Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of intelligent monitoring and early warning of high and steep slope disasters, and in particular to an intelligent monitoring and early warning method and system for dangerous rockfall on high and steep slopes. Background Art
[0002] In the field of geological disaster prevention and control and mountain engineering safety assurance, monitoring the stability of high and steep slopes and providing early warnings for dangerous rockfalls are critical tasks. In recent years, with the rapid development of transportation, mining, hydropower projects, and other projects in mountainous areas, the number of large slopes formed by artificial excavation has increased rapidly. High and steep slopes have complex geological structures and are significantly affected by factors such as rainfall, weathering, and earthquakes. These slopes are prone to frequent potential collapses, slides, and rockfalls, posing a serious threat to human safety and the stability of infrastructure operations. Therefore, developing efficient and accurate intelligent monitoring and early warning systems for high and steep slopes has become a hot topic in current research and engineering applications.
[0003] Existing high-steep slope monitoring and early warning methods mostly rely on sensor deployment and manual threshold judgment strategies. By deploying a variety of monitoring instruments, such as crack meters, displacement meters, accelerometers, rain gauges, and microseismic monitoring equipment, they acquire data on changes in physical quantities on and within the slope surface. These methods typically employ sliding averages, trend comparisons, and single-indicator critical value alarms for risk assessment. Some systems incorporate fuzzy reasoning, expert knowledge bases, or logical rules to construct scoring models. While these systems can provide early warnings of abnormal slope changes to a certain extent, their reliance on static rules and low-dimensional analysis often makes it difficult to fully exploit the nonlinear correlations and evolutionary patterns among multi-source monitoring data. This results in limited early warning accuracy and a significant response lag.
[0004] In recent years, with the development of artificial intelligence, particularly deep learning, the capabilities of neural network models in time series prediction and state recognition have garnered widespread attention. Some studies have attempted to incorporate models such as long short-term memory (LSTM) networks and convolutional neural networks (CNN) into slope data analysis for trend prediction or anomaly identification. However, these approaches generally face the following challenges: First, the model structures lack specificity and fail to incorporate the temporal-spatial coupling characteristics of geological hazard scenarios; second, model parameter configuration relies on empirical settings, making it difficult to achieve personalized optimal configuration for specific engineering scenarios; and third, risk identification often relies on independent classification methods, failing to integrate them deeply with trend prediction, resulting in poor system connectivity and weak risk identification capabilities.
[0005] In terms of prediction methods, the currently commonly used models mostly use fixed sliding window inputs for single-point trend prediction, ignoring the spatial differences between sensors and the driving effect of inducing factors on state evolution. The prediction results are not accurate enough in the mutation stage. In terms of model optimization, traditional training strategies mostly rely on fixed hyperparameter settings and lack intelligent tuning of model structure and training configuration, making it difficult to achieve the generalization and adaptability of the model in different slope geological environments. In terms of risk scoring, existing methods often use a single indicator drive or linear weighted combination, ignoring the dynamic coupling relationship between various state variables and the fusion of future multi-time step information, making it difficult to accurately reflect the evolutionary risk of potential collapse or rockfall events.
[0006] In addition, the existing systems generally have the following deficiencies in their response mechanisms: the anomaly identification and trend prediction modules are deployed separately, lacking information sharing and feedback mechanisms, resulting in the inability of risk identification results to assist in the adaptive correction of the prediction model; the output results are often presented as single-variable curves or static warning levels, failing to build a closed-loop warning process of multivariable joint prediction-identification-scoring, making it difficult to achieve high-precision, real-time dynamic disaster risk assessment; at the same time, the model training process often lacks the special perception ability of high-risk points, and cannot strengthen model learning and resource allocation for sensitive areas, resulting in the risk of false alarms and missed alarms in local mutation environments.
