Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric power engineering construction, in particular to an electric power engineering construction safety guarantee monitoring system based on big data. BACKGROUND

[0002] In the tension stringing construction of high-voltage transmission lines, the operation safety evaluation of the traction board and the split conductor system mainly relies on periodic equipment inspection, fixed-point tension monitoring and inference methods based on the experience of operating personnel. These existing means are difficult to comprehensively and real-timely capture the complex dynamic mechanical process and aerodynamic interference effect inside the stringing system. Due to the inability to effectively integrate multi-source dynamic data such as the spatial pose of the traction board, the tension of the traction rope and the sub-conductor, the stringing speed and the like, the inference accuracy of the dynamic fluctuation of the traction force, the stress wave superposition interference and the chain instability risk is insufficient, and there is a lack of in-depth quantitative analysis of the dynamic coupling relationship between the wave impedance potential, the damping attenuation characteristics and the aerodynamic modulation law.

[0003] The monitoring results of the prior art have hysteresis and one-sidedness. The problem lies in the inability to early and accurately locate the instantaneous dangerous point and predict the load evolution trajectory through real-time deep fusion and intelligent analysis of big data. The lack of such analysis capability makes the hierarchical early warning and adaptive control strategy in the construction process often based on incomplete information, which is easy to cause control delay, thereby restricting the improvement of the stringing construction efficiency and increasing the safety risk and operation and maintenance cost of system instability.

[0018] The embodiments of the present application will be described in further detail below in connection with the drawings of the specification.

[0019] In the tension stringing construction process of high-voltage transmission lines, the existing safety evaluation system mainly relies on periodic inspection, fixed-point tension monitoring and manual experience judgment, and it is difficult to master the dynamic mechanical properties of the traction plate and the split conductor system and the influence of aerodynamic interference in real time and comprehensively. Due to the lack of fusion analysis of multi-source dynamic data such as the spatial posture of the traction plate, the tension of the traction rope and each sub-conductor, and the stringing speed, the prediction accuracy of the traction force fluctuation, the stress wave superposition effect and the system instability risk is insufficient.

[0020] Based on this, the present application provides a power engineering construction safety guarantee monitoring system based on big data, which perceives the construction mechanical state by monitoring the traction force in real time, analyzing the oscillation chain reaction and dynamic wind load, predicting the instability trend of the traction plate and the load evolution path, thereby realizing early warning and active intervention of risks. By positioning the instantaneous dangerous point and generating a control strategy, the accident rate is effectively reduced, and the recorded safety log provides data support for subsequent analysis and improvement, thereby comprehensively improving the construction safety and management efficiency.

[0021] Figure 1 An application scenario schematic diagram provided for the present application, in the tension stringing process of power engineering construction, the system provided by the present application is applied, the traction force, oscillation and wind load are monitored in real time, the system instability and load risk are predicted, early warning and active intervention are realized, thereby improving the construction safety and adaptability to complex environments.

[0022] Specifically, the system provided by the application is applied to any server, the server interacts with a sensor network, obtains a traction board information set provided by the sensor network, constructs an active defense system for construction safety, generates a hierarchical early warning and self-adaptive control strategy through early prediction and intervention of dynamic risks, reduces the accident rate, and outputs a dynamic safety log of the whole process of the tensioning to construction workers, which is convenient for subsequent analysis and improvement and improves the construction management efficiency.

[0023] The specific implementation can refer to the following embodiments.

[0024] Figure 2 The flowchart of the power engineering construction safety guarantee monitoring system based on big data provided by an embodiment of the application, the system of the embodiment can be applied to the server in the above scene. As shown in the figure, the system comprises: Figure 2 S201, obtain a traction board information set in the tensioning process, based on the traction board information set, analyze the wave impedance potential of the single traction rope in front of the traction board and the damping attenuation characteristics of the multi-bundle conductor behind the traction board, and obtain a traction force dynamic information set.

[0025] The traction board information set can be a state parameter set of the traction board and its related components in the tensioning process, which is collected by the sensor network deployed on the construction site. The wave impedance potential can be a physical quantity used to represent the impedance characteristics and energy potential of the traction rope in the wave propagation process. The damping attenuation characteristics can be the characteristics of the vibration energy dissipation of the multi-bundle conductor due to internal friction and air resistance in the vibration process. The traction force dynamic information set can be a set of information used to describe the dynamic changes of the traction force in the tensioning process.

[0026] Specifically, in the power engineering construction, tensioning is a key link of erecting the conductor, and the traction board, as a component connecting the traction rope and the conductor, directly determines the tensioning safety and efficiency. The monitoring of the traction force is often based on a static or simplified dynamic model, which cannot accurately capture the complex dynamic behavior of the traction rope and the conductor, such as stress wave propagation and vibration attenuation, resulting in that safety hazards such as wire breakage or equipment overload cannot be identified in time. By obtaining the traction board information set and deeply analyzing the wave impedance potential of the traction rope and the damping attenuation characteristics of the conductor, a mapping from the original sensor data to the traction force dynamic characteristics can be established, and the real-time change mechanism of the traction force can be revealed. This step provides a comprehensive perception of the mechanical state of the tensioning process, can early warn the traction force anomaly, avoid the chain failure caused by dynamic fluctuations, and at the same time provides reliable data for the subsequent steps, ensuring the adaptability and accuracy of the whole monitoring system.

[0027] ​S202, based on the set of dynamic traction force information, analyze the process of the oscillation chain reaction caused by the superposition and interference of multiple stress waves at the traction board under the influence of the sudden jump, and obtain the set of dynamic instability information of the traction board.

[0028] The sudden jump can be a phenomenon that the traction force on the traction board changes in a short time due to the instantaneous action of the traction machine, the blocking of the conductor or the sudden change of external load during the tensioning process. The multiple stress waves can be stress waves excited in the traction rope and the multi-split conductor and propagating in different directions. The oscillation chain reaction can be a continuous oscillation effect formed by repeated reflection and transmission of stress waves among the traction board, the traction rope and the conductor due to the difference in mechanical properties of the three, which further leads to the gradual increase of the vibration amplitude of the traction board and the continuous deterioration of the stress state. The set of dynamic instability information of the traction board can be a set of information for characterizing the stability state and instability risk of the traction board under the influence of the oscillation chain reaction.

[0029] Specifically, during the tensioning process, the sudden jump of the traction force is a common phenomenon, but the superposition and interference of the multiple stress waves excited thereby can trigger the oscillation chain reaction, leading to the dynamic instability of the traction board, and in severe cases, causing conductor breakage, equipment damage or construction interruption. The existing monitoring system often ignores the dynamic interference effect of stress waves or uses a linear model for simplified processing, which cannot predict the occurrence and evolution of the chain reaction, making it difficult to take intervention measures before the accident. By analyzing the process of the oscillation chain reaction triggered by the superposition and interference of multiple stress waves, the dynamic instability risk of the traction board can be identified, and the conduction mechanism from local fluctuations to system instability can be revealed. This step fills the gap in dynamic instability prediction in the prior art, enabling the system to provide early warning of the risks brought by complex fluctuation interactions.

