- ItemDiseño e implementación de un sistema de inyección para fertirrigación en cultivo de rosas(Universidad Técnica de Cotopaxi (UTC). Facultad de Ciencias de la Ingeniería y Aplicadas. Electromecánica, 2026-10-14) Farinango Landeta, Bryan Alexander; Freire Martínez, Luigi OrlandoThis project aimed to design and implement an automated injection system for fertigation in rose cultivation. The proposal was developed based on the characterization of the existing manual process and the identification of key variables such as pH, electrical conductivity (EC), flow rate, and pressure. A hydraulic architecture with two pumping stages was designed, integrating industrial sensors, an M5Stack Tough as the processing and supervision unit, RS485-Modbus RTU communication, and a variable frequency drive to regulate the secondary pump rated at 0,51 kW (0,7 HP) through a PI control strategy. The validation included communication, variable acquisition, pressure, flow rate, supervision interface, and controller response tests. During approximately 39 minutes of monitoring, 2,333 consecutive records were obtained with no reported communication losses. The results confirmed the functional integration of the devices, continuous acquisition of process variables, and a stable response of the control logic and the variable frequency drive. Overall, the tests validated the operation of the implemented automated system as an RS485-based monitoring, supervision, and control platform for the fertigation process, suitable for small-scale flower production units.
- ItemEvaluación experimental comparativa del desempeño energético de sistemas fotovoltaicos con configuración fija y con seguimiento solar de un eje, mediante el análisis de variables eléctricas a la entrada y salida de reguladores PWM y MPPT(Universidad Técnica de Cotopaxi (UTC). Facultad de Ciencias de la Ingeniería y Aplicadas. Electromecánica, 2026-10-14) Remache Guanoluisa, Cristian Alexis; Sangoquiza Pilatasig, Carlos Javier; Cruz Panchi, Luis RolandoThis study aimed to experimentally evaluate the energy performance of PWM and MPPT charge controllers used in an off-grid photovoltaic system. The study considered a fixed configuration and a single-axis solar tracking configuration. It used a quantitative approach and a comparative field experiment under real operating conditions. The photovoltaic system belongs to project DIRGI-CP2021-008 of Technical University of Cotopaxi. Data were collected through Modbus communication and Node-RED, and the information was processed in Microsoft Excel, electrical variables were measured at input and output of charge controllers, including voltage, current, and power transferred to the battery bank, these measurements were taken from 6:00 a.m. to 6:00 p.m. in different experimental cases. The results showed that the MPPT charge controller performed better because it operated close to the maximum power point and properly controlled battery charging stages. In contrast, the PWM charge controller depended on battery voltage and controlled the energy through pulses. It was concluded that MPPT technology makes better use of solar energy and provides more efficient energy management, especially when it is combined with single-axis solar tracking.
- ItemDiseño y construcción de una prensa hidráulica de chatarra utilizando cilindros reciclados de plataformas de carga(Universidad Técnica de Cotopaxi (UTC). Facultad de Ciencias de la Ingeniería y Aplicadas. Electromecánica, 2026-10-14) Perez Muso, Jhonathan Steveen; Prado Toctaguano, Pamela Lizbeth; Vizueta Fiallos, Gonzalo XavierThe purpose of this technological project was the design and construction of a hydraulic scrap metal press using recycled cylinders from loading platforms. The machine is intended for the compaction and bending of metal waste generated by mechanical and industrial activities. For the development of the project, a field methodology based on the direct observation of the activities currently carried out at Megacons Company was applied, which made it possible to identify the technical needs required by the company, including scrap metal compaction, axle bending, and other similar activities, thus contributing to establishing the necessary elements for the design and construction of the machine. Based on the information collected through the company’s owner and workers, the structural, mechanical, and hydraulic characteristics necessary for the construction of the press were determined. Likewise, the reuse of cylinders from loading platforms was considered, which were in suitable condition, allowing the integration of the other structural components necessary to generate the required compressive force to reduce the volume of metal waste, facilitating its transportation and handling. In this way, the project constitutes an innovative and functional technological alternative that contributes to scrap metal management and the development of work activities that do not put workers’ health at risk.
- ItemDiseño construcción de una máquina para corte y recolección de su producto del coco de agua(Universidad Técnica de Cotopaxi (UTC). Facultad de Ciencias de la Ingeniería y Aplicadas. Electromecánica, 2026-10-14) Quinatoa Taco, Luis Alcides; Gallardo Molina, Cristian FabianThis research project addresses the design and construction of a machine for cutting open and collecting coconut water, with the aim of optimizing the beverage extraction process, reducing operating times, and mitigating the ergonomic risks associated with manual processing. The methodology applied was based on the Waterfall model, structured sequentially into five phases: analysis, design, implementation, testing, and adjustments. During the analysis phase, the physical and geometric properties of the coconuts were characterized, determining a required cutting force of 1,500 N. In the design stage, a connecting rod-rocker arm mechanism was dimensioned and powered by a 2 HP (1.26 kW) electric motor, using A36 steel for the support structure and AISI 304 stainless steel for the surfaces in contact with the food product, thereby ensuring food safety. Functional tests conducted on 50 samples validated the system’s kinematic stability, confirming clean cuts, efficient power consumption, and effective liquid collection. Finally, the economic evaluation demonstrated the prototype’s financial viability, concluding that automating this process significantly increases productivity and safety in the agro-industrial sector.
- ItemAnálisis de fallas en el banco de corrección de factor de potencia en la planta de pintura en la empresa Ciauto Cia Ltda(Universidad Técnica de Cotopaxi (UTC). Facultad de Ciencias de la Ingeniería y Aplicadas. Electromecánica, 2026-10-14) Telenchana Quilligana, Glenda Margoth; Toapanta Andrango, Stalin Israel; Freire Martínez, Luigi OrlandoThis research analyzed the failures affecting the operation of the power factor correction bank in the paint plant of CIAUTO LTD. The study was conducted using a quantitative approach, including a technical inspection of the bank, verification of the measurement system, and analysis of the electrical parameters obtained during a measurement campaign with the Fluke 435-II power quality analyzer. The diagnosis determined a nominal installed capacity of 105 kVAr, compared to a recorded capacity of 99.4 kVAr. In addition, inadequate connections in the current transformers were identified, associated with differences between the readings of the DUCATI DUCA-LCD96 panel analyzer and the Fluke 435-II. The electrical analysis showed that the power factor varied according to load conditions, reaching values between 0.97 and 0.98 during production and an average of 0.79 under low demand. Based on these results, it was proposed to restructure the bank to a nominal capacity of 130 kVAr, distributed in six steps of 5, 10, 25, 25, 40, and 25 kVAr. For the low-demand condition, a compensation requirement of 4.89 kVAr was determined, and a 5 kVAr capacitor was selected. Simulation in DIgSILENT PowerFactory allowed evaluation of this step, resulting in an increase in the power factor from 0.73 to 0.98 for the analyzed condition. The proposal incorporates backup steps and reuses existing components, improving the adaptation of the bank to the identified operating conditions.
