Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

Example

FIG. 1 is a block diagram of a unified modeling platform for an industrial app according to an embodiment of the present application.

As shown in FIG. 1 , the unified modeling platform provided in this embodiment is applied to an electronic device. The electronic device can be understood as a computer or server with data computing and information processing. The unified modeling platform includes a built-in plug-in module 10 and a system. Kernel 20. Wherein, the system kernel of the present application includes a meta-model bootstrapping module 21, a model data operation protocol module 22, a model data publishing module 23 and a model data processing plug-in module 24.

The meta-model bootstrapping module is the foundation of the entire platform, and this module is used to complete the self-description of the meta-model, so that it does not need to depend on any other modules. A metamodel is a model about a model, for example in the field of data modeling, a metamodel is a model that describes a data table. A set of modeling elements and rules for using these elements can be provided and applied recursively to describe business models and meta-models in a unified way.

The metamodel provides two concepts, the logical table metamodel and the logical field metamodel. Among them, the logical table meta-model is used to describe the model body; the logical field meta-model is used to describe the model structure, and the model bootstrapping is completed through the following three logical tables.

a. Logical table metamodel:

name description logic_table logical table metamodel logic_column Logical Field Metamodel logic_data_type Logical Data Type Metamodel

b. Logical Field Metamodel:

logic_table name logic_data_type description logic_table name string logical table name logic_table description string Logic table description logic_column name string logical field name logic_column description string logical field description logic_column data_type string logical type logic_data_type name string logical type name logic_data_type description string logical type description physical_data_type name string physical type name physical_data_type description string Physical Type Description

c. The logical data type of the metamodel:

The model data operation protocol module is used to define the standard rest interface of data addition, modification and deletion, and batch mixing operations. The data is transmitted in json format. The logical table in the interface route is used as a resource. The platform implements a data operation protocol, through which all data operations must be completed, and no other methods are provided.

The model data publishing module is used to publish the entire operation as a message after the platform has processed the data operation; it provides two methods, asynchronous and synchronous, for external monitoring of the message. The synchronous method needs to wait for the other party to process the message and confirm it before completing. The asynchronous operation does not block the current data operation. In order to ensure the stability of the platform, all external modules that need to be processed synchronously must meet the performance requirements.

The model data processing plug-in module provides a set of plug-in system, which is built on the model data publishing module, and provides a series of functions such as plug-in registration, logout, and running performance monitoring. At the same time, the module also manages plug-in models with unified modeling capabilities.

The system kernel provides platform-independent capabilities, but as an industrial app development platform, a set of platform standards needs to be defined. However, all the capabilities related to the platform are completed through plug-ins, which greatly improves the universality and extensibility of the platform. Correspondingly, the system built-in plug-in module in this application is used to provide plug-in services according to the user's plug-in configuration request, which specifically includes but is not limited to platform metadata plug-ins, data persistence plug-ins, object model extension plug-ins, and time series data modeling plug-ins.

Platform metadata plugins are used to define metadata about the platform itself, such as the version of the platform, the modules it contains. All APIs provided by the system and all apps installed by the platform.

The data persistence plugin is used to persist model data to various databases, so that the entire platform is decoupled from the specific database, and the same data can even be persisted to different databases, such as relational databases and graph databases. This plug-in mechanism greatly improves the flexibility and universality of the system.

The object model extension plug-in is used to describe the entities and the relationships between entities more abundantly in the modeling process of the object model. For example, the platform can extend the meta model to provide meta models such as events and services, and provide the The ability to define metadata such as attributes on the data. This is a typical example of increasing platform capabilities by extending the metamodel.

Time series data has many unique features. For example, each time series data is a data stream, and by extending the attribute meta model, the time series data modeling plug-in can add more metadata information for time series attributes, such as the unit of the attribute, the underlying layer. sensor information, etc. By extending the metamodel, rather than solidifying this capability into the system kernel, time series data modeling and relational data modeling can be integrated to provide a set of standard concepts and tools, and at the same time, time series data and relational data can be connected to each other to establish Relationships and mutual perception provide apps with richer data processing capabilities.

It can be seen from the above technical solutions that this embodiment provides a unified modeling platform for industrial apps, including a system kernel and a built-in plug-in module of the system. The system kernel includes a meta-model bootstrapping module, a model data manipulation protocol module, a model data publishing module and a model data processing plug-in module; the meta-model bootstrapping module is used to implement the self-description of the model; the model data manipulation protocol module is used to provide new data Add, modify or delete services, and also provide standard rest interface services; model data publishing module is used to publish data operations as messages after completing data operations; model data processing plug-in modules are used to provide plug-in registration, logout and running Performance monitoring service; the built-in plug-in module of the system is used to provide plug-in services according to the user's plug-in configuration request. This solution allows industrial app developers to easily perform relational data modeling and object model modeling, and integrate all factory data by building the relationship between these data.

By integrating all data, the development efficiency of developers is improved, duplication of work is avoided, and learning costs are reduced. Make it easier for developers to model the data of the entire factory, and efficiently extract, precipitate, and abstract industrial knowledge.

Since the platform unifies data and metadata, app developers no longer need to call various metadata creation interfaces to create models, but only need to care about data operation protocols. This not only reduces the complexity of app development, but also improves the scalability of the model.

This platform packs the cement industry standard model into the app, and can complete the creation of the cement industry standard model by installing the app in the implementation stage.

The app developers of a cement group conduct customized development based on the general cement industry standard model to meet the special needs of the group.

In the unified modeling platform, a plug-in can be developed. The plug-in first adds a row of data in the data type meta model: name: repo_number, description: warehouse order number type. Then, the published data operation message is processed, and the corresponding field whose data type is repo_number is filled with the generated warehouse code. Through this extension plug-in, all app developers can use this extended data type directly without caring about the warehouse order number generation logic to improve the efficiency of app development. If combined with the visual app configuration platform, integrating this data type directly into the configuration can make low-code development more efficient.

In a specific cement plant under the cement group, the on-site engineering implementers can continue to carry out customized development based on the model customized by the group to deal with the special needs of the cement plant, such as adding some fields to the warehouse model, in the unified modeling In the platform, you can directly add fields to the logical field model through the data operation protocol.
