TECHNICAL FIELD
[0001] The present application relates to the technical field of intelligent information processing, and in particular to a multi-modal data driven potential disaster intelligent perception and emergency data engineering system. BACKGROUND
[0002] In recent years, with the development of sensing technology, communication technology and high-performance computing, the real-time monitoring and emergency response capability for natural disasters has been significantly improved. The emergence of multi-modal heterogeneous data acquisition and fusion technology enables the integration of multi-source data from satellite remote sensing, ground sensor networks, unmanned aerial vehicle platforms and weather radars under the same spatio-temporal reference, thereby providing a richer information base for disaster prediction and risk assessment. At the same time, geomechanical modeling and high-performance numerical solving methods are constantly improving, making it possible to simulate disaster evolution based on physical mechanisms; emerging metasurface communication and beamforming technology provides a new means for high-reliability, low-power data transmission in complex terrain and harsh environments.

For example, in disaster simulation calculation, the dynamic adaptation ability of physical modeling and numerical solving to energy consumption is insufficient, which may lead to a decrease in calculation efficiency in energy-limited environments; in terms of communication, although beamforming technology can optimize link quality, parameter adjustment often fails to comprehensively optimize in combination with disaster risk spatial distribution and energy state.

[0051] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0052] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application, however, can be practiced in a variety of ways beyond the specific embodiments described herein without departing from the scope of the present application, and it is understood that variations can be made in view of what is described herein, by individuals skilled in the art, without departing from the spirit and scope of the present application.
[0053] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is separate or alternative to other embodiments.
[0054] Reference Figs. 1-4 For one embodiment of the present application, the embodiment provides a multi-modal data-driven potential disaster intelligent perception and emergency data engineering system, comprising the following steps:
[0055] The data processing module collects multi-modal heterogeneous data and performs spatio-temporal alignment processing to generate a standardized spatio-temporal matrix.
[0056] The dynamic time warping algorithm is used to synchronize the time of the multi-modal heterogeneous data, output a time-aligned data sequence, and convert the time-aligned data sequence into spatial coordinates in combination with the RTK positioning information to generate spatio-temporal aligned data.
[0057] Specifically, the multi-modal heterogeneous data includes meteorological sensor measurement data, hydrological sensor measurement data, geological sensor measurement data, and satellite remote sensing data.
[0058] The dynamic time warping algorithm is used to compare the collected multi-modal heterogeneous data in sequence according to the time stamp, perform nonlinear stretching or compression on the time series of different data sources, align the features corresponding to each time point, and output a time-aligned data sequence.
[0059] The time-aligned data sequence is matched with the longitude, latitude and elevation coordinates in the RTK positioning information, the data at each time step is mapped to the corresponding spatial coordinates to form spatio-temporal aligned data, which contains time information and spatial coordinate information, for example, the temperature, humidity and vibration data collected by different sensors in the same second are respectively mapped to the same geographic location coordinates to realize unified representation of time and space.
[0060] The spatio-temporal aligned data is subjected to format standardization processing to form a standardized spatio-temporal matrix.
[0061] Specifically, the spatio-temporal alignment data is standardized, including unit unification, value normalization and missing value filling of the feature data of each time step, arranging different data types of features in column order, and generating a unified data table structure.
[0062] The time information, spatial coordinates and various feature values are organized into a matrix form, with the rows of the matrix corresponding to the time steps and the columns corresponding to the spatial positions and feature channels. For example, temperature, humidity, vibration and displacement data are arranged in a fixed order into the matrix columns to form a standardized spatio-temporal matrix.
[0063] The energy management module monitors the energy state in real time according to the standardized spatio-temporal matrix, selects a calculation mode and drives the physical neural operator accelerator to output energy control instructions.
[0064] According to the time and position synchronization information of the standardized spatio-temporal matrix, the output power and supercapacitor capacity are collected in real time by the energy monitoring sensor and preprocessed to form energy state parameters.
[0065] Specifically, according to the time and position synchronization information of the standardized spatio-temporal matrix, the output power and supercapacitor capacity are collected in real time by the energy monitoring sensor, and the collected voltage, current and capacity signals are subjected to noise filtering and signal smoothing processing, such as moving average method or weighted filtering method for processing of continuous sampling data. The power and capacity at each time are normalized according to the sampling time, the units and value ranges are unified, the processed power values and capacity values are arranged according to the time steps and spatial positions, and the energy state parameters including the output power and supercapacitor capacity of each time step are formed.
