Desarrollo de una arquitectura IIOT de adquisición y procesamiento de datos para el monitoreo y control de variables físicas empleadas en un proceso de producción

Abstract

The integration of Industrial Internet of Things (IIoT) technology enables the transformation of industrial environments through intelligent monitoring, continuous connectivity, and decentralized analysis. This study presents the design and implementation of an IIoT architecture for real-time temperature monitoring and control in a storage area for flammable raw materials. The system uses an Ex-rated temperature sensor, a Siemens S7-1200 PLC, and a SIMATIC IoT2040 gateway. It incorporates edge computing and secure MQTT communication with the Insight Hub cloud platform. A critical temperature threshold of 30°C was established, given the explosion risk posed by hydrogen peroxide at this level. To address this, a Telegram-based notification system was developed to provide immediate alerts and remote status access. The integrated dashboard displayed latency between 250 ms and 1 s; during real operating conditions, total system latency was measured at 1 second, which proved suitable for operational needs. The results validate the proposed architecture, meeting the interoperability, scalability, and cybersecurity requirements of Industry 4.0.
