The wind power tower, as the key supporting structure of the wind turbine generator, its manufacturing quality directly affects the stability and power generation efficiency of the wind turbine generator. However, the traditional wind power tower manufacturing process has the following technical bottlenecks, which restricts the improvement of production efficiency and product quality:

[0003] 1. Wind power tower manufacturing involves multi-link coordination (such as welding, cutting, assembly), but the existing production mode relies on manual experience and offline data recording, which leads to: data fragmentation: production equipment, process and product quality detection data are scattered in different systems, and there is a lack of unified integration platform; decision lag: production plan is made depending on static report, which cannot respond to equipment failure, raw material shortage or order priority change in real time, resulting in unstable delivery cycle; process parameter out of control: key process parameters rely on manual adjustment by workers, and different batches of products have poor consistency.

[0004] 2. Production plan preparation mainly relies on traditional manual experience and static scheduling model, and the traditional planning system cannot integrate dynamic variables such as equipment failure, raw material shortage and personnel skill matching in real time, resulting in frequent plan adjustment. Tower production involves plate rolling, welding, corrosion prevention and other processes, and the traditional planning mode is difficult to coordinate the coupling relationship of equipment capacity, personnel skills and material supply, often resulting in process waiting or resource overload.

[0005] Therefore, the present application proposes a wind power tower manufacturing digital operation coordination system and method to realize technical breakthrough. SUMMARY

[0038] Equipment maintenance submodule: for real-time monitoring of production equipment, collecting operation state data of the equipment,

[0039] Further, video monitoring equipment or image recognition device is also deployed in the data acquisition module, for collecting image data and transmitting to the data processing module;

[0040] A data fusion module is further arranged to receive different types of data from the data acquisition layer module, perform data synchronization, alignment and fusion processing, and form comprehensive data.

[0041] A wind power tower manufacturing digital operation collaboration method, comprising the following steps:

[0042] Production plan intelligent execution step: according to the production plan generated by the production plan management sub-module, execute the production task, monitor the production progress in real time, and ensure that the production plan is carried out according to the plan;

[0043] Process parameter accurate execution step: the process control sub-module establishes a process parameter database, collects process parameters in real time through sensors, compares them with standard parameters in the process parameter database, sets different deviation thresholds, takes different warning and adjustment measures according to the deviation degree, and when the parameters deviate, sends out a warning in time and automatically adjusts the equipment parameters to ensure that the process parameters meet the standard requirements;

[0044] Quality defect traceability step: for the detected welding porosity or crack defects, associate production batch, operator, equipment state and environmental parameters, generate a root cause analysis report and push it to the responsible department.

[0045] Further, it further includes a multi-source data fusion processing step: after the multi-source data is collected by the data acquisition layer module, the multi-source data fusion module performs data synchronization, alignment and fusion processing to form a comprehensive data view.

[0046] Further, the multi-source data fusion processing step:

[0047] Data synchronization and alignment ensure that data from different data sources are synchronized in time stamp and necessary data alignment processing is performed to eliminate time delay and misplacement between data;

[0048] Data fusion algorithm: adopt data fusion algorithm to fuse the multi-source data, improve the accuracy and reliability of the data;

[0050] Comprehensive data view generation: generate a comprehensive data view according to the fused data to provide intuitive and comprehensive data display for subsequent data analysis and application.

[0051] Further, the data fusion algorithm includes:

[0052] State prediction:

[0053] X k|k-1 = F k ·X k-1|k-1+B k ·U k ;

[0054]

[0055] wherein X k|k-1 is a state prediction value; X k-1|k-1 is a state estimation value at a previous time; F k is a state transition matrix; B k is a control input matrix; U k is a control input; P k|k-1 is a prediction covariance matrix; P k-1|k-1 is a covariance matrix at a previous time; Q k is a process noise covariance matrix; is a transpose matrix of the state transition matrix F k ;

[0056] Measurement update:

[0057]

[0058] X k|k = X k|k-1 + K k ·(Z k -H k ·X k|k-1 );

[0059] P k|k =(I-K k ·H k )·P k-1|k-1 ;

[0060] wherein K k is a Kalman gain, H k is a measurement matrix, is a transpose matrix of the measurement matrix H k , Z k is a measurement value, R k is a measurement noise covariance matrix, X k|k is a state estimation value, P k|k is a covariance matrix, and I is an identity matrix.

[0061] Further, in the data fusion process, anomaly detection is achieved by the following steps:

[0062] Statistical features and business rules joint detection: calculate the statistical feature quantity of data distribution, mark the outliers exceeding the preset threshold, and at the same time, construct a business rule engine based on domain knowledge to logically check the data rationality;

[0063] Cross-sensor consistency verification: Kalman filter algorithm is used to estimate the state of multi-source sensor data, calculate the residual and detect the anomaly, if the residual exceeds the dynamically adjusted confidence interval, it is marked as potential anomaly;

[0064] Deep learning time series modeling: LSTM-Autoencoder model is used to encode and reconstruct time series data, and unknown mode anomaly is identified by comparing reconstruction error with adaptive threshold value;

[0065] Among them, the dynamically adjusted confidence interval is updated in real time according to the historical data volatility rate, and the adaptive threshold value is dynamically generated based on the percentile of the reconstruction error of the training set.

