RT Journal Article T1 Battery-Less Industrial Wireless Monitoring and Control System for Improved Operational Efficiency A1 Hidalgo Fort, Eduardo A1 Gómez Galán, Juan Antonio A1 González Carvajal, Ramón A1 Sánchez Cárdenas, Pedro A1 Clemente Maya, Carlos AB An industrial wireless monitoring and control system, capable of supporting energyharvestingdevices through smart sensing and network management, designed for improving electrorefineryperformance by applying predictive maintenance, is presented. The system is self-poweredfrom bus bars, and features wireless communication and easy-to-access information and alarms. Withcell voltage and electrolyte temperature measurements, the system enables real-time cell performancediscovery and early reaction to critical production or quality disturbances such as short-circuiting,flow blockages, or electrolyte temperature excursions. Field validation shows an increase in operationalperformance of 30% (reaching 97%) in the detection of short circuits, which, thanks to a neuralnetwork deployed, are detected, on average, 10.5 h earlier compared to the traditional methodology.The developed system is a sustainable IoT solution, being easy to maintain after its deployment, andproviding benefits of improved control and operation, increased current efficiency, and decreasedmaintenance costs.
