Development of a middleware for exploring practicality of IEEE 1451 protocol family

The interfaces of NCAP and physical sensor network have been realized on the IEEE 1451 middleware for exploring their practicality of IEEE 1451 protocol family based on the well-developed CANOpen and Zigbee. The functions of IEEE 1451 middleware have request-reply command translation, node discovery, surveillance, failure diagnosis, and break detection to simplify the transducer data access for NCAP application tasks. The proposed IEEE 1451 middleware can eventually integrate the existent sensor network to extend the coverage of IEEE 1451 protocol family.