[0030] S203, based on the set of dynamic instability information of the traction board, analyze the dynamic wind load modulation law of the traction board as a non-streamline aerodynamic disturbance body in motion on the sub-conductor in the wake region, and obtain the set of aerodynamic interference information.

[0031] The non-streamline aerodynamic disturbance body can refer to the vortex and turbulence generated by the traction board when it moves in the air due to its non-smooth shape, which disturbs the surrounding airflow. This definition is based on the principle of aerodynamics. The dynamic wind load modulation law can be the dynamic influence law of the traction board on the wind load of the sub-conductor in the wake region. The set of aerodynamic interference information can be a set of information for describing the change of the wind load of the sub-conductor under the effect of aerodynamic interference.

[0032] Specifically, during the process of stringing, the traction plate moves at a certain speed, and its non-streamlined structure will disturb the airflow, causing the trailing wake area conductor to bear dynamic wind load. This aerodynamic interference may cause conductor vibration, galloping or fatigue damage, affecting the stringing accuracy and construction safety. The existing technology usually ignores the aerodynamic effect of the traction plate or uses a steady-state wind load model, which cannot accurately reflect the changes of dynamic wind load modulation in complex environments, leading to incomplete risk assessment. By analyzing the dynamic wind load modulation law of the traction plate as a non-streamlined aerodynamic disturbance body on the trailing wake area conductor, the influence of aerodynamic interference can be quantified, and the mechanism of wind-structure interaction can be revealed. This step considers the aerodynamic-structural coupling effect, enabling the system to comprehensively assess wind load risks and provide accurate input for subsequent hazard point positioning.

[0033] S204, based on the set of aerodynamic interference information, dynamically positioning the instantaneous hazard point and predicting the load evolution trajectory, generating a hierarchical warning and adaptive control strategy, and outputting the stringing whole-process dynamic safety log.

[0034] The instantaneous hazard point can be a high-risk position or time point that suddenly appears during the process of stringing. The load evolution trajectory can be the changing path of the load over time or space. The hierarchical warning and adaptive control strategy can be warning information and corresponding control measures according to risk level division. The stringing whole-process dynamic safety log can be a log file that records safety-related data throughout the stringing process.

[0035] Specifically, during the process of stringing, the hazard point may appear instantaneously, and if not timely positioned and addressed, it may cause equipment failure, personnel injury or project delay. Existing systems often lack dynamic positioning and prediction capabilities, and the warning strategy is single, which cannot adapt to rapid changes in complex working conditions, leading to response lag. By dynamically positioning the instantaneous hazard point and predicting the load evolution trajectory, risks can be identified in real time, and a hierarchical warning and adaptive control strategy can be generated to ensure construction safety. At the same time, the whole-process dynamic safety log is output to provide complete data support for post-analysis and optimization. This step realizes closed-loop control from data acquisition to decision output, improving the intelligence and adaptability of the system.

[0036] By the way provided by the embodiment, the dynamic behavior of the traction force can be accurately captured, the perception ability of the mechanical state of the stringing process is improved, the early warning is provided, the construction risk is reduced, and the adaptability to complex environmental changes is enhanced. Further, by analyzing the oscillation chain reaction process, the system can predict the dynamic instability trend of the traction plate, realize early intervention, prevent the accident from expanding, and improve the construction safety and stability. In addition, by analyzing the dynamic wind load modulation law, the system can identify the influence of aerodynamic interference on the sub-conductor, reduce the risk of wind-induced vibration, and improve the adaptability to the construction environment. Finally, by dynamically positioning the instantaneous dangerous point and predicting the load evolution track, the system can respond to the risk in time, generate a targeted regulation strategy, reduce the accident rate, and the safety log provides complete historical data, which is convenient for subsequent analysis and improvement, and improves the construction management efficiency.

[0037] In some embodiments, the traction plate information set includes a traction plate spatial pose information set, a traction rope and each sub-conductor tension information set, and a stringing running speed gear parameter; based on the traction plate spatial pose information set, in combination with the stringing running speed gear parameter, the wave impedance mismatch degree and the damping cooperativity change caused by the spatial configuration difference between the front traction rope and the rear multi-split conductor in the movement process of the traction plate are analyzed, to obtain a traction dynamic impedance set; based on the traction dynamic impedance set, in combination with the traction rope and each sub-conductor tension information set, the reflection and transmission energy distribution relationship of the tension wave at the impedance mismatch interface, and the dissipation and delay effect of the multi-split conductor on the wave energy due to the damping characteristics are analyzed, to obtain a stress interference potential set; based on the stress interference potential set, the traction force is analyzed to be mutually enhanced or mutually offset when the multiple stresses are superimposed at the traction plate, so as to quantify the potential impact amplification or stable inhibition effect on the traction force, to obtain a traction force dynamic information set.

[0038] The traction board spatial pose information set can refer to position and attitude data of the traction board in three-dimensional space collected by an inertial measurement unit installed on the traction board. The traction rope and each sub-conductor tension information set can be the force condition of the conductor. The stringing operation speed gear parameter can refer to the running speed level of the stringing equipment set by the control system, which is used to control the progress of the stringing process. The traction dynamic impedance set can be a set of information representing the degree of wave impedance mismatch between the front single traction rope and the rear multi-split conductor due to differences in spatial configuration during the movement of the traction board, as well as the coordinated variation law of the damping characteristics of the two. The tension wave can be a mechanical wave in the traction rope and multi-split conductor during the tension stringing process, caused by factors such as traction board movement, equipment start-stop, external disturbance, etc. The impedance mismatch interface can be the connection interface of the front single traction rope and the rear multi-split conductor at the traction board. Due to differences in structure, material distribution, mechanical properties, etc. between the traction rope and the multi-split conductor, the tension wave cannot be completely matched and propagated at this interface, resulting in reflection and transmission phenomena in a specific area. The reflected energy can be the energy reflected back by the stress wave at the impedance mismatch interface. The transmitted energy can be the energy of the stress wave that continues to propagate through the impedance mismatch interface. The multi-split conductor damping attenuation characteristic can be the inherent characteristic of the multi-split conductor in which the wave energy is gradually consumed and the amplitude is gradually reduced due to factors such as internal friction of the conductor material, mutual friction between sub-conductors, air resistance, etc. The dissipation hysteresis effect of wave energy can be that the dissipation process of the multi-split conductor to the wave energy of the tension wave does not occur immediately, but there is a certain time delay, i.e. after the tension wave enters the conductor, the energy is not immediately completely dissipated, but gradually attenuates over time. The stress interference potential set can be a set of information reflecting the energy accumulation potential of the stress wave during interference.

