Abstract :This system realizes intelligent online dynamic detect and data processing for electric machine of washing-machine, using Distributed Control System, realizes the online dynamic detect of performance parameter:80V low voltage startup,286V insulation between circles, empty load 220V running, stop-rolling, bear voltage, yawp, and so on, and could be show or statistics,otherwise, the system mining the data of Electric machine detected by K-Cluster arithmetic basic on clustering, analyse the work position that easy trouble on the rules of data, offer the grounds for effect management, improve production efficiency and product quality. Keywords:Intelligent Online Dynamic detect; Distributed Control System;data mining
