    Unmanned aerial vehicles (UAVs) are now considered one of the best remote sensing techniques for gathering data over large areas. They are now being used in the industry sector as sensing tools for proactively solving or preventing many issues, besides quantifying production and helping to make decisions. UAVs are a highly consistent technological platform for efficient and cost-effective data collection and event monitoring. The industrial Internet of things (IIoT) sends data from systems that monitor and control the physical world to data processing systems that cloud computing has shown to be important tools for meeting processing requirements. In fog computing, the IoT gateway links different objects to the internet. It can operate as a joint interface for different networks and support different communication protocols. A great deal of effort has been put into developing UAVs and multi-UAV systems. This paper introduces a smart IIoT monitoring and control system based on an unmanned aerial vehicle that uses cloud computing services and exploits fog computing as the bridge between IIoT layers. Its novelty lies in the fact that the UAV is automatically integrated into an industrial control system through an IoT gateway platform, while UAV photos are systematically and instantly computed and analyzed in the cloud. Visual supervision of the plant by drones and cloud services is integrated in real-time into the control loop of the industrial control system. As a proof of concept, the platform was used in a case study in an industrial concrete plant. The results obtained clearly illustrate the feasibility of the proposed platform in providing a reliable and efficient system for UAV remote control to improve product quality and reduce waste. For this, we studied the communication latency between the different IIoT layers in different IoT gateways.The authors would like to thank the Seneca Foundation as also FRUMECAR S.L., for their support and the opportunity to implement and test the proposed approach on their facilities.

    This article deals with the creation of a digital twin for an experimental assembly system based on a belt conveyor system and an automatized line for quality production check. The point of interest is a Bowden holder assembly from a 3D printer, which consists of a stepper motor, plastic components, and some fastener parts. The assembly was positioned in a fixture with ultra high frequency (UHF) tags and internet of things (IoT) devices for identification of status and position. The main task was parts identification and inspection, with the synchronization of all data to a digital twin model. The inspection system consisted of an industrial vision system for dimension, part presence, and errors check before and after assembly operation. A digital twin is realized as a 3D model, created in CAD design software (CDS) and imported to a Tecnomatix platform to simulate all processes. Data from the assembly system were collected by a programmable logic controller (PLC) system and were synchronized by an open platform communications (OPC) server to a digital twin model and a cloud platform (CP). Digital twins can visualize the real status of a manufacturing system as 3D simulation with real time actualization. Cloud platforms are used for data mining and knowledge representation in timeline graphs, with some alarms and automatized protocol generation. Virtual digital twins can be used for online optimization of an assembly process without the necessity to stop that is involved in a production line. © 2020 by the authors.European Union's Horizon 2020 research and innovation program under the Marie Sklodowska-CurieEuropean Union (EU) [734713]; Ministry of Industry and Trade of the Czech Republic [FV20419]; Ministry of Education of the Slovak Republic [VEGA 1/0700/20, 055TUKE-4/2020

    A building management system has user confort and comodity, as well as reduction of energy consumption, as its main goals. To accomplish this, it is necessary to integrate sensors and actuators as to control and retrieve information about the physical processes of a building. These processes include control over illumination and temperature of a room, and even access control. The information, after processed, allows a more intelligent and efficient way of controlling electronic and mechanical systems of a building, such as HVAC and illumination, while also trying to reduce energy expenditure. The emergence of IoT allowed to increment the number of low level devices on these systems, thanks to their cost reduction, increased performance and improved connectivity. To better make use of the new paradigm, it is required a modern system with multi-protocol capabilities, as well as tools for data processing and presentation. Therefore, the most relevant industrial and building automation technologies were studied, as to define a modern, IoT compatible, architecture and choose its constituting software platforms. InfluxDB, EdgeX Foundry and Node-Red were the selected technologies for the database, gateway and dashboard, respectively, as they closely align with the requirements set. This way, a demonstrator was developed in order to assess a systems’s operation, using these technologies, as well as to evaluate EdgeX’s performance for jitter and latency. From the obtained results, it was verified that, although versatile and complete, this platform underperforms for real-time applications and high reading rate workloads.Um Sistema de Gestão Centralizado tem por objetivo aumentar a comodidade e conforto dos utilizadores de um edifício, ao mesmo tempo que tenta reduzir os consumos energéticos do mesmo. Para isso, torna-se necessário integrar sensores e atuadores para controlar e recolher informação acerca dos processos físicos existentes. Nestes processos estão incluídos a iluminação e temperatura de, por exemplo, uma sala, ou até controlo de acesso. Esta informação, após processamento, permite, de uma maneira mais inteligente e eficiente, controlar os sistemas eletrónicos e mecânicos de um edifício, tais como os sistemas de AVAC ou iluminação, tentando, simultaneamente, diminuir gastos energéticos. O aparecimento do IoT, tornou possível o aumento do número de dispositivos de baixo nível nestes sistemas, graças à redução de custo e aumento de performance e conectividade que estes têm sofrido. Para melhor usufruir deste paradigma, é necessário um sistema moderno, com capacidade de conexão multi-protocolo e ferramentas para processamento e apresentação de informação. Neste sentido, fez-se um estudo das tecnologias mais relevantes da área da automação industrial e de edifícios, de modo a definir uma arquitetura moderna compatível com IoT e a escolher as plataformas de software que a constituem. InfluxDB, EdgeX Foundry e Node-Red foram as tecnologias escolhidas para a base de dados, gateway e dashboard, respetivamente, por serem as que mais se aproximaram dos requisitos definidos. Assim, foi desenvolvido um demonstrador que permitiu verificar o funcionamento de um sistema com a utilização destas tecnologias, assim como avaliar a performance da plataforma EdgeX em termos de jitter e latência. Verificou-se a partir dos resultados obtidos, que embora versátil e completa, esta plataforma ficou aquém do que se pretendia, tanto para aplicações real-time, como para as que necessitem de uma taxa de leitura de sensores elevada.Mestrado em Engenharia Eletrónica e Telecomunicaçõe

