[0033] The knowledge graph management module is used to perform management operations of storing, querying, updating, and maintaining the constructed knowledge graph, ensuring the integrity and consistency of the knowledge graph, improving the usability and reliability of the knowledge graph, and providing stable knowledge support for analysis and applications;

[0034] The analysis and application module provides multiple analysis and application functions based on the knowledge graph.

[0036] Embodiment 2

[0037] As attached Figure 1 As shown, this embodiment is basically the same as the previous embodiment, with the difference that the structured data collected by the data acquisition module include equipment operating parameters and production order data, the semi-structured data include log files, and the unstructured data include equipment maintenance manuals and process documents. It can collect various types of data in the industrial Internet in a variety of ways, provide sufficient data support for subsequent data preprocessing and knowledge graph construction, and improve the integrity and accuracy of the data.

[0038] Specifically, the data preprocessing module uses a data cleaning algorithm to remove noise data and duplicate data, uses a data conversion algorithm to convert data into a unified format, and uses a data integration algorithm to integrate data from different data sources to improve data quality and availability, providing a high-quality data foundation for knowledge graph construction.

[0039] Furthermore, the knowledge graph construction module uses a named entity recognition algorithm to extract entities from text data, a relationship extraction algorithm to extract relationships from text data, and an attribute extraction algorithm to extract attributes from text data. Entities include equipment, processes, products, and personnel. Relationships include the association between equipment, the sequence of process steps, and the correspondence between products and equipment. Natural language processing, information extraction and other technologies are used to extract entities, relationships, and attributes from preprocessed data to construct an industrial Internet service knowledge graph, integrating scattered data into a knowledge graph with semantic relationships to provide rich knowledge support for subsequent analysis applications.

Compared with the existing technology that can only process a single data type, it has more comprehensive data processing capabilities and can better meet the processing needs of complex data in the industrial Internet. The analysis model based on graph neural network can make full use of the topological structure information in the knowledge graph and explore deeper knowledge associations and potential laws. Compared with the existing technology, the analysis accuracy is higher and it can provide more accurate analysis results and decision-making recommendations for industrial Internet services.

[0042] Embodiment 3

[0043] As attached Figure 1 As shown, this embodiment is basically the same as the previous embodiment, except that the propagation and aggregation process of the analysis model based on the graph neural network is represented by the following formula: $h_i^{(k+1)}=\sigma\left(\sum_{j\in N(i)}\frac{1}{\sqrt{|\mathcal{N}

[0044] (i)|\sqrt{|\mathcal{N}(j)|}}W^{(k)}h_j^{(k)}\right)$

[0045] Among them, $h_i^{(k)}$ represents the representation vector of node $i$ in module $k$, $N(i)$ represents the set of neighbor nodes of node $i$, $W^{(k)}$ represents the weight matrix of the $k$-th module, $\sigma$ represents the activation function, and $|\mathcal{N}(i)|$ represents the number of neighbor nodes of node $i$. This formula updates the representation vector of the node by aggregating the information of neighbor nodes and combining the features of the node itself. This mechanism enables each node to learn the feature information of its neighbor nodes, thereby better capturing the topological relationship in the graph structure.

[0046] Specifically, the analysis model based on the graph neural network is trained using the supervised learning method. The model is trained using labeled data, and the labeled data includes fault diagnosis results, production optimization suggestions, and equipment maintenance plans. During the training process, the analysis model updates the weights by minimizing the loss function, such as cross-entropy loss or mean squared error loss, thereby improving the prediction accuracy of the model.

[0047] Furthermore, when the analysis model based on the graph neural network is applied, it is used for fault diagnosis and prediction, production optimization suggestions, equipment maintenance plan formulation, and process improvement plan recommendation. Specifically, it includes: using the model to analyze the equipment nodes in the knowledge graph to predict the fault probability of the equipment. By analyzing the equipment nodes in the knowledge graph, the model can learn the associations and fault patterns between equipment, thereby realizing early warning of potential faults; using the model to analyze the process nodes in the knowledge graph to optimize the process flow. By analyzing the process nodes, the model can optimize the production process, discover bottleneck links in the production process, and provide optimization suggestions, thereby improving production efficiency; using the model to analyze the equipment nodes in the knowledge graph to formulate equipment maintenance plans. According to the operating status and fault prediction results of the equipment, personalized equipment maintenance plans are generated, and the maintenance time and resources are reasonably arranged; using the model to analyze the process nodes in the knowledge graph to recommend process improvement plans. By analyzing the process nodes, improvement plans are recommended to improve the process level and product quality.

[0048] Furthermore, the analysis application module provides analysis application functions for fault diagnosis and prediction, production optimization suggestions, equipment maintenance plan formulation, and process improvement plan recommendation, and displays the analysis results in a visual way. The visual display not only facilitates the user to intuitively understand the analysis results, but also can quickly locate problems and take corresponding measures.

[0049] Furthermore, the platform can run in real time in the industrial Internet environment, monitor and analyze the equipment status and production process in real time. By collecting equipment operating parameters, production order data, etc. in real time, the platform can promptly detect equipment failures and problems in the production process, and perform real-time analysis and prediction through an analysis model based on graph neural networks.

[0050] From the above, we can see that this platform realizes efficient processing and in-depth analysis of industrial Internet data by constructing an industrial Internet service knowledge graph and combining it with an analysis model based on a graph neural network. It can improve the accuracy of fault diagnosis, optimize production processes, and improve equipment maintenance efficiency. The graph neural network can make full use of the topological structure information in the knowledge graph to mine the associations and failure modes between equipment, thereby improving the accuracy of fault diagnosis. By analyzing process nodes, the model can discover bottlenecks in the production process and provide optimization suggestions to improve production efficiency. According to the operating status of the equipment and fault prediction results, it can generate personalized equipment maintenance plans, reasonably arrange maintenance time and resources, and integrate and display various types of knowledge in the industrial Internet in the form of a knowledge graph, which is convenient for knowledge sharing and inheritance among internal personnel of the enterprise.
