[0044] In order to facilitate understanding of the technical solutions of the present disclosure, some technical terms involved in the present disclosure are introduced below.

[0045] MESH technology, wireless mesh network technology, is a technology that connects multiple wireless network devices in a mesh topology, and realizes a wireless network with wider coverage and more stable signals through wireless signal transmission and relay between devices. Each node (i.e. wireless device) has the functions of routing and forwarding, can establish communication links with other nodes, and transmit data packets to the destination through these links. This distributed network structure can effectively solve the problems of weak signals and insufficient coverage in traditional wireless networks, and provide better coverage and signal quality.

[0046] In order to make the technical solution of the present disclosure clearer and easier to understand, the power transmission line monitoring device provided by the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0047] As described in the background technology section, by real-time monitoring of transmission lines, the reliability of power supply can be ensured, potential faults such as wire breakage or insulator damage can be discovered and prevented in a timely manner, thereby reducing unexpected power outages and ensuring the continuity and stability of the power grid. Effective monitoring helps to optimize the operation and maintenance of the power grid, arrange maintenance reasonably, reduce operating costs, and extend the life of equipment. At the same time, it warns of the risks brought by natural disasters (such as ice disasters, typhoons) and man-made damage, provides a rapid response mechanism, and minimizes damage. In addition, monitoring data provides important support for the construction of smart grids, promotes the digital transformation of power equipment, and improves management efficiency and service quality. Good monitoring measures can also help power companies fulfill their environmental protection and social responsibilities, avoid environmental problems caused by power facility failures, such as forest fires, and also ensure compliance with relevant laws and regulations to protect public safety. Therefore, ensuring the safe and stable operation of the power grid can effectively guarantee the normal electricity demand of social production and residents' lives, and improve the reliability and economy of power supply.

[0048] In the northwestern Shagohuang area, since there is no public network coverage in the northwestern Shagohuang area, traditional transmission line monitoring requires manual operation and relies on ground personnel to walk or drive. For example, a 50-kilometer 220kV line inspection requires at least 3 people and takes at least 9 days, which is inefficient and costly. In addition, it is difficult to determine whether the staff are in place, the manual recording method is costly and inefficient, and standardized operations are difficult to implement.

[0049] In view of this, the embodiment of the present application provides a transmission line monitoring device and method. It includes: a data acquisition module, a main control module, a communication module and an edge computing module; the data acquisition module is connected to the storage module and the main control module, and is used to collect environmental information of the transmission line, and send the environmental information to the control module; the main control module is connected to the data acquisition module, the communication module, the edge computing module and the positioning module, and is used to obtain and collect environmental information of the transmission line, and monitor the transmission line according to the environmental information; the communication module is connected to the main control module, and provides a communication basis for the data acquisition module, the main control module, the communication module and the edge computing module based on the MESH technology; the edge computing module is connected to the data acquisition module and the main control module, and is used to receive the environmental information collected by the data acquisition module, calculate the environmental information, and send the calculation result to the main control module. By using MESH technology as the basis for data transmission in the communication module, fast data transmission is achieved, and self-organizing and self-recovery mechanisms are performed based on MESH network nodes, so that the device can automatically adjust the data transmission path, improve the reliability and applicability of the device, ensure continuous data transmission, and quickly locate the fault point, formulate emergency repair plans more quickly, and achieve faster response to reduce losses.

[0050] like Figure 1 As shown, the transmission line monitoring device method includes: a data acquisition module, a main control module, a communication module and an edge computing module;

[0051] The data acquisition module is connected to the storage module and the main control module, and is used to collect environmental information of the power transmission line and send the environmental information to the control module;

[0052] The main control module is connected to the data acquisition module, the communication module, the edge computing module and the positioning module, and is used to acquire environmental information of the power transmission line and monitor the power transmission line according to the environmental information;

[0053] The communication module is connected to the main control module, and provides a communication basis for the data acquisition module, the main control module, the communication module and the edge computing module based on MESH technology;

[0054] The edge computing module is connected to the data acquisition module and the main control module, and is used to receive the environmental information collected by the data acquisition module, calculate the environmental information, and send the calculation result to the main control module.

[0055] In some embodiments, Figure 2As shown, the transmission line monitoring device is placed on the pole tower through a fixed bayonet, wherein the south side of the transmission line monitoring device can be connected to monitoring equipment such as cameras and various sensors, and the north side is connected to each pole tower equipment through MESH for self-organizing network. The platform side equipment serves as a public network access point and is connected to the monitoring platform to form a transmission line monitoring system.

