Address space management method and device, equipment and medium

Abstract

The invention discloses an address space management method and device, equipment and a medium, and the method comprises the steps that a connection between a client and a server is obtained, and the information model data of an address space from the server is obtained; and the client responds to a query instruction input by a user, obtains target information model data from the information modeldata, converts the target information model data into a corresponding force guide graph, and displays the force guide graph on the user interface. When a user modifies the force guide graph on the user interface, the client can obtain operation data of the user, transmit the operation data to the server to update the address space, receive an update result of the address space and update the forceguide graph. According to the method, visualization of all structures of the address space of the server can be achieved, the reference relation between all nodes of the address space can be expressed, the force guide graph can be dynamically edited, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of address space management, in particular to an address space management method, device, equipment and medium. Background technique [0002] OPC UA is a very important C / S architecture industrial IoT communication protocol. Compared with other protocols, its biggest feature is that it can provide a semantic information model. The International OPC Foundation has defined hundreds of service interface specifications (OPC UASERVICE) between the server and the client, which are used by the client to read, write, add, delete, modify and query the server information model. The OPC UA information model is organized in a node network in the server. Nodes are divided into eight types: objects, object types, variables, variable types, methods, reference types, data types, and views. Connections, the network of nodes is also called the "address space". Users need corresponding tools and methods to add, delete, modify...

AI Technical Summary

Problems solved by technology

[0003] At present, the most widely used method is to display the address space of the connected server in the form of a tree diagram, and to realize functions such as browsing, reading and writing, and method calling through right-click operations in the user interface interface, but the structure of the address space cannot be changed.

And there are complex reference relationships between nodes in the OPC UA address space, but the dendrogram can only display nodes, not the reference relationship
