transmission, security, and flexibility. However, in the power industry, especially in the field of new energy power generation, the application of existing ad-hoc networking technologies has exposed many shortcomings.

[0009] In the new energy power generation scenario, generator equipment is mostly located in desolate areas such as Gobi deserts and mountaintops. Due to the limitations of communication signal tower construction, the power generation areas often lack 4G and 5G communication signal coverage. At present, the inside of the wind turbines and the photovoltaic areas mainly rely on optical fibers and network cables for communication, while personnel communication depends on satellite phones. At the same time, for information security considerations, strict restrictions are imposed on WiFi signals in the production areas. Such a situation has led to a single communication mode, fixed frequency bands, and complicated line expansion and maintenance work, which has greatly hindered the normal production and operation of enterprises.

[0010] Furthermore, with the accelerating process of the intelligentization of the power industry, a series of large intelligent devices relying on network communication have emerged one after another. Most of these devices use communication methods such as 4G, 5G, and WiFi. However, due to unstable network signals, a large number of communication lines need to be laid in the early stage. And to ensure information security, the setting of specific communication frequency bands reduces the reusability of the devices. In view of this, the new Mesh wireless self-organizing network communication technology has emerged, aiming to solve the current communication dilemma.

[0011] By deeply analyzing the existing self-organizing network communication modes, it is not difficult to find that the following defects exist in the wireless self-organizing network:

[0012] AP (Access Point) self-organizing network: The expansion and maintenance of the network rely on a professional operation and maintenance team, and the expansion operation depends on the support of wired devices. The processes of line laying, routing configuration, and fault tolerance mechanism setting are cumbersome. Once a sudden failure occurs at the AP transmitter access point, the entire regional network will be paralyzed.

[0013] ZigBee self-organizing network technology: The communication rate is relatively low, making it difficult to carry a large number of real-time data transmission tasks; the transmission distance is limited, usually in the range of 10 - 100 meters. Expanding the coverage range will cause a sharp increase in costs and power consumption; there are protocol differences or functional shortcomings in the products of different manufacturers, resulting in poor interoperability; the self-organizing network efficiency is limited, the network construction takes a long time, the stability is poor, and the management difficulty is large.

[0014] Wi-Fi Direct technology self-organizing network technology: The power consumption is relatively high, more power-consuming than Bluetooth technology, and it is easy to pose a threat to the battery life of the device; there are security vulnerabilities. Attackers can intercept the WLAN direct connection address by borrowing the mobile phone WiFi MAC broadcast message, and then implant malicious code and seize the execution permission to achieve the monitoring and control of the device.

[0015] LoRa self-organizing network technology: The data transmission rate is slow, and it is only applicable to low-speed data stream or scattered data transmission scenarios; based on the half-duplex working mode, a large amount of data back-and-forth is extremely likely to cause delays; the security of early protocol versions is weak, and when developers build their own protocols, security and encryption are often difficult to guarantee; in the case of scarce spectrum resources, multiple devices are prone to competing for the same frequency band, causing interference and resulting in performance degradation.

[0016] Mesh self-organizing network technology, also known as Wireless Mesh Network (WMN), builds a new network architecture with its self-organizing, self-configuring, and self-healing characteristics. Summary of the Invention

[0059] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0060] In the first aspect, as Figure 1 shown, the embodiment of this application provides a networking method based on Mesh ad hoc networking technology, including the following steps:

[0061] Step S1: Plan the networking area and perform node positioning;

[0062] Step S2: Designate the Mesh wireless communication frequency band and channels within the networking area;

[0063] Step S3: Install node devices at each positioned node, preset the designated communication frequency band and channels for each node device, and configure the routing protocol to form a network architecture.

[0064] This application constructs a brand-new network architecture through networking node positioning, designation of frequency bands and channels, and routing configuration. The mode and frequency band are flexible, and the line expansion and maintenance work are simple, effectively ensuring the normal production and operation of enterprises.

[0065] In one embodiment, the said Step S1: Plan the networking area and perform node positioning specifically includes the following steps:

[0066] Step S11: Obtain the planned networking area; specifically, clarify the application scenarios and requirements of the networking. The application scenarios include home scenarios, office scenarios, and industrial scenarios; the networking requirements are further divided according to each application scenario. In the home scenario, the networking area usually covers each room in the home, including the living room, bedroom, study, kitchen, and bathroom, etc., and it is necessary to ensure that each room can have good network coverage to meet the daily Internet access, video viewing, smart home device connection, etc. needs of family members; the office scenario involves each space in the office area, such as office cubicles, meeting rooms, negotiation rooms, rest areas, etc. Different areas have different network requirements. Office cubicles may be mainly used for daily office software use and file transfer, while meeting rooms may need to support multiple people to conduct high-definition video conferences and data sharing simultaneously, with higher requirements for network bandwidth and stability; in the industrial scenario, the networking area may be factory workshops, warehouses, logistics channels, etc. In the factory workshop, the network needs to cover the locations of production equipment to ensure data transmission and remote monitoring between equipment; the warehouse needs to ensure the network connection of equipment such as goods inventory and logistics management;

