    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
    (Massey University, 2010) Lyon, Matthew
    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. Development of the system is undertaken in three stages; design of the server software (including the user interface and server processes), design of the home gateway embedded software, and design of the hardware and embedded software of the switches. The end result is an effective, entry-level system that provides the benefits of remote management without the need for a costly or complex infrastructure.

    Intelligent medical device integration with real time operating system : a thesis submitted to the School of Engineering in partial fulfilment of the requirements for the degree of Master of Engineering, Department of Electronics and Computer Syetem [i.e. Systems] Engineering at Massey University, [Albany], New Zealand
    (Massey University, 2009) Jan, Zaid
    Many commercial devices now being produced have the ability to be remotely monitored and controlled. This thesis aims to develop a generic platform that can easily be extended to interface with many different kinds of devices for remote monitoring and control via a TCP/IP connection. The deployment will be concentrated on Medical devices but can be extended to all serial device interfaces. The hardware to be used in the development of this platform is an ARM Cortex M3 based Micro-Controller board which has to be designed to meet the requirement set by the Precept Health the founder of this platform. The design was conducted at Massey University in collaboration with senior engineer from the company. The main task in achieving the aim was the development of the necessary software layers to implement remote monitoring and control. The eCosCentric real-time embedded operating system was used to form a generic base for developing applications to monitor and control specific devices. The majority of the work involved in this project was the deployment of the operating system to the Micro-Controller. During the development process, several hardware issues were discovered with the Ethernet interface and were corrected. Using the generic platform, an application was developed to allow the reading of Bi-Directional pass through a communication protocol from 4 isolated serial input channels, to an Ethernet channel using TCP protocol.