[0039] Specifically, in the tension stringing process of power engineering construction, the traction plate is a key connecting component. The front traction rope and the rear multi-split conductor are abnormal due to structural differences, which causes wave impedance mismatch and damping incoordination, leading to uneven energy distribution of tension wave reflection and transmission, and further causing traction force mutation and oscillation risk. If not analyzed in detail, it may cause serious accidents such as traction plate instability, conductor breakage or equipment damage. The above problems are solved by the following methods: through multi-sensor data fusion means, the spatial pose information set of the traction plate is collected by using inertial measurement units (such as GPS and gyroscope sensors), and the traction rope and the tension information set of each sub-conductor are obtained by combining the tension sensor (such as strain gauge sensor), and the stringing running speed gear parameters (such as low speed gear or high speed gear), the wave impedance mismatch degree (such as impedance ratio change) and the damping cooperativity change caused by the spatial configuration difference between the front single traction rope and the rear multi-split conductor are calculated by using the wave motion theory analysis method, and the traction dynamic impedance set is obtained; then based on the impedance set and the tension information set, the energy distribution model is used to analyze the reflection and transmission energy distribution relationship (such as reflection energy proportion and transmission energy proportion) of the tension wave at the impedance mismatch interface, and the damping dissipation model is introduced to evaluate the dissipation delay effect (such as energy attenuation delay time) of the multi-split conductor on the wave energy, and the stress interference potential set is obtained; finally, through the interference analysis means, it is evaluated whether the multiple stresses tend to mutually enhance or mutually offset when superimposed at the traction plate, so as to quantify the potential impact amplification or smooth inhibition effect on the traction force, and generate the traction force dynamic information set.

[0040] Through the way provided by the embodiment, the wave impedance energy potential and the damping attenuation characteristics can be monitored and analyzed in real time, the change of the traction force is dynamically quantified, data support is provided for preventing out of control, the safety and stability of the stringing process are ensured, and the shortcomings of the existing method of only focusing on static tension and ignoring dynamic wave interference are made up, and the adaptability and reliability of the overall monitoring system are improved.

[0041] In some embodiments, based on the traction dynamic impedance set, the instantaneous difference between the front traction rope and the rear multi-split conductor wave impedance is analyzed, which causes the energy distribution proportion to present an asymmetric jump when the tension wave is reflected and transmitted at the traction plate, and a dynamic asymmetric energy set is obtained; based on the traction rope and the tension information set of each sub-conductor, the damping attenuation characteristics of the rear multi-split conductor are analyzed to the dissipation process of the transmitted wave energy, the dissipation process has variable delay in time relative to the wave input, and is differentially distributed in space due to the uneven tension of each sub-conductor, and a time-space difference dissipation set is obtained; based on the dynamic asymmetric energy set, combined with the time-space difference dissipation set, the dynamic interference mode formed by the time difference and intensity difference acting on the multi-split conductor between the energy quickly reflected back to the traction plate and the transmitted energy delayed acting on the traction plate after differential dissipation is analyzed, whether the energy tends to periodically accumulate and amplify at the traction plate, or tends to gently dissipate, and a stress interference potential set is obtained.

[0042] The energy distribution relationship can be a proportion rule of reflected energy and transmitted energy of the tension wave at the impedance mismatch interface. The multi-split conductor can be a conductor structure commonly used in power engineering tension stringing, which is composed of multiple sub-conductors. The damping characteristic can be an inherent property of the multi-split conductor to consume fluctuation energy, which dissipates the tension wave energy through the internal friction of the conductor material, the friction between the sub-conductors, and other ways, affecting the attenuation speed of energy transmission. The fluctuation energy can refer to the mechanical energy carried by the tension wave, which is related to the conductor tension, fluctuation amplitude, etc., and is the key energy source that causes conductor vibration and instability of the traction plate. The dissipation hysteresis effect can be a phenomenon that the dissipation process of fluctuation energy lags behind the input of fluctuation in time due to the damping characteristic of the multi-split conductor.

[0043] Specifically, in the tension stringing process of power engineering construction, the traction plate as a key connecting component directly affects the safety of stringing, and the existing monitoring method often ignores the dynamic stress interference caused by wave impedance mismatch and damping dissipation, and cannot predict the oscillation risk caused by energy accumulation in real time, thereby causing instability of the traction plate, intensification of sub-conductor vibration, and even equipment damage. The above problems are solved by the following method: by using a wave impedance analysis method, the instantaneous difference of wave impedance between the front traction rope and the rear multi-split conductor is identified based on the traction dynamic impedance set, the asymmetric jump rule of the reflection and transmission energy distribution ratio of the tension wave at the impedance mismatch interface is analyzed by using the energy conservation principle (for example, when the wave impedance difference reaches a certain threshold such as 0.5, the reflection energy ratio can increase to 60%), and thus a dynamic asymmetric energy set is obtained; at the same time, a damping characteristic modeling method is used, the damping attenuation characteristics of the multi-split conductor caused by material characteristics and uneven tension are analyzed based on the tension information set of the traction rope and each sub-conductor, and the variable delay of the transmission wave energy dissipation process in time and the differential distribution in space are described by time domain and space domain analysis methods (for example, the delay time can be in the range of 0.1 seconds to 0.5 seconds, and the dissipation speed of the sub-conductor with higher tension is faster), and thus a time-space difference dissipation set is obtained; further, the dynamic asymmetric energy set and the time-space difference dissipation set are combined, a dynamic interference analysis method is used to evaluate the interference mode formed by the reflection energy and the transmission energy at the multi-split conductor due to the time difference and the intensity difference, and a pattern recognition method is used to judge whether the energy tends to accumulate and amplify periodically (for example, the accumulation intensity can exceed the safety threshold) or tends to be flat and dissipated at the traction plate, and thus a stress interference potential set is obtained.

[0044] By the way provided by the embodiment, the energy asymmetric distribution and the time-space delay effect of the damping dissipation caused by the wave impedance difference can be analyzed in depth, the stress interference potential can be quantified, the energy accumulation or dissipation trend can be identified in advance, data support can be provided for subsequent hierarchical early warning and adaptive regulation, chain reaction accidents can be effectively avoided, and the real-time and reliability of construction safety guarantee can be improved.

