Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2023-03) Pérez Reyes, Freddy Josué; Sánchez Zumba, Andrea PatriciaThe continuous progress of technology and the application of the Internet of Things (IoT) in the agricultural sector has allowed an advance in the systems that favor the development of crops. This project develops a control and monitoring system for the cultivation of vegetables under greenhouse in the Huachi Grande parish of Ambato. The objective is to provide the grower with an autonomous system capable of making intelligent decisions without the need for constant supervision by a person. The system allows monitoring and control of temperature and humidity, as well as pH levels and the amount of radiation that the plants receive during the day, and also has an artificial lighting system. The purpose of this research work is to provide a favorable environment for cultivation inside a greenhouse, for this we work with temperature and humidity sensors, soil moisture sensors, pH sensor and solar radiation sensor. In order to control the temperature inside the greenhouse, two fans and an automatic curtain closing and opening system by means of a low-speed electric motor are used, as well as soil humidity control, which is carried out by means of drip irrigation. On the other hand, for pH monitoring, a sensor is used for the water that enters the crop through the irrigation hoses. Finally, a solar radiation sensor is used to monitor the amount of radiation received by the plants, in order to activate artificial lighting, if necessary, with the objective of increasing the period of time during which the plant performs photosynthesis. The technology used is based on LoRaWAN and the MQTT protocol. The system has two Lora nodes and a gateway to communicate with the server and connect the system to the Internet. To control the system, an HMI based on Node-RED is used, which allows constant real-time monitoring, automatic or manual control of the system and visualization of daily statistics. In addition, the system has a control and monitoring through the Telegram application, through which the producer receives alert notifications and can control the system manually.Item Sistema de monitoreo de variables de macro medición para la gestión del recurso hídrico y el control de calidad de la EP-EMASA-PM,(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2022-09) Cacuango Labre, Richard Stalyn; Sánchez Zumba, Andrea PatriciaThe research project aims to provide a system that facilitates the monitoring of macro measurement variables, for the management of water resources and water quality control automatically, allowing the results to be Viewed through web and mobile devices. Taking as reference the levels of turbidity, pH, chlorine and temperature, as the main variables in the control of water quality, while the acquisition of the level of flow and consumption are used for the management of water resources. Once these values are acquired, they are compared with the INEN 1108: 2014 standard at the national level and with the water quality guide provided by the WHO at the international level. The acquisition of the sampling data in the five drinking water container tanks is carried out twice a day, during the work day of the personnel in charge of the Public Company of Drinking Water, Sewage and Sanitation of the Pedro canton Moncayo, allowing rapid action to be taken when control of any variable that presents levels that are inadequate for human consumption is required. The monitoring system is developed around the Heltec wireless stick lite Microcontroller with free software, which allows lowering the manufacturing costs of the system. This microcontroller is responsible for receiving the variables obtained by the sensors, in order to send the information through a Gateway to the The things stack Enterprise server, using the LORA network. The information is later sent to the Node Red server where the information is managed to finally be stored in the MySQL database. This server also allows the display of information, through a dashboard, located on the localhost of the server. To provide greater access security, the record of the personnel in charge of monitoring is previously generated, based on an email and a password, which are stored in the MySQL database. To verify its functionality, tests are carried out over a period of one month with continuous data collection every 30 min, in addition to providing greater reliability, in case of power failures, an energy backup built on the basis of solar panels is incorporated, allowing store energy in Li ion batteries which allow the autonomous operation of the system in a period of 24 hours.Item Centro de mando y control portátil para aviones tácticos UAVS colibrí para el centro de investigación y desarrollo de la FAE(Universidad Técnica de Ambato.

