[0015] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0016] An embodiment of the present application provides a method for monitoring uneven settlement of the foundation of a cement electric pole tower.

[0017] Embodiment 1 Refer to Figure 1 As shown, it is a schematic flowchart of a method for monitoring uneven settlement of the foundation of a cement electric pole tower provided by an embodiment of the present invention. In this embodiment, the method for monitoring uneven settlement of the foundation of a cement electric pole tower includes: S1. Obtain the foundation bearing parameters and environmental geological data corresponding to the cement electric pole tower, construct a sensing displacement array adapted to the cement electric pole tower based on the foundation bearing parameters and the environmental geological data, deploy basic monitoring points for the cement electric pole tower based on the sensing displacement array, and perform reference calibration on the basic monitoring points to obtain an initial reference value.

[0018] By obtaining the foundation bearing parameters and environmental geological data corresponding to the cement electric pole tower, the present invention can construct an adapted sensing displacement array accordingly, realize accurate deployment of basic monitoring points and complete reference calibration, laying a solid foundation for subsequent monitoring work such as collecting displacement data and calculating settlement amounts.

[0019] Among them, the cement electric pole tower refers to a rod-shaped structure made of cement and used to support the transmission line in the power transmission system. This kind of pole tower has low cost, is firm and durable, and is a key infrastructure to ensure the stable power transmission. It is widely used in the construction of urban and rural power grids; the foundation bearing parameters refer to a series of data on the load-bearing capacity of the foundation of the cement electric pole tower, which cover the compressive strength of the foundation, that is, the maximum pressure that the foundation can bear, and the uplift force, that is, the ability to resist being pulled out of the ground. In addition, it also includes the bearing area of the foundation, which determines the size of the contact part between the foundation and the ground and affects the bearing effect; the environmental geological data refers to the data reflecting the geological and environmental conditions of the area where the electric pole tower is located, including the geological type, such as different geological compositions like rock, sand or clay; the groundwater level, whose change can cause the settlement or uplift of the foundation; the physical properties of the soil, such as the density, moisture content, acidity and alkalinity of the soil, these characteristics will affect the stability of the foundation, and at the same time, it also involves relevant information such as topography and landform. Optionally, the foundation bearing parameters corresponding to the cement electric pole tower can be directly measured by the dynamic penetration test; and the environmental geological data can be obtained through geological exploration techniques, such as: using drilling sampling (such as: core sampler) combined with ground penetrating radar (such as: GPR detector) to analyze environmental geological data such as soil layer structure and groundwater level.

[0020] Furthermore, based on the foundation bearing parameters and the environmental geological data, the present invention constructs a sensing displacement array adapted to the cement electric pole tower, which can ensure that the monitoring system accurately fits the actual working conditions of the cement electric pole tower. By deploying monitoring points according to the array, comprehensive and accurate displacement data can be obtained, the subtle changes in the settlement of the pole tower can be detected in time, and the sensitivity and reliability of the uneven settlement monitoring can be effectively improved.

[0021] Among them, the sensing displacement array refers to a monitoring array composed of multiple displacement sensors arranged and combined according to specific rules. These sensors are deployed at the key points of the foundation of the cement electric pole tower, aiming to collect displacement data of the pole tower under different working conditions in all directions and with high precision. During the construction process, it is necessary to refer to the foundation bearing parameters and environmental geological data of the electric pole tower to optimize the layout and ensure that the array can sensitively capture the settlement information of the foundation. Optionally, the construction of the sensing displacement array adapted to the cement electric pole tower can be realized through distributed optical fiber sensing technology, such as: using a Brillouin optical time domain reflectometer (such as: BOTDR) to lay optical fibers along the structure of the electric pole tower to monitor the strain distribution in real time, and finally obtain the sensing displacement array.

[0022] Furthermore, based on the sensing displacement array, the present invention deploys basic monitoring points for the cement electric pole tower, which can be accurately arranged at the key parts of the pole tower foundation where the force is applied, comprehensively capture the settlement displacement information, and at the same time, ensure that the layout of the monitoring points matches the characteristics of the pole tower and the environment where it is located, greatly improving the accuracy of the monitoring data.

[0023] Among them, the basic monitoring points refer to the points installed on the foundation of cement electric poles and towers, which are used to collect data such as displacement and settlement. These points use sensors to monitor the state of the poles and towers in real time. For example, in the urban power grid renovation project, basic monitoring points are set at the four corners and the center of the pole and tower foundation, and high-precision displacement sensors are used to collect the settlement data of the pole and tower foundation in real time.

[0024] As an embodiment of the present invention, deploying basic monitoring points for the cement electric pole and tower based on the sensing displacement array includes: analyzing the spatial distribution characteristics of the sensing displacement array; determining the key deformation area corresponding to the cement electric pole and tower based on the spatial distribution characteristics; dividing the high-sensitivity sub-areas in the key deformation area; querying the node layout rules corresponding to the high-sensitivity sub-areas; and deploying basic monitoring points for the cement electric pole and tower based on the node layout rules.

[0025] Among them, the spatial distribution characteristics refer to the spatial position relationship and arrangement rules of each sensor in the sensing displacement array. For example, in the monitoring of the cement electric pole and tower in a large substation, the sensing displacement array is distributed in a combination of a ring shape and a radial shape. The sensors are arranged in a ring along the edge of the pole and tower foundation and extend radially from the center to the edge. This spatial distribution characteristic determines the focus on displacement monitoring of different parts of the pole and tower. The key deformation area refers to the part of the cement electric pole and tower that is most likely to undergo significant deformation when subjected to force or environmental influence. Taking the electric pole and tower crossing a river as an example, due to the long-term impact of water flow and soil erosion on one side, the foundation near the river bank becomes the key deformation area. The high-sensitivity sub-area refers to a specific small area in the key deformation area that is more sensitive to settlement or deformation. In the foundation of the electric pole and tower in the coastal area, the key deformation area is greatly affected by tides and seawater erosion. Among them, the part close to the sea level and with a high sand content in the soil becomes the high-sensitivity sub-area. The node layout rules refer to the monitoring point arrangement specifications formulated according to the characteristics of the high-sensitivity sub-area. In the monitoring of the electric pole and tower in the mountainous area, for the high-sensitivity sub-area formed due to the risk of landslide, the node layout rules require monitoring points to be arranged at specific intervals in the uphill and downhill directions of this area to ensure comprehensive capture of potential displacement changes.