[0066] According to the energy state parameters, the current energy sufficiency and task calculation demand are determined, the matching calculation mode is determined by the mode selection logic, and the selected calculation mode is encoded into a calculation mode signal.
[0067] Specifically, the energy state parameters of each time step are compared with the preset output power threshold and supercapacitor capacity threshold to determine whether the current energy meets the load and energy storage requirements, thereby generating an energy sufficiency classification result.
[0068] According to the task calculation demand, the calculation task type and the corresponding calculation load are matched, for example, high-load tasks are matched with high energy state, and low-load tasks are matched with medium-low energy state, and the matching calculation mode of each time step is determined by the mode selection logic. The selected calculation mode is converted into a calculation mode signal according to a preset encoding rule, such as binary or multi-bit encoding method, and a calculation mode signal sequence corresponding to each time step is output.
[0069] It should also be noted that the specific steps of the output power threshold and the super capacitor power threshold: according to the task calculation demand and the energy supply capacity, the output power thresholds corresponding to the high, medium and low energy states are preset, for example, the high energy state threshold is 80%, and the low energy state threshold is 20%; At the same time, according to the super capacitor charging and discharging characteristics and the continuous energy supply time requirement, the super capacitor power thresholds corresponding to the high, medium and low energy states are preset, for example, the high energy state threshold is 80%, and the low energy state threshold is 20%; In each time step, the real-time collected output power and super capacitor power are compared with the preset super capacitor power threshold, and it is judged whether the current energy state belongs to high, medium or low energy state, so as to provide basis for subsequent calculation mode selection.
[0070] The preset encoding rule establishes a mapping relationship between each calculation mode and the corresponding encoding value according to the calculation mode classification in the standardized space-time matrix and the task calculation demand; The encoding value can be expressed in binary or decimal, for example, the high-performance calculation mode is encoded as "11", the energy-saving mode is encoded as "01", and the ordinary calculation mode is encoded as "10"; The encoding rule is derived from the analysis of the functional characteristics of the calculation mode and the energy management strategy, so as to ensure that the encoding can uniquely identify each calculation mode and adapt to the energy control instruction transmission and analysis requirements.
[0071] The calculation mode signal is converted into corresponding energy control instruction, and sent to the physical neural operator accelerator to drive operation, and the energy control instruction is output.
[0072] Specifically, the calculation mode signal is analyzed according to the preset encoding rule, and is mapped into the parameter value corresponding to the energy control instruction, for example, the encoding "11" is converted into the high-performance calculation mode instruction, and the encoding "01" is converted into the energy-saving mode instruction; The mapped energy control instruction is sent to the physical neural operator accelerator through the control interface of the physical neural operator accelerator to drive operation, and the physical neural operator accelerator adjusts the calculation resource allocation and energy use strategy according to the received energy control instruction, completes the operation control, and outputs the energy control instruction.
[0073] It should also be noted that the physical neural operator accelerator adopts existing high-performance computing hardware and programmable accelerator technology, combines neural network computing optimization scheme, realizes fast processing of complex numerical operation and equation solving through hardware level parallel computing and instruction set optimization, realizes relying on existing GPU, FPGA or ASIC accelerator platform, using mature hardware interface and control protocol to drive operation, without building non-public computing device, ensuring that the energy control instruction can be efficiently executed and the calculation result is output.
[0074] The physical computing module uses three-dimensional geomechanics equations to perform analytical modeling, gridding, equation discretization and accelerated solving on the standardized space-time matrix under the constraint of the energy control instruction, extracts the mechanical field distribution and calculates the instability probability, and generates a disaster risk probability map.
[0075] It should be noted that the standardized space-time matrix of multi-modal heterogeneous data is closely combined with the energy control instruction, analytical modeling, gridding and equation discretization solving are realized based on three-dimensional geomechanics equations, and mechanical field distribution and instability probability are efficiently extracted through accelerated calculation, thereby generating a refined disaster risk probability map, realizing real-time closed-loop combination of data-driven physical modeling and disaster risk quantification, and significantly improving the accuracy and calculation efficiency of disaster risk prediction.
