[0017] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0018] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0019] First, to facilitate understanding of the embodiments of the present invention, some terms or nouns involved in the present invention are explained below:

[0020] In the field of power transmission line operation and maintenance, the large side and the small side are two directions defined according to the direction and numbering convention of the line. The two ends of the line will be assigned different numbers. The direction from the end with a smaller number to the end with a larger number is called the large side, and the opposite is the small side.

[0021] Traveling wave data plays an important role in power system fault diagnosis, especially in fault detection and location of transmission lines. Traveling waves, also known as traveling waves or fault traveling waves, refer to voltage or current waves generated by sudden changes in line impedance when a fault occurs on a power line. They propagate along the line at the speed of light. Traveling wave data contains transient information of the fault, such as the time when the fault occurs and the waveform characteristics of the traveling wave, which is an important basis for fault location and type identification.

[0022] Fast Fourier Transform (FFT) is an algorithm used to efficiently calculate the discrete Fourier transform (DFT) and its inverse transform.

[0023] According to an embodiment of the present invention, a spacer rod embodiment is provided. Figure 1 is a schematic diagram of the structure of a spacer bar according to an embodiment of the present invention. Figure 1 As shown, the above-mentioned spacer includes: a gripper 10, a cavity 20, wherein the gripper 10 is provided with a state sensing chip 102, and the cavity 20 is provided with a sensor unit 122 and a main control device 124, wherein:

[0024] The state sensing chip 102 is used to collect the operation data of the power transmission line;

[0025] The sensor unit 122 is used to collect environmental data of the power transmission line;

[0026] The main control device 124 is connected to the state sensing chip 102 and the sensor unit 122, and is used to determine the state monitoring result of the transmission line based on the operation data and the environmental data, wherein the state monitoring result is at least used to indicate whether there is an abnormality in the transmission line.

[0027] Optionally, in the above method, by integrating a state sensing chip in the gripping part of the spacer, the operation data of the transmission line, such as current, electromagnetic field and temperature, can be directly monitored; the sensing unit in the cavity is responsible for collecting environmental data, which can include but is not limited to the temperature and humidity of the micro-topography, atmospheric pressure and the dynamic posture of the conductor. This design can fully grasp the line status and surrounding environment information without additional monitoring equipment, reduce the repeated installation of equipment, and reduce costs and operation and maintenance difficulties. The main control device is connected to the state sensing chip and the sensing unit, and is responsible for processing the collected operation data and environmental data. It can automatically evaluate the health status of the line and identify possible abnormal conditions, thereby realizing intelligent monitoring and early warning. By setting the above spacer, the purpose of data collection and status monitoring of the transmission line can be achieved only through a spacer with a built-in monitoring device, thereby achieving the technical effect of improving the integration of monitoring equipment and the convenience of installation and operation and maintenance, and comprehensively monitoring the transmission line, thereby solving the technical problems of the need to install additional monitoring devices to monitor the status of the transmission line in the related technology, the low integration of monitoring equipment, the insufficient measurement, and the difficulty of installation and operation.

[0028] Optional, Figure 2 is a schematic diagram of the external structure of an optional spacer bar according to an embodiment of the present invention, such as Figure 2 As shown, the gripper of the spacer bar is the part in contact with the transmission line and can be used to fix the position of the transmission line. The spacer bar cavity is used as a supporting part to separate the conductors of each transmission line from each other.

