The Suzhou Submission Form

1.  The Invention

 

Title: The method for MEMS accelerometer noise reduction used in Condition Monitoring System of Large Rotating Machines
The problem the inventor(s) wanted to solve: Decreasing the cost of the vibration based condition monitoring systems by the use of silicon MEMS accelerometers

Description: The method allows decreasing significantly noise level of MEMS sensors. It is based on adaptive subband filtering employing Adaptive Line Enhancer. Two new adaptive algorithms simplify hardware implementation of the filter.
Presentation: POSTER
Fields of application: condition monitoring of machines, vibration based maintenance

Advantages: vibration monitoring systems cost decrease, high efficiency in field of wide band noise reduction, utilization of new algorithms, simple hardware implementation, suitable for denoising any kind of wideband signals (especially containing a lot of harmonics)

Stage of development: prototype
