[0031] Reference Figure 1 , an embodiment of the present invention proposes an artificial intelligence-based simulation data monitoring and analysis system, comprising:
[0032] The intelligent sensing module 100 is used for multi-source data fusion and collection, and includes:
[0033] The heterogeneous protocol adapter unit 110 is used to support automatic conversion between Modbus / TCP, OPC UA, and MQTT protocols. This embodiment utilizes a two-layer input-output conversion architecture to achieve automatic multi-protocol conversion. The input layer receives raw protocol data packets, and the protocol parsing engine automatically identifies the protocol type based on packet characteristics (Modbus / TCP based on function codes, OPC UA based on NS0 header identification, and MQTT based on topic levels). The data structures of different protocols are then deconstructed into an intermediate common data model. The output layer dynamically binds source protocol tags to target protocol nodes through a field mapping table, completing data type conversion (e.g., Modbus register values to OPC UA Variant types) and semantic adaptation (e.g., mapping MQTT topic trees to OPC UA address spaces). The data packets are then repackaged according to the target protocol specifications, with a quality verification module verifying data integrity and timing consistency. This process utilizes a stateless design, with conversion rules continuously optimized through online learning, ultimately achieving bidirectional transparent transmission between protocols.
[0034] A time-space alignment unit 120 is configured to implement microsecond-level data alignment using the PTP time synchronization protocol;
[0035] The data quality assessment unit 130 is used to detect abnormal sampling values in real time based on the isolation forest algorithm. The data quality assessment unit 130 of this embodiment receives a multi-dimensional time series data stream from a sensor or control system as input through an algorithm, first performs standardization preprocessing on the data to eliminate dimensional differences, and then constructs a set of randomly divided isolation trees. Abnormal values can be quickly identified because they usually have a shorter path length in the tree structure. The detection result is output as an abnormality score with confidence, and the abnormal time point and feature dimension are marked. In industrial scenarios, data anomalies often hide key information, and traditional threshold methods are difficult to deal with complex correlated anomalies. In equipment health management, this embodiment can capture sensor drift or sudden fault signals in real time to avoid misdiagnosis; for process optimization, this embodiment can identify abnormal operating data that deviates from the normal parameter range to ensure the data quality of the training model.
[0036] The dynamic modeling module 200 is used to build an evolvable simulation model and realize the adaptive evolution of the simulation model through a multi-level technical architecture. In this embodiment, the digital twin is used to map the equipment degradation process in real time in equipment health management, and a closed-loop prediction model of parameters and performance is built in process optimization. The dynamic modeling module drives the continuous evolution of the model through real-time data flow. Its input is equipment operating parameters, environmental variables and historical performance data, and its output is a prediction result with confidence assessment. The model evolution trigger mechanism is based on three criteria: 1) triggering parameter recalibration when the online error index exceeds the threshold; 2) starting structural optimization when data distribution drift is detected; 3) performing model attenuation compensation updates regularly. The data processing adopts a sliding window mechanism. After feature extraction, the data in the window is used for both real-time prediction and model iterative training.
[0037] The dynamic modeling module 200 of this embodiment includes:
[0038] The parametric modeling unit 210 is used to encode the geometric features and physical properties of the device into a programmable parameter vector. The geometric feature encoding is based on the MLP network, and the geometric constraints are mathematically expressed using the Lagrange multiplier method. It supports automatic parameter optimization through error gradient back propagation. The formula is as follows: ; Where y is the physical quantity measurement value of the simulation target, θ is the trainable parameter vector, is a neural network prediction model, g(X) is a physical constraint function, and λ∈(0,1) is the constraint strength coefficient. The parametric modeling unit 210 of this embodiment implements a digital representation of device features using a structured coding framework. Its operating principle is as follows: It inputs 3D device geometric topology data (such as a boundary representation or voxel grid) and physical property data (such as material parameters and operating constraints). A feature extraction network first decomposes the geometric structure into hierarchical parameter groups (such as shape parameters and connectivity parameters), while simultaneously quantizing the physical properties into differentiable variables. A dual encoding strategy is employed during the data processing phase: geometric features are embedded using a graph neural network, and physical properties are converted into a standardized parameter space using a normalization layer. The output is a programmable parameter vector of uniform dimension, each dimension of which is differentially mapped to a device performance indicator. Upon receiving real-time sensor data, the system calculates the error gradient between the predicted output and the actual measurement, and then backpropagates adjustments along each dimension of the parameter vector to achieve automatic parameter optimization. This process maintains the mathematical integrity of the geometric constraints and physical laws, ensuring that the optimized parameter combination consistently meets engineering feasibility.
