IIoT based platform for Industry 4.0 [Project website]
In this project, we are designing and implementing an IIoT platform for training students in industry 4.0 technologies. The platform will integrate a central server with controlled process modules using portable, compact, and low-cost modules operated remotely by the students. At the end of the project, a training program will be offered in conjunction with strategic Colombian industries.
Collaborators: Diseño y Automatización Industrial S.A.S. (Colombia).
This project is supported by MinCiencias "Diseño, desarrollo e implementación de una plataforma IIoT para formación de profesionales en tecnologías de la cuarta revolución industrial".

In Industry 4.0, connected systems must reliably exchange data across operational and enterprise levels. This paper compares two UNS architectures: the Schultz method, which distributes data across multiple MQTT brokers, and the Parris method, which centralizes everything in a single broker. After evaluating both under the same realistic industrial conditions, we found that the Parris method processes messages faster, while the Schultz method uses resources more efficiently and is more resilient to failures.

Unified Namespace (UNS)-based architectures offer a powerful solution by enabling seamless, real-time data integration and scalable interoperability across systems. This paper presents the key concepts and design methods for UNS implementation in manufacturing. A case study illustrates how a UNS enhances data integration and operational efficiency in real-world environments.

This paper presents the design and implementation of an IIoT-based monitoring system for the CASIRI radio astronomy station, a mobile platform used to characterize potential sites for radio observatories in Colombia and Antarctica. The proposed system is integrated into a broader IIoT platform designed to support both operational monitoring and educational activities. Its performance and component interoperability were validated through a series of experimental tests under simulated conditions.

This work presents the design, implementation, and validation of an IoT system for an experimental laboratory microgrid developed at Universidad Industrial de Santander. The main design phases of the IoT system are described, beginning with the definition of requirements and extending through the component selection. Validation tests are proposed to verify the functionalities of the IoT system.
