Equipment fault diagnosis is an important means to ensure safe operation of equipment. Structured storage of the fault data model is used in this paper. And an improved Apriori algorithm is proposed accord-ing to the characteristics of fault data and the deficiency of Apriori algorithm, combining the MapReduce programming model, which reduces the number of scanning and improves the efficiency of the algorithm. The correlation is exhumed among equipment inspection status by mining the association rules of fault data in cloud computing environment, which provides reliable support for equipment maintenance and management. At last an example is given to prove the feasibility.
