DEVELOPMENT OF AN OPEN DISTRIBUTED APPROACH FOR BUILDING AUTOMATION

The demand for more efficient, reliable and safe systems has beneficed the development of new concepts for buildings automation. These features can be achieved through an effective building systems integration. However, considering that each building system has unique characteristics, the requirements specification, verification, validation and implementation of an integrated solution are complex tasks, possibly leading to an unreliable automation system. Thus, an adequate approach for treat these systems, is fundamental to manage them and to assure effectively its integration. On the other hand, treat the building system integration with characteristics of open distributed systems can provide solutions for many problems related to aspects such as flexibility, investment preservation, connectivity and interoperability. Then, in this paper Open Distributed Processing - ODP is introduced as a general framework upon which open distributed system can be modeled through the viewpoint concept and the use of an object oriented language (Unified Modeling Language UML). The Petri net (PN) is also considered because it could provide a effective model analysis. In this context, the purpose of this work is to introduce an open distributed approach for building automation based on the merging of ODP framework, UML and PN.
