Providing Service Composition to Cyber-Physical System for Industrial Fault Detection

This paper presents an approach to providing service composition to cyber-physical system (CPS) for industrial fault detection and vibration detection in particular. While vibration fault detection has been increasingly adopted in industrial sectors and critical infrastructure for economical and safety concerns, architectural and performance restrictions of most systems in this area impose restrictions on its wide and flexible usage. Recent research shows that it is promising to applying service-oriented architecture to developing industrial systems. We regard that enhancing CPS with services and service composition schemes in industrial vibration fault detection be feasible and promising. The architecture of our vibration fault detection CPS system, consisting of the enterprise level, gateway level and endpoint level, is integrated with various vibration detection services at relevant levels. Service composition with mapping from physical services to virtual services and to composition services is designed. It is shown by testing results that the proposed approach makes the system for real-time vibration fault detection more flexible and effective.
