Development of an Embedded Smart Home System

Smart home systems are expected to become key research area for ubiquitous and embedded system computing in coming years. In this thesis, a new scheme in smart home systems technology using embedded system for providing intelligent control of home appliances is proposed. An embedded system act as protocol glue that incorporates wired and wireless option such as Short Message Service (SMS) router with wireless local area network (WI-FI) for intelligent automation and higher speed of home appliances connectivity. The system is implemented in 2 tier models. First-tier model consist of incorporated design of SMS Router and Wireless Access Point. Wireless local area network (WI-FI) is selected as mechanism due to its transmission range within 100m which suits the smart home requirement for automation and control, justifies the Personal Area Network (PAN) for mobile device connectivity. Second tier model consist of remote application server systems, which cater a conceptual model between embedded hardware and software integration of appliances in smart home. This interface model will be between in house networks and external communication environment, whereas embedded system acts as storage media and server for information interchange between systems especially with mobile devices within a smart home. Embedded system sits at the core of the home network, acts as residential gateway and enables bi-directional communication and data transfer channel among networked appliances in the home and across the Internet. On the other hand, client-side application provides a user-friendly Graphic User Interface (GUI) to enhance the usability of the system. The proposed embedded system has been implemented and verified that the system can be a core device for smart home environment functionality

Novel Approach for User-Friendly Home Automation System on One Touch

The home Automation has been showing from last 10 to 15 years its far reaching and crucial importance in domestic and industrial world. The paper represents a research and development of an embedded project of Home Automation. There are many "already existing” home automation system which are also based on the "Central Unit" which controls everything but are quite expensive and less user-friendly. The main purpose of this project is to reduce the cost of the system providing a better interface which user-friendly as well. The basic idea of this the system is to have a server as the central controller which has multiple clients and is connected to the mobile device which is at remote location which sends the query to access the home devices and is also connected to circuitry present at the home using wireless connection(Zigbee Interface). In the case the system consist of the replicas of the home which is to be automated. It also has an asset of a Real time System DOI: 10.17762/ijritcc2321-8169.15014

Remote Control and Monitoring of Smart Home Facilities via Smartphone with Wi-Fly

Due to the widespread ownership of smartphone devices, the application of mobile technologies to enhance the monitoring and control of smart home facilities has attracted much academic attention. This study indicates that tools already in the possession of the end user can be a significant part of the specific context-aware system in the smart home. The behaviour of the system in the context of existing systems will reflect the intention of the client. This model system offers a diverse architectural concept for Wireless Sensor Actuator Mobile Computing in a Smart Home (WiSAMCinSH) and consists of sensors and actuators in various communication channels, with different capacities, paradigms, costs and degree of communication reliability. This paper focuses on the utilization of end users’ smartphone applications to control home devices, and to enable monitoring of the context-aware environment in the smart home to fulfil the needs of the ageing population. It investigates the application of an iPhone to supervise smart home monitoring and control electrical devices, and through this approach, after initial setup of the mobile application, a user can control devices in the smart home from different locations and over various distances

Evaluating Thread protocol in the framework of Matter

Internet of Things is a technology which produced one of the biggest, and with most impact on the society, change in connectivity and automation solutions. It has a lot of new features and advantages, but also has its constraints. For this purpose, many standard have been developed, and IoT solutions designed. A Home Automation system is an application of IoT. It consist of IP-enabled embedded devices connected to the Internet using IPv6.The technology improved when IETF designed 6LoWPAN as a interface to link IPv6 to IEEE 802.15.4, a low-power wireless network standard Untill now, the IoT market is very dispersed with many solutions based in different standards, which make them incompatible between themselves. Appart from that, Home Automation technologies and solutions do not meet the requirements of low power, IP-based, security and friendly use. In order to profit from, and accelerate it, the IoT technology emergence, a unification of the standards used and the requirements needed by the different IoT solutions must be designed. The goal of this thesis was to study a new Home Automation standard called Matter. Matter is an application layer standard which aims to simplify the development for manufacturers and increase compatibility for the consumers, enabling communication across smart home devices, mobile apps, and cloud services. As Matter was to be released in the summer of 2021 but was delayed, instead of that, the Thread architecture has been studied. Thread is, with Wi-Fi, the core of the operational communications supported by Matter. Thread is a simplified, IPv6-based mesh networking architecture developed for efficient communication between energy-constrained devices around the home. As Thread is a royalty-free but closed-documentation standard, Nest Labs developed an open source implementation Called OpenThread. This study is composed by an overview of the architecture, a detailed explanation of each layer of the stack, and a implementation of the network through OpenThread. Furthermore, some test will be evaluated to provide to the reader an introduction to some of the Thread functionalities, specially related with routing

Intelligent distributed module for local control of lighting and electrical outlets in a home

