The thesis may not be reproduced elsewhere without the permission of the Author. ZigBee-Based System for Remote Monitoring and Control of Switches A thesis presented in partial fulfilment of the requirements for the degree of Master of Engineering at Massey University, Albany, New Zealand. © Matthew Lyon October 2010 1 Abstract Home automation technology has existed for nearly four decades, but is nonetheless mostly absent in the average home today. The systems that do exist are often highly customised and expensive, catering to a very niche market, or overly sophisticated and complicated. Many of these also require extensive, dedicated cabling as their communications backbone and as such are only practical to install during the construction of a new house. The core aims of this project are to develop a cheap and simple home automation system that can be easily installed in new and existing houses. These aims are achieved by creating a centralised system where most of the intelligence is managed by a PC server and the end nodes are kept as simple as possible. The server is responsible for basic security, maintaining awareness of the current system state and providing the user interface. At the outer edge of the system is a ZigBee network of wall switches and, in between, a home gateway provides a protocol translation service between the two. The new, “smart” switches are designed to be entirely compatible with existing wall switches in terms of their mounting and wiring requirements, and so ZigBee is chosen to provide a reliable wireless communication channel between the end nodes and the gateway.

Tengdin’s First (and Only) Law of Telecommunications “When you see a good move, look for a better one” Emanuel Lasker, World Chess Champion from 1894 to 1921 Abstract The proliferation of the smartphones has given a considerable boost to the spread of the smart objects and the consequent creation of smart spaces. Smart objects are electronic devices that are able to work interactively and au- tonomously, usually preserving the interaction metaphor of their non-electronic counterpart. Through a network interface, they can cooperate with other objects: their strengths do not lie in their hardware, but in the capabilities to manage in- teractions among them and in the resulting orchestrated behaviour. Smart spaces are environments composed of smart devices, where they work together, producing some behaviour of benefit to the dwellers.

  • Yunjie Xiong Dissertation Submitted to the Faculty of the Virginia Polytechnic Institute and State University in Partial Fulfill
    A BIM-based Interoperability Platform in Support of Building Operation and Energy Management Yunjie Xiong Dissertation submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy In Environmental Design and Planning Georg Reichard, Chair Tanyel Bulbul Farrokh Karimi Nazila Roofigari-Esfahan Feb 21, 2020 Blacksburg, VA Keywords: Building Information Modelling (BIM), energy simulation, operational data Copyright © 2020 Yunjie Xiong A BIM-based Interoperability Platform in Support of Building Operation and Energy Management Yunjie Xiong ACADEMIC ABSTRACT Building energy efficiency is progressively becoming a crucial topic in the architecture, engineering, and construction (AEC) sector. Energy management tools have been developed to promise appropriate energy savings. Building energy simulation (BES) is a tool mainly used to analyze and compare the energy consumption of various design/operation scenarios, while building automation systems (BAS) works as another energy management tool to monitor, measure and collect operational data, all in an effort to optimize energy consumption. By integrating the energy simulated data and actual operational data, the accuracy of a building energy model can be increased while the calibrated energy model can be applied as a benchmark for guiding the operational strategies. This research predicted that building information modeling (BIM) would link BES and BAS by acting as a visual model and a database throughout the lifecycle of a building. The intent of the research was to use BIM to document energy-related information and to allow its exchange between BES and BAS. Thus, the energy-related data exchange process would be simplified, and the productive efficiency of facility management processes would increase.

  • Solutions Towards Domotic Interoperability the Contribution of the OPC Standard
    Institution for communication and information Final year project in computer science 20p Level C Spring term 2007 Solutions towards domotic interoperability The contribution of the OPC Standard Jorge Serrano Betored HS-EA-DVA-2005-001 Solutions towards domotic interoperability This final year project has been submitted by Jorge Serrano Betored to the University of Skövde, as a dissertation towards the degree of Bachelor of Science (B.Sc.) in the School of Humanities and Informatics. The project has been supervised by Anders Dahlbom. 21th May 2007 I hereby certify that all material in this dissertation which is not my own work has been identified and that no work is included for which a degree has already been conferred on me. Signature: _______________________________________________ Solutions towards domotic interoperability Jorge Serrano Betored Abstract This report presents the existence of a set of problems making the growth of the domotic field more difficult. They are mainly the lack of a common communication standard among devices and the existence of a proprietary market, where each provider focuses on developing its own devices, protocols and interfaces. There isn’t a convergence criterion in order to overcome this problem by the main domotic providers. Several studies try to overcome this problem by applying different strategies. This study analyses the main strategies followed in that field, concluding with a model that combines them. The model is based on the use of OPC and web services. Keyword: BAS, OPC, Ambient intelligence, integration, interoperation Acknowledgments The outcome of this research wouldn’t have been possible without the help and feedback provided by my supervisor Anders Dahlbom and my examiner Björn Olsson.
