Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0015] Example 1 Figure 1 This is a flowchart of a multi-view data display method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where industrial anomaly data is displayed in multiple views as needed. The method can be executed by a multi-view data display device, which can be implemented in hardware and / or software, and can be integrated into an electronic device with data processing capabilities. Figure 1 As shown, the method includes: S101, the data receiving service unit receives industrial data messages sent by each heterogeneous connector through the data bus, and sends the industrial data messages to the data modeling engine.

[0016] This embodiment is mainly applied to multi-view modeling systems, such as... Figure 2 The diagram shows the system's structure. The multi-view modeling system includes an Object Linking and Embedding for Process Control Unified Architecture (OPC UA) address space unit, a data modeling engine and a knowledge graph unit connected to the OPC UA address space unit, and a unified interface service layer connected to the OPC UA address space unit and the knowledge graph unit. The multi-view modeling system communicates with multiple heterogeneous connectors via a data bus. Each connector connects to different types of industrial data sources, such as sensors, programmable logic controllers (PLCs), or supervisory control and data acquisition (SCADA) systems. This implementation can be applied to industrial data analysis scenarios. However, this implementation is merely illustrative and does not limit the type of industrial data source or the content of the collected data. After receiving industrial data from each heterogeneous connector, the data bus performs standardized conversion according to JSON format to obtain industrial data messages. Each industrial data message contains multiple data entries from the same heterogeneous connector. The data receiving service unit receives industrial data messages in real time and performs preliminary preprocessing operations such as verification, buffering, and classification. Finally, it sends the preprocessed industrial data messages to the data modeling engine.

[0017] S102, the data modeling engine constructs a basic model based on the industrial data message, and the basic model is saved and maintained by the OPC UA address space unit.

[0018] Optionally, constructing a basic model based on the industrial data message using the data modeling engine includes: extracting hierarchical metadata from the industrial data message using the data modeling engine, wherein the hierarchical metadata includes objects and hierarchical relationships between objects, and the types of objects include factories, branches, work areas, equipment, and measurement points; converting each object in the OPC UA address space unit according to the OPC UA protocol to obtain the converted objects; and associating the converted objects with related relationships according to the hierarchical relationships to construct the basic model.

[0019] Optionally, the basic model is saved and maintained through the OPC UA address space unit, including: saving the basic model in a specified spatial location through the OPC UA address space unit; when it is determined that there is updated information based on the latest industrial data message sent by the data receiving service unit, the basic model is adjusted according to the updated information, wherein the updated information includes object update information or hierarchical relationship update information.

[0020] In this embodiment, the data modeling engine, upon receiving industrial data messages with multi-source, heterogeneous, and sequential characteristics, establishes a unified and standardized basic model based on the industrial data messages. The core of this basic model is a hierarchical structure built from macro to micro levels, based on the physical composition and affiliation of industrial assets. This basic model systematically describes the complete hierarchical relationship from the group to the bottom measurement point in a top-down manner. For example, a typical structure of this basic model can be represented as follows: Of course, this implementation method is only an example and does not limit the specific structural form of the basic model.

[0021] In one specific implementation, the data modeling engine automatically parses industrial data messages and obtains hierarchical metadata. This metadata includes objects and their hierarchical relationships. Object types include groups, branches, factories, work areas, equipment, and measuring points. Hierarchical relationships can include subordinate, parallel, or limiting relationships. For example, when an industrial data message is received for the first time, parsing it yields objects such as "Factory A - Work Area 1 - Machine Tool X - Spindle Temperature," with subordinate relationships between these objects. Since the data modeling engine primarily creates models within OPC UA address space units, it converts each object according to the OPC UA protocol to obtain the converted objects, ensuring the format matches the OPC UA address space units. Based on predefined model structure rules and hierarchical relationships, it associates the converted objects to construct the basic model. The entire model construction process requires no manual intervention, achieving real-time and automated mapping from data flow to object models. This significantly reduces the manual configuration and coding workload required by traditional methods, greatly improving modeling efficiency, accuracy, and maintainability.

