Title in Portuguese
Modelagem de sistemas de proteção técnica contra incêndio em edifícios inteligentes através de rede de Petri.
Keywords in Portuguese
Edifício inteligente
Rede de Petri
Sistema de detecção e combate a incêndios
Sistemas a eventos discretos
Abstract in Portuguese
O sistema de proteção técnica contra incêndio (SPTCI) é um dos principais sistemas que compõem o edifício inteligente (EI), pois a eficiência do seu funcionamento afeta diretamente a segurança das pessoas e o patrimônio do prédio. O SPTCI é composto de diferentes dispositivos, estratégias de controle e atua segundo legislação específica. Devido à complexidade do SPTCI, torna-se fundamental uma modelagem adequada que permita verificar a dinâmica do sistema e sua relação com outros sistemas prediais. Neste contexto, este trabalho propõe um procedimento para a modelagem e análise de estratégias de controle para o SPTCI, integrado com outros sistemas prediais dentro do contexto de EI. A abordagem considerada para este propósito baseia-se na teoria dos sistemas a eventos discretos, na aplicação de técnicas derivadas da rede de Petri e em técnicas de análise através de simulação discreta. Com esta abordagem são desenvolvidos modelos do sistema de controle do SPTCI onde é considerada a sua relação com outros sistemas prediais. Particularmente, explora-se as extensões da rede de Petri como as técnicas Production Flow Schema e Mark Flow Graph. Um estudo de caso é apresentado para ilustrar as principais características deste procedimento.

Abstract in English
From the point of view of property damage and personal security, the fire protection system (FPS) is one of the most important systems in an intelligent building (IB). The FPS is composed of several devices and control strategies. Furthermore, it must act in accordance with specific laws. As a consequence the design of FPSs is a complex task and it is very important to provide an adequate model that supports the verification of the FPS dynamics and its integration with others building systems, facilitating its test and validation. In this context, this work proposes a procedure to model in a systematic and rational way a FPS in the IB context. Considering the nature of the structure and processes of FPS the approach is based on the discrete event dynamic system theory and the application of the Petri net. Then, the models the FPS control system and the controlled plant must include its integration with other building systems. Particularly, it explores Petri net extensions such as Production Flow Schema and Mark Flow Graph techniques. Through an example it is illustrated the main aspects of the proposed procedure.
