Abstract

At present, Micro controller and peripheral devices concatenated balance measurement system, which is in low integration level and large measurement error, and have a lot of obstacles to implement intelligent milling on the high speed occasions. Firstly, this paper discussed the way to implement intelligence milling balance measurement system based on embedded (Open Multimedia Application Platform, OMAP), OMAP dual-core architecture could reasonably plan the general task of the balance test system according to its advantages, and used ARM subsystem to complete control function of the balance mechanical’s electrical system; DSP subsystem realized digital signal processing and calculation of unbalance. Secondly, in order to accurately extracted the characteristics of unbalanced signal from strong interference sources and effectively restrain signal interference, the software designed and completed tracking digital band pass filter based on harmonic wavelet package. Used the harmonic wavelet packet with the feature of infinite segmentation for the signal in the frequency domain to extract the characteristics of any period of weak signal. The simulation results showed that the digital band pass tracking filter based on harmonic wavelet packet can effectively restrain the nearly frequency signal interference, improve the signal-to-noise ratio, restore the initial unbalance signal characteristics. In high-speed situations (15000RPM above), the system can achieve high efficiency, high precision and intelligence targets.
