Utveckling av ett öppet Home Automation-protokoll för användning över IP-nätverk / Development of an open Home Automation protocol for use over IP networks

Johnsson, Kim, Turfors, Christoffer, Ericson, Eric January 2010 (has links)
<p>Detta arbete tar upp utvecklingen av ett nytt protokoll för användning inom Home Automation över IP-nätverk, med stor vikt på flexibilitet och enkelhet.

Metoden vi valde för att utveckla protokollet är en generell designmetod där vi efter granskningen av tidigare protokoll tar fram ett antal punkter som det nya protokollet skall uppnå. Det visade sig dock vara problematiskt att få fram svar om vissa protokoll så vi frångick metoden genom att istället utveckla protokollet utefter ett antal olika scenarion som det bör kunna hantera.</p><p>Resultatet av arbetet är ett protokoll som uppfyllde nästan alla mål vi satt upp för det.

Tecnologia assistiva para detecção de quedas : desenvolvimento de sensor vestível integrado ao sistema de casa inteligente

Torres, Guilherme Gerzson January 2018 (has links)
O uso de tecnologias assistivas objetivando proporcionar melhor qualidade de vida a idosos está em franca ascensão. Uma das linhas de pesquisa nessa área é o uso de dispositivos para detecção de quedas de idosos, um problema cuja ocorrência é cada vez maior devido a diversos fatores, incluindo maior longevidade, maior número de pessoas vivendo sozinhas na velhice, entre outros. Este trabalho apresenta o desenvolvimento de um dispositivo vestível, um nó sensor de redes de sensores sem fio de ultra-baixo consumo. Também descreve a expansão de um sistema KNX, ao qual o dispositivo é integrado. O dispositivo é capaz de identificar quedas, auxiliando no monitoramento de idosos e, por sua vez, aumentando a segurança dos mesmos. O monitoramento é realizado através de acelerômetro e giroscópio de 3 eixos, acoplados ao peito do usuário, capaz de detectar quedas através de um algoritmo de análise de limites determinados a partir da fusão dos dados dos sensores. O sensor vestível utiliza tecnologia EnOcean, que propicia conexão sem fio com um sistema de automação de casas inteligentes, de acordo com a norma KNX, através da plataforma Home Assistant. Telegramas de alarmes são automaticamente enviados no caso de detecção de quedas, e acionam um atuador pertencente ao sistema KNX. Além de validar a tecnologia EnOcean para uso em dispositivos vestíveis, o protótipo desenvolvido não indicou nenhum falso positivo através de testes realizados com dois usuários de características corporais diferentes, onde foram reproduzidos 100 vezes cada um dos oito tipos de movimentos (quatro movimentos de quedas e quatro de não quedas). Os testes realizados com o dispositivo revelaram sensibilidade e de especificidade de até 96% e 100%, respectivamente. / The use of assistive technologies to provide quality of life for elderly is increasing. One of the research lines of this area is the use of devices for fall detection, which is an increasing problem due to many factors, including greater longevity, more elders living alone, among others. This work presents the development of a wearable device, a sensor node for ultra-low power networks. Also, describes the expansion of a KNX system, which the device is integrated. The device is able to detect falls which can aid the monitoring of the elderly people and improve security. The monitoring is done through a 3-axis accelerometer and gyroscope attached on the user’s chest. The fall detection is done by a threshold algorithm based on data fusion of the sensors. The wearable sensor is an EnOcean node, which includes a wireless connection with a smart home system, according to the KNX standard, through the Home Assistant platform. Alarm telegrams are automatically sent in case of fall detection, and fires an actuator that is part of the KNX system to alarm. In addition to validating the EnOcean’s Technology for use on wearable devices, the developed prototype didn’t indicated any false positives through tests performed with two users of different body characteristics, where each of the eight types of movements (four movements of falls and four of non-falls) were reproduced 100 times. The tests done with the device revealed sensitivity and specificity of up to 96% and 100%, respectively.

The Smart Home From a Security Perspective

Christensson, Daniel, Eriksson, Emelie January 2019 (has links)
Based on the fact that many electronic devices are digitalized in our world in order to facilitate our lives, there is a large potential for development in the home. Smart Home solutions are giving us the opportunity to control and manage for example alarms, electricity and surveillance but the technology's rapid improvement paves the way for issues related to security. The objectives for this work will bring up common communication technologies, security and vulnerabilities in the context of a Smart Home and what could be done for future work. In order to investigate the objectives, a literature study has been conducted together with an experiment. The experiment result exploits a weakness in a common Smart Home technology used in the network enable devices in the form of threats and vulnerabilities. In order to mitigate and minimize threats and vulnerabilities one conclusion is that a security policy could be produced. This security policy should provide the user with good practice of how to manage security in order to mitigate vulnerabilities and threats within the Smart Home.

Realizace demonstrativního panelu inteligentní elektroinstalace KNX / Development of KNX installation demo-board

Mitrenga, Michal January 2021 (has links)
The aim of this diploma thesis is to compile a demonstration panel as an example of the functions of intelligent electrical installation KNX. One of the advantages of this system bus is the ability to use devices from multiple manufacturers. A total of 20 devices from 12 different manufacturers are used in this work. The work begins with an explanation of the principle on which the KNX system bus works, followed by a description of the equipment used and the electrical connection of the switchboard according to the wiring diagram. Next, how the whole panel was revived is described. The next chapter contains a detailed description of device programming in ETS, ie setting parameters for individual devices and assigning group addresses. The last chapter deals with visualization and remote control. It explains how a communication channel was created to connect the panel to a server from FlowBox. Using the web interface on this server, a visualization was created, which can be used to remotely control the entire panel from anywhere.