[0029] Optionally, the main control device may be composed of multiple components and / or units. For example, the main control device may include, but is not limited to, a processor, a memory, a safety protection unit, a data processing unit, and a data analysis unit. Among them, the processor is the "brain" of the entire intelligent spacer system, responsible for controlling and coordinating the operation of the system. It receives raw data from state sensing chips (such as current chips, electric field chips, temperature chips) and other sensing units (such as environmental temperature and humidity sensing units, MEMS sensing units, atmospheric pressure sensing units, image acquisition units), executes data acquisition strategies, and performs preliminary processing on the data according to a preset algorithm. The processor is also responsible for scheduling resources to ensure the correct transmission of data between units and the orderly execution of system functions. The memory is used to store a large amount of data generated during the operation of the system, including collected operating data and environmental data, processed intermediate results, and final analysis reports. It can ensure the safe storage of data, and retain key information even when the device is powered off or abnormal, which is convenient for subsequent data analysis and fault diagnosis. The memory may also contain program code and preset parameter configurations for running data analysis algorithms. The security protection unit is responsible for protecting the system from external malicious attacks or internal failures, ensuring the security of data transmission and the stability of equipment operation. It may include security measures such as encryption algorithms, firewalls, and intrusion detection systems to prevent data from being stolen, tampered with, or destroyed. It may also include physical protection mechanisms such as overload protection and temperature control to adapt to the harsh environment that power equipment usually faces. The data processing unit preprocesses the raw data, such as filtering, normalization, and error correction, to improve the quality and availability of the data. It ensures the accuracy of data analysis by eliminating noise and correcting deviations. The data processing unit may also be responsible for data compression, encoding, and other tasks to optimize data storage and transmission efficiency.

[0030] In an optional embodiment, a current transformer energy acquisition unit is also provided on the grip, wherein the current transformer energy acquisition unit is connected to the state sensing chip and is used to power the state sensing chip based on the current induced from the transmission line.

[0031] Optionally, the current transformer (CT) energy acquisition unit directly uses the current in the transmission line for energy conversion to power the state sensing chip. In this way, the state sensing chip no longer relies on an external power supply, thereby reducing dependence on energy supply in line maintenance, reducing energy costs, and improving the self-sufficiency and continuity of operation of the system. Monitoring equipment in related technologies often requires batteries or other external power supplies, which may be insufficient or fail due to harsh environments, poor maintenance, etc. The integration of the current transformer energy acquisition unit can ensure that the state sensing chip has a stable power supply, and can continue to work even under extreme climatic conditions, which can greatly improve the overall reliability of the monitoring system. The use of current transformer energy acquisition can avoid the deployment of batteries or other flammable and explosive power supply equipment near the transmission line, reducing the risk of safety accidents such as fire or explosion caused by power failure. At the same time, there is no need to replace batteries regularly, which can reduce the workload of operation and maintenance and improve the convenience of installation and operation of monitoring equipment. Stable energy supply is a prerequisite for monitoring equipment to accurately collect and process data. The current transformer energy-taking unit provides continuous power support for the state-sensing chip, ensuring that the state-sensing chip can accurately collect the line's operating data at any time, thereby providing a more reliable data basis for fault diagnosis and state assessment. In addition, the current transformer energy-taking unit uses the current on the existing transmission line as energy, which can achieve minimal impact on the environment and maximum energy utilization. This design is in line with the green and environmentally friendly concept of the smart grid and helps save energy and reduce emissions.

[0032] Optionally, in addition to powering the state sensing chip, the current transformer energy extraction unit can also be connected to other devices in the spacer bar that need power to provide power for such devices.

[0033] In an optional embodiment, a wireless networking unit and a communication unit are also provided in the cavity, wherein the wireless networking unit is used for wireless communication between the state sensing chip and the sensor unit and the main control device respectively; the communication unit is used for transmitting the monitoring data collected by the spacer rod to the monitoring server, wherein the monitoring data includes at least one of the following: operation data, environmental data, and state monitoring results.