[0045] In some embodiments, based on the stress interference potential set, when the reflected energy and the transmitted energy tend to be synchronized due to the time difference, periodic energy accumulation is triggered at the traction plate during the dynamic interference process, forming a vibration amplification effect, obtaining energy accumulation instantaneous intensity and energy accumulation duration information; based on the energy accumulation instantaneous intensity, combined with the energy accumulation duration information, the initial dynamic instability process of the traction plate under the energy impact exceeding the stability threshold is analyzed, the initial dynamic instability process is characterized by abnormal mutation of the spatial pose of the traction plate and sudden rise of the tension of a single sub-conductor; based on the initial dynamic instability process, the sag change caused by the sudden change of the tension of a single sub-conductor is analyzed, breaking the original aerodynamic balance between the split conductors, and then inducing a chain reaction process in which adjacent sub-conductors enter an abnormal vibration state one after another, obtaining a traction plate dynamic instability information set.

[0046] The oscillation chain reaction can be a chain reaction in which adjacent sub-conductors oscillate one after another triggered by the initial instability. The time difference can be the time difference between the reflected energy and the transmitted energy reaching the traction plate. The traction force tends to be synchronized can be that the reflected energy and the transmitted energy are aligned in time, resulting in the traction force acting at the same time. Periodic energy accumulation can be the phenomenon of periodic accumulation of energy at the traction plate. The vibration amplification effect can be the effect that the energy accumulation leads to an increase in the vibration amplitude. The energy accumulation instantaneous intensity can be the intensity value of the energy accumulation at a certain moment. The energy accumulation duration information can be the time period information of the energy accumulation duration. The stability threshold can be the maximum energy impact value that the traction plate can withstand to maintain a stable state. The energy impact can be an energy impact exceeding the stability threshold. The initial dynamic instability process can be the process in which the traction plate begins to destabilize under the energy impact. The abnormal mutation of the spatial pose of the traction plate can be the sudden change of the position and attitude of the traction plate in space. The sudden rise of the tension of a single sub-conductor can be the sudden increase of the tension of a single sub-conductor. The sag change can be the change in sag of the sub-conductor caused by the change in tension. The aerodynamic balance between the split conductors can be the balance state maintained by the multiple split conductors under the action of the airflow. The adjacent sub-conductor can be other sub-conductors adjacent to the initial instability sub-conductor. The abnormal vibration state can be the abnormal vibration behavior of the sub-conductor. The chain reaction process can be a process in which the instability phenomenon propagates among the sub-conductors one after another.

[0047] Specifically, in the power engineering tension stringing construction, the traction plate is a component connecting the front single traction rope and the rear multi-bundle conductor, and its running stability directly determines the safety of the stringing construction. The existing technology has two key defects in analyzing the stability of the traction plate: one is that only the independent action of a single stress is concerned, and the superposition interference effect of multiple stress waves at the traction plate caused by the sudden jump event is ignored. The superposition interference often forms periodic energy accumulation, and the energy peak value may be much higher than the action strength of a single stress, which becomes a direct inducement of the instability of the traction plate. The second is that the chain reaction after the initial instability is not paid attention to, that is, the change of sag caused by the sudden change of tension of the single sub-conductor breaks the aerodynamic balance between the bundle conductors, and then induces abnormal vibration of the adjacent sub-conductor. This chain reaction of oscillation can quickly spread the unstable state from the local to the whole, causing the risk level to rise sharply. The step solves the above problems by the following method: based on the stress interference potential set, the method of combining dynamic mechanical analysis with energy accumulation modeling is used to analyze the periodic energy accumulation phenomenon caused by the reflection energy and transmission energy at the traction plate when the traction force tends to be synchronized due to the time sequence difference in the dynamic interference process. The energy accumulation instantaneous strength (such as 600N) and energy accumulation continuous cycle information (such as 3 seconds) are obtained by real-time detection means of stress wave superposition strength. Then, the structural mechanics characteristic analysis method is used to study the initial dynamic instability process of the traction plate under the energy impact exceeding the stability threshold. The process specifically shows the abnormal mutation of the spatial pose of the traction plate (such as a horizontal direction offset of 12 cm) and the sudden rise of the tension of the single sub-conductor (such as from 350N to 700N). Then, the multi-body dynamics simulation technology and chain reaction tracking method are used to analyze how the change of sag caused by the sudden change of tension of the single sub-conductor (such as an increase of 60 cm) breaks the original aerodynamic balance between the bundle conductors, and then induces the chain reaction process of the adjacent sub-conductor entering the abnormal vibration state (such as the vibration frequency rising from 3Hz to 10Hz and the vibration amplitude increasing from 5cm to 25cm). Finally, through multi-dimensional information integration and feature extraction technology, the oscillation chain reaction strength, traction plate pose change data and each sub-conductor vibration state parameter information are analyzed to form the traction plate dynamic instability information set which comprehensively reflects the dynamic instability of the traction plate.

[0048] Through the way provided by the embodiment, the dynamic stability of the traction plate in the tension stringing process can be monitored in real time, the energy accumulation and vibration amplification phenomenon caused by stress wave superposition interference can be identified in time, the initial instability risk can be warned, the abnormal vibration of the adjacent sub-conductor can be predicted through the analysis of the chain reaction process, the instability diffusion can be prevented, and the safety and reliability of the whole stringing system can be improved. In addition, the data support is provided to generate a hierarchical warning and adaptive control strategy, optimize the construction process, reduce potential accidents, ensure the smooth progress of the project, and enhance the adaptability of the system to complex dynamic working conditions.

[0049] In some embodiments, based on the initial dynamic instability process, the sudden rise of the tension of a single sub-conductor is analyzed to obtain the dynamic tension difference information between sub-conductors, which is caused by the change in sag and the asymmetric pulling effect on adjacent sub-conductors; based on the dynamic tension difference information between sub-conductors, the non-synchronous oscillation mode excited by the uneven tension of adjacent sub-conductors is analyzed to obtain the multi-conductor non-synchronous oscillation information; based on the multi-conductor non-synchronous oscillation information, the oscillation energy transfer and superposition process caused by non-synchronous oscillation in the split conductor group is analyzed to obtain the oscillation chain reaction strength information; and based on the oscillation chain reaction strength information, the continuous reaction of the chain reaction on the spatial pose of the traction plate is analyzed to obtain the traction plate dynamic instability information set.

[0050] The aerodynamic balance can be a stable aerodynamic distribution state formed by the multi-split conductor under the action of wind load. The non-synchronous oscillation mode can be a vibration form that each sub-conductor exhibits in the vibration of the multi-split conductor, which has differences in vibration frequency, oscillation phase, vibration waveform or amplitude at the same time. The dynamic tension difference information between sub-conductors can be the instantaneous difference in tension value between any two or more sub-conductors and the law of its evolution over time.

