Honours Engineering Thesis DALI Building Automation, BMS Integration and Communication Using Modbus SCHOOL OF ENGINEERING AND INFORMATION TECHNOLOGY Honours Engineering Thesis DALI Building Automation, BMS Integration and Communication using Modbus By Robert Pezzaniti Supervisor Associate Professor Graeme Cole A thesis submitted to Murdoch University School of Engineering and Information Technology to fulfil the requirements for the Bachelor of Engineering Honours Degree in the discipline of Industrial Computer Systems Engineering & Electrical Power Engineering Murdoch University, Western Australia, 2017 © Murdoch University & Robert Pezzaniti 2017 Author’s Declaration I declare that this thesis is my own account of my research and contains as its main content work which has not previously been submitted for a degree at any tertiary education institution. X Robert Pezzaniti Abstract The protocol of Digital Addressable Lighting Interface (DALI) was established in the early 1990s by a conglomerate of lighting product manufacturers to replace the original 0-10 V lighting control systems. It was designed as an open standard substitute to Digital Signal Interface (DSI), on which its structure is based [1]. The scope of this project was to control the lighting in the Murdoch University, South Street Campus, Western Australia by using a chosen controller to connect those modules to the chosen Schneider Enterprise/Automation server in the most efficient manner. This control would effectively allow Murdoch University to save more money on power, diminishing the impact on the environment due to power usage. This also gives a better suited environment to staff and students where lighting levels can be set at optimum levels defined by The Commission for Occupational Safety and Health [2] to reduce fatigue and glare. To achieve this control a microcontroller was used to sit as an intermediate path between the DALI devices and the Schneider BMS (Building Management System) that runs and monitors Murdoch’s South Street Campus by using Modbus. Research was carried out in multiple fields (specifically cost, reliability, features and complexity) to investigate how other similar technologies accomplished this solution, and an ongoing study of the field of interest allowed for a more in-depth review of the current technologies advantages and drawbacks. The research was then used to verify the design work needed for the system and create the basics of the system, upon implementation of all designs and features, control of Murdoch University’s Library was achieved. iii Acknowledgements Firstly, I’d like to say a big thank you to my supervisor Associate Professor Graeme Cole. If it wasn’t for your guidance over the past few years, showing me how to teach myself and be an engineer, I never would have made it here. I don’t think I could ever repay you for that (I’ll try though). Thank you to Mr Iafeta “Jeff” Laava, Mr Will Stirling, Mr Graeme Malzer and Dr Gareth Lee for making time for me and supporting me throughout this process. I’m sorry I popped up out of the blue all the time, and I’m grateful you all facilitated me to the best of your abilities. To my friends still at university and those who have gone, you have made this experience the most memorable and enjoyable time of my life. Thank you for putting up with my antics and for easing the stress with lots of laughter and great times. There are certain people who have made such an impact on my life that I hope we can always keep in contact (you know who you are), especially because at times we spent many days and nights straight together, and that tells you who a person really is. Thank you to my family, for understanding over the long nights why I couldn’t be around, dealing with my moods and my coming and going at all hours of the day and night. Thank you so much Mum and Dad for bringing me up right and giving me the determination to never give up. I love you guys so much and hope I can finally help you guys out. And lastly thank you Naszira Umana-Olson for constantly dealing with me, I know it’s been a long time coming but the support you’ve given me over the years at university massively helped me finish this course. For this I am eternally grateful for the happiness, laughter, joy and love you’ve brought me while I worked night and day to get here. I’m not sure how I would’ve done it without you. Also, I’m an engineer now, prepare to hear that a lot more often. And thank you Murdoch University, you were the right choice all those years ago. v Table of Contents Author’s Declaration

    DESIGN, ANALYSIS AND EXPERIMENTAL VERIFICATION OF A SMART POWER SOCKET by Rohit Seshadri A thesis submitted to the faculty of The University of North Carolina at Charlotte in partial fulfillment of the requirements for the degree of Master of Science in Electrical Engineering Charlotte 2016 Approved by: ______________________________ Dr. Madhav Manjrekar ______________________________ Dr. Arindam Mukherjee ____________________________ Dr. Valentina Cecchi ii ©2016 Rohit Seshadri ALL RIGHTS RESERVED iii ABSTRACT ROHIT SESHADRI. Design, analysis and experimental verification of a smart power socket. (Under the direction of Dr. MADHAV MANJREKAR) Demand for smart homes and smart devices has witnessed a consistent rise in the past decade. Home automation in residential buildings provides residents additional comfort of controlling their devices at the touch of a button. The concept of automated homes dates back to early 1930s but it has grown in consumer acceptance in this internet age courtesy of better sensors and seamless connectivity. Although smart devices and smart home technologies offer great convince to users, they tend to be expensive and are have to be first replaced with existing devices which requires high investments. There are alternatives to make existing appliances smart by adding adapters but these adapters too tend to be expensive. Proposed smart socket ecosystem uses an existing home power distribution network for communications. This power socket uses power lines to transfer control commands and measurement data. The hardware consists of a low cost microcontroller to measure and control power characteristics of electric appliances. A Raspberry Pi like credit card sized computer acts as a server and serves as a communication hub for the entire socket ecosystem.