[0034] Optionally, the introduction of a wireless networking unit enables the spacer bar to exchange data and work in collaboration with other nearby monitoring devices. This short-range wireless communication can not only realize the rapid sharing of data, but also build a local sensor network to improve the data aggregation efficiency and processing capacity. The addition of the communication unit enables the spacer bar to remotely transmit the collected monitoring data, including operation data, environmental data and status monitoring results, to the monitoring server or control center. Through the wireless networking unit, the initial processing and aggregation of data can be achieved between the monitoring devices, reducing the amount of data transmission and reducing the communication cost. After the data is transmitted to the monitoring server, more in-depth analysis and processing can be carried out, such as fault prediction and trend analysis based on big data, thereby improving the intelligence level of the entire system. The combined use of wireless networking units and communication units helps to build a smart grid monitoring network with wide coverage and rapid response. This network can not only monitor the line status in real time, but also quickly locate the problem area when a fault occurs, providing real-time data support for emergency response and maintenance. The characteristics of wireless communication can reduce the dependence on wired networks, making the installation and operation and maintenance of spacers easier. The wireless networking unit enables the equipment to self-organize and optimize the communication path, while the remote communication unit can avoid frequent on-site inspections and data recovery, reducing operation and maintenance costs. By integrating the wireless networking unit and the communication unit, the spacer can not only achieve local and remote data communication, but also work together with other components of the smart grid to jointly build a comprehensive, efficient and intelligent monitoring and early warning system, which is of great significance to improving the safety and operation efficiency of the power grid.

[0035] Optionally, the communication unit may be, but is not limited to, a fourth generation mobile (4G) communication unit or a fifth generation mobile (5G) communication unit. The high-speed data transmission capability of 4G / 5G technology can ensure the timely delivery of real-time monitoring and early warning information, which is essential for remote operation and maintenance and safety management. Even in the event of failure of some local communication nodes, the 4G / 5G communication unit can ensure remote transmission of data and ensure that important information will not be lost, thereby improving the overall robustness and reliability of the system.

[0036] In an optional embodiment, the state sensing chip includes at least: a current chip, an electric field chip, and a temperature chip, wherein the current chip is used to collect conductor current data of the transmission line, wherein the conductor current data includes steady-state current and transient current; the electric field chip is used to collect electric field strength information within a predetermined neighborhood of the transmission line; the temperature chip is used to collect conductor temperature data of the transmission line; wherein the operating data includes conductor current data, electric field strength information, and conductor temperature data.

[0037] Optionally, the current chip can monitor steady-state current and transient current. Through steady-state current monitoring, the current of the transmission line under normal operation can be continuously monitored to provide data support for evaluating the load condition of the line and identifying overload or fault precursors. Through transient current monitoring, the instantaneous current change of the transmission line when a fault occurs can be captured, which is crucial for quickly locating the fault point and identifying the fault type. The traveling wave data contained in the transient current is an important input for the fault location algorithm. The electric field chip can be used for electric field strength information collection and monitoring the strength of the electric field around the transmission line. It can be used to evaluate the electromagnetic compatibility of the line, check the working status of equipment such as insulators, and warn of possible abnormal phenomena such as corona discharge or electrostatic discharge. The temperature chip can be used for transmission line conductor temperature data collection and real-time monitoring of the conductor temperature, which helps prevent line fusing or fire caused by overheating. It is also an important basis for conductor ice monitoring.

[0038] By integrating current chips, electric field chips and temperature chips, it is possible to fully monitor the operating status of transmission lines, including information on current load, electric field environment and conductor temperature, providing a detailed data basis for the stable operation of smart grids. Current chips and temperature chips can capture early signs of faults, such as current anomalies (steady state or transient) and temperature mutations, and issue early warnings in time to avoid major accidents. The electric field information monitored by the electric field chip can reflect environmental changes around the line and help identify external factors that may affect line operation, such as weather conditions and electromagnetic interference from nearby equipment, thereby enhancing the environmental adaptability and operational reliability of the system. The data collected by these chips are combined with environmental data as part of the operating data and analyzed by the main control device, which can more accurately judge the health status of the line and improve the intelligence level and fault response speed of the smart grid.

