    Lubricación automática para una escalera eléctrica con monitoreo de cadena
    (Universidad de Cuenca, 2025-03-13) Avila Castro, Cristian Andres; Abril Rivera, Raúl Alfredo
    The automatic lubrication system designed for this work represents a key need for escalator maintenance companies. Currently, lubricating the chains and checking their tension presents several difficulties, which generates a waste of time and materials, in addition to representing a high risk for the collaborators who perform these tasks. For the development of the chain lubrication and monitoring system, an analysis was carried out based on the author's experience as a maintenance technician, in which the high risk associated with these tasks was identified, as well as the waste of materials and the lack of effective lubrication. Subsequently, the system structure was designed, defining the elements to be used and the corresponding programming. The design is based on the experience with escalators, with the objective of automating processes that, in certain models, are still carried out manually. Therefore, alternative solutions are proposed that best suit the maintenance needs. As a result, a lubrication control system is developed, defining the controller element and its components. Finally, the system is evaluated by means of a scale model, which allows to analyze the operation of both the ladder and the lubrication system, in order to optimize it is performance through simulation.

    Rehabilitación de módulos del sistema CIM del laboratorio de máquinas y potencia de Ingeniería Eléctrica de la Universidad de Cuenca
    (Universidad de Cuenca, 2025-03-08) Tinizhañay Beltrán, Freddy Alejandro; Romero Quezada, Erick Alejandro; Mejía Lojano, Juan Sebastián; Abril Rivera, Raúl Alfredo
    The rehabilitation of the modules of the CIM (Computer Integrated Manufacturing) system of the machinery and power laboratory of Electrical Engineering at the University of Cuenca is presented as a fundamental project to improve the academic and practical training of students. This work seeks to update and optimize the existing modules, incorporating modern technologies that facilitate more effective learning and aligned with the demands of today's labor market. The main objective of this rehabilitation is to achieve functionality and efficiency of the CIM system, allowing students to acquire competencies in the integration of industrial processes, automatic control and resource management. The methodology includes a thorough diagnosis of the current state of the modules, followed by the implementation of technical and technological improvements. Tools such as simulators and specialized software will be used to allow a better understanding of industrial processes. Among the specific activities to be carried out are the technical evaluation, which consists of the analysis of the current state of the modules, identifying failures and areas for improvement, and the technological upgrade, which involves the integration of new components and software that meet the current needs of the industrial sector.

    Simulación de un sistema para ascensor controlado por PLC
    (Universidad de Cuenca. UCUENCA-TEC, 2025-10-31) Cornejo Domínguez, William Geovanny; Pintado Nivicela, Ismael Sebastián; Abril Rivera, Raúl Alfredo
    The purpose of this project is to build automated elevator control for a model where a Programmable Logic Controller is in charge of the system. We want this system to explain the advantages of automation in elevator systems and provide hands-on learning methods to grasp the fundamentals of industrial control. Automatic elevator systems need to function properly in cities and commercial spaces. PLCs function as energetic control elements that process data efficiently to connect devices and produce safe results. The integration of a PLC in the model offers an experience that being close to the actual ones allows to evaluate the possible improvements in the service. It can also act as a medium between education and the workplace to prepare students for future jobs in automation and control. It is based on its educational advantages, the promotion of technical thinking throughout the development of the practical activity and the skills of the participants in the context of the work process. Also, the emulation of systems and the issue of safety are complementary energetic aspects that add value in education and training in the field. The elevator model is initialized with a PLC in charge of controlling the actions around the cabin such as going up, going down, stopping at the required floors and reacting to user responses. These are position sensors which inform the PLC of the exact location of the elevator.
