Previous issue date: 2015-01-26 / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico - CNPq / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Este trabalho apresenta o desenvolvimento de um sistema de detec??o e
diagn?stico de falhas em sensores de campo com corre??o do sinal com falhas
dinamicamente, onde esse sistema ? baseado no conceito de agentes inteligentes, em
uma arquitetura de multiagentes. O sistema tem como ambiente de atua??o a rede
industrial Foundation Fieldbus.
Para realizar a detec??o e o diagn?stico das falhas, s?o utilizados os algoritmos
de redes neurais artificiais e l?gica fuzzy (atuando como classificador fuzzy), os quais
s?o embarcados na rede industrial Foundation Fieldbus.
Al?m disso, de forma a atuar junto ao sistema de detec??o, diagn?stico e
corre??o de falhas foi desenvolvido um software que realiza o monitoramento e a
supervis?o do mesmo, onde foi instanciado um agente se comunicando com a rede
industrial. Os demais agentes s?o instanciados nos blocos funcionais da rede industrial. / This work performs the development of a system of detection and diagnosis of
faults in field sensors with dynamically signal correction, which this system is based on
the concept of intelligent agents, using architecture of multagents. The system operates
in environment industrial network Foundation Fieldbus.
To perform the detection and diagnosis of failures are used the algorithms of
neural networks and fuzzy logic (acting like a fuzzy classifier), which are embedded in
industrial network Foundation Fieldbus.
Furthermore, in order to work with the system of detection, diagnosis and
correction of failures was developed a software to perform the monitoring and
supervision of the system, which was instantiated an agent communicating with the
industrial network. The other agents are instantiated on the functional blocks of
industrial network.
