Sommario
Scopo del presente lavoro è quello di presentare un sistema automatico brevettato di gestione e monitoraggio da remoto dei materiali e delle strutture edilizie, siano esse interrate o elevate, verificandone costantemente ed in tempo reale le condizioni di integrità, nel rispetto e salvaguardia dell’ambiente. Il metodo di verifica prevede l’utilizzo di sensori a base di nanotubi di carbonio (CNT) e la misura di conducibilità. L’implementazione di alert programmabili e gestibili da una piattaforma remota consente l’amministrazione della rete monitorata in tempo reale, grazie ad una interfaccia uomo-macchina (HMI), massimizzando la sicurezza, evitando l’operato umano ed offrendo la possibilità di cooperazione con dispositivi IoT con medesime finalità.

Title
AUTOMATIC SYSTEMS AND SENSORS BASED ON CARBON NANOTUBES (CNT) FOR REMOTE MONITORING OF STRUCTURES AND BUILDING MATERIALS
Abstract
The aim to this invention is to show an innovative patented device and consistent method for the constant, real-time and remote check of structures and building materials. The embedded system projected to this scope is prepared for the conductivity measurement in order to check, through this parameter, the uniformity state of the structure or material. The method provide to use a sensors composed of carbon nanotubes (CNT), a nano-material know to have a very high conductivity capability. With a perfect mix of this nano-material with cement compounds is possible to create a natural sensor IoT oriented. The ALERT implementation through an HMI interface capable to send a signal when a mistake occurs allows to prevent structures decay. As a matter of a fact the ALERT is based on a set of security threshold. Furthermore the device works autonomously. So is not necessary the intervention of a human resource because it is controlled and managed from remote, through an interface manageable from a desktop or simply a mobile device. The device is composed of an electronic circuit in which the measurement circuit separated from the alimentation circuit. So there is a voltmetric probe, for the measurement and an amperoetric probe, to inject the electric signal to the structure or material. Because of the smallness of the wanted signal, the circuit provide the use of a set of amps arranged in cascade, in order to find an accurate measurement. When the conductivity value exceeds the threshold and ALERT send a notification to the IoT device associated to the instrument. So it is possible to attend if there is some warning before it’s too late, minimizing the danger and maximizing the security.
