Description
Summary:The growing complexity of systems and the need for executing large projects have led to the development of complex flexible manufacturing systems (FMS) demanding specific control-monitoring architectures. The problem of failure occurrence tends to increase according to this complexity leading to time-consuming tasks as the isolation and repairing. In this context, the maintenance integration into a control-monitoring system becomes an important issue. It results in improvement of the system functionality in terms of availability, efficiency, productivity and quality. This paper proposes a control-monitoring-maintenance architecture (CMM) for FMS based on Petri nets with objects (PNO). This supervision framework is based on a modular and hierarchic model structured in CMM modules. The integration is based on a development methodology in which the maintenance aspects and policies are taken into account from the conception (modelling) stage. These efforts acts as a basis for the control architecture of a robot-driven flexible cell, connected to the Ethernet-TCP/IP