[0026] Further, the analysis of the spatial distribution characteristics of the sensing displacement array can be achieved through a spatial interpolation algorithm. For example, the Kriging interpolation method is used to reconstruct the spatial distribution of discrete displacement data to generate a continuous displacement field distribution map, and finally, spatial distribution characteristics such as displacement gradient and strain concentration area are obtained. The determination of the key deformation area corresponding to the cement electric pole tower can be achieved through an anomaly detection algorithm. For example, based on the Isolation Forest or Local Outlier Factor (LOF) algorithm, outliers in the displacement array are identified, and the high-stress concentration area is located by combining the calculation of strain energy density. Finally, the area where the deformation exceeds the safety threshold is obtained. The division of the highly sensitive sub-region in the key deformation area can be achieved through a clustering segmentation algorithm. For example, the DBSCAN density clustering is applied to group the measuring points in the key deformation area, and the highly active sub-region is divided by combining the displacement variance threshold (e.g., >3σ). Finally, the highly sensitive sub-region that needs to be monitored preferentially is obtained. The query of the node layout rule corresponding to the highly sensitive sub-region can be achieved through the invocation of a rule engine. For example, based on the Drools rule engine, the layout strategy is predefined (e.g., spacing ≤ 2m, three-way orthogonal measurement, etc.). Taking the geometric center of the highly sensitive sub-region as the key, the applicable sensor deployment rule is matched from the MongoDB document library. The deployment of the basic monitoring points for the cement electric pole tower can be achieved through the digital twin simulation method. For example, the BIM model is loaded in the Siemens Xcelerator platform, and the reliability of different point layout schemes is evaluated through Monte Carlo simulation. The combination of basic monitoring points with a displacement monitoring error < 1mm is selected.

[0027] By calibrating the basic monitoring points of the present invention to obtain the initial reference value, the subtle settlement changes of the foundation of the cement electric pole tower can be clearly detected, greatly improving the accuracy and reliability of the monitoring data. At the same time, the initial reference value can help quickly locate abnormal data and effectively reduce the false alarm rate.

[0028] Among them, the initial reference value refers to the value determined after calibrating the correction component set, which represents the reference value of the basic monitoring point under the standard state. For example, the initial displacement reference value of a certain basic monitoring point determined after calibration. All subsequent monitored displacement data will be compared with it to determine whether the foundation of the pole tower has settled or displaced.

[0029] As an embodiment of the present invention, the calibration of the basic monitoring points to obtain the initial reference value includes: collecting the multi-dimensional environmental parameters corresponding to the basic monitoring points; performing time-frequency joint analysis on the multi-dimensional environmental parameters to obtain time-frequency characteristic components; calculating the offset compensation coefficient corresponding to the time-frequency characteristic components; compensating and correcting the time-frequency characteristic components based on the offset compensation coefficient to obtain a correction component set; and calibrating the correction component set to obtain the initial reference value.

[0030] Among them, the multi-dimensional environmental parameters refer to multiple environmental dimension information that covers the factors affecting the measurement accuracy of the basic monitoring points. For example, in the monitoring scenario of field cement electric poles and towers, it includes meteorological parameters such as temperature, humidity, and atmospheric pressure. Because temperature changes will cause the thermal expansion and contraction of sensor elements, affecting the measurement accuracy; it also includes the intensity of the surrounding electromagnetic field, which is likely to interfere with the monitoring signal near high-voltage transmission lines. The time-frequency feature components refer to the feature components obtained by decomposing the multi-dimensional environmental parameters in the time and frequency dimensions through time-frequency joint analysis. Taking the temperature data collected over a period of time as an example, time-frequency joint analysis can separate the changing trend of temperature over time, such as the diurnal periodic change frequency, and the abnormal fluctuation components during certain specific periods. These decomposed components are the time-frequency feature components. The offset compensation coefficient refers to the calculation coefficient used to correct the offset of the time-frequency feature components caused by environmental factors. Taking the sensor measurement data affected by temperature as an example, through analysis, it is known that for every 1°C increase in temperature, the sensor measurement value will increase by a certain proportion. According to this relationship, the offset compensation coefficient for temperature change is calculated to correct the time-frequency feature components offset by temperature. The corrected component set refers to a set of data that accurately reflects the true environmental conditions obtained after compensating and correcting the time-frequency feature components using the offset compensation coefficient. For example, the signal components affected by electromagnetic field interference are adjusted according to the calculated offset compensation coefficient to remove the interference factors and form the corrected component set.

