    The objective of this research work is to design an intelligent control system for a hydroponic greenhouse NFT (Nutrient Film Techiquel) that is focused on the cultivation of curly lettuce (sativa var. Crispa). The system was developed to implement the use of technologies for the agricultural sector, speed up harvest time, using a small physical space to cultivate on a large scale, ensuring the quality and sanitation of the products, highly recommended for human consumption. As for the electronic part, it is composed of a controller board with a CortexM3 ARM microcontroller, it has standard WiFi connectivity for monitoring variables, connectivity with an IoT platform and an application developed for Android Os, as well as local visualization with an HMI touch screen. Sensors pH, electrical conductivity, temperature, humidity, light intensity, and level are those that collect the data for the monitoring and automation of nutritional solutions with PID control, onoff control for ventilation, tank filling and system start-up led light. LED light covers the red and blue colors of 450-680 nm wavelength of the electromagnetic spectrum, the importance of lighting helps increase biomass through the absorption of light in the photosynthesis process increasing the time of daylight DLI. Due to the results, the system developed for hydroponic cultivation helps with the saving of economic, human and water resources. There fore, it is profitable and can bring great benefits to farmers, the ecosystem, and consumers.

    Mejoramiento del sistema de control y monitorización para el sistema de agua de enfriamiento NSAE de la Central Hidroeléctrica San Francisco
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2021-08) Villalva Freire, José Alberto; Salazar Logroño, Franklin Wilfrido
    In this project, the improvement of the New Cooling Water System (NSAE) is carried out, a subsystem that is a fundamental part of the electric power generation process produced by the San Francisco Hydroelectric Plant, and whose function is to maintain normal temperatures. Generation Units of the Power Plant through the storage and distribution of cooling water, with the use of pumps that lead this liquid through pipes connected to the cooling systems of the generators. The system that was installed in 2012 did not provide a local monitoring interface for the process variables, which is why it was necessary to install an HMI screen on the system control panel, thus increasing its reliability, allowing visualization complete process through monitoring the status of the elements that make up the system: pumps, storage tank levels, central air extractor, flow valves, pressure switches, temperature, flow, voltage measurements, single-line diagram of the system, three-wire diagram of frequency inverters, history of events, status of all PLC variables, status graphics of analog variables. With this improvement, it is now possible to contrast the status of the system between the new interface, the SCADA and the on-site reading of the equipment and instruments that comprise it. In addition, the design of a Modbus network is carried out that allows the acquisition of parameters of the frequency inverters from the new interface, including a new temperature sensor for the Pumping Tank. The methodology used is theoretical-practical, since the interface and network designs are oriented to the requirements of the Central, providing them with an informative, intuitive and accessible interface, thus improving the human-machine interaction between the operators and the system. through the use of industrial communication networks.

    Sistema de monitoreo y automatización para cisternas en el proceso de anodizado en la Corporación Ecuatoriana de Aluminio S.A.
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2021-06) Quintana Tenorio, Galo Fabián; Ayala Baño, Paulina Elizabeth
    The research work presents the design of a monitoring and automation system for tanks in the anodizing process in the Ecuadorian Aluminum Corporation S.A. The company currently lacks a monitoring and control system for tanks, due to this there are economic losses, environmental and human effects due to a constant overflow. For these reasons, the present project aims to design a system that allows monitoring and controlling the level of the liquids they contain. It was decided to monitor the level of the tanks, by means of sensors that emit the signal to the controller, which processes said signals and, through the Ethernet / IP communication protocol, shows them in an HMI interface, this is used for real-time monitoring of the variables, equipment status information, pump ignition control, solenoid valves and level versus time graphs, also beacons are used that help the operator to visually know the current capacity of the tanks. The programming of the programmable logic controller was carried out in Ladder language using the RsLogix 5000 software and with the DopSoft Software the graphical interfaces of each tank were designed. For the validation of the control system, several functional tests were carried out, resulting in the total elimination of tank overflows, establishing a continuous production of the profiles and at the same time remote monitoring of all the process variables from any point of the plant.

    Sistema electrónico para el monitoreo del almacenamiento de diesel del Hospital General Ambato
    (2018) Analuisa Criollo, Oscar Iván; Brito Moncayo, Geovanni Danilo
    En la presente investigación se desarrolló un sistema encaminado a mejorar el monitoreo del nivel de diesel en el Hospital General Ambato. El diseño y funcionamiento del sistema ofrece un monitoreo en tiempo real y cuenta con alertas a un dispositivo móvil cuando algún tanque se encuentre en un nivel medio o bajo. De esta manera mantener un nivel apropiado en cada uno de los tanques de almacenamiento, ya que por ningún motivo estos pueden quedar vacíos porque podrían inhabilitar diferentes áreas del hospital. La metodología del diseño está basado en el monitoreo local a través de una pantalla HMI y remotamente por medio de la plataforma en la nube. Las alertas de escasez de diesel se visualizan por medio de luces indicadoras, sonoras y de forma remota con notificaciones a una aplicación desarrollada en Android Studio. El sistema de monitoreo está diseñado para aplicarlo a los cuatro tanques que conforma el almacenamiento total de diesel y el prototipo está instalado en un tanque, el cual alimenta al generador eléctrico.

    Sistema de control y monitoreo para bombas de drenaje y vaciado de la Central Hidroeléctrica San Francisco
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera Ingeniería en Electrónica y Comunicaciones, 2017-06) García Bermeo, William José; Manzano Villafuerte, Víctor Santiago
    En el presente proyecto, se implementa un HMI para el control y monitoreo de un subsistema de la Central Hidroeléctrica San Francisco, denominado de vaciado y drenaje. Este subsistema, es controlado por 4 motobombas que tienen por objetivo la extracción de agua proveniente de infiltraciones (casa de máquinas, edificio de control, área de montaje y túnel de acceso principal) contenida en un pozo llamado de drenaje La interfaz permite monitorizar: el nivel de agua en el tanque de drenaje, información detallada de las bombas y sus variadores de frecuencia, conexiones de fuerza (diagramas trifilares), gráfica del nivel del tanque versus tiempo y un historial de eventos. En cuanto al control, puede comandar señales para que las bombas operen de forma remota automática o local con accionamiento manual. La metodología utilizada es de campo, debido a que el diseño está orientado a los requerimientos de la Central Hidroeléctrica San Francisco, proveyendo un alto grado de disponibilidad del sistema de drenaje y vaciado con una interfaz informativa, accesible e intuitiva. ABSTRACT In the present project, an HMI is implemented for the control and monitoring of a subsystem of the San Francisco Hydroelectric Power Plant, known as “for emptying and drainage”. This subsystem is controlled by 4 motor pumps that aim to extract water from infiltrations (engine room, control building, assembly area and main access tunnel) contained in a well called “of drainage”. The interface allows monitoring: the level of water in the drainage tank, detailed information on the pumps and their frequency converters, power connections (three-wire diagrams), tank level graph versus time and a history of events. As for the control, it can command signals for the pumps to operate remotely automatically or locally with manual operation. This project uses field methodology, because the design is oriented to the requirements of the San Francisco Hydroelectric Power Station, providing a high degree of availability of the emptying and drainage system with an informative, accessible and intuitive interface.
