Simulation Research of Sensor Fault Detection

The thesis mainly introduces the application of sensor fault detection with the Continuous Wavelet Transform and BP Neural Network, and discusses the method of fault detection by combining the Continuous Wavelet Transform with Neural Network. In the end, the factual examples are simulated with simulink toolbox and the correlative signal processing toolbox of the software of Matlab,and satisfactory results are obtained,which testifies the feasibility of these ways above.
