[0032] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0033] Example 1

[0034] like Figure 1 As shown, a structural block diagram of a unified control system supporting multiple industrial control protocols provided by the first embodiment of the present invention is shown, the system includes: a protocol parser module, a data management module, a UI interface module and a protocol control module, the protocol parser module uses a protocol parser to parse, abstract and encapsulate various industrial control protocols, and sends the encapsulated data to the data management module for processing, the data management module is used to store, process and control the received data and the data interaction with the UI interface module, the UI interface module is used to split the UI interface into multiple reusable components, customize the position of the components on the canvas, configure the protocol wizard and automatically load the corresponding protocol parser, the protocol control module is used to control the start and stop of the master station, system configuration and the reading and writing operations of process data.

[0035] Each protocol parser module is responsible for parsing, abstracting and encapsulating one or a class of industrial control protocols, and supports the import of device description files of various protocols, such as Profinet's GSDML file, EtherCAT's ESI file, EtherNET / IP's EDS file, etc., and can be displayed in the system's device library, such as Figure 2 As shown. The protocol parser module includes a verification unit, which is used to verify the imported device description file. If it is incorrect, it prompts that the device description file is imported incorrectly. If it is correct, the protocol type is obtained and the protocol type is sent to the protocol parsing unit for processing. The protocol parser module includes a protocol parsing unit, which is used to call the corresponding protocol parser according to the protocol type to parse and obtain the original data of the protocol. The protocol parser module also includes a protocol abstraction unit, which is used to classify the original data of different protocols according to protocol-slave-module-submodule to realize a unified protocol abstract interface. The protocol parser module also includes a protocol encapsulation unit, which is used to encapsulate protocol data and provide the encapsulated data to the data management module for processing. The protocol parser module also supports dynamic loading and unloading of the protocol parser, which is convenient for users to flexibly configure according to actual needs.

[0036] The data management module uses SQLite database to realize data storage, data processing and data interaction functions. The data management module includes data storage unit, data processing unit and data interaction unit. The data storage unit uses B-tree index, supports ACID transactions, and provides efficient data organization and security. The data processing unit provides data processing and analysis functions, such as data filtering, aggregation, alarm, etc. It has a built-in query optimizer, supports user-defined functions and triggers, and optimizes query performance and data processing logic. The data interaction unit is used to interact with the UI interface module to realize real-time display and feedback of data. In addition, it also provides a multi-language interface, supports lightweight embedded deployment, and can achieve network synchronization through middleware.

[0037] The UI interface module includes componentized design unit, responsive layout unit, graphical configuration unit and configuration wizard unit. The componentized design unit is based on the componentization concept of Vue3, splits the UI interface into multiple reusable components, and implements a drag-and-drop component configuration tool. Users can drag different components (such as dashboards, trend charts, tables, etc.) to the canvas and bind data sources to display real-time data. The responsive layout unit supports multiple screen sizes and resolutions to ensure a good user experience on different devices. The graphical configuration unit provides a graphical configuration tool, and users can easily complete the configuration by dragging, clicking, etc. The configuration wizard unit is used to add a protocol configuration wizard to guide users to select the protocols that need to be supported and automatically load the corresponding protocol parser.

[0038] The protocol control module includes the master control unit, the system configuration unit and the process data interaction unit; the master control unit is used to control the start and stop status of the master. The system configuration unit supports system configuration, adding system topology, changing device configuration parameters and other operations. The process data interaction unit is used to obtain process data and read and write process data.

[0039] like Figure 3 As shown in the figure, the implementation of building the Profinet system topology diagram is shown. The specific implementation steps are as follows:

[0040] 1. Add PLC device DU03 to the project;

[0041] 2. Add ProfiNet bus to DU03 PLC;

[0042] 3. Add DN8032 and ET200sp slaves under ProfiNet bus;

[0043] 4. DU03, DN8032 and ET200sp devices appear in the topology diagram;

[0044] 5. According to the preset topology, connect the network interfaces of each device to realize the system topology diagram.

[0045] The embodiment of the present invention provides a unified control system that supports multiple industrial control protocols. The various industrial control protocols are abstracted into a unified interface through a protocol parser module, making the integration of new protocols simple and fast. A modular architecture is adopted to divide the configuration software into multiple independent modules, each of which is responsible for a specific function. The modules communicate through well-defined interfaces, which reduces the coupling between modules and improves the maintainability and scalability of the system. By adopting dynamic loading technology, users can load or unload protocol parsers as needed during runtime, which not only improves the flexibility of the software, but also reduces the waste of system resources.

[0046] The beneficial effects of a unified control system supporting multiple industrial control protocols provided by an embodiment of the present invention are as follows:

[0047] 1. Significantly improve interoperability: By supporting multiple industrial control protocols, the application scope of configuration software is expanded to meet the needs of different industrial scenarios.

[0048] 2. Significantly reduce development costs: The use of modular design and protocol abstraction layer technology reduces development difficulty and cost and accelerates the product development cycle.
