RESUMO

Technological advances in recent decades have motivated the development of intelligent buildings, aimed at creating environments more productive for the occupants, economically advantageous for the owners and environmentally correct. New ways of interaction between users and the buildings systems are emerging from these kinds of systems, which are not adequately treated by conventional modeling techniques. In this sense, it is necessary the study of new approaches which address these new functionalities. Thus, this work presents a proposal for a systematic approach to model and simulate the control system of the intelligent buildings. The control system is considered to be a discrete event system, where the communication between the devices that integrate it is oriented by means of asynchronous messages exchange. This approach uses the colored Petri nets in order to specify the functionalities of the building system and their devices interactions. The approach provides a structured procedure to develop models that facilitate the algorithm specification of the control system. In order to verify the main characteristics of the proposed procedure, it is presented an example that is a control system that integrates a distributed telephony system and a surveillance building system. The approach proposed enabled the identification of the main functionalities and interactions of the intelligent devices constituting the control system. The achievement of this thesis contributes to the development of new approaches to develop heterarchical control system architectures. This kind of system architectures is constituted by collaborative intelligent devices that have a high degree of autonomy.
