Design and implementation of a home automation system with an interactive application for digital television based on the ginga middleware

Abstract:

In this work we present “DomoiTV”, a home automation system and its communication protocol with a graphic interface for the Brazilian digital terrestrial television standard ISDB-Tb. This project is divided into three main phases, the design and implementation of the home automation system, the development of the graphic interface for DTT and the communication protocol between these two areas. For the automation phase, six areas are covered: intrusion alarms, technical alarms, lighting control, blinds and shades control, access to cameras, and pre-programmed scenarios. To meet the requirements of these six areas, a controller with different sensors and actuators are installed providing a safe, comfortable and controlled environment. The user interface, designed as an interactive TV application based on the Ginga middleware, is the way to represent the automation devices installed, therefore the user can visualize the status of each sensor and take action on its actuators. In addition, a mobile user application was implemented to provide interoperability and usability in multiple devices. The communication protocol is developed in order to manage data sent from the application through TCP communication; and by means of a translator the information is bkp_redirected to a Real-Time cloud database, where the controller has access to complete the communication between both parties. Testing of operation and Start-up of the automation system is carried out, in addition to the application usability tests on several devices. The final system resulted in an integrated, robust and reliable system in terms of operation; and friendly and intuitive to the user.