[0039] In an optional embodiment, the sensing unit includes at least: an ambient temperature and humidity sensing unit, a micro-electromechanical system sensing unit, an atmospheric pressure sensing unit and an image acquisition unit, wherein the ambient temperature and humidity sensing unit is used to collect ambient temperature data and ambient humidity data of the environment in which the transmission line is located; the micro-electromechanical system sensing unit is used to collect motion characteristic data of the transmission line, wherein the motion characteristic data includes at least: posture data, acceleration data and angular velocity data of the transmission line; the atmospheric pressure sensing unit is used to collect atmospheric pressure data of the environment in which the transmission line is located; the image acquisition unit is used to collect image data within a predetermined neighborhood range of the transmission line; wherein the environmental data includes ambient temperature data, ambient humidity data, motion characteristic data, atmospheric pressure data and image data.

[0040] Optionally, the ambient temperature and humidity sensing unit is used to monitor the ambient temperature and humidity of the micro-topography where the transmission line is located, which is crucial for determining icing conditions, preventing equipment aging and corrosion, and evaluating the thermal load of the equipment. A preliminary judgment on whether the icing conditions are met provides a basis for subsequent icing monitoring and thickness calculation. Changes in environmental parameters can affect the physical state of the line and equipment. For example, increased temperature may cause conductor expansion, and increased humidity may cause insulator flashover. Therefore, continuous monitoring of ambient temperature and humidity helps to adjust the operation strategy in a timely manner and prevent accidents.

[0041] Micro-Electro-Mechanical Systems (MEMS) sensing units are used to collect motion characteristic data (i.e., MEMS sensor data) such as the attitude, acceleration, and angular velocity of transmission lines, which are very important for monitoring dynamic behaviors such as the dancing, wind deflection, and vibration of the conductors. Through precise measurements, the stability of the line can be evaluated and potential failures or safety issues can be predicted, such as the dancing of the conductors that may cause a short circuit between the lines. The small size and high sensitivity of MEMS sensors make them ideal for harsh environments, ensuring stable operation in various climatic conditions.

[0042] The atmospheric pressure sensing unit is used to monitor the atmospheric pressure of the environment in which the transmission line is located, which helps to identify changes in meteorological conditions, such as storms, typhoons, etc., which may pose a threat to the safety of the line. Atmospheric pressure data can be combined with other environmental data to predict weather changes, take countermeasures in advance, and reduce weather-related failures.

[0043] The image acquisition unit is used to collect image data within the predetermined neighborhood of the transmission line, realizing panoramic visualization monitoring of the channel corridor, which is an important supplement to the traditional monitoring method. Through image data, abnormal situations such as foreign object intrusion (such as kites, balloons), tree line distance too close, fire, etc. can be identified, enhancing the real-time response capability to environmental threats. Image data combined with computer vision and deep learning technology can realize automated monitoring and early warning, reducing the frequency and cost of manual inspections.

[0044] By integrating the above four sensing units, the spacer can become a comprehensive monitoring device that not only monitors the physical state of the line, but also senses changes in the surrounding environment, providing comprehensive and real-time data support for the smart grid. Real-time collection of environmental data helps to establish more accurate fault warning models, such as ice monitoring models and conductor dancing models, thereby improving the adaptive ability and fault response speed of the smart grid. The integration of these sensors and comprehensive monitoring of data can reduce the need for multiple independent monitoring devices, simplify installation and operation and maintenance, and improve the overall integration and reliability of the system.

[0045] It should be noted that the acceleration data indicates the acceleration change of the conductor in three-dimensional space (X, Y, and Z axes). In transmission lines, due to the influence of wind or other mechanical factors, the conductors will vibrate or dance. Acceleration data can reflect the vibration intensity and frequency characteristics of the conductors under these effects, and is one of the important parameters for evaluating conductor dancing and wind deviation. By monitoring the acceleration data, the instantaneous vibration and long-term dancing behavior of the conductor can be detected, and timely warnings can be given for safety risks that may be caused by dancing. Angular velocity data reflects the speed at which the conductor rotates around its axis. In the case of wind deviation, the conductor may twist, which not only changes the spatial posture of the conductor, but also may affect the strength and electrical properties of the conductor. Angular velocity data can help analyze the degree and frequency of twisting of the conductor, and is a key indicator for evaluating the effect of wind deviation.

