Implementación de un Sistema de Internet de las cosas basado en ESP32 para el monitoreo remoto de la Sala de Compresores de Artytecmo.

Abstract

This work has as context the development of a corporate internship executed in the textile cutting company ARTYTECMO. This company has a pneumatic network that is essential for its textile cutting and maintenance processes. Most of the machines use the force of compressed air to carry out their movements and maintenance technicians use it to clean the equipment. This network has shortcomings in the visualization and operation, causing frequent problems by not detecting low pressures in time, excessive humidity in the system, and restarting compressors in electrical outages. To mitigate the damage caused by the above-mentioned drawbacks, a low-cost Internet of Things system applied to the compressed air supply room is implemented to remotely monitor the most important variables. This document shows the step by step to achieve such implementation. First, the general parameters of the system are outlined, such as the architecture and components of each layer, selecting the MQTT communication protocol, the ESP32 development board, and the network connection via wifi, among others. Then the composition and distribution of the compressor room are identified, analyzing the instrumentation and designing the necessary circuits to perform the acquisition of data associated with variables such as voltage, humidity, and pressure; also, the actuators that allow remote activation of compressors and relief valves. Next, a visualization page is developed to allow the user to monitor and activate the compressor room from any device connected to the company's local network. Subsequently, the connection between the visualization application and the circuit drives and sensors through the development board is made, this step completes the implementation of the Internet of Things in the compressor room. Finally, the necessary validations are performed to verify the correct operation of the implemented system. A user guide is also created to provide guidelines for the correct use of the tool created.
