Description

Data collection device and method for manufacturing equipment using OPC UA {APPARATUS FOR COLLECTING DATA OF MANUFACTURING FACILITY USING OPC UA}

The present invention relates to a data collection device and method for manufacturing equipment using OPC UA. More specifically, the present invention relates to a data collection device and method for collecting data from various types of manufacturing equipment using OPC UA by providing standardized data by storing it in a database in an integrated manner. , It relates to a data collection device and method for manufacturing facilities using OPC UA, which allows various solutions to be provided based on data commonly stored in various upper solutions.

Entering the 21st century, the number of skilled workers has gradually decreased due to population aging, and as technological trends have changed, the life cycle of manufactured products has drastically shortened.

In addition, as consumer needs become more diverse, personalized production is required, and the economic structure is shifting from manufacturing to the service industry, including information technology. As existing manufacturing companies are suffering large losses, innovation in the manufacturing industry is required.

Today's IoT (Internet of Things) technology is attracting attention as a core technology for a hyper-connected society that connects and interacts with all objects, spaces, and environments in the real world through a network. In the manufacturing sector, there is also an increasing number of cases of introducing smart factories that realize more intelligent production automation by applying IoT technology to the production process.

In a smart factory, all facilities and devices are connected by communication, allowing data to be freely linked between processes, thereby creating a more integrated and optimal production environment.

As smart factories are implemented in this way, by having a data-based production line that analyzes and makes decisions based on numerous data collected from each factory, it is possible to obtain correlations between phenomena and problems that occur at the production site. Unknown causes of unexpected failures and poor quality can now be resolved through data analysis.

These data are linked to the time system in the production and management fields through solutions such as MES (Manufacturing Execution System), VR (Virtual Reality), AR (Augmented Reality), Digital Twin, Big Data, and AI (Artificial Intelligence). Once this is received or a management decision is made on which optimal production system to operate, the production line can respond flexibly.

Meanwhile, OPC UA (Open Platform Communications Unified Architecture) is a platform-independent industrial data communication standard that enables data integration and exchange without being dependent on heterogeneous industrial devices, systems, and application services. It is not only independent in terms of software, but also It can provide an environment that can configure an independent platform for hardware, and basically has a client and server structure.
