设备故障信息融合问题的思考

The Consideration on Information Fusion of Equipment Fault

认为信息融合技术是工程需求和科技发展的必然结果，给出了信息融合前应当去噪的信息熵解释，探讨了对信息融合方法的要求，提出了融合－识别的构架问题并提出了三类融合－识别构架，对现有的一些信息融合方法进行了回顾和小结。

As a result of the engineering requirement and technology development,the information fusion is becoming a focus in equipment fault diagnosis. In the paper the concept of information entropy is given to explain the necessity to eliminate the noise before fusing information,the general requisition to the measurements of information fusion is discussed,the three kinds of frame of the fusion-identification are offered,and a series of measurements of information fusion are reviewed and summed up briefly.