[0056] In some embodiments, Figure 3 As shown, the data acquisition module includes: a camera, an inclination sensor, a meteorological sensor, and a pressure sensor, etc. The camera, the inclination sensor, the meteorological sensor, and the pressure sensor are used to obtain environmental image information, the inclination angle of the pole tower connected to the transmission line, and the pressure information of the current environment of the transmission line, and the environmental image information, the inclination angle of the pole tower connected to the transmission line, and the pressure information of the current environment of the transmission line are sent to the main control module as the basis for the main control module to control other modules, thereby realizing comprehensive and accurate collection of various environmental parameters related to the transmission line, and the basis for making precise control instructions. The data acquisition module integrates a camera, an inclination sensor, a meteorological sensor, and a pressure sensor. The data acquisition module can not only capture visual information, but also monitor changes in the physical environment, providing a solid foundation for subsequent data analysis, fault warning, and operation and maintenance decisions.

[0057] Specifically, as part of the data acquisition module, the camera is mainly used to collect environmental image information of the transmission line, including static pictures and dynamic videos, and send the static pictures and dynamic videos to the edge computing module. Therefore, according to the static pictures and dynamic videos, it is determined whether there is foreign intrusion within the preset range of the transmission line (for example, there are substances attached to the line that affect the transmission quality of the line), whether the vegetation growth affects the safety of the line, etc. High-definition cameras can provide clear pictures, and cameras with night vision functions can continue to work in low-light or no-light conditions, ensuring all-weather monitoring without blind spots.

[0058] In some embodiments, the camera is equipped with an intelligent analysis algorithm to automatically identify abnormal situations and issue alarms, thereby improving the response speed and accuracy of the system.

[0059] In some embodiments, the inclination sensor is specifically used to measure the inclination angle of the tower connected to the transmission line. In a complex terrain environment, the transmission tower may be offset due to geological changes, strong winds, etc., which may pose a potential threat to the safety of power transmission. By monitoring the inclination of the tower in real time, structural changes can be discovered in time, its stability can be evaluated, and necessary maintenance measures can be taken to avoid large-scale power outages caused by the collapse of the tower.

[0060] In some embodiments, meteorological sensors are used to collect information on climate conditions such as temperature, humidity, and wind speed. These data are very important for understanding the state of the environment in which the transmission line is located, especially in extreme weather conditions such as storms, ice and snow disasters. Meteorological data of the same period can help predict possible damage to power facilities and make preventive preparations in advance. At the same time, long-term accumulated meteorological data can also help study the impact of climate change on the power grid and optimize the planning and operation of the power system.

[0061] In some embodiments, the role of the pressure sensor is to monitor the pressure information of the current environment of the power transmission line. This may involve changes in the pressure of the surrounding air, or additional loads caused by freezing, snow, etc. By monitoring these pressure changes, the mechanical stress on the power transmission line can be more accurately evaluated, thereby ensuring the safety and reliability of the line.

[0062] Furthermore, in order to achieve effective communication of the above-mentioned various sensors, the data acquisition module provides a variety of interface options, such as RS485, industrial Ethernet port and WIFI, etc., to meet the connection requirements of different devices. At the same time, the power transmission line monitoring device in this application supports multiple data protocols internally, including but not limited to the Modbus protocol, which is a communication protocol widely used in the field of industrial automation; GB28181 / RTSP / RTMP video transmission protocol, which is a standard for video stream transmission, ensures efficient and stable transmission of video data. This multi-protocol support enables the data acquisition module to be compatible with more hardware devices, and also simplifies the integration and maintenance of the system.

[0063] In some optional implementations, the communication module is based on MESH technology, and provides a communication basis for the main control module through a combination of MESH technology, 5G communication and WiFi communication. Specifically, a 5G module based on the Spreadtrum platform is used to support all 5G Sub6 bands of China's three major operators and global mainstream bands, and is backward compatible with LTE / WCDMA. It also supports the n1 band of China Unicom and China Telecom, and the 700MHz n28 band of radio and television, and supports multi-slicing function. This device adopts a dual-antenna design, with a 5G speed measurement of 357Mbps downlink and 125Mbps uplink, which meets the data transmission bandwidth requirements of the transmission line.

[0064] In some embodiments, MESH is important as a bearer network connecting adjacent nodes. Figure 4The process shown realizes a centerless self-organizing network. This device is applied to the monitoring scenario of power transmission lines in remote areas. In this scenario, the poles and towers are distributed in a straight line, not a mesh structure. In order to ensure the transmission stability of the network and reduce interference between devices, a three-frequency networking + directional antenna mode is adopted. Through flexible configuration of spectrum resources, network channel transmission is realized. Traditional MESH technology works in single-frequency mode, and the problem of co-frequency interference between nodes is prone to occur, and the bandwidth and signal are attenuated by 50% for each additional hop. After 7 hops, the loan rate decays to a level that is difficult to use. The MESH technology of this device is based on the traditional network structure through improvements to the physical layer, data link layer and core algorithms to improve the networking efficiency. The main key technologies include intelligent frequency hopping technology, intelligent forwarding technology and intelligent routing technology.

