Abstract： The space data processing center should be on-line running without stop in highly reliability and availability, so this paper presents a fault prediction method based on rule and fault tree, and designs the fault prediction system for processing management system of space data processing center. Firstly, the architecture of fault detection is designed for software and hardware of the space data processing center. Secondly, the derivation method is presented based on fault tree and rule of visualization to realize the fault function of the processing management system. Then, based on the fault detection, the fault prediction method is proposed using auto-selection method and artificial method, after the learning method is used between prediction result and historical data. At last, the application of the system is realized with the using of the method presented in this paper. On the comparison of the prediction result with the real data, the method of this paper is proved effective and efficient.
