- KNOWLEDGE-DRIVEN PRODUCTION LINES: SCALABLE SYSTEM FOR REAL -TIME MACHINE MONITORING AND CONTROLLING IN INDUSTRIAL ENVIRONMENTSPublication . Francisco, Diogo Jesus Gomes; Rodrigues, Nuno Carlos Sousa; Gonçalves, Alexandrino José Marques; Ribeiro, Roberto Aguiar; Marto, Anabela Gonçalves RodriguesToday, the industrial sector is already in the Industrial Revolution 5.0. However, some enterprises have not reached the fourth industrial revolution either because they don’t know the potential of the technologies involved or because they don’t have the monetary resources needed to integrate them into the manufacturing processes. One of the affected sectors by this lack of digitization is the stone industrial sector. These enterprises contain heavy machines within big warehouses, which work stones through robotic arms that move on several axes with cutting and milling tools to elaborate them and create several products, such as kitchen worktops and decorative pieces. Thus, a solution was developed to help these enterprises adapt and evolve. The present solution was initially conceptualized for the stone ornamental industry sector, but it can be the basis for other future solutions in this branch. The current developed solution integrates the OPC UA protocol as it is considered an industrial standard and has recently been incorporated into industrial machines, which promotes longevity for this solution. In terms of features, the developed system enables the industrial stakeholders in a factory to remotely visualize the parameters of the existing machines on the factory shop floor, as well as to modify their state from a Web application, increasing the operators’ awareness and control over the manufacturing process. At the level of new machine integration into the developed system is possible to make it in a simple way and without advanced technical knowledge, which guarantees the independence of companies in the process. In addition, this solution took into account the concept of DT, which consists of having digital representations of one or more physical entities, such as industrial machines, where they are fully synchronized with each counterpart. These representations are made through a dynamic web platform, which adapts to each machine integrated into the system. Last but not least, the solution was tested at the level of transmission data latency, the usability of the web application, and coverage of several physical entities, which simulated a production line. As a result, the system has demonstrated the ability to keep operators and engineers synchronized on production lines remotely, as well as demonstrating the ability to offer versatility in terms of dynamically incorporating different machines without a great amount of knowledge and effort by the users.