[0046] In an optional embodiment, the image acquisition unit includes: a first camera and a second camera, wherein the first camera is used to collect image data in a channel corridor corresponding to the transmission line along a first direction; the second camera is used to collect image data in the channel corridor along a second direction, wherein the first direction is opposite to the second direction.

[0047] Optionally, by setting two cameras facing each other, the spacer can realize all-round and no-dead-angle monitoring of the corridor environment. Whether it is the large side or the small side, environmental changes can be captured in time to ensure the comprehensiveness and continuity of the monitoring range. The first camera and the second camera collect image data in real time, which can quickly discover potential safety hazards, such as trees growing too fast and approaching wires, foreign objects (kites, balloons, etc.) intrusion, fire, ice and other abnormal conditions, to achieve immediate warning, and help operation and maintenance personnel take preventive measures in advance to avoid accidents. The two cameras collect images of the same area from different angles, which can form data redundancy and enhance the stability and reliability of the monitoring system. At the same time, comparing the two channels of image data helps to identify moving objects (such as by observing the changes in the position of the object in the two images) and the dynamic changes of the environment, providing richer information for fault diagnosis. Image data provides an intuitive visual supplement to the data collected by other sensors. For example, combining temperature and humidity sensor data with the ice coverage in the image can more accurately judge the degree of ice coverage and provide a basis for taking corresponding measures. In the monitoring of conductor dancing, image data can intuitively display the shape and amplitude of the dancing, and combined with MEMS sensor data, improve the accuracy of dancing analysis. The dual-camera design supports the operation of the channel corridor panoramic visualization algorithm model, processes image data through computer vision technology, and automatically identifies and analyzes abnormal situations, thereby reducing the need for manual intervention and improving the operation and maintenance efficiency and intelligence level of smart grids.

[0048] Optionally, the first direction is opposite to the second direction. For example, when the transmission line is a horizontal line, the first direction and the second direction may be parallel to the transmission line and in opposite directions.

[0049] Based on the above embodiments and optional embodiments, the present invention proposes an optional implementation mode: Figure 3 is a schematic diagram of an optional internal structure of a spacer rod according to an embodiment of the present invention, such as Figure 3 As shown, the method includes:

[0050] The spacer rod is mainly divided into two parts, namely the gripping part of the spacer rod and the cavity part of the spacer rod. The gripping part of the spacer rod is provided with a state sensing chip, which may include but is not limited to a current chip, an electric field chip, a temperature chip and a CT energy acquisition unit. The cavity of the spacer rod includes a processor, a wireless networking unit, a 4G / 5G communication unit, an environmental temperature and humidity sensing unit, an image acquisition unit (i.e., two-way visualization lens modules (one for the large side of the line and one for the small side of the line)), a data processing unit, a safety protection unit, a data analysis unit, a memory, a MEMS sensing unit, and an atmospheric pressure sensing unit. The gripping part of the spacer rod integrates a multi-parameter sensing chip to monitor the operation data of the transmission line, such as transient current, steady-state current, electromagnetic field, and conductor temperature. Online energy acquisition is achieved through the CT energy acquisition unit; the cavity of the spacer rod is integrated with two visual cameras to realize visual image monitoring of the large and small sides of the channel corridor, and the environmental temperature and humidity sensor unit and the atmospheric pressure sensor unit are integrated to realize the collection of micro-topography environmental temperature and humidity data and air pressure data; the MEMS sensor unit is integrated to realize the dynamic measurement of the spacer rod posture.

[0051] It should be noted that in this application Figures 1 to 3 The specific structure of the spacer bar shown in the figure is only for reference. In specific applications, the spacer bar in this application can be Figures 1 to 3 The spacers shown have more or less structures.

