Abstract
[Resumen]: La Universidad de A Coruña ha desarrollado el proyecto Campus SUDS (EQC2019-006507-P), financiado por el Plan estatal I+D+i 2017-2020, con instalaciones SUDS en los campus de Elviña y Zapateira. Como parte de este proyecto, se ha creado una instalación situada junto al pabellón de estudiantes de Elviña, destinada al análisis de aguas residuales que llegan al río de Elviña. El sistema bombea las aguas residuales a un tanque y posteriormente a un canal equipado con sensores que miden parámetros de calidad del agua como pH, turbidez, redox, temperatura, así como el nivel, el caudal y la velocidad. Los datos son enviados y se almacenanados en el servidor del proyecto. El sistema requiere limpiezas periódicas debido a la suciedad de las aguas residuales; para ello, se dispone de un PLC que permite, mediante relés, controlar la bomba y las válvulas para realizar el proceso de limpieza de forma automática. Además, el PLC envía los datos del caudal, la velocidad y el nivel de agua del río y el estado del proceso de limpieza, mediante el protocolo MQTT, al servidor donde se almacenan en una base de datos. El objetivo de este proyecto es desarrollar una aplicación web segura que permita la visualización en tiempo real e histórica de los datos recogidos por la instalación, la supervisión del estado del proceso de limpieza y el control manual de los elementos del sistema (bombas y válvulas), optimizando así la gestión, monitorización y operatividad de la instalación SUDS. Para dicho desarrollo se han usado tecnologías de desarrollo ampliamente usadas y el proyecto se ha gestionado mediante la metodología ágil Scrum.
[Abstract]: The University of A Coruña has developed the Campus SUDS project (EQC2019-006507-P), funded by the Spanish National R+D+I Plan 2017-2020, with SUDS installations on the Elviña and Zapateira campuses. As part of this project, a facility has been created next to the student pavilion in Elviña, intended for the analysis of wastewater flowing into the Elviña river. The system pumps the wastewater into a tank and subsequently into a channel equipped with sensors that measure water quality parameters such as pH, turbidity, redox, temperature, as well as level, flow rate, and velocity. The data are sent and stored on the project server. The system requires periodic cleaning due to the dirtiness of the wastewater; for this purpose, a PLC is used to control the pump and the valves via relays in order to carry out the cleaning process automatically. In addition, the PLC sends the data on flow rate, velocity, and water level of the river, as well as the cleaning process status, via the MQTT protocol, to the server where they are stored in a database. The objective of this project is to develop a secure web application that enables real-time and historical visualization of the data collected by the installation, supervision of the cleaning process status, and manual control of the system elements (pumps and valves), thus optimizing the management, monitoring, and operability of the SUDS installation. Widely used development technologies have been employed for this purpose, and the project has been managed using the agile Scrum methodology.
