During detection of asynchronous motor rotor-bar brokenfault, the signal of current was reconstruct after decomposed by best wavelet packet and adaptive filtered.
在异步电机转子断条故障检测中，将原信号最优小波包分解，经自适应滤波后再信号重构。

The theory, hardware and software are discussed. A brokenfault in gearbox is diagnosed by the system and the result shows that the system is scientific and effective.
