Wireless Sensing Based on RFID and Capacitive Technologies for Safety in Marble Industry Process Control
Source: University of Pisa
This paper presents wireless sensing systems to increase the safety and robustness in industrial process control, particularly in industrial machines for marble slab working. The experimented contact-less sensing systems are based on RFID and capacitive technologies. Their application has the final aim of detecting the presence of a marble slab to be worked by the marble machine, at the machine entrance stage and in proximity of the working tools inside the machine. The proposed techniques aim at overcoming some limitations of the currently used slab detection systems, consisting in electromechanical or optical devices, suffering from deterioration and from the dirty and wet working environment.