[0076] The beneficial effects are that by coupling the standardized space-time matrix of multi-modal heterogeneous data with the energy control instruction, analytical modeling, gridding and discretization solving are performed using three-dimensional geomechanics equations, which can extract the mechanical field distribution and calculate the instability probability in real time and high precision, thereby generating a disaster risk probability map. Unlike the disaster risk assessment in the prior art which usually relies on a single data source or static empirical model, the deep integration of multi-source data-driven, physical modeling and accelerated calculation is realized, which not only improves the accuracy and spatial resolution of disaster risk prediction, but also significantly reduces the calculation delay, realizes the real-time and dynamic adjustability of disaster risk quantification, and embodies the innovation in disaster intelligent perception and emergency data processing.
[0077] The standardized space-time matrix and the energy control instruction are analyzed, the space-time field variables and solving configuration are extracted, the three-dimensional calculation grid is mapped and updated, and the discrete grid model is generated through spatial interpolation assignment.
[0078] Further, the standardized space-time matrix and the energy control instruction are analyzed, the space-time field variables and calculation requirement parameters are extracted, and the space-time field variables and solving configuration are output.
[0079] Specifically, the time information, position coordinate information, meteorological sensor measurement data, hydrological sensor measurement data and geological sensor measurement data in the standardized space-time matrix are read, and the time information, position coordinate information, meteorological sensor measurement data, hydrological sensor measurement data and geological sensor measurement data are indexed and matched according to the space-time coordinate correspondence relationship; the energy control instruction is analyzed, the calculation mode code and energy constraint information are extracted, and the calculation resource and energy demand required by each spatial node are calculated by combining the task calculation requirement data in the standardized space-time matrix; the solving configuration is generated according to the calculation requirement parameters and the node position, including the time step, the equation type, the boundary condition and the grid division scheme; the space-time field variables and the solving configuration corresponding to each spatial node are output.
[0080] An initial mesh structure is generated according to the three-dimensional calculation region and the solving configuration, and a three-dimensional calculation mesh is output.
[0081] Specifically, the voxel blocks of the three-dimensional calculation region are divided according to the spatial boundary information of the three-dimensional calculation region, the block size, and the time step, the equation coupling parameter, and the solver setting in the solving configuration, the grid nodes uniformly distributed along the X-axis, the Y-axis, and the Z-axis are generated, the connection relationship between the nodes is established to form the initial mesh structure, and the initial mesh structure is output as the three-dimensional calculation mesh.
[0082] The spatiotemporal field variables are mapped to the three-dimensional calculation mesh, the grid density is adjusted according to the disaster risk probability map, the mechanical field distribution, and the energy state parameter of the previous calculation period, and the updated three-dimensional calculation mesh is output.
[0083] Specifically, the spatiotemporal field variables in the standardized spatiotemporal matrix are subjected to trilinear interpolation in space according to the node coordinates of the three-dimensional calculation mesh, and the interpolation results are written into the grid node attributes of the three-dimensional calculation mesh.
[0084] The risk value of the disaster risk probability map at the center, the stress or displacement value of the mechanical field distribution at the grid node, and the energy state parameter corresponding to the output power and the super capacitor power of the time step are obtained for each grid node of the three-dimensional calculation mesh, and the normalized value of the energy state parameter is calculated.
[0085] The risk value, the mechanical field gradient amplitude, and the normalized value of the energy state parameter are used to determine the local refinement or coarsening operation, for example, when the risk value exceeds the example high-risk standard or the mechanical field gradient amplitude exceeds the example high-gradient standard and the energy state parameter normalized value exceeds the example high-energy standard, it is marked for refinement, and when the risk value is lower than the example low-risk standard and the mechanical field gradient amplitude is lower than the example low-gradient standard or the energy state parameter normalized value is lower than the example low-energy standard, it is marked for coarsening.
[0086] Local octant or binary refinement is performed on the cubic block marked for refinement, new grid nodes are inserted, and the node connection relationship is updated, adjacent cubic blocks marked for coarsening and meeting the merging conditions are merged and redundant nodes are removed, and adjacent cubic blocks are adjusted for level consistency to maintain smooth transition of the grid resolution; finally, the updated three-dimensional calculation mesh is output.
