Desarrollo de un sistema para controlar el préstamo de los equipos de laboratorio de telecomunicaciones de la Universitaria Agustiniana
Ruiz-Castelblanco, Christopher Steevens; Valencia-Plata, Guillermo Fernando
This document consists of a degree option project which seeks to automate equipment control and loan processes in the Telecommunications laboratories of the Uniagustiniana University where its problems are based mainly on the fact that it is difficult to develop work or practices in which the use of any equipment that the university has, not knowing whether or not they are available or how much time is available to use these equipment, since more students or even teachers may need them. Qualitative tools were used, obtaining information from various sources by conducting observation surveys and analyzing the responses obtained by each of the interviewees, carrying out the analysis of this, what is sought is to provide a solution through an information system that allows the personnel in charge to carry out a control of each of the equipment where you can see information about the equipment, the loans made, and the users to whom the loan is made, favoring students and the personnel in charge of making the loan of laboratory equipment, also generating an ecological impact by not having to use sheets of paper to fill out the loan form.
Diseño de un curso para apropiar conceptos básicos de telecomunicaciones, integrando herramientas tecnológicas en la educación apoyada por la virtualidad
Villarreal-López, Martha Isabel; Valencia-Plata, Guillermo Fernando; Arias Arias, Nubia Constanza
The present article is the result of a research carried out in the framework of the specialization in pedagogy of the Augustinian University, to help solve the problem of desertion that has been evidenced in the Telecommunications Engineering program, due to the difficulty in learning basic concepts of communication systems. The research is qualitative and was carried out with a social critical approach, using an ethnographic method to characterize the student population through the implementation of two surveys. To help solve this problem, the design of a course was proposed by being sensitive to the students' perceptions and their learning styles, without ignoring the stages of their cognitive processes. Through these perceptions and learning styles, the topics to be covered in the course and the technological tools on which it will be based were selected
Diseño de un sistema para visualizar y generar alertas de temperatura y humedad en los vehículos termoquin con información en tiempo real.
Arias-Sanchez, Brandon Steban; Valencia-Plata, Guillermo Fernando
The project was carried out with the idea of investigating and mitigating the losses of food that occurs in thermoquin vehicles due to failures in their cooling systems, which is a critical issue for food companies that must transport from one side to another said loads, whether by vehicles with an age or these vehicles with maintenance failures, there is no truthful information for the driver when anomalous events are happening in the vehicle's refrigerant refrigerator. In this project, a system is developed through which it is desired to monitor and visualize the temperature and relative humidity of the environment in the refrigerant refrigerators of Termoquin vehicles, through an IoT network in which through a web platform we can visualize the data collected on these variables, this in order to generate a parameterization of variables and generation of alerts to the people in charge of the vehicles. Bearing in mind the technological advances that have been observed in our time, it is possible to implement electronic devices such as the Arduino sensor and the GPRS module to take the variables and parameterize the alerts through the Ubidots web platform.
Sistema de irradiación y monitoreo de ondas no ionizantes en la banda de 3.5 GHz sobre un cultivo típico de los ecosistemas colombianos
Moreno-Cardenas, Ivonne Soraya; Tique-Perez, Marisol; Valencia-Plata, Guillermo Fernando
This work aims to publicize the relevance that 5G technology is taking worldwide, additionally with the implementation of a non-ionizing wave radiation system using software such as GNU Radio Companion to perform all equipment programming and testing to reach the required frequency, which in this case is 3.5 GHz. In order to carry out this process, research was carried out on the equipment that the Universidad Agustiniana has, as well as the investigation of each of the antennas to carry out the transmission and reception of the signal. In addition, the data obtained from the system is captured by means of a database connection which was made in the generated code of the GNU Radio Companion software of the signal reception program, in the programming language Python, whose information was stored on a server and a mobile application was generated to make possible the visualization of the data in designing in Ionic.com this process encompasses all the system development proposed in the objectives.
Sistema para irradiar cultivos con ondas de las tecnologías LoRa y wifi, que también permita su monitoreo en tiempo real
Aguirre-Marroquin, Johan David; Medina-Sandoval, Nikol Sharith; Valencia-Plata, Guillermo Fernando
This paper presents the process carried out to characterize a system that allows crop irradiation using LoRa and wifi technologies, while allowing realtime monitoring of several variables. The irradiation subsystem was developed through the use of different modules capable of emitting electromagnetic waves in the required spectrum ranges, specifically 433 MHz and 2.4 GHz, thus providing detailed information on how the packages are formed and how wireless transmission is performed in each of the technologies. On the other hand, the monitoring subsystem was based on the use of sensors and microcontrollers that allow obtaining the necessary variables within the crop. To carry out the assembly and design of both subsystems, several scientific research methods were used, which allowed obtaining accurate information to support and develop each part of the project. At the end of the development of the system, fulfilling all the established objectives, the process of physical assembly of the irradiation subsystem is shown in detail, as well as the design of the data acquisition subsystem. In addition, use was made of various cloud platforms for monitoring and storage of the variables studied. Likewise, the communication protocols used for the transmission of information between the devices and the platforms were studied in depth. Finally, we describe how the system and platforms were implemented, detailing how alerts are generated according to the expectations and environmental restrictions of the crops.
