Résumé des résultats (Abstract) (Allemand)

Vibro-Meter¿s current product line, ¿VM600¿ is based on a centralized architecture. A recent market study has shown big potential in low to mid size (5 to 50 MW) rotating machinery. Vibro-Meter wants to address this market with a distributed measuring system offering similar capability as the centralized system yet with increased flexibility and improved cost efficiency. A feasibility study indicated that although a standard network protocol may be used as a basis for the distributed measuring system several complementary technologies must be developed in order to be able to use this protocol for instrumentation applications: ¿ Real-time error correction en- and de-coding for high accuracy TACHO signals ¿ Fairness scheduling in real-time switch for bulk data transfer ¿ Optimised local addressing scheme for online-configuration and plug-and-play like operation ¿ Strategy for handling loss of synchronisation as well as media redundancy ¿ Development and integration of safety frames/protocol for mission-critical data transfer