[0007] Therefore, how to provide an intelligent monitoring and early warning method and system for dangerous rockfall on steep slopes is a problem that technical personnel in this field urgently need to solve. Summary of the Invention

[0112] Execute condor individual parameters The update operation formula represents the updating process of individual parameter vectors in the improved vulture search algorithm, comprehensively considering the influence of the current individual position, the global optimal solution, and the historical co-evolutionary direction. Its practical significance lies in achieving efficient search and dynamic adjustment of parameters in the long-term prediction network model. This formula controls the evolutionary behavior of individuals by introducing three key factors: the collaborative preference vector, which guides individuals along historically favorable directions, enhancing the stability and memory of the search; the global optimal parameter combination, which guides the population toward the current optimal solution and accelerates convergence; and the behavioral stage weight, which is dynamically adjusted based on the information entropy of the prediction residual to determine whether the current phase is exploration, trial, or convergence, thereby improving the algorithm's adaptability to different optimization stages. Through this combination of control variables, the algorithm maintains diversity while enhancing convergence, effectively avoiding local optima and ensuring that the search results for the optimal configuration of long-term prediction network structural parameters and training parameters are more accurate and robust in dynamic slope monitoring tasks, thereby improving the overall system's prediction performance and risk response capabilities.

[0117] in, is the predicted result, Y is the true value, is the subset of monitoring points with abnormal probability higher than the threshold, ‖θ‖2 is the L2 norm of the parameter vector, dim(θ) represents the number of parameter dimensions, represents the mean square error between the predicted value and the actual value, The variance of the subset of monitoring points whose anomaly probability is higher than the threshold;
[0118] The fitness function f(θ) formula is practically significant in that it constructs a multi-objective evaluation criterion to guide the optimization process toward a goal that simultaneously achieves high prediction accuracy, consistent anomaly responses, and low structural complexity. The first term in the formula is the mean squared error, which measures the deviation between the model's predicted values and the actual observed values, reflecting the model's basic predictive capability. The second term is the anomaly probability variance, which assesses the consistency of the model's response to anomalies at high-risk monitoring points. Large fluctuations in anomaly probability can lead to unstable warnings. The third term is the normalized L2 norm of the parameter, which controls model complexity to prevent overfitting and excessive resource consumption. Through the weighted combination of these three components, the fitness function achieves a comprehensive balance between prediction accuracy, risk identification stability, and model simplicity. It guides the vulture search algorithm to find the optimal parameter combination within the multi-objective optimization space, ensuring that the resulting prediction model is both engineering-ready and capable of accurately detecting the evolutionary trends and sudden anomalies of high-steep slope hazards.
[0119] S39, every set round T s Perform an individual migration operation between subpopulations. Based on the risk level and fitness score of each area, individuals with the best fitness are migrated from high-risk areas to low-risk areas, optimizing the population search diversity and global convergence ability.
[0120] S310, when the maximum number of iterations is reached or the fitness change for multiple rounds is lower than the set convergence threshold, the parameter combination θ with the minimum fitness function value is output g , as the final optimized parameter configuration of the long-term prediction network model.
[0121] By optimizing the structure of the vulture search algorithm, this paper proposes an improved mechanism for joint optimization of parameters in a long-term prediction network model, enhancing the model's adaptive tuning capabilities and search convergence efficiency in complex slope monitoring scenarios. By uniformly encoding structural and training parameters to construct an optimization vector, risk clustering is performed based on prediction results and anomaly probabilities, forming regional risk-associated subpopulations and implementing a differentiated optimization strategy. A co-evolutionary memory mechanism enhances the utilization of historical update trajectories, improving the continuity and stability of individual evolutionary directions. A behavioral gating function is introduced during the residual information entropy construction phase to achieve dynamic weight control for the circling search, tentative descent, and dive attack phases. The integration of a co-preference vector with the global optimal solution guides individual evolution, improving optimization directionality and convergence speed. Furthermore, by identifying high-risk points and modeling risk perception states, combined with a reinforcement learning agent module to adjust behavioral strategies, the search capability for local anomaly areas is enhanced. A multi-objective fitness function comprehensively evaluates individual performance based on prediction accuracy, anomaly consistency, and structural complexity. Global convergence is achieved through subpopulation migration and an optimal solution output mechanism. The overall optimization process improves the robustness, accuracy and adaptability of the prediction model, and effectively enhances the system's ability to model the complex dynamic evolution process of the slope.

