Implementación de dos sistemas de control de temperatura mediante la acción de control ON/OFF para el Laboratorio de Tecnología Industrial de la ESFOT : Desarrollo del algoritmo de control, HMI y registro de datos.

Abstract

This project presents the development of an algorithm for the control, monitoring, and supervision of temperature and data logging, both locally and remotely, for two didactic modules. For local control, an Arduino will be used and programmed in a low-level language. For remote control, a PLC (Programmable Logic Controller) will be used, and its respective HMI (Human-Machine Interface) will be developed. The modules must constantly measure temperature data and allow the input of the reference (set point). To carry out the logging, a microcontroller (Arduino) will be used to visualize the data and generate tables in Excel. The didactic modules will help strengthen knowledge related to sensor conditioning, temperature control, and data logging. This project is organized into seven chapters, which are described below: The first chapter explains the introduction of the project, in which the component is described, the general and specific objectives are outlined, the scope is defined, and a brief explanation of the theoretical fundamentals necessary for the project is provided. The second chapter explains the procedure followed to carry out the project. A code is developed for the ON/OFF temperature control both locally and remotely, taking into account the use of an Arduino, PLC, and HMI. Finally, the data logging through Excel is elaborated. The third chapter presents the results obtained from the development of the code for the Arduino, the control algorithm for the PLC and HMI, and the data logging of the module, as well as the user and maintenance manuals necessary for its correct use and operation. The fourth and fifth chapters contain the conclusions and recommendations obtained from the project. Finally, the sixth and seventh chapters include the bibliographic references and annexes of the document.