[0051] Specifically, during the tensioning process, if the dynamic instability of the traction board is not timely identified and intervened, it may cause systemic oscillation of the multi-bundle conductor, eventually leading to conductor breakage, equipment damage, or construction interruption, etc. The sudden change in tension of a single sub-conductor will destroy the aerodynamic balance of the bundle conductor group through changes in sag. This destruction is not an isolated event, but will induce a chain reaction through dynamic coupling between adjacent sub-conductors, causing local instability to rapidly spread to the entire conductor system. Existing technologies often only focus on single-point tension or displacement monitoring, lack in-depth analysis of the chain reaction process, and cannot predict the evolution path and potential risks of instability. The present step solves the above problems by the following methods: first, the sensor network (such as tension sensors and displacement sensors) is used to monitor the sudden change data (such as the tension value suddenly increasing from 5kN to 15kN) of the single sub-conductor tension in the initial dynamic instability process in real time, and the physical modeling method is used to analyze the sag change (such as the sag increasing by 0.3 meters) caused by the sudden change of tension. This analysis is based on the conductor mechanics model, which identifies the asymmetric pulling effect of sag change on adjacent sub-conductors by calculating the nonlinear relationship between tension and sag; then, the system uses multi-body dynamics simulation method to simulate the process of the sag change breaking the aerodynamic balance between the bundle conductors, focuses on analyzing the non-synchronous oscillation mode (such as the adjacent sub-conductors appearing a phase difference of 30 degrees of oscillation) excited by the uneven tension, and traces the transmission and superposition of the non-synchronous oscillation in the bundle conductor group through the energy transmission model, so as to quantify the chain reaction strength (such as the oscillation energy growing exponentially); finally, the system integrates the dynamic tension difference between the sub-conductors, the non-synchronous oscillation information and the chain reaction strength, and uses data fusion technology to generate the traction board dynamic instability information set. This information set reflects the continuous reaction of the chain reaction on the spatial pose of the traction board (such as the traction board offset angle increasing to 5 degrees), providing input for subsequent aerodynamic interference analysis and warning strategies.

[0052] By the way provided by the present embodiment, the diffusion risk of traction board instability can be identified early, the systemic oscillation accident of multi-bundle conductor can be effectively prevented, and the construction safety and reliability can be improved; at the same time, this process enhances the adaptability of the monitoring system to complex physical field coupling, provides decision basis for dynamic regulation, and reduces the demand for human intervention.

[0053] In some embodiments, based on the set of dynamic instability information of the towboard, in combination with the set of spatial pose information of the towboard, the relative position change of the towboard with the two side towers when moving in the file is analyzed to obtain the spatial configuration ratio information of the towboard; based on the spatial configuration ratio information of the towboard, in combination with the chain reaction strength information, the spatial modulation effect of the change of the spatial configuration ratio of the towboard is analyzed to obtain the spatial distribution information of the chain reaction strength; based on the spatial distribution information of the chain reaction strength, the dynamic influence change law of the wake vortex excited by the non-streamlined shape towboard in the moving process on the rudder of the towboard and the balance weight of the towboard is analyzed to obtain the set of dynamic wake mode information; based on the set of dynamic wake mode information, in combination with the multi-conductor non-synchronous oscillation information, the coupling vibration risk distribution between the dynamic wake and the multi-conductor non-synchronous oscillation due to different spatial positions is analyzed to obtain the set of aerodynamic interference information.

[0054] The spatial configuration ratio information of the towboard can be the ratio information of the length of the tow rope in front of the towboard to the length of the multi-split conductor behind the towboard. The chain reaction strength information can be information quantifying the degree of oscillation energy transfer and superposition in the split conductor group. The non-streamlined shape can be a structural feature of the towboard, which means that the shape does not have a streamlined design to reduce air resistance, and will excite a wake vortex in movement, which is an inherent structural attribute of the towboard. The wake vortex can be a rotating air flow area formed behind the towboard when it moves. The rudder can be a component on the towboard used to adjust the direction and stabilize the attitude. The balance weight can be a component on the towboard used to balance the weight and suppress abnormal swing. The set of dynamic wake mode information can be a set of information classifying and characterizing the characteristics of the wake vortex of the towboard in different moving stages (early, middle, and late). The multi-conductor non-synchronous oscillation information can be information describing the vibration frequency and phase difference of each sub-conductor due to uneven tension. The coupling vibration risk distribution can be the probability and intensity distribution of dangerous vibration caused by the interaction of dynamic wake and multi-conductor non-synchronous oscillation at different spatial positions.

[0055] Specifically, in the tension stringing process of power engineering construction, the traction plate as a key connecting component directly determines the stringing safety and efficiency. Due to the non-streamline shape of the traction plate, it will act as a vortex excitation body in the moving process, and these vortices interact with the non-synchronous oscillation of the sub-conductor, which may exacerbate the aerodynamic disturbance, cause conductor galloping, breakage, and even systemic out-of-control accidents. The existing monitoring system often only focuses on static or single-point risks, ignores the dynamic modulation effect of spatial configuration changes on aerodynamic disturbance in the moving process of the traction plate, and cannot accurately predict the instantaneous dangerous points and load evolution trajectory. Especially in complex environments such as wind speed changes or conductor tension mutations, the evaluation deviation may amplify the safety risk. The above problems are solved by the following methods: based on the traction plate dynamic instability information set, combined with the traction plate spatial pose information set, the spatial geometric analysis method is used to analyze the relative position change of the traction plate in the file, and the length ratio evolution process of the front and back lines (such as the ratio from 1:5 to 5:1) caused by the traction plate is obtained. Get the traction plate spatial configuration ratio information; based on the traction plate spatial configuration ratio information, combined with the oscillation chain reaction intensity information, the spatial modulation effect of the traction plate spatial configuration ratio change on the oscillation chain reaction intensity (such as the configuration ratio change causing the reaction intensity to be distributed from low to high in space) is analyzed by spatial modulation analysis method, and the chain reaction intensity spatial distribution information is obtained; based on the chain reaction intensity spatial distribution information, the dynamic influence change law of the wake vortex excited by the non-streamline shape of the traction plate in the moving process on the rudder of the traction plate and the balance hammer (such as the wake vortex frequency evolving from low frequency high amplitude to high frequency low amplitude) is analyzed by computational fluid dynamics simulation method, and the dynamic wake mode information set is obtained; based on the dynamic wake mode information set, combined with the multi-conductor non-synchronous oscillation information, the coupling vibration risk distribution (such as the risk value from low to high distribution) between the dynamic wake and the multi-conductor non-synchronous oscillation due to different spatial positions is analyzed by the coupling vibration risk evaluation method, and the aerodynamic disturbance information set is obtained.

