Módulos de hardware para aplicação em arquiteturas descentralizadas de automação residencial

Abstract

This work aims to develop modules for home automation using FPGA as a controller device to demonstrate its use in applications in which usually other types of controllers are used. The project is based on a decentralized architecture, using two controllers and two plants. A hardware for each FPGA was developed and also a test apparatus, representing a house with sensors and actuators. For the interconnections between the parts, two interface boards were also manufactured, which make the connections between the model and the FPGAs, besides the implementation of a network protocol (using Ethernet and TCP/IP) for future application in the interconnection of the two control centers. Also, as a human-machine interface, a software (containing a graphical user interface) was developed for Linux, furthermore the assembly of a circuit with buttons working in parallel to the interface. The system proved to be efficient, representing how would be the operation of this same project installed in a real residence. Furthermore, it has been deduced that FPGAs can be used as controllers for more complex systems than a house with a few elements.
