In order to realize rapid fault diagnosis of machinery device

and improve the stability of the device

a long-distance fault diagnosis system of machinery based on Labview is designed.The integrated structure and function of the system are introduced.Especially

the crucial technologies in the design of hardware and software subsystem are discussed.The structure mode of ratiocination machine is built by syncretizing the method of clustering analysis

RBF neural networks and fuzzy reasoning technology

and the algorithm of fault diagnosis is put forward

which boosts the rate and accuracy of diagnosis.Finally

the application of the system is introduced by the two working modes: local online inspection diagnosis and long-distance fault diagnosis.The practice demonstrates that the system has the virtues of rapid and accurate diagnosis and working stably

and possesses the great value of engineering application.
