Real-time Vibration State Monitoring System and Monitoring Method Thereof

A real-time vibration state monitoring system, comprising:

• a linear motor including a vibrator which generates vibration and a working coil which interacts with the vibrator to generate induced electromotive force;
• a signal generating module for outputting a drive signal to drive the linear motor to vibrate;
• a working parameters feedback module connecting with the linear motor electrically, for monitoring and returning the real-time induced electromotive force of the linear motor;
• a calculating module connecting with the working parameters feedback module electrically for calculating and outputting the speed, the acceleration and the amplitude of the vibrator in accordance with the induced electromotive force, the power coupling coefficient of the working coil and the initial position of the vibrator;
• an initial position recording module connecting with the calculating module electrically for recording the initial position of the vibrator, updating the initial position of the vibrator regularly in accordance with the calculation result and outputting the initial position to the calculating module;
• a signal control module connecting with the linear motor, the calculating module and the signal generating module electrically and respectively for controlling the amplitude of the linear motor by adjusting the drive signal in accordance with the calculation result.