[0056] By the way provided by the embodiment, the aerodynamic disturbance risk in the moving process of the traction plate can be accurately quantified, the high-risk area of coupling vibration can be dynamically identified, and input can be provided for hierarchical early warning and adaptive regulation, thereby effectively reducing the safety risk in the stringing process, improving the reliability and efficiency of engineering construction, and enhancing the adaptability of the system to complex environmental changes.

[0057] In some embodiments, based on the set of aerodynamic interference information, in combination with the information of the spatial configuration ratio of the towboard, the information of the change of the spatial configuration ratio with the position is analyzed during the whole process of the towboard moving from the departure tower to the target tower: when the towboard is close to the departure tower and the length of the single tow rope in front is much longer than that of the multi-split conductor in back, the characteristics of the low-frequency high-amplitude aerodynamic load generated by the non-streamlined towboard due to the wind load acting on the rudder are analyzed, in combination with the characteristics of the high-frequency small-amplitude constraint oscillation generated by the wind load acting on the counterweight, to obtain the set of early dynamic wake mode information; when the towboard moves to the midpoint between the departure tower and the target tower and the length of the single tow rope in front is similar to that of the multi-split conductor in back, the characteristics of the aerodynamic elastic vibration generated by the non-streamlined towboard due to the wind load acting on the rudder are analyzed, in combination with the characteristics of the large-amplitude swing generated by the wind load acting on the counterweight, to obtain the set of medium-term dynamic wake mode information; when the towboard is close to the target tower and the length of the single tow rope in front is much shorter than that of the multi-split conductor in back, the characteristics of the high-frequency low-amplitude aerodynamic load generated by the non-streamlined towboard due to the wind load acting on the rudder are analyzed, in combination with the characteristics of the low-frequency swing generated by the wind load acting on the counterweight, to obtain the set of late dynamic wake mode information; the set of early dynamic wake mode information, the set of medium-term dynamic wake mode information, and the set of late dynamic wake mode information are integrated to obtain the set of dynamic wake mode information.

[0058] The chain reaction intensity spatial distribution information can be the intensity distribution of the oscillation chain reaction in space caused by the dynamic instability of the towboard. The moving process can be the whole process of the towboard moving from the departure tower to the target tower during the tension stringing process. The dynamic influence change law can be the law of the influence of the wake vortex on the rudder and the counterweight changing with the position. The departure tower can be the tower at the starting end of the tension stringing. The target tower can be the tower at the target end of the tension stringing. The change of the spatial configuration ratio with the position can be the change of the configuration ratio with the movement of the towboard. The set of early dynamic wake mode information can be the wake mode characteristics when the towboard is close to the departure tower. The set of medium-term dynamic wake mode information can be the wake mode characteristics when the towboard is at the intermediate position. The set of late dynamic wake mode information can be the wake mode characteristics when the towboard is close to the target tower.

[0059] Specifically, in the power engineering tension stringing construction, the traction plate as a traction component, its non-streamline shape will inevitably produce aerodynamic disturbance in the moving process, forming a wake vortex, and the dynamic influence of the wake vortex on the rudder and the counterweight of the traction plate is directly related to the stability of the traction plate and the safety of the whole stringing process. The previous analysis has obtained the chain reaction intensity spatial distribution information, but it does not refine the influence characteristics of the wake vortex in different stages of the traction plate movement. Since the length ratio (spatial configuration ratio) of the front traction rope to the rear multi-split conductor changes constantly in the whole process from the starting tower to the target tower, the action mode, strength, frequency, etc. of the wind load on the rudder and the counterweight will all be different. If a unified analysis mode is used, the dynamic change law in different stages cannot be captured. The following methods are used to solve the above problems: based on the aerodynamic interference information set and the spatial configuration ratio information of the traction plate, through aerodynamic analysis and vibration analysis means, the change law of the spatial configuration ratio of the traction plate from the starting tower to the target tower is analyzed. When the traction plate approaches the starting tower, the wind tunnel test simulation and computational fluid dynamics method are used to analyze the low-frequency high-amplitude aerodynamic load characteristics (such as frequency lower than 1Hz and amplitude higher than 10N) generated by the wind load acting on the rudder, and the high-frequency micro-amplitude constraint oscillation characteristics (such as frequency higher than 5Hz and amplitude lower than 0.5N) of the balance weight are monitored by the sensor, to obtain the early dynamic wake mode information set; when the traction plate moves to the midpoint, the aerodynamic elastic vibration characteristics of the rudder are analyzed by using the aerodynamic elastic coupling analysis method, and the large-amplitude swing characteristics (such as swing amplitude greater than 5 degrees) of the balance weight are captured by using the image recognition technology, to obtain the medium-term dynamic wake mode information set; when the traction plate approaches the target tower, the high-frequency low-amplitude aerodynamic load characteristics (such as frequency higher than 10Hz and amplitude lower than 2N) of the rudder are analyzed by using the spectrum analysis method, and the low-frequency swing characteristics (such as frequency lower than 0.5Hz) of the balance weight are recorded by using the inertial measurement unit, to obtain the late dynamic wake mode information set; finally, all the information sets are integrated to form the dynamic wake mode information set.

[0060] By the way provided by the embodiment, the wake mode characteristics of the traction plate at different positions can be comprehensively mastered, the dynamic influence of the wake vortex on the rudder and the counterweight can be accurately understood, thereby providing a reliable basis for dynamically positioning the instantaneous dangerous point and predicting the load evolution trajectory, effectively improving the safety monitoring capability of the tension stringing process, reducing the construction risk, and ensuring the smooth progress of the project.

[0061] In some embodiments, based on the early dynamic wake mode information set, the vibration coupling risk between the low-frequency high-amplitude aerodynamic load characteristics of the rudder and the low-frequency oscillation mode of the sub-conductor near the towboard due to the similar frequencies is analyzed to obtain a first interval coupling risk information set; based on the medium-term dynamic wake mode information set, the aerodynamic elastic vibration characteristics of the rudder and the high-amplitude non-synchronous oscillation of each sub-conductor at the peak of the chain reaction intensity when the balance weight swings greatly are analyzed to obtain a second interval coupling risk information set; based on the late dynamic wake mode information set, the beat coupling risk between the high-frequency low-amplitude aerodynamic load characteristics of the rudder and the low-frequency residual oscillation of the balance weight attenuated by strong damping action due to the staggered frequencies is analyzed to obtain a third interval coupling risk information set; the first interval coupling risk information set, the second interval coupling risk information set and the third interval coupling risk information set are integrated to obtain an aerodynamic interference information set.

