According to the present invention, a plurality of diagnostic signals can be obtained in a short blasting impeller motor facility, and the reliability can be examined by comparing the signals. The present invention enables accurate diagnosis and prediction by analyzing and diagnosing while monitoring in real time. The present invention relates to a state diagnosis apparatus and method, and more particularly, two or more signals among vibration signals, current signals, voltage signals, flux signals from a motor, and acoustic emission sensor signals, which are signals for facility diagnosis of a short blasting impeller motor.
