Abstract

The invention discloses a communication protocol configuration method and device based on OPC UA. The method comprises the following steps: collecting first data of at least one terminal device; mapping the first data into a data object in the OPC UA; adding the data object as a node into the address space of the OPC UA; forming profiles; mapping data acquired through different communication protocols to an OPC UA address space; forming a data mapping configuration file from different communication protocols to a data table structure according to the corresponding relationship. By setting theconfiguration file, flexible configuration of the whole process from different communication protocols to OPC _ UA protocol data transmission and data database storage is realized, and the efficiencyof unified acquisition, transmission, storage and analysis of various automatic equipment data at the bottom layer is improved, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an OPC UA-based communication protocol configuration method and device. Background technique [0002] The core of the OPC (Object Linking and Embedding (OLE) for Process Control) communication standard is the issue of interoperability and standardization. It is the application of Microsoft's object linking and embedding technology in process control. The traditional OPC technology solves the interoperability problem between hardware devices well at the control level, but due to the dependence on COM / DCOM technology, there are many problems in the security, cross-platform and connectivity of OPC. . In view of this, the OPC Foundation released the latest unified method of data communication - OPC Unified Architecture (OPC UA), covering different aspects of the OPC real-time data access specification, OPC historical data access specification, OPC alarm event access specifica...