[0087] The updated three-dimensional calculation mesh is subjected to spatial interpolation, and the spatiotemporal field variables are assigned to the grid nodes to generate a discrete grid model.
[0088] Specifically, according to the node coordinates of the updated three-dimensional calculation grid, the space interpolation processing is performed on the space-time field variables in the standardized space-time matrix, and the sensor measurement data at each time step and position is mapped to the corresponding grid node.
[0089] The existing three-dimensional interpolation method, such as trilinear interpolation or Kriging interpolation, is used to calculate the field variable values at the grid nodes, and the interpolated displacement, stress, temperature or measurement parameter is assigned to each grid node to generate a discrete grid model.
[0090] The initial mechanical conditions and boundary conditions are applied to the discrete grid model, and the coupling equation, time step and solver parameters are set according to the solving configuration to form a discrete equation system.
[0091] Specifically, according to the grid node information of the discrete grid model, the initial mechanical condition parameters and boundary condition parameters in the standardized space-time matrix are read, and the initial displacement, velocity, stress and temperature are assigned to the grid nodes of the discrete grid model, and the displacement constraint, force or pressure boundary condition is applied to the boundary nodes of the discrete grid model.
[0092] According to the equation type, time step and solver parameters in the solving configuration, the discretized three-dimensional geomechanical partial differential equation is assembled according to the grid node number, and combined with the initial conditions and boundary conditions, the mechanical coupling relationship between nodes is established, the combination of stiffness matrix, mass matrix and force vector is formed, the coupling equation is obtained, and the discrete equation system is output for numerical solution.
[0093] It should be noted that the solving configuration is derived from the standard numerical calculation method for solving three-dimensional geomechanical equations and engineering experience parameters, including the type of discretization method, time step setting, solver selection, boundary conditions and initial conditions parameters of the coupling equation, and the calculation accuracy and stability requirements obtained through experimental verification in similar geomechanical calculation tasks, which are used to ensure that the numerical solution of the discrete equation system can meet the accuracy and efficiency of disaster risk probability calculation.
[0094] The discrete equation system is loaded into the physical neural operator accelerator for numerical solution, and the mechanical field distribution is extracted.
[0095] Specifically, the discrete equation system is converted into a numerical input format recognizable by the physical neural operator accelerator according to the solver parameters and time step requirements, and the discrete equation system is loaded into the calculation program of the physical neural operator accelerator. The numerical iterative solution is performed in the physical neural operator accelerator according to the calculation mode and parallel operation strategy, and the space-time field variables of the grid nodes are periodically updated until the solving convergence condition is reached. The mechanical field distribution of each grid node, such as node displacement, stress and strain value, is output.
[0096] It should be noted that in the physical neural operator accelerator, when solving the discretized equation system iteratively, the change of the mechanical field distribution of each grid node in the three-dimensional calculation grid is calculated continuously to determine whether the change meets the preset convergence threshold. If the change of the mechanical field distribution of all grid nodes meets the convergence threshold, the solution is considered complete; if the change of the mechanical field distribution of some grid nodes does not meet the convergence threshold, the mechanical field distribution of the grid nodes is updated according to the time step and the next iteration is performed, and the process is repeated until the change of the mechanical field distribution of all grid nodes meets the convergence requirement, and finally the converged extraction mechanical field distribution is output.
[0097] The preset convergence threshold is determined according to the mechanical solution accuracy, the stability of the discretized equation, and the reliability of the disaster risk prediction, for example, the maximum allowed difference of the displacement or stress change of the grid node; specifically, the accuracy requirement is determined according to the resolution of the three-dimensional calculation grid and the time step, the convergence threshold is set for the sensitive area in combination with the disaster risk probability map, and the change of the mechanical field distribution of each grid node is compared with the convergence threshold in real time during the iterative solution process to determine the convergence.
[0098] The instability probability of the mechanical field distribution is calculated and spatially mapped to generate a disaster risk probability map.
[0099] Specifically, the mechanical field distribution obtained by the discretized equation system is analyzed node by node, and the node mechanical feature vector is formed according to the stress, strain and displacement data of the grid node; the node mechanical feature vector is compared with the preset instability judgment condition one by one, the instability probability is calculated node by node using the over-limit mapping method, and the instability probability of the grid node is arranged according to the node number to form a node instability probability matrix.
