- Ajuste dinâmico e automático de iluminação em sistemas industriais e edifícios usando tecnologias de IoTPublication . Silva, Carolina Miller da; Leitão, Paulo; Barbosa, José; Faletti, LucianaA crescente busca por sistemas sustentáveis e de baixo impacto ambiental tem movimentado pesquisas em diversos setores, buscando uma maior eficiência energética e uma atenuação destes impactos, levando-se em conta que os gastos energéticos nesses setores contribuem significativamente com o consumo mundial e com as emissões de gases de efeito estufa. Devido ao alto consumo energético atrelado a edifícios, sendo eles residenciais, comerciais, ou industriais, um dos setores de interesse dessas pesquisas é a área de Automação Residencial, já que esta apresenta sistemas capazes de aprimorar a eficiência energética e aumentar o conforto de seus habitantes. Também por interesses em conforto e acessibilidade, a Internet das Coisas está cada vez mais em evidência, o que pode ser visto com a quantidade de dispositivos conectados a rede, que já ultrapassa a população mundial e não há indicações de que vá parar de crescer. Essa tecnologia vem sendo aplicada em diversas áreas, incluindo a domótica, onde é usada para facilmente resolver problemas de interconexão de dispositivos atrelados a ela. Diante disso, o foco desse projeto é o desenvolvimento de um sistema domótico, para áreas tanto residenciais, quanto industriais, utilizando tecnologias IoT para um controle remoto do sistema. O sistema busca aumentar o conforto de seus usuários, enquanto reduz o consumo energético e se preocupa com a segurança, utilizando para isso a gestão da iluminação do ambiente.
- Low cost integration of IoT technologies for building automationPublication . Morenas, Javier de las; Silva, Carolina Miller da; Barbosa, José; Leitão, PauloInternet of Things (IoT) envisages a reality in which people and objects are interconnected in such a way that a series of services, previously unthinkable, become real. The impact of IoT technologies is already tangible in industry, particularly under the Industry 4.0 initiative, but yet far to be fully exploited in other areas, such as building automation. This paper highlights the importance of using IoT and other emergent technologies to develop building automation applications that serves as base in smart cities, particularly supporting the interoperability among home automation solutions provided by different manufacturers. For this purpose, a low cost IoT enabler solution for building automation is presented, based on the use of cyber-physical systems, as backbone to integrate different IoT technologies and building automation technologies. The proposed approach was successfully implemented in an open space laboratory.
- Security experiences in IoT based applications for building and factory automationPublication . Morenas, Javier de las; Silva, Carolina Miller da; Funchal, Gustavo Silva; Melo, Victória; Vallim, Marcos; Leitão, PauloIndustry 4.0 and Industrial Internet of Things (IIoT) are promoting the connection of millions of devices, that once were seen as unconnectable, into a huge network, to be used in a large number of applications, from autonomous vehicles to industrial control systems, passing through building automation systems. These paradigm rely on the adoption of Cyber Physical Systems complemented with Internet of Things (IoT) technologies and artificial intelligence techniques. These type of systems are responsible for collecting, processing and exchanging a vast amount of data, and for that reason, it is imperative to assure data integrity and protection against malicious modifications and attacks to ensure a safe and reliable operation. Data thefts and cyber attacks in general represent a significant danger, however, cyber attacks on IoT systems can be specially critical due to their proximity with humans, enhancing the risk of physical damage. This paper highlights the importance of securing these systems, pursuing a safer operation, having in mind the amount of security vulnerabilities found in embedded devices. For this purpose, this article studies possible security threats and weakness in two case studies coming from different IoT domains, i.e. building automation and factory automation, while seeking for solutions to improve these systems’ security.
