Abstract:Aimed at eliminating negative features of the conventional fault detection and diagnosis,this paper proposes the cloud model method designed for fault detection and diagnosis for coal preparation plant jigging system,combined with the cloud model ideas and information fusion algorithm.The method involves substituting reasoning mapping algorithm based on one-dimensional cloud model for conventional neural network training process for the consolidation of multi-source information integration to ensure the accuracy of detection and diagnosis and real-time detection simulation.The results show that the system,capable of a higher accuracy identification,a better response to jigging system work,and timely judgments,promises to come into feasible use in fault detection and diagnosis of coal preparation plant jigging system.
Keywords:cloud model  reasoning mapping processer  information fusion  neural network