[0031] Furthermore, the acquisition of the multi-dimensional environmental parameters corresponding to the basic monitoring points can be achieved through multi-sensor fusion technology. For example, an Internet of Things terminal (such as: ESP32 + multi-parameter environmental sensor module) is used to synchronously collect data such as temperature and humidity (DHT22), wind speed (ultrasonic anemometer), and vibration (MEMS accelerometer), and transmit it to the cloud through LoRaWAN to finally obtain the multi-dimensional environmental parameters. The time-frequency joint analysis of the multi-dimensional environmental parameters can be achieved through time-frequency analysis algorithms such as short-time Fourier transform, wavelet transform, or Hilbert-Huang transform (HHT) to finally obtain the time-frequency feature components with time-domain and frequency-domain joint characterization. The calculation of the offset compensation coefficient corresponding to the time-frequency feature components can be achieved through regression analysis or optimization algorithms such as least squares method or gradient descent method to finally obtain the offset compensation coefficient for correcting measurement errors. The compensation and correction of the time-frequency feature components can be achieved through a linear compensation model such as a weighted correction matrix or Kalman filter based on the compensation coefficient to finally obtain the corrected component set that eliminates systematic errors. The reference calibration of the corrected component set can be achieved through statistical methods or machine learning such as the sliding window mean method or the isolated forest anomaly detection to finally obtain the initial reference value representing the environmental steady state.

[0032] S2. Based on the initial reference value, collect the displacement data of the cement electric pole tower within a fixed time period. According to the displacement data, calculate the uniform settlement amount corresponding to each point of the cement electric pole tower. Based on the uniform settlement amount and the corresponding tilt angle information of the cement electric pole tower, generate a deformation warning signal corresponding to the cement electric pole tower.

[0033] Based on the initial reference value, the present invention collects the displacement data of the cement electric pole tower within a fixed time period, greatly improving the effectiveness and availability of the data, laying a solid data foundation for subsequent generation of deformation warning signals and targeted tower maintenance work, and effectively ensuring the safe and stable operation of the power grid.

[0034] Among them, the fixed time period refers to the time interval for regularly collecting data preset according to the actual operation requirements of the cement electric pole tower and the characteristics of the surrounding environment. For example, in mountainous areas with unstable geological conditions, in order to timely grasp the settlement of the tower foundation, the fixed time period can be set to 1 week to collect data frequently to quickly detect potential risks; while in plain areas with stable geology, due to comprehensive considerations of operation and maintenance costs and efficiency, the fixed time period may be extended to 1 month. The displacement data refers to the relevant data reflecting the movement of the cement electric pole tower in space position, including horizontal displacement and vertical displacement. The horizontal displacement data can reflect whether the tower is tilted, such as the distance of the tower offset to one side under the action of strong wind; the vertical displacement data indicates whether the tower foundation is settled or lifted, such as the sinking or floating value of the tower foundation caused by the change of the groundwater level. Optionally, the collection of the displacement data of the cement electric pole tower within a fixed time period can be realized by high-precision displacement monitoring equipment, such as laser displacement sensors, GNSS dynamic monitoring systems and other equipment tools.

[0035] Furthermore, by calculating the uniform settlement amount corresponding to each point of the cement electric pole tower according to the displacement data, the present invention can predict the future settlement trend of the tower, formulate countermeasures in advance, greatly reduce the risks of tower tilt and collapse caused by settlement problems, ensure the stable power transmission, and reduce economic losses.

[0036] Among them, the uniform settlement amount refers to a quantitative value that comprehensively considers the displacement conditions of multiple monitoring points of the cement electric pole tower in different directions and reflects the overall settlement degree of the tower. It is a key index for measuring the settlement state of the tower foundation. The total monitoring duration refers to the time period from the moment when the displacement data starts to be collected (monitoring start time ), to the moment when the displacement data collection ends (monitoring end time ), and this entire time period can be represented by = − to represent.

[0037] As an embodiment of the present invention, calculating the uniform settlement amount corresponding to each point of the cement electric pole tower according to the displacement data includes: Calculating the uniform settlement amount corresponding to each point of the cement electric pole tower by using the following formula: ; Wherein, represents the uniform settlement amount corresponding to each point of the cement electric pole tower, represents the total monitoring duration corresponding to the monitored displacement data, represents the total number of monitoring points, represents the monitoring point index, and respectively represent the displacement amounts of the i-th monitoring point in the x / y directions, and respectively represent the weight coefficients of the displacements in the x / y directions, and respectively represent the start time and end time of monitoring, is the time decay coefficient, represents the environmental correction factor at time t.

[0038] Specifically, the displacement amount refers to the actual position movement distance of each monitoring point on the cement electric pole tower in the horizontal direction (divided into direction and direction) during the monitoring process. For example, under the influence of external factors (such as foundation changes, external forces, etc.), the offset distance generated by the monitoring point in the direction or direction is respectively represented by and ; the weight coefficient refers to the weight coefficients of the displacement in the direction and and , which are coefficients set artificially or obtained through calculation according to the actual situation (such as the tower structure characteristics, the influence degree of displacements in different directions on the tower stability, etc.), and are used to reflect the relative importance of the displacements in the , directions when calculating the uniform settlement amount. For example, if the tower is more susceptible to external factors and causes displacement in the direction, a larger weight can be given to ; the time decay coefficient refers to the characteristic that reflects the influence degree of displacement on the current uniform settlement amount calculation gradually decreases over time. In actual situations, the displacement that occurred earlier has a relatively smaller influence on the current tower settlement state, and the time decay coefficient is in exponential form , this time decay effect is reflected in the calculation; the environmental correction factor refers to the fact that environmental factors (such as temperature, humidity, wind force, etc.) will affect the displacement and settlement of the tower pole, It is used to correct the influence caused by environmental factors at different times when calculating the uniform settlement amount.

[0039] Based on the uniform settlement amount and the tilt angle information corresponding to the cement electric pole tower, the present invention generates a deformation warning signal corresponding to the cement electric pole tower, which can accurately capture the subtle deformation of the tower pole, predict potential risks in advance, and facilitate its rapid response, and take measures such as reinforcement and maintenance to ensure the safe and stable power transmission, and reduce the operation and maintenance costs and accident losses.

