s40: and deriving a corresponding information model according to the model information.
It should be noted that, in this embodiment, creating an information model is implemented by using an OPC UA SDK (Software Development Kit), which follows the basic principle of OPC UA information modeling. Specifically, after the basic information of the information model is loaded into the corresponding UAServer address space, a design page of the web page is opened, and the design page includes four parts, namely a name space, the information model, details and attributes. After a user operates through a web page, acquiring user operation information through the web page, and setting the model information of an information model corresponding to basic information in the same UAServer address space according to the user operation information; the model information in the information model is set by acquiring the user operation information input by the user and responding to each user operation information to execute corresponding operation, and then the corresponding information model is derived according to the model information.

Specifically, the design page of the Web page includes four parts, namely a name space, an information model (hierarchical model structure of the information model), details and attributes. The name space is a container of the information model, namely, address information of the information model is stored, the index of the self-contained space is 0 after the OPC UA service is started, the basic type information provided by the OPC foundation, the name space with the index of 1 is used as the default of the information model, and meanwhile, a plurality of user-defined name spaces can be maintained and other constructed information models are imported into the corresponding name spaces.

The type, access level, history writing and the like of configuration data in a Variable (Variable) are all completed according to standard OPC UA specifications, and different values are provided for the Variable, and association of the Variable data with a real-time library and a historical library is realized through association measuring point operation. In actual operation, the values of the variables can be read and written by means of RESTful and standard OPC UA protocols, and variable data of the variables can also be subscribed by means of OPC UA client connection. The method has the advantages that the method is simple in process, the cost is low, and the method is convenient to use. A reference is a connection between two nodes, and the reference cannot be directly accessed and can only be indirectly accessed through a browsing node. The OPC UA specification defines a set of reference types, some of which are used in very basic places, such as the hierarchy of types, and may also define its own reference type to expose specific reference semantics. In actual operation, according to actual use requirements, objects, variables, methods and partial types are referenced, appropriate simplification is performed during web page maintenance, and an information model is conveniently and rapidly constructed.
