The building automation system is capable of controlling all the electronic devices of the building from one central unit. The integrated systems like this one have a steady demand, because there are more and more intelligent devices around us and there are respectively cheap and high performance microcontrollers at service to establish such a system.
The object I proposed in my thesis this semester was planning and making an easier building automation system. This simple embedded system could contain one central unit and one or more peripheries. It uses wireless data transfer to communicate between the units.
In the first section of my thesis I briefly delineate my ambitions and tersely demonstrate the wanted system.
In the second section I partly plan the system’s architecture, choose the proper mode of data transfer between the central unit and the PC and between the central unit and the peripheries. I deal with microcontroller based embedded systems, sub GHz ISM banded radio data transfer and the USB standard in details. Above all I mention the other possible data transfer possibilities.
In the third section I write about the hardware establishment of the system. I document the selection of the specific components, circuit diagram and printed circuit.
In the fourth section I document the software establishment of the central unit and one periphery.
In the fifth section I summarize what was I able to establish and what are the possibilities of the future improvement of the system.