[0040] Among them, the tilt angle information refers to the angle data of the cement electric pole tower deviating from its vertical or ideal state, which is obtained through professional measurement equipment (such as an inclination sensor), covering the tilt angle values of the tower pole in different directions (such as horizontal and vertical). These data can intuitively reflect the tilt degree and direction of the tower pole. Combining with the uniform settlement amount, the deformation condition of the tower pole can be more comprehensively evaluated, which is an important basis for judging whether there are potential safety hazards in the tower pole and generating a deformation warning signal; the deformation warning signal refers to the signal generated based on the determined deformation critical point and used to warn that the cement electric pole tower may have dangerous deformation. It is presented in the form of sound, light, text message, system prompt, etc., reminding the operation and maintenance personnel that the tower pole is in a dangerous state and timely inspection, maintenance and other operations are required to avoid accidents.

[0041] As an embodiment of the present invention, generating the deformation warning signal corresponding to the cement electric pole tower based on the uniform settlement amount and the tilt angle information corresponding to the cement electric pole tower includes: analyzing the dynamic deviation coefficient between the uniform settlement amount and the preset settlement threshold; based on the dynamic deviation coefficient and the tilt angle information, comprehensively evaluating the cement electric pole tower to obtain a comprehensive evaluation index; extracting the abnormal index characteristics in the comprehensive evaluation index; based on the abnormal index characteristics, determining the deformation critical point corresponding to the cement electric pole tower; and generating the deformation warning signal corresponding to the cement electric pole tower based on the deformation critical point.

[0042] Among them, the dynamic deviation coefficient refers to the coefficient obtained by comparing and analyzing the uniform settlement amount with a preset settlement threshold, which reflects the degree of difference between the two. It measures the dynamic change of the current uniform settlement amount deviating from the safety standard (preset settlement threshold). The numerical value reflects the degree of deviation and is an important basic data for subsequent comprehensive evaluation. The comprehensive evaluation index refers to the quantitative index obtained by comprehensively considering the dynamic deviation coefficient and the inclination angle information through a specific evaluation method (such as weighted calculation, etc.), which is used to comprehensively measure the deformation state of the cement electric pole tower. This index integrates the two key factors of settlement and inclination and can more accurately reflect the overall deformation risk level of the pole tower. The abnormal index feature refers to the typical feature selected from the comprehensive evaluation index, indicating that the deformation state of the cement electric pole tower is abnormal. For example, the numerical value in the comprehensive evaluation index exceeds the normal fluctuation range, and the change trend shows a sharp rise, etc. These features are the key signals for judging whether there is a potential deformation danger in the pole tower. The deformation critical point refers to the critical state point determined according to the abnormal index feature, where the deformation of the cement electric pole tower reaches a state that can cause serious consequences such as structural damage and functional failure. When the deformation-related index of the pole tower approaches or reaches this point, it means that the safety risk increases significantly, and corresponding measures need to be taken immediately.

[0043] Further, the analysis of the dynamic deviation coefficient between the uniform settlement amount and the preset settlement threshold can be realized by a dynamic error analysis algorithm, such as: sliding window standard deviation calculation or adaptive Kalman filtering, and finally the dynamic deviation coefficient is obtained; the comprehensive evaluation of the cement electric pole tower can be realized by a multi-index fusion evaluation model, such as: analytic hierarchy process or fuzzy comprehensive evaluation method, and finally the comprehensive evaluation index covering dimensions such as displacement, inclination, and crack is obtained; the extraction of the abnormal index feature from the comprehensive evaluation index can be realized by an anomaly detection algorithm, such as: local outlier factor (LOF) or one-class support vector machine, and finally the abnormal index feature representing structural abnormality is obtained; the determination of the deformation critical point corresponding to the cement electric pole tower can be realized by a limit state analysis method, such as: based on a material strength degradation model or Monte Carlo simulation, and finally the deformation critical point with the structural failure probability exceeding the threshold is obtained; the generation of the deformation warning signal corresponding to the cement electric pole tower can be realized by a rule engine or a machine learning model, such as: Drools rule engine or LSTM time series prediction, and finally a graded (such as yellow / red) deformation warning signal is output.

[0044] S3. Based on the deformation warning signal, analyze the corresponding support weak area of the cement electric pole tower, determine the reinforcement priority corresponding to the support weak area, and according to the reinforcement priority, detect the stress distribution and crack propagation trend of the cement electric pole tower, and generate a settlement control instruction corresponding to the cement electric pole tower based on the stress distribution and the crack propagation trend.

[0045] Based on the deformation warning signal, the present invention analyzes the support weak areas corresponding to the cement electric pole towers, which helps the operation and maintenance personnel to formulate targeted reinforcement plans, reasonably allocate resources, efficiently improve the structural stability of the pole towers, prevent accidents such as overall collapse caused by local weakness, and ensure the safe operation of power facilities.

[0046] Among them, the support weak area refers to the area composed of stress concentration points and the affected areas around them. The support capacity of this area is relatively weak, and it is more likely to deform or even be damaged under the action of external loads or the environment. Once the support weak area is determined, it can provide a clear direction for subsequent reinforcement and maintenance work.

[0047] As an embodiment of the present invention, the analysis of the support weak areas corresponding to the cement electric pole towers based on the deformation warning signal includes: analyzing the deformation characteristic parameters in the deformation warning signal; dividing the deformation grade gradients corresponding to the deformation characteristic parameters; determining the deformation gradient areas corresponding to the deformation characteristic parameters based on the deformation grade gradients; locating the stress concentration points in the deformation gradient areas; and analyzing the support weak areas corresponding to the cement electric pole towers based on the stress concentration points.

