Implementación de un módulo automático para replicar el ensayo de Herschel para el laboratorio de diagnóstico técnico y eficiencia energética de la Facultad de Mecánica

Abstract

The objective of this degree work was to implement an automatic module to replicate the Herschel test for the Laboratory of Technical Diagnosis and Energy Efficiency of Mechanics. It is proposed as an opportunity to improve the learning of the students of the faculty. It was sought to solve the problem of earth rotation relative to the sun, through a prototype which covers all the needs of the test, automating the processes and the temperature census, also allowing the taking and data collection from a faster and more efficient way. A design was made in a 3D modeling software, obtaining the model for its construction, which allowed selecting the most optimal components. At the same time the electronic control circuit was designed using Arduino and an app in inventor that allows to obtain a graph of the real-time temperature measured by the PTC sensors. Subsequently, the data collection and the statistical analysis of the data obtained were carried out, using the T-student model for a normal distribution or Wilcoxon to a non-normal distribution. Finally, the laboratory guide for the Herschel test, the operation manual and the maintenance manual for the module were developed. It is concluded that the constructed module allows to measure and visualize in a precise and simple way the spectra of color temperatures, by means of a prism and using technology, it has been verified that obtaining these results is practically instantaneous. It is recommended to carry out the test on sunny days to obtain more accurate results, the season of the year must also be considered to avoid decalibrate the module.
