A design of IEEE 1451.2 compliant smart sensor based on the Nios soft-core processor

Abstract

Since 70s of last century, Internet technology has been greatly developed, and embedded Internet is a current trend in modern measurement and control systems. An IEEE 1451.2 compliant smart sensor based on embedded Internet technology is designed, prototyped and experimentally tested in the paper. This smart sensor designed has a compliant smart transducer interface module (STIM) and network capable application processor (NCAP) defined in IEEE 1451 standard and has developed in a hardware description language, including the microprocessor. The design has been implemented in a field programmable gate array (FPGA), based on the Nios soft-core Processor. The design provides a reconfigurable and reprogrammable solution to remotely monitor and control the field devices over Internet.