[0065] In some implementations, for intelligent frequency hopping technology, each Mesh node has multiple wireless RF modules, working in different frequency bands, which solves the problem of interference between single node transmission and reception at the same frequency. Each node automatically selects the best route to send or forward data packets, fully considering the performance of different RF modules / channels on each node, and using the advantages of multiple frequency bands to improve network throughput, multi-hop performance and transmission stability.

[0066] like Figure 5 As shown in the figure, nodes 1, 2, and 3 dynamically select different subsets from all available frequencies as frequency hopping frequency sets according to their respective wireless environments and spectrum monitoring results. Node 1 selects 5.8GHz (S1), node 2 selects 1.4GHz (S2), and node 3 selects 2.4GHz (S3). These subsets can contain the same frequency or different frequencies. Each node makes its selection independently and is not affected by other nodes. During data transmission, nodes 2 and 3 use the S1 frequency set to send data to node 1; nodes 1 and 3 use the S2 frequency set to send data to node 2; and nodes 1 and 2 use the S3 frequency set to send data to node 3. The same applies if more nodes join. Since each node can intelligently and independently adjust its own frequency hopping frequency set, each communication link in the network can use a unique frequency set to optimize the overall network performance. This process is fully automated, and the system will automatically adjust in real time according to the external wireless environment, spectrum monitoring, and interference conditions. No manual intervention is required, and the operation is simple. While performing high-speed frequency hopping operations, the system will perform dynamic and real-time spectrum monitoring of the entire network. This process is based on the existing frequency hopping frequency list, or within the frequency band supported by the hardware device, and performs detailed real-time perception and spectrum monitoring of the entire frequency band in steps of 1MHz.

[0067] Based on real-time spectrum monitoring data, each node can intelligently select the best frequency point independently according to the external electromagnetic environment and interference conditions to form its own frequency hopping frequency set. Such an intelligent, dynamic, and different frequency set frequency hopping networking strategy not only ensures the efficiency of high-speed frequency hopping, but also effectively avoids interference, enhancing the system's anti-interference ability and overall robustness.

[0068] In some implementations, for intelligent forwarding technology, the characteristics of wireless transmission determine that its link packet loss rate cannot be the same as that of a wired network, and in a wireless mesh network, due to the multi-hop characteristics, the cost of packet loss retransmission is magnified to some extent. Intelligent forwarding technology adopts an intelligent link retransmission strategy according to the real-time network status, effectively avoiding retransmission caused by link layer packet loss and reducing the packet loss rate of multi-hop links.

[0069] In some implementations, for intelligent routing technology, intelligent routing technology uses a multi-factor routing optimization algorithm to comprehensively consider factors such as link information, node status, location, and moving speed to predict link status, effectively improving the self-recovery speed when a link fails, and achieving a more seamless Mesh network connection. A flexible routing management framework is also added to the routing protocol layer, and different routing algorithms and strategies are loaded through simple deployment according to different application scenarios and business needs.

[0070] In some implementations, the wireless WIFI selects a low-power, dual-band module that supports IEEE 802.11a / b / g / n / ac / ax and other standards to meet the needs of on-site inspectors to access the Internet via application software on their mobile phones and process work orders normally.

[0071] In some implementations, for the selection of antennas, the present application selects Figure 6 The directional antenna shown has a large gain, which improves the transmission efficiency and quality; suppresses the backward signal and reduces the interference to other cells; increases confidentiality and transmits in a specific direction, reducing the risk of being intercepted; improves the effective use of radiation power, so that the signal can be transmitted more concentratedly to where it is needed, reducing energy waste; enhances signal strength and anti-interference ability, and improves the stability and reliability of communications.

[0072] In some implementations, the main control module is responsible for coordinating and controlling the operation of the entire system to ensure efficient and stable interaction between the various functional modules. The main control module achieves real-time acquisition and analysis of transmission line environmental information through connections with the data acquisition module, communication module, edge computing module, and positioning module, and monitors and manages the transmission line based on this information. This not only improves the intelligence level of the system, but also provides a strong guarantee for the safety and reliability of power transmission.

[0073] In some embodiments, the main control module uses a processor with an 8-core A53 architecture and a main frequency of 1.6GHz to implement data processing and algorithm operation. At the same time, the processor supports the embedded Linux operating system to run various customized software applications to meet specific monitoring needs. For example, functions such as automated task scheduling, data analysis, and fault diagnosis can be achieved by writing special scripts or programs. In addition, the open source nature of the Linux system also allows developers to flexibly adjust and optimize system performance according to actual conditions.

