Implementation of an IEEE 1451 Smart Quartz Tuning fork Temperature Transducer for Real-time Distributed Measurement and Control System

摘要

The IEEE 1451 smart transducer interface standards was created to provide the common interface and enabling technology for the connectivity of transducers to realtime distributed measurement and control system. The standardized TEDS specified by IEEE 1451.2 allow the self-description of sensors and the interfaces provide a standardized mechanism to facilitate the 'plug and play" of sensors to networks. A smart high-performance quartz tuning fork temperature sensor (QTFS) with a prototype IEEE 1451 Internet interface was implemented by Microprocessor PIC16F877. A software environment has been developed to realize the full STIM functionality, this STIM implementation is interfaced to a NCAP to demonstrate a remote temperature measurement and control application, operating over the world-wide-web. Experiment and results of the demonstration project have proved that the smart transducers possess high-performance and enable Internet access of networks.