[0048] Among them, the deformation characteristic parameters refer to the data indicators used to describe the deformation state of the cement electric pole tower in the deformation warning signal, such as the inclination angle, the uniform settlement amount, and their change rates, etc. Taking the inclination angle as an example, its magnitude and the increase or decrease amplitude in different time periods all belong to the deformation characteristic parameters; the deformation grade gradient refers to the ordered gradient system formed by quantitatively grading the deformation characteristic parameters according to industry standards and actual operation experience. For example, the uniform settlement amount is divided into three grades: mild, moderate, and severe, and each grade corresponds to a clear settlement amount interval; the deformation gradient area refers to the physical area of the pole tower corresponding to each grade after determining the deformation grade gradient. Due to the differences in force and environmental impacts in different areas, different degrees of deformation will occur. For example, a certain section of the pole tower is close to the river and is affected by water flow scouring, so the settlement grade is relatively high, and this area constitutes a specific deformation gradient area; the stress concentration point refers to the point in the deformation gradient area where the stress is significantly higher than the surrounding area due to factors such as sudden changes in structural shape and uneven force. At the connection of the pole tower, due to the large bending moment and shear force it bears, it is easy to become a stress concentration point, which is a weak link in the structural stability.

[0049] Furthermore, the deformation characteristic parameters in the analyzed deformation warning signal can be realized by signal feature extraction algorithms, such as: Fast Fourier Transform (FFT) or wavelet packet decomposition, and finally, deformation characteristic parameters including displacement amplitude, frequency components, and phase difference are obtained; the division of the deformation level gradient corresponding to the deformation characteristic parameters can be realized by clustering analysis methods, such as: K-means clustering or Gaussian Mixture Model (GMM), and finally, the deformation level gradient divided based on the severity of deformation is obtained; the determination of the deformation gradient region corresponding to the deformation characteristic parameters can be realized by spatial interpolation algorithms, such as: Kriging interpolation or inverse distance weighting method, and finally, the deformation gradient region reflecting the deformation distribution characteristics is obtained; the positioning of the stress concentration points in the deformation gradient region can be realized by finite element analysis methods, such as: stress nephogram analysis using finite element software such as ANSYS or ABAQUS, and finally, the stress concentration points where the maximum principal stress exceeds the threshold are obtained; the analysis of the support weak areas corresponding to the cement electric pole towers can be realized by structural reliability assessment methods, such as: weak link identification based on sensitivity analysis or neural network prediction model, and finally, the support weak areas with insufficient bearing capacity are obtained.

[0050] By determining the reinforcement priority corresponding to the support weak areas, the present invention can effectively reduce the occurrence probability of major accidents such as pole tower collapse, save huge maintenance costs and power outage losses caused by accidents, and ensure the continuous and stable operation of the power system.

[0051] Among them, the reinforcement priority refers to a quantitative index for ranking the urgency of reinforcement according to the risk degree of the support weak areas of the cement electric pole tower. For example, if a support weak area not only has serious stress concentration but also rapid deformation growth, and once damaged, it can cause the overall collapse of the pole tower, such areas will be given a higher reinforcement priority. Optionally, the determination of the reinforcement priority corresponding to the support weak areas can be realized by multi-criteria decision analysis methods, such as: using TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) or the combined evaluation model of AHP-entropy weight method, comprehensively considering factors such as structural damage degree, stress concentration coefficient, and failure consequences, and finally obtaining the quantitative reinforcement priority.

[0052] Furthermore, according to the reinforcement priority, the present invention detects the stress distribution and crack propagation trend of the cement electric pole tower, can deeply understand the structural health status of the pole tower, provides a reliable basis for formulating a scientific and reasonable reinforcement plan, effectively prevents the further expansion of cracks, prevents the pole tower from collapsing due to stress concentration, and ensures the stable operation of the power system.

[0053] Among them, the stress distribution refers to the magnitude and direction distribution of the stresses borne by different positions inside the cement electric pole tower. During the actual operation of the tower, due to the combined action of various loads such as its own gravity, conductor tension, and wind force, the stress distribution at each point inside is not uniform. For example, at the root of the tower, because it has to bear the weight of the entire tower and the line, the stress is relatively large; at the corner of the tower, due to the complex stress conditions, the stress distribution is also different from other parts. The crack propagation trend refers to the development trend of the cracks on the surface or inside of the cement electric pole tower in terms of length, width, depth, etc. over time. For example, for cracks caused by concrete carbonation and steel bar corrosion, their propagation direction will follow the direction of the steel bars, and the propagation speed will also change due to environmental factors such as humidity and temperature. Optionally, to detect the stress distribution of the cement electric pole tower, digital image correlation technology (DIC) combined with fiber Bragg grating sensors (FBG) can be used. Through non-contact strain measurement and distributed stress monitoring, a high-precision three-dimensional stress distribution cloud map can be finally obtained. The crack propagation trend can be obtained by using acoustic emission detection technology (AE) in cooperation with computer vision algorithms (such as the YOLOv5 crack recognition model). By real-time collecting crack acoustic emission signals and image features, the quantitative trend data of crack length, width, and propagation rate can be finally obtained.

[0054] Based on the stress distribution and the crack propagation trend, the present invention generates a settlement control instruction corresponding to the cement electric pole tower, which can timely initiate settlement control measures, prevent structural damage caused by settlement, avoid line faults and safety accidents, reduce the operation and maintenance costs of the power system, and ensure the stable and reliable power supply.

[0055] Among them, the settlement control instruction refers to the command information generated according to the settlement pressurization sequence and used to guide the actual operation equipment to execute the settlement control task. These instructions can be transmitted to the automatic control system to drive the corresponding mechanical equipment to perform operations such as pressurization and unloading on the cement electric pole tower.

