Based On Ethernet Remote Monitoring Of Motor Failure Experimental Platform Development

With progress and electrized modern science and technology degree rise, electric motor, the quilt already applies to each commercial run fields broadly. Malfunction developing a set of electric motor therefore long-range experiment platform monitoring, now that being able to know electric motor basic structure more well, can have fundamental a few digital signal processing method in hand, can study fundamental long-range monitoring a technology, have importance in the process of automation special field teaching at the same time.Originally, the thesis thins out a short circuit first circle from common stater of squirrel-cage type asynchronization electric motor, the rotator cuts off fundamental malfunction electromagnetism relation such as strip, gas crack partiality starting off, stater electric current frequency spectrum is hit by constitutive various characteristic frequency creation mechanism under having analyzed different malfunction condition in depth. Then proposed the electrical machinery under stable state movement four kind of failure detections method principle and the characteristic, respectively be conventional frequency spectrum analytic method, based on Hilbert module spectral analysis asynchronous motor rotor failure detection method, based on Park's vector transformation stator failure detection method, based on average instantaneous power spectral analysis mouse cage type asynchronous motor failure detection method. As well as electrical machinery when load undulation failure detection wavelet analytic method.And electric motor malfunction having built build aether net-based long-range monitor experiment platform , adopt the Hall sensor to collect the three-phase electric current and voltage signal, long-range monitor a module owing to C/S pattern , adopt the be geared to the needs of connection TCP agreement Socket way programming, the board developing holds implantation style as the server packing the data , PC machine adopt WinSock to package the kind programming by the fact that aether net controller CS8900A transfers the data bag, build the customer machine taking-over data document, the signal carries out the result analysing , exporting analysis on the electric motor with malfunction detecting method brought forward by the main body of a book.
