Abstract

The invention discloses a method for realizing an OPC UA data interface of an industrial real-time database, which includes two parts: OPC UA device configuration and real-time data storage. Its beneficial effects are: the present invention opens up the OPC UA data interface of industrial real-time database, can realize the reading and storage of real-time data supporting OPC UA equipment and platform software; or modification, effectively guaranteeing the applicability of all OPC UA devices; the present invention integrates the official API provided by the OPC Foundation in the real-time database, without other application programs, and realizes the connection and data reading and storage of OPC UA devices in the real-time database; The middle configuration information is stored in the relational database, and the real-time data is stored in the real-time database, which realizes the storage of high-frequency real-time data of OPC UA, and has strong operability.

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...
