Modelisation, surveillance d’une centrale a beton par l’outil Bond Graph et validation en ligne par un systeme SCADA

Abstract

Meeting the needs for quality, quantity of the production and competition of the economic market, the industrialists tend to improve and widen their installations and become thus increasingly complex, contributing at the same time to increase the risks of failures who can occur on the operation of the plant and to decrease the environment and staff safety. In this research an approach is presented for the design of systems of supervision applied to the industrial processes, use only one tool: the bond graphs. We presented a comprehensive approach to build a system of supervision online of concrete batching and mixing plant, from the modeling, the simulation of obtained dynamic models, generation of analytic redundancy relations, detection and fault isolation, to the analysis of the placement of sensors in order to satisfy the specifications for monitoring. This work was completed by automating the concrete batching and mixing plant , creation of an interface man machine HMI, to implement the residue obtained online in a SCADA environment.