This article proposes a control of lighting and electrical loads, suitable for smart homes, using embedded systems with low-cost wireless communication modules. The system is based on a distributed intelligent home automation architecture, to work autonomously or interconnect wirelessly to a larger system. It has a set of sensors that allow you to ration the use of electricity through automatic switching off the lights or electrical devices, allowing the lighting to be regulated. It has several modules that communicate to a central node wirelessly, and an interface based on a mobile application. UML and Petri Nets were used for the projection, modelling and validation of the system, its implementation was developed in C/C ++ language for 32-bit microcontrollers. Tests of the prototype showed stable behavior, fast communications and sufficient coverage for a single-family house, whose performance is higher to other similar works found in the scientific community

Remote control of devices using an 8-bit embedded XML & dynamic web-server in a SmartHouse environment : a thesis presented in partial fulfilment of the requirements for the degree of Master of Engineering in Computer Systems Engineering at Massey University

This paper focuses on an Embedded System known as "TCP/IC" and its role in the "house of the future" - the SmartHouse. Overall, the aim of the TCP/IC was to design a device which could interact with a user (or AI control system) and allow for the control of various attached peripherals remotely. Although such a device could well be used as a standalone device to aid in home-automation, this paper focuses on its use in a SmartHouse environment - one where a number of these devices are networked and controlled by a central AI. The different technologies and protocols involved in the implementation of the TCP/IC, along with its two primary interfaces, namely HTML (used for user interaction) and XML (used for machine interaction) are also discussed. The reader will also be introduced to Embedded Systems and the various design principles involved in the creation of quality Embedded Systems. Core-concepts of home-automation and its logical extension, the SmartHouse are also covered in detail. Various additional interfaces (e.g. Web, XML, custom-formatted text) are also discussed and compared, as are the result of my work and some ideas for future implementations

Desenvolvimento de Aplicação para Controle de Dispositivos via Rádio Frequência

TCC(graduação) - Universidade Federal de Santa Catarina. Centro Tecnológico. Engenharia de Controle e Automação.O conceito de automação residencial tem mudado ao longo dos anos, incorporando uma gama de possibilidades práticas e econômicas que utilizam a automação, desde a básica até a mais abrangente, em sistemas de integração para diversos ambientes. O objetivo é criar um ambiente prático, confortável, valorizado e seguro, de acordo com os interesses dos usuários. Os dispositivos móveis também foram incorporados como soluções de automação residencial, na maioria das vezes substituindo os diversos controles remotos. A Cheesecake Labs, empresa situada em Florianópolis, SC, foi contratada para o desenvolvimento de um software que tem como objetivo comunicar um aplicativo móvel com uma placa que envia sinais de rádio frequência para controlar dispositivos comuns encontrados em residências, principalmente nos Estados Unidos, como ventiladores de teto ou portões de garagens. Este projeto, denominado Bond, deve habilitar o usuário a configurar comandos de diferentes controles, permitindo que o morador substitua todos os controles remotos da casa — incluindo aqueles que emitem sinais de rádio frequência — por um aplicativo móvel. Primeiramente foram feitas reuniões de escopo com a empresa contratante Altus-PCB, de Nova Jérsei – EUA. Em seguida, iniciaram as etapas de design do aplicativo na plataforma iOS/iPad, da Apple Inc. Com posse das telas do aplicativo, iniciaram os esforços para o desenvolvimento do software do aplicativo móvel, desenvolvimento do sistema de back-end em sistema embarcado, descoberta automática de dispositivos via Bonjour, comunicação via REST API entre aplicativo e back-end hospedado em sistema embarcado e, por fim, comunicação serial entre sistema embarcado e placa de rádio frequência. É importante destacar que a incorporação de controles via rádio frequência e a possibilidade de programação desses pelo próprio usuário, representa uma inovação para os sistemas atuais de automação residencial.The concept of home automation has been changing through the years, adding a variety of practical and economics benefits, in different levels, allowed by the home device’s integrations. The goal is to offer comfortable, intelligent, safe and valuable environment according to people desires. The mobile devices are also part of the new era of home automation and are introduced, most of the time, as an alternative to the standard remote controls. The company Cheesecake Labs, from Florianopolis, SC, was contracted to develop the software in order to communicate a mobile application with a radio frequency board that sends signals to control home devices, like ceiling fans and garage doors. The project, called Bond, aims to allow the user to configure different commands, enabling people to replace their common home controls with the Bond mobile application and radio frequency board. Firstly, scope definition meetings were done to better understand the client’s needs. Secondly, the design of the mobile application was developed. Once the mock-ups were completed, the development of the mobile application was done, followed by the back-end hosted on the embedded system, automatic discovery of devices through Bonjour, REST API communication between mobile application and embedded system, and, finally, the serial communication between the embedded system and radio frequency board. It’s important to mention that adding radio frequency controlled devices to the home automation scope represents an advance on the current home automation technologies, since most of the controlled devices works with infrared or Wi-Fi signals