[0022] It should be noted that in this embodiment, after the basic model is constructed, it will be saved in the OPC UA address space unit. The OPC UA address space unit is responsible for the subsequent maintenance of the initially established basic model. For example, when the latest industrial data message is received, the latest industrial data message is parsed. When it is determined from the parsing results that there is updated information, such as object update information or hierarchical relationship update information, the basic model will be adjusted according to the updated information to quickly respond to the dynamic changes of industrial field equipment and data sources, so that the basic model saved in the OPC UA address space unit always matches the real data in the industrial field.

[0023] S103 retrieves the basic model from the OPC UA address space unit through the knowledge graph unit and creates a knowledge graph based on the basic model.

[0024] Optionally, a knowledge graph is created based on the base model, including: extracting attribute information from each object and connecting the objects in a graph structure according to hierarchical relationships to construct an initial structure graph; and labeling the attribute information in the matching objects in the initial structure graph to obtain the knowledge graph.

[0025] Specifically, since the basic model only provides annotated, real-time data access and does not support complex relational queries and precise data acquisition, a knowledge graph supporting data queries will be further created based on the basic model to meet more comprehensive data analysis needs. The knowledge graph unit extracts attribute information from objects and connects objects with hierarchical relationships using a graph structure to obtain an initial structure graph. Each object is treated as a node in the initial structure graph, and attribute information is labeled on the matching object nodes. Then, graph database technology is used to store object nodes, hierarchical relationships, and attributes. Because the hierarchical relationships between nodes in the knowledge graph are in graphical form, it supports complex semantic queries and reasoning operations.

[0026] It should be noted that the OPC UA address space unit and the knowledge graph unit in this embodiment are dynamically and in real time associated. On the one hand, the knowledge graph unit can actively retrieve the basic model to create the knowledge graph. On the other hand, when the basic model in the OPC UA address space unit is updated, it will also generate a model update prompt. The model update prompt specifically includes the adjustment content of the basic model, such as the differences between the adjusted basic model and the original basic model. The knowledge graph unit can then update the current knowledge graph in real time according to the model update prompt, thereby ensuring that the knowledge graph and the basic model are always kept in sync.

[0027] S104 retrieves the basic model or knowledge graph based on the received business request through the unified interface service layer, generates a matching view result based on the basic model or knowledge graph, and then visualizes the view result.

[0028] Optionally, the unified interface service layer retrieves the basic model or knowledge graph based on the received business request, and generates matching view results based on the basic model or knowledge graph. This includes: identifying the type of the received business request through the unified interface service layer, where the type includes query business requests and preview access business requests; assigning the preview access business request to the OPC UA interface, and retrieving the basic model through the OPC UA interface to obtain single object information matching the preview access business request, and generating a first view result based on the single object information, where the first view result includes a details display table; assigning the query business request to the GraphQL interface, and retrieving the knowledge graph through the GraphQL interface to obtain multi-object information matching the query business request, and generating a second view result based on the multi-object information, where the second view result includes a production management view and an equipment health management view.

[0029] Optionally, the knowledge graph is retrieved via the GraphQL interface to obtain multi-object information matching the query business request, and a second view result is generated based on the multi-object information. This includes: when the query business request consists of query target objects, the knowledge graph is retrieved to obtain a first query object with a hierarchical relationship with the target object, and a production management view is generated based on the first query object and the hierarchical relationship, wherein the target object includes a factory, branch office, or work area; when the query request is to query the status of the target object, the knowledge graph is retrieved to obtain a second query object with a limited hierarchical relationship with the target object, and a device health management view is generated based on the second query object and the limited hierarchical relationship, wherein the target object includes a device or device type.

