Actualmente a área da domótica (automação de casas e edifícios) encontra-se em franca
expansão, com principal relevância nos países mais desenvolvidos, com um crescimento de
mercado de mais de 10% ao ano.
Existem inúmeras razoes para a crescente implantação da domótica em edifícios, entre as quais
a maior eficiência energética, o aumento da segurança e a redução do custo de aquisição das
tecnologias. No que diz respeito as habitações particulares, acrescenta-se essencialmente o
aumento do conforto devido ao grau de automação trazido pela domótica.
Apesar da domótica não ser uma área cientifico-tecnológica recente, a rápida evolução das
tecnologias associadas, nomeadamente a nível das redes de comunicação com e sem fios, foi
uma das razoes fundamentais para a elaboração desta Tese. Acresce o facto de o candidato
estar actualmente envolvido profissionalmente na área, pelo qual esta Tese assume uma
particular importância.
Realizou-se um estudo comparativo das tecnologias de domótica mais relevantes, escolhidas
quer pelas suas características técnicas quer pela sua implantação de mercado e potencial
futuro - KNX/EIB, LonWorks, HomePlug, ZigBee e Z-Wave. Destas, comprovou-se que as
duas primeiras são aquelas que, actualmente, tem maior adequabilidade para serem aplicadas
em projectos de domótica.
Foi por isso efectuado um estudo mais elaborado das tecnologias LonWorks e KNX/EIB,
incluindo a forma pratica de instalação/programação, a elaboração de dois demonstradores e de
dois projectos (de acordo com um caderno de encargos real), usando as duas tecnologias.
Concluiu-se que a tecnologia LonWorks apresenta vantagens no que respeita a escalabilidade
(dimensão) dos sistemas. Em termos futuros, prevê-se a necessidade da interoperabilidade
entre os nos/redes cablados (tradicionais) com nos/redes sem fio, seguindo a tendência para os
ambientes inteligentes (“ambient intelligence/assisted living”, “smart spaces”, “ubiquitous
computing).
Nowadays, the Domotics area (residence and building automation) is in large expansion, mainly in the most developed countries, with a market growth of over 10% a year. There are several reasons to justify the growing of the use of domotics in buildings, such as the improvement of energy’s efficiency, the increase of safety and the decrease of technology’s costs. Concerning family homes, we may add to these aspects the augment of confort, due to the automation’s level achieved with domotics. Although domotics is not a recent scientific-technological area, the fast evolution of conjoint technologies, such as wire or wireless communication nets, was one of the main reasons for the elaboration of this thesis. The fact that the candidate is at the present time professionally connected to the area is also a reason for this dissertation’s subject, which grants it a major relevance. One focus was a comparative research of the most important domotics technologies, chosen according to their technical characteristics and their implementation on present and future’s market – KNX/EIB, Lonworks, HomePlug, ZigBee and Z-Wave. Among these, the first two are the ones that proved themselves to be more suitable for domotics project application. This is why a deeply elaborated research was made, focusing on Lonworks and KNX/EIB technologies, including the practicability of installation and programming, the built of two demonstrators and two projects (in compliance with a real working order), using both technologies. We came to the conclusion that Lonworks’s technology grants more advantages concerning the range and dimension of the systems. In the future, we can predict the need of interaction and operability between us/cabled nets (common) and us/wireless nets, which leads to the “ambient intelligence/assisted living”, the “smart places”, or “ubiquitous computing”.
