Abstract :
The essential properties of smart sensor error correction algorithms and calibration procedures according to the IEEE1451.2 standard are presented. Using a modern microcontroller design, it is possible to implement STIM in a single chip design, but due to complexity of error correction and calibration algorithms it is preferable to distribute these tasks between several processors available in a network. A description of a simple calibration algorithm intended for implementation in modular STIM (smart transducer interface module) design is given. Other calibration and error correction approaches were tested on designed and fabricated smart sensor networks. Their implementation is discussed and the results of the most promising bivariate spline approximation algorithm are presented.