[0030] Specifically, the unified interface service layer in this embodiment includes an OPC UA interface and a GraphQL interface. The OPC UA interface is connected to the OPC UA address space unit, and the GraphQL interface is connected to the knowledge graph unit. The OPC UA and GraphQL interfaces respectively receive and process different types of business requests. The OPC UA interface receives and processes query business requests, providing standardized, real-time data access for the industrial automation field, suitable for traditional industrial clients such as SCADA, MES, and control software. The GraphQL interface receives and processes preview access business requests, providing flexible declarative queries for modern web applications, mobile applications, and data analysis platforms, supporting complex relational queries and precise data retrieval. Therefore, after receiving a business request, the unified interface service layer first identifies the type of request and assigns the request to the matching interface. For example, when a preview access request is received to "view the operating status parameters of device A", the preview request will be assigned to the OPC UA interface. The OPC UA interface will then retrieve the basic model from the connected OPC UA address space unit to obtain the detailed display table of device A, which will be used as the first view result. When a query request is received to "query the device distribution under factory X", the query request will be assigned to the GraphQL interface. The GraphQL interface will then automatically aggregate all the "device" nodes under factory X from the connected knowledge graph unit according to the production management view generation rules, starting from factory X and following the relationship path. Then, through the associated streaming computing engine, it will calculate the comprehensive output and downtime of the work area in real time, and generate a production management view based on the multi-object information. When a query request "Query the health status of type A devices" is received, the request is assigned to the GraphQL interface. The GraphQL interface then automatically filters all devices of this type from the connected knowledge graph units according to the health management view generation rules, locates key health measurement points, calculates health indicators in real time, and generates a device health management view based on multi-object information. From the above analysis, it can be seen that the OPC UA interface can only preview or view a single object; for example, the specific situation of a single device can be viewed in the form of a details table. In contrast, the GraphQL interface can view multiple objects simultaneously. For example, the health status of a certain type of device can be viewed in the form of a device health management view, or the distribution of devices in a factory can be viewed in the form of a production management view. This allows for processing different interfaces within a unified interface service layer based on different user business needs, and provides corresponding results.

[0031] In this embodiment, multiple customized data views are automatically derived and constructed based on different business needs and analytical perspectives (such as production management, quality control, and equipment health). This capability enables a single data source to simultaneously support the analytical needs of multiple business scenarios, greatly enhancing the adaptability and business value of the data model. Furthermore, this embodiment provides a unified and rich set of standardized access interfaces. Compared to existing technologies that typically only support single SQL queries, this invention supports multiple interface methods, including OPC UA information model services and graph queries. This allows the constructed data model and knowledge graph to be directly, flexibly, and efficiently integrated and invoked by various upper-layer applications, analytical tools, and control systems, completely breaking the application limitations of traditional models and achieving "model once, serve multiple places."

[0032] The technical solution of this invention automatically identifies industrial data messages and builds basic models through a data modeling engine, reducing the workload of manual configuration and coding, improving modeling efficiency, and receiving different types of business requests through a unified interface service layer. Based on the basic model and knowledge graph, it generates matching view results for personalized view display to meet different data analysis needs of users.

[0033] Example 2 Figure 3 This is a flowchart of another method for displaying data in multiple views according to an embodiment of the present invention. Based on the above embodiments, this embodiment, after visually displaying the view results, further includes receiving view adjustment instructions from the user through a visual interface, and adjusting the view results according to the view adjustment instructions to obtain the adjusted view results, such as... Figure 3 As shown, the method includes: S201 receives industrial data messages sent by various heterogeneous connectors through the data bus via the data receiving service unit, and sends the industrial data messages to the data modeling engine.

[0034] S202 constructs a basic model based on industrial data messages through a data modeling engine, and saves and maintains the basic model through OPC UA address space units.

[0035] Optionally, a basic model is constructed based on industrial data messages using a data modeling engine, including: extracting hierarchical metadata from industrial data messages using the data modeling engine, the hierarchical metadata including objects and hierarchical relationships between objects, wherein the types of objects include factories, branches, work areas, equipment and measurement points; converting each object in the OPC UA address space unit according to the OPC UA protocol to obtain the converted objects; and associating the converted objects with relationships according to the hierarchical relationships to construct the basic model.