[0052] According to an embodiment of the present invention, a method embodiment for monitoring the operating status of a transmission line is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0053] Figure 4 is a flow chart of a method for monitoring the operating status of a transmission line according to an embodiment of the present invention. Figure 4 As shown, the method comprises the following steps:

[0054] Step S102, obtaining operation data of the power transmission line, wherein the operation data is collected by a state sensing chip installed on a gripper of the spacer bar, the gripper being a component connected to the power transmission line;

[0055] Optionally, by installing a state sensing chip on the gripper, it is possible to monitor the current, electromagnetic field, temperature and other operating parameters of the transmission line in real time, and promptly capture possible transient or steady-state anomalies of the line, such as overload, abnormal temperature rise, electromagnetic field fluctuations, etc. These data are crucial for evaluating the health of the line.

[0056] As an optional embodiment, the execution subject of this embodiment may be a main control device in the above-mentioned spacer rod.

[0057] Step S104, obtaining environmental data of the power transmission line, wherein the environmental data is collected by a sensor unit installed on the cavity of the spacer rod;

[0058] Optionally, the environmental data collected by the sensor unit on the cavity, including ambient temperature and humidity, atmospheric pressure, conductor posture, image information, etc., can reflect changes in the environment around the transmission line, such as meteorological conditions, vegetation growth, foreign object intrusion, etc. These factors may directly affect the safe operation of the line. Monitoring of environmental data helps to detect potential environmental threats early so that preventive measures can be taken.

[0059] Step S106, determining a status monitoring result of the power transmission line based on the operation data and the environmental data, wherein the status monitoring result is at least used to indicate whether there is an abnormality in the power transmission line.

[0060] Optionally, the operation data and environmental data are combined for comprehensive analysis, which can more accurately determine the operation status of the transmission line and identify abnormal patterns. For example, the combination of conductor temperature and ambient temperature data can effectively determine the ice coverage; the conductor posture data and image data of the MEMS sensor unit can be used to analyze the amplitude and frequency of the conductor dancing. Based on the comprehensive information, the data analysis unit can generate line status monitoring results, timely warn of possible faults or safety hazards, and realize intelligent monitoring. The status monitoring results provide real-time and comprehensive line status information for operation and maintenance personnel, which helps them make more accurate decisions, such as dispatching resources for line inspections, repairing or replacing faulty equipment in advance, and adjusting power grid operation strategies. The above methods can significantly improve operation and maintenance efficiency, reduce unnecessary inspection and maintenance costs, and enhance the stability and safety of the power system. Since the state sensing chip and the sensor unit are integrated on the spacer, there is no need to install additional monitoring equipment on the tower and conductor side, which can not only simplify the structure of the transmission line and reduce the complexity of installation and operation and maintenance, but also reduce the load of the equipment and the potential impact on the line. The above method can improve the integration of the monitoring system, reduce the number of monitoring devices, and reduce the complexity and cost of the system by integrating multi-parameter sensing technology, data processing and analysis technology into one device (spacer). At the same time, the intelligent data analysis capability enables the spacer to automatically identify the line status, reduce the dependence on manual intervention, and improve the intelligence level of the system.

[0061] In an optional embodiment, based on the operation data and the environmental data, the status monitoring result of the transmission line is determined, including: based on the conductor current data in the operation data, detecting whether there is a conductor fault in the transmission line to obtain a first detection result; based on the conductor temperature data in the operation data, detecting whether there is a temperature anomaly in the transmission line to obtain a second detection result; based on the motion feature data in the environmental data, determining whether there is a position offset anomaly in the transmission line to obtain a third detection result, wherein the motion feature data at least includes: posture data, acceleration data, and angular velocity data of the transmission line; based on the image data, the ambient temperature data, and the ambient humidity data in the environmental data, determining whether there is an icing anomaly in the transmission line to obtain a fourth detection result; based on the image data, detecting whether there is an abnormal condition within a predetermined neighborhood range of the transmission line to obtain a fifth detection result; and determining the status monitoring result based on the first detection result, the second detection result, the third detection result, the fourth detection result, and the fifth detection result.

