Abstract

The invention discloses a method for implementing an OPC UA data interface of an industrial real-time database, which includes configuring OPC UA equipment and storing real-time data. The invention has the advantages that: the data interface of the OPC UA of the industrial real-time database can be opened, and the real-time data of the OPC UA device and the platform software can be read and stored; the invention provides the record addition and / or modification of the database in the equipment configuration process, which effectively guarantees the applicability of all OPC UA equipment. The invention integrates the API provided by the official OPC Foundation in the real-time database and realizes the connection of the OPC UA device and the data reading and storing in the real-time databasewithout other application programs. The configuration information in the invention is stored in a relational database, and the real-time data is stored in the real-time database, so that the storage of the high-frequency real-time data of the OPC UA is realized, and the operability is strong.

Description

technical field [0001] The invention relates to the technical field of wireless network monitoring, in particular to a method for realizing an OPC UA data interface of an industrial real-time database. Background technique [0002] With the increasing complexity of industrial process systems, in order to ensure their safe and stable operation, industrial real-time database systems have been more and more widely used in industrial process monitoring, and have gradually become an indispensable technology for advanced control, process detection and plant-level information management. data platform. [0003] As one of the commonly used transmission protocols in industrial sites, OPC is an interoperability standard for data security exchange in the automation industry and other industries, and is widely used in many fields. It is platform independent and ensures seamless transfer of information between devices from multiple vendors. With the introduction of a service-oriented a...