[0036] Optionally, the basic model can be saved and maintained through the OPC UA address space unit, including: saving the basic model in a specified space location through the OPC UA address space unit; when it is determined that there is updated information based on the latest industrial data message sent by the data receiving service unit, the basic model is adjusted according to the updated information, wherein the updated information includes object update information or hierarchical relationship update information.

[0037] S203 retrieves the basic model from the OPC UA address space unit through the knowledge graph unit and creates a knowledge graph based on the basic model.

[0038] Optionally, a knowledge graph is created based on the base model, including: extracting attribute information from each object and connecting the objects in a graph structure according to hierarchical relationships to construct an initial structure graph; and labeling the attribute information in the matching objects in the initial structure graph to obtain the knowledge graph.

[0039] S204 uses a unified interface service layer to retrieve the basic model or knowledge graph based on the received business request, generates a matching view result based on the basic model or knowledge graph, and then visualizes the view result.

[0040] Optionally, the unified interface service layer retrieves the basic model or knowledge graph based on the received business request, and generates matching view results based on the basic model or knowledge graph. This includes: identifying the type of the received business request through the unified interface service layer, where the type includes query business requests and preview access business requests; assigning the preview access business request to the OPC UA interface, and retrieving the basic model through the OPC UA interface to obtain single object information matching the preview access business request, and generating a first view result based on the single object information, where the first view result includes a details display table; assigning the query business request to the GraphQL interface, and retrieving the knowledge graph through the GraphQL interface to obtain multi-object information matching the query business request, and generating a second view result based on the multi-object information, where the second view result includes a production management view and an equipment health management view.

[0041] Optionally, the knowledge graph is retrieved via the GraphQL interface to obtain multi-object information matching the query business request, and a second view result is generated based on the multi-object information. This includes: when the query business request consists of query target objects, the knowledge graph is retrieved to obtain a first query object with a hierarchical relationship with the target object, and a production management view is generated based on the first query object and the hierarchical relationship, wherein the target object includes a factory, branch office, or work area; when the query request is to query the status of the target object, the knowledge graph is retrieved to obtain a second query object with a limited hierarchical relationship with the target object, and a device health management view is generated based on the second query object and the limited hierarchical relationship, wherein the target object includes a device or device type.

[0042] S205 receives view adjustment instructions from users through a visual interface, adjusts the view results according to the view adjustment instructions, and obtains the adjusted view results.

[0043] Specifically, in this embodiment, after displaying the view results through a visual interface, the user's view adjustment commands can also be received on the visual interface to meet different data analysis needs. For example, when the production management view displays the equipment and output of each work area under factory A, upon receiving the user's adjustment command "get the work area with the highest output," the output of each tool's equipment will be summarized and added together, and the work areas will be sorted in descending order according to equipment output to obtain the work area sequence. The first work area in the sequence will be marked in the production management view. That is, this embodiment supports adding a mark to the view results. When the equipment health management view displays the values ​​of various health indicators of type A equipment, upon receiving the user's adjustment command "delete equipment with insufficient computing resources," the current resource occupancy of type A equipment will be calculated, and type A equipment with remaining resources below 30% will be filtered out and deleted in the health management view. That is, this embodiment supports deleting the view results. Of course, this embodiment is only an example. In actual applications, it also supports operations such as adding, statistical operations, and modifying connection relationships. This embodiment does not limit the specific adjustment methods. In this embodiment, by adjusting the view results, the view results can be processed again, thereby further meeting the different data analysis needs of users and improving the efficiency of data analysis.

[0044] The technical solution of this invention automatically identifies industrial data messages and builds basic models through a data modeling engine, reducing the workload of manual configuration and coding, improving modeling efficiency, and receiving different types of business requests through a unified interface service layer. Based on the basic model and knowledge graph, it generates matching view results for personalized view display to meet different data analysis needs of users.

The view result generation module 340 is used to retrieve the basic model or knowledge graph based on the received business request through the unified interface service layer, generate matching view results based on the basic model or knowledge graph, and visualize the view results.
