An IoT smart system to ensure safety in industrial working environments through a 2.4 Ghz radio controllable interface

One third of humans' life is spent at work, therefore, the last decades have seen an increasing interest of companies in guaranteeing safety and security to employees in their plants, offices and industries. One of the paradigms that has mostly contributed to the transformation of the interest into real interventions is the Internet of Things that, thanks to its multitude of connected devices have enhanced various daily employees' routines and activities. Although different solutions have already been proposed to this aim they are usually focused on verifying the operation of the entire industrial plant without any specific attention to the respect of “micro”-measures, like the closure of a gate. In this paper we propose a modular architecture, designed within the SENERGY Project, with the aim of supporting the energizing and de-energizing of a set of industrial machines and guaranteeing, at the same time, the safety of workers in their maintenance duties. Specifically, the paper is focused on the exploitation of a remote device controllable through a 2.4 Ghz radio interface to both monitor the respect of specific safety measures and promptly intervene in case of necessity. A prototype is implemented through a commercial fast-prototyping device used to demonstrate the feasibility of the proposed solution and open up to future works.