Julio EnriqueThe research work consists of the implementation of a portable command and control center to improve the visualization of information on the ground and to increase the coverage for the transreception of data and video, thus ensuring the survival of the aircraft during the flight missions of a UAV of the CIDFAE. To do so, we started with an analysis of the current control and monitoring conditions of the center's aircraft in flight operations, in order to determine the shortcomings and requirements to improve the aforementioned operations.This allowed sizing the components necessary for the command and control center to function properly, for which selection characteristics were established, such as cost, dimensions, technical specifications, taking into account the structure of the command and control center. After acquiring the equipment, the design of the portable command and control center, both exterior and interior, was made, the printing and laser cutting of the same in a suitable material and proceeded to install each of the components inside the center, then the necessary connections were made and configured by means of aeronautical software to verify its operation. Finally, a set of tests were carried out inside the base of the Research Center to evaluate the operation of the command and control center and the efficient visualization of the video and all the flight variables during its operation. All this procedure resulted in obtaining a portable command and control center that is serving as support in the military missions of control and monitoringprovided by the CIDFAE in different parts of the country.Item Sistema electrónico de monitoreo y alerta para la conservación de muestras de laboratorio y cultivos de bacterias en el laboratorio clínico Muñoz de la ciudad de Guaranda.(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2022-03) Del Salto Paredes, Anthony Danilo; Brito Moncayo, Geovanni DaniloThe present project describes the development and implementation of an electronic monitoring and alert system for the conservation of laboratory samples and bacterial cultures in the Muñoz Clinical Laboratory, located on Convención de 1884 and Selva Alegre street in the city of Guaranda , province of Bolívar, based on the main threats to which laboratory samples are exposed due to their temperature stability, as well as the importance of maintaining an optimal environment for the monitored growth of bacteria, fundamental tests for the determination of infections caused by pathogenic microorganisms, where an appropriate treatment is subsequently carried out by the responsible doctor. For the development of this proposal, end nodes made up of sensors and wireless transmitters were used, which send the data of the variables of interest such as temperature and presence of gas to a main server through the MQTT protocol, where, through the broker, these data are displayed in a easy-to-use web interface for laboratory staff, constantly monitoring the refrigerators in the equipment and bacteriology area, in addition to the culture oven where the "seeded" samples are placed, for their respective analysis and performance of antibiogram. Additionally, a constant observation was maintained on the presence of gas in the bacteriology area due to the continuous use of Bunsen burners, which work on the basis of liquefied petroleum gas (LPG), which are used for the sterilization of handles and other materials used for the “seeding/culture” of bacteria. The entire system has alarms in the respective areas, also an alert via messaging through the Telegram platform, allowing constant monitoring by health professionals in the clinical laboratory. This system provides the Muñoz Clinical Laboratory with a low-cost way to reduce the risk of damage in samples and/or reagents used in the equipment, due to their fragility and considering the stability of the samples according to the laboratory examination needed to perform; in addition to this, trying to ensure an optimal environment for the growth of bacteria, by monitoring the culture oven, the temperature can be manually corrected and, in this way, increase the life time of the bacteria (in case of presence), for its proper growth and relate it directly to a good diagnostic by the laboratory.Item Sistema electrónico de monitoreo y alerta en los tanques de almacenamiento de líquidos tensoactivos catiónicos en la planta Indiquimica S.A.(Universidad Técnica de Ambato.

Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2021-08) Llundo Eugenio, Edisson Patricio; Pérez Ruiz, Diego Israel; Ayala Baño, Elizabeth PaulinaThis research project has been carried out in order to respond to the need of the CIDFAE to efficiently monitor the borders of Ecuador, due to the lack of advanced equipment such as thermal cameras installed in unmanned aerial vehicles (UAV), which monitor and control criminal acts such as smuggling that occur 24 hours a day and that at night it is more difficult to use tools such as cameras to capture images. That is why a video surveillance system is applied which consists of the use of a fixed wing UAV's (unmanned aerial vehicle) in which a thermal camera is installed to obtain images that are captured by the heat emitted by the body. The prototype gives us the possibility of transmitting data at 5 km, giving the facility to install a repeater in the event that transmission requires a greater range. In the development of the system that is applied in the project, calculations have been made for the selection of equipment for the correct operation of the air unit, which are motors, servomotors and thermal camera, subsequently, the acquisition of said equipment has been made to finally adapt them and configure them to the UAV. Finally, the data transmission and reception equipment has been programmed and configured for correct operation. The final result of the project was determined that the VDC7 system has been used for the transmission of data and video from a UAV to the control center, this system has been optimal because if it is required to extend the transmission distance, it can be used as repeaters .Item Analizador de calidad de energía eléctrica con supervisión en tiempo real(Universidad Técnica de Ambato.
