Study of Online Automative Detection Based on the Vibration Signal of Dual-Processor

摘要

According to the harmful vibration existed in the engineering technology fields especially under the fault condition, a wide bandwidth vibration fault diagnosis system is introduced, which can obtain the acceleration, rate and displacement simultaneously. This instrument composes of dual-processor OMAP5912.By using its DSP core the instrument is able to analyze the vibration signals under operation, transfer the result to ARM core, then display the result by LCD, besides the addition of extensible fault diagnosis expert system. Through the simulation and experimental detection, to verify the vaLidity of the methods detecting the bandwidth vibration signal from 20Hz to 10KHz.