[0129] By constructing a state prediction module with dynamic input guidance, dual-channel decoupled modeling, and joint anomaly identification capabilities, this invention significantly improves the modeling accuracy and response efficiency of long-term prediction network models for the complex state evolution of steep slopes. Dynamic guidance factors such as sensor activity, measurement point status, and previous cycle risk scores are introduced to construct a multi-source enhanced input structure, enabling the model to perceive changes in the monitoring environment in real time and enhancing the ability of input information to regulate prediction results. A structure in which trend prediction channels and displacement prediction channels operate in parallel, combined with a cross-trend attention mechanism, enables information sharing between trends and enhances associated features, improving the model's ability to express the dynamic coupling relationships of multivariate states. The anomaly risk classification branch jointly outputs anomaly probability values based on trend amplitude, feature distribution, and feedback information, addressing the issues of lagging and isolated anomaly detection in traditional methods. The final output results are structured and automatically indexed, improving the efficiency of system data interaction and result analysis. A consistency assessment mechanism dynamically determines the joint change pattern of crack and displacement prediction results and optimizes the model update strategy accordingly, achieving closed-loop control of prediction and feedback. Overall, this method has higher prediction accuracy, anomaly recognition sensitivity and system adaptability, significantly enhancing the intelligence and real-time level of disaster risk identification.
[0130] In this embodiment, the S5 specifically includes:
[0131] S51, receiving multi-step state prediction results output by the long-term prediction network model, including crack development trend, displacement change trend and abnormal response probability value;

[0137] This invention achieves quantitative assessment and intelligent grading of future state risks at monitoring points on steep slopes by constructing a multivariate-driven early warning risk scoring mechanism. By receiving crack development trends, displacement change trends, and abnormal response probability values output by a long-term prediction network model, the system comprehensively understands the evolutionary trends and potential abnormalities at monitoring points over the future time period. Prediction results are categorized and aggregated by monitoring point number to form a clearly structured multidimensional prediction information set. Missing or incomplete data is supplemented and marked to ensure the integrity and accuracy of the scoring data. Furthermore, the constructed early warning risk scoring input structure integrates key indicators such as crack values, displacement values, acceleration, rainfall, and microseismic amplitude. The scoring function dynamically combines the weights of different prediction indicators and their temporal characteristics to form a highly targeted risk measurement method. The scoring result for each monitoring point reflects its overall risk level over multiple future time steps and serves as the core basis for determining warning levels and disseminating information, forming a continuous and efficient risk conversion output mechanism. This method improves the sensitivity, accuracy, and automation of slope hazard early warnings, enables refined characterization of monitoring point-level risks and early warning responses, and provides reliable technical support for the prevention and control of major geological disasters.

[0146] Example 1:
[0147] In order to verify the feasibility of the present invention in implementation, the present invention was applied to the entrance and exit section of a certain mountain tunnel. To ensure road safety during the construction period and the subsequent traffic opening period, the local geological disaster monitoring department introduced the "intelligent monitoring and early warning system for dangerous rockfalls on steep slopes" proposed in the present invention, and conducted continuous monitoring and early warning pilot projects on a typical steep rock slope in the surrounding area.
[0148] The rock mass in this area is fractured, with slopes exceeding 70° and a height of approximately 95 meters. Rainfall is frequent year-round, and there are localized pockets of loose rock and developed joints. Historically, this has resulted in numerous small-scale rockfalls, posing a serious threat to the safety of the passages below. Traditional manual inspections are characterized by long inspection cycles, numerous blind spots, and delayed response to sudden disasters. There is an urgent need for a new intelligent, all-weather, and low-power monitoring and early warning system.
[0149] First, a drone equipped with an oblique camera captured high-precision terrain texture and point cloud data of the slope. Combined with ground-based laser scanning and total station measurements, the slope was modeled in 3D using CAD software. This data was then used for numerical simulation analysis using FLAC3D and Rockfall software to comprehensively assess slope stability and potential rockfall paths. The simulation identified five potential slip or collapse points. Based on the simulation results and the impact range of rockfall, ten sets of the rockfall monitoring devices described in this invention were deployed from the toe to the top of the slope.
[0150] Each device is equipped with a seismic wave detector, a high-definition wide-angle camera, a solar panel, a signal transmission module, and a rock-embedded barb fixing structure. It provides all-weather power supply and embedded stability, ensuring continuous operation in environments such as mountain disturbances, rain, fog, and high winds. The device also features combined image and seismic wave monitoring. Seismic signal monitoring is enabled by default, and the camera is automatically activated to capture images when abnormal amplitudes are detected.