[0100] The node instability probability matrix is mapped to the spatial position coordinates of the three-dimensional calculation grid, a continuously distributed disaster risk probability map is generated through interpolation processing, and the disaster risk probability map is spatially smoothed and visually output to form a disaster risk probability map.
[0101] It should be noted that the preset instability judgment condition is determined according to existing geomechanics theory, three-dimensional geomechanics equation solving experience and disaster historical observation data, including the strength limit of rock and soil materials, friction angle, cohesion and parameters of typical instability modes, combined with the characteristics of the mechanical field distribution and the stress-strain critical value, obtained by field survey and experimental determination method, forming a set of judgment conditions that can be used to calculate the instability probability of the grid node.

[0103] The terrain height data in the existing digital terrain model database is adopted, and the terrain risk data set is formed by combining the disaster risk probability map.
[0104] Specifically, the terrain height data in the existing digital terrain model database is extracted, the terrain height information of the corresponding region is screened according to the spatial range of the disaster risk probability map, the terrain height of each grid node is matched with the disaster risk probability of the corresponding node, the terrain risk data set is generated according to the position of the grid node, for example, the terrain height value and the disaster risk probability value are formed into a two-dimensional table or a three-dimensional array for storage, and finally the terrain risk data set which can be used for subsequent communication node phase gradient calculation is formed.
[0105] The spatial coordinate difference and the height difference between the communication nodes are calculated by using the terrain risk data set, and the distance and height difference matrix between the nodes are obtained.
[0106] Specifically, according to the spatial coordinates and the terrain height of each communication node in the terrain risk data set, any two communication nodes are taken in turn and , the horizontal distance and the height difference between the nodes are calculated, the horizontal distance calculation expression is:
[0107]
[0108] Among them, represents the horizontal distance between the communication node and the communication node , the value of represents the value of the spatial coordinates of the communication node in the direction of the axis, the value of represents the value of the spatial coordinates of the communication node in the direction of the axis, the value of represents the value of the spatial coordinates of the communication node in the direction of the axis, the value of represents the value of the spatial coordinates of the communication node in the direction of the axis, the value of represents the number of the first communication node participating in the calculation, the value of represents the number of the second communication node participating in the calculation, the value range of and is , wherein is the total number of communication nodes;
[0109] The height difference calculation expression is:

[0111] wherein, represents a communication node and a communication node , represents a communication node , represents a communication node ;
[0112] All communication node combinations are calculated to obtain a distance and height difference matrix between nodes .

[0129] The encrypted fragments, encryption algorithm identifier, derived session key parameter, time stamp, and spatial coordinate label are encapsulated in a message format to output an encrypted data packet.
[0130] It should be noted that the preset master key is derived from a high-strength random number sequence generated by a key management center that has passed national commercial password detection and authentication, a 256-bit binary key is generated by a hardware true random number generator, is securely distributed by the key management center and is written into a secure storage area for encryption processing through a secure channel conforming to the national SM4 encryption algorithm, is loaded and solidified before deployment, and ensures the uniqueness and unpredictability of the preset master key during the entire use cycle.
[0131] The cloud collaboration module decrypts the encrypted data packet and performs three-dimensional disaster scenario deduction to generate a disaster impact heat map.
[0132] The encrypted data packet is decrypted to output a decrypted disaster risk probability map.
[0133] Specifically, the message header and payload of the encrypted data packet are read, and the encryption algorithm identifier, session key derivation parameter, initialization vector, message authentication code, data slice, timestamp and spatial coordinate label are parsed out;
[0134] Based on the preset master key and the derived session key parameter, the HKDF is used to derive the session key; then, based on the parsed initialization vector and the derived session key, the encryption algorithm (such as AES-GCM or ChaCha20-Poly1305) indicated in the message header is used to perform message authentication code verification and decryption operation on each data slice, and the integrity and sequence number (such as CRC check or sequence number comparison) of the decrypted slice are verified;

[0137] The decrypted disaster risk probability map is mapped to the discrete grid model nodes, the initial value of the mechanical field and the spatial boundary constraint condition are initialized, and three-dimensional disaster scenario deduction is performed to generate preliminary disaster simulation data.