[0066] Further, the abnormality processing step comprises:

[0067] Hierarchical repair strategy: the detected abnormal data is classified according to the severity, wherein the fatal abnormality immediately triggers system alarm and terminates the fusion process, and the recoverable abnormality is repaired according to the data type by selecting interpolation method or regression prediction method;

[0068] Dynamic weight fault tolerance mechanism: for the data source containing abnormality, its weight value is reduced in the fusion process.

[0069] By adopting the foregoing technical solutions, the present application has the following beneficial effects:

[0070] 1. By deploying temperature, pressure, displacement, vibration, current and other multi-type sensors, a three-dimensional data sensing network covering production equipment, process and product quality is constructed, solving the problem of "equipment-process-quality" data fragmentation in traditional manufacturing. The modular architecture of data acquisition layer, processing layer and application layer supports flexible expansion, realizing real-time data sensing and closed-loop control of the whole process of wind turbine tower manufacturing. The problem of data island in traditional manufacturing is solved, the production transparency is improved, and data support is provided for process optimization and equipment maintenance, significantly reducing the risk of unplanned downtime.

[0071] 2. The improved genetic algorithm simulates the natural selection mechanism to achieve Pareto optimal solution among equipment capacity, personnel skills, raw material supply and order priority, realizing dynamic balance of multiple objectives. In view of the defect that genetic algorithm is easy to fall into local optimum, fuzzy rules are introduced to dynamically adjust the weight of uncertain factors (such as sudden shortage of raw materials), realizing fuzzy comprehensive evaluation compensation. The algorithm output can include visual tools such as equipment load thermal map and personnel skill matching matrix, helping dispatchers quickly locate bottleneck links and realize visual decision support.

[0072] 3. New sub-modules for quality inspection and equipment maintenance have been added. By monitoring weld quality, dimensional accuracy, and equipment operating status in real time, defect tracing and preventative maintenance are achieved. This design reduces the defect rate, extends equipment life, and promotes process improvement through root cause analysis reports, thereby lowering quality costs.

[0073] 4. Video surveillance equipment and image recognition devices were deployed, and a data fusion module was added to achieve multimodal data synchronization and comprehensive analysis. This technology solves the problem of the one-sidedness of data from a single sensor, improves the accuracy of anomaly detection (such as equipment failure and process deviation), and provides intuitive decision support for management through a comprehensive data view.

[0074] 5. Precise Execution of Process Parameters: By comparing sensor data with a standard parameter library in real time, a three-level early warning mechanism is automatically triggered (yellow warning - parameter drift, orange warning - approaching threshold, red warning - exceeding tolerance and shutdown). Intelligent Execution of Production Plans: Combining equipment status monitoring data, the sequence of processes is dynamically adjusted. This ensures that production proceeds according to plan, while real-time parameter comparison and automatic adjustment guarantee process stability and reduce quality fluctuations caused by human intervention.

[0075] 6. The multi-source data fusion processing step solves the spatiotemporal inconsistency problem of heterogeneous data (such as numerical values, images, and text) through data synchronization, alignment, and fusion. This technology improves data integrity and usability, provides a high-quality data foundation for subsequent analysis, and supports accurate decision-making.

[0076] 7. An anomaly detection and handling mechanism was introduced during the data fusion process. Through statistical features, business rules, cross-sensor consistency verification, and deep learning models, multi-level anomaly identification and isolation were achieved. This design avoids interference from anomalous data with the analysis results, improves system robustness, and reduces the impact of erroneous data through dynamic weight adjustment.

[0077] 8. A Kalman filter algorithm for state prediction and measurement updates was adopted to achieve dynamic estimation and noise filtering of time-series data. This algorithm improves the accuracy of data prediction and is particularly suitable for high-frequency vibration or temperature fluctuation scenarios, providing a reliable basis for equipment health management.

[0078] 9. By jointly detecting statistical features and business rules, verifying cross-sensor consistency, and using LSTM-Autoencoder time-series modeling, intelligent identification of unknown anomaly patterns is achieved. This technology overcomes the limitations of traditional rule engines, can adaptively learn changes in data distribution, and improves the coverage of anomaly detection.

[0079] 10、Hierarchical repair strategy and dynamic weight fault tolerance mechanism balance system real-time and data reliability by differentiating between fatal exceptions and recoverable exceptions. At the same time, dynamic weight adjustment reduces the fusion contribution of abnormal data sources, avoids the "bucket effect", and improves the overall data quality.