[0151] All sensor data is uploaded in real time to a central signal receiving and processing system via an encrypted wireless protocol. The system is equipped with an intelligent analysis module based on deep learning and anomaly recognition. It uses a long-term prediction network model to fuse sensor data for trend analysis, and combines it with a vulture search algorithm to continuously optimize the model structure and training parameters. The model outputs crack trends, displacement trends, and abnormal response probabilities for each monitoring point over multiple future time steps, while quantifying the risk level using a predefined risk scoring function. This scoring function integrates multiple indicators, such as acceleration rate, microseismic amplitude, rainfall intensity, and crack evolution rate, to automatically calculate the risk score for each monitoring point and trigger a graded early warning mechanism.
[0152] At 17:32 on April 23, 2024, strong seismic wave signals (maximum acceleration of 0.36m / s) were continuously captured at the P4 monitoring point on the slope. 2 , microseismic amplitude reached 155μV), the system automatically triggered image acquisition, and the image recognition module identified the obvious displacement of rock blocks at the top of the slope and quickly located the abnormal area. The model prediction results showed that the crack growth trend at this point would exceed 1.6mm / h in the next hour, the abnormal probability value increased to 0.91, and the risk score reached 89.6 points (the high-risk threshold is 80 points). The system completed the processing within 30 seconds after the abnormality occurred and issued a three-level early warning instruction to engineering personnel, inspection vehicles, and management APP within a 5-kilometer range, successfully closing the channel. Subsequently, a local slope collapse actually occurred, but fortunately no casualties were caused.
[0153] The following are the prediction and response data of 8 typical monitoring points in the system operation during this test period, which verify the system's early identification and early warning response effects for high-risk conditions.
[0154] Table 1 Typical monitoring point prediction and risk response effect table
[0155]
[0156] As can be seen from the data in Table 1, the system combines the output results of the long-term prediction network model with the scoring function built based on multiple indicators to comprehensively evaluate the potential risks of each monitoring point in the future time period, and triggers early warning responses according to the risk score value.
[0157] Judging from the two monitoring indicators of acceleration and microseismic amplitude, the peak acceleration of monitoring point P4 reached 0.36m / s 2 The microseismic amplitude reached 155.2μV, the highest in the table. Combined with the crack development trend of 1.64mm / h and the abnormal probability value of 0.91, the system identified this area as a high-risk area, with a corresponding risk score of 89.6, triggering a Level 3 warning. In actual application, a local collapse event did occur at this location after the warning, demonstrating the system's high accuracy and proactiveness in identifying and responding to high-risk trends.
[0158] For example, P3 and P6 were also identified by the system as high-risk areas when the crack trend value exceeded 1.2 mm / h and the microseismic amplitude exceeded 130 μV, triggering level 2 and level 3 warnings, respectively. This demonstrates that the model not only responds to static structural changes but also has a strong ability to capture dynamic risks caused by external disturbances. While P1 and P8 had relatively moderate indicators, they still triggered level 1 and level 2 warnings due to their comprehensive scores exceeding 70 points, demonstrating that the system can maintain reasonable risk assessment sensitivity under boundary conditions.
[0159] It is worth noting that despite slight fluctuations in some individual indicators, P5 and P7 achieved comprehensive scores of 24.8 and 19.3, respectively, which did not reach the warning threshold, and the system did not falsely issue warnings. This demonstrates that the scoring mechanism is stable in avoiding false alarms and can effectively constrain over-responses in non-abnormal situations, demonstrating the superiority of the present invention in terms of model robustness and practical tolerance design.
[0160] Comprehensive analysis results show that this system, by integrating multi-source data (acceleration, microseismicity, cracks, rainfall, etc.), a multi-step prediction model, and an adaptive optimization algorithm, achieves precise slope disaster prediction, real-time response, and intelligent early warning. The system can not only identify high-risk locations in advance and output warning levels promptly, but also maintain high discrimination accuracy in non-risk areas. This effectively addresses the shortcomings of traditional methods in terms of weak disaster prediction capabilities, delayed response, and frequent false alarms, fully demonstrating the application advantages and engineering value of this invention in actual slope engineering scenarios.
[0161] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