[0056] As an embodiment of the present invention, generating the settlement control instruction corresponding to the cement electric pole tower based on the stress distribution and the crack propagation trend includes: extracting the stress peak points in the stress distribution; determining the stress control direction corresponding to the cement electric pole tower based on the stress peak points; setting the gradient pressurization threshold corresponding to the cement electric pole tower based on the stress control direction and the crack propagation trend; constructing the settlement pressurization sequence corresponding to the cement electric pole tower based on the gradient pressurization threshold; and generating the settlement control instruction corresponding to the cement electric pole tower based on the settlement pressurization sequence.

[0057] Among them, the stress peak points refer to specific position points in the stress distribution data of the cement electric pole tower where the stress values reach relatively the highest. Due to bearing excessive stress, these points become the weak links of the structure and are most likely to cause material failure or structural deformation. For example, at the connection between the root of the electric pole tower and the foundation, since it has to bear the weight of the entire pole tower and various external applied forces, stress peak points are often easily formed; the stress regulation direction refers to the operation direction determined based on the position and stress conditions of the stress peak points to adjust the stress distribution and reduce the stress peak. When the stress peak points are concentrated on one side of the pole tower, the stress regulation direction can be to reinforce the other side or adjust the load distribution, so as to balance the overall stress of the pole tower, relieve the stress concentration phenomenon, and maintain the structural stability; the gradient pressure threshold refers to a series of phased upper pressure limit values set by comprehensively considering the stress regulation direction and the crack propagation trend. For example, in the stage where the crack propagation is relatively slow, a relatively high pressure threshold can be set to accelerate the settlement regulation process; while when the crack propagates rapidly, the pressure threshold is reduced and the regulation is carried out carefully; the settlement pressure sequence refers to an ordered operation step containing information such as the pressure application time, pressure magnitude, and action time constructed based on the gradient pressure threshold. By applying pressure in a planned manner, the settlement of the pole tower is gradually adjusted to effectively control its stress distribution and crack propagation. For example, at pre-set time intervals, the specific parts of the pole tower are pressurized in sequence with different pressure values.

[0058] Furthermore, the extraction of the stress peak points in the stress distribution can be achieved through image processing algorithms, such as: local extreme value detection algorithms based on OpenCV or three-dimensional point cloud peak extraction techniques, and finally stress peak points with stress concentration exceeding the threshold are obtained; the determination of the stress regulation direction corresponding to the cement electric pole tower can be achieved through finite element inverse optimization algorithms, such as: using the ANSYS topology optimization module or genetic algorithm (GA) for stress path analysis, and finally a vector set of the optimal stress dispersion direction is obtained; the setting of the gradient pressure threshold corresponding to the cement electric pole tower can be achieved through a material mechanics model, such as: a segmented pressure threshold model established based on the concrete compressive strength curve and Weibull distribution, and finally a multi-level pressure threshold matching the structural bearing capacity is obtained; the construction of the settlement pressure sequence corresponding to the cement electric pole tower can be achieved through a timing planning algorithm, such as: using dynamic programming or reinforcement learning methods to optimize the pressure application time and intensity, and finally a progressive pressure application step sequence taking into account both efficiency and safety is obtained; the generation of the settlement regulation instruction corresponding to the cement electric pole tower can be achieved through an industrial control system, such as: using PLC programming logic or PID control algorithms to convert the pressure application parameters, and finally an executable control instruction set for the pressure grouting equipment is output.

[0059] S4. Analyze the feedback data corresponding to the settlement control instruction, identify the abnormal settlement patterns in the feedback data, and calculate the instability risk coefficient corresponding to the cement electric pole tower based on the abnormal settlement patterns.

[0060] By analyzing the feedback data corresponding to the settlement control instruction and identifying the abnormal settlement patterns in the feedback data, the present invention helps to reverse-analyze the problems in the settlement control process, optimize the subsequent control strategies, reduce the operation and maintenance costs, and continuously ensure the stable operation of the power system.

[0061] Among them, the feedback data refers to the data collected by various sensors after the settlement control instruction is executed, which is used to reflect the change of the settlement state of the cement electric pole tower. These data cover information such as the real-time settlement amount of the pole tower, the change of stress distribution, and the change of inclination angle. For example, the displacement sensor installed at the pole tower foundation will record the settlement distance of the pole tower in real time; the stress sensor will feedback the change of the stress magnitude of each part of the pole tower during the control process; the abnormal settlement pattern refers to the settlement change rule that is contrary to the normal settlement performance and implies the structural safety risk of the cement electric pole tower. Common abnormal settlement patterns include that the settlement rate suddenly accelerates, far exceeding the normal control expectation; the settlement direction deviates, deviating from the original control direction; or there are periodic abnormal fluctuations, etc. Taking the sudden acceleration of the settlement rate as an example, under normal circumstances, under the action of the settlement control instruction, the settlement of the pole tower should be in a slow and stable state. If the settlement rate rises sharply in a short period of time, it is very likely that the foundation structure of the pole tower is damaged and needs to be immediately investigated and processed. Optionally, the analysis of the feedback data corresponding to the settlement control instruction can be achieved by time series analysis methods, such as using the ARIMA model or the LSTM neural network to perform trend fitting and residual analysis on the feedback data such as the settlement rate and pressure value, and finally obtaining a feedback data set including the control effect evaluation index; the identification of the abnormal settlement pattern in the feedback data can be achieved by pattern recognition technology, such as using the dynamic time warping (DTW) algorithm or wavelet transform modulus maximum detection, and finally locating the abnormal settlement pattern with characteristics such as mutation and oscillation by comparing with the standard settlement pattern library.

[0062] Furthermore, based on the abnormal settlement pattern, the present invention calculates the instability risk coefficient corresponding to the cement electric pole tower, which not only effectively avoids the waste of resources caused by misjudgment, but also significantly improves the efficiency of dealing with emergencies, takes preventive measures in advance, and minimizes the safety accident risk caused by the instability of the pole tower.