[0062] Optionally, the operation status of the transmission line can be comprehensively evaluated from multiple dimensions by analyzing the conductor current, conductor temperature, motion characteristics (position offset), ice coverage, and abnormal conditions of the neighboring environment. This multi-parameter monitoring method can more accurately capture various abnormal phenomena of the line and improve the accuracy and comprehensiveness of fault detection. The fault detection and abnormality identification process is decomposed into multiple independent steps, such as conductor fault detection based on current data, temperature anomaly detection based on temperature data, etc. This hierarchical identification method helps to refine the fault type, which is convenient for operation and maintenance personnel to quickly locate the problem and take targeted measures. The role of environmental data in condition monitoring is particularly pointed out, such as detecting position offset anomalies through motion characteristic data and identifying ice coverage risks through ambient temperature and humidity data. This emphasizes the impact of environmental changes on line safety and helps to establish a more complete fault warning mechanism. The final condition monitoring result is obtained based on the comprehensive analysis of the first to fifth detection results. This data fusion decision-making method can improve the reliability and accuracy of the monitoring results. The comprehensive analysis of multi-sensor data can reduce the possibility of false alarms and missed alarms and improve the intelligence level of fault warning. By real-time monitoring and analysis of operating data and environmental data, abnormal status of the line can be discovered in time, status monitoring results can be generated, and rapid early warning can be achieved. Operation and maintenance personnel can respond quickly based on the early warning information and take preventive measures to avoid or reduce the occurrence of safety accidents. The above methods are helpful to maintain the stable operation of the power grid. By early identification and handling of problems such as conductor faults, temperature anomalies, and ice risks, power outages caused by line faults can be reduced, and the continuity and reliability of power supply can be guaranteed. Through automated data monitoring and analysis, the frequency and complexity of manual inspections can be reduced, thereby improving the operation and maintenance efficiency of smart grids. At the same time, data-based decision support makes operation and maintenance work more refined and scientific, and improves resource utilization efficiency.

[0063] Optionally, the abnormal condition may be, but is not limited to, a wildfire, external damage, or abnormal condition of a foreign object in a conductor.

[0064] Optionally, it is possible but not limited to use a conductor fault diagnosis model to detect whether there is a conductor fault in the transmission line based on the conductor current data in the operation data to obtain a first detection result. Specifically, the conductor fault diagnosis model can be based on the transient current in the conductor current data, identify the transient power frequency and / or traveling wave data in the transient current, combine with the Beidou high-precision timing unit for time calibration, and then calculate the line fault position through a dual-end positioning algorithm, and identify the fault type through a waveform similarity matching algorithm.

[0065] Optionally, it is possible but not limited to use a conductor dancing wind deviation model based on the conductor temperature data in the operating data to determine whether there is a position deviation abnormality in the transmission line to obtain a third detection result. Specifically, the conductor dancing wind deviation model inputs the conductor posture data, acceleration and angular velocity data, and obtains the conductor dancing wind deviation amplitude and frequency after data filtering, integration, detrending, and FFT calculation. The formula of the conductor dancing wind deviation model is as follows:

[0066]

[0067] Where m is the effective mass of the transmission line, c is the damping coefficient, k is the elastic coefficient, y is the displacement of the conductor, F(t) is the external excitation force, and k em is a ratio related to electromagnetic constants.

[0068] Optionally, it is possible but not limited to determine whether there is icing anomaly on the transmission line based on the image data, ambient temperature data and ambient humidity data in the environmental data using a conductor icing monitoring model to obtain a fourth detection result. Specifically, the conductor icing monitoring model uses an environmental meteorological method combined with a visual image monitoring solution. First, it is determined whether the current meteorological environment meets the icing conditions through the ambient temperature and humidity data and the ambient humidity data. For example, if the temperature is greater than 5°C, it is determined that the current environment does not meet the icing conditions. If the temperature is between -10°C and 0°C and the humidity is above 70%, icing is likely to occur. Then, the conductor visualization image data is input and the visualization icing monitoring algorithm is used to analyze the conductor icing and icing thickness values.