[0062] The early dynamic wake mode information set can be a collection of information when the towboard is close to the departure tower, the front single tow rope is much longer than the rear multi-split conductor, the rudder generates low-frequency high-amplitude aerodynamic load characteristics, and the balance weight generates high-frequency micro-amplitude constraint oscillation characteristics. The medium-term dynamic wake mode information set can be a collection of information when the towboard moves to the midpoint between the departure tower and the target tower, the front single tow rope is similar in length to the rear multi-split conductor, the rudder generates aerodynamic elastic vibration characteristics, and the balance weight appears large swing characteristics. The late dynamic wake mode information set can be a collection of information when the towboard is close to the target tower, the front single tow rope is much shorter than the rear multi-split conductor, the rudder generates high-frequency low-amplitude aerodynamic load characteristics, and the balance weight generates low-frequency oscillation characteristics. The vibration coupling risk can be the risk of energy transfer leading to vibration amplification when the frequencies of two or more vibration systems are similar. The interference coupling risk can be the risk of producing severe interference leading to vibration amplitude increase when the energy of two or more vibration systems interacts and superimposes. The beat coupling risk can be the risk of beat phenomenon leading to periodic amplitude modulation when the frequencies of two vibration systems are staggered. The first interval coupling risk information set can be a quantitative information set of vibration coupling risk in the early interval. The second interval coupling risk information set can be a quantitative information set of interference coupling risk in the medium-term interval. The third interval coupling risk information set refers to a quantitative information set of beat coupling risk in the late interval.

[0063] Specifically, in the power engineering tension stringing construction, the oscillation caused by the dynamic instability of the traction plate as a key connecting component and the aerodynamic interference is one of the hidden dangers leading to construction safety accidents. The dynamic instability information set and the dynamic wake mode information set of the traction plate have been obtained, but the coupling effect analysis between the dynamic wake and the multi-conductor non-synchronous oscillation has not been involved. The above problems are solved by the following method: using the method of segmented coupling analysis and risk integration, combining the dynamic wake characteristics and the multi-conductor non-synchronous oscillation law in the moving process of the traction plate, and realizing the coupling risk analysis through the risk correlation identification means: for the low-frequency high-amplitude aerodynamic load characteristics (such as frequency 0.3 Hz, amplitude 6 kN) of the rudder in the early dynamic wake mode information set, and the low-frequency oscillation mode (such as frequency 0.4 Hz, amplitude 0.8 m) of the sub-conductor near the traction plate, frequency matching analysis is carried out, and the vibration coupling risk caused by the similar frequency is identified, forming the first interval coupling risk information set; for the aerodynamic elastic vibration characteristics (such as amplitude 2 kN-4 kN alternately) of the rudder and the large swing characteristics (such as 30° angle, 1.5 m stroke) of the balance weight in the middle dynamic wake mode information set, combined with the high-amplitude non-synchronous oscillation (such as amplitude 2.5 m) of each sub-conductor when the chain reaction strength reaches the peak, through energy superposition effect analysis, the severe interference coupling risk caused by energy interaction is identified, forming the second interval coupling risk information set; for the high-frequency low-amplitude aerodynamic load characteristics (such as frequency 12 Hz, amplitude 1.2 kN) of the rudder and the low-frequency swing characteristics (such as frequency 0.8 Hz, angle 8°) of the balance weight in the late dynamic wake mode information set, combined with the low-frequency residual oscillation (such as frequency 0.6 Hz, amplitude 0.3 m) of the sub-conductor attenuated by strong damping effect, through frequency stagger effect analysis, the beat coupling risk caused by frequency difference is identified, forming the third interval coupling risk information set; finally, using the information integration means, the first, second and third interval coupling risk information sets are systematically summarized to form the aerodynamic interference information set which comprehensively reflects the coupling risk distribution in different construction stages.

[0064] By the way provided by the embodiment, the coupling vibration risk distribution between the dynamic wake and the multi-conductor non-synchronous oscillation in the moving process of the traction plate can be comprehensively analyzed, and the specific risk types in different space intervals can be accurately identified, thereby providing reliable basis for dynamically positioning the instantaneous dangerous point and predicting the load evolution track. This helps to generate more accurate hierarchical early warning and adaptive control strategies, effectively prevents system instability accidents caused by aerodynamic interference, and improves the safety and reliability of power engineering construction. At the same time, by integrating the multi-interval risk information, detailed stringing whole-process dynamic safety log can be output to provide decision support for construction management.

[0065] In some embodiments, based on the set of aerodynamic interference information, the instantaneous intensity and spatial distribution characteristics of each vibration coupling risk in the set of first interval coupling risk information, the set of second interval coupling risk information and the set of third interval coupling risk information are analyzed, the spatial points of vibration coupling risk exceeding a safety threshold are identified, and instantaneous dangerous point positioning information is obtained; based on the instantaneous dangerous point positioning information, the spatial configuration ratio information of the traction plate is combined, the evolution law of the load at the dangerous point with the change of the spatial configuration ratio of the traction plate is analyzed, the evolution path of the load from the current state to the future state is predicted, and load evolution trajectory prediction information is obtained; based on the load evolution trajectory prediction information, the instantaneous intensity of energy accumulation and the energy accumulation duration cycle information are combined, the risk levels of different points in the load evolution trajectory are analyzed, the warning levels are divided according to the risk levels, and a hierarchical warning strategy is generated; based on the hierarchical warning strategy, the set of traction force dynamic information is combined, the warning level is adaptively adjusted according to the speed gear parameter of the laying operation to reduce the risk, and an adaptive control strategy is generated; based on the instantaneous dangerous point positioning information, the load evolution trajectory prediction information, the hierarchical warning strategy and the adaptive control strategy, the safety related events in the laying process are integrated in chronological order, and a laying whole-process dynamic safety log is generated.

[0066] The instantaneous dangerous point positioning information can be related information of the spatial point of vibration coupling risk exceeding the safety threshold. The load evolution trajectory prediction information can be a path prediction result of the evolution of the load at the dangerous point with the change of the spatial configuration ratio of the traction plate.

