Vibration Signal Acquisitor and Analyzer Based on DSP

摘要

Based on digital signals processor DSP a novel vibrant data acquisition and analysis system is designed. Its main characteristic is that it adopts piezoelectric accelerated sensor to collect signal, charge transform, program magnify and program filter circuit are served as signal modulation circuit, and adopts major-minor process structure to process signal. DSP is main processor, and PC is secondary processor in the system. The experiments prove that the system can satisfy with the need of mechanic vibration data collection and analysis.
