Sistema de Supervisao Tolerante a Falhas (Fault Tolerant Supervision System)

摘要

This paper proposes the incorporation of fault tolerant techniques in a process control oriented real time system to be applied in activities of supervision. These techniques should provide a higher availability of the Supervision System if simple fault of the hardware should occur. A basic architecture with dual redundancy is proposed. With regard to the software the backward-error-recovery technique is explored by establishing recovery points under the control of the supervision applicatives.
