Implementación de un sistema automático para controlar la iluminación y proyección, aplicable a entornos academicos de la Escuela de Ingeniería Industrial (Caso Salón Rosado).

Abstract

The objective of the present titration work is to implement an automatic system to control lighting and projection, applicable to academic environments of the industrial engineering school in the pink room. To fulfill this objective, the following methodology is applied. First, it is designed the system that is responsible for providing adequate lighting in the pink room based on the maximum and minimum levels defined by the "European Standardization Commission of the UNE 12462-1 standard." Second, the necessary luminaires are calculated applying the method of lumens using as main tools: DIALux software and analytical procedure. After this, curtains, sensors and the controllable logic programmer (PLC) are selected, taking into account the tables of weightings provided in the aforementioned regulations. Once the selection has been made, the construction of the automatic system and the programming in the arduino continue, to finely perform performance tests considering the different conditions of use of the pink room. To analyze the results, an evaluation is made with respect to to the determination of the level of illumination (in the morning, afternoon and evening) by means of the Official Mexican Standard NOM-025-stps-2008; and the energy consumption that the pink room generates before and after the implementation of the automatic system. In addition to them, the costs represented by said implementation are calculated. In conclusion at the end of this work, the degree of brightness of the room is obtained as a result. average of 500 lux, for which only 12 lamps are needed. In addition, the energy consumption is reduced by 50%, which generates lower costs. It is recommended to periodically review the regulations of the sensors to avoid malfunctions, also suggest the implementation of automatic lighting systems in other academic environments.