    Eclairage à graduation par jreihem » Ven 14 Oct 2016 18:03 Bonjour les experts, Je m’interroge sur l’éclairage à graduation (variation de la luminosité d’un luminaire via un BP). Je connais la variation « dimmable » (1-10 V) et je ne connais pas bien la variation « Dali ». Quelle est différence entre de ces 2 types de variations ? Et pouvez-vous me citer les 4 systèmes de graduations les plus utilisées en ce moment, les plus en « vogue », s'il vous plaît. Dans le cas d’une variation avec de la LED, est-ce que plusieurs systèmes de variations peuvent fonctionner avec le même type de LED ? Par avance, merci pour vos réponses et je vous souhaite un bon WE. Tous les systèmes de gradation connus sont en principe également utilisables pour l’éclairage à LED : • DALI • 1-10 V (application moins fréquente dans l’éclairage à LED) • TouchDim • DMX (moins appliqué pour l’éclairage, plutôt utilisé dans le monde du théâtre). comparaison 1-10 V analogique et DALI numérique comparaison DALI-1 10V_BE gradables pour tubes fluorescents et lampes fluocompactes | OSRAM Comparaison numérique/analogique : fonctions et connexions DALI 1...10V C ommande d’entrée isolée C ommande d’entrée isolée Deux fils (sans polarité) Deux fils (avec polarité +/-) C ourbe de gradation visuelle linéaire (= logarithmique), Courbe de gradation du flux correspond à la sensibilité de l’oeil humain linéaire Adressage possible : Individuellement (max. 64 adresses) Non adressable En groupe (max. 16) Câblage par groupe nécessaire Tous ensemble -> pas de câblage d’après les groupes Mémorisation de scènes (max.

Advancements in information and communications technology (ICT) have revolutionized energy management in industrial facilities and large commercial buildings. As ICT costs decrease and capabilities increase, buildings automation and energy management features are transforming the small-medium commercial and residential buildings sectors. A vision is emerging of a connected world in which building equipment and systems coordinate with each other to efficiently meet their owners’ and occupants’ needs and buildings regularly transact business with other buildings and service providers (e.g., gas and electric service providers). However, while the technology to support this collaboration has been demonstrated at various degrees of maturity, the integration frameworks and ecosystems of products that support the ability to easily install, maintain, and evolve building systems and their equipment components are struggling to nurture the fledging business propositions of their proponents. Through its Building Technologies Office (BTO), the United States Department of Energy’s Office of Energy Efficiency and Renewable Energy (DOE-EERE) is sponsoring an effort to advance interoperability for the integration of intelligent buildings equipment and automation systems, understanding the importance of integration frameworks and product ecosystems to this cause.

  • Clipsal C-Bus Product Guide
    Clipsal C-Bus Product Guide Make the most of your energySM Introduction to C-Bus The Clipsal C-Bus system is a microprocessor based wiring system used to control lighting and other electrical devices. From ON/OFF control of a lighting circuit to analogue type control, such as dimming electronic fluorescent ballasts, C-Bus can control and automate virtually any type of electrical load. C-Bus information is held within individual C-Bus units rather than one central point. This ensures optimum communications speed and reliability. To ensure fast and reliable operation, each device has its own built-in microprocessor, which can be individually programmed via ‘point and click’ PC-based software, or via ‘Learn Mode’ which doesn’t require a PC. While a computer is unnecessary for normal C-Bus operation, C-Bus PC-based control and management software is available and provides additional flexibility to clients requiring this type of control. Clipsal C-Bus is suitable for a wide range of applications. Commercial Lighting Control for cost and energy saving Mood Lighting in Restaurants and Retail Outlets to create a relaxed ambiance Standalone Room Control for Conference Rooms & Home Theatres Residential Home Control for security, lighting, comfort & convenience C-Bus Network Design Considerations • Up to 1000m of C-Bus Cat. 5 UTP cable may be connected to a single C-Bus network • Up to 100 C-Bus units may be connected to a single C-Bus network • Where more than 1km and/or 100 standard C-Bus units are required, two or more networks can be created and linked with C-Bus Network Bridge and/or C-Bus Ethernet Interface Units • Maximum number of networks in one installation is 255 (this limitation does not apply if a C-Bus Ethernet interface is utilised, the system size is then limited to IP addressing only) • Maximum number of networks connected in series to the local network via Network Bridges is seven (i.e.