[0063] Among them, the instability risk coefficient is a quantitative value that comprehensively considers the change of the abnormal settlement pattern within a specific time period, the dispersion degree of the data sample, as well as environmental factors and other comprehensive factors, and is used to evaluate the likelihood of the cement electric pole tower being unstable due to abnormal settlement. The higher the value, the greater the instability risk of the pole tower.

[0064] As an embodiment of the present invention, calculating the instability risk coefficient corresponding to the cement electric pole tower based on the abnormal settlement pattern includes: Calculating the instability risk coefficient corresponding to the cement electric pole tower by using the following formula: ; Wherein, represents the instability risk coefficient corresponding to the cement electric pole tower, and respectively represent the start time and end time of the settlement time period corresponding to the abnormal settlement pattern, represents the change rate corresponding to the abnormal settlement pattern at time t, represents the total number of data samples corresponding to the abnormal settlement pattern, represents the quantity index corresponding to the data sample, represents the th sample actual value corresponding to the data sample, represents the sample average value of the data sample, represents the environmental stability coefficient related to the abnormal settlement pattern, represents the comprehensive influence factor.

[0065] Specifically, the settlement time period refers to the time period from the start time when the abnormal settlement pattern of the cement electric pole tower is monitored , to the monitoring cut-off time of the abnormal settlement pattern. By defining this time period, the analysis can focus on the abnormal settlement situation of the pole tower within a specific duration; the change rate refers to the rate of change of the characteristics related to the abnormal settlement pattern (such as settlement amount, settlement speed, etc.) with time at each time moment. For example, if the settlement amount increases rapidly within a unit time, then the corresponding value will be larger, which reflects the dynamic change characteristics of the abnormal settlement pattern; the data sample refers to a series of relevant data collected when analyzing the abnormal settlement pattern of the cement electric pole tower. These data can include settlement amounts, settlement speeds, inclination angles, etc. at different time points. By collecting multiple data samples, the characteristics of the abnormal settlement pattern can be described more comprehensively; the sample actual value refers to the actual measured value corresponding to each specific data sample. For example, in a certain monitoring, the settlement amount value measured at the th time point is the sample actual value of the data sample; the sample average value refers to the sum of the actual values of all data samples divided by the total number The obtained value represents the average level of these data samples and is used to compare with the actual value of each sample to measure the deviation degree of the actual value of the sample. The environmental stability coefficient refers to a coefficient obtained after comprehensively considering the influence of external environmental factors (such as geological conditions, climate conditions, etc.) where the cement electric pole tower is located on its settlement stability. If the pole tower is in an environment with stable geology and mild climate, the S value is relatively large, indicating that the adverse impact of the environment on settlement is small. On the contrary, in an environment with unstable geology or harsh climate, the S value is small. The comprehensive influence factor refers to a coefficient obtained after comprehensively considering other factors (such as the structural characteristics of the pole tower itself, the external force situation, etc.) that affect the instability of the cement electric pole tower due to abnormal settlement in addition to environmental factors.

[0066] S5. Based on the instability risk coefficient, compensate and correct the offset data of the cement electric pole tower to obtain compensated and corrected data, analyze the settlement evolution law corresponding to the compensated and corrected data, and formulate a hierarchical maintenance strategy corresponding to the cement electric pole tower based on the settlement evolution law.

[0067] Based on the instability risk coefficient, the present invention compensates and corrects the offset data of the cement electric pole tower to obtain compensated and corrected data, which helps to more accurately evaluate the state of the pole tower, enables the operation and maintenance personnel to timely grasp the real situation, reasonably formulate maintenance strategies, effectively reduces the risk of decision-making errors caused by data errors, and ensures the safe and stable operation of the pole tower.

[0068] Among them, the compensated and corrected data refers to the data obtained by adjusting the original offset data of the cement electric pole tower using a compensation and correction factor. These data remove or reduce the interference of abnormal fluctuations such as high-frequency oscillations and can more accurately reflect the actual and stable offset state of the pole tower.

[0069] As an embodiment of the present invention, compensating and correcting the offset data of the cement electric pole tower based on the instability risk coefficient to obtain compensated and corrected data includes: extracting the dynamic fluctuation component in the instability risk coefficient; fitting the offset trend curve corresponding to the cement electric pole tower based on the dynamic fluctuation component; identifying the high-frequency oscillation interval in the offset trend curve; inversely deducing the compensation and correction factor corresponding to the offset data based on the high-frequency oscillation interval; and compensating and correcting the offset data of the cement electric pole tower based on the compensation and correction factor to obtain compensated and corrected data.

[0070] Among them, the dynamic fluctuation component refers to the part of the instability risk coefficient that reflects its fluctuation with time or other factors, which reflects the dynamic changes of the instability risk in different stages. For example, affected by environmental factors, load changes, etc., the amount of fluctuation in the instability risk coefficient is the basic data feature for subsequent analysis; the offset trend curve refers to a curve obtained by mathematical fitting based on the dynamic fluctuation component, which is used to describe the change trend of the offset of the cement electric pole tower with time or other variables. This curve can intuitively show whether the pole tower offset is rising, falling or stable, and helps to analyze the overall trend and law of the offset; the high-frequency oscillation interval refers to the time period or area where the offset data fluctuates frequently and rapidly on the offset trend curve. This high-frequency oscillation means that the offset state of the pole tower is unstable and there are potential abnormal factors affecting it, such as sudden changes in external loads, local changes in the foundation, etc.; the compensation correction factor refers to a value obtained by inverse deduction through a specific algorithm according to the characteristics of the high-frequency oscillation interval (such as oscillation amplitude, frequency, etc.), which is used to adjust the original offset data. It measures the degree and direction of the correction required for the offset data to eliminate the influence of abnormal factors such as high-frequency oscillation.

