A Demonstration System for a New Time-Triggered Sensor Network, Based on IEEE 1451.

The IEEE 1451 family of standards defines a common interface for 'smart transducers' allowing them to be adaptable to virtually any fieldbus or control network on the market. IEEE 1451 has a wide range of industrial applications, but its event-driven communication is inadequate for use in the real-time deterministic systems that are becoming increasingly prevalent. In this presentation, a real-time enhancement of the IEEE 1451 architecture is introduced. The time-driven (time-triggered) communication is implemented through the replacement of the defined transducer interface with TTCAN, which is a time-triggered development of the existing CAN standard. This presentation outlines the IEEE 1451 and TTCAN standards and presents a prototype system that demonstrates that a real-time, deterministic IEEE 1451 solution is both workable and feasible. This work was presented at the 'Sensors and their Applications XII' conference at the University of Limerick, September 2003.