[0067] Step S12: Obtain the spatial layout and signal shielding condition of the networking area; specifically, conduct a detailed survey of the communication area, comprehensively consider the regional spatial layout and signal shielding condition, and accurately plan the distribution positions of the nodes. First, determine the location of the main node, ensuring that this place has convenient optical fiber access conditions and meets the installation requirements of devices such as switches and routers, laying a solid foundation for subsequent networking operations; use a signal strength tester to detect the signals at various positions in the area at different time periods. Focus on detecting the signal conditions around objects with significant signal shielding effects, such as metal structures (such as metal frames, elevator shafts), concrete walls (especially load-bearing walls), and glass curtain walls. Record the areas with severe signal attenuation, and draw a signal shielding distribution map to visually display the scope and degree of the shielding area;

[0068] Step S13: Plan the distribution positions of the nodes of the Mesh self-organizing network according to the spatial layout and signal shielding condition of the networking area.

[0069] In one embodiment, the step S2: Define the Mesh wireless communication frequency band and channels in the networking area, specifically including the following steps:

[0070] Step S21: Count the frequency band and channel information in the networking area, and obtain the statistical results of the frequency band and channel; specifically, use professional network analysis tools or use the management interface of network equipment to count the frequency band and channel information in the networking area, and obtain the statistical results of the frequency band and channel; more specifically, use a spectrum analyzer to scan and analyze the signals within a certain frequency range. Place the antenna of the spectrum analyzer in the networking area, set the parameters such as the scanning frequency range, and it can detect various frequency band signals in the area and display the signal strength, frequency and other information. Through the analysis of this information, the usage of different frequency bands and the channel occupancy in each frequency band can be counted; or, use some equipment specially used for wireless network testing, which can search and display the frequency band and channel information used by the surrounding wireless networks. For example, some wireless testers can scan the 2.4GHz and 5GHz frequency bands, list the specific channels used by all detected wireless signals in the current area, and provide other relevant data such as signal strength and signal-to-noise ratio, so that users can fully understand the wireless channel status in the networking area; or, most wireless routers have a management interface, and by logging into the management interface, you can view the frequency band and channel information used by the current router. In addition, some advanced wireless routers can also scan the surrounding wireless networks and display the frequency bands and channels used by other nearby routers, helping users understand the surrounding network environment so that they can reasonably choose their own frequency bands and channels to avoid interference; or, use the management interface of the wireless access point to provide information about its own configured frequency bands and channels. At the same time, some enterprise-level wireless APs also have spectrum analysis functions, which can scan and count the wireless frequency bands and channels in their coverage area, providing a basis for network administrators to optimize network deployment;

[0071] Step S22: Delineate Mesh wireless communication frequency bands and channels according to the obtained statistical results of frequency bands and channels.

[0072] In one embodiment, the step S22: defining the Mesh wireless communication frequency band and channel according to the obtained statistical results of the frequency band and channel, specifically includes the following steps:

[0073] Step S221: Based on the occupancy of frequency bands and channels and communication requirements, initially select a frequency band and a channel; the commonly used Mesh wireless communication frequency bands currently are 2.4 GHz and 5 GHz. The signal of the 2.4 GHz frequency band has a relatively long propagation distance, but the transmission rate is relatively low, and it is easily interfered. For example, Bluetooth devices, microwave ovens, etc. may generate interference in this frequency band. The 5 GHz frequency band has a high transmission rate and can provide faster data transmission, but the signal propagation distance is relatively short and the wall penetration ability is also weak; referring to the statistical results, if a large number of signals are detected in the 2.4 GHz frequency band, it indicates that this frequency band is relatively crowded and may generate more interference. At this time, choosing the 5 GHz frequency band may obtain better communication quality. On the contrary, if there are too many signals in the 5 GHz frequency band and the 2.4 GHz frequency band is relatively idle, the 2.4 GHz frequency band can be considered; if it is evaluated that the 5 GHz frequency band is more suitable and the statistical results show that the signal strength of channel 48 in the 5 GHz frequency band is low and the interference is small, channel 48 can be used as the initial channel for Mesh wireless communication first;

[0074] Step S222: After selecting the initial frequency band and channel, it is necessary to conduct tests in the actual environment. By testing indicators such as signal strength, transmission rate, and packet loss rate at each node position of the Mesh network, the actual communication effect of the selected frequency band and channel is evaluated. If it is found that the test results are not ideal, such as there are dead spots in signal coverage, unstable transmission rate, etc., the selection of the frequency band and channel needs to be reconsidered;

[0075] During the operation of the Mesh network, it may be affected by changes in the surrounding environment, such as the addition of other wireless devices, changes in building structures, etc., resulting in interference or performance degradation of the originally selected frequency band and channel. Therefore, it is necessary to monitor and adjust the frequency band and channel regularly or dynamically according to the actual situation to ensure that the Mesh network always maintains good communication performance.