[0071] Furthermore, the extraction of the dynamic fluctuation component in the instability risk coefficient can be achieved through time-frequency decomposition algorithms. For example, empirical mode decomposition or variational mode decomposition is used to perform multi-scale decomposition on the IR coefficient time series, and finally the dynamic fluctuation component representing short-term risk fluctuations is obtained; the fitting of the offset trend curve corresponding to the cement electric pole tower can be achieved through non-linear regression methods. For example, Gaussian process regression or cubic spline interpolation algorithm is used to construct a trend surface equation in combination with historical offset data, and finally a continuously differentiable offset trend function curve is obtained; the identification of the high-frequency oscillation interval in the offset trend curve can be achieved through wavelet transform. For example, through the detection of the modulus maximum value of the Morlet wavelet coefficient, the oscillation interval with an energy density exceeding the 3σ threshold is located in the time-frequency joint domain; the inverse deduction of the compensation correction factor corresponding to the offset data can be achieved through inverse modeling techniques. For example, the parameter inversion method based on Tikhonov regularization is used to minimize the residual between the observed data and the model output, and finally a compensation factor matrix including stiffness correction terms and damping correction terms is obtained; the compensation correction of the offset data of the cement electric pole tower can be achieved through the state space correction method. For example, an extended Kalman filter model including compensation factors is established, and through the iterative process of state prediction - measurement update, finally a compensation correction data set eliminating system errors is output.

[0072] By analyzing the settlement evolution law corresponding to the compensation correction data, the present invention helps to reasonably plan maintenance and repair work, optimize resource allocation, avoid pole tower damage caused by settlement problems, ensure the stability and safety of power transmission, and reduce operation and maintenance costs and accident risks.

[0073] Among them, the settlement evolution law refers to the regular characteristics presented by the settlement state of the cement electric pole tower during operation as it changes with time, environmental factors (such as temperature changes, precipitation effects, geological changes, etc.) and its own stress conditions (such as load increase or decrease, structural changes, etc.), including the increasing or decreasing trend of the settlement amount, whether it is uniform, accelerating or decelerating settlement; the fluctuation of the settlement speed; whether the settlement direction changes; and the periodic or stage characteristics of the settlement under different external conditions or its own states. These laws can reflect the internal mechanism and development trend of the pole tower settlement. Optionally, the analysis of the settlement evolution law corresponding to the compensation and correction data can be achieved through time series analysis methods, such as: ARIMA model, LSTM neural network method, combined with historical data to model and predict the settlement evolution law.

[0074] Furthermore, based on the settlement evolution law, the present invention formulates a hierarchical maintenance strategy for the cement electric pole tower, which can carry out differentiated operations for different grades of pole towers, prioritize the treatment of high-risk pole towers, avoid resource dispersion, can timely eliminate hidden dangers, reduce the probability of accidents such as pole tower collapse, and can also reduce unnecessary maintenance costs, ensuring the stability and reliability of power supply.

[0075] Among them, the hierarchical maintenance strategy refers to a management method that divides the cement electric pole tower into different grades according to its settlement evolution law and risk level, and formulates corresponding maintenance measures for different grades. Usually, it is graded according to indicators such as settlement amount, settlement speed, and stability of the settlement trend. For example, a pole tower with a small settlement amount and a stable trend is classified as a low-risk grade, and measures such as regular inspection and simple maintenance are taken; while a pole tower with a large settlement amount, a fast speed or an unstable trend is listed as a high-risk grade, which requires increasing the inspection frequency, conducting detailed structural inspections, and timely taking measures such as reinforcement or repair. Optionally, the formulation of the hierarchical maintenance strategy corresponding to the cement electric pole tower can be achieved through strategy formulation tools, such as: Power BI, Tableau and other tools.

[0076] Compared with the problems described in the background art, the present invention can construct an adapted sensing displacement array by obtaining the basic bearing parameters and environmental geological data corresponding to the cement electric pole tower, so as to accurately deploy the basic monitoring points and complete the reference calibration, laying a solid foundation for subsequent monitoring work such as collecting displacement data and calculating the settlement amount. Based on the initial reference value, the present invention collects the displacement data of the cement electric pole tower within a fixed time period, greatly improving the effectiveness and availability of the data, laying a data foundation for subsequent generating deformation warning signals and carrying out targeted pole tower maintenance work, and effectively ensuring the safe and stable operation of the power grid. Further, based on the deformation warning signal, the present invention analyzes the support weak area corresponding to the cement electric pole tower, which helps the operation and maintenance personnel to formulate a targeted reinforcement plan, reasonably allocate resources, and efficiently improve the structural stability of the pole tower, preventing accidents such as overall collapse caused by local weakness and ensuring the safe operation of power facilities. Further, by analyzing the feedback data corresponding to the settlement control instruction and identifying the abnormal settlement mode in the feedback data, the present invention helps to reverse-analyze the problems in the settlement control process, optimize the subsequent control strategy, reduce the operation and maintenance cost, and continuously ensure the stable operation of the power system. Finally, based on the instability risk coefficient, the present invention compensates and corrects the offset data of the cement electric pole tower to obtain the compensated and corrected data, which helps to more accurately evaluate the state of the pole tower, enables the operation and maintenance personnel to timely master the real situation, reasonably formulate the maintenance strategy, and effectively reduce the risk of decision-making errors caused by data errors, ensuring the safe and stable operation of the pole tower. Therefore, a method and system for monitoring uneven settlement of the foundation of a cement electric pole tower provided by the embodiments of the present invention can improve the safety and stability of the structure maintenance of the cement electric pole tower.
