Dsp-based Integrated Data Acquisition And Processing System

Data acquisition and processing is a important branch of information science. It's a compositive subject based on sensor,signal processing, electronics,computer and so on. This paper achieved a data acquisition and processing system based on Data Signal Processor(DSP). It mainly apply for flight parameter,intellgent building and industrial control etc. This system integrates multi-processor, bases on DSP TMS320LF2407A to manage the data, bases on neuron chip FT3150 to communicate between each other, bases on single-chip-processor AT89C52 to achieve local data acquisition. It not only study how to design the hardware and software but also analyse and minish the error. The system was designed based on modularization, so it is convenient for fixing and maintenance. The local test indicate this system satisfied basically designing requirement.
