Due to its high complexity and accuracy, the faults of aeroengine sensor can not be described with precise mathematical model and it is hard to detect the faults using traditional redundant method. Focus on this problem, a big data-deep learning based model is established to detect the faults of sensor of the engine air exhaust temperature. The classified model using deep belief network(DBN) is built firstly and is trained using a great number of data collected by flight parameter recorder. The model is able to classify the fault through feature learning layer by layer. The results of simulation experiment show that the accuracy with artificial feature extraction is 98% while 96.6% without it. The accuracy of this model is higher than the model using BP neural net and support vector machine(SVM) in both conditions which shows the superiority of the DBN algorithm in sensors fault diagnosis.
