Abstract：Aiming at various problems existing in repairing of pouring and picking equipments（PPE），detailed analysis on situations andworking features of PPE was carried out. These problems including complicated fault types，dispersive equipments and strict standard forcontinuous work can not be solved by the traditional fault diagnosis technology（FDT）based on PC，because the FDT is lack of flexibility. Based on analysis，the solution which adopts vibration as main index was confirmed. Besides，a new kind of hand-held state monitoring

and fault diagnosis system（SM-FDS）based on embedded technology was put forward. With the help of multi-channel data collection technology，hand-held circuit check real-time data collection and signal analysis component（SAC），signal analysis component（SAC）library and the graphical user interface（GUI）component library which was configurable and space-saving were established. A monitoring system with upper-lower dual-CPU which has low power consumption was constructed. The results indicate that this system which monitors pouring and picking equipments（PPE）accurately and stably is promising.
