Design of TEDS writer, reader and testing system for transducer interface modules based on the IEEE 1451 standard
The commercial benefit of transducer industry is very large potentially. The IEEE 1451 standard provides compatibility among the products from different transducer manufacturers. The IEEE and NIST developed this standard for smart transducers. In this thesis, I focus on developing IEEE 1451 TEDS Writer/Compiler, TEDS Reader and TIM Tester etc. and study the following topics: (1) IEEE 1451 TEDS Writer/Compiler and TEDS Reader Design, each with the following seven function blocks: (a) Meta TEDS Writer (Access Code 1); (b) eta ID TEDS Writer (Access Code 2); (c) Transducer Channel TEDS Writer (Access Code 3); (d) Channel ID TEDS Writer (Access Code 4); (e) Calibration TEDS Writer (Access Code 5); (f) Calibration ID TEDS Writer (Access Code 6); (g) XdrcName TEDS Writer (Access Code 12); (2) IEEE 1451 TEDS (Version 1997) Testing system based on the board of NCAP/Ethemet With TCP/IP Through RS232; (3) Design of TIM Tester based on IEEE 1451 Standard; (4) Sensor Data Calibration. Analysis is provided on these topics and a test TIM with three channels is designed for testing purpose of this standard. The TEDS Writer, TEDS Reader and TIM Tester contribute originally to transducer industry field.
