Diseño e implementación de un sistema de control de iluminación y acceso a una vivienda utilizando las herramientas básicas de la domótica.

Abstract

The current graduate research project was to design and implement a lighting control system and access to the house using basic home automation tools; it was proposed as objectives: to carry out state of art on lighting control applied in the home, to define the technical requirements necessary for the operation of the equipment. In order to achieve the objectives, as a first step, bibliographic research was carried out for learning about the different techniques and methods used in the field of home automation. From this, the decision was made to use a Siemens LOGO V8 as the main controller for the management of sensors and actuators and a Raspberry pi 4 board for the development of artificial vision algorithms. Combining these two controllers generated a higher level of safety and efficiency in each of the system operations. A sketch of the system was simulated in SolidWorks software to get a clear view of the module's end. Once the design and implementation stages were completed, the necessary tests were carried out to verify that the system works effectively in each of the functions. It is concluded that allocating the management of sensors and actuators to the LOGO controller provides greater robustness to the system because devices such as switches and luminaires work with a voltage of 110 VAC. It is essential to mention that when using a Raspberry board as a basis for the execution of artificial vision algorithms, it must be taken into account that it does not have a large data processing capacity; therefore, methods that consume few resources should be used.
