Abstract(s)
A domótica é o termo usado para referir à automatização de um edifício. Um sistema deste tipo pode controlar iluminação, climatização, sistemas de segurança, entre outros. A domótica tem como objetivo aumentar o conforto e segurança, assim como, melhorar a eficiência energética das casas. Na área da domótica existe uma vasta gama de tecnologias disponíveis, contudo, o Z-Wave destaca-se graças ao seu desempenho e `a interoperabilidade entre produtos de diferentes fabricantes. Este, é um protocolo de comunicação por radiofrequência dedicado á transmissão de mensagens de controlo. Dada a cada vez maior, relevância do protocolo Z-Wave na domótica, este projeto foi realizado com o intuito de estudar este protocolo, perceber as suas capacidades e o quão acessível, em termos de disponibilidade e custos, é desenvolver sistemas com este protocolo. O projeto realizado consiste no desenvolvimento de um controlador de domótica Z-Wave que, para além de conseguir atuar, configurar e recolher informações de dispositivos que usem este protocolo, incorpore sensores de forma a medir determinadas grandezas e que seja capaz de controlar estas grandezas atuando dispositivos Z-Wave. O sistema desenvolvido tem como elemento central uma placa de desenvolvimento, que será responsável por gerir a rede Z-Wave, obter e efetuar o controlo PI das grandezas medidas pelos sensores e onde irá estar alojada uma página web que servirá de interface gráfica. A placa de desenvolvimento será acoplada uma antena Z-Wave que adicionará ao sistema a capacidade de comunicar através deste protocolo. Para validar o correto funcionamento do sistema foi utilizado um analisador de rede Z-Wave, que permite visualizar as mensagens transmitidas na rede com a qual este está emparelhado. Com este, foi possível observar as mensagens enviadas pela rede aquando da atuação de um dado dispositivo através da interface gráfica, assim como, os reports enviados pelos dispositivos Z-Wave para o controlador. Para além disso, foram realizadas várias experiencias para validar os controladores PI implementados. Estas, consistiram na variação dos ganhos proporcionais e integrais, de forma a ver a influência de cada um deles e comparando com o que seria de esperar teoricamente.
Home automation is a term used to refer to the automatization of a building. A system of this kind can control lightning, temperature, security systems, among others. Home automation has the objective of increasing comfort and security, as well as, improve home’s energy efficiency. In the home automation field there’s a vast range of technologies available, however, Z-Wave stands out thanks to its performance and interoperability between products of different manufacturers. ZWave is a communication protocol, that uses radiofrequency, dedicated to the transmission of control messages. Given the growing relevance of the Z-Wave protocol in home automation, this project was done with the intention of studying this protocol and understand its capabilities and how accessible, in terms of availability and costs, it is to develop systems with this protocol. This project consists in the development of a home automation Z-Wave controller that, besides being able to actuate, configure, and get informations about devices that use this protocol, it incorporates sensors to measure given physical quantities and that is able to control these, actuating Z-Wave devices. The system developed has as central element a development board, that will be responsible for managing the Z-Wave network, get and do the PI control of physical quantities measured by the sensors and where it will be hosted a webpage that will work as graphical interface. To the development board it will be connected a Z-Wave antenna that will add to the system the ability to communicate through this protocol. To validate the system, it was used a Z-Wave network analyser, that allows to see the messages in the network with which the analyser is paired. With this, it was possible to see the messages sent through the network when a given device is actuated through the webpage, as well as, the reports sent by the Z-Wave devices to the controller. Besides that, it was made various tests to validate the PI controllers implemented. These tests, consisted in varying the proportional and integral gain, to see the effect of each one and compare it with what it was expectable theoretically.