[0039] The physics engine coupling unit 220 is used to integrate the outputs of different solvers through a multi-scale modeling framework, use a dynamic time warping algorithm to synchronize the time steps across solvers, and eliminate cross-domain simulation deviations using a weighted fusion algorithm based on residual analysis. The weights of the weighted fusion algorithm are: ;in, is the fusion weight of the i-th solver, is the residual vector, Represents the Euclidean norm, and the weight range satisfies . The physical engine coupling unit 220 of this embodiment realizes cross-domain simulation collaboration through a multi-scale modeling framework, and its working principle is: input the spatiotemporal discrete data output by each physical field solver (such as structural stress field, fluid velocity field, etc.), first establish a scale correlation matrix, and map the simulation data of different resolutions to a unified reference system. An adaptive weighted fusion algorithm is adopted in the data processing stage to dynamically adjust the fusion weight based on the confidence index of each solver, where the confidence is double-verified by residual analysis and energy conservation rate. The output is composite physical field data that eliminates scale conflicts, and its deviation rate is controlled within the preset tolerance range.
[0040] The model validation unit 230 is used for global sensitivity analysis of variance decomposition based on a sliding window. The window length is automatically adjusted according to the coefficient of variation of the parameters, dynamically identifying key parameters and optimizing the allocation of computing resources. The formula for automatic adjustment of the window length is as follows: ; Where L(t) is the window length at time t, is the coefficient of variation, which is the ratio of the standard deviation to the mean and is used to quantify the degree of dispersion of the parameter; where s0 represents the maximum and minimum window lengths, respectively; k represents the slope factor of the sigmoid function, controlling the sensitivity of window length changes; and s0 represents the critical threshold of the coefficient of variation. k and s0 are preset parameters derived from cross-validation of historical simulation datasets. The model validation unit 230 of this embodiment inputs a parameter space sampling dataset (containing system response values for various parameter combinations). It first constructs a Sobol index calculation framework, decomposing the total variance into individual parameter contributions and interaction terms. During the data processing phase, the Monte Carlo integration method is used to calculate first-order and higher-order sensitivity indices, quantifying parameter importance using variance contribution ratios. A ranked parameter sensitivity list and confidence intervals are output, with parameters whose contribution ratios exceed the threshold being marked as critical parameters. Based on these analysis results, the system dynamically adjusts computing resource allocation: sampling density and iteration counts are increased for critical parameters, while computational accuracy requirements are reduced for non-critical parameters. The entire process employs an adaptive sampling strategy to minimize computational overhead while ensuring analytical accuracy.
[0041] In some embodiments, the system of an embodiment of the present invention also includes: an edge computing module for realizing distributed processing of near data sources, including: a model acceleration unit for deploying lightweight inference models optimized by hardware awareness, and the optimization includes at least one of the following technologies: numerical precision quantization, computational graph operator fusion, and target hardware instruction set adaptation.
[0042] In some embodiments, the edge computing module of an embodiment of the present invention includes: a streaming storage unit for adopting a time series-sensitive cache management strategy, the cache management strategy including: event-triggered data coverage rules, a dynamically adjusted window size mechanism, and multi-priority data shard storage.

[0044] In some embodiments, the system of the present invention includes an intelligent warning module for dynamically generating graded warning signals based on simulation data, including:
[0045] Composite event detection unit, used to perform multi-dimensional anomaly correlation analysis:
[0046] ;
[0047] in, is the deviation degree of the physical constraint of type i, which is calculated by the Hellinger distance between the real-time simulation value and the theoretical value; is the statistical anomaly score, which is obtained by normalizing the standard deviation of the residual distribution output by the dynamic modeling module; α, β∈[0,1] are weight coefficients, satisfying α+β=1, and τ is the dynamically adjusted expert experience threshold.
[0048] The "abnormalities" involved in the intelligent early warning module in this embodiment include but are not limited to the following two categories: (1) Inconsistency between the simulation model and the physical laws, which is manifested in the simulation data (such as temperature field distribution, stress-strain curve) violating the preset physical constraints (such as energy conservation, material constitutive equation). The root cause of the abnormality is that the actual state of the simulation object (such as equipment, process system) deviates from the normal operating mode, which may cause equipment failure or process out of control. For example: the stress simulation value of the turbine blade exceeds the material yield limit → warning that the blade may undergo plastic deformation. (2) Significant deviation of data-driven statistical characteristics, which is manifested in the time series distribution of the monitoring data (such as residual fluctuation, multi-parameter correlation) significantly deviating from the statistical characteristics of historical normal operating conditions. The root cause of the abnormality may be sensor drift, unmodeled external interference (such as environmental mutation) or hidden failure mode (such as wear accumulation). For example: the variance of the hydraulic system pressure fluctuation suddenly increases by 3 standard deviations → warning of seal leakage risk.
