| Abstract: | The article shows a new and convenient AI system for detecting combustion engine technical state.It makes the use of noise sensor to pick up the noise from the engine,then uses FFT for getting frequency band.The error of FFT methodwas analysed theoretically and the correction method was given.Fuzzy model is made up on analysing the feature of frequency band,Information collected,and the article also gives the method expressed by Turbo C which describes internal combustion engine technical state.The method can sample and analyse the engine noise in site,thus the working states of 24 engines can be distinguished correctly. |
