Paper Abstract

Electrical measurement system in milling balance machine currently consists of micro-controller and peripheral devices. The structure has the problems which include low integration, single signal processing algorithms and great measurement error. Therefore, electrical measurement system in milling balance machine based on embedded optimization is presented in the paper. Firstly, the device control electrical measuring system by ARM subsystem of OMAP dual-core architecture and DSP subsystem realizes digital signal processing and unbalance computing. Also, the low-pass filtering circuit is designed for solving frequency interference. Secondly, the system implement digital band-pass tracking filter based on harmonic wavelet packet. Thirdly, the system extracts any period of weak signal characteristics using the unlimited segmentation features harmonic for wavelet packet signal in the frequency domain. Simulation results show that the system effectively inhibits nearly frequency signal interference, improves signal to noise ratio, and reduces the initial imbalance signal characteristics. And test results improve that precision indexes and technical specifications could meet the design goals.