[0074] In some optional implementations, in order to better connect various sensors and network devices, the main control module integrates rich on-chip resources. These include 2 RS485 interfaces, which can be easily connected to field devices such as inclination sensors and meteorological sensors to achieve direct data collection. As a widely used serial communication standard, RS485 has good anti-interference ability and long-distance transmission performance, and is suitable for use in industrial environments. At the same time, the main control module is also equipped with 2 Gigabit Ethernet ports for connecting network cameras and other network devices. The high-speed transmission rate of the Gigabit Ethernet port ensures the smooth transmission of large amounts of data such as video streams, which is particularly important for application scenarios that require high-resolution images or real-time video monitoring.

[0075] In addition to hardware configuration, the main control module is also responsible for dispatching and controlling various functional modules. In actual operation, the main control module dynamically adjusts the working status of each module according to preset rules and strategies to ensure the optimal operation of the system as a whole. For example, when it is detected that the wind force in a certain area exceeds the set threshold, the main control module can automatically notify the edge computing module to start the corresponding algorithm to evaluate potential risks; if a tower is found to be tilted, the communication module can be immediately called to send an alarm message to the operation and maintenance center so that timely measures can be taken.

[0076] In collaboration with the data acquisition module, the main control module is used to realize the functions of data aggregation and preliminary processing. The main control module receives the original environmental information from the data acquisition module, such as temperature, humidity, wind speed, tilt angle, etc. After preliminary filtering and sorting, it passes the valuable data to the edge computing module for in-depth analysis. This layered processing method not only reduces the burden on the main control module, but also improves the efficiency and accuracy of data processing. In addition, the main control module can also build a model based on historical data to predict future environmental change trends and make early warnings and response measures.

[0077] In some embodiments, for the communication module, the main control module is responsible for sending the locally collected data to the remote server or cloud platform through the appropriate communication protocol, and also receives instructions and updates from the upper system. This allows the transmission line monitoring system to not only work independently, but also integrate into the larger power network management system to achieve information sharing and collaborative operations. The cooperation with the positioning module allows the main control module to accurately grasp the specific location of each monitoring point, which is very critical for operations such as quickly locating fault points and planning inspection routes.

[0078] In some optional embodiments, the edge computing module includes a data analysis module, an image reasoning and recognition module and an early warning module, through which the data analysis module, the image reasoning and recognition module and the early warning module perform data analysis and danger warning prompts on the environmental image information; wherein, the data analysis module and the image reasoning and recognition module pass.

[0079] Specifically, the edge computing module uses domestic TPU processors to realize the processing and analysis of massive image recognition data, judge alarm reminders based on the preset thresholds of the early warning strategy, and store the data locally or send it to the background cloud. Through intelligent analysis, it can automatically and quickly identify the initial hidden dangers of on-site targets.

[0080] In some embodiments, the power transmission line monitoring device further includes a positioning module; the positioning module is used to locate the fault of the power transmission line; wherein the positioning module performs positioning through Beidou technology.

[0081] Specifically, the use of single Beidou positioning can meet the positioning needs in complex environments, realize real-time positioning of the transmission line tower, and provide time to the device to synchronize the time of devices within the network. When an emergency is detected, the fault point can be located quickly, improving the timeliness of problem handling.

[0082] In some embodiments, the power transmission line monitoring device further includes a storage module; the storage module is connected to the data acquisition module and the main control module, and is used to store the environmental information collected by the data acquisition module and the control information of the main control module. The storage module can cyclically store local monitoring data, videos, images, etc.

[0083] In some embodiments, the power transmission line monitoring device further includes: a power supply module; the power supply module is connected to the main control module and is used to provide power to the main control module; wherein the power supply module includes a wind power generation module and a solar power generation module.

[0084] Specifically, the remote areas have sufficient wind and sunshine, so the power supply adopts the wind and solar complementary solution. The wind turbine has a rated power of 300W, a rated voltage of 12V, a starting wind speed of 2.0m / s, a rated wind speed of 13m / s, and a safe wind speed of 55m / s; the solar panel has a rated power of 300W, a conversion rate of ≥22%, and four single crystal A-level pieces are combined; the battery adopts a gel battery with a capacity of 200Ah, ensuring continuous power supply for about 2-3 days in rainy weather.

[0085] In some embodiments, the power transmission line monitoring device is configured to: Figure 7 The process shown is to monitor the transmission line, that is, after starting data collection, the video and interval photography functions are started, the static picture information and dynamic video information are determined, and the static picture information and dynamic video information are transmitted to the edge computing module for detection. Among them, the edge computing module performs detection through a pre-trained AI model. The AI ​​model can be any of a supervised learning model, a deep learning model, a reinforcement learning model, a graph neural network, or a federated learning model, which is not limited here.
