Abstract:
On-line safety monitoring, i.e. the tasks of fault detection and diagnosis, alarm annunciation, and fault controlling, is an essential task in the operational phase of critical systems. Although current safety monitors deliver this task to some extent, the problem of effective and timely safety monitoring is still largely unresolved. In this paper, we propose a Distributed On-line Safety Monitor (DOSM) that can achieve a range of real-time safety monitoring tasks: fault detection and diagnosis, alarm annunciation and control of hazardous failures. The monitor consists of a Multi-agent Monitoring System (MaMS) operating on a Distributed Monitoring Model (DMM) that contains reference knowledge derived from off-line safety assessments, and a number of Distributed Data Structures (DDSs) that provide up-to-date sensory measurements. Guided by the knowledge contained in the DMM and real-time observations of the system provided by the DSSs, agents are hierarchically deployed and work collaboratively to integrate and deliver safety monitoring tasks, both locally at the sub-system levels and globally overseeing the overall behaviour of the system.
