Ítem Desarrollo de un transductor de torque de bajo costo, utilizando galgas extensiométricas y protocolos de comunicación del internet de las cosas(Universidad EAFIT, 2020) Correa Hernández, Abraham Andrés; Botero Herrera, Francisco JavierThe objective of this project was to develop a low-cost torque transducer that had the ability to send data in real time to multiple devices by applying Internet of Things communication protocols. To begging with the development, it was first necessary to collect bibliographic information to be aware of similar developments, the second step to follow was to define the operating parameters under which the prototype would be designed. Once the design parameters were defined, the quantitative comparison of the different low-cost microcontrollers was carried out to determine which is the most appropriate, with this step concluded, the conceptual design was carried out using the CAD tool of the different components of the transducer. With the preliminary designs completed, we proceeded to carry out the solution of the mathematical models that describe the behavior of the torque and at the same time the finite element simulation of the transducer was performed. The results obtained from the mathematical models and the simulation results were compared to determine if the simulation describes the effects suffered by the material. Once the stress analysis of the transducer was completed, the process of generating the manufacturing drawings began, and at the same time the process of developing the communication interfaces began using the Internet of Things communication protocol. It was concluded that the microcontroller that is most appropriated to the needs is the RASPBERRY PI ZERO W, because it does not require an externals module for establishing remote connections. Mathematical models and finite element simulations showed that the 6061 T6 aluminum alloy is capable of withstanding the proposed working conditions and it was possible to establish data communication between the RASPBERRY and a computer using an interface in LABVIEW using the TCP / IP communication protocol.Ítem Estudio de factibilidad para la comercialización de una aplicación que monitoree la salud de los niños en el Valle de Aburrá.(Universidad EAFIT, 2019) Morales Sánchez, John Alejandro; Tobar Guinand, José MauricioThe development of the internet has allowed the emergence of the Internet of Things, where common objects have been able to connect to the network and be part of an ecosystem generator of data and information. This technology has let applicability in various areas of industry, among them in medicine. Regarding to Colombia, the Internet of Things oriented to the field of health is a recently explored market, and there are few ventures around the subject, which represents an important opportunity for starting a new business in the country. Considering that there are the necessary technological and technical conditions for the development of a product based on the Internet of Things and oriented to health monitoring, was developed a feasibility study that allowed to analyze the success of the execution of the proposed project.Ítem Experimental analysis for diagnosis and fault detection in the internet of things : a home refrigerator case study(Universidad EAFIT, 2020) Zapata Ramírez, César Mauricio; Osorio Gómez, Gilberto; Mejía Gutiérrez, Gilberto; Osorio Gómez, GilbertoÍtem Industria 5.0: ¿Vuelve el hombre al centro de los procesos de producción?(Universidad EAFIT, 2019) Mantilla Avendaño, Lorena Taiz; González Pérez,María AlejandraÍtem Lenguaje de modelado de arquitectura para sistemas ciber-físicos adaptativos(Universidad EAFIT, 2020) Londoño Londoño, Luis Fernando; Mazo Peña, RaulIt is becoming increasingly common for systems to be dynamically adapted to changing contexts at run time. Such systems exhibit degrees of variability that depend on the fluctuations of the runtime in their contexts. Although dynamic variability has been addressed by long-established concepts in the field of system families, this approach is considered insufficient to meet the needs of distributed and dynamically adaptive systems such as IoT (Internet of Things)-based intelligent agriculture systems considered cyber-physical systems. These systems are required to improve the productivity and competitiveness of Colombian agricultural production. For dynamically adapted systems, approaches to support the variability of cyber-physical systems may not be just component specializations or restrictions on system variables since often the operating conditions of these systems are not predictable. In this study that seeks to establish the most appropriate techniques for managing dynamic variability in self-adapting systems, it has been necessary to address architecture modeling as a key practice in software engineering. It is considered that a modeling language that allows to represent such systems will be definitive for the production of systems with the level of quality and reliability that is required. All the results of this research are focused on enabling development companies, the tools that allow them to increase the productivity, flexibility and quality that cyber-physical systems require for agriculture. For the study it will be necessary to analyze the literature to create a language that improves the state of the art and to evaluate and perform at least one test case of a real system, this will allow to validate the proposed language. This work starts from the premise that that language should allow you to specify software, hardware, monitoring, and action components on the physical environment of each system and represent physical objects that are part of the system to be deployed. In order to test the novel nature of the proposed language, this study includes a comparison with other modeling languages proposed by the world's academic and industrial community. Finally, the study will result in a language of modeling the architecture of self-adapting systems, seen as a family or individually. The language is implemented in the VariaMos platform (http://variamos.dis.eafit.edu.co/#/) seeking to show that it can be used to represent, at the same time, reference architectures and individual system architectures, thanks to the mechanisms offered by the tool to represent and manipulate variability. The justification for the validity of the use of the proposed language is made from the presentation of a real case of a smart greenhouse. It is intended to be able to demonstrate that: (i) The modeling language has characteristics that give the possibility to represent elements such as physical and environment objects that other languages do not allow and extends the possibilities of designing cyber-physical systems (ii) The language has elements that expand the possibility of specifying in models, the components of variability that an architecture for a self-adapting cyber-physical system requires in its representation. (iii) The architecture modeling language for self-adapting cyber-physical systems while designed with IoT system design as a benchmark in a software product line domain, this language can be extended to design other cyber-physical systems.
