FPGA - Vibration Analysis

It sounds like a great application for "machine learning". With a fleet that size, the investment will be worth it. Choose a platform that can handle machine learning as well as signal characteristics characterization, such as FFT.

A Raspberry Pi 5 might be a good low cost platform.

A SmartFLY Kendryte K510 CRB-KIT might be good too, but maybe a steeper learning curve.

Dear Shabaz,

I am filled with veneration over your recommendations. Indeed this is a "STAB AT FINDING THE RIGHT DIRECTION".

I believe by this move the senior management would be convinced that the Engines / Gearboxes / Rotating Machinery on board the Vessels do require a Condition Based Monitoring System. 

Could you kindly help me in integrating a VIBRATION RECORDING DEVICE ! I would wish to build one myself. 

 What I can envisage is a Piezo Sensor + ADC + Some sort of recording contraption / SSD.

I could analyze the recordings on MATLAB later; a couple of weeks later when ships return to harbor after patrol.

Sincerely,

Dear Dougw,

I am not at all savvy on such electronics ! I grew up on Thermionic Tubes. 

The idea of "Machine Learning" sounds very good. Kindly elaborate over "Choose a platform that can handle machine learning as well as signal characteristics characterization, such as FFT."

I am an avid learner. Shall appreciate all help.

Sincerely,

Surely the people at Edge Impulse would be happy to learn about your use case and accompany you.

The problem you will have with trying to do it all yourself is that it is a LOT of work.

I've been involved in a similar project - it took maybe 5 man years to get to an 8 channel recorder with signal conditioning, IEPE inputs, FPGA doing some filtering but not FFT.

This doesn't include all the PC software at the other end of the Ethernet cable.

One of the problems with doing your own hardware is that you then will end up doing all your own software.

Hello Michael,

I do not have years to continue with this Project. I need just two channels for the main engine, to begin with. This is just to set a precedence. Once the latter is accepted as a necessary part of the Propulsion System outfit, then time would not matter. We could hire a bigger team to help through.

I want a set / recording device to be installed on one engine first. This is to draw attention of the senior management towards something that is beneficial. This does not exist at the moment.

PC Software for analysis, MATLAB should serve the purpose.

My aim, at present is to apprise the senior management over the need for such a system to prevent frequent breakdowns and save on costs and time both. Start small time !

Dear Javagoza,

Thanks; very interesting. I shall take a serious look into it. Your suggestion is very correct.

Sincerely,

Dear Jan,

That is wonderful. I shall request him for help. 

So inching ahead ! 

I am hopeful someone would also help with the recording part too. 

Thanks. Obliged.

Sincerely,