    Anturidatan lähettäminen fyysiseltä kaksoselta digitaaliselle kaksoselle

    A digital twin is a digital counterpart of a physical thing such as a machine. The term digital twin was first introduced in 2010. Thereafter, it has received an extensive amount of interest because of the numerous benefits it is expected to offer throughout the product life cycle. Currently, the concept is developed by the world’s largest companies such as Siemens. The purpose of this thesis is to examine which application layer protocols and communication technologies are the most suitable for the sensor data transmission from a physical twin to a digital twin. In addition, a platform enabling this data transmission is developed. As the concept of a digital twin is relatively new, a comprehensive literature view on the definition of a digital twin in scientific literature is presented. It has been found that the vision of a digital twin has evolved from the concepts of ‘intelligent products’ presented at the beginning of the 2000s. The most widely adopted definition states that a digital twin accurately mirrors the current state of its corresponding twin. However, the definition of a digital twin is not yet standardized and varies in different fields. Based on the literature review, the communication needs of a digital twin are derived. Thereafter, the suitability of HTTP, MQTT, CoAP, XMPP, AMQP, DDS, and OPC UA for sensor data transmission are examined through a literature review. In addition, a review of 4G, 5G, NB-IoT, LoRa, Sigfox, Bluetooth, Wi-Fi, Z-Wave, ZigBee, and WirelessHART is presented. A platform for the management of the sensors is developed. The platform narrows the gap between the concept and realization of a digital twin by enabling sensor data transmission. The platform allows easy addition of sensors to a physical twin and provides an interface for their configuration remotely over the Internet. It supports multiple sensor types and application protocols and offers both web user iterface and REST API.Digitaalinen kaksonen on fyysisen tuotteen digitaalinen vastinkappale, joka sisältää tiedon sen nykyisestä tilasta. Digitaalisen kaksosen käsite otettiin ensimmäisen kerran käyttöön vuonna 2010. Sen jälkeen digitaalinen kaksonen on saanut paljon huomiota, ja sitä ovat lähteneet kehittämään maailman suurimmat yritykset, kuten Siemens. Tämän työn tarkoituksena tutkia, mitkä sovelluskerroksen protokollat ja langattomat verkot soveltuvat parhaiten anturien keräämän datan lähettämiseen fyysiseltä kaksoselta digitaaliselle kaksoselle. Sen lisäksi työssä esitellään alusta, joka mahdollistaa tämän tiedonsiirron. Digitaalisen kaksosesta esitetään laaja kirjallisuuskatsaus, joka luo pohjan työn myöhemmille osioille. Digitaalisen kaksosen konsepti pohjautuu 2000-luvun alussa esiteltyihin ajatuksiin ”älykkäistä tuotteista”. Yleisimmän käytössä olevan määritelmän mukaan digitaalinen kaksonen heijastaa sen fyysisen vastinparin tämän hetkistä tilaa. Määritelmä kuitenkin vaihtelee eri alojen välillä eikä se ole vielä vakiintunut tieteellisessä kirjallisuudessa. Kirjallisuuskatsauksen avulla johdetaan digitaalisen kaksosen kommunikaatiotarpeet. Sen jälkeen arvioidaan seuraavien sovelluskerroksen protokollien soveltuvuutta anturidatan lähettämiseen kirjallisuuskatsauksen avulla: HTTP, MQTT, CoAP, XMPP, AMQP, DDS ja OPC UA. Myös seuraavien langattomien verkkojen soveltuvuutta tiedonsiirtoon tutkitaan: 4G, 5G, NB-IoT, LoRaWAN, Sigfox, Bluetooth, Wi-Fi, Z-Wave, ZigBee ja WirelessHART. Osana työtä kehitettiin myös ohjelmistoalusta, joka mahdollistaa anturien hallinnan etänä Internetin välityksellä. Alusta on pieni askel kohti digitaalisen kaksosen käytän-nön toteutusta, sillä se mahdollistaa tiedon keräämisen fyysisestä vastinkappaleesta. Sen avulla sensorien lisääminen fyysiseen kaksoseen on helppoa, ja se tukee sekä useita sensorityyppejä että sovelluskerroksen protokollia. Alusta tukee REST API –rajapintaa ja sisältää web-käyttöliittymän
