Problems solved by technology
[0003] At present, many OPC UA services released by the International OPC UA Foundation do not provide a method to directly export the information model in the server from the OPC UA client. The client can only browse the address space of the server, browse the structure of an object, and then Manually creating its type in the application and instantiating it requires a lot of manpower and time

The invention discloses a method, device and system for transmitting an information model and a medium. The method comprises the steps of receiving node identification data of an object sent by a client, querying object data corresponding to the node identification data of the object in an address space, constructing an information model based on the object data, packaging the information model toobtain a first package, sending a first analysis instruction to the client, and sending the first parsing instruction to the client, so that the client responds to the first parsing instruction to execute parsing operation, and performing analysis processing on the first package based on the analysis operation, and the information model is reconstructed based on the analyzed data, and the first analysis instruction comprises the first package and an instruction for analyzing the first package. Thus, the problems of difficult interaction and low transmission efficiency of the information modelbetween a client and a server are solved.
Description
technical field [0001] The present invention relates to the technical field of Internet communication, in particular to a method, device, system and medium for transmitting information models. Background technique [0002] OPC UA is a C / S architecture interconnection protocol that meets the requirements of Industry 4.0. Its address space and information model are important technologies that support CPS cyber-physical systems and digital twins. The objects and related information provided by the OPC UA server to the client are related to the address space of the server, and the basic unit of the address space is a node. A node is mainly composed of attributes and references of the node. Attributes are used to describe nodes, which determine the characteristics of nodes. The 8 nodes of OPC UA are objects, object types, variables, variable types, methods, reference types, views, and data types. Attributes describe the node itself, and references define relationships to other...
