Fault prediction method and device thereof for rotation equipment

The invention relates to a fault prediction method and a device thereof for rotation equipment. The method comprises the following steps (1) setting a testing device comprising a power supply module, a sensor, a data collection module, a data sorting module, a time sequence predicting module, a gray prediction module, a combined prediction module, a frequency component amplitude value prediction module, a self-adaptive optimization selection module, a display module and a system control module; (2) collecting vibration signals suitable for four prediction modules by the data collection module to be used as historical data; (3) using the data collection module for collecting the vibration signals under various conditions in real time to be used as current data; (4) using a trend predication method for analyzing the stored data; (5) after analyzing and processing vibration signals collected in a next moment, comparing the vibration signals to results obtained by the trend predication method; and (6) obtaining an optimum prediction model after the comparison. The invention adopts the fault prediction device in a modularized structure, can adapt to the requirements of different rotation equipment, and can realize the real-time on-line prediction on the state of the rotation equipment. The invention can be widely applied to the fault prediction detection analysis of various kinds of rotation equipment.
