| Abstract: | According to the problems to be faced with the implementation of condition-based maintenance of power generation equipments it is pointed out to analyze the various kinds of data reflecting the equipment conditions by the decision tree classification algorithm in the data mining and to mine the classification rules of equipment conditions. A feasible method, i.e., how to construct the training sample set of equipment conditions, is put forward. The concrete procedures to implement the decision tree algorithm by SQL language are described in detail. By means of practical examples the correctness and effectiveness of the presented algorithm are proved. |