[0076] In an embodiment, the step S3: Install node devices at each located node, preset the designated communication frequency band and channel for each node device, and configure the routing protocol to form a network architecture, which specifically includes the following steps:

[0077] Step S31: According to the previous plan, preset the exclusive communication frequency band and channel for each node device in the networking area; specifically, according to the network plan, confirm the type and quantity of the required node devices, ensure that the devices are in good condition and the accessories are complete, such as power adapters, network cables, etc.; for wireless Mesh node devices, it is necessary to check whether the antenna is firmly installed (if it is a detachable antenna) and whether the appearance of the device is damaged;

[0078] Step S32: Install each node device in an orderly manner. By virtue of the custom communication frequency band, automatic networking among the nodes is realized, and a complete and unobstructed communication network is gradually built. Further, it includes the following steps:

[0079] Install the node device: According to the network plan, mark the device installation points at the selected installation locations. For wall mounting, ensure that the wall is flat and firm enough to bear the weight of the device; for ceiling mounting, reserve sufficient space and ensure the safety of the ceiling structure. If power wiring is involved, plan the power line route in advance to ensure stable power supply and avoid interference with other signal lines;

[0080] Configure the frequency band and automatic networking for the node device: Connect a portable computer to the newly installed node device (either wired or wirelessly, depending on the device's initial settings), open a browser, enter the device's default management IP address (usually found in the device manual), and enter the device management login interface. Enter the default username and password (also refer to the device manual) to log in to the device management background; in the device management background, find relevant options such as "Wireless Settings" or "RF Settings", in the frequency band setting area, select the custom frequency band. For devices that support frequency band fine-tuning, according to the previously planned frequency band range, manually enter parameters such as the center frequency and bandwidth. For example, if the custom frequency band is 5250 - 5350 MHz, set the center frequency to 5300 MHz and the bandwidth to 100 MHz, save the frequency band settings. Some devices may need to be restarted for the settings to take effect. In the device management background, find relevant options such as "Mesh Settings" or "Automatic Networking", enable the automatic networking function, and set relevant parameters as needed, such as the Mesh network name (SSID), encryption method, and password (to ensure network security). For some devices that support multi-band Mesh, ensure that the frequency band selection is consistent with the previously set custom frequency band. After saving the settings, the node device will start automatically searching for other nodes with the same Mesh network name and matching frequency bands around it and attempt to establish connections.

[0081] In one embodiment, the step S3: Install node devices at each located node, preset the defined communication frequency band and channel for each node device, and configure the routing protocol. After forming the network architecture, it further includes the following steps:

[0082] Step S4: Conduct network testing on the formed network architecture to obtain a network architecture that passes the test.

[0083] In one embodiment, the step S4: Conduct network testing on the formed network architecture to obtain a network architecture that passes the test, specifically including the following steps:

[0084] Step S41: Test the connectivity between nodes; specifically, use a laptop to wirelessly connect to any node in the Mesh network, open the command prompt (Windows system) or terminal (Linux, macOS system), and use the ping command to test the connectivity between each node. For example, ping the IP address of an adjacent node to check for packet loss or excessive latency. If there are connectivity issues, check for errors in device installation, frequency band settings, network configuration, etc.

[0085] Step S42: Test the signal strength and coverage of the network architecture; specifically, use a professional wireless signal testing tool (such as a Wi-Fi analyzer) to detect the signal strength at different locations within the network coverage area, draw a signal strength coverage map, and evaluate whether the signal coverage is uniform and whether there are signal blind spots. If insufficient signal coverage is found, the position of the node device, the antenna direction, or the number of nodes can be adjusted to optimize the coverage area;

[0086] Step S43: Test the network performance of the network architecture; specifically, use a network performance testing tool (such as Iperf) to perform performance tests such as bandwidth and throughput between different nodes. According to the test results, adjust network parameters such as optimizing frequency band settings and adjusting routing protocol parameters to improve the overall network performance and ensure the integrity and smoothness of the communication network.