[0138] Specifically, the decrypted disaster risk probability map is registered with the spatial coordinates of the discrete grid model nodes, and the risk value of each discrete grid model node is calculated based on trilinear spatial interpolation and written into the node attribute;
[0139] According to the node attribute, each discrete grid model node is given a mechanical field initial value, including node displacement initial value, stress initial value and velocity initial value;
[0140] Identify the boundary nodes of the discrete grid model and impose spatial boundary constraints according to the solving configuration, such as fixed displacement boundary, force / pressure boundary or seepage boundary parameters; according to the solving configuration, use explicit or implicit time integration scheme to carry out three-dimensional disaster deduction on the discretized equation set, update the mechanical field of the discrete grid model nodes according to time step and carry out necessary numerical stability and convergence check;
[0141] Organize and export the field variables of the discrete grid model nodes at each time step according to spatial grid points and time sequence to generate preliminary disaster simulation data.
[0142] Fuse the preliminary disaster simulation data with the meteorological and hydrological observation data measured by the field sensors, and carry out three-dimensional disaster deduction again to generate disaster impact heat map.
[0143] Specifically, read the preliminary disaster simulation data and the meteorological and hydrological observation data measured by the field sensors, and perform spatial and temporal interpolation registration of the meteorological and hydrological observation data measured by the field sensors to the discrete grid model nodes according to time stamp and spatial coordinates;
[0144] Calculate the node-by-node deviation of the observation value and the preliminary disaster simulation data at the registered nodes, and use existing data assimilation methods (such as least squares incremental correction or ensemble Kalman filter) to apply the deviation as a correction term to the mechanical field initial value and boundary conditions of the discrete grid model nodes, and output the corrected discrete grid initial value and boundary conditions;
[0145] Based on the corrected discrete grid initial value and the solving configuration, perform three-dimensional disaster deduction according to the time integration scheme specified by the solving configuration, update the grid node field variables step by step until the simulation period is completed, and export the time series field data of the three-dimensional disaster deduction;

[0147] It should be noted that the source of the influence index calculation rules is the published disaster assessment industry standards, meteorological and hydrological monitoring technical specifications, and historical disaster statistical analysis results, and the calculation factors and weight distribution are determined combined with the typical physical characteristics of the target disaster type, for example, according to the national or industry disaster risk assessment standards to determine rainfall intensity, runoff, slope stability coefficient, etc. as evaluation factors, and reference the influence range and loss degree caused by the same disaster in the historical disaster database to determine the weight and range of each evaluation factor, forming a quantifiable and repeatable influence index calculation rule.
[0148] The rescue decision module uses an improved path planning algorithm to optimize the disaster influence thermal map, generates an optimized rescue path, and combines communication energy consumption data and backhaul terrain parameters to generate updated communication power and redundancy configuration parameters.

[0150] The beneficial effects are that by integrating the disaster influence thermal map, communication energy consumption data and backhaul terrain parameters in the rescue decision module, the unified optimization of rescue path optimization and communication resource collaborative scheduling is realized. Unlike the existing technology which usually relies on only single geographic information or disaster risk information for path planning, the communication power distribution and beamforming redundancy can be dynamically adjusted to keep the communication link in the key area stable in the high-risk area, while saving energy in the low-risk area, thereby forming a closed-loop optimization mechanism of disaster situation awareness, path planning and communication management. The efficiency and communication reliability of emergency rescue are significantly improved, which is suitable for disaster scenarios with limited energy and complex communication environment, and embodies the innovation and practicality of the integration of path planning and communication support.

At the same time, the grid with obstacles is determined according to the comparison of the risk value and the obstacle judgment threshold, and the spatial coordinates and attribute information of the obstacles are recorded. The risk level and obstacle information are organized according to the grid order to form the path planning input data.
[0153] It should also be noted that the preset risk level is divided into different levels according to the geological disaster, meteorological and hydrological historical data statistics and disaster influence index calculation rules, such as low, medium and high levels, to reflect different degrees of potential danger; the obstacle judgment threshold is determined according to the field sensor measurement data and historical obstacle distribution characteristics, for example, by analyzing the obstacle probability distribution, the obstacle judgment threshold is set to an example value of 0.7 to ensure that the path planning input data can accurately reflect the actual obstacle distribution situation.
