Rotating mechanical system is the key equipment in the industrial production. To avoid the important mechanical equipment being cut off due to accident, it is necessary to study online testing technology and on-line trend forecasting technology. The application of the sensor in this technology is introduced. The time domain signal and the spectrum analysis chart of the sensor detection are given. The composition of the trend forecasting system of the mechanical system including a series of sensors is also introduced.
