Open Web Services-based Indoor Climate Control System

The paper describes an open, extensible software and hardware framework supporting all aspects of control and monitoring of a Smart Building. We designed an ‘intelligent’, real-time control system capable of both autonomous process control and interaction with human operators. The system can easily accommodate both functional extensions and a broad array of sensors and control devices. The system described below represents a clear bias towards pervasive, open-source, Internet and Web technologies and away from the proprietary or vertically specialized networks, protocols, and application frameworks typical for the current industrial automation systems. The basic goal of this research was to find out if and at what level of effort one can build a functional prototype of a Building Automation System (BAS) assembled exclusively from open-source elements. The answer we found is affirmative and the results of the experiment have the potential to affect the building-automation industry in a way similar to the impact of Linux in the domain of operating systems and of the Asterix server on the VoIP industry