[0154] According to the path planning input data, the initial parameters and heuristic function of the improved path planning algorithm are initialized, the path search is performed and the candidate path cost is evaluated, the path selection is optimized, and the preliminary rescue path is generated.
[0155] Specifically, the risk level and obstacle information of each grid in the path planning input data are read, the improved path planning algorithm is initialized according to the heuristic function and initial parameters, the start point and the end point grids are added to the search queue, the path cost of the candidate path in the queue is calculated in turn, including the path length, the risk level cumulative value and the obstacle avoidance cost, the optimal candidate path is selected according to the cost sorting, and the search queue and the path state are updated, and the search is repeated until the end point is reachable, and finally the preliminary rescue path sorted by the optimal cost is output.
[0156] For example, the example path length weight in the heuristic function is 0.5, the risk level weight is 0.3, and the obstacle avoidance weight is 0.2.
[0157] The heuristic function is derived from the classical heuristic search method in the field of artificial intelligence path planning, such as Manhattan distance, Euclidean distance or weighted distance function used in A* algorithm, which is improved in combination with the risk level and obstacle information in the path planning input data to guide the search to preferentially explore areas with high safety and low path cost, and to realize effective path search.
[0158] The preliminary rescue path is smoothed and adjusted in risk to generate an optimized rescue path.
[0159] Specifically, the node coordinates of the preliminary rescue path are read, the line segments between adjacent nodes are smoothed using a curve fitting method, the nodes in the curve located in the high-risk area or close to the obstacle are adjusted according to the path risk level and obstacle judgment threshold in the path planning input data, the node coordinates are recalculated and the path order is updated to form the optimized rescue path.
[0160] The high-risk area coordinates are extracted from the optimized rescue path to trigger the correction of the beamforming matrix control parameters to generate corrected communication parameters.
[0161] Specifically, the node coordinates of the optimized rescue path are read, the nodes located in the high-risk area are selected and the spatial coordinates are extracted, the phase modulation value and amplitude distribution of the beamforming matrix are adjusted according to the high-risk area coordinates, the control parameters of the array elements are recalculated, and the corrected communication parameters are generated.
[0162] The communication link quality indicators are monitored and collected, the link power consumption and energy consumption are calculated in combination with the corrected communication parameters, the energy consumption feedback information is generated, and the comprehensive energy state data is generated after fusion processing.
[0163] Specifically, the communication link quality indicators are collected and parameters such as signal strength, signal-to-noise ratio and bit error rate are recorded, the instantaneous power consumption and cumulative energy consumption of each communication link are calculated according to the modified communication parameters, the energy consumption feedback information is generated by integrating the power consumption and energy consumption of each link, the energy consumption feedback information is fused with the communication link quality indicators, and the comprehensive energy state data is obtained.
[0164] The adaptive optimization algorithm is used to analyze the comprehensive energy state data, dynamically adjust the communication power distribution ratio and the redundancy setting of the beamforming matrix, and generate updated communication power and redundancy configuration parameters.
[0165] Specifically, the comprehensive energy state data is read and normalized, the communication link power consumption, energy consumption and signal quality indicators are taken as input features, the adaptive optimization algorithm is used to calculate the adjustment amount of the communication power distribution ratio and the optimization value of the beamforming matrix redundancy, and the communication power distribution ratio and the beamforming matrix redundancy setting are updated according to the optimization results, and finally the updated communication power and redundancy configuration parameters are generated for subsequent communication control.
[0166] It should be noted that the optimized rescue path and the updated communication power and redundancy configuration parameters are obtained by multi-modal fusion processing of the disaster influence thermal map, communication energy consumption data and backhaul terrain parameters, which realizes intelligent sensing and emergency data engineering operation in potential disaster environment, and the communication power and redundancy parameters are used as feedback signals to dynamically adjust the rescue path planning and communication support strategy.
[0167] In summary, the present application realizes the closed-loop optimization mechanism of disaster situation awareness, task demand and communication resource management by real-time triggering of beamforming matrix control parameter modification, and dynamically adjusting the communication power and redundancy in combination with link quality monitoring and adaptive optimization algorithm, greatly improves the reliability and energy utilization efficiency of emergency communication, ensures the stability and redundancy of communication link in critical areas, and saves resources in low-risk areas, and is suitable for emergency rescue scenes with limited energy and complex communication environment.
