The Research On The Convenient On-line Fault Diagnosis System Of The Railway Motorcycles' Traveling Part

For long time, the railway motorcycles' traveling part break-down( especially the outburst break-down) is the latent threat on the railway transit because of it's construction sophisticating, bad situation of work environment etc. With the main technology of vibration diagnosis,this paper put up distilling and analyzing the signal of the railway motorcycle, investigating and exploiting with the aim of having the off-line synthetic precise diagnosis ability.At firt the thesis discussed the exploitive signification of the on-line fault diagnosis system of the railway motorcycles' traveling part,then summarized the theory and technology wich were be used during the studying.According to the actuality and position of the research in home and fremdness,the paper brought up a convenient on-line fault diagnosis system of the railway motorcycles' traveling part. The system pass the combination sensor to withdraw the signal of the object vibration and wallop,temperature,rotate speed etc. After handle the empress through the hardware and software, the signal can gain vibrational energy and frequency. With special judge of fault diagnosis according to constitute the knowledge base with of the diagnosis expert system, the railway motorcycle's traveling part can be proceeding to synthesize the nicety diagnosis. At the same time, with the DSP on-line diagnosis host computer the system establish and keep that measur-point of precise file, simple file and report or clearance file etc.Due to have off-line data manage function,the system can find out the history of the being monitored object or proceed to analyse the trend and synthesize the nicety diagnosis,thereby achieve the on-line monitoring and the on-time fault diagnosis of the circurotating machine such as railway motorcycle etc which needn't be disjointed.