[0067] Specifically, the tension stringing process in power engineering construction involves complex dynamic interactions, and the instability of the traction plate and aerodynamic interference can trigger an oscillation chain reaction, leading to abnormal vibration and load mutation of the sub-conductor. The existing monitoring system often cannot predict and adaptively control in real time, causing safety hazards and low construction efficiency. The step solves the above problems by the following methods: through risk identification algorithm and spatial analysis means, based on the aerodynamic interference information set, analyze the instantaneous intensity (such as 0.5 vibration coupling risk value) and spatial distribution characteristics of each vibration coupling risk in the first interval coupling risk information set, the second interval coupling risk information set and the third interval coupling risk information set, identify the spatial points whose vibration coupling risk exceeds the safety threshold, and obtain the instantaneous dangerous point positioning information; then, combined with the spatial configuration ratio information of the traction plate, the trajectory prediction model and the configuration ratio analysis means are used to analyze the evolution law of the load at the dangerous point with the change of the spatial configuration ratio of the traction plate, predict the evolution path of the load from the current state to the future state, and obtain the load evolution trajectory prediction information; further, based on the load evolution trajectory prediction information, combined with the energy accumulation instantaneous intensity (such as 1000 joules of energy accumulation value) and the energy accumulation duration cycle information (such as 5 seconds of duration cycle), through the risk assessment matrix and the grade division method, the risk level of different points in the load evolution trajectory is analyzed, and the warning level (such as low, medium and high) is divided according to the risk level, and the graded warning strategy is generated; then, based on the graded warning strategy, combined with the traction force dynamic information set, using the adaptive control algorithm and parameter adjustment means, the stringing running speed gear parameter (such as switching from high gear to medium gear) is adaptively adjusted according to the warning level, so as to reduce the risk, and the adaptive control strategy is generated; finally, based on the instantaneous dangerous point positioning information, the load evolution trajectory prediction information, the graded warning strategy and the adaptive control strategy, through the log generation module and the time sequence integration means, the safety related events in the stringing process are integrated in time sequence, and the dynamic safety log of the whole process of stringing is generated.

[0068] By the way provided by the embodiment, the instantaneous dangerous point is dynamically positioned and the load evolution trajectory is predicted, which can identify potential risks in advance, generate graded warning and adaptive control strategy, effectively prevent the occurrence of traction plate instability and sub-conductor oscillation chain reaction, and improve the safety and stability of the tension stringing process. At the same time, the adaptive control strategy optimizes the stringing running parameters, reduces human intervention, and improves the construction efficiency; the whole process dynamic safety log provides complete data support for construction management and subsequent analysis, and promotes the intelligentization and standardization of power engineering construction.

[0069] In some embodiments, based on the load evolution trajectory prediction information, the interaction force strength of the dynamic wake mode information set and the multi-conductor non-synchronous oscillation information at each point on the evolution trajectory is analyzed to obtain potential interference mode information; based on the potential interference mode information, the energy accumulation under different forces is analyzed to determine whether it presents positive feedback amplification effect or negative feedback suppression effect, to obtain interference phase risk information; based on the interference phase risk information, combined with the energy accumulation sustained period information, it is analyzed whether the sustained positive feedback amplification effect will break through the dissipation limit of damping, thereby triggering structural common vibration, to obtain vibration potential evaluation information; based on the vibration potential evaluation information, combined with the traction plate space configuration ratio information, the chain reaction probability between the common vibration potential and the dynamic instability of the traction plate is analyzed to generate dynamic risk field distribution information; based on the dynamic risk field distribution information, according to the risk field strength, the multi-level early warning grades from diffusion risk to concentrated outbreak risk are divided to generate a hierarchical early warning strategy integrating spatial positioning and evolution trend.

[0070] The potential interference mode information can be the interaction force strength characteristic information of the dynamic wake mode and the multi-conductor non-synchronous oscillation at each point on the evolution trajectory. The interference phase risk information can be risk-related information of the energy accumulation under different forces presenting positive feedback amplification or negative feedback suppression effect. The vibration potential evaluation information can be the evaluation result information of whether the sustained positive feedback amplification effect will break through the damping dissipation limit and trigger structural common vibration. The traction plate space configuration ratio information can be the evolution information of the length ratio of the front and rear clues in the traction plate movement process. The dynamic risk field distribution information can be the spatial distribution information of the chain reaction probability between the common vibration potential and the dynamic instability of the traction plate.

[0071] Specifically, during the tension stringing process, the traction plate, as a key component connecting the front single traction rope and the rear multi-split conductor, its dynamic stability is directly related to the safe operation of the entire stringing system. Due to the inherent differences in wave impedance and damping characteristics between the front traction rope and the rear multi-split conductor, stress waves will be reflected and transmitted at the traction plate, which may trigger energy accumulation and oscillation chain reactions. At the same time, the non-streamlined shape of the traction plate will excite dynamic wake in motion, coupled with the non-synchronous oscillation of the sub-conductor, producing complex aerodynamic interference. These factors interact with each other, which may lead to the instability of the traction plate, the intensification of the sub-conductor vibration, and even cause equipment damage or safety accidents. The existing early warning methods are often based on static thresholds and cannot dynamically capture the evolution process of the risk as the traction plate moves. Moreover, they lack in-depth analysis of the coupling effects of multiple factors, leading to delayed or false alarms. This step solves the above problems by the following methods: First, based on the load evolution trajectory prediction information, the modal analysis method is used to analyze the interaction force intensity (such as high intensity interaction (such as 1000N)) of the dynamic wake modal information set and the multi-conductor non-synchronous oscillation information at each point on the evolution trajectory, to obtain potential interference modal information. Then, based on the potential interference modal information, combined with the energy accumulation instantaneous intensity (such as high intensity energy accumulation (such as 500J)), the feedback effect analysis method is used to analyze whether the energy accumulation under different forces presents positive feedback amplification effect or negative feedback suppression effect, to obtain interference phase risk information. Next, based on the interference phase risk information, combined with the energy accumulation sustained period information (such as long sustained period (such as 10 seconds)), the vibration criterion method is used to analyze whether the sustained positive feedback amplification effect will break through the dissipation limit of damping (such as low dissipation limit (such as 200J / s)), thereby triggering structural resonance, to obtain vibration potential evaluation information. After that, based on the vibration potential evaluation information, combined with the traction plate space configuration ratio information (such as high configuration ratio (such as 0.8)), the probability risk assessment method is used to analyze the chain reaction probability (such as high probability (such as 0.9)) between the common vibration potential and the dynamic instability of the traction plate, to generate dynamic risk field distribution information. Finally, based on the dynamic risk field distribution information, the risk matrix method is used to divide multiple levels of early warning grades (such as three levels of early warning) according to the risk field intensity from the diffusion risk (such as low risk area) to the concentrated outbreak risk (such as high risk area), to generate a hierarchical early warning strategy that integrates spatial positioning and evolution trend.

[0072] By the way provided by the embodiment, dynamic and fine evaluation of the risk level in the tension stringing process can be realized, potential dangerous points can be identified in time, and hierarchical early warning strategies can be generated according to the risk evolution trend, so as to effectively prevent the occurrence of traction plate instability and structural resonance, and improve the safety and reliability of the stringing process. At the same time, the hierarchical early warning strategy provides an accurate basis for adaptive regulation, avoids the problems of excessive early warning or insufficient early warning, optimizes resource allocation, and improves construction efficiency.

[0073] The system of the embodiment can be used to execute the method of any of the above embodiments, and has similar implementation principles and technical effects, which are not described here again.