[0069] Optionally, it is possible but not limited to use a visual foreign body external damage analysis model based on image data to detect whether there is an abnormal condition within a predetermined neighborhood of the transmission line to obtain a fifth detection result. Specifically, the visual foreign body external damage analysis model inputs visual image data, and after computer vision processing and image algorithm, outputs alarm information such as wildfire, external damage, and foreign matter in the conductor. The steps are to instantiate and segment the image data, divide the image into multiple areas, and then perform refined analysis to identify the warning information in the image through target monitoring.

[0070] Through the above steps S102 to S106, the purpose of collecting data and monitoring the status of the transmission line can be achieved by only using a spacer rod with a built-in monitoring device, thereby achieving the technical effect of improving the integration of the monitoring equipment and the convenience of installation and operation and maintenance, and comprehensively monitoring the transmission line, thereby solving the technical problems in the related technology of needing to install additional monitoring devices to monitor the status of the transmission line, the low integration of the monitoring equipment, the incomplete measurement, and the difficulty of installation and operation and maintenance.

[0071] Based on the above embodiments and optional embodiments, the present invention proposes an optional implementation mode: Figure 5is a flow chart of an optional method for monitoring the operating status of a transmission line according to an embodiment of the present invention, such as Figure 5 As shown, the method can be used for a spacer rod as described in any of the above items, and the method comprises:

[0072] S1, the processor collects multi-parameter sensor data of the gripper part and the cavity part according to the acquisition strategy, including the operation data of the transmission line such as the transient current, steady-state current, electromagnetic field, and conductor temperature data, as well as the environmental data corresponding to the transmission line such as the visualization images of the large and small sides of the corridor, micro-topography temperature and humidity and atmospheric pressure data, and the spacer bar spatial posture data.

[0073] S2 is substituted into the data processing unit to implement data filtering, normalization and other processing, and then substituted into the data analysis unit to evaluate the health status of the transmission line and channel corridor.

[0074] S3, the data analysis unit includes a fault analysis model, an ice visualization analysis model, a wind sway model, and a visualization foreign body damage analysis model, which are used to monitor the status of the transmission line and perform background monitoring and early warning based on the status monitoring results.

[0075] The visual foreign object and external break analysis model inputs visual image data, and after computer vision processing and image algorithm, it outputs alarm information such as wildfire, external breakage, and foreign objects in wires. The steps are to instantiate and segment the image data, divide the image into multiple areas, and then perform detailed analysis to identify the warning information in the image through target monitoring.

[0076] The conductor fault diagnosis model is based on the transient current in the conductor current data, identifies the transient power frequency and / or traveling wave data in the transient current, combines the Beidou high-precision timing unit for time calibration, and then calculates the line fault location through the dual-end positioning algorithm, and identifies the fault type through the waveform similarity matching algorithm.

[0077] The wire waving wind deviation model inputs the wire attitude data, acceleration and angular velocity data, and obtains the wire waving wind deviation amplitude and frequency after data filtering, integration, detrending and FFT calculation. The formula of the wire waving wind deviation model is the same as the above, and will not be repeated here.

[0078] The conductor icing monitoring model adopts the environmental meteorological method combined with the visual image monitoring scheme. First, the ambient temperature data and ambient humidity data are used to preliminarily judge whether the current meteorological environment meets the icing conditions. For example, if the temperature is greater than 5°C, it is judged that the current environment does not meet the icing conditions. If the temperature is between -10°C and 0°C and the humidity is above 70%, icing is prone to occur. Then, the conductor visual image data is input and the visual icing monitoring algorithm is used to analyze the conductor icing and equivalent icing thickness values.

[0079] S4, the background monitoring and early warning module analyzes the characteristic quantities and calculation results output by the mathematical algorithm model, compares them with the preset thresholds, and issues a risk warning prompt when it is greater than the warning range.
